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. 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.	Federal. Grande Comore, Anjouan and Mohéli each have a governor and their own assembly with substantial autonomy over local administration, while the Union handles defence, currency, foreign affairs and nationality.	Unitary, with 24 governorates and an elected local tier whose powers were expanded by the 2018 Code of Local Authorities and then reduced when elected municipal councils were dissolved in 2023. The 2022 constitution adds a chamber of regions and districts to represent local government nationally.
How law is made	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.	Bills originate with the government or members of the Assembly of the Union, are examined in committee and passed by the Assembly, then promulgated by the President. Matters within island competence are legislated by the island assemblies, and disputes over the boundary between Union and island competence are a standing feature of Comorian constitutional practice.	Bills are introduced by the President or by at least ten members of the Assembly, with government bills taking priority. They are considered in committee and plenary; finance and organic bills follow reinforced procedures. The President promulgates statutes and may return a bill for reconsideration or put it to referendum. Since 2021 a substantial volume of law has been made by presidential decree-law, which remains in force without subsequent parliamentary ratification.
Legal profession	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.	A small bar of avocats admitted after French-model legal training, supplemented by qadis who require religious-law qualification for the personal-status jurisdiction; many practitioners train in France or Madagascar.	Avocats are admitted through the Ordre National des Avocats de Tunisie after a professional certificate and pupillage, and the Ordre has historically been a significant political actor — it shared the 2015 Nobel Peace Prize as part of the National Dialogue Quartet. Judges are career appointments trained at the Institut Supérieur de la Magistrature; the independence of judicial appointments has been the central controversy since the dissolution of the elected judicial council in 2022.

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.
