What is the supreme law of São Tomé and Príncipe, and what is the source of its current text?
The Constitution of the Democratic Republic of São Tomé and Príncipe is the country's supreme law. First adopted in 1975 and revised several times since, its current consolidated text results from the constitutional revision enacted by Law No. 1/2003, published in the Diário da República — the official gazette.

Why Lawstronaut for São Toméan legal research
São Toméan legal information is spread across the official gazette, government ministries, statutory agencies, regulators, courts, and publication 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 São Tomé and Príncipe legal coverage
São Tomé and Príncipe is a civil-law jurisdiction shaped by the Portuguese (Lusophone) legal tradition, reflecting its history as a former Portuguese territory that became independent in 1975. It has a unified national legal system. Primary legislation — laws (leis) of the National Assembly, decree-laws (decretos-lei), and decrees (decretos) — is published in the Diário da República, the country's official gazette. Regulatory policy and guidance sit across ministries and statutory agencies, including the Banco Central de São Tomé e Príncipe (BCSTP) and the Autoridade Geral de Regulação (AGER). The judiciary is headed by the Supremo Tribunal de Justiça, with constitutional matters before the Tribunal Constitucional. Legal materials are published in Portuguese, the country's official language.
São Toméan law continues to evolve: the Constitution has been revised since independence — most significantly by the constitutional revision enacted as Law No. 1/2003 — and the legal framework for investment, banking, and the emerging oil-and-gas sector has been reformed as the country develops its Gulf of Guinea resources. Citations to superseded provisions can simply be wrong. Point-in-time data straight from the source is what keeps a São Tomé and Príncipe legal research answer correct today.
