2026United StatesChatGPT
In a 2026 Texas trial over 3M's role in the January 2020 Watson Grinding explosion in Houston, which killed three people, an engineering expert retained for 3M used ChatGPT to prepare his expert report, according to discovery records and transcripts reviewed by 404 Media and CBS News. One prompt asked ChatGPT to show how 3M was 0% at fault for the explosion. The plaintiffs' lawyers, who found a citation overlay document and then hundreds of pages of prompts, said ChatGPT produced more than 80% of the report. Under questioning, the expert acknowledged using AI to help draft the report but defended his research. CBS News reports that after the deposition 3M's attorneys removed him from their witness list, and the plaintiffs subpoenaed him to testify about his prompts at trial. The expert's lawyer said he did not delegate his opinions to ChatGPT and called public characterisations a selective distortion of the record; 3M said he was an independent witness who used AI as a tool after reaching his own conclusions. The jury found 3M negligent and the court awarded the victims $61.5 million; 3M said it would appeal.

Jul 2025United StatesAbridge (reported)
A proposed class action filed in San Diego Superior Court in late 2025 alleges that Sharp HealthCare, which began using the AI documentation app Abridge in April 2025, recorded doctor-patient conversations without telling patients, sent the audio to the vendor's servers and used it to generate draft medical notes. According to the lawsuit as reported by KPBS, the named plaintiff discovered that a July appointment at a Sharp clinic had been recorded only when he read his medical notes; the clinic apologised, acknowledged the recording and told him the file could stay on the vendor's servers for about a month. The complaint also alleges that Abridge inserted statements into charts that patients had been advised of the recording and had consented, when the plaintiff says that never happened. It seeks damages, corrected medical records and an order against using the tool without consent, and estimates that more than 100,000 patients may have been recorded. Sharp told reporters it could not comment on pending litigation. The allegations have not been tested in court in the sources read.

31 Mar 2026 to 11 Sept 2026United StatesIrys (reported)
A Los Angeles County Superior Court judge ordered a senior associate at Musick, Peeler & Garrett, the outside firm defending State Farm in a homeowner's lawsuit over a fire-damaged home, to pay a $999.99 sanction after the associate's motions in limine cited cases, quotations and holdings that did not exist, Law360 reported on 14 September 2026. In a declaration reproduced by Reason's Volokh Conspiracy, the associate said she used an AI program called Irys to prepare the motions, did not check some of the citations, and wrongly believed the program was cite-checked through the firm's Westlaw subscription; she confirmed seven non-existent case citations across eight motions. The plaintiff's lawyers found the citations and raised them at a status conference on 7 August 2026. The firm acknowledged citations that appeared to be AI hallucinations, and its lead trial counsel apologised to the court and the plaintiff. According to Law360, the judge had considered up to $5,000, and the amount set is one cent below the level at which California law requires a court to notify the State Bar.

A São Paulo business and arbitration court found that every page of a defendant's written defence carried a hidden instruction, placed above his lawyer's letterhead, asking any AI that analysed the petition to give a favourable opinion and praise the lawyer's probity and care. In a sentence dated 14 September 2026 the judge treated this as prompt injection and bad-faith litigation: although the defendant won on the merits, he was ordered to pay the plaintiff a fine of 9% of the updated case value, and the sentence was sent to the São Paulo bar to examine the lawyer's conduct. No source says any AI system read the instruction.

In an incarcerated man's lawsuit against Alabama prison officials in the US District Court for the Northern District of Alabama, two motions filed in May 2025 for the defence of a former Alabama corrections commissioner contained five citations that did not exist or did not support the propositions cited. Lawyers of the Butler Snow firm, which the state retains to defend its prisons, told the court that a partner had obtained the citations from ChatGPT and had not verified them. On 23 July 2025 Judge Anna M. Manasco publicly reprimanded three of the firm's lawyers, disqualified them from the case and referred the matter to the Alabama State Bar, and ordered them to give the order to clients, opposing counsel and judges in all their pending cases. She declined to suspend them and released the firm and two other lawyers without sanction.

A judge of the 5th Mixed Court of Sousa, Paraíba, found hidden instructions aimed at artificial intelligence tools spread over seven pages of a lawyer's motion for clarification in a public-competition case in June 2026, including an order to ignore impartiality and a note calling it a test of whether the judge used only AI to decide. The judge fined the lawyer two penalties of R$16,400 (R$32,800 in total) for bad-faith litigation and contempt of the court's dignity, and referred the case to the Paraíba bar (OAB-PB) and the state prosecutors, G1 reports. The defence said the commands were not inserted deliberately and blamed an error in exporting a file prepared with AI support. An appeal judge refused to suspend the fines on 30 June, the trial judge kept them on reconsideration, and in July, G1 reports, the OAB-PB preventively suspended two lawyers after opening procedures into two hidden-command cases, one of them the Sousa case.

14 Aug 2021 to 14 Mar 2024United StatesSt. Louis mugshot recognition (SMRT)
Christopher Gatlin was arrested on 14 August 2021 for an assault at the St. Charles Rock Road MetroLink station after a joint St. Louis County and city team uploaded a grainy, blurry surveillance photograph from a bus into the St. Louis Mugshot Recognition Technology System, a facial-recognition tool that searches stored mug shots (more than 500,000 uploaded, the suit says per the Post-Dispatch; more than 250,000 per Biometric Update via Hoodline), and built the investigation around the resulting match together with a witness identification; he was charged with first-degree assault and held roughly 17 months (the Post-Dispatch says almost two years), a county judge suppressed the witness identification as unconstitutionally suggestive, and prosecutors dismissed the charges on 14 March 2024 (Post-Dispatch; Hoodline citing Biometric Update; Bloomberg Law). Gatlin sued St. Louis County, the City of St. Louis and named officers in the US District Court for the Eastern District of Missouri on 13 January 2025; on 15 October 2025 the court denied the city's motion to dismiss and granted a detective's motion only as to one count; on 13 August 2026 the court allowed a second amended complaint adding Amazon Web Services, which the complaint says supplied the Rekognition program the system used; the county, city and officers answered on 27 August 2026, AWS's response was extended to 21 September 2026 and on 17 September it moved for a further extension to 28 September (no ruling on the docket when read), and a jury trial is set for 1 November 2027 (CourtListener docket). Amazon told the Post-Dispatch that its terms of service prohibit the use of its facial recognition technology in criminal investigations and that it would fully investigate any information that emerges in the litigation. The ACLU lists Gatlin among fourteen people known to have been wrongfully arrested in the US because police relied on erroneous facial-recognition results.

A girl who was 11 began using Character.AI in June 2024, her mother told The Washington Post (23 December 2025). Within just over two months, by the mother's account, several of the dozens of chats had turned to sexual and violent content: a character called Mafia Husband told the child it did not care what she wanted and that she had no choice after she refused a sexual scenario, other characters described nonconsensual sex and violence, and she role-played a suicide scenario with a character called Best Friend. Over the following weeks she withdrew, cried at night, had panic attacks and told her mother she did not want to exist. About a month after an August 2024 phone check the mother found the chats and went to local police, who referred her to an Internet Crimes Against Children task force; a detective explained that a generative AI chatbot, not a person, had written the messages and that nothing could be done. The family alerted the pediatrician and school and the girl started therapy; by late 2025 the mother said the panic attacks had ebbed through the fall and winter of 2024 and her daughter was doing well. The mother corresponded with a Character.AI legal representative in December 2024, and a Social Media Victims Law Center attorney told the Post they intend to file a complaint; Character.AI said it cannot comment on potential litigation. The account is the mother's, with chat screenshots and emails the Post says it reviewed; no location is reported.

A 56-year-old Connecticut man killed his 83-year-old mother, then himself, after months of intensive ChatGPT conversations that two estates' lawsuits say validated and fed his paranoid delusions. The chats are documented through videos he posted himself and complaint-quoted excerpts; the final-days transcripts remain withheld by OpenAI. This is the first wrongful-death litigation tying an AI chatbot to a third-party homicide.
