Brazilian Supreme Court justices hold lifetime tenure subject to Senate impeachment by a two-thirds vote, creating a high procedural threshold that has repeatedly blocked removal efforts against Alexandre de Moraes. Multiple opposition impeachment requests have been filed through mid-2026, citing his rulings on social media, Bolsonaro-related cases, and institutional powers, yet Senate leadership has declined to advance them for a vote despite claims of sufficient signatures falling short of the required majority. Moraes has continued issuing decisions, including suspending legislation that could affect sentences, without institutional challenge sufficient to alter his position. Traders price the low probability of removal by the end of any near-term window around these structural barriers and the absence of broader congressional momentum.
