Rule Changes

Issued multiple campaign rulings October 1-3, 2026; closed a preliminary inquiry into Bolsonaro's running mate on October 6

On October 25, the runoff day, Justice Cristiano Zanin of the Supreme Federal Court (STF) extended voting by two hours, to 7 p.m., at polling stations across Brazil. The move followed requests from the Lula and Flávio Bolsonaro campaigns and criticism that TSE president Kassio Nunes Marques had not acted on the problems reported. The TSE paused vote counting during the delay and then called an emergency meeting, where other justices criticized both the delay and Zanin's decision.
