Support Community v. MPH International
N.D. California · Oct 6, 2025
What happened in this matter?
The court sanctioned counsel for filing a brief containing AI-generated fabricated case law. The court ordered the re-filing of the motion without the hallucinated citations, awarded the opposing party reasonable attorneys' fees and costs, and required counsel to self-report the misconduct to the State Bar of California and provide a copy of the order to the client.
- Why the court cared
- The court reasoned that Rule 11(b)(2) imposes an objective duty on attorneys to read and verify the existence and validity of all legal authorities cited in filings. By failing to verify AI-generated citations, counsel breached this duty, necessitating sanctions to deter future misconduct and compensate the opposing party for time diverted to address the fabricated authorities.
- Why it matters now
- Multiple fabricated cites in one brief forces bar and client notification — mandate partner sign-off on all authorities before filing.
