What the record shows
The court found that defense counsel's unverified use of AI produced false citations in the Opposition, with errors involving quotations that did not exist in the cited cases and altered citations. Sanctioning under 28 U.S.C. section 1927, the court ordered the firm Luther & Lanard, PC to pay 50% of Plaintiffs' fees for responding to the false citations, totaling $2,418.50, to Plaintiffs' counsel within 10 days, and to notify the California State Bar and file a declaration of compliance.
This entry reflects the court document as filed. The citations at issue could not be located in the reporters named at the time of the order. The reading here is descriptive of the public record and is not legal advice.

The test this filing did not run
Every matter in this record shares one mechanism: a citation that did not resolve to an opinion in the reporter named, in a brief that was filed before any verification step ran. Veritas runs that step. The Filing Risk Scanner extracts each citation, resolves it against reporter and public-record sources, and returns a verdict on each one — located, partial, or not located in reporter — before the brief is signed.
