(FILES) (FILES) Brazil's Federal Supreme Court (STF) minister Alexandre de Moraes speaks with his wife Viviane Barci de Moraes during a ceremony where Judge Edson Fachin took office as Chief Justice and Moraes as Deputy Chief Justice, in Brasilia on September 29, 2025. Two Brazilian Supreme Court judges are at the center of an unprecedented clash that is shaking the country's highest judicial institution on the eve of the October presidential election. On one side is Alexandre de Moraes, considered by the right as the bane of the Bolsonaro movement; on the other is Andre Mendonca, appointed by Jair Bolsonaro himself. The two judges will face off in a session broadcast on national television. (Photo by Evaristo Sa / AFP via Getty Images)
