Summary
Official abstract published by the California legislature· summary
The California Constitution provides that people have the right of access to information concerning the conduct of the people's business. Various provisions of existing law, including the California Public Records Act, the Legislative Open Records Act, the Bagley-Keene Open Meeting Act, and the Ralph M. Brown Act, provide, with some exceptions, for public access to government records and meetings of government bodies. Among those acts, the California Public Records Act defines "person" to include any natural person, corporation, partnership, limited liability company, firm, or association.
Existing law, the Administrative Procedure Act, governs, among other things, the procedures for the adoption, amendment, or repeal of regulations by state agencies and for the review of those regulatory actions by the Office of Administrative Law.
Existing law, the California Environmental Quality Act (CEQA) , requires a lead agency, as defined, to prepare, or cause to be prepared, and certify the completion of an environmental impact report on a project that it proposes to carry out or approve that may have a significant effect on the environment or to adopt a negative declaration if it finds that the project will not have that effect. CEQA defines "person" to include any person, firm, association, organization, partnership, business, trust, corporation, limited liability company, company, district, county, city and county, city, town, and, among other things, the state.
Existing law, the California Coastal Act of 1976, establishes the California Coastal Commission and prescribes procedures for the preparation, approval, and certification of local coastal programs that regulate development in the coastal zone, as defined, in jurisdictions that have a certified local coastal program.
This bill would specify that, for purposes of the California Public Records Act, the Bagley-Keene Open Meeting Act, the Ralph M. Brown Act, the Legislative Open Records Act, the Administrative Procedure Act, the California Coastal Act of 1976, and CEQA, "person," "interested person," "participant," "member of the public," as applicable, and any other similar terms under each act referring to those who may engage with governmental agencies, do not include artificial intelligence, as defined, systems, autonomous agents, or robots, whether physical or digital. The bill would authorize governmental agencies to use a disclosure verification tool to determine if artificial intelligence is present. The bill would make findings and declarations related to these provisions.
The bill would prohibit a person from knowingly using artificial intelligence to falsely represent that a natural person appeared before, submitted information to, or otherwise engaged with a governmental agency.
The California Constitution requires local agencies, for the purpose of ensuring public access to the meetings of public bodies and the writings of public officials and agencies, to comply with a statutory enactment that amends or enacts laws relating to public records or open meetings and contains findings demonstrating that the enactment furthers the constitutional requirements relating to this purpose.
This bill would make legislative findings to that effect.
