The Unresolved Scandal: Allegations of Unauthorized Access in Flávio Dino’s STF Cabinet Linger Without Investigation
By Hotspotnews
In the intricate web of Brazilian politics, where alliances shift and rivalries endure, a scandal emerged in early 2025 that spotlighted potential misconduct within the highest echelons of the judiciary. At its core was an accusation leveled against two assessors in the cabinet of Supreme Federal Court (STF) Minister Flávio Dino, alleging unauthorized accesses to sensitive state documents. Despite the gravity of the claims and formal complaints to top judicial authorities, the matter appears to have faded into obscurity, with no evident investigation or resolution as of March 2026. This case not only highlights ongoing political tensions in Maranhão but also raises questions about accountability in Brazil’s Supreme Court.
The Origin of the Allegations
The controversy began in February 2025, amid a heated political dispute in Maranhão, Dino’s home state and a battleground for influence between his allies and rivals. Dino, a former governor who ascended to the STF in 2023, has long been a polarizing figure, celebrated by supporters for his anti-corruption stance during the Lava Jato era and criticized by opponents for alleged overreach.
On February 20, 2025, two assessors from Dino’s STF cabinet—Túlio Simões Feitosa de Oliveira and Lucas Souza Pereira—allegedly accessed the Maranhão State Prosecutor’s Office internal system, known as the Sistema Eletrônico de Informações (SEI), approximately 130 times. These accesses were purportedly made from computers within the STF itself, according to a report from the state’s Technology Information Agency. Both men were on leave from their original positions at the Procuradoria Geral do Estado do Maranhão (PGE-MA) and had been seconded to Dino’s team.
The purpose? Critics claim the accesses were to gather documents supporting a lawsuit filed by the Solidariedade party—an ally of Dino’s political network—against Maranhão Governor Carlos Brandão. The suit accused Brandão of nepotism, specifically for failing to comply with STF orders to dismiss relatives from government posts. The accessed files reportedly included internal memos and evidence related to these nepotism cases, which were then allegedly leaked to bolster the legal action.
Valdênio Caminha (sometimes spelled Valdenio), the PGE-MA’s Procurador-Geral at the time, blew the whistle. In late March 2025, he sent a formal denunciation to STF Minister Alexandre de Moraes (the rapporteur for related cases) and Procurador-Geral da República Paulo Gonet, describing the accesses as possible criminal activity and a grave violation of information security norms. Caminha’s move was bold, given the political risks in a state still influenced by Dino’s network, and it framed the incident as potential judicial overreach to settle scores in Maranhão’s power struggles.
Denials and Counter-Accusations
The assessors swiftly denied any wrongdoing. Simões and Souza maintained that they only accessed publicly available documents for legitimate administrative purposes, acting independently and not under Dino’s direction. They emphasized their status as licensed PGE-MA prosecutors, retaining access rights to the SEI system. In statements, they dismissed the accusations as politically motivated smears amid the Brandão-Dino rivalry.
The fallout escalated into legal skirmishes. In April 2025, Souza filed a criminal interpellation against Caminha, claiming defamation for implying criminality. Caminha countered by calling it an intimidation tactic, and the dispute spilled into the Maranhão Court of Justice (TJMA) and back to the STF. Meanwhile, conservative commentators like former Lava Jato prosecutor Deltan Dallagnol amplified the story, portraying it as evidence of STF bias and calling for impeachment proceedings against Dino, citing his close ties to Gonet.
The Current Situation: A Scandal in Limbo
Fast forward to March 2026, and the scandal remains unresolved. There is no public record of the PGR launching a formal inquiry, nor has Moraes issued any ruling on Caminha’s request. Media coverage, which peaked in spring 2025, has largely dissipated, with no follow-up reports on indictments, charges, or even preliminary findings.
In June 2025, the PGE-MA responded indirectly by contracting a São Paulo-based firm to enhance SEI access controls with cryptographic tokens, suggesting internal reforms but no escalation against the assessors. By August 2025, Caminha himself was removed from his post by Moraes—not for his denunciation, but for failing to enforce STF nepotism rulings against Brandão’s administration. Fact-checks have debunked claims that this was retaliation, attributing it instead to procedural non-compliance.
Recent headlines involving Dino focus on unrelated matters, such as March 2026 Federal Police searches against a Maranhão blogger accused of illegally monitoring Dino’s security movements—a case authorized by Moraes and defended by Dino as protecting against stalking, not censorship. This has reignited debates on press freedom but overshadowed the SEI access allegations.
Why Was It Never Investigated?
The apparent lack of investigation underscores systemic issues in Brazil’s judicial process. Dino’s connections—his friendship with Gonet and influence within the STF—may have contributed to the inertia, though no evidence directly supports foul play. Political analysts suggest the complaint got lost in the shuffle of Maranhão’s factional infighting, where Dino’s group (including Solidariedade allies) clashes with Brandão’s administration, itself tangled in nepotism probes.
Critics argue this dormancy erodes public trust in the STF, especially amid broader concerns over judicial impartiality. If the accesses were benign, why not a swift clearance? If illicit, why no accountability? Without transparency, the scandal serves as a reminder of how power dynamics can stall justice, leaving serious allegations in a perpetual state of limbo.
As Brazil navigates its democratic challenges, cases like this demand scrutiny. Until an official probe materializes, the questions surrounding Dino’s cabinet will persist, a quiet testament to the complexities of politics and the law.
