Brazil's Supreme Court has been engulfed in a public crisis after a heated, livestreamed confrontation between Justices Alexandre de Moraes and André Mendonça. The clash coincides with the Banco Master scandal — an investigation tying banker Daniel Vorcaro to prominent political and judicial figures — and has raised concerns the turmoil could influence a tight presidential race that may go to a run-off on 25 October. Legal experts warn the timing could create a "perfect storm" for Brazilian democracy as inquiries and counter-accusations unfold.
Brazil’s Supreme Court Implodes Days Before Presidential Vote as Banco Master Scandal Deepens

Brazil's Supreme Court has been plunged into its deepest institutional crisis since the return of democracy in the 1980s after a public, bitter confrontation between Justices Alexandre de Moraes and André Mendonça. The clash — livestreamed into millions of homes — unfolded as allegations tied to the Banco Master banking scandal implicated figures across Brazil's political and judicial elite, raising fears the turmoil could shape a knife-edge presidential race.
What Happened in Court
During a stormy hearing on Tuesday, the two justices traded sharp accusations and insults. Moraes accused Mendonça: "You're at the service of a political group that tried to launch a coup in this country!" Mendonça replied: "It's a lie!" Moments later, Justice Gilmar Mendes joined the exchange, accusing Mendonça of weaponizing court procedures to create political chaos. The heated exchange laid bare deep personal and political divisions on the 11-member court.
Banco Master: The Scandal at the Center
The crisis has surged in parallel with the Banco Master investigation. The bank's owner, Daniel Vorcaro, was arrested last November as he prepared to fly from São Paulo to Malta. Police say probes revealed apparent links between Vorcaro and an array of prominent figures, including Flávio Bolsonaro and, allegedly, connections to Justice Moraes and relatives of other justices.
Earlier this month, Mendonça unsealed a police dossier tied to that probe that reportedly contains WhatsApp exchanges purportedly between Vorcaro and Moraes, and a copy of a $25 million contract between Banco Master and the law firm of Moraes's wife. In one message, sent two days before Vorcaro's arrest, he allegedly asked Moraes: "Do you think … I need to get out [of the country]?"
Accusations, Counterclaims and Political Stakes
Mendonça has been accused of fast-tracking an inquiry into Moraes while slowing probes into Vorcaro's alleged ties to the Bolsonaros and his reported financing of a film about Jair Bolsonaro. Moraes denies wrongdoing, calling the charges politically motivated "criminal lies" and alleging the attacks are a revenge campaign by rightwing forces tied to the January 2023 Brasília riots. He also warned the smear effort involved "external actors" and could amount to foreign interference in Brazil's election.
The turmoil has clear political overtones. Moraes — a former prosecutor who successfully pursued charges related to the attempted coup by Jair Bolsonaro's supporters — is widely associated in the public mind with leftwing President Luiz Inácio Lula da Silva. Mendonça was appointed during Jair Bolsonaro's presidency and is viewed by critics on the left as sympathetic to the former president and his allies. With less than three weeks to go before voting, the dispute risks altering the tone and trajectory of a tight contest.
What Comes Next
On Tuesday, Supreme Court justices met in Brasília to consider whether to open an investigation into Moraes's conduct; Moraes himself has requested an inquiry into Mendonça. Observers warn this legal and political maelstrom could accelerate negative campaigning and deepen public mistrust in institutions just as polls point to a likely run-off between Lula and Flávio Bolsonaro on 25 October.
"The timing is awful," said Eloísa Machado, a constitutional law professor. "We are just a few weeks away from elections that already look to be challenging for a democracy that has been struggling to deal with extremist and anti-democratic groups. We have a perfect storm here."
Why It Matters
The episode matters not only because it involves allegations against sitting justices, but because it plays out at a decisive juncture for Brazil's democracy. The combination of explosive allegations, public courtroom fights and withering political rhetoric could shift voter perceptions, complicate the judiciary's role in election disputes, and invite international scrutiny if claims of foreign interference persist.
"This campaign is going to get dirtier much faster than we had expected," political analyst Thomas Traumann warned.
