Brazil's Supreme Federal Court (STF) justices face significant structural barriers to impeachment, including a required two-thirds Senate majority for conviction and standing typically limited to the Prosecutor-General following recent rulings. No STF justice has ever been removed through this process, and current congressional dynamics—with the executive's legislative allies providing a reliable buffer—have historically led to the shelving of numerous petitions. Recent congressional inquiries into specific justices, including recommendations tied to financial scandals, have advanced no further due to procedural requirements and institutional protections. While U.S. sanctions on certain members and ongoing tensions with Congress have heightened scrutiny, these factors have not shifted the balance toward removal. Realistic scenarios altering the outcome before 2027 would require a major realignment in Senate support or an unprecedented cross-party consensus on specific allegations.
