What is the supreme law of Guinea-Bissau, and where is it officially published?
The Constitution of the Republic of Guinea-Bissau (Constituição da República da Guiné-Bissau), adopted in 1984 and subsequently revised, is the country's supreme law and sits at the top of a civil-law system of Portuguese tradition. Like all national legislation, it is promulgated and published in the official gazette, the Boletim Oficial da República da Guiné-Bissau.

Why Lawstronaut for Bissau-Guinean legal research
Bissau-Guinean legal information is spread across the official gazette, the legislature, ministries, national and regional regulators, the national courts, and supranational OHADA and UEMOA sources. For humans, that means slow research. For AI systems, it's a bigger problem: fragmented source access, inconsistent formats, missing provenance, and weak citation trails.
Lawstronaut turns those sources into one structured legal data layer — source links, metadata, full text, versioning, and API/MCP access. Your product or agent retrieves the legal source directly instead of relying on generic web search or unverified model memory. Every answer carries a citation, a timestamp, and a link to the official document — the provenance that makes a legal research platform defensible to auditors and regulators.
About Guinea-Bissau legal coverage
Guinea-Bissau is a civil-law jurisdiction rooted in the Portuguese legal tradition, a legacy of its history as a Portuguese colony until independence in 1973–74. Primary legislation is enacted by the Assembleia Nacional Popular and the Government and published in the official gazette, the Boletim Oficial da República da Guiné-Bissau, issued by the Imprensa Nacional. The judiciary is headed by the Supremo Tribunal de Justiça, with a Tribunal de Contas overseeing public finances. Legal materials are published in Portuguese, the official language.
Guinea-Bissau's legal landscape is shaped as much by regional integration as by domestic legislation: as a member of OHADA, its business, commercial, and insolvency law is governed directly by the OHADA Uniform Acts and interpreted by the Cour Commune de Justice et d'Arbitrage, while as a member of the West African Economic and Monetary Union (UEMOA) it uses the CFA franc and is regulated in banking and finance by the BCEAO. Because national statutes, OHADA Uniform Acts, and UEMOA regulations change on different cycles, citations to outdated provisions can simply be wrong. Point-in-time data straight from the source is what keeps a Guinea-Bissau legal research answer correct today.
