Evans et al v. Robertson et al (1)
E.D. Michigan · May 21, 2025
What happened in this matter?
The court issued a formal warning to a pro se litigant for citing nonexistent and misrepresented case law, which the court attributed to AI hallucination. The court struck the offending filings, ordered the litigant to comply with local and federal rules, and mandated a certification of citation accuracy for future filings.
- Why the court cared
- The court reasoned that the litigant violated Rule 11(b)(2) by presenting legal contentions not warranted by existing law. It noted that the cited case did not exist and that the citation provided actually referred to an unrelated Tenth Circuit decision. The court further observed that the misrepresentation of another case was nonsensical and likely AI-generated, concluding that such conduct wastes judicial resources and fails to meet the obligations of any litigant, regardless of pro se status.
- Why it matters now
- This case illustrates judicial scrutiny of AI-generated hallucinations in pro se filings. It establishes that courts will enforce Rule 11 obligations against unrepresented parties and mandate specific verification certifications when AI-assisted research produces fake authority.
Why this matter is tracked
In a civil matter, a pro se third-party litigant (John Doe) submitted filings containing fabricated and misrepresented case law. The court identified that Doe cited a nonexistent case, 'Navarro v. Sedgwick Claims Mgmt. Servs., Inc.,' which the court noted exhibited hallmarks of AI-generated hallucinations. Additionally, Doe misrepresented the holding of 'Strike 3 Holdings, LLC v. Doe.' The court struck the filings for violating Federal Rule of Civil Procedure 11(b)(2) and local formatting rules. The court issued a formal warning regarding the obligation to verify all citations and legal contentions, ordering Doe to file corrected objections with a certification that all citations have been verified for accuracy and applicability.
