Minister Dias Toffoli from Brazil's Supreme Federal Court (STF) has acknowledged that he is a partner in Maridt Participações, a family business run by his siblings that has engaged in transactions with Reag, a company linked to Banco Master. This relationship centers around the Tayayá luxury resort in Ribeirão Claro, Paraná, of which the Toffoli family was a part-owner until February of last year.

The investigations into this connection are part of a broader probe called Operation Compliance Zero, which aims to uncover alleged financial fraud schemes involving Banco Master. João Carlos Mansur, the founder and former executive of Reag Investimentos, is among those being investigated in connection with this operation, highlighting the serious allegations of misconduct linked to financial practices in Brazil's banking sector.

Toffoli's public acknowledgment comes in light of a recent report from the Federal Police concerning evidence collected from the mobile phone of Daniel Vorcaro, the owner of Banco Master. This report mentions Dias Toffoli and raises questions about his involvement and possible conflicts of interest as the lead investigator on the case against the bank, revealing the complexities within Brazil's political and financial landscape.
