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, organised on the principle of a single system of state power. The 2019 Constitution and the 2019 territorial reform recognise 15 provinces and the special municipality of Isla de la Juventud, with provincial governors appointed on the President's nomination.
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.	Legislative initiative lies with deputies, the Council of State, the Council of Ministers, the courts, the Prosecutor General, mass organisations and 10,000 citizens by popular initiative. The Assembly meets in short ordinary sessions, so much law is made by decree-law of the Council of State and subsequently ratified. Constitutional amendment requires two-thirds of the Assembly, and a referendum for provisions on the political system or rights.
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.	Practising litigators generally work through the Organización Nacional de Bufetes Colectivos, a self-financing national body of collective law offices; independent private practice is not a recognised route. Membership of the Unión Nacional de Juristas de Cuba is the professional association. Notarial functions are performed by state notaries.

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.
