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.	A constitutional monarchy with the King as head of state, an executive led by the President of the Government, a bicameral parliament and an independent judiciary, overlaid by extensive regional self-government.	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, with 58 wilayas headed by walis appointed by the President alongside elected wilaya assemblies, and communes below them. Local bodies administer central policy and hold limited own-source revenue; they do not legislate.
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.	Bills pass both chambers of the Cortes Generales, with the Congress of Deputies able to override the Senate, and receive royal assent.	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 come from the government or from at least twenty members of either chamber. They are examined in committee, passed by the People's National Assembly and then the Council of the Nation, with a joint commission resolving disagreement. Organic laws require an absolute majority in the lower house and a three-quarters majority in the upper, plus mandatory constitutional review. The President promulgates within thirty days and may seek a second reading requiring a two-thirds majority to overcome.
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.	Abogados belong to local bar associations (colegios de abogados); procuradores represent parties procedurally and notaries authenticate deeds and company acts.	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.	Avocats are admitted through regional bars coordinated by the Union Nationale des Ordres des Avocats, with separate accreditation required for appearance before the Supreme Court and Council of State. Judges and prosecutors form a single career magistracy trained at the École Supérieure de la Magistrature. Notaries and bailiffs are regulated public officers in the French tradition, and notarial deeds are compulsory for real-property transfers.

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.
