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 four regions and 55 tinkhundla constituencies that combine electoral and administrative functions. Chiefs administer Swazi Nation Land under the King as trustee.	Federal. Twenty-three provinces plus the autonomous City of Buenos Aires retain all powers not delegated to the nation (Article 121). Substantive civil, commercial, criminal and labour law is federal and uniform, but each province legislates its own procedure and runs its own judiciary — an inversion of the United States allocation.
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 the House of Assembly and Senate and require royal assent, which the King may withhold. The King may also legislate by decree in defined circumstances, and bills touching Swazi law and custom are referred to traditional structures. Constitutional amendment requires a two-thirds majority of both chambers sitting jointly, and for entrenched provisions a referendum.	Bills may be introduced in either chamber, by the executive, or by citizen initiative. One chamber acts as chamber of origin and the other as revising chamber; insistence rules resolve disagreement. The President may veto in whole or in part, and Congress overrides with two-thirds of both chambers. Necessity-and-urgency decrees are permitted but excluded from criminal, tax, electoral and party matters, and must pass a bicameral committee.
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 fused profession of attorneys admitted by the High Court after a law degree and articles, regulated by the Law Society of Eswatini; advocates may be admitted separately for higher-court work.	A five-to-six-year law degree followed by mandatory registration with a provincial or city bar association, which holds disciplinary power. The Colegio Público de Abogados de la Capital Federal governs practice in Buenos Aires. There is no separate bar examination; enrolment follows the degree. Notaries (escribanos) are a distinct numerus clausus profession with exclusive competence over real estate transfers.

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.
