California has enacted first-of-its-kind legislation governing attorneysâ use of generative artificial intelligence tools in their work, banning them from delegating the practice of law to AI and from entering confidential or personal information into an AI tool.
Gov. Gavin Newsom (D) signed the bill (SB 574) Wednesday to codify and expand on state court rules. It requires attorneys to verify all citations before filing briefs in court, including those generated by AI tools, and for at least one attorney to sign every court filing in their individual name, unless the party is representing themselves without an attorney.
The new law prescribes similar limits on arbitrators, barring them from delegating their decision-making process to AI tools and from relying on AI-generated information without disclosing it to the parties involved in the case. The law also sets parameters for courts to issue sanctions for violations.
Courts across the country have wrestled with attorneysâ increasing use of generative AI in their legal filings, often resulting in hallucinated or badly interpreted citations to prior case law. Among them, the California Tax Tribunal has considered whether to pass its own rules to govern AI use in the cases it hears. Just in the past two months, federal courts have warned or sanctioned attorneys in bias, bankruptcy, and Justice Department cases.
