Brazil's Lula wins electoral court challenge against Meta for alleged pro-Bolsonaro algorithm bias
SAO PAULO — 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.

TL;DR
- A judge ruled Meta must provide equal treatment for Brazilian presidential candidates Lula and Bolsonaro on its platforms.
- The ruling came after Lula's campaign accused Meta of using biased algorithms and AI to favor Bolsonaro.
- Meta is ordered to not reduce political content distribution, restrict searches, or remove posts in a way that creates imbalance.
- The company's artificial intelligence tools must apply identical criteria to both candidacies.
- Meta faces a fine of 500,000 reais ($98,000) per day for non-compliance.
- Lula's campaign claims Meta has reduced the reach of his campaign materials while artificially inflating Bolsonaro's visibility.
- Disparities were noted in Meta's AI tools, with users reportedly unable to generate campaign images for Lula but able to for Bolsonaro.
- Meta previously rejected accusations of bias, citing technical glitches affecting accounts globally and asserting compliance with electoral regulations.
