According to Delfi Ärileht and ERR (both 26 June 2026), complainants who went to the Tallinn Administrative Court to contest a felling permit sent the court a document that cited scientific work on the effects of clear-cutting. The court found that the Estonian scientists named in the references do not exist and that the studies described could not be found. It asked the complainants how the document had been produced, gave them the chance to submit the cited works, and warned that it could fine them for attempting to mislead the court. The complainants replied that using AI is not forbidden and that they had not meant to mislead the court. The court fined one complainant 150 euros and nine others 50 euros each, saying that complainants are responsible for the accuracy of what they submit. Delfi Ärileht reports that the Tallinn Circuit Court agreed with the administrative court and that the Supreme Court declined the case that week, so the fines are in force.

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.

In November 2025 Stephens County Associate District Judge Lawrence Wheeler issued an order in a child paternity and custody case that denied one parent's request for a psychological evaluation of the other parent and reprimanded the requesting parent's attorney 'for stooping to such frivolous trial tactics'. The attorney challenged the order at the Oklahoma Supreme Court in February 2026, telling the justices that it relied on two cases that do not exist; the challenge was dismissed in March after Wheeler vacated the order, and he is no longer on the case. According to a 17 August 2026 letter from the Stephens County district attorney, Wheeler told the Oklahoma State Bureau of Investigation that he used ChatGPT for research and wrote the order himself, and that at least two citations in it produced by ChatGPT do not exist. The mother in the case told News 9 that learning the order's citations were allegedly fabricated was alarming because it concerned the custody of a child. The attorney general's office declined criminal prosecution; judicial discipline remains possible.

On 25 August 2026 the Solicitors Disciplinary Tribunal struck Abhishek Kumar off the Register of Foreign Lawyers after finding proved that his 12 March 2026 Answer to the SRA's Rule 12 Statement contained misleading quotations and citations produced with generative AI — including a non-existent 'SRA v Chan [2020] EWHC 1502' and a miscited 'SRA v James, MacGregor & Naylor [2018] EWCA Civ 1420' that is actually an intellectual-property case — and that his 9 April 2026 email admitting AI use was itself AI-drafted with further errors. The tribunal said it would have struck him off on that allegation alone; the parallel ground was his January 2024 conviction under s.21 of the Immigration, Asylum and Nationality Act 2006. This is the SDT's first case on a lawyer's use of AI, per the SRA's counsel.

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.
