What the STJ does and why it matters
The Superior Court of Justice, known by its Portuguese acronym STJ, sits just below Brazil’s Supreme Federal Court. It is the court of last resort for interpreting federal legislation that does not raise constitutional questions, handling everything from tax disputes and public procurement cases to criminal appeals involving high-ranking officials.
For foreign investors and diplomats, the STJ’s consistency is a pillar of legal predictability. When its rulings appear open to purchase, the entire framework of contract enforcement and regulatory stability comes under a cloud.
How the alleged scheme operated
According to the Federal Police, the suspected mechanism relied on draft rulings—internal working documents that signal how a justice intends to vote. Investigators believe lobbyists and former court staff acted as intermediaries, allegedly brokering access to these drafts and, in some cases, to the final decisions themselves.
The probe points to a network involving Andreson de Oliveira Gonçalves, his wife Mirian, and other operators who allegedly traded on their influence inside the court. In May 2026, the Prosecutor General’s Office charged nine individuals with crimes including criminal organization, active and passive corruption, money laundering, exploitation of prestige, and breach of professional secrecy.
A sitting justice enters the crosshairs
The investigation took a dramatic turn when Supreme Court Justice Cristiano Zanin authorized the Federal Police to formally target STJ Justice Paulo Dias de Moura Ribeiro. He is the first member of the court to be directly investigated in this case, moving the scandal from the court’s periphery to its bench.
The STJ has responded with internal disciplinary measures, including the precautionary removal of at least one staff member cited in the investigation. The court has stated publicly that it has found no evidence so far of involvement by its ministers beyond the one now under investigation.
The Luiz Estêvão connection
Federal Police are also tracing whether the alleged scheme benefited businessman Luiz Estêvão, a former senator who was impeached and later convicted for his role in a massive construction fraud scandal involving the São Paulo Regional Labor Court. Estêvão’s name resurfacing in a judicial corruption probe adds a layer of historical resonance for Brazilians familiar with his past.
For international observers, the link underscores a recurring risk: that actors with a history of manipulating the justice system may still find avenues to influence outcomes in the country’s highest courts.
What this means for legal certainty
A functioning judiciary is the bedrock of Brazil’s investment climate and its democratic institutions. When draft rulings become commodities, the impartiality that underpins contract law, bankruptcy proceedings, and anti-corruption enforcement is called into question.
The widening probe signals that accountability mechanisms, including the Supreme Court’s oversight and the National Justice Council’s disciplinary powers, are being activated. Yet each new revelation tests the confidence of expatriates, foreign companies, and diplomats who depend on a predictable rule-of-law environment.
