What was fabricated or misused
- Royer v. Nelson, 2007 UT App 74, 156 P.3d 789 — AI “hallucinated” case that did not exist anywhere other than ChatGPT
- Other citations and quotations in the petition appeared AI-generated or wholly unrelated; the opinion did not enumerate them
What the court said
“As the primary example, Respondents’ counsel pointed to the citation to “Royer v. Nelson, 2007 UT App 74, 156 P.3d 789” as an AI “hallucinated” case that does not exist anywhere other than on ChatGPT.”
“Petitioner’s counsel acknowledged that the Petition contained fabricated legal authority, which was obtained from ChatGPT, and they accepted responsibility for the contents of the Petition.”
“However, we emphasize that every attorney has an ongoing duty to review and ensure the accuracy of their court filings.”
“Opposing counsel cannot be required to independently verify the veracity of each citation in another’s court filings.”
Timeline
- Order-to-show-cause hearing held before the Utah Court of Appeals.

- Per curiam opinion found a rule 40 violation and imposed sanctions.
Why this case matters
The Utah appeal is a state appellate counterpart to Park v Kim and Gauthier. It involved a law clerk's ChatGPT use, not a lawyer typing the prompt, yet the signature still certified that the legal contentions rested on existing law. The court distinguished cases such as Mata, where lawyers persisted longer, and set sanctions that repaired case-specific harm: fees for the response, client refund and a legal-aid donation. The record helps separate negligent supervision from later concealment.
Practice note
Before signing an appellate petition, the attorney of record should verify each cited case in an official reporter or database and confirm that quoted language exists. Firms also need an AI policy for clerks and paralegals before filings are drafted, not after an order to show cause. Rule 40 treats the signature as the certification.
