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.	Federal. Grande Comore, Anjouan and Mohéli each have a governor and their own assembly with substantial autonomy over local administration, while the Union handles defence, currency, foreign affairs and nationality.	A tripartite separation under Article 10, with a directly elected President holding a legislative veto that only a three-fifths Sejm majority can override.
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 originate with the government or members of the Assembly of the Union, are examined in committee and passed by the Assembly, then promulgated by the President. Matters within island competence are legislated by the island assemblies, and disputes over the boundary between Union and island competence are a standing feature of Comorian constitutional practice.	A bill passes three readings in the Sejm, goes to the Senate, which may amend or reject within 30 days, returns to the Sejm, and is then signed by the President — who may instead veto it or refer it to the Constitutional Tribunal.
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 small bar of avocats admitted after French-model legal training, supplemented by qadis who require religious-law qualification for the personal-status jurisdiction; many practitioners train in France or Madagascar.	Two advocacy professions exist side by side: adwokaci and radcowie prawni, both with rights of audience after a bar traineeship and examination. Notaries and bailiffs are separate regulated professions.

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.
