Mississippi: Lawyers Face Harsh Penalties for AI Errors

A federal judge in Mississippi has recently taken drastic measures by severely sanctioning attorneys for mistakes related to the use of artificial intelligence in their court documents. This decision comes after AI hallucinations were discovered in the filings, leading to the disqualification of attorneys from both parties involved in the case. The judge also imposed cumulative fines of $8,000 on the four attorneys involved, illustrating an increasingly firm stance by judges against AI errors in court filings.

American judges are showing signs of fatigue regarding errors caused by AI in their courts. A recent example of this growing impatience occurred in Mississippi, where a federal judge severely sanctioned the attorneys for both parties in a trial after they admitted to submitting court documents containing fictitious citations generated by AI.

In a sharply worded sanctions order published on Monday, U.S. District Judge Sharion Aycock removed the four attorneys from the case, prohibited two of them from practicing before the court for two years, and imposed cumulative fines of $8,000. The U.S. District Court for the Northern District of Mississippi "is once again 'tasked with addressing AI hallucinations in court filings,'" Aycock wrote in the 23-page order, adding: "This case presents the court with an unusual scenario: the attorneys for both parties engaged in similar sanctionable behavior."

The order reflects a growing frustration among American judges towards attorneys who file court briefs containing AI-generated errors, a legal expert told Business Insider. "In some previous examples of the same behavior, the offending attorneys were left with a mere reprimand," said Mark Bartholomew, a professor at the Buffalo School of Law. "Now, judges simply no longer believe when an attorney protests that they had no idea AI models can hallucinate, and they are willing to characterize this behavior as bad faith."

Aycock's sanctions stem from legal briefs filed by attorneys in a case involving a contractual dispute over legal fees between the plaintiff, Louisiana attorney Tom Withers, and the defendant, the Mississippi city of Aberdeen. According to the judge's order, Kathleen Wilson, an out-of-state attorney representing Withers, admitted to using an AI tool for legal research, while Kathryn Williams, an out-of-state attorney representing Aberdeen, acknowledged using generative AI to draft a filing. "Neither of them verified the legal authority produced by the AI before filing their briefs," Aycock wrote. The judge continued: "Their act of relying on AI's output without verification is sufficient to establish that they acted in bad faith."

Shauncey Ridgeway and Mark McClinton, the local attorneys for the plaintiff and defendant respectively, acknowledged that they had not reviewed the filings before they were submitted, according to the order. The four attorneys stated that they only learned that AI-hallucinated cases had been cited in their filings after the judge brought the issue to their attention late last year, according to Aycock's order, which indicated that the attorneys apologized and "expressed embarrassment."

This discovery led the court to suspend the case and cancel the scheduled trial. The attorneys' apologies did little to satisfy the judge. "In an era of unchecked rampant AI use in the legal field, this case presents a perfect example of the risk associated with acting as a mere rubber stamp as a local attorney," the judge wrote in her order on Monday.

Wilson and Williams received the harshest sanctions: two-year suspensions from appearing before the court and fines of $2,500 and $3,500, respectively. Ridgeway and McClinton were disqualified from the case and each fined $1,000. The judge gave Withers and the city of Aberdeen 60 days to find new attorneys.

Williams declined to comment, while the other attorneys did not immediately respond to requests for comment from Business Insider. A managing partner at Ridgeway's law firm, Christian & Small LLP, stated that the firm "will continue to educate our team on the proper use of artificial intelligence tools when they can benefit our clients, and on the absolute requirement that our attorneys verify that all information in our filings is accurate and correct."

Like many professions, the legal industry has rapidly adopted AI tools. According to the 2026 Legal Industry Report from the business platform 8am, 69% of legal professionals surveyed reported using generative AI tools for their work.

In recent months, attorneys in several cases handled by leading firms have come under scrutiny for their use of AI in the courtroom. Last year, law firms Ellis George and K&L Gates were ordered by a judge to pay approximately $31,000 in sanctions after attorneys filed a brief containing fictitious cases generated by AI. Earlier this year, an associate at the Wall Street law firm Sullivan & Cromwell apologized to a federal bankruptcy judge after submitting a court filing containing AI hallucinations.

Bartholomew, the law professor, stated that he expects more attorneys to be sanctioned by judges due to AI-generated errors. "The temptation is simply too great for overwhelmed attorneys looking for ways to cut corners," Bartholomew said, explaining that unless AI companies "solve the hallucination problem, there will be more of these cases and more sanctions."
