Investigations initiated by the Brazilian Supreme Court (STF) against officials from the Revenue Service have escalated tensions and suspicions between the court's ministers and segments of President Luiz Inácio Lula da Silva's administration. The STF suspects they may have been subjected to illegal investigations by the Revenue Service and the Federal Police. This situation has led to a climate of unease, as the investigators fear becoming scapegoats in the ongoing controversy, which is linked to the Banco Master case.

Following a directive from STF Minister Alexandre de Moraes to track tax data access for approximately 140 individuals—including family members of the judges—concerns arose among court members regarding whether clandestine information was utilized to fuel the Federal Police's investigations. Although the suspicion does not extend to the upper echelons of Lula's government, there is distrust that Revenue Service auditors might have unlawfully shared confidential tax data of judges and their relatives without prior approval from the court.

The implications of this investigation are profound, as they could impact the working relationships between the judiciary and the executive branches of government. These tensions may hinder collaboration and transparency necessary for effective governance. The situation remains fluid, with both the STF and the governmental sectors needing to navigate these allegations carefully to ensure the integrity of their respective institutions and the trust of the Brazilian public.
