Fee suit against the City of Aberdeen (N.D. Miss.): four attorneys on both sides sanctioned after AI tools produced fabricated case citations; trial cancelled and both litigants left without counsel
In a fee dispute between a Louisiana attorney and the City of Aberdeen, Mississippi, briefs filed for both sides in late 2025 cited six cases that do not exist. The attorneys admitted the citations came from unverified AI use: the plaintiff's out-of-state counsel, Kathleen M. Wilson, drafted her filing with an AI drafting program called 'First Drafts', and the City's out-of-state counsel, Kathryn Y. Williams, used an in-house AI legal research tool. Senior Judge Sharion Aycock stayed the case and cancelled the March 2026 trial, then on 8 June 2026 revoked both attorneys' pro hac vice admissions, barred them from the district for two years and fined them $2,500 and $3,500, and disqualified and fined the two local counsel who had signed the filings. Both litigants were left without counsel and given 60 days to find new representation.

AI system as recorded: 'First Drafts', an AI-powered legal drafting program (plaintiff's counsel), and an unnamed in-house AI legal research software product (City's counsel); underlying models not stated
What Happened
The plaintiff sued the City of Aberdeen for breach of contract over legal fees. After the City moved for summary judgment on 5 November 2025 and challenged the plaintiff's fee accounting, the court could not locate several authorities in the briefs: one invented Mississippi Supreme Court case in the City's summary-judgment memorandum, three invented Northern District of Mississippi decisions in its fee-challenge memorandum, and two invented cases in the plaintiff's opposition. On 10 December 2025 the court ordered all four counsel of record to show cause. Both sides then sought leave to file corrected memoranda and admitted the citations resulted from unverified AI use. At the 20 January 2026 hearing, Wilson, a Louisiana solo practitioner, said she had used 'First Drafts', an AI-powered drafting program, for about six months and had not verified its output; the plaintiff's corrected-filing motion disclosed further misstatements of law, including a fake quote, in other filings she drafted. Williams, a Texas partner, said her firm had acquired AI legal research software about ninety days earlier; the court found she knew it was not designed for Mississippi law and that she disregarded her firm's own policy requiring verification. The court found both acted in bad faith. The two Mississippi local counsel, who did not use AI and were unaware of their co-counsel's use, admitted that the filings bore their signatures although they had not reviewed the citations and self-reported to the Mississippi Bar. The court stayed the case on 4 February 2026 and cancelled the trial, noting later that the tainted filings kept it from resolving the dispositive motion. The 8 June 2026 sanctions order imposed pro hac vice revocation, a two-year bar and fines on the two drafting attorneys, disqualification and $1,000 fines on local counsel, referral to three state bars, and left both litigants to find new counsel within 60 days. The court also recorded that a bankruptcy court in Louisiana sanctioned Wilson in April 2026 for AI-generated nonexistent authorities filed after the January hearing, and that Williams had misrepresented a scheduling conflict to avoid appearing in person.
Reported harm
Per the court's orders, two attorneys who filed AI-generated fabricated citations lost their pro hac vice admissions, were barred from the district for two years and fined $2,500 and $3,500; two local counsel who signed the filings were disqualified and fined $1,000 each; the case was stayed with its trial cancelled, and the plaintiff was left without counsel under threat of dismissal.
Outcome
OngoingStay order, 4 February 2026 (ECF 120): case stayed, pretrial conference and 23 March 2026 trial cancelled, pending motions terminated. Sanctions Order, 8 June 2026 (ECF 123): Wilson and Williams pro hac vice revoked, two-year bar from the Northern District of Mississippi, fines of $2,500 (Wilson) and $3,500 (Williams), AI ethics CLE for Wilson; Ridgeway and McClinton disqualified and fined $1,000 each; order sent to the Mississippi, Louisiana and Texas bars; stay continued 60 days for the litigants to find new counsel by 7 August 2026, failing which the plaintiff's case would be dismissed. Order of 17 August 2026 (ECF 133): after a contempt show-cause over non-payment, Wilson's deadline to pay and complete the CLE extended to 16 September 2026.
What remains unknown
- Which underlying model the 'First Drafts' program and Williams' research tool used; the order names neither vendor's model.
- Whether the Mississippi, Louisiana or Texas bars opened disciplinary proceedings, and whether Wilson paid by 16 September 2026.
- Whether the litigants retained new counsel by 7 August 2026 and what became of the case.
- The dates of the other tainted filings Wilson drafted in this case (ECF 123 p.11); they may predate 5 November 2025.
What the evidence supports
AI involvement: supported. The sanctions order records the two drafting attorneys' admissions that their filings were produced with AI tools (Wilson: 'First Drafts', a generative drafting program; Williams: an unnamed in-house AI legal research product) and finds that their unverified reliance on the output produced the fabricated citations.
5 claims: 5 documented. What the statuses mean
Documented In late 2025, legal memoranda filed for both sides in a fee suit against the City of Aberdeen (N.D. Miss.) cited cases that do not exist; the court identified one such citation in the City's summary-judgment memorandum, three in its fee-challenge memorandum and two in the plaintiff's opposition, and the attorneys admitted the citations resulted from unverified AI use.
Causal attribution. Established by the court's sanctions order on the attorneys' own admissions.

p. 2: 'the Court was unable to locate certain legal authorities cited within them. Specifically, the Court determined that the following filings contained hallucinatory citations'; p. 3: 'the attorneys admitted that the hallucinatory citations cited by them, and identified by the Court, resulted from unverified AI use.'

p. 3: 'Williams admitted to using an AI tool to conduct legal research, and Wilson admitted to using generative AI to draft her respective filing. Neither of them verified the legal authority output by AI before filing their briefs.'; p. 9: 'She explained that she used “First Drafts,” an AI- powered program for drafting legal documents.'; p. 14: 'it had acquired software that was built for in-house legal research.'
Documented On 8 June 2026 the court revoked Wilson's and Williams' pro hac vice admissions, barred both from appearing in the Northern District of Mississippi for two years, fined Wilson $2,500 and Williams $3,500, ordered Wilson to complete an AI ethics CLE, disqualified the two local counsel (Shauncey Hunter Ridgeway and Mark C. McClinton, who signed without checking the citations) with $1,000 fines each, and sent the order to the Mississippi, Louisiana and Texas bars.
Causal attribution. The sanctions are the court's response to the AI-generated false citations and the failure to verify them.

Documented Because of the sanctions issue the court stayed the case, cancelled the pretrial conference and the 23 March 2026 trial, and terminated the pending summary-judgment and fee motions; after disqualifying all four attorneys it gave both litigants 60 days to find new counsel, acknowledging this could cause them hardship, and warned the plaintiff that the case would be dismissed if no counsel appeared or he did not elect to proceed pro se by 7 August 2026.
Causal attribution. The stay and loss of counsel follow directly from the sanctions proceeding over the AI-generated citations, per the court's orders.

Massachusetts federal court revokes an out-of-state lawyer's admission and orders fees after briefs with false citations; the lawyer admitted AI drafted one
On 25 September 2026 a judge of the U.S. District Court for the District of Massachusetts granted a defence motion for sanctions under Federal Rule of Civil Procedure 11 against a California-barred lawyer admitted for one case (pro hac vice) to represent the plaintiff. The court found that an opposition the lawyer filed on 21 November 2025 was replete with inaccurate citations, including a quotation attributed to a case with a fictitious Westlaw citation, and that later oppositions cited a non-existent case. In response to the court's order to show cause, the lawyer admitted using AI to draft the first opposition and explained a belief that the enterprise-level AI software in use did not hallucinate cases. The court revoked the lawyer's pro hac vice admission and ordered the lawyer's firm to pay the defendants' reasonable fees and costs, capped at $10,000. The order does not name the AI product.
New Mexico Supreme Court fines attorney Stephen Aarons $5,000 and removes him from a murder appeal over ChatGPT-fabricated testimony
Santa Fe defense attorney Stephen Aarons used ChatGPT (OpenAI's o3) on a Rev.com transcript and the record to draft briefing in the murder appeal of Oscar Renee Sandoval; the brief contained fabricated witnesses and testimony (including police officers 'Michelle Amarillo' and 'Sanchez' and invented testimony attributed to real people) and misdescribed real precedents. After a 21 August 2026 show-cause hearing at which Aarons admitted he had not verified the output, the New Mexico Supreme Court's written order of 9 September 2026 held him in direct contempt, fined him $5,000 payable to the State Bar Client Protection Fund within 30 days, removed him from the case, barred him from appearing before the court pending a disciplinary-board referral, struck the filed briefs and reassigned the appeal to the public defender.
Ninth Circuit fines and suspends two immigration lawyers over briefs with AI-hallucinated citations and denials of AI use; immigration board follows
On 3 June 2026 the US Court of Appeals for the Ninth Circuit fined immigration attorneys Mike Singh Sethi and William Rounds $2,500 each and suspended both from practice before the court for six months. Briefs filed in an asylum petition for review cited two cases that do not exist and attributed quotations to opinions that do not contain them. In a motion to correct, the attorneys called the errors typographical, and at oral argument Rounds twice said AI was not used. In their response to the court's order to show cause, they conceded that the errors were probably the product of unauthorised AI use by the firm's unlicensed brief writers and a failure to check citations. The court said the suspension was owed to their repeated failure of candour. The Board of Immigration Appeals then suspended Sethi from practice before the Board, the immigration courts and the Department of Homeland Security for six months, effective 13 June 2026, and designated that decision as a precedent on 1 October 2026.
Alabama Supreme Court dismisses two siblings' family-trust appeal as a sanction after their lawyer admits using AI that produced fake citations
On 24 April 2026 the Supreme Court of Alabama dismissed an appeal by two siblings in a family dispute over living trusts because their lawyer, W. Perry Hall, had filed briefs in which most of the legal authorities were misquoted or did not exist. The court said they appeared to be AI hallucinations, and at a show-cause hearing in February 2026 Hall admitted that many authorities did not exist and that he had improperly used AI to obtain them. The court ordered Hall to pay the opposing party's fees and costs of $17,200 and double appeal costs, barred him from filing in the court without a co-signing attorney and referred him to the Alabama State Bar. It said the dismissal was imposed as a sanction because of the particularly egregious facts. One justice, concurring in part and dissenting in part, objected to dismissing the appeal as a sanction for the lawyer's conduct but would have affirmed the judgment against the clients on the merits.
