Dec 2023 to Mar 2024United StatesGrammarly (reported)
In late 2023 a junior at a public high school in Hingham, Massachusetts, and a classmate submitted a script for an AP U.S. History project that, a federal court later found on a preliminary record, contained text copied from Grammarly, a publicly available AI tool, including citations to nonexistent books, with no acknowledgement of AI use. Turnitin and other AI detection tools had flagged the script, and a school official says the pupil admitted using Grammarly. In December 2023 the school treated it as cheating: the pupil failed two parts of the project, served a Saturday detention and was rejected from the National Honor Society in spring 2024, though he was later admitted. His parents sued, arguing the school had not made its AI rules clear; on 20 November 2024 the US District Court for the District of Massachusetts refused a preliminary injunction to undo the penalties, and in February 2025 the parties dismissed the case with prejudice.

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.

1 May 2025CanadaChatGPT
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.

Aug 2024South KoreaUnidentified image tool
On 16 September 2026 the Incheon District Court sentenced a teenage defendant to an indeterminate term of two years (maximum) to one year six months (minimum) under the Sexual Violence Punishment Act for making and distributing false sexual images, ordered a 40-hour treatment programme and a five-year ban on working with children, and took him into custody in court. As a middle-school student in Incheon in 2024 he had used AI deepfake technology to composite the faces of five teachers, including his homeroom teacher whom he tricked into sending photographs, and six female middle- and high-school students from his taekwondo academy onto nude images and videos, 35 productions in all, and distributed them in Telegram 'acquaintance humiliation' chat rooms with the victims' real names, ages, schools, subjects and, per two reports, phone numbers (Hankook Ilbo adds Instagram IDs on some). The teachers learned of the images only in January 2026; the court said they are receiving long-term psychological treatment. He had withdrawn from school a week before the teachers'-rights committee met, avoiding school discipline. The Incheon teachers' union called the sentence, below the prosecution's request, regrettable.
