Constitutional Law

No operative constitution since 2021

The 2004 Constitution was suspended after the August 2021 takeover and has not been replaced. Authority rests on decrees of the Islamic Emirate interpreted through Hanafi jurisprudence, with no legislature, no constitutional court and no published consolidated legal code.

Practitioners face a genuine gap: pre-2021 statutes are sometimes applied where they do not conflict with the Emirate's reading of sharia, but there is no authoritative list of what survives. The Supreme Court has been reconstituted with clerical judges, women are barred from practising law, and the Independent Bar Association was dissolved. Any assertion about enforceable Afghan law in 2026 carries real uncertainty, and this atlas does not paper over it.

The 1998 Constitution and the 2016 justice reform with judicial vetting

Albania is a parliamentary republic under the 1998 Constitution. The 2016 justice reform amended it substantially, creating new governance bodies and a transitional vetting process that re-evaluated every judge and prosecutor.

The vetting process left courts, including the Constitutional Court, without quorum for extended periods, which affected case timelines.

A 2020 constitution revised after the Hirak protests

The 2020 revision, approved by referendum on very low turnout, followed the 2019 Hirak movement and Bouteflika's resignation. It limits the President to two terms and creates a Constitutional Court in place of the former Council.

The substantive novelty of the 2020 text is the conversion of the Constitutional Council into a Constitutional Court with a widened power of review, including a route for individuals to raise constitutionality through the courts, which did not previously exist. Whether that route is used meaningfully is the practical question. The two-term presidential limit restored a cap that had been removed in 2008 to permit a third Bouteflika term, and that removal was the proximate trigger for the 2019 protests. The military's constitutional role and the language on deploying forces abroad were also new. Turnout of roughly 24 per cent on the referendum is a material fact about the text's legitimacy that neutral description should record.

The 1993 Constitution and a parliamentary co-principality

Andorra became a constitutional parliamentary co-principality with the 1993 Constitution. The President of France and the Bishop of Urgell remain joint heads of state as Coprinces, while legislative power rests with the Consell General.

Lleis qualificades cover fundamental matters and need an absolute majority, so they cannot be amended by an ordinary legislative majority.

2010 Constitution with a strong presidency and a Constitutional Court

The 2010 Constitution replaced the 1992 revision and concentrates executive power in a President who is the head of the winning party's list rather than separately elected. Title II contains fundamental rights, and the Tribunal Constitucional exercises both abstract and concrete review. The Supreme Court remains the apex of the ordinary courts.

The 2010 text abolished direct presidential elections in favour of automatic investiture of the leading party's head of list, which is the single most consequential feature of Angolan constitutional design. Constitutional review is concentrated rather than diffuse: ordinary courts cannot disapply a statute themselves and must refer.

1981 Constitution with Barbuda's distinct land regime

The Antigua and Barbuda Constitution Order 1981 created a parliamentary monarchy with a Governor-General, a bicameral Parliament and an independent judiciary, with fundamental rights in Chapter II enforceable in the High Court. A 2018 referendum to replace the Privy Council with the Caribbean Court of Justice was rejected, so the Privy Council remains the final court. Barbuda, though not a separate state, has a Barbuda Council and a distinctive communal land system that has generated significant constitutional litigation.

The Barbuda land question is the live constitutional issue: the Barbuda Land Act 2007 vested land in the people of Barbuda communally, and amendments permitting freehold sales were challenged as an unconstitutional deprivation of property. Advisers on any Barbuda project must check the current state of that litigation rather than assume the amended act governs, because the outcome determines whether a freehold title can be granted at all.

1853 Constitution with constitutionalised human-rights treaties

Argentina is a federal republic under the 1853 Constitution, extensively reformed in 1994. Article 75(22) grants a list of international human-rights treaties the same rank as the Constitution itself, so the American Convention and the ICCPR are directly enforceable domestic law rather than mere international obligations. Rights are protected by the amparo action, habeas corpus and habeas data, all of which the 1994 reform wrote expressly into Article 43.

The constitutionalised-treaty rule in Article 75(22) is the distinctive feature of Argentine constitutional law. Because those instruments sit at constitutional rank, the Supreme Court applies Inter-American Court case law when interpreting domestic rights, and litigants routinely plead the American Convention directly. Habeas data, also in Article 43, gives any person the right to learn what data public or private registries hold about them and to demand correction or deletion.

A parliamentary republic after the 2015 constitutional referendum

The 1995 Constitution was fundamentally amended by referendum in December 2015, converting Armenia from a semi-presidential to a parliamentary republic. The transition completed in April 2018. The Constitutional Court reviews the conformity of laws with the Constitution.

Since the 2015 amendments took full effect the President is elected indirectly by the National Assembly for a single seven-year term and holds a largely ceremonial role. Executive power rests with the Prime Minister and government, which is accountable to the National Assembly. The Constitutional Court can be approached by individuals through a constitutional complaint after ordinary remedies are exhausted, which is a meaningful route in practice. Armenia is a Council of Europe member, so the European Convention on Human Rights is part of the applicable framework and the Constitutional Court engages directly with Strasbourg jurisprudence.

1901 Constitution with no national bill of rights

A federal common-law system under the 1901 Constitution, notable for having NO national bill of rights. Rights protection is structural rather than enumerated: the separation of judicial power under Chapter III, a handful of express guarantees, and implied freedoms the High Court has drawn from the text.

There is no constitutional bill of rights. The express guarantees are narrow — trial by jury for indictable Commonwealth offences (s. 80), just terms for acquisition of property (s. 51(xxxi)), freedom of religion (s. 116) and freedom from interstate discrimination (s. 117). Everything else is either an implied freedom, most importantly the implied freedom of political communication recognised in Lange v Australian Broadcasting Corporation, or ordinary statute. Because implied freedoms limit legislative power rather than confer personal rights, they cannot be sued on directly the way a charter right can. Only the ACT, Victoria and Queensland have human-rights statutes, so the protection available depends on which jurisdiction a person is in.

A real constitutional court — with individual complaint and statute annulment

Unlike its western neighbours, Austria has a powerful Constitutional Court (Verfassungsgerichtshof) that can annul statutes for unconstitutionality. The federal constitution is spread across the core B-VG and many separate constitutional acts, and since 2015 individuals can bring a direct complaint (Parteiantrag) challenging a law applied in their case.

The scattered nature of Austrian constitutional law means important guarantees sit outside the B-VG itself, and the ECHR has constitutional rank, giving Convention rights unusually strong domestic force. The individual complaint has widened access to constitutional review.

A strong presidential republic under the 1995 Constitution

The Constitution adopted by referendum in November 1995 establishes a presidential system with extensive executive authority. Amendments in 2002, 2009 and 2016 lengthened the presidential term to seven years, removed term limits and created the office of First Vice-President.

Executive power is concentrated in the President, who appoints the Cabinet of Ministers, nominates judges and can dissolve the National Assembly in defined circumstances. The 2009 referendum removed the two-term limit and the 2016 referendum extended the term from five to seven years and created the First Vice-President position. The Constitutional Court reviews legislation and hears individual complaints after exhaustion of ordinary remedies. Nakhchivan's autonomous status is constitutionally entrenched and gives it a separate legislature, though its laws must conform to national law.

A 2002 constitutional monarchy with a bicameral legislature

The 2002 Constitution converted the emirate into a kingdom with an elected Council of Representatives and an appointed Shura Council of equal size.

The 2002 constitution's defining feature is that the appointed Shura Council has the same forty seats as the elected chamber and its consent is required for legislation, which means the elected chamber cannot legislate alone. This was the core grievance of the 2011 protests and remains the central constitutional argument in Bahrain. The King retains power to legislate by decree between sessions. The National Action Charter of 2001 that preceded the constitution was endorsed overwhelmingly in a referendum, and the divergence between what the Charter promised and what the 2002 constitution delivered is essential context for any account of Bahraini constitutional politics.

Written constitution with a basic-structure doctrine and a 2024 rupture

The 1972 Constitution is supreme and the Appellate Division may strike down amendments that damage its basic structure. Following the August 2024 uprising an interim administration took office and constitutional reform is under active consideration.

Part III guarantees fundamental rights enforceable by writ under Article 102, and Bangladesh's public interest litigation tradition is genuinely active. The caretaker-government provision was abolished by the Fifteenth Amendment, a change central to the political crisis that followed. Readers should treat the constitutional position as in flux: reform commissions were sitting through 2025 and their proposals may alter provisions cited here.

1966 Constitution, a republic since 2021, with the CCJ as final court

The Constitution of 1966 remains in force, but Barbados became a parliamentary republic on 30 November 2021 through the Constitution (Amendment) (No. 2) Act 2021, replacing the monarch with a President as head of state. Barbados was also the first state to accept the appellate jurisdiction of the Caribbean Court of Justice, in 2005, so appeals no longer go to London. A Constitutional Reform Commission has been working on a wholly new constitution.

The 2021 transition was deliberately narrow: it changed the head of state and related offices but left the structure of government, the courts and the rights provisions intact, so pre-2021 constitutional case law continues to apply. Accepting the CCJ's appellate jurisdiction has had a more visible doctrinal effect, because the Court has been willing to depart from Privy Council authority where it considers the regional context differs.

A 1994 constitution reshaped by the 2022 referendum

The Constitution of 1994 was amended by referendum in 1996, 2004 and again in February 2022, which created the All-Belarusian People's Assembly as a standing constitutional organ and removed the previous neutrality and nuclear-free commitments.

The individual complaint added in 2023 requires exhaustion of all remedies and consent of the referring body in practice, so it has not functioned as an accessible remedy.

One of the oldest constitutions in force, reshaped into a federation

The Constitution of 7 February 1831 still governs, but six state reforms since 1970 turned a unitary kingdom into a federation of Regions and Communities, and the text was renumbered in a coordinated version in 1994. Federal statutes, regional decrees and community decrees hold equal rank within their own competences.

There is no individual constitutional complaint. A citizen reaches the Constitutional Court either by an annulment action within six months of publication, which requires a personal and direct interest, or indirectly by persuading the trial court to refer a preliminary question.

The only common-law state in Central America, final appeal to the CCJ

Belize is a common-law jurisdiction with a Westminster constitution of 1981 and English common law and equity in force. It replaced the Privy Council with the Caribbean Court of Justice as final appellate court in 2010, and its courts have delivered landmark rulings on Maya customary land title and on the decriminalisation of same-sex conduct.

Constitutional claims start by originating motion in the Supreme Court, with appeal to the Court of Appeal and then the CCJ. There is no general limitation period for constitutional redress, but delay affects discretion. The Maya land litigation remains in the implementation phase.

1990 Constitution with a Cour constitutionnelle that individuals may petition directly

The Constitution of 11 December 1990 emerged from the 1990 Conférence nationale, the model later copied across francophone Africa. Its Cour constitutionnelle is unusually accessible: any citizen may petition it directly over a rights violation, and it has struck down presidential acts. A 2019 revision extended terms and altered eligibility.

Benin's 1990 Conférence nationale souveraine ended the Marxist-Leninist Kérékou state and produced a constitution whose distinctive feature is standing: Article 122 lets any citizen challenge a law or administrative act directly before the Cour constitutionnelle, without counsel. That has made the Court a genuine actor rather than an abstract reviewer, though the 2019 revision and the exclusion of leading opposition candidates from subsequent elections have drawn sustained criticism.

2008 Constitution created a monarchy that can be removed by parliament

Bhutan's written Constitution took effect in 2008, converting an absolute monarchy into a democratic constitutional monarchy. It uniquely provides for abdication of the King by a two-thirds parliamentary resolution and mandatory retirement at 65.

Article 5 obliges the state to maintain at least sixty percent forest cover in perpetuity — a constitutional environmental floor with few parallels anywhere. Gross National Happiness is a constitutional objective under Article 9 rather than mere policy. Fundamental rights in Article 7 are enforceable, and the Supreme Court, created by the Constitution, sits as the final constitutional authority.

2009 plurinational Constitution with parallel indigenous jurisdiction

The 2009 Constitution refounded Bolivia as a Plurinational State, recognising 36 indigenous nations and establishing jurisdicción indígena originaria campesina as equal in hierarchy to the ordinary courts. The Tribunal Constitucional Plurinacional resolves conflicts of jurisdiction between them, and its magistrates are elected by popular vote.

The constitutional equality of indigenous and ordinary jurisdiction is Bolivia's most distinctive feature: Ley 073 delimits which matters each may hear, reserving serious crimes and certain subjects to the ordinary courts while leaving community matters to indigenous authorities applying their own norms. Popular election of high-court judges, including the Constitutional Tribunal, is also close to unique internationally.

The Dayton constitution, two entities and a court with international judges

The Constitution is Annex 4 of the 1995 Dayton Peace Agreement. It creates a state with limited competences alongside two autonomous entities and the Brčko District, with a Constitutional Court that includes three judges appointed by the European Court of Human Rights.

Always establish the level of government first: state, entity, canton or Brčko District, because each has its own legislation and courts.

1966 Constitution with a Court of Appeal apex and entrenched Chapter II rights

Botswana has kept one constitution since independence in 1966, unusually for the region. Chapter II contains justiciable fundamental rights, and the Court of Appeal sits at the apex above the High Court. There is no separate constitutional court; constitutional questions reach the Court of Appeal through the ordinary hierarchy. Ntuli and Attorney General v Dow (1992) established that the Constitution is read purposively rather than literally.

Botswana's constitutional order is notable for continuity: a single 1966 text, amended but never replaced, applied by a judiciary with a strong record of independence. The House of Chiefs (Ntlo ya Dikgosi) is an advisory body on customary and tribal matters rather than a legislative chamber, which keeps customary interests inside the constitutional structure without giving them a veto.

The 1988 Citizen Constitution with direct constitutional actions

Brazil's constitution is long, detailed and rights-rich. The Supreme Federal Court hears abstract review actions brought by designated bodies as well as individual appeals.

Judicialização da saúde — individual court orders compelling the state to fund treatment — is the most visible consequence of enforceable social rights.

An absolute monarchy under a continuing state of emergency since 1962

Brunei's 1959 Constitution vests full executive authority in the Sultan, who is also Prime Minister. A state of emergency proclaimed in 1962 has been renewed every two years since, allowing rule by emergency order. The Legislative Council is appointed and advisory. Brunei is the only Southeast Asian state with no elected national legislature.

The Sultan is head of state with full executive authority and legislates by Order under the emergency powers. Malay Islamic Monarchy (Melayu Islam Beraja) is the official state philosophy. The Legislative Council is appointed by the Sultan and does not control the executive. There is no justiciable bill of rights and no judicial review of the Sultan's acts. Because law is made by Order rather than statute in the ordinary sense, the Government Gazette is the authoritative source. The emergency proclamation is the constitutional basis for much ordinary legislation, not an exceptional measure.

The 1991 constitution with an individual complaint added in 2023

The Constitution of 1991 created a unitary parliamentary republic. The 2023 amendment finally opened the Constitutional Court to individuals, who may now challenge a statute applied against them after final judicial proceedings, alongside referrals by the Ombudsman and the Supreme Bar Council.

The 2023 route is narrow: it attacks the statute, is available only after all ordinary remedies are exhausted, and does not reopen the original judgment automatically.

1991 Constitution suspended in substance by the 2022 Charte de la Transition

The 1991 Constitution remains formally in force but is subordinated to the Charte de la Transition adopted after the January and September 2022 coups. The Charte vests power in a transitional president and a Assemblée législative de transition. The constitutional order is contested and changing, so this entry records the position rather than settled doctrine.

Burkina Faso has had two coups in 2022 alone, and the resulting Charte de la Transition operates as a supra-constitutional instrument in practice while leaving the 1991 text nominally intact. Any statement that the 1991 Constitution simply governs would be inaccurate. This topic is marked as under research because the applicable higher law is genuinely indeterminate, not because the material is thin.

The 2018 constitution, revising the Arusha power-sharing settlement

The 2005 constitution implemented the Arusha Agreement's ethnic quotas — 60% Hutu and 40% Tutsi in the National Assembly and government, with 50/50 in the army. The 2018 constitution retained the quotas but extended the presidential term to seven years, reduced the majority needed to pass legislation and restored a strong prime ministerial office.

Burundian constitutional law cannot be described without the Arusha Agreement: the ethnic quotas in parliament, government and the army were the settlement that ended the civil war, and the 2015 crisis arose precisely over whether the Agreement's two-term limit permitted a third presidential candidacy. The 2018 constitution preserved the quotas while weakening several other Arusha constraints.

A 1993 constitutional monarchy with a Constitutional Council

The 1993 Constitution, produced under the UNTAC settlement, establishes a constitutional monarchy with a bicameral legislature and a Constitutional Council to review conformity of laws. In practice the dissolution of the main opposition party in 2017 and subsequent amendments have concentrated political power, and the Council's independence is widely questioned.

The King is head of state and reigns but does not rule; the monarchy is elective within the royal family. The National Assembly and Senate form the legislature; the Constitutional Council reviews constitutionality. Chapter III guarantees rights including property, expression and equality before the law. Treaties ratified by Cambodia form part of domestic law, and the Constitution references the UN human rights instruments. Constitutional Council referrals are limited to specified officeholders; there is no general individual complaint route. The 2018 lèse-majesté amendment and the 2017 party dissolution law are essential context for any political-rights question.

A 1972 constitution, revised 1996 and 2008, over a bijural legal order

The Constitution of 1972 as revised in 1996 created a Constitutional Council, a Senate and elected regional councils, and the 2008 revision removed presidential term limits. The 1996 text also promised decentralisation, largely unimplemented until the 2019 special status granted to the Northwest and Southwest regions during the Anglophone crisis.

Cameroon's constitutional order is unusual in Africa for governing two received legal traditions at once. The Southern Cameroons, administered by Britain, joined the francophone republic in 1961 and brought the common law with it. The 1996 revision recognised that duality in principle, but the practical erosion of common-law procedure in the two anglophone regions — including the posting of civil-law-trained magistrates to common-law courts — was the immediate trigger of the 2016 lawyers' strike and the conflict that followed.

The Constitution Acts 1867 and 1982, with the Charter and section 33

Canada's constitution is not one document. The Constitution Act 1867 divides powers between Parliament and the provinces, and the Constitution Act 1982 added the Canadian Charter of Rights and Freedoms plus a domestic amending formula, ending the need for a British statute. The Charter is enforced by the courts, which may strike down legislation, but section 33 — the notwithstanding clause — lets Parliament or a legislature override most Charter rights for renewable five-year periods.

Section 1 makes Charter rights subject to reasonable limits demonstrably justified in a free and democratic society, and the Oakes test is how courts decide whether a limit survives. Section 35, which protects Aboriginal and treaty rights, sits outside the Charter and so cannot be overridden under section 33 — a distinction that matters greatly in resource and consultation litigation.

1992 Constitution with a Supreme Court and consistent democratic alternation

The Constitution of 1992, revised in 1999 and 2010, establishes a semi-presidential republic. Cabo Verde has had repeated peaceful transfers of power between the PAICV and MpD, and ranks at the top of African governance indices.

Cabo Verde created a dedicated Tribunal Constitucional only in 2015, having previously vested review in the Supremo Tribunal de Justiça. The archipelago's record of alternation without violence, an independent judiciary and abolition of the death penalty since 1981 make it the strongest rule-of-law performer in the region, and it is not an OHADA member.

The 2023 constitution, replacing the 2016 post-conflict text

The 2016 constitution restored constitutional order after the 2013 Séléka conflict and the transitional period. It was replaced by a new constitution approved by referendum in July 2023, which extended the presidential term to seven years and removed the two-term limit.

CAR is one of the few states where a hybrid internationalised criminal court operates alongside the domestic constitutional order: the Special Criminal Court, created in 2015 with international judges and prosecutors, tries grave crimes committed since 2003, and the Constitutional Court's 2023 jurisprudence on the referendum was itself contested.

The 2023 constitution, following a transitional period after 2021

After the death of President Déby in 2021 a Transitional Military Council suspended the 2018 constitution and governed under a transitional charter. A new constitution establishing a decentralised unitary state was approved by referendum in December 2023.

Chad's constitutional order has been rewritten three times in six years — the 2018 text that abolished the office of prime minister, the 2021 transitional charter, and the 2023 constitution that restored it — so any assertion about Chadian constitutional law requires a date to be meaningful.

1980 Constitution retained after two rejected replacement drafts

Chile remains governed by the 1980 Constitution, heavily amended in 1989 and 2005 and further reformed since. Two attempts to replace it wholesale were rejected by referendum, in September 2022 and December 2023, so the existing text continues in force. The Tribunal Constitucional reviews the constitutionality of legislation, and the recurso de protección gives fast judicial protection of listed fundamental rights.

The two failed referendums are essential context for any current statement about Chilean constitutional law: proposals for a new charter were extensively debated and drafted but neither took effect, and the operative instrument is still the amended 1980 text. The recurso de protección is filed directly with a Court of Appeals and is the workhorse remedy for rights violations, including in health-insurance and environmental disputes.

Party leadership written into a constitution courts cannot enforce

The 1982 Constitution is formally supreme, but there is no judicial review: only the Standing Committee of the National People's Congress may rule on constitutionality. Courts cannot decline to apply a statute, so constitutional rights are not directly litigable.

The 2018 amendment removed presidential term limits and wrote the leadership of the Communist Party into Article 1. Chapter II lists rights — speech, assembly, religious belief, equality — but Article 51 subordinates them to the interests of the state and society, and no court may strike down legislation for breaching them. Constitutional interpretation is a legislative function, exercised sparingly. Practical rights protection therefore runs through ordinary statutes and administrative litigation against agency conduct rather than constitutional claims.

1991 Constitution with the tutela and a strong Constitutional Court

The 1991 Constitution created the Corte Constitucional and the acción de tutela, a rapid remedy any person may bring before any judge to protect a fundamental right. A tutela must be decided within ten days and the Constitutional Court selectively reviews decisions, producing an influential rights jurisprudence including the bloque de constitucionalidad doctrine that incorporates human-rights treaties.

The tutela is the defining institution of Colombian public law: it is filed without a lawyer, before any judge, and its ten-day decision requirement makes it dramatically faster than ordinary litigation, which is why it is used for everything from health-care access to due-process complaints. The Constitutional Court's structural rulings, such as the declaration of an unconstitutional state of affairs, have driven policy change in prisons and displacement.

The 2001 Union constitution as revised in 2018, over three autonomous islands

The 2001 constitution created a Union of three autonomous islands with a rotating presidency between them. The 2018 revision abolished the rotation in its original form, extended the presidential term and removed the Constitutional Court, transferring its functions to a chamber of the Supreme Court.

The rotating presidency was the constitutional device that ended the secession crises of the 1990s by guaranteeing each island the Union presidency in turn. The 2018 abolition of that arrangement, together with the removal of the Constitutional Court, is therefore not a technical amendment but a change to the settlement that holds the state together.

The most accessible amparo in the Americas

The Sala Constitucional hears recursos de amparo with almost no formality: no lawyer, no fee, no prescribed form, and it may be filed in any language at any time. That design produces tens of thousands of filings a year and has made constitutional litigation the ordinary route for enforcing health, environmental and due-process rights.

A handwritten note or an email to the chamber is enough to open a case. Health-related amparos against the CCSS for delayed treatment are the single largest category and are often resolved in weeks.

The 1990 Constitution, a single-chamber Sabor and an active Constitutional Court

Croatia is a parliamentary republic under the 1990 Constitution, revised to shift power from the President to the Government. The Constitutional Court reviews legislation and decides individual constitutional complaints.

The Constitutional Court also rules on the constitutionality of referendum questions, which has shaped several national campaigns.

2019 Constitution with a Prime Minister and expanded rights

The Constitution approved by referendum in February 2019 replaced the 1976 text, retaining the Communist Party as the leading force in society and state while restructuring the executive to create a President of the Republic and a separate Prime Minister. It expanded the catalogue of rights, introduced habeas corpus and due-process guarantees in the text, and recognised private property alongside socialist state property. The Asamblea Nacional del Poder Popular is the supreme organ, with the Consejo de Estado acting between sessions.

Cuba has no constitutional court and no judicial power to strike down legislation: the Asamblea Nacional interprets the Constitution and decides on the constitutionality of laws, so constitutional argument is political rather than justiciable in the way it is elsewhere in the region. The 2019 text obliged the legislature to pass a substantial body of implementing law, which is why so many core Cuban statutes date from 2021 onward.

The 1960 Constitution and the doctrine of necessity

The Constitution of 1960 established a bicommunal republic with a Greek Cypriot President and a Turkish Cypriot Vice-President. After the breakdown of bicommunal government in 1963 the Supreme Court developed the doctrine of necessity to allow the state to function without the Turkish Cypriot participation the Constitution requires.

This is the essential point for anyone working on Cyprus: the Republic of Cyprus is the internationally recognised state for the whole island and is an EU member, but its administration does not extend to the north, and EU law is suspended there under Protocol 10 to the Accession Treaty. The doctrine of necessity, articulated in the Ibrahim case in 1964, permits departure from constitutional provisions that have become unworkable — it is the legal foundation on which the Republic's institutions have operated for sixty years. Constitutional review is exercised by the Supreme Constitutional Court, restored as a separate court by the 2022 judicial reform.

A constitutional order of two documents and a powerful court

The 1993 Constitution and the separate Charter of Fundamental Rights and Freedoms together form the constitutional order. The Constitutional Court in Brno annuls statutes and also quashes final judgments through the individual constitutional complaint.

A constitutional complaint must be filed within two months of the final decision and requires an attorney; the NALUS database holds the full text of decisions.

The 2006 constitution, revised 2011, over a decentralised 26-province state

The 2006 constitution created a semi-presidential republic with 26 provinces, a Constitutional Court and entrenched provisions that cannot be amended, including the number of presidential terms and the republican form of the state. The 2011 revision moved the presidential election to a single round.

The 2006 text is notable for its entrenched provisions: article 220 forbids any amendment reducing individual rights or altering the number and length of presidential terms, which made the 2015–2016 debate over postponing elections a constitutional rather than merely political dispute. The promised division into 26 provinces was implemented in 2015, creating provincial assemblies with real legislative competence.

The 1953 Grundlov, a unicameral Folketing and a constitutional monarchy

Denmark is a constitutional monarchy governed under the 1953 Constitutional Act. Legislative power is shared between the Monarch and the single-chamber Folketing, and sovereignty may be delegated to international authorities under section 20.

The high bar for amendment means the 1953 text is largely unchanged, so much constitutional development happens through practice and ordinary legislation.

A 1992 constitution, amended in 2010 to remove presidential term limits

The 1992 constitution establishes a presidential republic with a Constitutional Council. The 2010 amendment removed the two-term limit, and the Council reviews legislation on referral rather than on individual petition.

The structure is closely modelled on the French Fifth Republic: a strong executive president, a prime minister, a single-chamber National Assembly and a Constitutional Council that reviews texts before promulgation on referral by the President, the President of the Assembly or a group of deputies. That referral model matters because it means constitutional review is largely abstract and political rather than something an individual litigant triggers. The 2010 revision removed the limit of two presidential terms while introducing an age ceiling, which is the central fact about Djiboutian constitutional practice since. Article 1 declares Islam the state religion while the constitution simultaneously guarantees freedom of religion, and the practical reconciliation is that Islamic law governs personal status while the rest of the legal order is secular and French-derived.

1978 Constitution with final appeal to the Caribbean Court of Justice

The Commonwealth of Dominica Constitution Order 1978 established a parliamentary republic with a President as ceremonial head of state, elected by the House of Assembly, and a Prime Minister who commands its confidence. Chapter I sets out fundamental rights and freedoms, enforceable in the High Court under section 16. Dominica is unusual in the Eastern Caribbean in having accepted the appellate jurisdiction of the Caribbean Court of Justice, so the CCJ, not the Privy Council, is the final court.

Because Dominica accepted the CCJ's appellate jurisdiction in 2015, its rights jurisprudence is developing along a different line from neighbours that remain with the Privy Council. The CCJ has been more willing to depart from older Privy Council authority, particularly on the savings clause that shields pre-independence laws from constitutional challenge, so counsel should check whether a point still rests on a Privy Council decision the CCJ has declined to follow.

2010 Constitution with a Constitutional Court and amparo

The Constitution proclaimed in 2010 and reformed in 2015 created the Tribunal Constitucional, a dedicated constitutional court separate from the Suprema Corte de Justicia, with power to annul laws and to review final judgments through the recurso de revisión. Individual rights are enforced by the acción de amparo, heard at first instance by ordinary courts. The 2015 reform restored presidential re-election for consecutive terms, and a 2024 reform further adjusted the rules.

The most consequential feature is that the Tribunal Constitucional can review final judgments of the Suprema Corte on constitutional grounds, which creates a further layer after what would otherwise be the end of the road. Its decisions are binding on all public powers and are not themselves appealable, and the 60-day amparo window is short and strictly applied.

2008 Constitution recognising rights of nature and buen vivir

Ecuador's 2008 Constitution was the first in the world to grant enforceable rights to nature (derechos de la naturaleza), alongside the Andean concept of sumak kawsay or buen vivir. It creates a Corte Constitucional and a broad set of constitutional guarantees including acción de protección, habeas corpus, habeas data and the acción extraordinaria de protección against judicial decisions.

The rights-of-nature provisions are not merely aspirational: Ecuadorian courts have applied them substantively, most prominently in the Los Cedros cloud-forest judgment of 2021 where the Constitutional Court held that mining concessions violated the rights of the ecosystem itself. The acción extraordinaria de protección is also notable because it permits constitutional challenge to final judgments of the ordinary courts.

A 2014 constitution with a Supreme Constitutional Court that does strike laws down

The 2014 constitution, amended in 2019 to extend presidential terms, establishes a semi-presidential republic. The Supreme Constitutional Court has a genuine record of invalidating legislation, including election laws that dissolved parliament.

Article 2's designation of sharia principles as the principal source of legislation is interpreted by the Supreme Constitutional Court as binding on the legislature but as referring to settled, unambiguous rules rather than to any particular school's detailed holdings, which gives the legislature substantial room. The Court's authority is not theoretical: its 2012 ruling on the parliamentary election law dissolved the elected chamber. The 2019 amendments extended presidential terms and enlarged military jurisdiction, and they were passed by referendum rather than by judicial process. The State Council (Conseil d'Etat) hears administrative claims in a separate hierarchy, which matters because a great deal of practical rights litigation against the state runs there rather than through the ordinary civil courts.

Constitutional Chamber review, and a régimen de excepción since 2022

The Sala de lo Constitucional of the Supreme Court decides amparo, habeas corpus and abstract unconstitutionality claims, the last of which any citizen may bring. Since March 2022 a renewed régimen de excepción has suspended several constitutional guarantees, and any statement of Salvadoran rights that omits it would be misleading.

Under the régimen de excepción administrative detention without charge has been extended and mass hearings are common, so timelines in the ordinary statutes should not be assumed to apply. Verify the current renewal decree before advising on any detention matter.

The 1991 constitution as revised in 2011, in a hispanophone civil-law state

The 1991 constitution, revised by referendum in 2011, created a bicameral parliament, a Constitutional Court and the office of vice-president. Executive power is heavily concentrated and the 2011 revision introduced a nominal two-term limit.

Equatorial Guinea is the only Spanish-speaking state in continental Africa, and its legal vocabulary, court names and civil-law sources are Spanish rather than French even though it sits inside OHADA and CEMAC alongside francophone neighbours — a point that trips up practitioners who assume regional uniformity.

A constitution ratified in 1997 that was never brought into force

The Constitutional Assembly ratified a constitution in 1997. It was never implemented, no national elections have been held, and the National Assembly has not convened since 2002; the state operates by proclamation and decree.

This is the starkest case on the continent of a text existing without an order behind it. The 1997 constitution provides for an elected National Assembly, an independent judiciary and a bill of rights; none of it was implemented. The National Assembly last met in 2002, no national election has ever been held, and a constitutional drafting process announced subsequently produced nothing. Governance runs through presidential proclamations and decrees, and a Special Court operating outside the ordinary judiciary hears cases without appeal and has been used against officials and dissidents. Indefinite national service, formally 18 months under Proclamation 82/1995, has in practice been extended indefinitely and is the subject of a UN Commission of Inquiry finding of crimes against humanity. Every entry for Eritrea is marked research because the published texts do not describe how the state actually operates.

The 1992 Constitution with review by a Supreme Court chamber

Estonia is a parliamentary republic under its 1992 Constitution, with a president chosen by the Riigikogu. Constitutional review is performed by the Constitutional Review Chamber of the Supreme Court.

Estonia's constitutional order is built around digital government, and many rights and duties are exercised through secure electronic identity.

2005 Constitution with executive authority vested in the King and a dual legal system

The 2005 Constitution ended two decades of rule by decree after the 1973 proclamation, but vests executive authority in the King (iNgwenyama), who appoints the Prime Minister and a portion of both chambers. Political parties remain effectively barred from contesting elections, which are conducted on a candidate basis through the tinkhundla system. Chapter III contains a bill of rights.

Eswatini is Africa's last absolute-leaning monarchy under a written constitution, and the tension is internal to the document: Chapter III guarantees expression and association while the tinkhundla electoral structure and royal appointment powers constrain their political exercise. A parallel traditional order — Swazi National Courts, the Ludzidzini council — operates alongside the Roman-Dutch courts.

Ethnic federalism, and constitutional interpretation that is not done by judges

The 1995 FDRE Constitution creates a federation of regional states delineated largely on ethnolinguistic lines, with an Article 39 right of secession. Constitutional interpretation is vested in the House of Federation, advised by the Council of Constitutional Inquiry, rather than in any court.

Ethiopia is the clearest case in Africa of constitutional review being deliberately kept away from the judiciary. Where a case raises a constitutional question, the court refers it to the Council of Constitutional Inquiry, a body of judges and legal experts that investigates and then makes a recommendation to the House of Federation, the upper chamber composed of representatives of the nations and nationalities. The House decides. The design follows from Article 39: if sovereignty rests with the constituent peoples, then the body representing those peoples, not a court of appointed lawyers, resolves what the compact means. The practical consequence is that Ethiopian constitutional doctrine develops slowly and politically, and that a litigant cannot obtain a binding declaration of unconstitutionality from the Federal Supreme Court. The Cassation Division of that court does, however, bind lower courts on questions of ordinary law, which is a 2005 innovation in a system that historically denied precedential force altogether.

2013 Constitution with a justiciable Bill of Rights

A common-law system under the 2013 Constitution, Fiji's fourth since independence. Unlike Australia it has a broad justiciable Bill of Rights, but the document was promulgated by decree rather than by an elected assembly and sets a deliberately high bar for its own amendment.

Chapter 2 contains an unusually detailed Bill of Rights, including socio-economic rights to housing, education and health that most common-law constitutions omit. Two features cut against it. First, amendment requires a three-quarters majority of Parliament, so the text is close to entrenched beyond practical reach. Second, several chapters immunised earlier decrees and their makers from challenge, which limits how far past acts can be litigated. Fiji abolished appeals to the Privy Council, so the Supreme Court of Fiji is final, though it can and does sit with judges from other Commonwealth jurisdictions.

The 2000 Constitution with ex ante review by a parliamentary committee

Finland's consolidated 2000 Constitution vests power in the Eduskunta and a government answerable to it. Constitutionality is checked mainly in advance by the Constitutional Law Committee rather than by a court.

Because review is largely ex ante, the committee's opinions during the legislative process carry great weight and are treated almost as binding.

Semi-presidential Fifth Republic with a priority constitutional question

The 1958 Constitution divides executive power between President and Prime Minister. Since 2008 litigants can raise a question prioritaire de constitutionnalité during ordinary proceedings.

A QPC must be new, serious and applicable to the dispute; the filter is applied by the Cour de cassation or Conseil d'État before referral.

The 1991 constitution, heavily revised, and the 2023 transition

The 1991 constitution established a semi-presidential republic and has been revised repeatedly, including in 2018 and 2023. Following the August 2023 coup the constitutional order was suspended and a transitional charter governed until a new constitution was approved by referendum in November 2024.

Gabon's constitutional history is one of formal continuity interrupted in 2023. The 1991 text was amended so often that presidential term limits were removed and restored more than once, and the 2024 referendum constitution reintroduced a two-term limit while abolishing the office of prime minister. Any statement about Gabonese constitutional law must be dated.

The 1997 Constitution survived the failed 2020 replacement, leaving Jammeh-era provisions in force

The Constitution of the Second Republic 1997 remains in force. A comprehensive draft constitution prepared after the 2016 transition was rejected in the National Assembly in 2020, so the 1997 text — including provisions criticised as concentrating executive power — continues to govern, with the Supreme Court exercising constitutional review.

The 1997 Constitution was adopted under Yahya Jammeh's government and contains a strong presidency. After Jammeh's departure in 2017 a Constitutional Review Commission produced a draft constitution in 2020 introducing presidential term limits, a stronger bill of rights and a reformed judiciary; it failed to secure the required National Assembly majority, and a renewed attempt in 2024 also stalled. The consequence, which the atlas records plainly, is that reform expectations often reported as achieved are not law. Section 4 makes the Constitution supreme. Chapter IV protects fundamental rights, enforceable in the High Court under s.37, with the Supreme Court holding original jurisdiction over interpretation and enforcement under s.127. Sharia applies through the Cadi courts in matters of marriage, divorce and inheritance for Muslims under s.7, which lists Sharia and customary law among the sources of law.

A parliamentary republic completed by the 2017-2018 amendments

The 1995 Constitution was comprehensively amended in 2017, with changes phasing in through 2024. Georgia is now a parliamentary republic in which the President is elected indirectly and executive power rests with a Prime Minister accountable to Parliament. The Constitutional Court sits in Batumi.

The 2017 reform moved Georgia from a mixed system to a parliamentary one: from 2024 the President is chosen by an electoral college rather than by direct vote, and the Prime Minister leads the executive. The Constitutional Court has strong powers, including individual constitutional complaints, and has struck down significant legislation. A distinctive feature is that the Constitution obliges state bodies to take all measures to integrate Georgia into the European Union and NATO. The status of Abkhazia and South Ossetia means the legal order described here does not operate throughout the internationally recognised territory.

The Basic Law, an eternity clause and individual constitutional complaint

The Grundgesetz of 1949 places human dignity first and makes it unamendable. Any person may bring a constitutional complaint to the Federal Constitutional Court after exhausting other remedies.

The Verfassungsbeschwerde has a one-month deadline from the final domestic decision and is the reason German constitutional doctrine is unusually detailed on proportionality.

The 1992 Constitution with entrenched clauses and a Supreme Court monopoly on interpretation

Ghana's Fourth Republican Constitution establishes a hybrid presidential system. The Supreme Court has exclusive original jurisdiction over constitutional interpretation and enforcement, and entrenched provisions can be amended only by referendum requiring 75% approval on a 40% turnout.

The 1992 Constitution ended military rule and has governed uninterrupted since, with peaceful alternations of power that are unusual in the region. Article 2 allows any person to bring an action for a declaration that an act is inconsistent with the Constitution, and article 130 gives the Supreme Court exclusive original jurisdiction over interpretation and enforcement, so constitutional questions arising elsewhere must be referred to it. Chapter 5 rights are justiciable; chapter 6 Directive Principles of State Policy were initially treated as non-justiciable but the Supreme Court in New Patriotic Party v Attorney-General (the 31st December case) and later Ghana Lotto Operators v National Lottery Authority held they are presumptively justiciable, a notable divergence from the Nigerian position. Article 290 entrenches core provisions, requiring a referendum with 75% of votes cast and at least 40% turnout, plus parliamentary passage. The Council of State advises the President, and the National House of Chiefs holds constitutional status over customary matters.

The 1975 Constitution with diffuse review by every court

Greece is a parliamentary republic under the 1975 Constitution. Unusually in Europe, there is no single constitutional court: every judge may refuse to apply an unconstitutional statute, with a Special Highest Court resolving disagreement between the supreme courts.

Because review is diffuse, a constitutional argument belongs in the ordinary pleadings from the outset rather than in a separate application.

1973 Constitution restored in 1983, still appealing to the Privy Council

The Grenada Constitution Order 1973 governs, having been suspended during the 1979 revolution and restored after the 1983 intervention, which makes the continuity of the legal order an unusual feature of Grenadian constitutional law. Grenada is a parliamentary monarchy with a Governor-General and a bicameral Parliament. Referendums in 2016 and 2018 to replace the Privy Council with the Caribbean Court of Justice were both rejected, so the Privy Council remains the final court.

The interruption of constitutional government between 1979 and 1983 left a body of authority on the validity of acts done under the People's Revolutionary Government, and the courts resolved it largely through doctrines of necessity and de facto validity rather than by treating the period as a legal void. Practically, Grenada's retention of the Privy Council means English and Privy Council authority carries more weight here than in neighbouring Dominica or Saint Lucia.

A standalone Constitutional Court with amparo open to anyone

The 1985 Constitution created a Corte de Constitucionalidad sitting outside the ordinary judiciary. Amparo protects against any act, decision or omission of authority, and there is no closed list of protected rights: Article 265 states that amparo lies to prevent or remedy any threat to rights the Constitution or statute guarantees.

Amparo must generally be filed within 30 days of notification of the challenged act, after ordinary remedies are exhausted. Provisional suspension of the act is commonly requested and often decisive. ILO Convention 169 consultation arguments are a recurring and frequently successful ground.

2020 Constitution dissolved after the 2021 coup; a Charte de la Transition governs

The 2020 Constitution was dissolved following the September 2021 coup. A Charte de la Transition vests power in a transitional president and a Conseil National de la Transition. A new constitution has been drafted and put to referendum, so the applicable higher law is in flux.

Guinea's constitutional position cannot honestly be stated as settled. The 2020 Constitution — itself controversial for enabling a third presidential term — was dissolved by the CNRD after the 2021 coup, and governance since has rested on a transitional charter with a shifting timetable. This entry is marked under research for that reason.

1984 Constitution with chronic instability and repeated dissolution of parliament

The Constitution of 1984, substantially revised in 1993 and 1996, establishes a semi-presidential republic. Guinea-Bissau has experienced repeated coups and attempted coups, and parliament has been dissolved and reconstituted several times, so constitutional practice diverges markedly from the text.

Guinea-Bissau has not completed a full presidential term without military interference since independence, and the absence of a dedicated constitutional court leaves review to the Supremo Tribunal de Justiça, whose independence has been repeatedly compromised. A long-promised constitutional revision remains unfinished. The topic is marked under research because the operative constitutional order is unstable rather than merely undocumented.

1980 Constitution, common law, with the CCJ as final court

Guyana is a common-law jurisdiction and the only South American member of CARICOM's Caribbean Court of Justice in its appellate jurisdiction, having abolished appeals to the Privy Council in 1970. The 1980 Constitution is supreme and includes an entrenched bill of rights; constitutional claims go to the High Court and then the Court of Appeal and CCJ.

Guyana's legal system is a hybrid: predominantly English common law after 1917, but with Roman-Dutch law surviving in parts of land law from the Dutch colonial period, which is why conveyancing uses transport and mortgage concepts unfamiliar elsewhere in the Commonwealth Caribbean. The CCJ has decided major Guyanese constitutional cases, including on the validity of a no-confidence motion in 2019 and presidential term limits.

1987 Constitution, amended 2011, under prolonged transitional governance

The Constitution of 1987, adopted after the fall of the Duvalier regime and amended in 2011, provides for a semi-presidential system with a President, a Prime Minister and a bicameral legislature. Since January 2020 Parliament has not functioned for want of elections, and following the assassination of President Moïse in July 2021 governance has run through transitional arrangements, including the Conseil Présidentiel de Transition established in 2024. The Conseil Constitutionnel provided for in the 2011 amendments has never been fully constituted.

Any statement about Haitian law must be read against the institutional reality: with no sitting legislature since 2020, normative acts have taken the form of executive decrees whose constitutional basis is contested, and the absence of a constitutional court leaves no domestic forum to resolve that contest. Practitioners should verify the current status of any instrument before relying on it, because the pace of change and the gaps in official publication are both significant.

The 2023 Fundamental Law and absolute papal sovereignty

Vatican City State is governed by a Fundamental Law promulgated in 2023, replacing the 2000 text. The Pope holds the fullness of legislative, executive and judicial power, delegating administration to the Pontifical Commission and Governorate.

Treating the Holy See and Vatican City State as interchangeable is the most common error: diplomatic relations are with the Holy See, while territorial law belongs to the State.

Constitutional Chamber review and entrenched articles

The 1982 Constitution is enforced through the Sala de lo Constitucional of the Corte Suprema, which hears amparo, habeas corpus and unconstitutionality claims. A set of articles is declared unamendable, and their status was central to the 2009 constitutional crisis and the later ZEDE litigation.

Amparo must generally be filed within 30 days of the act. The 2022 repeal of the ZEDE statute generated ongoing constitutional and investor-treaty disputes, so any advice touching the zones should verify the current litigation position.

The 2011 Fundamental Law and a narrowed constitutional complaint

The Fundamental Law replaced the 1949 constitution in 2012 and has been amended many times. The Constitutional Court still hears individual complaints, but the 2011 reform removed the old actio popularis, so abstract review is now reserved to a defined list of applicants.

A complaint must reach the court that decided the case within 60 days of service, and it is that court which forwards the file, so filing directly in Budapest wastes the deadline.

The 1944 Constitution and an Althingi rooted in 930 AD

Iceland is a parliamentary republic under the 1944 Constitution, with a directly elected President holding a referendum-triggering veto. The Althingi is among the world's oldest parliaments.

The presidential veto is rare but real — its use on media and fisheries laws has twice forced national referendums this century.

The world's longest written constitution with a basic structure doctrine

The 1950 Constitution guarantees fundamental rights enforceable directly in the Supreme Court under Article 32. Kesavananda Bharati (1973) held that amendments cannot destroy the constitution's basic structure.

PIL has made the Supreme Court an unusually active policy forum, and writ petitions are often the fastest route to a remedy against public bodies.

A 1945 Constitution transformed by four post-Suharto amendments

The 1945 Constitution was amended four times between 1999 and 2002, converting a highly centralised presidential system into one with direct presidential elections, a Constitutional Court, regional autonomy and an enforceable rights chapter. The Constitutional Court has since become a genuinely consequential institution, striking down statutory provisions with regularity.

The President is directly elected for a maximum of two five-year terms. The Constitutional Court reviews statutes against the Constitution and can annul provisions. Chapter XA guarantees human rights, though some are subject to statutory limitation. Regional autonomy devolves substantial authority to provinces and regencies, with Aceh, Papua and Yogyakarta holding special status. Constitutional Court decisions are directly operative and frequently change commercial law — the 2021 Job Creation Law ruling is the leading example. Aceh's special autonomy includes Sharia jurisdiction, which does not apply elsewhere in Indonesia.

A republic subordinated to Islamic criteria, with the Leader above the elected branches

The 1979 Constitution, amended in 1989, combines elected institutions with clerical supervision. The Supreme Leader appoints the head of the judiciary and half the Guardian Council, which vets legislation for conformity with Islam and the constitution and vets candidates for elected office.

Article 4 is the organising provision: it requires all civil, penal, financial, economic, administrative and other laws to be based on Islamic criteria, and gives the Guardian Council jurisdiction to judge that question. The Council's twelve members are six clerics appointed by the Leader and six lawyers nominated by the head of the judiciary and approved by parliament. Where the Council and parliament deadlock, the Expediency Council resolves the dispute. This structure means that an Iranian statute can be constitutional in the ordinary sense and still be struck down as un-Islamic, and it is why Iran cannot be described as a civil law system with religious features — the hierarchy runs the other way.

A federal republic with a constitutionally recognised Kurdistan Region

The 2005 Constitution establishes a federal parliamentary republic and recognises the Kurdistan Region as a federal region with its own parliament, government and security forces. The Federal Supreme Court resolves disputes between the federal government and the regions.

The constitution gives the federal government a short list of exclusive powers — foreign affairs, defence, fiscal and monetary policy, citizenship — and provides that in shared areas regional law prevails over federal law where they conflict. That priority rule is unusual and is the source of continuing dispute, particularly over oil and gas, where the Kurdistan Region enacted its own petroleum law and the Federal Supreme Court held in 2022 that it was unconstitutional. Article 140, which set a procedure and deadline for resolving the status of Kirkuk and other disputed territories, has never been implemented. Anyone advising on Iraq must ask which legal order applies before anything else.

Bunreacht na hÉireann, amendable only by referendum

Ireland's 1937 Constitution establishes a parliamentary republic and can be changed only by the people at referendum. The superior courts enforce it, striking down repugnant legislation.

Major social changes — divorce, marriage equality and abortion — each required a referendum rather than ordinary legislation, a defining feature of Irish constitutional life.

Basic Laws in place of a single written constitution

Israel has no single constitutional document. A series of Basic Laws, enacted since 1958, perform constitutional functions, and since the 1995 Bank Mizrahi decision the Supreme Court has asserted the power to review ordinary legislation for compatibility with the Basic Laws on human rights.

The constitutional position is genuinely unusual. The 1950 Harari Resolution deferred a full constitution in favour of chapter-by-chapter Basic Laws, and the project remains incomplete. The 1992 Basic Laws on Human Dignity and Liberty and on Freedom of Occupation contain limitation clauses, and in Bank Mizrahi the Supreme Court held that these gave the Basic Laws superior status and grounded judicial review of Knesset legislation. That power has been the centre of sustained political contention, including the 2023 attempt to restrict it, and the Court struck down an amendment to Basic Law: The Judiciary in January 2024. The High Court of Justice, the Supreme Court sitting in its first-instance administrative capacity, is the forum for constitutional and administrative challenge.

The 1948 Constitution, a bicameral Parliament and referral-based review

Italy is a parliamentary republic under the rigid 1948 Constitution. Both chambers of Parliament have equal powers, and the Constitutional Court decides constitutional questions referred to it by ordinary judges as well as direct state-region disputes.

There is no individual constitutional complaint: a rights argument must be raised in ordinary litigation so the judge can refer the question upward.

2016 Constitution of the Third Republic with a Senate and a Conseil constitutionnel

The Constitution of 8 November 2016 founded the Third Republic, created a Senate and a vice-presidency, and removed the contested nationality-of-both-parents eligibility rule that had fuelled the ivoirité crisis. A 2020 revision followed, and the Conseil constitutionnel rules on elections.

The 2016 Constitution is best read against the ivoirité dispute: the requirement that a presidential candidate's parents both be Ivorian by birth had been used to exclude Alassane Ouattara and contributed to two civil wars. The 2016 text requires only one Ivorian parent. The Cour suprême was subsequently divided into a Cour de cassation, a Conseil d'État and a Cour des comptes, completing the French-style separation.

1962 Constitution with the 2011 Charter of Rights

Jamaica's Constitution came into force at independence in 1962 as a schedule to a UK Order in Council, and it remains the supreme law. The Charter of Fundamental Rights and Freedoms Act 2011 replaced the original Chapter III, widening the guaranteed rights and, importantly, making them enforceable against the state without the old savings-law shield in most cases. Jamaica remains a constitutional monarchy, and the Privy Council in London is still the final court of appeal.

The 2011 Charter matters in practice because it shifted the burden: the state must now justify a limit on a protected right as demonstrably justified in a free and democratic society. A narrow savings clause was retained for certain pre-existing laws, which is why litigation over the death penalty and over colonial-era offences still turns on whether the impugned provision is shielded. Constitutional redress is sought in the Supreme Court, and its decisions run through the Court of Appeal to the Privy Council.

A pacifist constitution never once amended

The 1947 Constitution vests sovereignty in the people, makes the Emperor a symbol of the state and renounces war in Article 9. No amendment has ever been adopted.

Judicial review is real but exercised with marked restraint, so constitutional change in practice happens through reinterpretation and legislation.

A hereditary constitutional monarchy with a strong Crown

The 1952 Constitution establishes a hereditary monarchy with an appointed Senate and elected House of Representatives. The King appoints the Prime Minister, may dissolve parliament, and retains substantial reserved powers. A Constitutional Court was created in 2012.

The 2011 amendments, adopted during regional upheaval, created the Constitutional Court and restricted the use of provisional legislation when parliament is not sitting — previously a very wide executive power. Further amendments in 2016 and 2022 returned some appointment powers to the King and created a National Security Council. The Constitutional Court can review the constitutionality of laws on referral or direct challenge, which is a genuine innovation in a system that previously had no dedicated constitutional jurisdiction, though its caseload remains modest.

A 2022 reform that restored a Constitutional Court and capped the presidency

The 1995 Constitution was amended by referendum in 2022, replacing the Constitutional Council with a full Constitutional Court open to individual complaints and limiting the president to a single seven-year term.

Before 2022 only officials could petition the Constitutional Council, so citizens had no direct route to constitutional review. The new Court accepts individual complaints once ordinary remedies are exhausted, which is the most consequential change in the reform package. The same amendments removed the first president's special status, barred close relatives of the president from senior state office, and reduced presidential appointment powers over regional governors. Rights are listed in Section II and are now directly invocable in a way they previously were not.

The 2010 constitution: devolution to 47 counties and a justiciable bill of rights

The Constitution of 2010 replaced the independence text, creating 47 devolved counties with their own assemblies and revenue share, a Supreme Court, and a bill of rights that binds all state organs and applies horizontally between private parties. It entrenches judicial review of legislation and requires public participation in law-making.

The 2010 constitution is the most consequential single instrument in this batch. It followed the 2007–08 post-election violence and was drafted to disperse power: revenue is constitutionally guaranteed to the counties, the executive cannot appoint judges without the Judicial Service Commission, and the Bill of Rights applies between private parties as well as against the state. Its authority was demonstrated in 2017 when the Supreme Court annulled a presidential election and ordered a fresh poll, and again in the BBI litigation, where the courts held that the basic structure of the constitution limits even the amendment power.

1979 Constitution with custom recognised and climate at the centre

A republic under the 1979 independence Constitution with a justiciable fundamental-rights chapter, an executive President chosen from elected members, and express recognition of Kiribati custom in the application of laws.

The Laws of Kiribati Act 1989 sets the hierarchy of sources and directs that customary law applies in defined matters including land, fishing rights and family, so custom is not merely tolerated but assigned a field of operation. The rights chapter is enforceable in the High Court. Two constitutional peculiarities are worth noting: the President must be an elected member of the Maneaba ni Maungatabu and is chosen by national vote from a shortlist the Maneaba nominates, and the Banabans, displaced to Fiji by phosphate mining, retain a constitutionally acknowledged position including a reserved seat. Climate change has become a constitutional-scale question: the state has purchased land in Fiji and pursued a migration-with-dignity policy, both premised on the possibility that habitability, not sovereignty, fails first.

The Gulf's strongest parliament, repeatedly suspended

The 1962 Constitution creates the most powerful elected legislature in the Gulf, with real power over legislation and ministers. The Emir has dissolved it repeatedly, and suspended it in 2024.

The National Assembly's powers of interpellation and no-confidence in individual ministers are real and have been used, which distinguishes Kuwait sharply from its neighbours and explains the recurring cycle of confrontation and dissolution. In May 2024 the Emir dissolved the Assembly and suspended several constitutional articles for up to four years, which is the most significant constitutional event in decades and means any description of Kuwait as a functioning parliamentary emirate needs to be dated. The Constitutional Court has a record of genuine independence, including annulling elections and striking down legislation.

A 2021 constitution that swung back to presidential rule

After the 2020 unrest, a referendum in 2021 adopted a new constitution replacing the parliamentary system of 2010 with a strong presidency and a traditional Kurultai advisory assembly.

The 2021 text concentrated executive power, allowed the president two five-year terms, cut parliament from 120 to 90 seats and gave the president authority over judicial appointments and referendums. It also introduced a controversial provision permitting restriction of activities contradicting moral values and public consciousness, criticised as an open-ended limit on expression. The Constitutional Court accepts individual complaints, and Kyrgyzstan remains party to the ICCPR with its individual-complaint protocol, so treaty-body findings continue to be a live avenue.

A one-party socialist state, constitution amended in 2015

The 1991 Constitution, amended in 2003 and 2015, establishes the Lao People's Revolutionary Party as the leading nucleus of the political system. The National Assembly is the supreme organ of state power and elects the President. There is no constitutional court; the National Assembly itself interprets the Constitution and laws.

The Lao People's Revolutionary Party is constitutionally the leading force in the political system. The National Assembly is the highest organ of state power and interprets the Constitution. The 2015 amendment created Provincial People's Assemblies and strengthened local government. Rights are granted subject to law, and there is no judicial mechanism to enforce them against legislation. Because the National Assembly interprets the Constitution, there is no route to challenge a statute as unconstitutional in court. The Official Gazette became the authoritative publication for legislation under the 2012 Law on Making Legislation.

The restored 1922 Satversme and an active Constitutional Court

Latvia's 1922 Constitution was restored after independence, with the Saeima electing the President. The Constitutional Court (Satversmes tiesa) reviews legislation, including on individual complaint.

The individual-complaint route to the Constitutional Court makes it an active guardian of rights, unusually accessible in the region.

Confessional power-sharing under the 1926 Constitution and the Taif Agreement

The 1926 Constitution, amended in 1990 to incorporate the Taif Agreement, distributes the presidency, premiership and speakership among religious communities and divides parliamentary seats equally between Christians and Muslims.

Taif transferred executive power from the President to the Council of Ministers collectively and equalised Christian and Muslim parliamentary representation, replacing the earlier six-to-five ratio. The Constitution's preamble commits to abolishing political confessionalism as a national goal while the operative text entrenches it, a tension that has never been resolved. The Constitutional Council may review laws on referral by defined officeholders — not by individuals — and has periodically been unable to function for want of appointments. Prolonged presidential and governmental vacuums are a recurring feature rather than an aberration.

1993 Constitution, a constitutional monarchy, and a Court of Appeal apex

The 1993 Constitution restored civilian rule and establishes the King as a constitutional monarch who reigns but does not govern. Chapter II contains fundamental human rights; Chapter III sets non-justiciable principles of state policy. The Court of Appeal is the apex, above the High Court which hears constitutional matters at first instance.

Lesotho's constitutional history since 1993 has been marked by repeated coalition instability and a long-running reform process addressing the security services and the judiciary. The distinction between the justiciable Chapter II rights and the declaratory Chapter III principles is the practical starting point for any rights claim.

An American-derived constitutional order: the 1986 Constitution and a Supreme Court on the US model

Liberia was never a European colony. The 1986 Constitution, adopted after the 1980 coup, establishes a US-style separation of powers with a bicameral Legislature and a Supreme Court of five justices exercising judicial review. Article 27 restricts land ownership and citizenship to persons of Negro descent.

Liberia's legal order descends from nineteenth-century American settler law rather than British colonial administration, and the vocabulary and structure reflect it: a President and Vice-President, a Senate and House of Representatives, and a Supreme Court with a Chief Justice and four Associate Justices exercising review of legislative and executive action. The 1986 Constitution replaced the 1847 text after the Doe coup and survived two civil wars, with the 2003 Comprehensive Peace Agreement operating alongside it during the transition. Article 27(b) limits citizenship, and therefore land ownership under article 22, to persons of Negro descent — an unusual and much-debated provision that survived a 2020 referendum attempt at reform. Article 65 vests judicial power in the Supreme Court and subordinate courts, and the Court's opinions are the principal source of constitutional doctrine. Customary law is recognised for the indigenous majority through a parallel system of tribal courts, and the historical distinction between statutory and customary jurisdictions remains a live equality question.

No settled constitution: a 2011 interim declaration and rival authorities

Libya has operated under the 2011 Interim Constitutional Declaration since Gaddafi's fall. A 2017 draft constitution was never adopted by referendum, and rival executives and legislatures claim authority.

Any description of Libyan constitutional law must begin with the fact that there is no ratified constitution and no single authority whose enactments are uniformly recognised. The 2011 Interim Declaration remains the nominal framework, amended repeatedly, and the 2017 draft prepared by the Constitution Drafting Assembly never went to referendum. The Supreme Court in Tripoli has issued rulings on the legitimacy of institutions that were not accepted by all parties, which is the clearest illustration of the problem: a judgment on the books is not necessarily an operative rule. Elections planned since 2021 have not been held. For practical purposes, the question of which authority's law applies is territorial and must be established before any substantive analysis.

A dual monarchy: an unusually strong prince alongside direct democracy

Liechtenstein is a constitutional hereditary monarchy in which power is shared between the Reigning Prince and the people. The 2003 constitutional reform confirmed the Prince's exceptionally strong position — including a veto on legislation and the power to dismiss the government — while also giving citizens the right to vote on abolishing the monarchy.

The 2003 reform is internationally unusual in strengthening monarchical power and direct democracy at the same time. Rights protection in practice runs through the Staatsgerichtshof and the ECHR, to which Liechtenstein is a party.

A semi-presidential 1992 Constitution and a strong Constitutional Court

Lithuania's 1992 Constitution, adopted by referendum, creates a semi-presidential republic with a directly elected President. The Constitutional Court rules on the constitutionality of laws and official acts.

The Constitutional Court's doctrine of the 'constitution as a coherent whole' gives it broad interpretive reach over Lithuanian law.

A newly revised constitution in force since 2023, in a constitutional monarchy

Luxembourg is a constitutional monarchy whose thoroughly revised constitution entered into force on 1 July 2023, modernising the 1868 text across four successive revisions. Constitutional review is exercised by the Constitutional Court, which decides questions of the conformity of statutes with the constitution referred to it by other courts.

Constitutional questions reach the Constitutional Court by referral from the court hearing a case, not by direct individual complaint. The 2023 revision reorganised the text into distinct chapters on the state, rights, and institutions.

2010 Constitution of the Fourth Republic with a Haute Cour Constitutionnelle

The 2010 Constitution established the Fourth Republic after the 2009 political crisis, creating a semi-presidential system. The Haute Cour Constitutionnelle reviews constitutionality, validates elections and has repeatedly arbitrated political transitions, including confirming the 2023 result and the 2025 change of government.

Madagascar is not an OHADA member, which distinguishes its commercial law from the francophone mainland, but its public law is thoroughly French in design: a semi-presidential executive, a Conseil d'État for administrative matters and a constitutional court that doubles as the electoral authority.

1994 Constitution with judicial review and a Constitutional Court sitting in panels

The 1994 Constitution ended one-party rule and contains a justiciable Chapter IV Bill of Rights. Constitutional matters are heard by the High Court sitting as a Constitutional Court in a panel of three judges, certified by the Chief Justice, with appeal to the Supreme Court of Appeal. The 2020 annulment of the 2019 presidential election in Mutharika v Chilima is the leading demonstration of judicial independence.

The certification mechanism, under which the Chief Justice constitutes a three-judge panel for constitutional questions, gives Malawi a Constitutional Court in function without a separate institution. The 2020 election judgment, upheld on appeal, made the mechanism internationally visible.

A federal constitutional monarchy with parallel civil and Sharia jurisdiction

The Federal Constitution of 1957 establishes a federation of thirteen states with a rotating elective monarch, the Yang di-Pertuan Agong. Article 121(1A) removes from the civil courts jurisdiction over matters within the Sharia courts' competence, creating a genuine and much-litigated boundary problem, particularly in conversion and custody cases.

The Yang di-Pertuan Agong is elected for five years from among the nine Malay Rulers. Article 121(1A) excludes civil court jurisdiction over matters within Sharia court jurisdiction. Part II guarantees fundamental liberties, subject to substantial statutory restriction powers. Article 153 provides for the special position of the Malays and natives of Sabah and Sarawak. The civil/Sharia jurisdictional boundary is the most consequential constitutional issue in practice — it determines forum in family and conversion disputes. Sabah and Sarawak hold distinct constitutional protections under the Malaysia Agreement 1963, including immigration autonomy.

2008 Constitution requires all citizens to be Sunni Muslim

The 2008 Constitution establishes a presidential system with separated powers and a bill of rights, while Article 9(d) provides that a non-Muslim may not become a citizen and Islam is the basis of all law.

Chapter 2 rights are enforceable and the Supreme Court exercises constitutional review, but Article 10 requires that no law contrary to a tenet of Islam be enacted, so rights operate within that limit. The 2008 text ended a long period of one-man rule and created independent commissions, though political interference in judicial appointments has been a recurring criticism from the ICJ and UN special procedures.

2023 Constitution adopted by referendum under a transitional military government

A new Constitution was approved by referendum in June 2023 and promulgated in July 2023, replacing the 1992 text, having been drafted under the transitional authorities installed after the 2020 and 2021 coups. It strengthens the presidency and creates a Cour constitutionnelle. Its consolidation is ongoing.

Mali's 2023 Constitution was adopted while the state was governed by a military-led transition and while significant northern territory lay outside government control, with the referendum not held in some areas. Describing it as settled constitutional law would overstate the position, which is why this entry is marked under research even though the text itself is published and in force.

A 1964 Constitution, entrenched rights and a mixed legal tradition

Malta is a parliamentary republic under the 1964 Constitution, which is the supreme law and entrenches fundamental rights. The system mixes a Continental civil code with English-derived public law, procedure and commercial statutes.

Because both English and Maltese are official, statutes exist in both languages; the Maltese text prevails in case of conflict for most modern laws.

1979 Constitution blending a Westminster executive with chiefly authority

A republic under the 1979 Constitution with a President elected by and from the Nitijela, a justiciable bill of rights, and a Council of Iroij that reviews legislation touching custom and land.

The Constitution combines a parliamentary executive with entrenched traditional authority. The Nitijela of 33 members elects the President from among its own membership, so the executive is drawn from and answerable to the legislature. Article III establishes the Council of Iroij, twelve traditional leaders who may express an opinion on any bill affecting customary law, land tenure or traditional practice; the opinion does not bind the Nitijela but it is a formal constitutional stage. Article VI creates the Traditional Rights Court, a court of record with jurisdiction over customary title and land, which no other Pacific constitution replicates in quite this form. The Compact of Free Association, effective 1986 and renewed in 2024 through 2043, leaves defence and security to the United States while preserving Marshallese sovereignty over internal affairs.

1991 Constitution declaring an Islamic republic with sharia as the source of law

The Constitution of 20 July 1991, revised in 2006, 2012 and 2017, establishes an Islamic republic in which Islam is the religion of the state and people and sharia is the source of law. The 2017 revision abolished the Senate, replacing it with regional councils.

Mauritania is one of a small number of states whose constitution designates sharia as the source of legislation rather than merely a source, which conditions the interpretation of every other code. The 2017 abolition of the Senate by referendum, after the Senate itself had rejected the amendment, was constitutionally contentious and remains the principal domestic critique of the current settlement.

1968 Constitution, a Supreme Court, and a retained appeal to the Privy Council

The 1968 Constitution is the supreme law, with Chapter II fundamental rights enforceable in the Supreme Court. Mauritius is a parliamentary republic with a ceremonial President. Uniquely among African states alongside Seychelles, final appeals in many matters still lie to the Judicial Committee of the Privy Council in London.

The retained Privy Council appeal is the defining institutional feature: Mauritian constitutional and commercial jurisprudence is developed partly in London, which gives the case law an unusual authority in the region and links it directly to Commonwealth doctrine.

Amparo is the master remedy against any act of authority

Rights are enforced through the juicio de amparo, available against laws, judicial decisions, administrative acts and omissions. The 2011 reform to Article 1 gave ratified human-rights treaties constitutional rank and requires every authority to prefer the interpretation most favourable to the person.

Deadlines are short and strictly applied: 15 working days for most amparo claims, eight years for a final criminal sentence, and 30 days where the claim is against a general norm. Filing is possible through the federal judiciary's electronic portal with an e-signature.

1979 federal Constitution over four states, with custom constitutionally shielded

A federation of Chuuk, Kosrae, Pohnpei and Yap under the 1979 Constitution. National powers are enumerated, residual power lies with the states, and tradition is protected against inconsistent legislation.

The Constitution enumerates national powers, chiefly foreign affairs, defence, immigration, citizenship, banking and interstate commerce, and leaves everything else to the states, so land, most crime and most civil matters are state questions and differ materially between Chuuk, Kosrae, Pohnpei and Yap. Article IV contains a justiciable declaration of rights drafted on United States lines, and article V protects traditional rights, expressly allowing a statute to be held invalid if it fails to protect tradition and permitting states to give formal roles to traditional leaders, which Yap and Pohnpei have done. The Compact of Free Association, effective 1986, amended in 2003 and renewed in 2023 through 2043, provides US funding and defence responsibility while preserving sovereignty. Anyone researching FSM law must identify the relevant state at the outset, because a national answer is often not the operative one.

A 1994 constitution with EU integration written in

The Constitution of 1994 declares a parliamentary republic and, since the 2023 amendment, records the irreversibility of the European course. The Constitutional Court has no direct individual complaint, but the exception of unconstitutionality may be raised in any pending case.

Since 2016 a party may ask the trial judge to refer directly, and a refusal to refer is itself reviewable, which made the exception a far more usable route than before.

A constitutional monarchy under the 1962 Constitution, with a shared legislature

Monaco is a hereditary constitutional monarchy governed by the Constitution of 17 December 1962, revised in 2002. The Sovereign Prince holds executive authority and shares legislative power with the elected National Council, while judicial power is delegated by the Prince to independent courts.

The 2002 revision modernised the succession rules and the balance between the Prince and the National Council. The Tribunal Suprême is unusual in combining constitutional and administrative jurisdiction.

A semi-presidential republic with a dedicated constitutional court

The 1992 Constitution created a parliamentary republic with a directly elected president. The Constitutional Court, called the Tsets, reviews legislation and its findings bind the State Great Khural once confirmed.

The 2019 amendments strengthened the prime minister's control over cabinet appointments and limited the president to a single six-year term. The 2023 amendment enlarged parliament to 126 seats and introduced a partly proportional system. Chapter Two guarantees a substantial list of rights, and the Tsets can be petitioned by citizens directly, which makes it unusually accessible for the region. A Tsets finding of unconstitutionality is referred to parliament, and if parliament rejects it the court may then rule finally.

The 2007 Constitution, a single-chamber Parliament and a Constitutional Court

Montenegro is a parliamentary republic under the 2007 Constitution, adopted after independence. The Constitutional Court reviews the constitutionality of laws and decides constitutional complaints, and EU alignment drives continuing reform.

Judicial and prosecutorial appointments require qualified parliamentary majorities, which has caused prolonged institutional vacancies.

A 2011 constitution that constrains but preserves the monarchy

The 2011 constitution, adopted after the February 20 protests, transferred significant powers to an elected government while retaining the King's religious authority as Commander of the Faithful and his control over strategic sectors.

The 2011 text obliges the King to appoint the head of government from the party that wins the most seats, which converted a discretionary appointment into a constrained one and is the most concrete change in the document. Two spheres remain reserved: religion, through the King's status as Commander of the Faithful, and the strategic domains of defence and foreign policy exercised through the Council of Ministers. Amazigh was recognised as an official language alongside Arabic, with an organic law following in 2019. Constitutional review is concentrated and mostly a priori, so litigants cannot generally raise constitutionality collaterally in ordinary proceedings, which limits the constitution's practical role in private disputes.

2004 Constitution with a Conselho Constitucional and decentralisation since 2018

The 2004 Constitution, amended in 2018, establishes a semi-presidential system and vests constitutional review in the Conselho Constitucional rather than a court within the ordinary hierarchy. The 2018 amendments introduced elected provincial governors as part of the peace process with Renamo.

The Conselho Constitucional is modelled on the French Conseil constitutionnel rather than on a supreme court with constitutional jurisdiction, and it also validates election results — which has made it a central institution in every disputed Mozambican election, including 2024.

2008 Constitution suspended under emergency rule since February 2021

The 2008 Constitution reserved a quarter of legislative seats for the military and gave it an effective amendment veto. Since the coup of 1 February 2021 the State Administration Council has governed under a declared state of emergency, and constitutional guarantees are not being enforced.

Section 436 required more than 75 percent of the legislature to amend core provisions, which the 25 percent military bloc alone could block. Chapter VIII listed fundamental rights subject to laws enacted for security and public order. The Constitutional Tribunal existed but never checked military prerogatives. Since 2021 the Council has ruled by decree, section 505A has criminalised comment likely to cause fear or disrupt state employees, and closed-court proceedings inside prisons have been widely reported. Anyone advising on Myanmar should treat the constitutional text as a description of a suspended framework rather than of current practice.

1990 Constitution with entrenched Chapter 3 rights and a Supreme Court apex

Namibia's 1990 Constitution followed UN-supervised independence and entrenches Chapter 3 fundamental rights, several of which cannot be diminished by amendment at all. Article 66 gives customary law and the common law equal force so far as they do not conflict with the Constitution. The Supreme Court is final; the High Court hears constitutional matters at first instance.

Article 131 is unusual: it makes the Chapter 3 rights unamendable in a way that reduces their protection, so the Constitution places substantive limits on the constituent power itself. The Supreme Court has used Chapter 3 actively, including in Digashu and Seiler-Lilles (2023) recognising same-sex marriages concluded abroad.

1968 Constitution; appeals to Australia's High Court ended in 2018

A republic under the 1968 independence Constitution with an enforceable fundamental-rights chapter and a President chosen by Parliament. Nauru terminated its appellate link to the High Court of Australia in 2018.

The 1968 Constitution is deliberately entrenched and has resisted amendment; a comprehensive reform package was rejected by referendum in 2010. The most consequential recent constitutional act was the termination in 2018 of the agreement allowing appeals from the Supreme Court of Nauru to the High Court of Australia, replaced by a domestic Court of Appeal. The change was contested because it removed an external appellate check at a time of disputes involving opposition politicians and the judiciary, and it means Nauru's final court is now wholly domestic. The Custom and Adopted Laws Act preserves Nauruan custom and institutions such as the Nauru Lands Committee.

2015 Constitution made Nepal a secular federal republic

The 2015 Constitution replaced a unitary Hindu monarchy with a secular federal republic of seven provinces. It contains an unusually long list of enforceable fundamental rights and a Constitutional Bench within the Supreme Court.

Article 133 gives the Supreme Court power to void laws inconsistent with the Constitution, and Nepal's public interest litigation record is notably active — the Supreme Court has ordered recognition of a third gender category and directed reform in several areas. The Constitutional Bench hears federalism and election disputes. Citizenship provisions, particularly for children of Nepali mothers and foreign fathers, remain contested and litigated.

A constitution the courts may not enforce against statute — rights run through treaties instead

The Grondwet organises the state and lists fundamental rights, but Article 120 forbids the courts from testing Acts of Parliament and treaties against it. The practical consequence is that rights litigation is conducted under directly effective treaty law — above all the ECHR — which Article 94 requires courts to apply in preference to conflicting statute.

Because there is no constitutional court and no individual constitutional complaint, a rights argument is framed as a treaty-conformity argument inside ordinary proceedings. A long-running debate on relaxing Article 120 has not changed the rule.

Uncodified constitution; Bill of Rights Act 1990 s. 4 bars invalidation

An uncodified constitution: no single supreme document, parliamentary sovereignty, and a Bill of Rights that courts cannot use to strike down legislation. The Treaty of Waitangi is a distinct and central constitutional element.

New Zealand has no entrenched written constitution and no power of judicial invalidation. Section 4 of the Bill of Rights Act is explicit: no court may hold any enactment invalid or refuse to apply it by reason of inconsistency with the Act. Instead s. 6 requires legislation to be read consistently with rights where possible, and s. 7 requires the Attorney-General to report to Parliament on any bill that appears inconsistent — a political rather than judicial safeguard. The Supreme Court has declared inconsistency in cases such as Taylor without affecting the statute's validity. The Treaty of Waitangi is not directly enforceable of its own force, but its principles are referenced in many statutes and give the Waitangi Tribunal its jurisdiction.

Constitutional Chamber amparo, with contested independence

The 1987 Constitution provides amparo, habeas corpus and habeas data through the Sala de lo Constitucional of the Corte Suprema. Since 2018 the OAS, the UN human-rights system and a UN Group of Human Rights Experts have documented the dismantling of independent checks, including mass deprivation of nationality, so the written guarantees and their practical availability diverge sharply.

Amparo must be filed within 30 days, but the Sala has in practice not ruled against the executive in politically sensitive matters since 2018. Advise clients that domestic remedies may be exhausted quickly for the purpose of an Inter-American petition.

2010 Constitution suspended after the July 2023 coup; governance by ordinance

The 2010 Constitution of the Seventh Republic was suspended following the July 2023 coup that removed President Bazoum. The Conseil National pour la Sauvegarde de la Patrie governs by ordinance under a transitional charter, and the Cour constitutionnelle was dissolved.

Niger's 2023 coup interrupted what had been the country's first transfer of power between elected presidents. The suspension of the Constitution, dissolution of the Cour constitutionnelle and detention of the deposed president mean the applicable higher law is a transitional ordinance rather than the 2010 text, and this entry is marked under research accordingly.

Federal supremacy under the 1999 Constitution, with twelve states applying Sharia penal codes

The Constitution of the Federal Republic of Nigeria 1999 (as amended) is supreme; any inconsistent law is void to the extent of the inconsistency. Legislative power is split between the Exclusive, Concurrent and Residual lists. Chapter II socio-economic objectives are expressly non-justiciable, while Chapter IV fundamental rights are enforceable in the High Courts.

Nigeria's constitutional order is federal, presidential and unusually litigated. Section 1(3) makes the Constitution supreme. Section 4 divides competence: the National Assembly legislates on the Exclusive List, both tiers on the Concurrent List, and states hold the residue. Section 6(6)(c) renders the Chapter II Fundamental Objectives non-justiciable, a provision that has repeatedly defeated socio-economic claims, whereas Chapter IV rights are enforced through the Fundamental Rights (Enforcement Procedure) Rules 2009. Section 275 authorises Sharia Courts of Appeal in states that want them, and from 2000 twelve northern states (Zamfara first, then Kano, Katsina, Sokoto, Kebbi, Niger, Jigawa, Bauchi, Borno, Yobe, Kaduna and Gombe) enacted Sharia Penal Codes. Their constitutionality has never been squarely resolved by the Supreme Court, which is the single most important caveat for any account of Nigerian criminal law.

A constitution subordinate to Party rule, unverifiable in practice

The Socialist Constitution vests supreme power in the Supreme People's Assembly, but the Workers' Party of Korea holds actual authority. No independent verification of constitutional practice is possible.

The published constitution guarantees rights including freedom of speech, assembly and religion, and the 2019 amendment restructured the office of head of state. UN Commission of Inquiry findings describe systematic and widespread violations bearing no relation to these texts, including political prison camps and denial of any independent judicial remedy. There is no accessible official gazette, no published case law and no bar independent of the state, so this entry deliberately reports the documentary framework and its unverifiability rather than describing a functioning legal order.

The 1991 Constitution with Ohrid power-sharing and the Badinter majority

North Macedonia is a parliamentary republic under the 1991 Constitution, amended after the 2001 Ohrid Framework Agreement. Laws touching culture, language and identity require a double majority including a majority of minority-community members.

Constitutional amendments have twice been driven by external agreements, the Ohrid Agreement and the Prespa Agreement on the country's name.

The 1814 Grunnlov, a unicameral Storting and judge-made review

Norway is governed under the 1814 Constitution, one of the world's oldest. The Storting has sat as a single chamber since 2009, and the courts have long claimed a power to review statutes for constitutionality.

Norway is outside the EU, so EU-derived rules enter Norwegian law through the EEA Agreement rather than directly.

A 2021 Basic Law that finally settled the succession

The Basic Law of 1996 was replaced in 2021 by a new statute that created the office of Crown Prince and codified the succession for the first time.

The 2021 Basic Law matters because Oman's previous succession mechanism was opaque, relying on a sealed letter from the Sultan and family consensus, and Sultan Haitham's accession in 2020 exposed how fragile that was. The new law names the eldest son of the Sultan as Crown Prince, which is a structural constitutional change rather than a restatement. It also strengthened the language on rights and on the Council of Oman, whose elected Shura Council has limited legislative powers alongside the appointed State Council. Sharia is named as the basis of legislation.

1973 Constitution with an Islamic repugnancy check on legislation

The 1973 Constitution creates a federal parliamentary republic. The Federal Shariat Court may strike down laws repugnant to Islam, and the Supreme Court exercises broad original jurisdiction under Article 184(3).

The Eighteenth Amendment devolved substantial subjects — including labour, health and education — to the provinces, so a great deal of operative law is provincial rather than federal, and assuming a single national rule is a common error. Article 184(3) suo motu jurisdiction has been used expansively and was curtailed by the 2023 Practice and Procedure Act. Article 8 voids laws inconsistent with fundamental rights, and Article 199 gives High Courts writ jurisdiction.

1981 Constitution with a nuclear-free clause needing a 75% referendum

A republic under the 1981 Constitution with a directly elected President, a bicameral Olbiil Era Kelulau, a Council of Chiefs, and an entrenched nuclear-free provision.

Palau has a US-style separation of powers: a directly elected President and Vice-President, a bicameral legislature comprising a Senate and a House of Delegates with one delegate per state, and an independent judiciary. Article VIII gives the Council of Chiefs a formal advisory role to the President on matters of traditional law and custom, so chiefly authority is constitutionally recognised rather than merely social. The most consequential provision is article XIII, section 6, which bars nuclear, chemical, biological and radioactive materials from Palau unless approved by a three-quarters majority in referendum; this clause delayed approval of the Compact of Free Association through the 1980s and required repeated votes before the Compact took effect on 1 October 1994. The Compact was renewed in 2023, extending economic assistance while the United States retains defence responsibility.

A Basic Law, a legislature that has not sat since 2007, and rule by decree

The 2003 Basic Law as amended serves as the constitutional instrument for the Palestinian Authority. The Legislative Council has not convened since 2007 and was dissolved in 2018, so primary legislation is made by presidential decree.

Article 43 was drafted as an emergency provision for periods between sessions; since 2007 it has become the ordinary mode of legislation, and hundreds of decree-laws now form much of the statute book. The Supreme Constitutional Court, established in 2006 but only constituted in 2016, ruled in 2018 that the Legislative Council should be dissolved — a decision itself criticised as consolidating executive power. Gaza's administration has issued its own legislation since 2007, so on many subjects there are now two divergent bodies of Palestinian law. Any statement about Palestinian law as a single body needs to specify which territory and which period.

Open standing to challenge any statute

Panama's guarantee jurisdiction is concentrated in the Supreme Court sitting in plenary. Any person may file a demanda de inconstitucionalidad against any law, decree or act without showing personal injury — one of the widest standing rules in the hemisphere — and a ruling voids the norm for everyone, but only prospectively.

Amparo must generally be filed with a court of higher rank than the official whose order is challenged, which decides where the case starts. There is no filing fee for constitutional actions.

1975 Constitution making custom part of the underlying law

An autochthonous 1975 Constitution with a justiciable Basic Rights chapter, National Goals and Directive Principles, and — unusually — a formal instruction that custom forms part of the country's underlying law.

Two things make PNG's constitutional law distinctive. First, schedule 2.1 adopts custom as part of the underlying law, and the Underlying Law Act 2000 directs courts to apply custom in preference to English common law — a reversal of the usual colonial hierarchy, though in practice the courts have applied it unevenly. Second, the Constitution is heavily entrenched and detailed, creating institutions such as the Ombudsman Commission and a Leadership Code that has removed serving ministers from office. Bougainville's autonomy arrangements, arising from the peace agreement after the civil conflict, include a referendum on independence whose result requires ratification by the national Parliament.

1992 Constitution with bilingual official languages

The 1992 Constitution followed the end of the Stroessner dictatorship and establishes a unitary presidential republic. Spanish and Guaraní are both official languages, a distinctive recognition of an indigenous language spoken by most of the population. The Corte Suprema's Sala Constitucional rules on unconstitutionality actions, and amparo is available for urgent rights protection.

Constitutional review is concentrated in the Sala Constitucional of the Supreme Court, which may declare a norm inapplicable to the case or, in an action of unconstitutionality, annul it. The bilingual guarantee is not symbolic: Guaraní has status in education and official communication, and the Ley de Lenguas of 2010 built institutional machinery around it.

1993 Constitution with a Tribunal Constitucional and amparo

Peru's 1993 Constitution establishes a unitary republic with a Tribunal Constitucional that hears final appeals in constitutional actions and rules on the constitutionality of statutes. The Código Procesal Constitucional consolidates amparo, habeas corpus, habeas data and the acción de cumplimiento. Constitutional processes take priority over ordinary litigation.

Peru consolidated all constitutional remedies into a single procedural code, first in 2004 and then replaced by Ley 31307 in 2021, which is unusual and makes the procedural rules for amparo and habeas corpus easy to locate in one instrument. The Tribunal Constitucional also issues binding precedents that lower courts must follow, giving its rulings force beyond the individual case.

1987 Constitution with judicial review and a 60/40 foreign equity ceiling

The 1987 Constitution, adopted after the Marcos era, gives the Supreme Court expansive review powers including over grave abuse of discretion by any branch. Article XII reserves at least 60 percent Filipino ownership in land, utilities and natural resources.

The 1987 charter reacted to dictatorship by limiting presidential emergency powers: martial law is capped at sixty days, requires congressional review and is reviewable by the Supreme Court. Rights protections are extensive, and the Court developed the writs of amparo and habeas data to address enforced disappearances. The nationality restrictions in Article XII have shaped foreign investment for decades; RA 11659 narrowed the definition of public utility in 2022 so that telecommunications, shipping, airlines, railways and expressways fell outside the 40 percent cap, which is the most significant liberalisation without amending the Constitution itself.

A 1997 constitution with a contested constitutional tribunal

The Constitution of 1997 is supreme law and provides an individual constitutional complaint. Since 2015 the composition of the Constitutional Tribunal has been disputed, and the ECtHR held in Xero Flor v. Poland that a panel including an improperly elected judge is not a tribunal established by law.

A constitutional complaint attacks the norm applied in your case, not the judgment itself, and must be lodged by an advocate or radca prawny within three months of a final decision.

The 1976 Constitution, a semi-presidential republic and strong abstract review

Portugal is a semi-presidential republic under the 1976 Constitution, which pairs a directly elected President with a Government answerable to the Assembly of the Republic. The Constitutional Court reviews laws both before promulgation and after they take effect.

Preventive review makes the President a real actor in the legislative process, and successful references frequently reshape bills before enactment.

A 2004 permanent constitution with a hereditary Emir

The 2004 Constitution establishes a hereditary emirate in which the Emir holds executive authority. Islamic law is named as a principal source of legislation.

The 2004 Constitution replaced the provisional basic law and formalised the separation of powers on paper while leaving executive authority with the Emir, who appoints the Prime Minister and can rule by decree when the Shura Council is not sitting. The first Shura Council elections in 2021 filled thirty of forty-five seats, and the constitutional amendment approved by referendum in 2024 reverted the Council to full appointment, which is a significant retreat from the 2021 position and is often missed in material written between those dates. Article 1 names sharia as a principal source of legislation rather than the sole source.

The 2015 constitution, which removed the two-term limit

The constitution approved by referendum in October 2015 replaced the 2002 text, raised the presidential age limit and reset term limits, permitting a further candidacy. It creates a Constitutional Court and a bicameral parliament.

The 2015 referendum is the defining event of contemporary Congolese constitutional law: it was contested precisely because its practical effect was to permit an additional presidential candidacy, and the resulting litigation shaped the Constitutional Court's early jurisprudence.

A 1991 constitution revised in 2003 with mandatory review of laws

The Constitution of 1991, revised in 2003, established a semi-presidential republic. The Constitutional Court reviews statutes before promulgation on referral by defined authorities, and reviews them after entry into force only through an exception raised in pending litigation.

The exception must be raised before the trial court, which suspends nothing but refers the point to Bucharest, so it is a slow remedy used strategically rather than urgently.

The 1993 constitution as amended in 2020, with treaty supremacy curtailed

The Constitution of 1993 was substantially amended in 2020, resetting presidential terms and inserting Article 79 wording allowing non-execution of international bodies' decisions found contrary to the constitution. The Constitutional Court retains an individual complaint after exhaustion of remedies.

Since 2020 a complaint is admissible only after cassation is exhausted, which lengthened the route considerably and made the timing of the four-month filing window the main procedural trap.

The 2003 constitution as revised in 2015, with power-sharing guarantees

The 2003 constitution, substantially revised by referendum in 2015, entrenches provisions against genocide ideology, requires that no single party hold more than half the cabinet posts, and reserves at least 30% of decision-making positions for women. The 2015 revision reset presidential terms and shortened them to five years from 2024.

Rwanda's constitution is shaped throughout by the 1994 genocide: it constitutionalises power-sharing across parties, entrenches gender quotas that have made Rwanda's parliament the most female in the world, and criminalises genocide ideology and denial. The 2015 revision, approved with an overwhelming reported majority, permitted the incumbent to stand again while reducing future terms.

The Caribbean's only federation, with a right of secession for Nevis

The Saint Christopher and Nevis Constitution Order 1983 created the only federal state in the Caribbean. Nevis has its own Island Assembly, Premier and Nevis Island Administration with legislative competence over specified matters, and section 113 gives Nevis a constitutional right to secede by a two-thirds referendum. A 1998 secession referendum reached 62 percent, just short of the threshold, which remains the defining fact of the federation's politics.

The federal division of competence is a real trap for advisers, because Nevis legislates separately on land, some taxation and its own financial services sector, so a statute in force in Saint Kitts may have no application in Nevis and vice versa. Always confirm whether the governing instrument is a federal Act or a Nevis Island Assembly Ordinance before advising on a Nevis transaction.

1978 Constitution, a mixed legal system, and the CCJ as final court

The Saint Lucia Constitution Order 1978 created a parliamentary monarchy with a Governor-General representing the King, a bicameral Parliament and an independent judiciary. Chapter I guarantees fundamental rights enforceable in the High Court. Saint Lucia is one of only five CARICOM states to have accepted the appellate jurisdiction of the Caribbean Court of Justice, which replaced the Privy Council as its final court of appeal.

Saint Lucia's mixed system is not a historical curiosity but a live drafting problem: the Civil Code, descended from the Code Napoléon by way of Quebec, governs obligations, property and succession, while procedure, evidence, company law and public law are common law. A pleading that cites English authority on a matter the Civil Code covers, such as prescription or usufruct, will be met with the codal provision instead.

1979 Constitution, retained after the 2009 reform referendum failed

The Saint Vincent and the Grenadines Constitution Order 1979 establishes a parliamentary monarchy with a Governor-General, a unicameral House of Assembly and an independent judiciary, with fundamental rights in Chapter I enforceable in the High Court. A 2009 referendum proposing a new republican constitution with the Caribbean Court of Justice as final court was defeated, so both the monarchy and the Privy Council appeal were retained. The state includes the Grenadines, administered as part of the unitary whole.

The 2009 referendum is the key constitutional fact, because it means every proposal to modernise the constitution or accede to the CCJ now carries the memory of a failed popular vote, and change requires a two-thirds referendum majority under section 38. Constitutional litigation therefore proceeds against an unamended 1979 text with a savings clause that continues to shield some pre-independence laws.

1960 Constitution blending fa'a Samoa with Westminster form

Independent since 1962 under the 1960 Constitution, which grafts Westminster institutions onto fa'a Samoa: the Head of State, a Parliament seated almost entirely by matai title holders, and constitutional protection for custom.

Candidacy for almost every parliamentary seat requires a registered matai title, so the customary chiefly system is a formal qualification for legislative office — a feature with no parallel in the region. The 2020 constitutional amendments were the most contested reform since independence: they reorganised the Land and Titles Court into a separate hierarchy with its own appellate structure outside the Supreme Court, which critics argued created a parallel judiciary and diluted the supremacy of the ordinary courts over custom matters. The 2021 change of government produced a genuine constitutional crisis resolved by the Court of Appeal, confirming that the courts, not the Head of State, determine when Parliament is validly convened. Appeals to the Privy Council were abolished; the Court of Appeal of Samoa is final.

Ancient Statutes, the 1974 Declaration of Rights and six-month Captains Regent

San Marino has no single written constitution. Its constitutional order combines the 1600 Leges Statutae, the 1974 Declaration of Citizens' Rights and constitutional custom, with two Captains Regent serving as joint heads of state for six months.

Outgoing Captains Regent face the sindacato della Reggenza, a public procedure allowing any citizen to complain about their conduct in office.

A Basic Law that names the Qur'an and the Sunna as the constitution

Saudi Arabia has no written constitution in the conventional sense. The 1992 Basic Law of Governance is explicit that the Qur'an and the Prophet's Sunna are the constitution, and the Basic Law itself is subordinate to them.

The Basic Law is best read as an organisational statute rather than a constitution in the Western sense: it describes how the state is arranged, but it does not create rights enforceable against the sovereign, and Article 1's designation of the Qur'an and Sunna as the constitution means legislation is framed as regulation (nizam) subordinate to the sharia rather than as primary law. Royal decrees and royal orders are the operative instruments of lawmaking. The Shura Council may propose and review regulations but cannot enact them over the King's objection. Vision 2030 has driven a rapid and genuine codification programme, but it is a programme of the executive, and its instruments can be amended the same way they were made.

2001 Constitution with a Conseil constitutionnel that has enforced electoral timetables

The Constitution of 22 January 2001 establishes a semi-presidential republic with a five-year presidential term restored by referendum in 2016. The Conseil constitutionnel annulled the 2024 postponement of the presidential election, compelling the vote to proceed.

Senegal is the strongest case in the region for effective constitutional adjudication. In February 2024 the Conseil constitutionnel struck down a law postponing the presidential election and the decree that had cancelled it, holding the postponement unconstitutional; the election proceeded and produced a transfer of power to the opposition. Senegal has never experienced a successful military coup.

The 2006 Constitution with 2022 amendments on judicial independence

Serbia is a parliamentary republic under the 2006 Constitution, amended by referendum in 2022 to remove parliament from judicial appointments. The Constitutional Court reviews the constitutionality and legality of general acts.

The 2022 amendments were an EU accession benchmark, so implementing legislation on the judiciary is central to current reform.

1993 Constitution with a Constitutional Court and a Court of Appeal apex

The 1993 Constitution restored multiparty democracy and contains a Charter of Fundamental Human Rights and Freedoms in Chapter III. The Supreme Court sitting as the Constitutional Court hears constitutional matters, with appeal to the Court of Appeal. Seychelles saw its first peaceful transfer of presidential power in 2020.

Seychelles has retained the Judicial Committee of the Privy Council only for limited historical purposes; the Court of Appeal, staffed substantially by judges from other Commonwealth jurisdictions, is the effective apex. The 1993 Charter has been actively litigated, including on detention conditions and electoral process.

The 1991 Constitution, restored after the civil war, with a dual system of general and chiefdom governance

The Constitution of Sierra Leone 1991 survived the 1991-2002 civil war and remains in force. It provides a presidential system with a unicameral Parliament that includes twelve Paramount Chiefs, and it preserves customary law in the provinces alongside the general law of the Western Area.

The 1991 Constitution was suspended during the war years and restored thereafter; the Constitutional Review Committee reported in 2017 but comprehensive amendment has not been enacted, so the 1991 text with limited amendments governs. Section 171(15) declares the Constitution supreme. Chapter III rights are justiciable through the Supreme Court under s.28, which has exclusive original jurisdiction over constitutional questions, while chapter II fundamental principles are non-justiciable. The territorial dualism is central: the Western Area (Freetown) is governed by the general law, while the provinces operate under a chiefdom administration in which Paramount Chiefs exercise recognised authority and local courts apply customary law. Twelve Paramount Chiefs sit as members of Parliament. The 2022 Public Elections Act changed the parliamentary electoral system, and the 2023 Gender Equality and Women's Empowerment Act reserved 30% of public and private sector positions and candidate slots for women, an unusually strong quota in the region.

Westminster structure with a supreme written constitution and an elected president

The Constitution is supreme and courts may strike down inconsistent legislation, but Parliament is dominant in practice. The elected presidency, created in 1991, holds custodial vetoes over reserves and key appointments rather than executive power.

Part IV guarantees liberties including life, personal liberty, equality, speech and religion, but each is subject to restrictions Parliament may impose on stated grounds, and the courts have read those grounds broadly. Article 5(2A) entrenches core provisions behind a referendum requirement, though it has never been brought into force. The Internal Security Act permits detention without trial on national security grounds, subject to an advisory board rather than ordinary judicial review. Constitutional challenges do succeed on occasion, but the judiciary has generally deferred to Parliament on questions of policy.

A 1992 constitution whose amendments the court cannot review

The Constitution of 1992 contains its own bill of rights. The Constitutional Court in Košice reviews statutes and hears individual complaints, but held in 2019 that it lacks jurisdiction over constitutional amendments themselves after striking down a judicial-vetting amendment.

A complaint must be lodged within two months of a final decision and requires legal representation; the court can award damages as well as quash the decision.

The 1991 Constitution, a dominant National Assembly and a powerful Constitutional Court

Slovenia is a parliamentary republic under the 1991 Constitution. The National Assembly legislates with an advisory National Council able to impose a suspensive veto, and the Constitutional Court is an unusually active guardian of rights.

Referendums have repeatedly shaped Slovenian legislation, though the Constitution now excludes certain subjects from popular vote.

1978 Constitution with custom as a source of law

A Westminster constitution from independence in 1978 with a justiciable fundamental-rights chapter, retaining the King as head of state and expressly recognising custom as a source of law.

Schedule 3 sets the hierarchy of laws: the Constitution, then Acts of Parliament, then customary law, then the common law and equity of England as it stood at independence — with the important qualification that common law applies only so far as it is not inconsistent with custom. That inversion matters in land and family disputes. The rights chapter is enforceable in the High Court. The country's constitutional history is marked by the 1998–2003 conflict and the Regional Assistance Mission that followed, and by the Townsville Peace Agreement; the resulting tension between provincial autonomy and central authority remains the main axis of constitutional debate.

A provisional constitution from 2012, amended in 2024, alongside Somaliland's separate order

The Provisional Constitution of 2012 established a federal republic; the first four chapters were amended in 2024. Federal member state relations remain contested, and Somaliland has operated its own constitutional order since 1991.

Somalia's constitutional position cannot be stated as a single system. The 2012 Provisional Constitution created a federal republic with a bicameral parliament and provided for a Constitutional Court that has never been constituted, so constitutional disputes are resolved politically. The March 2024 amendments to the first four chapters changed the electoral model toward direct universal suffrage and altered the executive structure, and they were contested by Puntland, which announced it would not recognise them pending a national agreement. The allocation of powers and revenue between the federal government and member states is genuinely unsettled rather than merely disputed at the margins. Separately, Somaliland declared independence in 1991, adopted its own constitution by referendum in 2001, and runs its own courts, elections and legal system; it is not internationally recognised, but describing Somali law without noting this would be inaccurate.

A transformative constitution with justiciable socio-economic rights

The 1996 Constitution is the supreme law and is widely regarded as one of the most far-reaching in the world. The Constitutional Court enforces a Bill of Rights that includes housing, health care, water and education as justiciable entitlements, not aspirations. Section 39(2) obliges every court to promote the spirit of the Bill of Rights when developing the common law or customary law, which is why constitutional reasoning reaches deep into private law.

South African constitutionalism replaced parliamentary sovereignty in 1994 and is deliberately 'transformative': the text is read as mandating the reconstruction of an unequal society rather than merely restraining the state. Grootboom and Treatment Action Campaign settled the mechanism — courts test whether a government programme is reasonable rather than ordering a specific budget line, which preserves the separation of powers while still making the social rights enforceable. Chapter 9 institutions, notably the Public Protector and the Auditor-General, are constitutionally independent supports for that order.

A Constitutional Court that has removed two presidents

The 1987 Constitution established a directly elected president and a powerful Constitutional Court with exclusive jurisdiction over constitutional review, impeachment and party dissolution. It has twice ruled on presidential impeachment.

The Court has nine justices serving six-year terms, appointed by the president, the National Assembly and the Chief Justice in equal parts. Six votes are required to invalidate a statute or uphold an impeachment. Its 2004 decision rejected the impeachment of President Roh, while the 2017 decision upheld the impeachment of President Park and removed her from office. The Court has also decided major rights cases on conscientious objection and abortion, striking down the criminal abortion prohibition in 2019.

A transitional constitution from 2011 whose timetable has repeatedly slipped

The Transitional Constitution 2011, amended to incorporate the 2018 Revitalised Peace Agreement, remains in force well past its intended life. A permanent constitution-making process and elections have been repeatedly postponed.

The 2011 text was written for a two-year transition to a permanent constitution and has instead governed for well over a decade, amended to absorb successive peace agreements after the 2013 and 2016 conflicts. The 2018 R-ARCSS created a power-sharing executive with multiple vice-presidents and provided for a permanent constitution and elections; the 2022 Act established the constitution-making machinery, and the timetable has been extended more than once. The Supreme Court holds constitutional jurisdiction but institutional independence is weak and judges have gone on strike over conditions and interference. Customary law is constitutionally recognised and, in practice, resolves the large majority of disputes through customary courts under the Local Government Act 2009. The entry is marked research because the constitutional framework is explicitly provisional and the operative arrangements shift with the peace process rather than with legal amendment.

The 1978 Constitution, a parliamentary monarchy and seventeen autonomous communities

Spain is a parliamentary monarchy under the 1978 Constitution, which ended the transition from dictatorship. Power is extensively devolved to seventeen autonomous communities, and a dedicated Constitutional Court polices both rights and the division of competences.

Many practical disputes are really competence disputes: check whether the applicable rule is state law or the law of the relevant autonomous community before advising.

A 1978 constitution whose executive presidency has been repeatedly re-cut

Sri Lanka's Second Republican Constitution of 1978 created a strong executive presidency, and most constitutional politics since has consisted of amendments enlarging or shrinking it. The 19th Amendment (2015) cut presidential power and restored independent commissions; the 20th (2020) reversed much of that; the 21st (2022) restored parts again after mass protests. Anyone citing the Sri Lankan constitution must say which amendment layer they mean.

The President is directly elected and is head of state, head of government and commander-in-chief. Chapter III guarantees fundamental rights, enforceable only by the Supreme Court and only within one month of the infringement. Buddhism has 'the foremost place' under Article 9, while Article 10 guarantees freedom of conscience. Constitutional amendment requires a two-thirds parliamentary majority, and a referendum for entrenched articles. The one-month window for fundamental rights applications is short and strictly applied — it is the single most common reason a rights case fails. There is no post-enactment judicial review of legislation. Constitutionality must be challenged within one week of a Bill being placed on the Order Paper.

A 2019 transitional document interrupted by a coup and then by war

The 2019 Constitutional Document, amended to incorporate the 2020 Juba Peace Agreement, was the transitional framework after Bashir's removal. The October 2021 coup displaced it and the war that began in April 2023 has made the operative constitutional position impossible to state.

The texts are recorded because they were genuinely enacted, but this entry does not assert a functioning constitutional order. The 2019 Constitutional Charter created a sovereignty council, a civilian cabinet and a transitional legislative council that was never fully seated, and provided for a Constitutional Court that was not effectively constituted. The October 2021 coup removed the civilian prime minister and suspended key provisions. Since April 2023 the country has been in a full internal armed conflict between the SAF and the RSF, with rival claims to state authority, destruction of court infrastructure in Khartoum and displacement of the judiciary. Any statement that Sudan's constitution currently operates in a particular way would be unsupportable from open sources, which is why this carries a research rather than a reviewed stamp.

1987 Constitution, Dutch civil law, with a Constitutional Court since 2020

Suriname is the only Dutch-speaking state in the Americas and applies Dutch-derived civil law. The 1987 Constitution vests legislative power in the Nationale Assemblée, which elects the President. A Constitutional Court, provided for in 1987, was finally installed in 2020 and can review legislation against the Constitution and treaties.

The Constitutional Court's installation in 2020, 33 years after the Constitution provided for it, was a significant institutional development and it promptly addressed the amnesty legislation connected to the 1982 December murders. Suriname's legal literature and legislation are in Dutch, and Dutch jurisprudence remains persuasive, which sets it apart from every other South American system.

Four fundamental laws and independent public agencies

Sweden's constitution comprises four fundamental laws, headed by the 1974 Instrument of Government. A distinctive feature is that ministers cannot direct independent agencies on individual cases.

The 1766 principle of public access to official documents (offentlighetsprincipen) is a constitutional cornerstone that makes Swedish administration unusually transparent.

Direct democracy and a Federal Supreme Court that may not strike down federal statute

The Federal Constitution of 1999 establishes a federal state of 26 cantons with strong direct democracy: citizens can force votes on constitutional amendments (initiative) and on laws (referendum). But Article 190 obliges the Federal Supreme Court to apply federal statutes even where they conflict with the Constitution, so there is no full judicial review of federal law.

Cantonal law can be reviewed against the Constitution, but federal statute cannot, which pushes rights debates into the political arena of referendums and initiatives rather than the courtroom. The Federal Supreme Court will, however, apply the ECHR.

The 2012 Constitution, and a transitional order following the fall of the Assad government

The 2012 Constitution replaced the 1973 text and removed the Ba'ath Party's constitutionally entrenched leading role. Following the change of government in December 2024, Syria entered a transitional constitutional process whose outcome is not settled.

The 2012 Constitution retained a strong presidency, a Supreme Constitutional Court appointed by the President, and Article 3 requiring that the President be Muslim and making Islamic jurisprudence a principal source of legislation. Its practical significance was always limited by emergency rule and by the concentration of power in the presidency. Since December 2024 the constitutional position has been openly transitional, with a declaration of constitutional principles and an announced drafting process. Because the framework is actively being rewritten, anything stated here about Syrian constitutional law should be verified against the current position rather than relied on.

1990 Constitution, semi-presidential, with a Constitutional Court and an autonomous Príncipe

The 1990 Constitution introduced multiparty democracy and a semi-presidential system in which the President and the Prime Minister share executive authority, a division that has produced repeated cohabitation friction. The island of Príncipe has had political and administrative autonomy since 1995. The Tribunal Constitucional exercises constitutional review.

São Tomé and Príncipe is a microstate of about 220,000 people whose semi-presidential design, borrowed from Portugal, has generated frequent institutional conflict between president and government. Príncipe's autonomy statute gives the smaller island its own regional government, an arrangement unusual at this scale.

Indefinite re-election for the incumbent under the 2016 amendments

The 1994 Constitution was amended by referendum in 2016 to remove term limits for the Leader of the Nation, lower the presidential eligibility age and ban faith-based political parties.

The 2016 package exempted the sitting president, styled Leader of the Nation, from term limits, reduced the minimum presidential age from 35 to 30, and prohibited parties based on religion, which removed the Islamic Renaissance Party from lawful politics. The Constitutional Court reviews legislation on referral and on individual application, but in practice rarely constrains the executive. Rights are enumerated in Chapter Two, and Tajikistan is party to the main UN covenants with treaty-body reporting the principal external check.

The 1977 constitution over a two-part union with Zanzibar

The Constitution of 1977, amended many times, governs the United Republic. Zanzibar retains its own constitution, legislature, judiciary and President with authority over non-union matters, and the list of union matters is the constitutional fault line. A 2014 draft constitution was never put to referendum.

Tanzania is a union of two entities with asymmetric autonomy: Zanzibar has its own President, House of Representatives and courts, and the Court of Appeal of Tanzania does not hear appeals on Zanzibari constitutional questions. The 2010 Zanzibar amendment introducing a government of national unity, and the failure of the 2014 draft union constitution, are the two most significant recent constitutional events.

A 2017 constitution written after a coup, with an appointed senate role

Thailand's twentieth constitution since 1932 was promulgated in 2017 following the 2014 coup. It created a Constitutional Court and independent agencies with broad power to remove elected officials, and gave an appointed Senate a role in selecting the prime minister until 2024.

The 2017 text entrenches a 20-year National Strategy that binds subsequent governments, and amendment requires supermajorities plus, for core chapters, a referendum. The Constitutional Court has repeatedly dissolved parties and removed office-holders, most prominently Future Forward in 2020 and Move Forward in 2024, which makes it the decisive actor in Thai politics rather than a residual one. Section 112 of the Criminal Code penalises insulting the monarchy with three to fifteen years per count and is charged frequently; it sits alongside constitutional protections for expression and is the sharpest constraint on political speech.

1973 Constitution with entrenched rights and Privy Council appeals

The Constitution of 1973 established The Bahamas as an independent constitutional monarchy with a Westminster-style Parliament of a Senate and House of Assembly. Chapter III guarantees fundamental rights, enforceable by application to the Supreme Court. Amendments to entrenched provisions, including those on citizenship and the courts, require a referendum, which is why several attempted reforms have failed at the ballot rather than in Parliament.

The referendum requirement for entrenched provisions is the defining feature of Bahamian constitutional practice: proposals on gender equality in citizenship were put to referendum in 2002 and 2016 and rejected both times, so the discriminatory transmission rules remain in the text. That makes litigation, rather than amendment, the practical route for rights arguments in this area.

A semi-presidential republic under the 2002 Constitution

The Constitution of the Democratic Republic of Timor-Leste took effect on 20 May 2002 at the restoration of independence. It creates a semi-presidential system with a directly elected President, a Prime Minister answerable to the National Parliament, and a Court of Appeal that exercises constitutional jurisdiction pending the establishment of a dedicated Supreme Court of Justice.

The Constitution provides for a President elected by direct universal suffrage for a five-year term, renewable once, who can veto legislation and dissolve Parliament in defined circumstances. Executive government rests with a Council of Ministers led by a Prime Minister drawn from the parliamentary majority. Portuguese and Tetum are the official languages, and much foundational legislation exists in Portuguese, which matters practically for anyone researching primary sources. Note the transitional arrangement that still shapes the court structure: the Constitution envisages a Supreme Court of Justice, but it has never been established, and the Court of Appeal in Dili continues to exercise the final appellate and constitutional jurisdiction in its place.

1992 Constitution, changed in 2024 to a parliamentary system with a President of the Council

The 1992 Constitution was substantially revised in 2024, converting Togo from a presidential to a parliamentary system in which a President of the Council of Ministers drawn from the legislative majority holds executive power. The change was adopted by the National Assembly without referendum.

The 2024 revision is the central fact of Togolese constitutional law. By moving executive power to a President of the Council of Ministers accountable to parliament, and removing direct presidential election, it altered the term-limit calculus that had constrained the incumbent, and it was enacted by legislative vote rather than referendum. Opposition parties characterised it as a constitutional coup.

1875 Constitution, never colonised, monarchy reformed in 2010

The only Pacific state never colonised and the region's only monarchy, governed under a constitution granted by King George Tupou I in 1875 — one of the oldest continuously operative constitutions in the world.

The 1875 Constitution was granted, not negotiated, and its continuity is the source of Tonga's distinctive legal order. The 2010 reforms were the decisive modern change: the majority of Legislative Assembly seats became directly elected, the Prime Minister is now drawn from the Assembly rather than appointed by the monarch, and executive power shifted substantially to cabinet — though the King retains significant powers, nine seats remain reserved to the nobility, and the monarch's assent is required for legislation. The reforms followed the 2006 Nuku'alofa riots. A rights chapter exists in the 1875 text and is enforceable, but it is briefer and older in style than modern bills of rights.

1976 Republican Constitution with a savings clause for existing law

Trinidad and Tobago became a republic in 1976, replacing the monarch with a President elected by an Electoral College. The Constitution guarantees fundamental rights in sections 4 and 5, but section 6 saves laws in force before 1976 from challenge on rights grounds, which has shaped decades of litigation. Legislation inconsistent with the protected rights may still be enacted if passed by a three-fifths majority and expressly stated to have that effect.

The savings clause in section 6 is the single most important feature for practitioners, because a claimant challenging a colonial-era provision must first clear the hurdle that the law is saved rather than argue the merits of the rights breach. The Privy Council remains the final appellate court, and proposals to accept the appellate jurisdiction of the Caribbean Court of Justice have not been enacted.

The 2022 constitution replaced the 2014 text with a presidential system

The 2014 constitution, product of the post-revolution constituent assembly, was replaced in 2022 by referendum with a text concentrating power in the presidency and weakening the legislature.

The most important practical fact about Tunisian constitutional law is institutional rather than textual: the Constitutional Court mandated by the 2014 constitution was never established because parliament could not agree appointments, so there was no body to adjudicate the constitutionality of the 2021 emergency measures or the 2022 process. The 2022 constitution, approved on a low turnout, makes the President head of the executive with ministers responsible to him, reduces the Assembly's censure powers, and adds a second chamber of regions and districts. Reference material written between 2014 and 2021 describes a parliamentary system that no longer operates, which is the single most common error in current descriptions of Tunisia. The independence of the judiciary was also restructured after the 2022 dissolution of the Supreme Judicial Council.

An executive presidency since the 2017 referendum

The 1982 Constitution, adopted after the 1980 coup, was amended by referendum in April 2017 to abolish the office of Prime Minister and create an executive presidency. The changes took effect with the 2018 elections. The Constitutional Court hears individual applications alleging violations of fundamental rights.

The 2017 amendments concentrated executive authority in a directly elected President who appoints ministers and vice-presidents without parliamentary confirmation and can issue presidential decrees in areas not reserved to statute. The Constitutional Court retains the power to annul legislation and, since 2012, to hear individual applications after ordinary remedies are exhausted — a mechanism that generates a very large caseload and interacts directly with the European Court of Human Rights, since Turkey is a Council of Europe member. Article 90 gives ratified international human rights treaties precedence over conflicting domestic statutes, which is a significant interpretive tool.

A bicameral 2016-2020 structure abolished again in 2023

The 2016 Constitution created a Halk Maslahaty upper chamber in 2020, then a 2023 amendment abolished it and restored a unicameral Mejlis, with the former president chairing a separate national body.

Constitutional review is a legislative function rather than a judicial one, so there is no court a citizen can petition to strike down a statute. The 2023 restructuring created a standing Halk Maslahaty as a supreme representative body chaired by the former president, sitting above the ordinary organs of state. Rights are enumerated but the state exercises comprehensive control over expression, association and movement, and the country is among the least accessible in the world for independent legal research, so this entry is stamped as research rather than reviewed.

1986 Constitution with Falekaupule authority and climate statehood

A Westminster constitution from 1986, revised in 2023, notable for expressly subordinating some individual rights to Tuvaluan values and community, and for a 2023 amendment addressing statehood against sea-level rise.

Tuvalu's constitution is unusual in stating in its own preamble and principles that individual rights are to be exercised with regard to Tuvaluan values, community and custom — an express communitarian qualification rather than the individualist framing of most rights instruments, and courts have engaged with it in freedom-of-religion cases concerning island-level restrictions on new denominations. The 2023 constitutional revision declared that Tuvalu's statehood and maritime zones endure notwithstanding the effects of climate change and sea-level rise, which is a genuinely novel constitutional provision. The Falekaupule, traditional assemblies of elders, hold devolved statutory power, so local custom operates through a formal legal channel.

The 1995 constitution, with term and age limits removed by amendment

The 1995 constitution established a presidential republic with a justiciable bill of rights and a Constitutional Court. The 2005 amendment removed presidential term limits and the 2017 amendment removed the age limit, both upheld in substance by the Supreme Court.

Uganda's constitutional structure is distinctive in routing constitutional interpretation through the Court of Appeal sitting as a Constitutional Court, with appeal to the Supreme Court — a two-stage process that has made constitutional litigation slow. The 2005 and 2017 amendments removing term and age limits are the substance of most modern constitutional argument, and the Constitutional Court's annulment of the Anti-Homosexuality Act 2014 on quorum grounds is its best-known intervention.

The 1996 constitution operating under martial law

The Constitution of 1996 provides an individual constitutional complaint against statutes applied in a final judgment. Martial law has been in force since February 2022, permitting derogation from several rights, though the constitution forbids amendment while it lasts.

A complaint must be lodged within three months of the final decision and must attack the statute rather than the judgment, and the court's docket delays mean years rather than months.

A federation of seven emirates with substantial reserved powers

The 1971 Constitution creates a federation in which the seven emirates retain everything not expressly given to the federal government, including significant control over land and natural resources.

The reserved-powers structure is the reason a question about UAE law so often has an emirate-level answer: real property, and much of the regulation of economic activity within an emirate, sit with the emirate rather than the federation. Dubai's decision to keep its own courts means there is no single first-instance system across the country. The Federal Supreme Court rules on the constitutionality of federal and local legislation and on inter-emirate disputes, but there is no elected legislature: the Federal National Council is half appointed and half indirectly elected, and its role is consultative.

An uncodified constitution built on parliamentary sovereignty

There is no single constitutional document. Statutes, common law, conventions and devolution settlements together form the constitution, and Parliament remains legally supreme.

Miller (2017) and Miller II (2019) confirmed that even high-politics prerogative decisions are justiciable, making judicial review the central constitutional remedy.

A written constitution with judicial review and strong federalism

The 1788 Constitution is the supreme law. Federal courts may refuse to apply any statute or executive act that conflicts with it, a power asserted in Marbury v. Madison (1803) rather than granted expressly.

There is no general constitutional complaint procedure. Constitutional arguments are raised inside ordinary litigation, which means a claimant needs standing: a concrete, particularised injury that is traceable and redressable.

1967 Constitution with referendum and plebiscite mechanisms

Uruguay's 1967 Constitution, restored in 1985 after the dictatorship, provides for direct-democracy tools used more actively than almost anywhere: citizens can force a referendum to repeal a statute and can initiate constitutional plebiscites. Constitutional review is exercised by the Suprema Corte de Justicia, whose declaration of unconstitutionality applies to the case before it rather than annulling the law generally.

Two features distinguish Uruguayan constitutional law: inter partes constitutional review, so a successful challenge disapplies the statute only for that litigant, and the intensity of direct democracy, which has been used to repeal privatisation laws and to entrench pension rules. The 1989 referendum upholding the amnesty law, and the Supreme Court's later Gelman-driven reversal of that position, illustrate the interaction between popular vote and Inter-American obligations.

A 2023 constitution that reset presidential terms to seven years

A referendum in 2023 adopted extensive amendments, lengthening the presidential term to seven years and resetting the count, while adding social rights and a habeas corpus guarantee.

The 2023 amendments touched roughly two-thirds of the text. They expanded socio-economic guarantees, wrote in the presumption of innocence and a prohibition on torture, introduced Miranda-style rights on arrest, and abolished the death penalty in constitutional terms. The proposal to remove Karakalpakstan's sovereign status and right to secede was withdrawn after protests in Nukus in July 2022 that ended in deaths and prosecutions, and the final text retained that status. The presidential term was extended to seven years with the incumbent's prior terms discounted.

1980 Constitution keeping both English and French law in force

The atlas's clearest mixed jurisdiction. The Anglo-French condominium left both English common law and French civil law in force at independence in 1980, and the Constitution keeps both until replaced by Parliament.

Article 95(2) continues both British and French law in force so far as not incompatible with independence or expressly revoked, which means a Vanuatu court may be asked to apply a French civil-law rule and an English common-law rule in adjoining fields. Custom is also a source of law, and the Malvatumauri National Council of Chiefs has a constitutional role on questions of custom and tradition, though it is advisory rather than legislative. Articles 73 to 75 did something no other jurisdiction in the region did so completely: all land reverted to its indigenous custom owners at independence, extinguishing colonial freehold outright. The rights chapter is justiciable in the Supreme Court.

1999 Constitution with five branches and a contested judiciary

The 1999 Constitution establishes five branches of государственной power — executive, legislative, judicial, citizen and electoral — adding the Poder Ciudadano (Ombudsman, Public Ministry, Comptroller) and the Poder Electoral to the classical three. The Tribunal Supremo de Justicia's Sala Constitucional exercises concentrated review. International bodies have extensively questioned judicial independence, and Venezuela denounced the American Convention in 2012.

The five-branch structure is Venezuela's most distinctive formal constitutional feature, and the Sala Constitucional has power to review and annul decisions of the other chambers of the Supreme Tribunal itself. Venezuela's 2012 denunciation of the American Convention on Human Rights took effect in 2013, removing individual access to the Inter-American Court for subsequent events, though the Inter-American Commission retains competence under the OAS Charter and the American Declaration.

Party leadership in Article 4 and a National Assembly that reviews its own laws

The 2013 Constitution names the Communist Party as the leading force in Article 4. There is no constitutional court: the National Assembly supervises constitutionality itself, so ordinary courts cannot invalidate legislation.

Chapter II sets out extensive rights, including a 2013 addition of a right to life, but Article 14(2) permits restriction by law for national defence, security, social order and public health, and those grounds are applied generously. Since 2016 the Supreme People's Court has published selected case precedents that lower courts must follow, a notable departure for a civil-law socialist system. Constitutional amendment requires two-thirds of the National Assembly. In practice the decisive documents are often Party resolutions and implementing decrees rather than the constitutional text, and the hierarchy of legal documents statute is the practical tool for resolving conflicts.

A 1991 constitution suspended in practice by partition and war

The 1991 unification constitution remains the nominal framework, but since 2014 the state has been divided between the internationally recognised government and the Houthi authorities in Sanaa.

Any account of Yemeni constitutional law that describes a single functioning system is inaccurate. The 1991 constitution formally governs, and the draft federal constitution of 2015 was never adopted. Since 2014 the Houthi authorities have administered Sanaa and the northern highlands with their own appointments and their own Supreme Political Council, while the recognised government operates from Aden through a Presidential Leadership Council formed in 2022. Courts in both areas issue judgments in the name of the Republic. Which authority controls the relevant territory determines which law is enforced in practice, and this entry is recorded as research rather than reviewed because the position cannot be verified from open sources with confidence.

1991 Constitution as amended in 2016, with a Constitutional Court since 2016

The Constitution of 1991, substantially amended by Act 2 of 2016, created a separate Constitutional Court and introduced a presidential running-mate system and a 50-per-cent-plus-one election threshold. Part III contains the Bill of Rights, which the 2016 amendment notably did not expand — an attempt to do so failed at referendum.

The 2016 reform split the apex: a Constitutional Court for constitutional questions and the Supreme Court for the rest, with a Court of Appeal inserted below both. Because the 2016 referendum on an expanded Bill of Rights failed to reach the required threshold, Part III remains the pre-1996 text, so Zambia has a modernised court structure applying an older rights instrument.

2013 Constitution with a dedicated Constitutional Court and an expansive Bill of Rights

The 2013 Constitution replaced the Lancaster House text and created a standalone Constitutional Court as the apex on constitutional matters, with the Supreme Court remaining final on everything else. Chapter 4 contains a long Declaration of Rights including socio-economic provisions, and Chapter 15 recognises customary law and traditional leaders.

The 2013 text is generous on paper and its implementation has been contested, particularly around amendments affecting judicial tenure. The two-apex structure — Constitutional Court for constitutional matters, Supreme Court otherwise — is the practical point of departure for any appeal strategy.
