TSE president suspends rejection of Deltan Dallagnol's Senate candidacy

Overview

Updated Oct 21

Deltan Dallagnol finished second in Paraná's Senate race on October 4. His votes were counted after the court's president suspended a rejection of his candidacy hours before polls opened. The TSE plenary has not yet ruled on whether the candidacy was valid.

The court was scheduled to hear the case on October 8, but President Kassio Nunes Marques removed it from the docket, citing a lack of time and unresolved procedural questions. No new date has been set. Deltan's Senate seat remains provisional; if the plenary upholds the rejection, his 2.9 million votes are void and the seat goes to the next candidate.

Why it matters

About 2.9 million votes are in legal limbo; if the TSE rejects Deltan, the Senate seat goes to the next candidate.

Scenarios

TSE plenary upholds Deltan's candidacy

Possible Resolves by End of 2026

Discussed by: Deltan's legal team, Novo party

The plenary rules that the TRE-PR correctly approved Deltan's registration. His votes are valid, and if he finishes in the top two, he takes a Senate seat. This would overturn Floriano's reasoning that Deltan resigned to avoid ineligibility.

TSE plenary rejects Deltan's candidacy

Possible Resolves by End of 2026

Discussed by: PT, PDT

The plenary upholds Floriano's reasoning that Deltan resigned from the prosecutor's office to avoid disciplinary proceedings. His votes are nullified, and the next candidate in the tally takes the seat.

Deltan loses the election, candidacy question becomes secondary

Deadline passed (Oct 5, 2026)

Discussed by: Election analysts

If Deltan finishes outside the top two in Paraná, the candidacy ruling matters less. The plenary may still rule, but the practical impact is limited to whether his votes are counted in the final tally.

TSE plenary rules on Deltan's candidacy before new Congress convenes

Likely Resolves by Feb 1, 2027

Discussed by: TSE, legal analysts

The TSE plenary must rule on Deltan's candidacy before the new Congress convenes. If it upholds the rejection, his votes are void and the seat goes to the next candidate.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

August 2018

Lula barred from 2018 election (2018)

Former president Luiz Inácio Lula da Silva was leading polls when the TSE barred his candidacy under the Ficha Limpa law, citing his corruption conviction. His running mate, Fernando Haddad, took his place and lost in the runoff to Jair Bolsonaro.

Then

Lula's party ran Haddad, who lost to Bolsonaro.

Now

The case established that Ficha Limpa applies even to frontrunners. Lula was later freed and won the 2022 election.

Why this matters now

Shows how the TSE applies Ficha Limpa to major candidates close to election day.

May 2023

Deltan's mandate cassated (2023)

The TSE voted 7-0 to cassate Deltan's federal deputy mandate, ruling he resigned from the prosecutor's office in 2021 to avoid disciplinary proceedings that could make him ineligible.

Then

Deltan lost his seat and was barred from running for eight years.

Now

The ruling set the precedent now being challenged in his Senate bid.

Why this matters now

This is the direct legal basis for the challenge to Deltan's Senate candidacy.

June 2010

Ficha Limpa law takes effect (2010)

Brazil's Congress passed the Ficha Limpa law, barring politicians convicted of crimes by a collegiate court from running for office for eight years. The law was first applied in the 2010 elections.

Then

Hundreds of candidates were barred in the 2010 elections.

Now

The law became a central tool in Brazilian electoral politics, used to bar Lula in 2018 and now Deltan.

Why this matters now

The law at the center of Deltan's case was first applied in 2010.
