Mullins v. Duquesne University of the Holy Spirit
W.D. Pennsylvania · Jul 15, 2026
What happened in this matter?
The Court denied the defendants' motion to strike, finding that the pro se plaintiff's use of Claude for drafting and editing did not result in sanctionable AI hallucinations. Although the Court acknowledged the plaintiff's brief was confusing and contained inapt citations, it determined the authorities were not fabricated or non-existent.
- Why the court cared
- The Court reasoned that sanctions for AI use are appropriate only when a litigant fails to review AI-generated content, resulting in fabricated citations or false information. Because the plaintiff's citations were decipherable and not non-existent, and the plaintiff certified he did not use AI to generate legal authorities, the Court found no sanctionable conduct.
- Why it matters now
- This case clarifies that inapt or confusing citations resulting from AI-assisted drafting do not automatically constitute sanctionable hallucinations, provided the authorities are real and the litigant has performed sufficient review.
Why this matter is tracked
Misrepresented: Case Law | Defendants pointed to lengthy multi-case string citations and other citations that did not directly support adjacent propositions; Court found such citations confusing or inapt but not false or fabricated. Outcome: Motion to strike denied. Defendants argued the pro se plaintiff's brief contained AI-generated inaccuracies, improper citations, and unintelligible phrasing suggesting reliance on generative AI. Plaintiff certified he used Anthropic's Claude for drafting and editing but not for generating citations or quotations. The Court reviewed cited examples (Phillips; Max's Seafood; Twombly; PBGC), found no fabricated or non-existent authorities and concluded the citations, while sometimes inapt or confusing, did not constitute sanctionable AI hallucinations. The motion to strike was denied and no sanctions were imposed.
This case clarifies that inapt or confusing citations resulting from AI-assisted drafting do not automatically constitute sanctionable hallucinations, provided the authorities are real and the litigant has performed sufficient review.
