On 1 December 2025 the presiding judge of a chamber of the Czech Constitutional Court fined a Prague lawyer 25,000 crowns (a quarter of the statutory maximum) for grossly obstructing proceedings. The lawyer had filed a constitutional complaint, for a client refused a temporary residence permit, that argued from 12 decisions of the Constitutional Court and the European Court of Human Rights; the court found that a substantial part of them did not exist and part were grossly misinterpreted. The order says the complaint showed signs of generative AI and that the court presumed the lawyer had generated it with an AI model and then failed to verify the citations. The lawyer confirmed to INFO.CZ that an AI tool was used, described it as a paid professional model from a legal information system provider, said the output was not checked enough, and expressed regret. The court invited the client to correct the complaint so that the client would suffer no procedural harm; the complaint was later rejected as manifestly unfounded on 30 January 2026. INFO.CZ reported on 10 December 2025 that the lawyer had apologised and paid the fine and that the Czech Bar Association's supervisory board was examining the case.

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.

In October 2025 Swedish media, citing Finansinspektionen, reported that more than 5,000 small savers had lost about half a billion kronor that year in pump-and-dump share frauds, and a Finansinspektionen official said some had lost several million kronor. An investigator at the Economic Crime Authority told TT that the frauds, run from abroad, use a refined method with the latest AI technology. TV4 described the usual pattern as a Facebook tip in which a well-known finance profile appears to recommend a safe investment, leading to a WhatsApp group. The investor Günter Mårder said 30 to 40 adverts and AI-produced films showed him speaking, that about 15 to 20 finance profiles had been used, and that his whole summer went on handling questions. Sveriges Radio reported that the financial journalist Gabriel Mellqvist's identity had been used and that he was frustrated at the damage to his professional reputation and at Meta's inaction. The authority does not say how the AI use was established, and the savers figure is not tied to the AI adverts.

On 25 September 2026 a judge of the U.S. District Court for the District of Massachusetts granted a defence motion for sanctions under Federal Rule of Civil Procedure 11 against a California-barred lawyer admitted for one case (pro hac vice) to represent the plaintiff. The court found that an opposition the lawyer filed on 21 November 2025 was replete with inaccurate citations, including a quotation attributed to a case with a fictitious Westlaw citation, and that later oppositions cited a non-existent case. In response to the court's order to show cause, the lawyer admitted using AI to draft the first opposition and explained a belief that the enterprise-level AI software in use did not hallucinate cases. The court revoked the lawyer's pro hac vice admission and ordered the lawyer's firm to pay the defendants' reasonable fees and costs, capped at $10,000. The order does not name the AI product.

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 State Department cable dated 3 July 2025, sent to all US embassies and consulates and reported by The Washington Post, AP and The Guardian, said an impostor posing as Secretary of State Marco Rubio had contacted at least five senior officials, including three foreign ministers and a US governor, by text, Signal and voicemail, with the aim of gaining access to information or accounts. According to AP, two senior officials and the cable described the attempts as using technology driven by artificial intelligence; the Guardian reports that the messages mimicked Rubio's voice and writing style. The department said it was investigating and advised all employees and foreign governments. One official told AP the attempts had been unsuccessful; the technical basis for the AI description was not disclosed.

In an urgent application by Northbound Processing against the South African Diamond and Precious Metals Regulator, Acting Judge DJ Smit of the Gauteng High Court, Johannesburg, found while preparing judgment that two cases cited in the applicant's heads of argument did not exist. According to ITWeb, which saw the court documents, junior counsel first said a wrong version had been filed, a corrected version was found to contain two further incorrect citations, and on the court's direct inquiry junior counsel acknowledged that the citations likely originated from an AI tool called Legal Genius, used under deadline pressure. The judge accepted the legal team's apologies and found no intent to deceive, but referred the conduct of the applicant's legal practitioners to the Legal Practice Council for investigation (June 2025). The applicant obtained the relief it sought.

In the defamation case Coomer v. Lindell in the US District Court for the District of Colorado, a brief that lawyers for Mike Lindell and MyPillow filed on 25 February 2025 contained nearly thirty defective citations, including citations of cases that do not exist. At a conference on 21 April 2025 lead counsel Christopher Kachouroff told Judge Nina Y. Wang that he had drafted the motion and then 'ran it through AI' and had not personally checked the citations. Counsel later said a wrong draft had been filed by mistake; the court was not persuaded. On 7 July 2025 the court found that he and co-counsel Jennifer DeMaster had violated Rule 11 and fined each $3,000 (Kachouroff jointly with his law firm). The court did not sanction Lindell or his companies.

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.

Judicial review grounds lodged in the Upper Tribunal (Immigration and Asylum Chamber) on 26 June 2025 by a solicitors' firm cited four authorities that the judge could not find or that carried wrong citations and propositions. The firm's compliance officer, a solicitor whose name was on the claim form, said a junior fee-earner had drafted the grounds under his supervision; his written explanation named an outdated precedent, practitioner blogs and personal notes as the sources. After a Hamid hearing on 5 November 2025, the tribunal recorded that he accepted the fee-earner had relied on false citations generated by AI, and in a judgment promulgated on 17 November 2025 it referred him to the Solicitors Regulation Authority for the false citations and his failure to supervise. The tribunal said it does not matter how such errors come about. It also announced that the Upper Tribunal judicial review claim form now requires a statement of truth that cited authorities exist and support the propositions they are cited for.

In December 2025 an Assistant U.S. Attorney in the Eastern District of North Carolina filed a response brief for the Department of Defense in a self-represented veteran's lawsuit over health-insurance coverage. The plaintiff identified fabricated quotations and misdescribed case holdings in it. The attorney first attributed the errors to an unfinalized draft filed by mistake. On 2 March 2026 Magistrate Judge Robert T. Numbers II ordered him to show cause why he should not be sanctioned. At the 10 March hearing the attorney, Rudy Renfer, said under oath that he had accidentally overwritten his draft, panicked and used artificial intelligence to draft the brief, and had not verified the cases it cited; he said he had resigned after 17 years in the office, and Courthouse News reported he was terminated the next day. On 28 April 2026 the court issued a public reprimand instead of a fine, writing that his reputation was in tatters and that his job loss already exceeded the usual fines.

The NSW Reconstruction Authority says that between 12 and 15 March 2025 a former temporary staff member (called a former contractor in its first notice) uploaded a Microsoft Excel spreadsheet of Northern Rivers Resilient Homes Program information, 10 columns and more than 12,000 rows, to ChatGPT, an AI platform the Authority had not authorised. The Authority disclosed the breach on 6 October 2025, estimating that up to 3000 people were affected, and later said external forensic analysis confirmed that 2031 people had some of their data uploaded, including names, contact details, addresses, dates of birth, sensitive personal and health information and limited financial commentary. It says no driver licence, Medicare, passport or Tax File Numbers were disclosed and that there is no evidence the data is publicly available or was accessed by a third party; whether OpenAI retained or used the data is not addressed. The Authority apologised, contacted affected people with ID Support NSW, offered to compensate the replacement of compromised identity documents and notified the NSW Privacy Commissioner. A program participant told the ABC the information was deeply personal and that they felt concerned. No misuse of the data is reported.

In a fee dispute between a Louisiana attorney and the City of Aberdeen, Mississippi, briefs filed for both sides in late 2025 cited six cases that do not exist. The attorneys admitted the citations came from unverified AI use: the plaintiff's out-of-state counsel, Kathleen M. Wilson, drafted her filing with an AI drafting program called 'First Drafts', and the City's out-of-state counsel, Kathryn Y. Williams, used an in-house AI legal research tool. Senior Judge Sharion Aycock stayed the case and cancelled the March 2026 trial, then on 8 June 2026 revoked both attorneys' pro hac vice admissions, barred them from the district for two years and fined them $2,500 and $3,500, and disqualified and fined the two local counsel who had signed the filings. Both litigants were left without counsel and given 60 days to find new representation.

On 25 October 2025 the Telugu actor and former Union minister Konidela Chiranjeevi gave Hyderabad cybercrime police a written complaint that several pornographic websites were publishing obscene videos made with AI that morphed his face and likeness, and asked for a criminal and technical investigation and removal of the content, including from mirror sites. Police registered a case under Sections 67 and 67A of the IT Act, several sections of the Bharatiya Nyaya Sanhita and the Indecent Representation of Women (Prohibition) Act. In the complaint he said the videos caused severe and irreparable harm to his reputation and personal and emotional distress to him and his family. He had already obtained an ad-interim injunction from the Hyderabad City Civil Court protecting his name, image and likeness (Gulf News); V6 Velugu reports that he had gone to that court in September 2025 over the same kind of deepfake videos and that on 26 September it ordered their removal. A September 2026 NewsX recap reports that Hyderabad Police Commissioner V C Sajjanar said the cybercrime team was working to trace those responsible.

police, as presented by the Kankan News programme 案件聚焦 (Case Focus), reported in September 2026 that a Shanghai property-engineering contractor had transferred 170,000 yuan in total during a five-month online relationship with a woman he had met on a social platform in 2021. She presented herself as born in 1992, a doctor at a well-known top-tier hospital with hospital property-engineering projects to award, and ran an account with more than 10,000 followers and close to 7,000 short videos of daily life. She refused to meet or take a video call, saying her mother opposed the relationship and demanded a 300,000 yuan bride price and a Shanghai flat; the man reported to a police station when the promised projects never materialised and his savings ran down. Police found she was born in 1961, aged 65, had no medical qualification and had worked as a hospital cleaner; the receiving bank account was registered to another man; the videos were all made with AI skin-smoothing and scene compositing, some carrying a small 'this work contains AI-generated content' label he had never noticed; and she used multiple accounts to play both herself and her long-dead mother. The money had gone on cosmetic treatments and clothing; she had a 2009 fraud conviction with a sentence of four and a half years and is now under criminal coercive measures for suspected fraud. Police also said she kept ambiguous relationships with more than ten people; no other losses are reported.

Santa Fe defense attorney Stephen Aarons used ChatGPT (OpenAI's o3) on a Rev.com transcript and the record to draft briefing in the murder appeal of Oscar Renee Sandoval; the brief contained fabricated witnesses and testimony (including police officers 'Michelle Amarillo' and 'Sanchez' and invented testimony attributed to real people) and misdescribed real precedents. After a 21 August 2026 show-cause hearing at which Aarons admitted he had not verified the output, the New Mexico Supreme Court's written order of 9 September 2026 held him in direct contempt, fined him $5,000 payable to the State Bar Client Protection Fund within 30 days, removed him from the case, barred him from appearing before the court pending a disciplinary-board referral, struck the filed briefs and reassigned the appeal to the public defender.
