Judge Learns Lawyers on Both Sides of Case Used AI, Cancels Trial, Kicks Everyone Off the Case

A federal judge in Mississippi canceled a trial and disqualified all four lawyers involved after discovering that attorneys on both sides of a contractual dispute used artificial intelligence to generate court filings containing nonexistent, hallucinated legal citations. Senior U.S. District Judge Sharion Aycock issued sanctions including fines of $1,000 to $3,500 and two-year bans from her court, ruling that the lawyers wasted judicial resources by failing to verify AI-generated content. The case underscores growing judicial frustration with unverified AI use in legal practice, as courts nationwide increasingly penalize attorneys for submitting fabricated case law produced by generative AI tools.

The judge wrote in a blistering sanctions order, that the lawyers wasted the court’s time, and that “in an era of rampant unverified AI usage within the legal field, this case presents a prime example of the risk associated with serving as a rubber-stamp.” “This case presents the Court with an unusual scenario—attorneys for both litigants engaged in similar sanctionable conduct,” Sharion Aycock, senior United States District Judge for the Northern District of Mississippi wrote in a sanctions order. “This court is yet again ‘burdened with addressing AI hallucinations court filings.’” The case in question involved a contractual dispute between lawyer Tom Withers and the city of Aberdeen, Mississippi, over apparently unpaid legal fees Withers was not representing himself and was not sanctioned by the court . The case was first noticed https://x.com/RobertFreundLaw/status/2064189795128270931?ref=404media.co by Rob Freund, a lawyer who frequently posts about cases involving AI hallucinations. Freund called it a “comedy of AI errors,” and suggested “there were two clients who basically were paying for ChatGPT or whatever LLM to argue against itself.” 404 Media has repeatedly covered the phenomenon of lawyers using AI to prepare their filings, and the specifics in this court case follow a similar pattern to what we’ve seen before https://www.404media.co/18-lawyers-caught-using-ai-explain-why-they-did-it/ : Lawyers for both sides cited nonexistent, hallucinated cases while making their arguments. The difference is that every lawyer involved in the case is implicated, leading Aycock to pause the proceedings, cancel the trial, and disqualify all four lawyers involved. Two of the lawyers were barred from appearing before the court for two years; all lawyers received a fine of between $1,000 and $3,500, depending on Aycock’s assessment of their culpability for not verifying the outputs of the AI they used. Judges around the country have been increasingly frustrated with lawyers who use AI https://www.404media.co/lawyer-using-ai-fake-citations/ ; last week, for citing hallucinated cases in New York. https://www.404media.co/new-york-court-ai-citations-landberg-case/ we wrote about a judge who ripped into various lawyers This post is for paid members only Subscribe /membership/ Sign up for free access to this post Subscribe /signup/ Sign in /signin/
