California state lawmakers introduced Senate Bill 1159 on Friday, giving public agencies the authority to block or filter comments that are generated by artificial‑intelligence tools. The measure, numbered 1159, targets the increasing volume of synthetic submissions that appear in government comment periods, which officials say can overwhelm the process and distort the representation of public opinion.
Supporters of the bill argue that the rise of AI‑produced content has created a new challenge for agencies tasked with reviewing citizen input on policy proposals, environmental reviews and other regulatory matters. By allowing agencies to identify and exclude non‑human generated remarks, the legislation aims to preserve the integrity of civic engagement and ensure that genuine community voices are not lost amid automated noise.
The bill does not prescribe specific technical standards for detection, but it authorizes agencies to adopt filtering mechanisms that meet the intent of the law. Lawmakers indicated that the legislation is a response to observed spikes in AI‑driven comment submissions across multiple state departments, where large numbers of identical or near‑identical statements have been recorded during public notice periods.
If enacted, agencies would be able to apply the new powers without needing separate judicial approval, streamlining the process of managing comment streams. The proposal is currently moving through the Senate and will be considered by the Assembly before any final vote. Advocates hope the measure will set a precedent for other jurisdictions facing similar challenges as AI tools become more accessible for mass content creation.
Stakeholders, including public interest groups and technology experts, have been invited to submit feedback during the bill's committee hearings. The outcome of those consultations will shape the final language of the legislation, which seeks to balance the protection of democratic participation with the practical realities of modern digital communication.
