TLDR: The California Judicial Council has formally adopted new rules, effective September 1, 2025, governing the use of generative artificial intelligence (AI) within the state’s legal system. These regulations, the first comprehensive framework of their kind in the nation, aim to balance technological innovation with core judicial values, mandating strict policies for confidentiality, impartiality, and accountability while prohibiting AI from critical adjudicative functions like interpreting evidence or issuing judgments.
SAN FRANCISCO, CA – In a pioneering move set to reshape the landscape of legal technology, the California Judicial Council has formally approved a new rule and standard for the use of generative artificial intelligence (AI) across its extensive court system. Effective September 1, 2025, Rule 10.430 and Standard 10.80 establish the nation’s first comprehensive framework for AI application in court operations, aiming to strike a crucial balance between fostering innovation and upholding the foundational principles of confidentiality, impartiality, and public trust in the justice system.
The decision, made on July 18, 2025, by the Judicial Council, which oversees California’s 65 courts and approximately 1,800 judges handling roughly five million cases annually, comes amidst a global surge in AI adoption and growing concerns over its ethical implications in sensitive sectors. Chief Justice Patricia Guerrero established the Artificial Intelligence Task Force in 2024, which developed these rules in response to increasing public anxiety regarding AI’s impact, including high-profile incidents of AI-generated ‘hallucinations,’ discriminatory outputs, and data breaches in legal contexts.
Justice Brad Hill, chair of the Artificial Intelligence Task Force and with the state’s Fifth Appellate District, emphasized the need for a balanced and adaptable framework. The new regulations neither mandate nor prohibit AI use but provide clear guidelines. They distinguish between a ‘rule’ for court staff and judges using AI outside an adjudicative role, and a ‘standard’ for judges in adjudicative situations, though both share many core principles.
Key provisions of the new framework include:
Permissible AI Uses: AI tools can assist with tasks such as legal research, procedural form generation, and drafting memos.
Prohibited AI Uses: Generative AI is strictly forbidden from interpreting evidence, issuing judgments, or accessing sealed documents. It must not be used to impose bias or discrimination. Furthermore, confidential or sensitive information, such as driver’s license numbers, must not be inputted into public AI systems, as ‘anything a user inputs into the system is often used to train the system,’ according to Justice Hill.
Mandatory Disclosures: Judges and legal staff are required to disclose when AI has been used in court documents or decisions, particularly for visual, written, or audio content that is publicly accessible and where AI played a role in its creation. When used by a judge in an adjudicative role, they should consider if a disclosure noting AI use is needed for publicly available documents.
Human Oversight and Verification: Users must rigorously review and correct any errors made by AI, including ‘hallucinations’ or false information like fake case citations. Human judgment remains paramount, reinforcing the idea that AI should be assistive, not authoritative.
Courts that choose to permit AI use must adopt a specific usage policy by December 15, 2025, with the option to either adopt a model AI policy provided by the Judicial Council or tailor their own regulations to meet local needs. This flexibility is crucial given the rapid evolution of AI technology.

California’s proactive stance is expected to set a national precedent, influencing judicial AI policies across other U.S. states as legal institutions navigate the swift incorporation of artificial intelligence into their processes. Legal experts predict this move will establish a critical balance between digital efficiency and ethical responsibility, ensuring that the integrity and fairness of the judicial system are preserved in the digital age.
