Kléber Cabral, the president of Unafisco Nacional, has been summoned by Brazil's Federal Police as a result of his critical comments regarding an ongoing investigation aimed at auditors from the Receita Federal. This inquiry is focused on suspected leaks of confidential data related to ministers of the Supreme Court and their families. The summons was issued on March 20, 2023, following a decision from Supreme Court minister Alexandre de Moraes, although the precise reasons for Cabral's summons remain unclear, being speculated if it relates directly to his public statements.

During an interview with GloboNews, Cabral discussed the broader implications of the operation on the work of tax auditors, highlighting concerns that such measures serve to intimidate or threaten investigative professionals. He underscored the chilling effect on the willingness of auditors to pursue investigations against authorities, stating, "This type of measure seeks to humiliate, embarrass, and intimidate." His remarks suggest a significant tension between tax auditing roles and the political landscape, particularly concerning oversight of powerful officials.

This development raises questions regarding the independence of tax officials and the integrity of investigations into government conduct. The inquiries into data leaks not only reflect broader issues of governmental accountability but also pose risks to the conduct of regular oversight by the Receita Federal. As the situation unfolds, it remains to be seen how the government and judicial authorities will navigate these challenges and the potential fallout that could impact public trust in tax governance.
