Brazil’s STJ Justice Moura Ribeiro Under Federal Investigation

Politics

For the first time, a sitting justice of Brazil’s second-highest court is a formal target of a corruption inquiry. A Supreme Court justice has cleared the Federal Police to investigate Moura Ribeiro over an alleged scheme to sell court rulings.

The Superior Court of Justice, or STJ, is Brazil’s highest court for non-constitutional matters, one rung below the Supreme Federal Court. An investigation reaching one of its justices is rare and politically charged.

Now the Federal Police have been cleared to look into one of them.

What Zanin Authorized

Supreme Court Justice Cristiano Zanin authorized the Federal Police to investigate STJ Justice Moura Ribeiro as part of an inquiry into the alleged commercialization of court rulings at the STJ.

According to the reporting, Moura Ribeiro is the first STJ justice to become a formal target of the investigation, which has been underway at the Supreme Court since 2024.

The Allegations

Investigators say some decisions issued by the justice are suspected of being connected to a lobbyist, Andreson de Oliveira Goncalves, and his wife, Mirian Ribeiro.

The move follows charges filed in May by the Prosecutor-General’s Office against nine people in the same inquiry into the alleged sale of sentences at the court.

The Justice’s Response

Through a statement, Moura Ribeiro said he is unaware of the existence of an investigation opened in relation to decisions he has handed down.

No charges have been filed against him, and the authorization allows investigators to gather evidence; it is not a finding of wrongdoing.

Why It Matters

An inquiry reaching a member of the STJ strikes at the credibility of Brazil’s higher judiciary, at a time when public trust in institutions is closely watched.

How the case proceeds, and how the courts handle one of their own, will be a test of the system’s willingness to police itself.
