Brazil's Supreme Court president Edson Fachin stepped in on Wednesday to suspend a cascade of conflicting rulings issued by rival justices, as an internal feud over a major banking scandal threatens to overshadow the country's upcoming presidential election. At the heart of the dispute are alleged text messages between fraud-accused banker Daniel Vorcaro — whose private lender Banco Master collapsed under billions in debt — and prominent Justice Alexandre de Moraes, sparking a bitter standoff between Moraes and fellow Justice André Mendonça, a Bolsonaro appointee, that even led to the brief suspension of Brazil's federal police chief. The crisis has alarmed the Brazilian business community, with some 3,000 organisations signing a manifesto warning of an "extremely serious institutional crisis" as candidates prepare for next month's presidential race, in which Flávio Bolsonaro, son of jailed former president Jair Bolsonaro, is seeking to unseat left-wing incumbent Luiz Inácio Lula da Silva.
