Minister Alexandre de Moraes of the Supreme Federal Court (STF) has requested the court's president, Edson Fachin, to investigate André Mendonça. Moraes alleges abuse of authority, administrative impropriety, and crime of responsibility in the handling of cases involving Banco Master and the National Institute of Social Security (INSS).

According to a report by Folha de S.Paulo, the request for investigation was formalized on March 3, 2026, and follows the release of messages related to Daniel Vorcaro, which captured interactions among STF ministers. The details regarding these messages have been affecting the current political and judicial context.

Furthermore, UOL reported that the crisis involving the STF has intensified with these revelations, leading to discussions about the implications this situation may have on ongoing investigations. Journalists Thais Bilenky and José Roberto de Toledo commented on the repercussions during the program A Hora on Canal UOL.

The focus of the investigation proposed by Moraes aims to clarify Mendonça's conduct, reigniting debates about ethics and responsibility among court members. There is no information on how this request will be handled by Fachin or what steps will follow regarding this matter.

Recent developments highlight the complex relationships among STF ministers and external interferences, especially in light of the communications with Vorcaro, which have resulted in a tense environment within the institution.
