Lula's re-election on October 25, 2026, has strengthened his negotiating position for filling the long-vacant STF seat left by Luís Roberto Barroso's 2025 retirement. Recent reporting highlights active talks with Senate President Davi Alcolumbre to advance a nomination, potentially of former Senate President Rodrigo Pacheco, in November before the new legislative session begins in February 2027. This timing aims to avoid a more conservative Senate bloc. Lula's earlier nomination of Jorge Messias was rejected by the Senate in April 2026, marking the first such defeat in over a century. Additional STF vacancies are expected through 2030 due to compulsory retirements of ministers including Luiz Fux, Cármen Lúcia, and Gilmar Mendes. These dynamics, combined with Lula's mandate to shape the court, center trader attention on near-term announcement prospects amid Senate confirmation requirements.
