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 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.	Power is concentrated in the Supreme Pontiff, exercised through the Pontifical Commission for Vatican City State (legislative), the Governorate (executive) and the Vatican tribunals (judicial).
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.	Laws are prepared by the Pontifical Commission and take effect with the Pope’s approval, published in the Acta Apostolicae Sedis supplement.
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.	Advocates are enrolled with the Vatican tribunals; canon lawyers (canonists) practise before ecclesiastical courts.

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.
