Brazil’s Supreme Court widens platform liability, including for bot-boosted posts

Source: STF judgment summary (Temas 987 and 533)Also reported by DPL News

Brazil’s Supreme Federal Court ruled 8 to 3 on 26 June 2025 that Article 19 of the Marco Civil da Internet is partly unconstitutional. Until Congress legislates, platforms can be held liable if they fail to remove unlawful content after a private notice, with a court order still needed for crimes against honour. Liability is presumed for paid ads and content spread by artificial distribution networks such as chatbots or bots unless the platform shows it acted diligently, and the ruling applies to future cases only.

Why it matters

Platforms in Brazil are presumed liable for paid ads and for content spread by bot networks unless they show they acted diligently, without waiting for a court order.
