Brazil’s Supreme Court canceled two consecutive sessions on September 11, 2026, as justices clashed over allegations of corruption and political bias, deepening a crisis that threatens the country’s presidential election. The turmoil stems from a dispute between Justice Andre Mendonca and Alexandre de Moraes, fueled by documents linking a disgraced banker to court proceedings.
The Brazilian Supreme Court’s abrupt cancellation of two straight days of deliberations on September 11, 2026, marked an unprecedented escalation in a political crisis engulfing the judiciary. The move came after Justice Andre Mendonca, an openly evangelical appointee of former President Jair Bolsonaro, publicly disclosed federal police documents suggesting Justice Alexandre de Moraes had advised a disgraced banker, Daniel Vorcaro, during a multibillion-dollar fraud investigation. The fallout has threatened to destabilize the October 4 presidential election, with both incumbent President Luiz Inacio Lula da Silva and Bolsonaro’s son, Flavio Bolsonaro, calling for investigations into the court’s integrity.
Justices Clash Over Banker’s Documents
The conflict erupted after Mendonca, a Bolsonaro appointee, unsealed messages between Vorcaro and de Moraes, a high-profile justice known for overseeing the trial of former President Bolsonaro over a coup plot. De Moraes, who has been a target of right-wing criticism for enforcing social media bans, accused Mendonca of abusing his authority to advance political goals. The revelations triggered a court-wide crisis, with 10 justices set to debate whether de Moraes should face an investigation over the messages.
The documents contain approximately 30 text exchanges between Vorcaro and a number linked to de Moraes. Vorcaro, the head of Banco Master, was arrested in November 2025 for defrauding investors of more than $7bn, one of Brazil’s largest banking scandals. The case has drawn scrutiny from lawmakers across the political spectrum, with Senator Flavio Bolsonaro himself implicated in a separate probe over film funding allegations.
Election Tensions Amid Judicial Crisis
The judicial turmoil has intensified as Brazil approaches its pivotal October 4 election. Mendonca, the court’s only openly evangelical justice, has emerged as a key figure for right-wing voters, with rallies in São Paulo featuring a giant balloon of his likeness. His recent ruling to suspend Lula’s federal police chief over an intelligence report alleging misconduct against him has further deepened divisions. The move drew criticism from Justice Flavio Dino, a Lula appointee, who warned against actions that could fuel political advertising, rallies, campaign events, or other forms of partisan political instrumentalization.
Reuters reported that Mendonca’s actions have alarmed officials in the Federal Police and prosecutor general’s office, who allege his rulings are part of a broader effort to unseat Lula and steer the court toward conservative positions. While Mendonca’s allies deny the accusations, describing him as an independent justice, the crisis has exposed fractures within the court. Chief Justice Luiz Edson Fachin, who halted sessions to allow justices to respond to allegations, faces pressure to restore order amid growing public unrest.
The Evangelical Justice Shaping Brazil’s Future
The justice’s involvement in the Banco Master scandal has drawn sharp criticism. Reuters cited officials who described his decisions as part of an effort to unseat Lula and steer the court toward conservative positions.
Mendonca, however, has remained silent on the allegations, declining to comment for the article.
What Comes Next for Brazil’s Democracy?
The crisis has left the Supreme Court in disarray, with its ability to function under strain. The court’s next session, scheduled for Tuesday, will determine whether de Moraes faces an investigation, a decision that could further polarize an already divided nation. Meanwhile, the Banco Master scandal continues to unfold, with police raids targeting figures linked to a film about Bolsonaro’s father, including Senator Flavio Bolsonaro.
For voters, the turmoil underscores the fragility of Brazil’s democratic institutions. With the presidential race tightening, the judiciary’s role in shaping the outcome has become a flashpoint. As one rally attendee prayed for Mendonca’s “courage,” the court’s internal conflicts risk becoming a defining chapter in Brazil’s political history. The coming weeks will reveal whether the judiciary can navigate this crisis or if the nation’s democracy will face further upheaval.
