The President of Brazil's Supreme Federal Court (STF), Justice Edson Fachin, has moved to contain an unprecedented public crisis within the country’s highest judicial body, removing a request for investigation filed by Justice Alexandre de Moraes against his colleague, Justice André Mendonça, from the original case files. The decision isolates the escalating internal conflict, which has been driven by a series of aggressive public maneuvers by both sides, into a new, separate procedure that Fachin will oversee directly. The intervention is a clear attempt to de-escalate a dispute that has been a significant driver of political risk in Brasília and threatened the court's institutional stability.
