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	A republic of sixteen states, each with its own constitution, governor and legislature, over a small population — Palau has more layers of government per head than almost anywhere. The national Council of Chiefs, made up of the paramount chief of each state, advises the President on custom and traditional law, and the two highest-ranking chiefly titles of Koror and Melekeok carry particular weight.	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 must pass both the Senate and the House of Delegates and are then presented to the President, who may veto; Congress may override with a two-thirds vote of each chamber. Because the House gives every state one delegate regardless of population, the smallest states hold disproportionate weight in the second chamber. Constitutional amendments require a three-quarters vote of each house or a convention, followed by approval at referendum in a majority of the states.	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	Admission is to the Supreme Court under rules that recognise United States bar qualifications, and a substantial part of the bar and bench trained in the US. Palau also licenses trial assistants to appear in the Court of Common Pleas and the Land Court, which is how much routine representation is provided. Land Court practice is a specialism in itself, given the layers of Spanish, German, Japanese and Trust Territory administration that Palauan title claims have to be traced through.	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.
