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 and decentralised, with twenty-five regional governments and the Lima Metropolitan Municipality holding elected councils and administrative competence. Peasant and native communities exercise jurisdiction within their territory under Article 149 in coordination with the justices of the peace.	Unitary. The state comprises Grenada, Carriacou and Petite Martinique; Carriacou and Petite Martinique have a Ministry and local administration but no separate legislature.	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.
How law is made	Bills come from Congress, the executive, regional governments or citizens. A single chamber debates in committee and plenary; a second vote is required unless exempted. The President may observe a bill, and Congress insists by absolute majority. Constitutional amendment needs an absolute majority in two successive ordinary legislatures, or a two-thirds vote plus referendum.	Bills pass three readings in both Houses and receive the Governor-General's assent. Constitutional amendments to entrenched provisions need a two-thirds majority in the House of Representatives and then approval by a referendum, a double lock that has defeated every reform package put to voters.	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.
Legal profession	A law degree followed by a bachiller and título de abogado, then compulsory registration with one of the departmental colegios de abogados, which hold disciplinary power. Registration in one college permits practice nationwide. Notaries are a separate profession appointed by competitive examination.	A fused profession of legal practitioners admitted by the High Court under the Legal Profession Act, after a law degree and the Legal Education Certificate. The Grenada Bar Association represents practitioners.	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 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.
