Brazil’s presidential candidates push to have one another disqualified ahead of run-off

Both campaigns are asking Brazil’s electoral courts to remove their rival from the presidential race. Lula’s campaign plans to seek Flavio Bolsonaro’s disqualification. Bolsonaro’s team has filed a case seeking action against Lula. The allegations matter because they concern whether digital systems and official communications distorted the campaign.

Lula’s side accuses Meta, which owns Facebook, WhatsApp, and Instagram, of algorithmic manipulation that allegedly limited Lula-related content and helped Bolsonaro. Bolsonaro’s team accuses Lula of “abuse of power” through the mass sharing of government postings on WhatsApp during the campaign. Meta denies favoring either candidate and says some Lula advertisements were mistakenly deactivated by technical errors.

The Superior Electoral Court ordered Meta to prove equal treatment of both campaigns within 24 hours. It threatened a daily fine of about $200,000. Lula’s petition was expected Tuesday but was later scheduled for Wednesday. The court’s response could shape the final days before Sunday’s vote.

Brazil’s Superior Electoral Court, known as the TSE, is the highest judicial authority for national election matters. It oversees legal disputes involving candidates, campaigns, voting, and election-related conduct. Its role matters here because both presidential campaigns claim that digital activity or official communication may have distorted the contest.

The court can examine petitions seeking a candidate’s disqualification or the annulment of a candidacy. It can also order campaign platforms to follow equal-treatment requirements. In this dispute, the TSE gave Meta 24 hours to prove that it was treating both campaigns equally. The order included a possible daily fine of around $200,000.

The article does not describe the court’s full powers or the exact legal test for removing a candidate. It does show that the TSE can demand evidence from a major technology company and threaten financial penalties. Its rulings could therefore affect campaign communications before the runoff.

The first-round result was extremely close in percentage terms. Flavio Bolsonaro received 47 percent of the vote, while incumbent President Luiz Inacio Lula da Silva received 45 percent. That is a two-percentage-point difference, leaving neither candidate with a majority and sending the election to a runoff.

The figures show why both campaigns were fighting intensely over the final contest. The article describes polls ahead of Sunday’s runoff as a technical tie. It also says the first-round result energized Lula’s supporters, who organized large rallies and sought to improve the campaign’s social-media performance.

The article does not provide the total number of votes cast or the exact vote counts for either candidate. Therefore, the number of voters separating them cannot be determined from the supplied information. Only the percentage gap, two percentage points, can be stated confidently.

“Algorithmic manipulation” refers to the alleged use of automated recommendation, moderation, or distribution systems to change which political material people see. Lula’s campaign says Meta limited Lula-related election content while leaving Bolsonaro content untouched. The allegation matters because online visibility can influence which messages reach voters during a close race.

The key mechanism is different for each accusation. Lula points to Meta’s systems across Facebook, Instagram, and WhatsApp, including an artificial-intelligence tool that allegedly treated related content inconsistently. Bolsonaro’s team points to Lula’s mass sharing of government postings on WhatsApp and calls that “abuse of power.” In that context, the phrase means allegedly using official resources or influence for campaign benefit.

These are allegations, not established findings in the article. Meta denies favoring either side and says some Lula advertisements were deactivated accidentally because of technical errors. The Superior Electoral Court is examining compliance and could impose penalties for unequal treatment.

If a court disqualified one candidate before voting day, that candidate could lose the right to compete in the runoff. The immediate consequence would be a major change to the ballot and to the choice presented to voters. Because the article does not explain Brazil’s detailed replacement rules, the exact outcome cannot be stated from the supplied text.

The dispute is especially consequential because the race is close. Flavio Bolsonaro led Lula 47 percent to 45 percent in the first round, while polls described the runoff as a technical tie. A disqualification would therefore affect a contest in which both campaigns are actively challenging the other’s conduct and digital strategy.

The Superior Electoral Court would be central to any decision because it is handling the filings and has already ordered Meta to prove equal treatment. The article does not say whether voting would be delayed, whether another candidate would replace the disqualified contender, or whether the runoff would continue with one candidate.

A second round gives voters a direct choice between the leading candidates when nobody wins a majority in the first round. The purpose is to ensure that the eventual president receives more than half of the valid votes in the final contest. This is a general explanation of runoff elections; the supplied article does not explain Brazil’s electoral rules in detail.

In this election, Flavio Bolsonaro received 47 percent in the first round, and Lula received 45 percent. Neither reached a majority, so they advanced to Sunday’s runoff. The article says polls showed a technical tie, making the second contest highly competitive.

The runoff also concentrates the campaign’s final arguments. Lula’s camp is challenging Bolsonaro’s candidacy over alleged Meta interference. Bolsonaro’s team is accusing Lula of abuse of power involving government postings on WhatsApp. The court disputes therefore unfold just as voters prepare to choose between the two first-round leaders.

A social-media company influences elections through several connected systems. Content-ranking tools decide which posts appear prominently. Advertising systems determine whether campaign messages are approved, targeted, or removed. Messaging systems affect how easily users receive and forward political material. Together, these choices shape the information voters encounter.

The article gives a concrete example. Lula’s campaign says Meta’s artificial-intelligence tool limited Lula-related election content while leaving Bolsonaro content untouched. It also says some Lula advertisements were deactivated. Bolsonaro’s team, meanwhile, accuses Lula of mass sharing government postings on WhatsApp. These allegations concern different ways political information can gain or lose reach.

Meta denies taking actions to favor either candidate and says technical errors caused some ad deactivations. The Superior Electoral Court ordered Meta to demonstrate equal treatment and threatened a daily fine of around $200,000. In a close race, platform decisions can become a major legal and political issue.
