Daniel Gentry v. Calvin Thompson et al.
E.D. Louisiana · Mar 20, 2026
What happened in this matter?
The court sanctioned two attorneys for filing a motion containing nine AI-hallucinated case citations, violating Rule 11. The court imposed a $250 fine on the junior attorney and a $1,000 fine on the supervising attorney, while issuing a formal admonishment to the Chief Deputy City Attorney for the department's failure to verify legal research.
- Why the court cared
- The court reasoned that Rule 11 imposes an objective standard of reasonableness requiring attorneys to conduct a reasonable inquiry into the law. The court determined that relying on ChatGPT without verifying citations constitutes a violation of this duty. The court further reasoned that supervisors bear heightened responsibility for ensuring that subordinates read and verify every cited case, particularly when unusual formatting suggests potential AI generation.
- Why it matters now
- Require a second attorney to Shepardize every citation before filing; ChatGPT output without verification is automatic Rule 11 exposure.
