Keefe v. BMakin Film Ltd
SC New York · Apr 24, 2026
What happened in this matter?
The court issued a formal warning to the pro se defendant for submitting AI-generated legal papers containing fabricated case law and phantom quotes. The court explicitly characterized this conduct as frivolous under 22 NYCRR § 130-1.1 and denied the defendant's motion to vacate a default, stating that it would not consider filings based on fictitious authority.
- Why the court cared
- The court reasoned that submitting AI-generated documents with fictitious citations and quotes constitutes frivolous conduct under 22 NYCRR § 130-1.1, which wastes judicial resources and imposes unnecessary costs on opposing parties. The court rejected the defendant's pro se status as an excuse for such conduct, noting that the defendant had the option to present arguments via affidavit without relying on AI-generated fabrications.
- Why it matters now
- This case illustrates judicial intolerance for AI-generated hallucinations in pro se filings. It establishes that courts will treat the submission of fictitious legal authority as frivolous conduct, regardless of a party's pro se status, and may utilize formal warnings as a precursor to monetary sanctions.
Why this matter is tracked
In Keefe v. BMakin Film Ltd, the Supreme Court of New York addressed a pro se defendant's submission of a memorandum of law containing multiple fabricated case citations and phantom quotes generated by artificial intelligence. The court identified several specific instances of AI-generated hallucinations, including misattributed quotes and incorrect case citations that did not support the defendant's legal arguments. The court determined that the defendant's reliance on AI-generated fictitious authority constituted frivolous conduct under 22 NYCRR § 130-1.1. While the court found that sanctions were warranted, it opted to issue a formal warning to the defendant, noting that future submissions of AI-generated documents containing fictitious content would result in the imposition of monetary sanctions.
This case illustrates judicial intolerance for AI-generated hallucinations in pro se filings.
