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. | Power is concentrated in the Supreme Pontiff, exercised through the Pontifical Commission for Vatican City State (legislative), the Governorate (executive) and the Vatican tribunals (judicial). |
| 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. | Laws are prepared by the Pontifical Commission and take effect with the Pope’s approval, published in the Acta Apostolicae Sedis supplement. |
| 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 enrolled with the Vatican tribunals; canon lawyers (canonists) practise before ecclesiastical courts. |
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.
