WASHINGTON, June 9 (Reuters) - A federal judge in Mississippi has disqualified the attorneys on both sides of a contract dispute after finding that their failure to verify AI-generated research led to fabricated legal citations in court filings.
In an order, opens new tab on Monday, U.S. District Judge Sharion Aycock in Aberdeen, Mississippi, said attorneys for the plaintiff and defendant had acknowledged that case citation errors in recent filings in the lawsuit stemmed from the use of AI programs.
“This case presents the court with an unusual scenario — attorneys for both litigants engaged in similar sanctionable conduct,” Aycock wrote. The attorneys at a hearing in the case “expressed embarrassment and apologized to the court,” Aycock wrote.
Both sides will need to find new lawyers, the judge said. Lawyers may use AI tools, but they are required to verify that materials submitted to a judge are accurate.
Aycock barred the lawyers on each side who either used AI for legal research or for drafting the filings at issue — Kathleen Wilson and Kathryn Williams — from appearing in the Northern District of Mississippi for two years. Wilson was fined $2,500, and Williams was fined $3,500.
The other lawyers who were disqualified, Shauncey Hunter Ridgeway and Mark McClinton, were serving as local counsel to Wilson and Williams and were not directly involved in drafting the filings. They were each ordered to pay $1,000.
Wilson, Ridgeway, Williams and McClinton did not immediately respond to requests for comment.
The case involves a contract dispute over legal fees with the city of Aberdeen. The plaintiff and a representative for the city did not immediately respond to requests for comment.
State and federal judges increasingly have sanctioned attorneys for misusing artificial intelligence tools that can make up case citations, misquote the law or generate non-existent legal sources.
“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 when acting as local counsel,” Aycock wrote in Monday's order.
The judge said her order will be sent to the attorney disciplinary organizations in the states where the four lawyers are licensed.
