Overview

• STF President Edson Fachin scheduled a virtual plenary from Sept. 30 at 11:00 to Oct. 1 at 23:59 to consider Minister Luiz Fux’s injunction.
• Fux granted a request by Senate President Davi Alcolumbre to maintain each state’s current number of deputies for the 2026 election.
• The injunction cites the constitutional annuality rule and exceptional urgency as reasons to avoid last‑minute changes.
• Congress approved PLP 177/2023 to raise seats from 513 to 531, but President Luiz Inácio Lula da Silva vetoed the bill and the veto has not been voted.
• With the current apportionment preserved, any redistribution tied to recent population data is effectively pushed to 2030, a shift that would chiefly benefit northern and center‑western states.
