Key details
On September 10, 2026, Supreme Federal Court (STF) President Edson Fachin formally requested Minister André Mendonça to lift the secrecy surrounding the key investigations in the Banco Master case. Subsequently, Mendonça complied, unsealing the investigations while maintaining confidentiality for aspects deemed essential for ongoing proceedings. This move aims to enhance transparency within the controversial case involving former banker Daniel Vorcaro and messages linked to Minister Alexandre de Moraes.
Fachin’s request coincides with a scheduled plenary session set for September 15 to discuss a Federal Police report. The report includes communications sent by Vorcaro to a phone attributed to Moraes, stirring a major crisis within the STF. The session will also deliberate on whether to authorize investigations against Moraes, who faces allegations due to his ties with Vorcaro. Moraes, in turn, has called for probes into Fachin for alleged abuse of power and accused Mendonça of political bias in managing the Banco Master and INSS fraud inquiries.
According to Mendonça’s official order, lifting the confidentiality “is in harmony with the request” of Fachin, allowing STF members access to the related records. The decision not only covers the main investigation but also investigations involving the sale of credit portfolios by Banco Master to the Bank of Brasília. This step responds to growing pressures within the Court to handle allegations against Moraes and Mendonça simultaneously, lest procedural delays ensue.
The Attorney General, Jorge Messias, praised Fachin's initiative, underscoring transparency as fundamental to institutional integrity. Additionally, Senator Rogério Marinho has urged that similar openness extend to other contentious inquiries, including the politically charged fake news investigation overseen by Moraes.
This development marks a critical moment in Brazil's judicial-political landscape, as the STF grapples with internal divisions and public demands for clarity regarding the Banco Master case. The upcoming plenary session is anticipated to chart the next course of action amid mounting scrutiny of the Court's handling of these sensitive investigations.
