A judge of Brazil's top electoral court ruled on Thursday that Meta must adopt measures to immediately secure equal treatment of the two presidential candidates ahead of an Oct. 25 runoff.

The ruling comes shortly after President Luiz Incio Lula da Silva, who is running against Flvio Bolsonaro, filed a complaint that accused the tech company that owns Instagram, Facebook and WhatsApp of using biased algorithms and AI restrictions to favor opposition candidate Bolsonaro ahead of the election.

Justice Marco Aurlio Bellizze ruled Meta cannot reduce the distribution of political content, restrict searches or remove posts in a way that creates an imbalance between Lula and Bolsonaro.
