21 Oct 2025 to 3 Apr 2026United StatesCoCounsel
In a published opinion of 3 April 2026, the U.S. Court of Appeals for the Sixth Circuit addressed the briefs a lawyer appointed under the Criminal Justice Act had filed for an indigent defendant appealing a sentencing enhancement in a drug-trafficking case. The court noticed that the principal brief's file name was 'CoCounsel Skill Results' and found three quotations that appear in no legal authority and misstatements of two precedents. The lawyer admitted that a staff member had used Westlaw's CoCounsel to create the first draft, that he repeated the process for the reply, and that the false quotations came from artificial intelligence he did not verify. The court denied him compensation for the appeal, referred the opinion for possible disciplinary proceedings and to the Kentucky Bar Association, and by separate order removed him, locked his briefs and ordered replacement counsel to file new ones, which it said further delayed resolution of the defendant's appeal. The court acknowledged his candour and his 40 years without discipline.

31 Jan 2025 to 12 Dec 2025United StatesUnidentified AI drafting tool
On 12 December 2025 the U.S. District Court for the District of Oregon dismissed with prejudice the claims of plaintiffs in a family dispute over their late mother's estate and family property, as a sanction for what the court called their misuse of generative artificial intelligence, and found their continual violations of the court's Local Rules an additional basis for the dismissal. Three of the plaintiffs' summary-judgment briefs cited fifteen nonexistent cases and fabricated quotations attributed to eight real authorities. The plaintiffs had said the inaccurate citations came from reliance on an automated legal citation tool. The court found that the plaintiffs shared responsibility with their lead lawyer and that one plaintiff, a frequent self-represented litigant, was likely the person who used AI to draft the briefs. It struck the briefs, ordered the lead lawyer to pay $15,500 to the court and awarded the defendants their fees. In March 2026 it set those fees at $94,704.38, ordering the lead lawyer to pay 85% and local counsel 15%. In June 2026 it denied the plaintiffs' motion to reconsider a later ruling for the defendants on a counterclaim.

Feb 2025Event location unknownMeu INSS app
In February (2025, inferred from the article date) a retirement claim filed through Brazil's Meu INSS social security app for a former sugarcane worker in northeast Brazil was rejected. Rest of World reported that the request was turned down because the system identified the claimant as a man. The claimant, who has chronic illnesses, is quoted saying the benefit is still denied despite complete documents, and Rest of World reports that minor errors in earlier claims through the app had led to numerous rejections. The retirement claim was approved in March after INSS directors corrected the mistake, which the claimant attributed to a contact at an agricultural workers' confederation. The INSS states that automated decisions follow specified legal criteria.

In an August 2025 first-person post, a student said they discovered a zero for a summer-course discussion assignment after a checker labelled 85% of the text AI-generated. They denied using AI to write it, reported contacting the professor, and described anger and fear of future accusations.

Apr 2025 to May 2025Event location unknownCoCounsel, Westlaw Precision and Gemini (reported)
In an order dated 5 May 2025 and filed on 6 May in Lacey v. State Farm (C.D. Cal.), a special master struck the claimant's supplemental briefs and denied the discovery relief she sought after her lawyers filed briefs built on unverified AI-generated legal research: about nine of 27 citations were wrong and at least two cited authorities did not exist. One lawyer's sworn declaration says the outline he circulated relied on generative AI features in CoCounsel, Westlaw Precision and Google Gemini, and that he could not tell whether particular errors came from his transcription or from a tool; co-counsel at the second firm say they used no AI tools and did not know AI had been used. The order makes the two firms jointly pay $31,100, states the client was not at fault and will not bear the awards, and imposes no penalty on individual lawyers.

Nov 2025United StatesChatGPT
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.

24 May 2025 to 27 Jun 2025Event location unknownGoogle AI Overviews
An author and television producer, the subject of the Apple TV series 'Black Bird', sued Google, alleging that AI Overviews shown for searches about him in May and June 2025 falsely said he was serving a life sentence without parole, in one version for the murders of three women. He says he notified Google three times and received apologies attributing the statements to its AI, yet similar statements kept appearing. On 14 September 2026 the Northern District of Illinois denied Google's motion to dismiss as to two of the four challenged Overviews and dismissed the other two without prejudice. This was a ruling on the pleadings, not a finding that the allegations were proven.
