Brazil Election: Lula and Bolsonaro Seek Rival's Disqualification Over Social Media Interference

Brazil Presidential Candidates Seek Mutual Disqualification Ahead of Runoff

Brazil’s tight-fought October 25 presidential runoff has escalated into a legal battle as both candidates petition the electoral court to disqualify their rivals over alleged social media interference. Incumbent left-wing President Luiz Inácio Lula da Silva and his right-wing challenger, Flávio Bolsonaro, traded accusations of digital manipulation just days before voters return to the polls.

The intensifying feud follows a first-round vote earlier this month where Flávio Bolsonaro—son of far-right former president Jair Bolsonaro—secured 47 percent of the vote compared to Lula’s 45 percent. With polls predicting a close race for the upcoming Sunday election, both camps are leaning heavily on the judiciary to sideline their opposition.

Flavio Bolsonaro Targets Lula Over WhatsApp Mass Messages

Lawyers for Flávio Bolsonaro filed a formal request with the Superior Electoral Court on Tuesday asking for the annulment of President Lula’s candidacy, citing what they termed unlawful propaganda. The Bolsonaro campaign alleged an “abuse of power” involving the mass dissemination of government postings via WhatsApp.

The petition claims that the Brazilian government pushed mass messages to millions of citizens through the messaging service to promote social programs, benefits, and government initiatives in the middle of the active presidential race. The filing asks the electoral court to declare both Lula and Social Communications Minister Sidonio Palmeira ineligible to hold public office for a period of eight years.

Lula Campaign Alleges Algorithmic Manipulation by Meta

In response, Lula’s campaign announced plans to petition for the disqualification of Bolsonaro over alleged election interference linked to WhatsApp parent company Meta. Lula’s petition alleges “algorithmic manipulation” by the tech giant designed to harm the incumbent’s chances of winning.

The friction with Meta intensified after Lula spent nearly 24 hours unable to boost his Instagram posts while his opponent faced no such restrictions, an episode submitted to the electoral court as evidence of platform bias. Meta attributed the restriction to a global outage affecting thousands of advertisers and a separate anti-fraud review that mistakenly classified an ad as an impersonation attempt, stating the issues were technical rather than political.

The Superior Electoral Court previously ordered Meta to ensure equal treatment for both candidates, warning of daily fines for noncompliance. The court subsequently increased the penalty to one million Reals (approximately $200,000 USD) per day after finding that Meta had failed to fully demonstrate compliance with the directive.

Court Orders and Platform Compliance

Meta representatives defended the company’s neutrality, stating that the platform applies identical rules to all political viewpoints and candidates in Brazil and globally. On Tuesday, Meta informed the electoral court that it had completed the implementation of all required measures to comply with the judicial decision.

The dispute shows the immense financial and political weight carried by digital platforms. Platforms like Google and TikTok barred political advertising for the cycle, leaving Meta’s services as the only large-scale channels for paid digital campaigning and generating £43 million for the company during the race.
