2 Oct 2026United StatesUnidentified legal research tool
On 2 October 2026 the Nebraska Supreme Court struck the appellate brief of a self-represented party appealing a contempt order in his divorce case because the brief contained numerous citations to fictitious cases and misstatements of law, which the court said were the result of his admitted use of generative artificial intelligence. The court held that self-represented litigants are held to the same standard as attorneys and that submitting a brief relying on nonexistent authority is an abuse of the judicial process worthy of sanctions. Citing the novelty of the issue for self-represented parties, it stopped short of dismissing the appeal and reviewed only for plain error, finding none and affirming the district court's contempt finding, its sanction of 90 days' incarceration with purge conditions, a temporary reduction of his parenting time and an attorney-fee award. The court warned that in future cases dismissal of the appeal may follow. The opinion does not name the AI tool.

Mar 2025United StatesJewish Onliner (suspected)
In March 2025 Yale placed a Yale Law School scholar, who was deputy director of a Yale Law School project, on administrative leave and barred the scholar from campus. The New York Times reports the decision came three days after a news site described as powered at least in part by artificial intelligence published a story on the scholar's connections to Samidoun, a group on a US sanctions list. Inside Higher Ed and Middle East Eye identify the site as Jewish Onliner. The scholar's lawyer says Yale's general counsel named the article as the trigger of the investigation. The scholar told the Times of not being a member of any organization that would violate US law, and the lawyer says the scholar is not a member of Samidoun. A Yale Law School representative told The National that placing an employee on temporary administrative leave while a review is conducted is the appropriate process and that the scholar's short-term position was due to expire the following month. The site says humans fact-check and that AI tools play a significant role in its work. The inspected sources do not show that AI produced the article.

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 2023VietnamUnidentified AI writing tool and Turnitin (reported)
In November 2023 a student at the Ho Chi Minh City University of Foreign Languages and Information Technology (HUFLIT) wrote on the university's anonymous confessions page that a writing-course essay had been returned with 50 percent of the marks deducted because the lecturer found it had been written with AI. The student said the lecturer had warned that AI-written essays would be treated as plagiarism if detected, had not expected detection, and learned from the lecturer that Vietnamese-to-English translation software could also be counted as AI use when checked with specialised plagiarism software; the student did not know whether the course could still be passed. The vice-rector told Tuoi Tre that the lecturer had told students before the assignment not to use AI applications, that the course tests independent writing, that using an AI support tool breached academic-integrity rules, and that the deduction was appropriate, while noting the university had no formal document on sanctions for AI use. A university representative told Thanh Nien and Dan Tri that the university does not ban AI but requires transparency about tools used, uses paid AI-detection services when necessary, and had not received a formal complaint from the student; a later report said the university had bought Turnitin licences for lecturers to check AI use in essays.
