São Paulo legal source types covered
São Paulo coverage currently centers on court decisions from the Tribunal de Justiça do Estado de São Paulo (TJSP). State legislation, regulatory materials, and legislative history can be added on request, and Brazilian federal materials are covered under the Brazil jurisdiction.
Case Law
Appellate decisions (acórdãos) of the Tribunal de Justiça do Estado de São Paulo (TJSP) across civil, criminal and public-law chambers — agravos, apelações, habeas corpus and related judgments — taken directly from the court's case-law search (esaj.tjsp.jus.br), each tied to its process number and official link.
Legislation & Regulations
São Paulo state legislation — the State Constitution of 1989, state laws (leis estaduais) and decrees published by the Assembleia Legislativa (ALESP) and in the Diário Oficial do Estado de São Paulo — available on request; Brazilian federal legislation is covered under the Brazil jurisdiction.
Legislative History
Bills (projetos de lei), committee materials and amendment records from the Assembleia Legislativa do Estado de São Paulo (ALESP), where available and on request, version by version, each tied to its source.
Regulatory Guidance & Enforcement
Administrative acts and resolutions from São Paulo state agencies and bodies, published in the state Official Gazette, available on request where a source is prioritized by the Lawstronaut team.

Why Lawstronaut for São Paulo legal research
São Paulo generates one of the largest bodies of case law in the world: the Tribunal de Justiça do Estado de São Paulo publishes vast volumes of acórdãos across dozens of chambers every year. For humans, that scale 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 Paulo legal coverage
São Paulo is Brazil's most populous state and operates within Brazil's civil-law system. Brazilian private, criminal and procedural law is codified at the federal level, while the state has its own Constitution (the Constituição do Estado de São Paulo, 1989), state laws enacted by the Assembleia Legislativa (ALESP), and acts published in the Diário Oficial do Estado de São Paulo. State case law comes from the Tribunal de Justiça do Estado de São Paulo (TJSP), the state's court of justice, whose appellate decisions (acórdãos) are published through the court's case-law search on esaj.tjsp.jus.br. Materials are published in Portuguese. Lawstronaut's current São Paulo corpus centers on TJSP case law, with state legislation and regulatory sources available on request.
São Paulo case law moves continuously: the TJSP issues large volumes of new decisions daily, and jurisprudential positions on consumer, contract, tax and criminal matters shift as panels rule. Federal reforms — from the Código de Processo Civil to the Lei Geral de Proteção de Dados (LGPD) — feed directly into how state courts decide. Point-in-time data straight from the source is what keeps a São Paulo legal research answer correct today.
