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. Eleven governorates headed by appointed governors, with municipal councils holding advisory functions over local services. No legislative competence exists below the national level. | 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. | Draft legislation is prepared by ministries and the Council of Ministers, may be referred to the Council of Oman for review, and takes effect on the Sultan's signature and publication in the Official Gazette. The Majlis al-Shura may propose legislation and question ministers, and its role was modestly strengthened after 2011, but it cannot enact or block a royal decree. | 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. | Advocacy is regulated by the Ministry of Justice and Legal Affairs; Omani nationality is required for rights of audience, and foreign lawyers practise as consultants within licensed firms. Pleadings are in Arabic. Judges are appointed by royal decree on the recommendation of the Supreme Judicial Council. Notarisation is required for real property dispositions, and land registration is administered by the Ministry of Housing and Urban Planning. | 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.
