An open conflict between two Supreme Federal Court (STF) Justices over the command of the Federal Police (PF) has prompted an extraordinary public intervention from Brazil’s powerful business community, warning that the institutional crisis threatens the country’s development and integrity. Justice Flávio Dino on Wednesday reversed an order by Justice André Mendonça, immediately reinstating PF Director-General Andrei Rodrigues just one day after Mendonça had ordered his removal. The back-and-forth over the nation’s top law enforcement official signals an escalating instability in the judiciary, the highest court responsible for safeguarding Brazil’s Constitution.
