California bars using AI to fake public participation before government agencies

Governor Gavin Newsom signed SB 1159 on September 30, 2026. From January 1, 2027, no one may knowingly use AI to falsely represent that a natural person appeared before, submitted information to or engaged with a government agency. Under the Public Records Act, open-meeting laws, the Administrative Procedure Act, CEQA and the Coastal Act, AI systems, autonomous agents and robots are not persons or members of the public.
