Brazil’s Supreme Federal Court (STF) has been thrust into an unprecedented institutional crisis after revelations detailing alleged ties between one of its most powerful judges, Justice Alexandre de Moraes, and a disgraced banker, leading to a direct clash between two of the court’s members. The internal turmoil has significantly heightened political instability in Brasília, challenging perceptions of the judiciary's impartiality just weeks before general elections. The crisis centers on the sprawling federal investigation into the collapsed Banco Master and its former owner, Daniel Vorcaro.
