The failure of Banco Master, Brazil’s largest bank failure on record, has pulled in courts, police and politicians in Brasília. Now the capital’s bar association has opened an ethics case reaching into a Supreme Court justice’s family.
The Brasília section of the OAB, Brazil’s national bar association, opened two ethics and disciplinary proceedings on 8 September 2026. One targets partners of a law firm that includes Viviane Barci de Moraes, wife of Supreme Court Justice Alexandre de Moraes.
Why This Matters
Alexandre de Moraes has sat on the Supreme Federal Court, Brazil’s highest court, since 2017, appointed by President Michel Temer. He was the rapporteur, or lead judge, in the case that convicted former president Jair Bolsonaro of a coup plot.
The court sentenced Bolsonaro on 11 September 2025 to 27 years and 3 months in prison. Washington placed Moraes and his wife under Magnitsky Act sanctions in 2025, then lifted them on 12 December 2025.
That history makes anything touching Moraes’s family politically charged, at home and abroad. The ethics case concerns Banco Master, a private bank the Central Bank shut down on 18 November 2025.
Poder360 puts the total loss at R$47.3 billion (US$9.3 billion), the largest bank failure in Brazil’s history. The deposit guarantee fund, known as FGC and financed by member banks, expected to pay about R$40.6 billion (US$8.0 billion).
Brazil votes for president on 4 October, with a possible runoff on 25 October. Incumbent Luiz Inácio Lula da Silva faces Senator Flávio Bolsonaro, the former president’s son, among other candidates.
Dollar figures use the Banco Central rate of R$5.0856 per US dollar for 8 September 2026. They are rounded, and they convert the real amounts exactly as reported in Brazil.
What Was Opened
The OAB, founded in 1930, registers and disciplines Brazil’s lawyers, who numbered over 1.2 million in 2021. Lawyers must register with it to practise, and regional sections such as Brasília’s handle discipline.
The Brasília section opened an ethics and disciplinary proceeding on 8 September against partners of a firm registered with it. The proceeding is directed at the partners, not at the firm as an entity.
A second, separate proceeding was opened the same day against lawyer Ciro Soares, CartaCapital and Metrópoles reported. The section’s president, Paulo Maurício Siqueira, opened both on his own initiative, without any outside complaint.
His stated basis was facts recently made public in a Federal Police report. According to Metrópoles, the review covers possible ethics breaches, conflicts of interest and improper solicitation of clients.
Who Is Named
Brazilian outlets report that the respondents include Viviane Barci de Moraes and two of the couple’s children. A sister-in-law and a fifth lawyer are also reported among them.
Those names appear in press accounts rather than in the bar’s own note, which lists nobody. There is a naming trap here that much coverage falls into.
The firm registered in Brasília, Barci & Barci Sociedade de Advogados, is not the São Paulo practice in the contract reports. That practice is Barci de Moraes Sociedade de Advogados, with a similar name and overlapping people, Metrópoles reported.
The Alleged Conduct
The subject is contracts between the family’s legal practice and Banco Master, controlled by banker Daniel Vorcaro. Columnist Malu Gaspar first reported the main contract in the newspaper O Globo on 9 December 2025, Poder360 says.
Brazilian outlets report it was signed in January 2024 and ran for 36 months. Poder360 put the monthly payment at about R$3.646 million (US$717,000) and the total near R$131.3 million (US$25.8 million).
It covered monitoring of government agencies, especially the Central Bank, and liaison with Congress and the courts, Poder360 reported. How much of the contract was actually paid is not known, the same outlet said.
A further contract with a company linked to Vorcaro is reported at R$50 million (US$9.8 million). Federal Police accuse Vorcaro of selling about R$12.2 billion (US$2.4 billion) in fake loan portfolios to BRB, a state-owned bank.
Vorcaro has been detained twice and remains in custody, but he has not been convicted. No finding has been made about the law firm’s contracts, and no one in the family has been charged.
What the Bar Actually Said
The bar’s note confirms only that two proceedings were opened, and that is its whole public statement. It says explicitly that opening them does not imply any prior judgment of guilt.
It also says the cases will observe due process and confidentiality. Those are standard protections in Brazilian disciplinary proceedings, and they keep the file out of public view.
The Response
The firm said the facts had already been examined and shelved by the prosecutor general’s office. It lamented their use in what it called an electoral context, less than four weeks before the vote.
It asked the bar section’s president to reconsider his public statements and clarify them. In December 2025, Moraes’s office said his wife’s firm never worked on the sale of Banco Master, Poder360 reported.
No new response from Justice Moraes to the bar’s decision has been reported. None from Viviane Barci de Moraes personally is on the record either.
Where This Sits in a Bigger Fight
The Banco Master affair has been running since 2025 and has reached almost every institution in Brasília. Justice Dias Toffoli gave up running the case at the Supreme Court on 12 February 2026 after criticism over a private-jet trip.
The securities regulator convicted Vorcaro and fifteen others in a separate administrative case on 8 September. The same week, a Supreme Court justice removed the Federal Police director-general over surveillance claims.
Eleven of the force’s fifteen directors then offered to give up their posts. Thirteen retired justices also wrote to the court’s president.
All of it is happening four weeks before a presidential election. That timing is now the argument every side makes about every other side.
How Disciplinary Proceedings Work in Brazil
A disciplinary proceeding is run by the bar association, not by a court, under Law 8,906 of 1994. It cannot impose a criminal penalty, and it does not decide whether a contract was lawful.
The law allows four sanctions, namely censure, suspension of 30 days to 12 months, expulsion from the profession and fines. Expulsion requires a two-thirds vote of the section’s council, and a censure cannot be publicised.
The process runs from opening to investigation, defence and a ruling by an ethics tribunal, and appeals follow. Cases routinely end without sanction, and an opening signals only that a question is worth asking.
What It Means If You Follow Brazil
For foreign observers, the case is a test of whether Brazilian institutions can scrutinise people close to the top court. The firm has already called the timing electoral, so the case is now part of the campaign debate.
For investors, the direct bank risk is already priced, since Banco Master has been in liquidation since November 2025. The larger risk is institutional, because every new leak feeds doubts about the courts during the campaign.
What Is Not Yet Known
It is not known how much of the reported contract was actually paid. It is not known when the ethics tribunal will rule, since the file is confidential.
The bar has not publicly named the respondents or the specific rules they allegedly broke. It is also unclear whether any other body will reopen the facts the firm says prosecutors shelved.
Frequently Asked Questions
Why does this ethics case matter?
It reaches the family of Alexandre de Moraes, the Supreme Court justice who led Bolsonaro’s coup trial. It also ties that family to Banco Master, Brazil’s largest bank failure.
Does this mean anyone has been found guilty?
No. The bar’s own note says opening the proceedings implies no prior judgment of guilt, and the cases are confidential.
Is Justice Alexandre de Moraes himself under investigation by the bar?
No. The proceeding concerns partners of a law firm, among them his wife, and the bar has no jurisdiction over a sitting justice.
What has the firm said?
It says the facts were already examined and shelved by the prosecutor general’s office. It also objects to their use in an election period.
