Brazil Election 2026: Court Suspends Deltan Dallagnol’s Senate Campaign
Key Facts
Brazil’s electoral court has frozen the Senate campaign of Deltan Dallagnol, the prosecutor who became the face of the Car Wash corruption inquiry. The injunction, signed on Saturday 19 September, takes him off the air in Paraná two weeks before the vote.
It is a provisional order, not a final ruling on whether he may run. Yet in a race he was narrowly leading in one poll, fifteen days without a campaign may matter as much as the verdict.

What the Order Blocks
Justice Floriano de Azevedo Marques of the Superior Electoral Court (TSE) granted the injunction, G1 reported. It suspends campaign acts and the transfer of money from the Party Fund and the public campaign fund.
He may not use funds already received, air free television and radio slots, or join debates, Poder360 and Folha reported. The order stands until the court judges the appeal against his candidacy registration.
The justice asked the court’s presidency to put the case before the full bench in the next few days, G1 reported. No date had been confirmed by Sunday.
The request came from the Paraná Para Todos coalition and the Brasil da Esperança federation, Banda B reported. Gazeta do Povo described it as a request from the Workers’ Party, which leads that federation.
A Candidacy Already Split the Regional Court
Paraná’s regional electoral court had approved Dallagnol’s registration on 8 September by four votes to three. That narrow result is what the coalition appealed to the TSE in Brasília.
O Tempo reported that the suspension is tied to the Clean Record Law, which bars candidates on grounds such as removal from office. The reports did not set out the justice’s full reasoning.
A regional judge had argued that the 2023 decision costing him his seat did not affect his eligibility, Folha reported. The TSE now has to settle that question for the whole race.
Who Deltan Dallagnol Is
Dallagnol coordinated the federal prosecutors of the Car Wash inquiry, known in Brazil as Lava Jato. From 2014 it exposed bribery around the state oil company Petrobras and sent leading politicians and executives to prison.
He left the prosecution service and was elected a federal deputy in 2022 with a large vote. In May 2023 the TSE annulled that election, ruling he had resigned while disciplinary proceedings against him were pending.
He is now running for one of Paraná’s two Senate seats for Novo, a small free-market party. A CNN Brasil poll on 18 September put him at 31.6% in one scenario, against 30.4% for his rival Curi.
No reaction from Dallagnol to the order appeared in the reports reviewed. He can ask the full court to reverse it, and his registration appeal is still pending.
A Justice Takes Aim at the Electoral Court’s Leaders
The ruling landed amid open conflict among the judges who oversee the election. On Sunday 20 September, Supreme Court justice Gilmar Mendes posted a pointed message on X.
Whoever tries to drag the court into partisan proselytism should consider whether they can stay on it, he wrote. He urged parties and electoral prosecutors to raise recusal claims where they apply.
Gazeta do Povo read the post as aimed at Kassio Nunes Marques and André Mendonça, the TSE’s president and vice-president. Both were appointed to the Supreme Court by former president Jair Bolsonaro.
The clash follows a heated Supreme Court session on 15 September over messages from the phone of jailed banker Daniel Vorcaro. There Gilmar Mendes said Mendonça had shown an evident political and electoral bias, G1 reported.
Why It Matters Beyond Paraná
Car Wash still divides Brazil more than a decade after it began. For one side Dallagnol is a symbol of the fight against graft, and for the other a prosecutor who used the law for politics.
Whatever the court decides, the ruling will be read through that divide. The first round of the general election is on Sunday 4 October, with runoffs on 25 October.
Two-thirds of the Senate is up for election this year, and only the Senate can try impeachment cases against Supreme Court justices. That gives races such as Paraná’s national weight in a year of open conflict between judges and politicians.
Two of Paraná’s three Senate seats are on the ballot. Voters there will decide whether to send a Car Wash symbol to Brasília, unless the court decides the question for them first.
