Mercy Wellington v. City of New York
S.D. New York · Apr 30, 2026
What happened in this matter?
The Court issued a formal warning to a pro se litigant for including six AI-hallucinated, non-existent legal citations in an opposition brief. The Court declined to impose monetary or professional sanctions, citing the special solicitude afforded to pro se litigants, but explicitly warned that future misconduct would not be tolerated.
- Why the court cared
- The Court reasoned that while pro se litigants receive special solicitude, they are not excused from complying with procedural rules. It cited precedent establishing that submitting non-existent judicial opinions is improper and unacceptable. The Court determined that a warning was the appropriate response rather than sanctions, given the plaintiff's pro se status, while putting the plaintiff on notice that further misconduct would not be tolerated.
- Why it matters now
- This case illustrates judicial management of AI-generated hallucinations in pro se filings. It reinforces that courts expect rigorous verification of legal authority from all litigants and establishes that while courts may show leniency to pro se parties, they will formally document and warn against the use of fabricated citations.
Why this matter is tracked
In a civil rights action against the City of New York and various police officers, the plaintiff, appearing pro se, submitted an opposition brief containing six citations to non-existent legal authorities. The Court determined these citations were likely generated by an artificial intelligence tool. The Court emphasized that submitting fake legal authority is unacceptable, regardless of pro se status. While noting that sanctions are permissible for such conduct, the Court exercised its discretion to decline sanctions at this time, instead issuing a formal warning to the plaintiff that future misconduct would not be tolerated. The Court ultimately granted the defendants' motions to dismiss all claims.
