In a significant ruling, Minister André Mendonça of Brazil's Supreme Federal Court (STF) announced that Daniel Vorcaro, owner of Banco Master, is not obligated to appear before the mixed Parliamentary Inquiry Commission (CPI) investigating the INSS. The CPI had anticipated his testimony on Monday, the 23rd, asserting priority in hearing him over other congressional committees also wanting to interrogate him. This ruling marks a crucial development in the ongoing inquiry into the operations of INSS, indicating a shift in the proceedings regarding Vorcaro's involvement.

Vorcaro has expressed to close acquaintances his reluctance to attend the hearing despite the CPI's hopes for his presence. The president of the CPI, Senator Carlos Viana, remains optimistic about Vorcaro's attendance, especially after expressing gratitude towards Mendonça for facilitating his travel to Brasília. The decision is particularly pertinent as Vorcaro has been under house arrest since late November of the previous year, stemming from earlier legal troubles tied to the 'Compliance Zero' operation conducted by Brazil’s Federal Police, which adds another layer of complexity to his potential testimony.

As the CPI seeks to gather critical insights regarding the INSS, Vorcaro's absence could hinder the commission's efforts. His testimony is considered important due to his connections within the financial sector and the implications of his bank's dealings. The legal environment surrounding this case exemplifies the tensions between governmental oversight, individual rights, and the ongoing efforts to unravel alleged misconduct within Brazil's social security framework.
