Division of powers	Presidential system with a Prime Minister, a unicameral National Assembly, and a separate Zanzibar government with its own House of Representatives and judiciary up to the Zanzibar High Court.	Unitary. Parliament legislates for the whole country. Below it, about 250 villages govern themselves through the village fono (council of matai) under the Village Fono Act 1990, which gives customary village authority statutory recognition — a genuine layer of local government rather than a delegation of central power.	Unitary. Nineteen departments have elected intendentes and juntas with administrative and local taxing competence, and municipalities were added in 2010, but all legislative power belongs to the General Assembly.
How law is made	Bills are read three times with committee scrutiny in the National Assembly. Bills affecting Zanzibar's Union interests require particular majorities. The President assents; a returned bill passed again by two-thirds must be assented to or the Assembly dissolved.	Bills are read three times in the Legislative Assembly, usually with parliamentary committee scrutiny, and are then assented to by the O le Ao o le Malo. Ordinary bills need a simple majority. Constitutional amendments require a two-thirds majority of all members at the third reading, and any amendment affecting customary land or matai titles is politically entrenched by the strength of the fa'a Samoa consensus even where the two-thirds threshold is met.	Bills pass both chambers; disagreement is resolved by the General Assembly sitting jointly. The executive may veto, overcome by three-fifths of the joint assembly. Distinctively, 25% of registered voters can force a referendum to repeal a statute within one year of promulgation, and 10% can initiate a constitutional plebiscite.
Legal profession	Fused; advocates are admitted to the roll of the High Court after an LLB and the Law School of Tanzania, with the Tanganyika Law Society as the mainland professional body.	A fused profession under the Lawyers and Legal Practice Act 2014: lawyers are admitted by the Supreme Court and must hold a practising certificate from the Samoa Law Society. Most qualify at the University of the South Pacific or in New Zealand. Practice before the Land and Titles Court is different in character from ordinary litigation, because the issues are matai genealogy and customary entitlement rather than statutory or common-law rights.	A degree from the Universidad de la República or an accredited private faculty confers the title of abogado, with registration by the Supreme Court. Membership of the Colegio de Abogados del Uruguay is voluntary; the Supreme Court exercises discipline. Escribanos públicos are a separate profession with exclusive competence over conveyancing.

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.
