Brazil's federal prosecution office, the PGR, said on Monday (14) that it favors lifting the secrecy on Banco Master payment records, backing a request by Supreme Court Justice Alexandre de Moraes one day before a full-bench session set for Tuesday (15). The filing was signed by Deputy Attorney General Hindemburgo Chateaubriand and sent to Chief Justice Edson Fachin.
According to Folha de S.Paulo, the records are detailed in a report by the Coaf, Brazil's financial intelligence council. The seal should come off, the deputy attorney general wrote, because the document is "relevant for a justice of this court to understand the full range of factors involved in the matter to be debated." The PGR also noted that the case files were not visible to the prosecution office.
Moraes made the original request in a petition to Fachin on Sunday (13). He asked that the secrecy be lifted on PET 15645, an inquiry assigned by prevention to Justice André Mendonça, who oversees the Master case, on the argument that it holds "essential elements" for the judgment of PET 16662, scheduled for Tuesday. "I ask Your Excellency to order the lifting of the secrecy of PET 15645 and to make the records available to all members of the panel before the judgment," the justice wrote, according to G1. Fachin then asked the PGR to weigh in "promptly."
The case and Tuesday's session
The fight over the records is part of the crisis the Master investigations have opened at the STF, Brazil's top court. According to G1, federal police found 52 messages exchanged between Moraes and former banker Daniel Vorcaro, the owner of Master, between December 21, 2023 and November 17, 2025, the day Vorcaro was first arrested. The federal police report, ordered by Mendonça, points to an alleged relationship between the two and states that the justice took part directly in reviewing and editing a 130 million reais contract between the bank and the Barci de Moraes law firm of lawyer Viviane Barci, Moraes' wife. No formal investigation has been opened against the justice; the full bench will decide whether the material justifies that step.
The PGR has separately asked the court to shelve the federal police report. In the office's view, Mendonça ordered its production without notifying the court presidency, without submitting it to the full bench and with alleged targeting, a defect that would taint the report at its origin. Back in March, Folha reports, the federal police itself had asked Mendonça for access to the confidential financial intelligence data, still unexamined by the rapporteur, to map the Master payment system and funds linked to the bank.
The next step comes on Tuesday (15), when the full bench takes up PET 16662. If the justices accept the defect argument pressed by the PGR, the substance of the messages may never be discussed. If they reject it, the court will then decide whether the exchanges justify opening an investigation into Moraes.
