André Mendonça, a minister of Brazil's Supreme Federal Court (STF), is gaining attention as the Judiciary resumes its activities following the Carnival. Recently appointed as the rapporteur for the 'Master' case after the departure of Dias Toffoli, Mendonça is now overseeing two politically significant investigations in Brasília: one concerning the bank of Daniel Vorcaro and another related to frauds in the National Social Security Institute (INSS). This puts him in a crucial position within the Brazilian judicial landscape, especially as investigations can have far-reaching implications for political actors and governance.

On March 13, during a period of institutional conflict between the STF and the Federal Police (PF), Mendonça met with delegates and investigators to update himself on the Master investigation. The PF, which has been accused by STF ministers of pursuing investigations against Toffoli without the proper authorization, is expected to send Mendonça a report on the ongoing case in the coming days. The developments in this context are highly anticipated and suggest a point of tension between judicial independence and alleged external pressures.

As Mendonça prepares to signal how the Master case will proceed, there is speculation about what changes he may implement regarding its confidentiality or whether the case will be sent back to the lower courts. The outcome of these discussions could significantly impact not only the cases at hand but also the broader political atmosphere in Brazil, particularly concerning the interplay of power between the judiciary and law enforcement agencies.
