What’s Happening

Brazil's Supreme Federal Court (STF) became the center of a procedural dispute on Dec. 3, 2025, when Justice Gilmar Mendes ruled that only the prosecutor general has standing to request the impeachment of a sitting justice, and that opening any such process requires majority support within the Senate. The decision narrows the pathways for removing an STF justice and raises the bar for any impeachment petition to advance. It directly shapes the outlook for whether any Brazil STF justice is removed by impeachment before 2027, since petitions filed outside the prosecutor general's office would face immediate procedural rejection.

The ruling lands amid sustained friction between the STF and Brazil's Congress, where a bloc of lawmakers has pushed for greater oversight of the court following rulings on electoral eligibility and social media regulation. Under the 1988 Constitution, the Senate holds the authority to try justices for crimes of responsibility, but no sitting STF justice has been removed through impeachment since the court's modern configuration. Mendes' decision effectively channels future petitions through the prosecutor general's office, a procedural milestone that supporters of court oversight say could stall legislative efforts to advance removal proceedings.

Attention now turns to the Senate, where any impeachment request must secure a majority to proceed, and to the prosecutor general's office, which would need to file a formal request for the process to begin. With 2026 election-year politics expected to dominate the legislative calendar, the window for advancing a removal vote before 2027 is narrow. The question of whether any Brazil STF justice is removed by impeachment before 2027 therefore hinges on procedural steps that, under the new ruling, remain firmly in the hands of federal prosecutors rather than individual lawmakers.
