Key details
Federal deputies from Brazil's Workers' Party (PT), Communist Party of Brazil (PCdoB), Socialism and Liberty Party (PSOL), and Rede Sustainability have formally called on the Supreme Federal Court (STF) President Edson Fachin to lift the secrecy surrounding the Dark Horse investigation involving Flávio Bolsonaro (PL-RJ). Their request comes amid concerns over political bias and transparency ahead of Brazil's upcoming presidential election.
The deputies' petition cites a report from ICL Notícias revealing a private meeting between Minister André Mendonça and financier Daniel Vorcaro in March 2025. They allege that Mendonça has demonstrated inconsistent approaches in handling politically sensitive investigations — publicizing probes involving Jaques Wagner (PT-BA) while keeping several procedures linked to Flávio Bolsonaro confidential. Such differential treatment, the deputies argue, unfairly benefits Bolsonaro by allowing control over the narrative and denying the public and media insight into ongoing investigations.
They point to a precedent wherein former STF rapporteur Dias Toffoli recused himself from the Master case due to his ties with Vorcaro, highlighting the need for similar transparency and impartiality from Mendonça. The deputies warn that continued secrecy could prompt them to file a formal motion questioning Mendonça's impartiality and urge that the matter be openly discussed in a public STF session.
This push for transparency reflects mounting political pressure on the STF to ensure fairness and uniform standards regarding the publicity of investigations involving presidential candidates. It also underscores growing unease about perceived favoritism in the judiciary just months before critical national elections.
The STF has yet to respond to the deputies' demands. Meanwhile, the issue raises broader questions about the balance between judicial secrecy and the public's right to information in politically charged investigations.
