Brazil electoral court (TSE) rules on AI in campaigns
Brazil requires labels on AI content in election campaigns and bans deepfakes. For 2026, new AI content using candidates’ image or voice was banned from 72 hours before voting until 24 hours after.
Brazil’s Superior Electoral Court first set AI rules for campaigns in 2024: AI-generated or altered content must be labelled, deepfakes are banned, and chatbots may not pose as candidates. Resolution 23.755 of 2 March 2026 tightened them for the October 2026 elections.
New AI content using the image, voice or statements of candidates or public figures was banned from 72 hours before the end of voting until 24 hours after, even if labelled. Platforms selling boosts for political content must let advertisers declare AI use, and AI systems may not recommend candidates or how to vote, even when asked. Fines range from R$5,000 to R$30,000, and serious abuse can cost a candidate their registration or mandate.
