Garner v. Kadince
CA Utah · May 22, 2025
What happened in this matter?
The court sanctioned Petitioner's counsel for filing a petition containing AI-generated fake legal precedent. The sanctions included an order to pay Respondents' attorney fees, a requirement to refund all fees charged to the client for the defective petition, and a $1,000 charitable donation.
- Why the court cared
- The panel (Per Curiam) emphasized that the conduct, while not malicious, still diverted judicial resources and imposed unnecessary burdens on the opposing party. Unlike Mata or Hayes, the attorneys in this case quickly admitted the issue and cooperated, which the court acknowledged. Nonetheless, the submission of fabricated law—especially under counsel's signature—breaches core duties of candor and verification, warranting formal sanctions. The court warned that Utah’s judiciary cannot be expected to verify every citation and must be able to trust lawyers to do so
- Why it matters now
- Ban unsupervised AI use by non-lawyer staff and require attorney review of every filing before submission.
Why this matter is tracked
Fabricated: Case Law | Fabricated appellate case cited in the Petition; opposing counsel showed it appears only in ChatGPT and not in any legal database, and the court sanctioned counsel for relying on fake precedent.
AI Use
The fabricated citations originated from a ChatGPT query submitted by an unlicensed law clerk at Petitioner's law firm. Neither Counsel reviewed the petition’s contents before filing. The firm had no AI use policy in place at the time, though they implemented one after the order to show cause was issued.
Hallucination Details
Chief among the hallucinations was Royer v. Nelson, which Respondents demonstrated existed only in ChatGPT’s output and in no official database. Other cited cases were also inapposite or unverifiable. Petitioner’s counsel admitted fault and stated they were unaware AI had been used during drafting.
Ruling/Sanction
The court issued three targeted sanctions:Attorney fees: Respondents’ counsel are to submit an itemized bill; Counsel must pay within 10 days of receiptClient refund: Petitioner’s counsel must refund all fees paid by Mr. Garner in relation to the defective petitionCharitable payment: Counsel must donate $1,000 to “and Justice for all” within 14 days and file proof of payment with the court
