The First Chamber of Brazil's Supreme Federal Court formed a majority on Thursday, May 7, 2026, to keep Deputy Thiago Rangel in preventive detention [2].
The ruling limits the ability of legislative bodies to interfere with judicial detention, signaling a stricter approach to lawmakers suspected of corruption. This decision prevents the Legislative Assembly of the State of Rio de Janeiro (ALERJ) from overturning the arrest.
Rangel, a member of the Avante party from Rio de Janeiro, is suspected of involvement in fraud and embezzlement related to contracts within the Rio de Janeiro State Education Secretariat [1]. These investigations are part of a larger probe known as Operation "Unha e Carne" [1].
The court reached its decision during a virtual extraordinary session. The vote count stood at 3-0 [4], with Ministers Flávio Dino and Cristiano Zanin following the understanding of Minister Alexandre de Moraes [2].
Justice Alexandre de Moraes said that the detention would remain "independentemente de manifestação" — regardless of any manifestation — from the legislative body [2]. The court's majority rejected the notion that the state legislature must approve the continued imprisonment of a deputy.
Other members of the court highlighted the necessity of preventing political privilege. Minister Cármen Lúcia said the situation was the "uso da imunidade como 'escudo' para impunidade," or the use of immunity as a shield for impunity [5].
While some reports indicated a pending vote from Minister Cármen Lúcia, others noted that the majority had already been established through the alignment of Dino, Zanin, and Moraes [2, 4].
“The vote count stood at 3-0”
This ruling reinforces the judiciary's authority over legislative immunity in Brazil. By barring the Rio de Janeiro state legislature from intervening in Rangel's detention, the Supreme Federal Court is establishing a precedent that parliamentary immunity does not protect officials from preventive detention when there is evidence of financial crimes, such as those alleged in Operation Unha e Carne.
