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.	Nine Länder hold their own constitutions, parliaments and governments, but the federation retains far more legislative power than in Germany or Switzerland; much Länder activity is administering federal law (mittelbare Bundesverwaltung). Three separate high courts sit at the apex, for constitutional, administrative and ordinary matters respectively.	A strongly presidential system with a bicameral Parliament of National Assembly and Senate, and a judiciary in which the Supreme Court sits above separate common-law and civil-law appellate structures.
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, members of the Nationalrat, the Bundesrat or a popular initiative, and pass three readings in the Nationalrat. The Bundesrat may object but can normally be overridden. The Federal President authenticates the law, the Chancellor countersigns, and it is published in the Bundesgesetzblatt.	Bills pass committee and plenary in the National Assembly and are transmitted to the Senate; disagreement is resolved by a joint commission or a second Assembly vote. The President promulgates or may seek constitutional review.
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 Rechtsanwalt qualifies through a law degree, five years of practical training including at least three in a law firm and some months at court, and the bar examination. Admission is via the regional bar chambers under the umbrella of the Österreichischer Rechtsanwaltskammertag. Notaries are a separate profession with appointments limited in number.	A single bar for both legal zones: advocates admitted to the Cameroon Bar Association may practise in common-law and civil-law courts alike, which makes bilingual competence a practical necessity.

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.
