Brazilian Electoral Court Gives Meta 24 Hours to Prove Equal Treatment of Lula and Bolsonaro

Meta maintains that temporary technical glitches, not political bias, caused the recent disruptions to campaign content on its platforms. But Brazil's Superior Electoral Court (TSE) rejected that explanation on Monday, ordering the company to prove within 24 hours that its algorithms are treating the country's two presidential candidates equally.[1][3]

Justice Marco Aurélio Bellizze doubled the daily fine for non-compliance to 1 million reais ($200,000). The escalation came after Meta failed to meet previous court orders to detail how it distributes political posts and advertisements across Facebook, Instagram, and WhatsApp.[1][3]

Bellizze stated that the deadlines previously set by the tribunal had already expired. He emphasized that it is not up to Meta to define its own reporting timeline, rejecting the company's attempts to submit documentation on a delayed schedule.[3]

The legal intervention arrives less than a week before the October 25 runoff election. Incumbent President Luiz Inácio Lula da Silva faces challenger Senator Flávio Bolsonaro following a tight first-round vote on October 4, where Bolsonaro secured 47 percent to Lula's 45 percent.[1]

The dispute began when Lula's campaign filed a formal complaint alleging that Meta subjected his organic posts and campaign materials to unjustified reductions in reach. The filing also claimed that Meta's artificial intelligence tools prevented the creation of images favorable to the incumbent while allowing similar content for his rival.[1][3]

Internal messages contradict neutrality claims

The campaign's allegations gained traction after the Brazilian newspaper Folha de S.Paulo published internal communications between Meta employees. The messages reportedly showed staff acknowledging that Lula's accounts were facing restrictions, while the platform's algorithms actively recommended Flávio Bolsonaro's profile and WhatsApp channel.[1][2]

Michel Bertoni, a lawyer representing Lula's campaign, argued that the platform's metrics demand immediate correction. He asserted that when a major digital platform restricts the circulation of political content unevenly, it directly compromises electoral regularity and interferes with national sovereignty.[2]

Civil society groups have backed the campaign's concerns. A coalition of more than 100 organizations, including Global Witness and Oxfam Brazil, signed a letter demanding that Brazilian authorities enforce rules to rein in the technology giant's influence over the electoral debate.[1]

Daniela da Silva, executive director of the digital rights nonprofit CTRL+Z, noted that political campaigns in Brazil have drastically increased their spending on Meta's platforms. According to TSE data, Facebook received more than 200 million reais ($40 million) in advertising revenue during the 2024 municipal elections.[1]

"These are very powerful, wealthy companies, and they do have the capacity to do much more than they are doing," da Silva told Al Jazeera. She emphasized that Brazilian citizens have the right to know why their posts disappear or lose reach during a critical election period.[1]

Both campaigns allege platform interference

While the initial complaint came from the incumbent's team, Flávio Bolsonaro's campaign filed its own grievance with the TSE on Friday. His lawyers argued that systemic failures at Meta have actually harmed his candidacy more than Lula's.[3]

The Bolsonaro campaign alleges that Meta permitted the boosting of negative advertisements against the senator. They also claim the platform allowed the circulation of AI-generated ads produced by Lula's team without the mandatory warning labels for synthetic content.[3]

The court's mandate now explicitly requires Meta to apply identical rules and AI generation criteria to both campaigns. The company must also inform the court of the exact parameters it uses to accept or reject requests for political and electoral content.[3]

The TSE order demands that Meta provide individualized reports on political advertisements and explain how its recommendation systems function. The court also required the company to present investigations into potential networks of inauthentic profiles operating on its platforms.[3]

Bellizze specifically ordered that all documentation be submitted in Portuguese. He noted that a previous report provided by Meta contained foreign-language terms that failed to distinguish between actions taken by judicial order and those initiated by the company itself.[3]

The limits of algorithmic transparency

Meta's Brazil office issued a statement denying any intentional interference or favoritism in the 2026 general elections. The company acknowledged that temporary technical failures had affected Lula's campaign but insisted these were global incidents rather than targeted suppression.[1][3]

The court's ruling strictly prohibits Meta from reducing the distribution of publications, limiting recommendations, or restricting search results unequally between the candidates. However, restrictions remain permissible if they are based on platform policies applied uniformly to all users.[3]

Bellizze clarified that his directives do not extend to the content of opinions expressed by individual users on the social networks. The focus remains entirely on the underlying architecture that determines which posts gain visibility and which are suppressed.[3]

The standoff highlights the growing friction between national electoral authorities and multinational technology platforms. As campaigns increasingly rely on algorithmic distribution rather than traditional broadcasting, courts are struggling to audit the automated systems that govern digital speech.[1][2]

"The continued noncompliance, just a few days before the run-off election, demonstrates that the fine imposed was insufficient," a TSE judge stated in the order. With the runoff vote scheduled for Sunday, the 24-hour deadline forces Meta into a tight corner.[1]

If the company fails to produce the required transparency reports, the accumulating fines will test the TSE's ability to enforce compliance from a foreign-headquartered corporation. For now, the electoral court has made it clear that it will not accept opaque technical explanations when the integrity of the presidential race is at stake.[1][3]
