When Artificial Intelligence (AI) Goes Wrong: New York Court Sanctions Attorney for Citing a Non-Existent Case. Lessons for Motion Practice & Appellate Advocacy

📖 Case Summary: Grymes Dev. Co. v Fodera

In this Supreme Court, Richmond County case, the court addressed an increasing common issue: attorneys submitting legal briefs that rely on AI-generated “hallucinations.” The court sanctioned the attorney for citing one non-existent case and a supposed quote from the case.

⚡️ What Happened:

  • The third-party plaintiffs’ attorney moved for summary judgment in a title-insurance dispute concerning undisclosed encroachments on a residential property.
  • The attorney cited a case that did not exist in the memorandum of law. He also quoted language from the non-existent case, which was produced by an artificial intelligence (AI) too.
  • Opposing counsel identified the false citation, prompting the third-party plaintiffs’ attorney to apologize and attempt to withdraw the motion “withouut prejudice.”
  • Opposing counsel objected, arguing that they had expended significant resources to oppose the motion and that successive summary judgment motions are disfavored.

📝 Court’s Ruling:

  • The court agreed with the opposing counsel and concluded that the filing was frivolous under 22 NYCRR 130-1.1.
  • The court also concluded that the memorandum of law was filed without reasonable inquiry and was wasteful of judicial and party resources.
  • The court stated that the misuse of AI could not be excused as a mistake. It emphasized the growing issue of AI hallucinations in the law and reiterated that technology cannot replace an attorney’s independent professional judgment.
  • The court sanctioned the third-party plaintiff’s attorney and awarded the opposing parties attorney’s fees. It also denied the summary judgment with prejudice.

Key Legal Takeaways:

🔹 Frivolous Conduct:
New York courts are treating fabricated citations as frivolous conduct, requiring reimbursement of fees and imposing sanctions..

🔹 Denial of a Dispositive Motion:
Based on the research error, the court disallowed withdrawal of the motion and denied it. The court’s holding eliminated a major procedural tool for the third-party plaintiff, impacting litigation exposure, settlement posture, and coverage evaluations.

🔹 Increased Policing of AI Hallucinations by the Courts:
This case is one of multiple recent decisions that shows an increasing judicial intervention into improper AI-generated work.. See Augustin v Formula 3 Brooklyn Inc. and Mata v Avianca, Inc.

🔹 Attorneys Must Be Diligent of Legal Research Results Generated by Artificial Intelligence (AI):
Attorneys should verify all AI output with reliable legal research databases or the official reports. When legal filings are the product of more than one attorney, do not assume that the other attorneys have verified the cited cases and quotes.
