Members of the high court have exchanged accusations after one justice was accused of involvement in a bank scandal.

Brazil’s Supreme Court has cancelled a second straight day of deliberations as suspicions of corruption, political bias and police interference loom over several of its members.

Cancellations are rare at the high court. But on Thursday, Chief Justice Luiz Edson Fachin nixed a second consecutive session, calling for the court to reconvene on Tuesday instead.

The decision was spurred by an ongoing crisis among the court’s members.

The divisions emerged on September 1, when one justice, Andre Mendonca, unsealed a series of federal police documents that appeared to show a disgraced banker, Daniel Vorcaro, seeking advice from another justice, Alexandre de Moraes.

De Moraes has rocketed to prominence in recent years for his roles in high-profile cases.

He presided over the trial of former President Jair Bolsonaro after prosecutors accused the far-right leader of plotting a coup following his 2022 election defeat. De Moraes also oversaw suspensions of platforms like X and Rumble for failing to abide by court orders, making him a target for Brazil’s right wing.

The document release authorised by Mendonca, a Bolsonaro appointee, contains roughly 30 text messages sent to a phone number associated with de Moraes, allegedly from Vorcaro.

In response, de Moraes has accused Mendonca of abusing his authority on the court for political gains. He requested a probe into whether Mendonca interviewed Vorcaro without the presence of police or prosecutors.

Tuesday’s session will involve the full Supreme Court bench, and 10 of the justices will discuss whether the 11th member, de Moraes, should be investigated over the text messages.

The tit-for-tat on Brazil’s high court is the latest fallout from the Banco Master corruption scandal.

Vorcaro, the head of the Banco Master financial institution, was arrested in November 2025 on accusations he defrauded investors of billions in lost funds, in one of the biggest banking scandals in the country’s history.

The collapse of Banco Master’s private banking arm left behind more than $7bn in debt.

Lawmakers from across the political spectrum have become embroiled in the unfolding scandal as new details emerge.

The turmoil risks affecting October’s general elections, including a pivotal presidential election.

Left-wing incumbent Lula Inacio Lula da Silva is set to compete for the presidency against Jair Bolsonaro’s eldest son, Senator Flavio Bolsonaro.

Both Lula and Senator Bolsonaro have called for investigations into the Supreme Court justices.

The Bolsonaro family itself has been dragged into the Banco Master scandal. In May, the publication Intercept Brasil released a report showing that Senator Bolsonaro petitioned Vorcaro for funds to finance a film about his ex-president father, who is now serving a 27-year prison sentence.

Senator Bolsonaro has denied wrongdoing, claiming he did nothing more than seek private sponsorship for the film, entitled Dark Horse.

But on Thursday, Brazilian police executed dozens of raids related to the Banco Master scandal, including some that targeted two figures involved in the film: Karina Gama, the head of a production company, and Congressman Mario Frias, who served as executive producer.

Senator Bolsonaro has called the probes “attempted political interference” ahead of the elections.
