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	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 and highly centralised — Nauru has no second tier of general government. The Nauru Island Council was abolished in 1999, so the state deals directly with citizens, though the 14 districts remain the basis for parliamentary constituencies and the twelve tribes retain social significance in land and title questions.	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.
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 receive three readings in the 19-member chamber and are assented to by the President. Ordinary legislation needs a simple majority, but the entrenched provisions of Part XI require a two-thirds majority and, for the most protected articles, approval at a referendum — the barrier that defeated the 2010 reform proposals.	Bills pass both chambers of the Cortes Generales, with the Congress of Deputies able to override the Senate, and receive royal assent.
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 very small fused profession admitted by the Supreme Court under the Legal Practitioners Act 1973, supplemented by pleaders — non-lawyers licensed to appear in the District Court and before the Lands Committee, a practical necessity given the number of resident lawyers. Judicial officers are frequently appointed from Australia, New Zealand or elsewhere in the Pacific.	Abogados belong to local bar associations (colegios de abogados); procuradores represent parties procedurally and notaries authenticate deeds and company acts.

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.
