Comparison

Read two legal systems against each other

Because every portal follows the same fifteen-section outline, the comparison is genuinely like-for-like rather than a collage of whatever each government happens to publish.

Division of powers	Unitary with seventeen departments and the capital district, each with an elected governor and departmental board holding administrative and limited fiscal competence. Legislative power is national.	Unitary, with 31 provinces headed by governors-general appointed by the Interior Ministry, alongside elected city and village councils created by the Constitution and operating since 1999 with limited competences.	Unitary with ten districts, and a recognised hierarchy of chiefs exercising customary functions over land allocation and local dispute resolution. The Senate includes the twenty-two principal chiefs ex officio.	Unitary and highly centralised — Nauru has no second tier of general government. The Nauru Island Council was abolished in 1999, so the state deals directly with citizens, though the 14 districts remain the basis for parliamentary constituencies and the twelve tribes retain social significance in land and title questions.
How law is made	Bills may start in either chamber and must pass both. The President may object in whole or part; Congress overcomes an objection by absolute majority in both chambers. Constitutional amendment requires a two-thirds vote of each chamber and ratification by referendum; wholesale reform requires a constituent assembly.	A bill is introduced by the Government or by at least fifteen deputies, passes the Majlis, and goes to the Guardian Council, which has ten days, extendable, to find it consistent with Islam and the Constitution. If the Council objects, the bill returns for amendment; persistent disagreement goes to the Expediency Discernment Council, whose decision is final. Only then does the President sign and publish.	Bills pass three readings in the National Assembly, go to the Senate for review, and receive royal assent. The Senate can delay but not indefinitely block ordinary bills. Amendments to entrenched constitutional provisions require a two-thirds majority and, for the most protected clauses, a referendum.	Bills receive three readings in the 19-member chamber and are assented to by the President. Ordinary legislation needs a simple majority, but the entrenched provisions of Part XI require a two-thirds majority and, for the most protected articles, approval at a referendum — the barrier that defeated the 2010 reform proposals.
Legal profession	A law degree and registration of the title with the Supreme Court, which maintains the roll and exercises discipline. Bar membership is voluntary. Because both Spanish and Guaraní are official, courts must provide interpretation, and practitioners outside Asunción are commonly bilingual.	Two parallel routes to practice, which is unusual and consequential: attorneys licensed by the Iranian Bar Association (Kanoon-e Vokala), a self-governing body dating to 1953, and attorneys licensed under Article 187 of the Third Development Plan directly by the judiciary. The two groups have contested each other's standing for two decades. Notaries operate licensed offices under the registration organisation, and their authentication is required for property transfers, marriage contracts and powers of attorney.	A split profession in form — advocates and attorneys are separately admitted under the Legal Practitioners Act — though in practice many practitioners hold both admissions; the Law Society of Lesotho regulates the attorneys' branch.	A very small fused profession admitted by the Supreme Court under the Legal Practitioners Act 1973, supplemented by pleaders — non-lawyers licensed to appear in the District Court and before the Lands Committee, a practical necessity given the number of resident lawyers. Judicial officers are frequently appointed from Australia, New Zealand or elsewhere in the Pacific.

A comparison table flattens nuance by design. Where a difference matters to a decision you are making, open both portals and read the section in full — the constitutional detail behind a one-line summary is often the part that governs the outcome.
