Brazil’s top electoral court has rejected the Dallagnol Senate candidacy in the southern state of Paraná, on the eve of Sunday’s election. Justice Floriano de Azevedo Marques ruled alone on Saturday evening, 3 October, and ordered every vote for the candidate treated as null.
Deltan Dallagnol, the former prosecutor who led the Car Wash corruption inquiry, still appears on the electronic voting machines. The ruling turns the suspension of his campaign, first reported on 20 September, into a rejection of his registration as a candidate.
From Suspension to Rejection in Four Weeks
The Dallagnol Senate case has moved in steps since early September. On 8 September, Paraná’s regional electoral court approved his registration by four votes to three.
Opponents appealed to the TSE, the Superior Electoral Court in Brasília that runs and polices Brazilian elections. On 19 September, Justice Floriano de Azevedo Marques froze the campaign with an injunction.
On 21 September the full court upheld that freeze by five votes to two. From then on, Dallagnol could not ask for votes, join debates or air radio and television spots.
Saturday’s decision goes further. It rejects the registration itself, not only the campaign, and tells Paraná’s electoral court to change his status to rejected at once.
Why the Court Says He Cannot Run
The legal basis is the Ficha Limpa, or Clean Record, law of 2010. It bars prosecutors and judges who resign while facing disciplinary proceedings from running for office for eight years.
In 2023 the TSE ruled that Dallagnol’s resignation from the federal prosecution service in November 2021 was designed to avoid that ban. On that basis it stripped him of the seat in Congress he had won in 2022.
Floriano found the 2026 case identical, CartaCapital reported. In his words, the resignation “aimed to avoid triggering the ineligibility rule”, and closing the disciplinary files later did not erase that.
CartaCapital reported that the eight-year ban runs from 3 November 2021 to 3 November 2029. The wider debate over the law is explained in this earlier piece on Ficha Limpa.
What Happens to the Votes
The voting machines were already prepared and sealed, so his name and number 300 remain on them, CNN Brasil reported. Under the ruling, every vote cast for him in Paraná counts as null.
Paraná elects two senators this year. Poder360 explained beforehand that, if he is barred on polling day, the two seats go to the leaders in valid votes.
That makes the Dallagnol Senate vote unusually consequential: a Neokemp poll published on 3 October put him first on 24.9%. Filipe Barros of Jair Bolsonaro’s Liberal Party followed on 23.5%.
Gleisi Hoffmann of President Lula’s Workers’ Party stood on 15.3% in that survey. A separate Real Time Big Data poll, reported by CartaCapital, also had Dallagnol leading, on 21%.
Who Brought the Case and How He Responded
The challenge to the Dallagnol Senate registration came from the Brasil da Esperança federation, led by Lula’s Workers’ Party. The Paraná para Todos coalition also filed, Gazeta do Povo reported.
Dallagnol answered in a video on social media: “This story is not over”, Maringá Post reported. Portal A Nativa quoted him calling the ruling “the biggest electoral violence in Brazil’s history”.
He asked why one justice decided alone, and said the same justice had ruled differently two days earlier. He also alleged pressure from the Workers’ Party and from Supreme Court Justice Alexandre de Moraes.
His lawyer, Leandro Rosa, told the newspaper Estadão: “We will certainly appeal.” Sergio Moro, the former Car Wash judge running for Paraná governor, said: “We will not accept an arbitrary and illegal decision.”
What the Ruling Does Not Mean
The decision is not a criminal conviction, and Dallagnol has not been found guilty of any crime. The question is whether he may hold elected office before November 2029.
It is also not final, because one justice signed it alone. The full court must still review the Dallagnol Senate ruling, as it did with September’s campaign freeze.
Nor does it touch the presidential race, where Lula faces Senator Flávio Bolsonaro, the former president’s eldest son. The contest is explained in this guide to Sunday’s vote.
What Comes Next
Polls close at 17:00 Brasília time, 20:00 UTC. Results begin to arrive within hours, as this guide to tonight’s count sets out.
Under the ruling, his votes in Paraná go into the null column. If the full court later overturns it, his lawyers say those votes would count and he could still win a seat.
The timing of that review has not been announced. Until it happens, the Dallagnol Senate result in Paraná carries an asterisk.

Who is Deltan Dallagnol?
He is a former federal prosecutor who led Car Wash, the corruption inquiry that jailed politicians and business leaders from 2014. He won a seat in Congress in 2022 but lost it in 2023. This year he ran for the Senate in Paraná for the Novo party.
Can voters in Paraná still choose him?
Yes. His name and number 300 are on the voting machines, which were sealed before the ruling. Under the decision, however, those votes count as null in the Dallagnol Senate count.
Could the decision be reversed?
Yes. One justice signed it, and the full seven-member electoral court must still review it. His lawyers say they will appeal, and a reversal would make his votes valid again.
Does this affect the presidential election?
No. The ruling concerns one candidate for one of Paraná’s two Senate seats. The race between Lula and Flávio Bolsonaro is not affected.
