TSE candidate vetting can end in rejection over alleged organized crime ties even without a conviction, as Rio deputy-elect Márcio Canella’s case shows. This explainer sets out the law and deadlines, while our Brazil election 2026 coverage follows the vote.
The case leaves the presidential race alone, so the Brazil election polls, the Brazil election odds and the Brazil runoff date stay unchanged. Our news report on the electoral prosecutor’s request against Canella covers the filing itself.
TSE Candidate Vetting in Plain Terms
TSE candidate vetting is run by Brazil’s electoral justice, led by the Superior Electoral Court, which registers candidates and settles who may run. Before anyone appears on a ballot, a court must approve the registration, and approval can be challenged.
A challenge to a registration is called an impugnação in Portuguese. It is the main tool of the electoral prosecution when it believes a candidate is barred from office, including over alleged ties to criminal groups.
Who Decides: The TSE, Regional Courts and the Prosecutor
Complementary Law 64 of 1990, published on the Planalto presidency’s legal database, says the TSE judges challenges to presidential candidates. Regional electoral courts, the TREs, judge senators, governors and federal and state deputies, so a Rio state deputy starts at the TRE-RJ.
In TSE candidate vetting, the Ministério Público Eleitoral, the electoral prosecution, is the part of Brazil’s federal prosecution service that acts. The same law lets any candidate, party or coalition file a challenge, and that does not stop the prosecutor from acting.
Two Legal Roads: Ficha Limpa and the Paramilitary Ban
The first road is the Ficha Limpa, or Clean Record, law, Complementary Law 135 of 2010, signed on 4 June 2010. It makes a person ineligible after a conviction by a panel of judges, even while appeals continue, until eight years after the sentence is served.
The crimes listed include money laundering, drug trafficking, terrorism and crimes committed by a criminal organization, a gang or a band. Ficha Limpa therefore needs a conviction, and an inquiry or an arrest alone does not trigger it.
The second road is Article 17, paragraph 4, of the Constitution, which says political parties may not use a paramilitary organization. In May 2025 the TSE unanimously upheld a ban on a Belford Roxo council candidate, and prosecutors say the Constitution was the ground.
That candidate had been convicted of forming a private militia and sentenced to eight years, the same release says. The electoral prosecution argues that TSE rulings let it bar politicians tied to such groups without a final conviction, if the evidence is solid.
Steps and Deadlines of TSE Candidate Vetting
TSE candidate vetting begins when parties file registrations, by 7 p.m. on 15 August of an election year, under the electoral law of 1997. For 2026 the TSE calendar sets 14 September as the date by which lower courts must decide every registration, challenged ones and their appeals included.
Under Complementary Law 64, a challenge must come within 5 days of the publication of the registration request. The candidate then has 7 days to answer, and the law gives 4 days to hear witnesses when needed and 5 days for final arguments.
The judge or rapporteur then decides, and an appeal to the TRE or the TSE normally has to be filed within 3 days of publication. These deadlines are continuous and do not pause for weekends or holidays after the registration deadline, the law says.
A candidate whose registration is still disputed on election day may campaign and appear on the ballot, under Article 16-A of the electoral law. Votes for that candidate count only if a higher court finally approves the registration.
The Canella Case as a Live Example
Márcio Canella, of the União Brasil party, is a former mayor of Belford Roxo, a city in Rio’s Baixada Fluminense area. He won 197,178 votes for the Rio state assembly, the second-highest total among state deputies in Rio, Metrópoles and O Antagonista report.
On Friday 23 October 2026, deputy electoral prosecutor-general Alexandre Espinosa asked the TSE to bar Canella’s registration, Metrópoles, Gazeta do Povo and O Antagonista report. It also asks the TSE to overturn the TRE-RJ decision that cleared him.
The filing says Canella acted as a political organizer of a criminal scheme and cites alleged militia and Comando Vermelho gang ties, Metrópoles reports. Gazeta do Povo adds that it alleges he appointed militia leaders to city posts and received money from the scheme.
Metrópoles says the prosecutor argues that the Rio court ruled before seeing evidence from a Supreme Court inquiry, whose secrecy was lifted this month. Tribuna do Sertão reported that the TRE-RJ approved his registration by 6 votes to 1 on Tuesday 29 September.
That inquiry is Operation Unha e Carne, in which Canella was arrested on Thursday 15 October, Gazeta do Povo reports. Police say a fuel-station network moved R$7.6 billion (about US$1.5 billion) in six years, and no conviction against Canella has been reported.
Our earlier reports cover the arrest in the fuel-laundering probe and the three elected candidates flagged for crime links. The outlets carry no reply to the new filing, though his lawyer earlier called the militia claim an extravagant story, Tribuna do Sertão reported.
What Happens After the Vote
Winning does not end TSE candidate vetting, since a mandate can be challenged within 15 days of the ceremony where winners receive their certificate. That ceremony is called the diplomação, and the challenge needs proof of abuse of economic power, corruption or fraud.
If a court finally rejects a registration, the electoral law says votes cast for that candidate do not count. The TSE must now decide whether to keep or reverse the Rio ruling, and none had been reported by Saturday 24 October.
What It Means for US Readers
TSE candidate vetting shows how Brazil’s courts handle alleged criminal infiltration of politics, which matters to anyone following the country’s institutions. This case concerns one Rio state seat and does not affect the presidential runoff, trade or travel.
Observers should watch whether the TSE accepts the prosecution’s reading that credible evidence can bar a candidate without a conviction. A ruling for the prosecution would set a precedent for TSE candidate vetting of other elected figures questioned over crime links.
What Is Not Known
It is not known when the TSE will finish its candidate vetting of Canella or whether it will accept the opinion. Nor is it known how his 197,178 votes will be treated if the TSE reverses the Rio ruling.
No court has ruled on the new allegations, and Canella has not been convicted of any crime in the cases cited. His defense has not been reported responding to the filing, and the facts are for the courts to decide.
