Why this matter warrants attention
The court admonished counsel after discovering fabricated statutory language and non-existent citations in an opposition brief. The court suggested these errors resulted from the use of artificial intelligence without proper verification, reminding counsel of their independent duty to confirm the validity of all legal authorities under the Federal Rules of Civil Procedure and California Rules of Professional Conduct.
The court reasoned that counsel has an affirmative duty to read and confirm the existence of all legal authorities relied upon in filings. It noted that the quoted language from Cal. Gov't Code § 845.4 did not exist in the statute or any case law, concluding that the submission of non-existent authority constitutes an abuse of the adversary system and a failure to comply with professional conduct standards.
