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	Unitary with seventeen departments and the capital district, each with an elected governor and departmental board holding administrative and limited fiscal competence. Legislative power is national.	Unitary with ten districts, and a recognised hierarchy of chiefs exercising customary functions over land allocation and local dispute resolution. The Senate includes the twenty-two principal chiefs ex officio.	Unitary and highly centralised — Nauru has no second tier of general government. The Nauru Island Council was abolished in 1999, so the state deals directly with citizens, though the 14 districts remain the basis for parliamentary constituencies and the twelve tribes retain social significance in land and title questions.	Federal. Powers not expressly granted to the union are reserved to the 32 states (Article 124). States run their own civil, family and criminal-enforcement codes, but criminal procedure, labour and commercial law were federalised to produce single national codes.
How law is made	Bills may start in either chamber and must pass both. The President may object in whole or part; Congress overcomes an objection by absolute majority in both chambers. Constitutional amendment requires a two-thirds vote of each chamber and ratification by referendum; wholesale reform requires a constituent assembly.	Bills pass three readings in the National Assembly, go to the Senate for review, and receive royal assent. The Senate can delay but not indefinitely block ordinary bills. Amendments to entrenched constitutional provisions require a two-thirds majority and, for the most protected clauses, a referendum.	Bills receive three readings in the 19-member chamber and are assented to by the President. Ordinary legislation needs a simple majority, but the entrenched provisions of Part XI require a two-thirds majority and, for the most protected articles, approval at a referendum — the barrier that defeated the 2010 reform proposals.	Bills may be introduced by the President, either chamber, state legislatures or by citizens with 0.13% of the electoral roll. Both chambers must pass an identical text; the President may veto, and Congress overrides with two-thirds of each chamber. Constitutional amendments need two-thirds of Congress plus a majority of state legislatures (Article 135).
Legal profession	A law degree and registration of the title with the Supreme Court, which maintains the roll and exercises discipline. Bar membership is voluntary. Because both Spanish and Guaraní are official, courts must provide interpretation, and practitioners outside Asunción are commonly bilingual.	A split profession in form — advocates and attorneys are separately admitted under the Legal Practitioners Act — though in practice many practitioners hold both admissions; the Law Society of Lesotho regulates the attorneys' branch.	A very small fused profession admitted by the Supreme Court under the Legal Practitioners Act 1973, supplemented by pleaders — non-lawyers licensed to appear in the District Court and before the Lands Committee, a practical necessity given the number of resident lawyers. Judicial officers are frequently appointed from Australia, New Zealand or elsewhere in the Pacific.	A law degree plus a cédula profesional from the Education Ministry licenses practice; there is no compulsory bar examination or single mandatory bar, which distinguishes Mexico from most of the region. Notaries public are a separate, strictly limited state-appointed profession with exclusive competence over real estate and company deeds.

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.
