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	Presidential system with a Prime Minister, a unicameral National Assembly, and a separate Zanzibar government with its own House of Representatives and judiciary up to the Zanzibar High Court.	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 decentralised, with twenty-five regional governments and the Lima Metropolitan Municipality holding elected councils and administrative competence. Peasant and native communities exercise jurisdiction within their territory under Article 149 in coordination with the justices of the peace.
How law is made	Bills are read three times with committee scrutiny in the National Assembly. Bills affecting Zanzibar's Union interests require particular majorities. The President assents; a returned bill passed again by two-thirds must be assented to or the Assembly dissolved.	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 come from Congress, the executive, regional governments or citizens. A single chamber debates in committee and plenary; a second vote is required unless exempted. The President may observe a bill, and Congress insists by absolute majority. Constitutional amendment needs an absolute majority in two successive ordinary legislatures, or a two-thirds vote plus referendum.
Legal profession	Fused; advocates are admitted to the roll of the High Court after an LLB and the Law School of Tanzania, with the Tanganyika Law Society as the mainland professional body.	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 law degree followed by a bachiller and título de abogado, then compulsory registration with one of the departmental colegios de abogados, which hold disciplinary power. Registration in one college permits practice nationwide. Notaries are a separate profession appointed by competitive examination.

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.
