The process was reported by the minister . In his vote, he considered that the commission has the legitimacy to receive the documents. Despite authorizing the sharing of information, the TCU determined that the documents sent to the Senate maintain the confidentiality classification.

To reduce the risk of leakage, the Court recommended that all files sent to the commission receive watermarks indicating the confidential nature of the content. The measure seeks to preserve the so-called “chain of custody” of information and reinforce that documents cannot be publicly disclosed.

The rapporteur stated that the commission and congressmen who have access to the material are obliged to preserve the confidentiality of the information. Improper disclosure may result in legal liability, as provided for in the LAI (Access to Information Law).

The minister’s determination comes after the leak of messages seized by the Federal Police on the cell phone of Master’s founder, Daniel Vorcaro. The businessman’s intimate conversations with his then-girlfriend Martha Graeff were mocked by users, who also created montages with Vorcaro’s photo after his arrest.

Minister Gilmar Mendes, from (Supremo Tribunal Federal), that the exposure of conversations between Daniel Vorcaro and Martha Graeff is a “very serious violation of the right to privacy” and a “demonstration of institutional barbarity that transgresses all limits imposed by laws and the Constitution”.

The TCU’s authorization is based on article 71 of the Constitution, which establishes cooperation between the court and the National Congress in the exercise of oversight of public administration.

The Banco Master case has been followed by congressmen and regulatory authorities, which motivated the commission’s request to access data gathered by the court. The objective is to allow the Senate to evaluate the information.
