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	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.	Unitary. Eleven governorates headed by appointed governors, with municipal councils holding advisory functions over local services. No legislative competence exists below the national level.	Nominally unitary with governorates and municipalities. In practice authority is divided between competing administrations and local armed actors, and municipal councils have in many places become the most functional layer of government.
How law is made	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.	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.	There is no single functioning legislative process. The House of Representatives passes laws that the High Council of State contests, and the rival administrations issue decrees within their areas of control. Whether a given instrument is law therefore depends on which authority is recognised, which is exactly why this profile is marked as requiring research rather than described as settled.
Legal profession	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.	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.	Advocates are admitted through the Libyan Bar Association, and the profession has continued to function, including in human-rights litigation, despite serious risks to practitioners. Judicial appointments run through the Supreme Judicial Council. Reliable current information on admission requirements and numbers is limited, which is reflected in the verification status of this entry.

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.
