Sources: 9. Developments: 2. The Brazilian Supreme Federal Court (STF) is currently addressing jurisdictional disputes involving both state officials and legislative authority. The STF plenary is set to judge a request by Maranhão Governor Carlos Brandão to remove Minister Flávio Dino as the rapporteur for investigations involving the governor. The defense argues that investigations into state governors should be handled by the Superior Court of Justice (STJ) rather than the STF, as mandated by the Constitution, and further claims a lack of impartiality from Minister Dino. In a separate matter, the STF unanimously struck down a municipal law from São José do Rio Preto that attempted to regulate insurance company activities. The court reaffirmed that the federal government holds exclusive authority to legislate on insurance matters, a decision industry representatives say prevents regulatory fragmentation and ensures legal certainty. ## Timeline ### 2026-09-21: Brazil's Supreme Court rules on jurisdictional disputes The Brazilian Supreme Federal Court is ruling on key jurisdictional issues, including a request to remove a rapporteur in a governor's investigation and the invalidation of a municipal insurance law. 4 sources. https://clstr.news/cluster/brazils-supreme-court-rules-on-jurisdictional-disputes ### 2026-08-26: Brazil requires formal ratification for foreign judicial decisions Foreign court decisions require formal ratification in Brazil to be legally effective, a process overseen by the Superior Court of Justice that focuses on procedural requirements rather than case merits. 5 sources. https://clstr.news/cluster/brazil-requires-formal-ratification-for-foreign-judicial-decisions --- Cite as: Brazilian Supreme Court jurisdictional rulings.
