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 but substantially regionalised since 2015, with twelve regions holding directly elected councils and their own budgets under the advanced regionalisation programme. Regions have executive competences in development planning and transport; they do not legislate.	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.
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 may be introduced by the head of government or by members of either chamber. They pass through committee and plenary in both houses, with the House of Representatives having the final word where the chambers disagree. Organic laws must be referred to the Constitutional Court before promulgation. The King promulgates statutes by dahir within thirty days, and may ask parliament to reconsider a bill or submit it to referendum.	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.
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.	Avocats are admitted to one of the regional bars and organised nationally through the Association des Barreaux du Maroc; practice before the Court of Cassation requires additional seniority. Notaries and adouls coexist — the notaire handles conveyancing and company documents in the French tradition, while the adoul draws up marriage and inheritance instruments under Islamic law. Judges are career appointments trained at the Institut Supérieur de la Magistrature.	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.

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.
