Why this matter warrants attention
The court imposed a $250 monetary sanction on a pro se litigant for filing an appellate brief containing a fabricated case citation generated by unverified use of GenAI. The court held that such conduct is frivolous under 22 NYCRR 130-1.1, regardless of the litigant's pro se status or good-faith belief in the accuracy of the tools used.
The court reasoned that the submission of fabricated legal authority is frivolous conduct under 22 NYCRR 130-1.1(c)(1) because it lacks merit in law and asserts false material facts. The court rejected the appellant's pro se status as an excuse for failing to verify citations, noting that the sanction is necessary to deter future frivolous conduct and account for the waste of judicial and party resources.
This case confirms that New York appellate courts will impose monetary sanctions on pro se litigants for GenAI-induced hallucinations. It establishes that the duty to verify legal authority is a baseline requirement for all litigants, regardless of their representation status or reliance on automated research tools.
