Part of Flávio Bolsonaro complained about Lula's campaign mobilization using Meta platforms, which are subject to electoral court rules.

How could the electoral court ruling on algorithmic bias affect Facebook's operations?

Likely What happens if… A possibility worth considering, not a forecast.

Facebook must modify algorithms to ensure equal political campaign visibility A Brazilian electoral court ruled that Meta must immediately adopt measures to ensure equal treatment for presidential candidates Luiz Inácio Lula da Silva and Flávio Bolsonaro. This ruling mandates that Meta cannot reduce the distribution of political content or restrict searches in a way that creates an imbalance. As the owner of Facebook, Meta must implement these changes across its platforms, meaning Facebook's content delivery and AI tools must be modified to prevent the unjustified reduction of reach or artificial inflation of visibility for political content. Failure to comply could result in a fine of 500,000 reais per day.

The facts so far

As reported. Each one links to where it comes from.

  • A judge ruled Meta must secure equal treatment for the two presidential candidates ahead of the Oct. 25 runoff.whec.com, abcnews.com
  • Meta must pay a fine of 500,000 reais ($98,000) per day if it fails to comply with the ruling.whec.com
  • A study revealed Meta allowed 1,613 irregular political ads, generating roughly 2 million reais ($400,000) in revenue between July and September.abcnews.com
  • Lula’s campaign claimed Meta subjected Lula’s campaign materials to “unjustified reductions in reach.”whec.com

Why it matters

The ruling places a direct legal and operational burden on Meta and its platforms, including Facebook. The company must fundamentally alter how its algorithms distribute political content to ensure fairness, or face daily financial penalties. This is significant because the allegations centered on a stark disparity in visibility, with Lula's campaign claiming content faced delivery restrictions while opposing profiles received artificially inflated reach.

This case aligns with international precedents where courts have intervened to correct platform imbalances. For instance, in 2019, Germany’s Constitutional Court forced Facebook to restore a blocked political party page, establishing that tech giants must abide by constitutional principles of political equality.

What we don't know yet

  • How quickly will Meta implement the necessary algorithmic changes across Facebook and other platforms?
  • Will the court impose further restrictions on Meta's AI tools beyond ensuring identical criteria?
