Quick Summary
The investigation into Banco Master has reached the highest levels of Brazil's judiciary, creating a complex procedural scenario. At the center is Justice Dias Toffoli, who currently holds the case.
However, a specific legal mechanism exists that could shift the investigation's trajectory. Four other justices of the Supremo Tribunal Federal (STF) possess the authority to question this assignment, potentially moving the case to a collective deliberation body.
The Procedural Mechanism
The Segunda Turma (Second Chamber) of the STF is the collegiate body responsible for deliberating on this specific case. Justice Toffoli is a member of this chamber, alongside four other ministers who hold significant procedural power regarding this investigation.
According to court regulations, any minister within this chamber can, on their own initiative, raise a doubt regarding the STF's competence in the case. This action is a formal legal tool available to the judiciary.
The ministers who share this authority with Toffoli are:
- Gilmar Mendes
- Luiz Fux
- André Mendonça
- Kassio Nunes Marques
For this procedural challenge to occur, Justice Toffoli must first remit the case to the Segunda Turma. His historical approach, however, has often favored monocráticas (single-justice) decisions.

The Case Background
The Banco Master investigation entered the Supreme Court's purview due to the involvement of Deputy João Carlos Bacelar of the PL party from Bahia. The case centers on allegations of banking fraud.
Significantly, the Polícia Federal (PF) has stated that the deputy is not the target of this specific investigation. Furthermore, his name has not been included in any related operations to date.
The physical presence of the bank is located in the Itaim Bibi neighborhood, situated in the Zona Sul of São Paulo. The investigation's focus remains on the alleged fraudulent activities associated with the financial institution.

This internal perspective suggests that shifting the case to the full chamber is viewed by some as a method to diffuse intense public scrutiny currently focused on the individual justice and the court itself.
Stakeholder Positions
While the procedural path exists, the willingness of the involved parties to pursue it varies. The Ministério Público (MP) and the defense attorneys for the involved parties also possess the ability to raise the question of competence.
Despite having this option, the legal defenses have reportedly shown no interest in removing the case from the STF's current handling. This lack of movement from the legal teams suggests a strategic preference for the status quo.
The dynamic creates a unique standoff:
- The procedural power lies with the four ministers
- The physical case file remains with Justice Toffoli
- The external parties have not yet requested a transfer
The decision ultimately rests on whether the ministers choose to exercise their prerogative or if the case proceeds through Toffoli's singular jurisdiction.
Judicial Context
Justice Dias Toffoli has a documented history of issuing monocráticas decisions. A notable example cited is his ruling to forgive million-dollar fines related to the Lava Jato operation.
This tendency toward individual rulings contrasts with the collective nature of the Segunda Turma. The current Banco Master case presents a scenario where the collective body may need to assert its role.
The involvement of high-profile ministers like Gilmar Mendes and Luiz Fux adds weight to the potential for a chamber-wide deliberation. The court's internal mechanisms are designed to handle such conflicts of competence.
The location of the bank in Itaim Bibi and the connection to a federal deputy from Bahia adds layers of political and regional complexity to the legal proceedings.
Looking Ahead
The Banco Master investigation sits at a procedural crossroads within Brazil's highest court. The existence of the Segunda Turma mechanism provides a clear, legal path for a potential shift in judicial oversight.
Whether the four ministers—Mendes, Fux, Mendonça, and Nunes Marques—choose to invoke their authority remains the central question. Their decision will determine if the case remains a singular responsibility or becomes a collective judicial effort.
Observers of the STF will be watching closely for any procedural motions that signal a change in the case's handling. The outcome will likely influence how similar high-profile investigations are managed within the court in the future.
