Brazil Court Delays Fate of 2.9 Million Dallagnol Votes

BRAZIL · POLITICS

Brazil’s top electoral court has put off deciding whether the former Car Wash prosecutor can take his Senate seat.

Brazil’s Superior Electoral Court (TSE) postponed a ruling on Thursday, 8 October, on Deltan Dallagnol’s Senate win in Paraná. No new date was set, so about 2.9 million votes remain legally in doubt.

Dallagnol led Operation Car Wash (Lava Jato), the bribery probe linked to Petrobras’s 2018 US settlement. The fight over the Dallagnol Senate seat tests how Brazil’s courts treat conservative winners after the 4 October vote.

What the Electoral Court Put Off

The TSE, which runs and polices Brazilian elections, listed the case on its Thursday agenda, published on Wednesday evening. It is an appeal against the Paraná regional electoral court, which approved Dallagnol’s Senate registration for the Novo party.

The appeal asks the TSE to reject the registration and annul the votes for his ticket, according to the court’s agenda. The rapporteur is Justice Floriano de Azevedo Marques.

The session opened at 10:00 Brasília time with 16 cases listed. By 13:00 the news site Poder360 reported that the Dallagnol case had been postponed, without giving a reason.

The same session annulled the votes of Anthony Garotinho in Rio de Janeiro’s governor race. That ruling handed Rio to Bolsonaro’s Liberal Party without a runoff.

Why His Eligibility Is Disputed

The case turns on Brazil’s Clean Record Law, which bars some officials from office for eight years. It covers prosecutors who resign while disciplinary proceedings are pending against them.

Dallagnol left the Federal Public Prosecutor’s Office in 2021.

His opponents say he quit early to escape that ban. The TSE accepted that argument in May 2023 and stripped him of his House seat.

In September, the Paraná court cleared him by four votes to three, finding he had not resigned to dodge the rule. The appeal came from the Paraná para Todos coalition and the Brazil of Hope federation, led by Lula’s Workers’ Party.

On Saturday, 3 October, Justice Floriano rejected the registration on his own. On the morning of Sunday, 4 October, TSE president Kassio Nunes Marques suspended that order, and Dallagnol’s votes were counted.

How the Paraná Senate Race Ended

Paraná, a farm and industrial state in southern Brazil, elected two senators on 4 October. Filipe Barros of the Liberal Party took 27.25% and Dallagnol 25.14%, Poder360 reported.

Novo is a small free-market, conservative party. The Liberal Party belongs to former president Jair Bolsonaro, whose son Flávio faces Lula in the 25 October runoff.

What It Means for You

For US investors, the Senate matters beyond one seat. It approves central bank directors and Supreme Court justices, and it alone can try justices for impeachment.

Petrobras, whose shares trade in New York, agreed in 2018 to pay US$853.2 million to settle a US Justice Department bribery case. The department’s release credited Brazilian law enforcement for its help in that investigation.

A prolonged fight over the Dallagnol Senate seat would add to legal uncertainty around Brazil’s election results. Investors in Brazilian assets have watched the courts closely since the Rio ruling.

What Is Not Known

The TSE has not published why the case was postponed or when it will return to the agenda. It is also unclear how the seat would be filled if his votes were annulled.

Dallagnol had not commented publicly on the postponement in the sources reviewed. The TSE had not posted an official note on the session result by Friday morning.

What Comes Next

The case returns once the court reschedules it. Until then, Dallagnol’s registration stands as approved under appeal.

The postponement does not mean the TSE has ruled for or against him. Senators elected on 4 October take office on 1 February 2027.
