A case moves to the full court
On 1 September, Justice André Mendonça decided not to rule alone on the Banco Master investigation. He sent the case to the full 11-member Supreme Court plenary.
The plenary will review new Federal Police material. It includes messages between Justice Alexandre de Moraes and Daniel Vorcaro.
Mendonça also lifted secrecy on the police report.
What is Brazil’s Supreme Court?
Brazil’s Supreme Court, known as STF, is the country’s highest judicial body. It has 11 justices, nominated by the president and confirmed by the Senate, serving until mandatory retirement at 75.
The plenary is the full bench, where all justices sit together. This case will be heard there, not by a single justice, which is unusual for a case involving a fellow justice.
Who are the key figures?
Justice Alexandre de Moraes is a former justice minister and a polarizing figure. He has led investigations into anti-democratic protests and is often criticized by the right.
Justice André Mendonça, appointed by former President Jair Bolsonaro, is the rapporteur for the Banco Master case. He chose to involve the whole court rather than decide alone.
Daniel Vorcaro owned Banco Master. The Central Bank liquidated it on 17 November 2025.
He is detained, awaiting trial, not convicted.
The messages at the center
A Federal Police report unsealed by Justice Mendonça shows Vorcaro messaged ‘Alexandre de Moraes BRASILIA’. Two days before arrest, he asked about leaving the country, per Folha.
Moraes has not publicly addressed the content of the messages. Poder360 said he did not respond to requests for comment.
On 3 September, Moraes asked the court to investigate Mendonça for administrative impropriety and abuse of authority. He cited the same police reports, which he says show Mendonça steered investigations against STF justices.
Fachin steps in and sets dates
On 3 September court president Edson Fachin ordered four officials to report within five days. They were Moraes, Mendonca, Prosecutor-General Paulo Gonet and Federal Police chief Andrei Rodrigues.
Fachin set the timetable on 5 September, per Poder360. Banco Master material reaches justices from 14 September; Moraes’s complaint against Mendonça starts 22 September.
The Federal Police itself stated that its intelligence reports on Mendonça have no evidentiary value. The reports have been criticized on technical grounds.
What happens next?
The plenary session will be public and in-person, but no specific day has been fixed. Court president Edson Fachin is responsible for scheduling, according to Mendonça’s decision.
The court has not published an agenda. It has not said what it may decide.
Independence Day protests
On 7 September, Brazil’s Independence Day, right-wing groups protested in 15 cities. The largest, in São Paulo, was led by Senator Flávio Bolsonaro.
Minas Gerais governor Romeu Zema led an act on Paulista at 9.20am. Goiás governor Ronaldo Caiado spoke at a parade in Goiânia.
The left-wing counter-mobilization is the traditional ‘Grito dos Excluídos’ at Praça da Sé in São Paulo from 7am. Popular movements, pastoral bodies and unions run it.
Lula’s address and sovereignty
On Sunday night, President Luiz Inácio Lula da Silva gave a three-and-a-half-minute address broadcast on national radio and television. He said Brazil ‘is not a colony and will not be anyone’s colony,’ as reported by Agência Brasil.
He also said that ‘no foreign ruler has the right to say who we can buy from. The address was authorized by the electoral court on 4 September.
Justices skip the parade
None of the eleven justices attended Monday’s military parade in Brasília. The four closest to the government — Moraes, Gilmar Mendes, Flávio Dino and Cristiano Zanin — stayed away, according to Brasilemfolhas.
Lula attended the parade but made no speech at the ceremony. His address was the previous night’s broadcast.
The role of the court president
Edson Fachin is the president of the Supreme Court. He is responsible for scheduling plenary sessions, according to Mendonça’s decision.
Fachin has set the windows for the cases. The Banco Master material will be examined from 14 September, and the Moraes complaint from 22 September.
The Federal Police report
The Federal Police sent the Supreme Court a report on Banco Master. It includes messages between Vorcaro and a contact saved as ‘Alexandre de Moraes BRASILIA’.
The police say the report has no evidentiary value. It has been criticized on technical grounds, according to Poder360.
Vorcaro’s arrest and bank
Daniel Vorcaro owned Banco Master, a mid-sized bank. The Central Bank liquidated it on 17 November 2025.
He is in preventive detention, awaiting trial. He has not been convicted of any crime.
Moraes’s complaint
On 3 September, Justice Alexandre de Moraes asked the court to investigate Mendonça. He cited the same police reports, alleging abuse of authority.
Moraes has not publicly commented on the messages. Poder360 said he did not respond to requests for comment.
What the plenary may decide
The full court could decide whether Moraes should step aside from cases involving Vorcaro. It could also open an ethics investigation.
No agenda has been published. The court has not said what it may decide.
Who is Daniel Vorcaro?
Daniel Vorcaro ran Banco Master, a mid-sized Brazilian bank. The Central Bank shut it down on 17 November 2025.
He is in jail awaiting trial, but has not been convicted. Police suspect fraud and financial crimes at the bank.
What the messages show
Federal Police found chats where Vorcaro asked a contact saved as ‘Alexandre de Moraes BRASILIA’ if he should leave Brazil. That was two days before his arrest, as Folha de S.Paulo reported.
Moraes has not commented on the chats. Poder360 says he did not answer their questions.
Why the plenary is important
A single justice usually handles a case. Sending it to all 11 justices makes the decision final and harder to challenge.
This case questions whether a justice can be impartial. The full court will now judge that.
What the court president does
Edson Fachin leads the Supreme Court. He decides when the full bench meets.
He has set windows for the justices to review the case from 14 September. No exact date is set yet.
Why the full court matters
When a case goes to the plenary, all justices hear it together. This adds weight and makes the decision final, unlike a single justice’s ruling.
The case touches on the independence of the Supreme Court. A justice talking to a bank owner under investigation raises questions about impartiality.
