The president of Brazil’s Supreme Federal Court (STF), Justice Edson Fachin, has intervened to halt an escalating internal power struggle between justices, centralizing decisions related to the fallout of the high-profile “Caso Master” scandal and scheduling an extraordinary session to restore institutional order. Justice Fachin, who is the head of Brazil’s top constitutional court, took action to suspend conflicting decisions made by Justices André Mendonça and Flávio Dino regarding the leadership of the Federal Police, thereby stabilizing the command of the key law enforcement agency. The move is designed to transition a personalized fight between justices into a collective, institutional decision by the full 11-member court.
