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. The Legislative Assembly legislates for the whole kingdom, and the island divisions of Tongatapu, Vava'u, Ha'apai, 'Eua and the Niuas are administrative districts headed by governors. Below that, town and district officers are elected under the Fakafekau'aki and District and Town Officers Act.	Unitary. Six governorates administered by appointed governors, with no legislative competence.
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 Legislative Assembly and require the King's assent, which is a real rather than purely formal step. Ordinary bills need a simple majority. Amendments to the Constitution require a majority in the Assembly at three separate readings and the consent of the King and Privy Council, and clause 79 forbids any amendment affecting the law of liberty, the succession to the throne or the titles and hereditary estates of the nobles.	Under the constitution as designed, bills passed by the National Assembly required Emiri sanction, and the Emir could return a bill for reconsideration which the Assembly could override by a two-thirds majority. With the Assembly dissolved and the relevant articles suspended since May 2024, legislation is made by Emiri decree on the proposal of the Council of Ministers and published in the Official Gazette (Kuwait Al-Youm).
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.	Law practitioners are admitted by the Chief Justice and licensed under the Law Practitioners Act, with the Tonga Law Society as the professional body. Most qualify overseas or at the University of the South Pacific. A practitioner working on land must know the Land Act's allotment system rather than general property law, because the constitutional bar on selling land means conveyancing in the ordinary sense does not exist.	Advocacy is reserved to Kuwaiti nationals enrolled with the Ministry of Justice and the Kuwait Bar Association, with foreign lawyers acting as consultants and unable to appear; pleadings are in Arabic. Judges are appointed by the Supreme Judicial Council, and a significant proportion of the bench has historically been seconded from other Arab states. Notarial authentication at the Ministry of Justice is required for powers of attorney, property transfers and company formation documents.

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.
