Brazil’s top electoral court suspended the presidential campaign of right-wing candidate Renan Santos after investigators found his party concealed 18 active digital profiles from electoral authorities.
Minister Dias Toffoli of the Superior Electoral Court ordered the precautionary measure against Santos, standard-bearer of the Missão party.
The precautionary measure also falls on the candidate for vice presidency, Aroldo Medina, after the mass dissemination of favorable content through undeclared digital profiles was detected before the judicial instance.

The ruling imposes an absolute prohibition on campaign propaganda, freezes disbursements from the Electoral Fund and bars the ticket from participating in debates on radio, television, podcasts and other media outlets.
Brazilian regulations require candidates to register every platform they intend to use for campaign outreach from the moment they file their candidacy.
Strategic Omission
The investigation established that the conservative group initially reported only one account on the social network X and an official website, while deliberately omitting 18 other active accounts across digital platforms.
For the magistrate, that lack of transparency breaches the mechanisms of citizen and legal oversight. Toffoli said the candidate knew in advance that he had to report the addresses and could only use them in the campaign after 48 hours of registration with the court.
“The candidate had prior knowledge that he should report the addresses and could only use them in the campaign after 48 hours of registration by the Superior Electoral Court. He frontally violated the obligation. The benefits already received are irreversible,” Toffoli ruled.
In this sense, the judge argued that hiding the profiles undermines the legitimacy of the entire campaign strategy and reflects a lack of adherence to current legal norms.

Text reads: “In justifying the suspension of Renan Santos’s campaign, Dias Toffoli attached a screenshot of Kim Kataguiri’s profile in which Instagram recommended the presidential candidate’s profile; according to the minister, this recommendation would have provided an alleged advantage to Renan, since the Superior Electoral Court prohibits platforms from recommending profiles of candidates to users who do not follow them.”
Campaign Frozen
The court’s decision responds to demands for greater institutional rigor in the face of parallel digital structures, a phenomenon that marked past elections and tested the ability of electoral justice to respond to disinformation.
The measure derails the ambitions of Santos, who ranked between third and fourth place in voting intention polls for the first round.
The suspension leaves his campaign without access to public funds, media presence and the visibility that debates provide at the height of the electoral season.

The case adds to a broader debate in Brazil over the transparency of political communication in the digital age. Electoral authorities have stepped up scrutiny of online operations after successive cycles revealed networks of coordinated accounts designed to amplify messages beyond the reach of official campaign structures.
