STF President Fachin Demands Full Police Files on Caso Master Scandal

The president of Brazil’s Supreme Court (STF), Justice Edson Fachin, has formally demanded that the Federal Police hand over complete, unredacted files regarding any members of the high court implicated in the "Caso Master" corruption probe. In an official letter sent on Friday, October 2, 2026, to Federal Police Director-General Andrei Rodrigues, Fachin asserted that there is an "unequivocal institutional interest" in ensuring every relevant fact is rigorously investigated, "without exception of any nature".

The move escalates a major institutional crisis within Brazil’s highest judicial body. The controversy centers on Daniel Vorcaro, the jailed former owner of Banco Master, whose seized phone messages allegedly implicate multiple high-ranking political and judicial figures. Recent leaks and the partial lifting of secrecy by investigator Justice André Mendonça have revealed messages linking Vorcaro to people associated with several sitting Supreme Court ministers, including Alexandre de Moraes, Dias Toffoli, Luiz Fux, and Kassio Nunes Marques.

To coordinate the next steps of the sensitive inquiry, Fachin has scheduled a high-level, face-to-face meeting with Federal Police Chief Andrei Rodrigues on October 13, 2026. The meeting was requested by the police chief to discuss how to handle the highly sensitive evidence involving members of the court. Fachin emphasized that once his office receives the full, unredacted reports, he will take all necessary legal steps, while ensuring that the police, prosecutors, and the judiciary respect their respective constitutional boundaries.

This domestic crisis strikes at a highly sensitive time for the STF Brasil presidente and the wider judiciary, as the country navigates a polarized political environment ahead of the next presidential election. For foreign observers asking does brazil have a president capable of keeping institutional peace, the Supreme Court's internal friction presents a test of stability. The court has faced intense public scrutiny in recent years, and the spectacle of its own members being named in a financial police probe threatens to erode public trust in the country's ultimate constitutional arbiter.
