Brazil's Supreme Court Plunges Into Crisis Over Banco Master Scandal Ahead of Presidential Election

On Wednesday, Brazilian Supreme Court Chief Justice Edson Fachin suspended conflicting orders from two of his fellow justices, halting a rapidly escalating power struggle that had seen the country's federal police chief removed and reinstated within 24 hours. The intervention canceled a scheduled plenary session—the first such cancellation since 2009—and centralized all inquiries involving sitting justices under Fachin's direct control. The judicial warfare has paralyzed the nation's highest court just weeks before the October 2026 presidential election, transforming a multibillion-reais bank fraud investigation into a constitutional crisis.[1]

The immediate trigger for Fachin's intervention was a unilateral ruling issued on Tuesday by Justice André Mendonça, a 2021 appointee of former President Jair Bolsonaro. Mendonça ordered the immediate removal of Federal Police Director-General Andrei Rodrigues and intelligence director Leandro Almada. In his ruling, Mendonça alleged that the police leadership had produced six illegal intelligence reports designed to monitor his activities and undermine his oversight of two politically sensitive investigations.[1][2]

The following morning, Justice Flávio Dino, a former justice minister appointed by incumbent President Luiz Inácio Lula da Silva, overruled Mendonça and restored the police officials to their posts. Dino accused Mendonça of acting without evidence in a case where he held a personal interest, citing an "equally real and immediate" risk of harm to ongoing police work. Hours later, Fachin suspended both rulings, keeping Rodrigues in office temporarily and giving the police chief 48 hours to provide information regarding the alleged surveillance.[1]

The internal court battle is the fallout of the collapse of Banco Master, a private financial institution liquidated by Brazil's Central Bank in late 2025. The ensuing federal police probe, dubbed Operation Compliance Zero, has become the country's most significant fraud investigation since the 2014 Lava Jato scandal. The inquiry has ensnared political figures across the spectrum, but the current crisis ignited on September 1, when Mendonça unsealed messages extracted from the cellphone of Daniel Vorcaro, the bank's former owner.[1][4][5]

The unsealed communications showed Vorcaro repeatedly asking a contact saved as "Alexandre de Moraes" for privileged information regarding the fraud investigation. The messages also detailed a 131 million reais ($24 million) legal contract signed between Banco Master and a law firm managed by Viviane Barci de Moraes, the wife of Supreme Court Justice Alexandre de Moraes. De Moraes, who gained national prominence for sentencing Jair Bolsonaro to a 27-year prison term in 2023, has denied any wrongdoing and maintained that his wife's firm provided legitimate legal services.[1][2][4]

In response to the leak, de Moraes requested a formal investigation into Mendonça on September 3, accusing his colleague of abuse of authority and administrative misconduct. De Moraes cited a federal police intelligence report that questioned Mendonça's impartiality, noting that Mendonça had held private meetings with Vorcaro prior to the banker's arrest. The escalating retaliation between the two justices prompted Fachin to remove de Moraes from his role overseeing a separate, sprawling inquiry into disinformation, transferring control of that case to the chief justice's office to prevent further conflicts of interest.[1]

The judicial crisis has spilled directly into the October presidential race, where Lula is running for reelection against Senator Flávio Bolsonaro. During Brazil's Independence Day celebrations on September 7, tens of thousands of opposition supporters rallied on Paulista Avenue in São Paulo. Demonstrators carried inflatable figures of Mendonça and demanded the impeachment of de Moraes. Addressing the crowd, Flávio Bolsonaro explicitly tied the court's actions to the executive branch, declaring, "Whoever votes for Lula votes for Alexandre de Moraes."[1]

President Lula addressed the escalating scandal on Wednesday, calling the Banco Master collapse "the greatest financial crime in Brazil's history." The president demanded that the entirety of the investigation be unsealed rather than weaponized through fragmented disclosures. "What is needed is more transparency, not selective leaks that affect the election," Lula stated, warning that the dispute was damaging the integrity of the electoral process.[1]

Legal scholars warn that the public weaponization of court orders is inflicting severe institutional damage. Felipe Recondo, co-founder of the judiciary news platform JOTA, noted that the justices are using their unilateral ruling powers to attack and defend themselves, bypassing established procedural norms. "The court's public image had already been eroding, and this case has made it worse," Recondo said, warning that the primary risk is a complete institutional breakdown within the judiciary.[1]

The resolution of the crisis may ultimately depend on the voters. Alongside the presidency, Brazilians will elect 54 of the 81 members of the Federal Senate in October. Under the Brazilian Constitution, the Senate holds the exclusive power to try impeachment cases against Supreme Court justices, requiring exactly 54 votes for removal. Analysts note that a decisive victory for the Bolsonaro coalition could result in the necessary supermajority to formally impeach de Moraes, while a Lula victory would likely insulate him.[1]

Chief Justice Fachin has scheduled an extraordinary plenary session for September 15. The full 11-member court will be forced to publicly review the intelligence report that triggered the crisis, rule on the prosecutor general's request to invalidate Mendonça's initial order, and determine the permanent fate of the federal police leadership.[1]
