Why Lawstronaut for Brazilian legal research
Brazilian legal information is spread across the federal statute portal, superior and federal courts, administrative and tax tribunals, competition and financial regulators, and ministry publications. 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 Brazil legal coverage
Brazil is a civil-law federation governed by the 1988 Federal Constitution. Federal legislation — leis complementares, leis ordinárias, decretos, and medidas provisórias — is published by the Presidência da República on the Planalto portal (planalto.gov.br/ccivil_03). Case law comes from the superior and federal courts and administrative tribunals: Lawstronaut's coverage includes decisions of the Superior Tribunal de Justiça, the Conselho Administrativo de Recursos Fiscais (CARF), the Turma Nacional de Uniformização, and the Tribunal de Justiça do Distrito Federal e dos Territórios. Regulatory and enforcement materials are drawn from bodies such as CADE, SUSEP, and the Receita Federal. Records are published in Portuguese.
Brazilian law moves quickly: new federal decrees and ordinary laws are published on an almost daily basis, administrative tribunals issue a continuous stream of acórdãos, and regulators update guidance and enforcement decisions throughout the year. Point-in-time data straight from the official source is what keeps a Brazilian legal research answer correct today.
