Overview
- The dispute began with a February 2026 access-to-information request by Curitiba councilor Guilherme Kilter for Senate entry and exit logs covering Feb. 1, 2019 onward that named Viviane Barci, Daniel Vorcaro and others.
- The Senate’s Ouvidoria and Service of Information denied the requests, citing Decree No. 7.724/2012 and the General Data Protection Law (LGPD) on the grounds that the records are personal and restricted.
- A federal court in Curitiba declined jurisdiction and sent the mandado de segurança to the Supreme Federal Court, where Minister Luiz Fux was assigned as relator and ordered the Senate to respond.
- The PGR filed a formal opinion on Thursday, Oct. 22, 2026, urging the STF to reject the petition because the petitioner did not prove a 'direito subjetivo líquido e certo' and because no forum-privileged authority took part in the denial.
- If the court follows the PGR’s reasoning the case could be dismissed on procedural and jurisdictional grounds, a decision that would shape how transparency requests to Congress are balanced with privacy and parliamentary confidentiality.
