Gauthier v. Goodyear Tire & Rubber Co.
E.D. Texas · Nov 25, 2024
What happened in this matter?
The court sanctioned attorney Brandon Monk $2,000, ordered him to complete one hour of CLE on generative AI, and required him to disclose the sanctions order to his client. The sanctions were imposed because Monk submitted AI-generated filings containing nonexistent cases and fabricated quotations, failing to perform the required independent verification under Rule 11.
- Why the court cared
- The court emphasized that attorneys remain personally responsible for the verification of all filings under Rule 11, regardless of technology used. Use of AI does not dilute the duty of candor. Continued silence and failure to rectify errors after opposing counsel flagged them exacerbated the misconduct
- Why it matters now
- Mandate a primary-source verification pass on every AI draft and require client disclosure when sanctions follow.

Hallucination Details
Cited two completely nonexistent cases. Also fabricated quotations attributed to real cases, including Morales v. SimuFlite, White v. FCI USA, Burton v. Freescale, among others. Several "quotes" did not appear anywhere in the cited opinions.
Ruling/Sanction
The court imposed a $2,000 fine, ordered Monk to complete at least one hour of CLE on generative AI in legal practice, and mandated formal disclosure of the sanctions order to his client. It also permitted amendment of the defective filing but warned of the severity of the misconduct.
