From a Minnesota Tax Court decision Thursday, Delano Crossing 2016 v. County of Wright (Chief Judge Jane N. Bowman and Judges Bradford S. Delapena and Beverly J. Luther Quast):
In support of a motion for summary judgment, which the court denies in a concurrent order, the County submitted a brief that included five case citations generated by Artificial Intelligence (AI); none of the five citations referred to an actual judicial decision. Indeed, much of the County's brief appeared to be written by AI. We subsequently ordered Wright County to show cause why it should not be sanctioned and why Ms. Pence, who signed and filed the brief, should not be reported to the Minnesota Lawyers Professional Responsibility Board. For the reasons below, although we believe Ms. Pence's conduct violated Rule 11, we decline to order sanctions. Additionally, we refer this matter to the Minnesota Lawyers Professional Responsibility Board for further review….
[When asked to explain the situation,] Ms. Pence generally characterized her filing of a brief containing AI-hallucinated case citations as a mistake, stating: "I believe I inadvertently filed a draft Motion that was never intended to be the final product. I did not intend to file an AI-generated pleading; however, I have been unable to locate any other documents containing my research."
Ms. Pence further averred that she did not realize her brief contained fake case citations until approximately 6:48 p.m. the night before the motion hearing, prompting Ms. Pence to conclude that the best time to deal with the situation was at the impending hearing. Ms. Pence further attested that although the case citations in her brief were fake, "the legal contentions in the motion are warranted by existing law as cited [orally during the hearing]." Ms. Pence generally attested, in other words, that although she "erroneously filed a document with hallucinated cases," the County's arguments were otherwise legally sound. Ms. Pence added that she has taken several remedial measures to ensure this does not happen again, and she understands "the seriousness of [her] mistake."
Rule 11.02 states that, "by presenting to the court … a pleading, written motion, or other document," an attorney certifies "to the best of [their] knowledge, information, and belief, formed after an inquiry reasonable under the circumstances" that "the claims, defenses, and other legal contentions therein are warranted by existing law…." "Thus, rule 11 prescribes an affirmative duty on counsel to investigate the factual and legal underpinnings of a pleading." …
