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. The state comprises Grenada, Carriacou and Petite Martinique; Carriacou and Petite Martinique have a Ministry and local administration but no separate legislature.	Unitary, with 31 provinces headed by governors-general appointed by the Interior Ministry, alongside elected city and village councils created by the Constitution and operating since 1999 with limited competences.
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.	Bills pass three readings in both Houses and receive the Governor-General's assent. Constitutional amendments to entrenched provisions need a two-thirds majority in the House of Representatives and then approval by a referendum, a double lock that has defeated every reform package put to voters.	A bill is introduced by the Government or by at least fifteen deputies, passes the Majlis, and goes to the Guardian Council, which has ten days, extendable, to find it consistent with Islam and the Constitution. If the Council objects, the bill returns for amendment; persistent disagreement goes to the Expediency Discernment Council, whose decision is final. Only then does the President sign and publish.
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.	A fused profession of legal practitioners admitted by the High Court under the Legal Profession Act, after a law degree and the Legal Education Certificate. The Grenada Bar Association represents practitioners.	Two parallel routes to practice, which is unusual and consequential: attorneys licensed by the Iranian Bar Association (Kanoon-e Vokala), a self-governing body dating to 1953, and attorneys licensed under Article 187 of the Third Development Plan directly by the judiciary. The two groups have contested each other's standing for two decades. Notaries operate licensed offices under the registration organisation, and their authentication is required for property transfers, marriage contracts and powers of attorney.

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.
