The debate over the impeachment of Supreme Federal Court (STF) justices gained traction in the election campaign following statements by dean Gilmar Mendes. The magistrate stated that candidates who adopt this platform will face immense difficulties if they reach the Senate.

The Supreme Court's reaction and the scenario for 2027

The STF's resistance to the goal of achieving a majority in the Senate and scheduling the impeachment of magistrates gained strength during the election campaign. Led by Gilmar Mendes, the movement became more explicit when the justice said he does not fear candidates with this platform, though he predicted barriers to making it a reality.

A day earlier, the president of the STF, Justice Edson Fachin, classified the denunciation of abuses by politicians as populism and a threat to institutions. The speeches expose the clash of stances expected to mark the year 2027.

The legal battle over the Impeachment Law

Gilmar decided to act proactively and triggered the battle against the removal of justices by suspending provisions of the 1950 Impeachment Law and reinterpreting points of the procedure. The injunction initially restricted the filing of complaints to the Prosecutor General's Office and established a two-thirds quorum for admissibility in the Senate.

Following backlash, the justice partially backtracked, restoring the right of citizens to file petitions. The decision sparked controversy over the limits between the branches of government, with critics pointing to an institutional conflict.

The right wing's strategy and the choice in the Senate

The strategy of right-wing candidates to occupy the Senate has become central to the institutional clash. Presidential hopeful Flávio Bolsonaro publicized his support for candidates aligned with the impeachment of STF justices, with a special focus on Alexandre de Moraes.

In addition to the election of senators, the presidency of the chamber holds decisive power over the processing of complaints. For this reason, the choice of Davi Alcolumbre's successor in February 2027 will be a strategic step following the October elections.

The impact of the scandal and public opinion

Public perception of the Supreme Court has undergone a radical change, and the STF has come to be poorly rated regardless of the voter's political leaning. The Banco Master scandal directly hit justices of the Court, such as Dias Toffoli and Alexandre de Moraes, generating distinct internal consequences and stirring up the institutional backstage.
