1 Mar 2023 to 22 Jun 2023Event location unknownChatGPT
In a passenger's personal-injury suit against the airline Avianca in the US District Court for the Southern District of New York, an opposition brief filed on 1 March 2023 cited judicial opinions that did not exist. The court found that the lawyer who did the research had used ChatGPT, which fabricated the cases, and that when he asked the chatbot whether one of them was real it replied that it had supplied real authorities that could be found on legal databases. On 22 June 2023 the court found bad faith by the two lawyers, based on their conduct after the citations were questioned, and imposed a USD 5,000 penalty jointly on them and their firm, together with letters to the client and to each judge falsely named as an author of the fake opinions.

15 Dec 2025 to 1 Oct 2026CanadaUnidentified AI drafting tool
On 1 October 2026 the Quebec Court of Appeal ordered court costs against a self-represented appellant in a family-law contempt appeal as a sanction for appeal filings that, in the court's description, he had written with artificial intelligence and that contained two references to non-existent judgments and one inaccurate reference to a cited paragraph. The court held that AI may be used to draft appeal filings only if the litigant verifies the authorities, found that he had breached the Chief Justice's notice on AI use, and described his conduct as negligence rather than bad faith. It rejected the respondent's request for a separate $10,000 sanction and, for reasons unrelated to AI, reduced the contempt penalty imposed at first instance. The decision does not name the AI tool.

Event date unknownUnited StatesTurnitin AI-text detector (reported)
The University Press, Florida Atlantic University's student newspaper, reported on 29 September 2026 the accounts of two students who say they were penalised over AI-detection flags. A computer science sophomore submitted a paper 'last year' and received a zero after the professor flagged it for AI use after applying it to Turnitin; after the student emailed the professor, the grade was improved. The student says that when they ran the paper through a detector, it said the writing was overly human-sounding. A senior sociology major was accused of using AI on an essay and received a zero with little communication from the professor; after the student emailed to say no AI was used, the professor waived the penalty and gave a 50. The newspaper describes the second student's grade as due to a false AI detection and does not name the tool in that case. No professor's or university account of either case is reported.

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.

8 Oct 2025 to 2 Sept 2026IndiaUnidentified AI tool
On 8 October 2025 the Additional Commissioner of Customs in Surat imposed a penalty of ₹425,27,99,100 (about ₹425 crore) on a diamond trader under Section 114 of the Customs Act, 1962, for allegedly misdeclaring a consignment of natural diamonds as lab-grown diamonds to pay a lower tariff. The trader's challenge was dismissed by the Gujarat High Court on 20 January 2026. Before the Supreme Court the trader argued that judgments and articles cited in the penalty order had been generated using artificial intelligence. On 2 September 2026 a bench of Justices Dipankar Datta and Sheel Nagu, after checking the material, found that the order relied on case law that was non-existent or carried fake citations, and on real cases that did not lay down the propositions attributed to them, which the court said 'appears to be a hallucination of AI'. Holding that the use of AI and reliance on this dubious material was fatal to the order, the court set aside both the penalty order and the High Court's order without deciding the merits, sent the matter for fresh adjudication by a different officer of the same rank, and left any action against the order's author to the appointing authority. The AI tool used is not named in the read reports.

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.
