Cojom v. Roblen

D. Connecticut · Nov 17, 2025 · Janet C. Hall

Direct answer

What happened in this matter?

The court imposed a $500 monetary sanction on attorney David P. Stich for violating Rule 11 by filing a brief containing fabricated legal citations generated by the AI tool Descrybe.AI. The court determined that the attorney failed to perform a reasonable inquiry into the accuracy of the cited authorities before submission.

Why this matter is tracked

Fabricated: Case Law | Court could not locate case Outcome: Monetary sanction. "The danger of Attorney Stich’s AI use is especially felt here because his opponent’s pro se status meant that there was not an adversary capable of calling the attention of the court to the phony citations. Furthermore, this court expended time and resources in investigating the hallucinated citations, resources that could have been better spent adjudicating the merits of this underlying litigation and that of other cases pending before this court. The oversight in submitting fake citations is more than just sloppy lawyering: it imperils the integrity of our judicial process.However, the court also acknowledges that our society sits on the precipice of rapid technological development and that the continued development of AI will fundamentally alter life as we know it. Just as the advent of the Internet in the late 20th century transformed the legal profession, and particularly legal research, so too will artificial intelligence. Indeed, the two biggest legal research databases, Westlaw and LexisNexis, have developed and continue to expand their own proprietary AI tools to assist legal practitioners in finding case law.2 This Order should not be construed as a Luddite attack on technology and the efficiency it brings to the legal profession. Rather, this Order is an acknowledgement that AI remains a nascent technology with questionable reliability at this juncture. Given the ethical obligations lawyers must honor, it is imperative that lawyers use AI with diligence and care. This technology is too unsophisticated and must necessarily yield to a lawyer’s obligation of candor to the court."
