Case law · Brazil
Ask about Brazilian statutes, codes or superior-court decisions in everyday language. LexChat reasons only over the reported sources it retrieves and pins each answer to a citation you can inspect.
Why it holds up
Brazil is a civil-law jurisdiction with an enormous docket. Constitutional questions culminate in the Supremo Tribunal Federal, while the Superior Tribunal de Justica sits atop non-constitutional questions of federal law, above the regional federal courts and the state systems. With codes, federal statutes and layers of superior-court decisions to reconcile, finding the authority that actually settles a point is genuinely hard.
LexChat searches Brazilian sources first: reported decisions of the STF and STJ together with the country's legislation. It reasons only over what it retrieved, and every proposition in the answer is pinned to a citation you can open — so you can confirm the holding yourself instead of trusting a summary.
The court system
Brazil's constitutional apex court. The STF has the final word on the Federal Constitution, hearing concentrated constitutional challenges as well as extraordinary appeals raising constitutional questions from the lower courts.
The apex court for non-constitutional questions of federal law. The STJ hears special appeals from the regional federal courts and the state courts, keeping the interpretation of federal statutes uniform across the country.
The federal appellate tier, sitting above the federal trial judges and hearing appeals in cases involving the federal government and other matters assigned to the federal justice system.
Each state maintains its own courts of justice, where most Brazilian litigation begins and is decided. Their judgments can reach the STJ or the STF when federal-law or constitutional questions are at stake.
