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.

2024United StatesUnidentified voice-cloning tool (suspected)
While campaigning in 2024 for a Broward County court seat, Lauren Peffer, now a county judge, sought the endorsement of the South Florida Sun Sentinel editorial board. Asked to back her claim of an image crisis in Florida's judiciary, she cited a self-published book by a fired employee of the Ninth Judicial Circuit and supplied a recording purportedly of a phone call about the book between Chief Justice Carlos Muñiz, Justice Renatha Francis and the circuit's chief judge, Lisa Munyon. The Florida Judicial Qualifications Commission's notice of formal charges, filed in May 2025, said the recording was fabricated, likely using computer manipulation or generative AI, and that while the voices resembled those of the participants, the manner of speech, tone and much of the content were objectively unrealistic. The notice said she had shared it despite clear evidence of its inauthenticity and had perpetuated a false perception of illegal, unethical or immoral conduct by the justices, a chief judge and others in the judicial branch. Peffer apologised, said the content was created by a third party with whom she had no ties, and testified that she could not explain why she had thought it valid. According to Bloomberg Law, the Florida Supreme Court on 9 October 2026 suspended her for 30 days and fined her $10,000, saying her conduct undermined public confidence in the judiciary by implicating sitting justices; the two justices whose voices were faked recused. Who made the recording, and with what tool, is not reported.

An Ontario lawyer relied, at a 1 May 2025 Superior Court hearing in an estate and family-law matter, on a factum citing cases that do not exist or do not support the propositions cited. The judge ordered her to show cause why she should not be cited for contempt, then withdrew the order on 20 May 2025 after she said her staff had used ChatGPT without her knowledge. On 30 September 2025 she told the court that she alone had prepared the factum with ChatGPT and that her earlier account was untrue; the court referred the matter to Ontario’s Attorney General for criminal contempt proceedings in December 2025. In July 2026 the Law Society Tribunal suspended her licence for six months, finding she relied on AI-generated non-existent case law and lied about it. The account comes from legal-press and law-firm reports of the decisions; the criminal contempt case was still ongoing at the last report read.

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.
