1 Dec 2025CzechiaUnidentified legal research tool
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.

On 19 August 2025 a trial court in Andhra Pradesh hearing a suit for an injunction over a property dismissed the defendants' objections to an advocate-commissioner's report on the property, relying on four purported Supreme Court judgments that, according to the defendants and later the courts, do not exist. The defendants challenged the order in the Andhra Pradesh High Court, which, as the Supreme Court recorded, realised the judgments were AI-generated, recorded a word of caution, and on 21 January 2026 dismissed their petition on the merits. On appeal, the Supreme Court said in an order of 27 February 2026 that it took cognisance of the trial court deploying AI-generated non-existing, fake or synthetic alleged judgments, that a decision based on such judgments is not an error in decision making but misconduct, and directed that the trial court not proceed on the basis of the advocate-commissioner's report while the appeal is pending. In May 2026 the Supreme Court asked the Bar Council of India to set up an expert panel on AI-generated fake judgments. The AI tool is not named, the sources read do not name the judge, and no outcome of the appeal had been reported in the sources read.

2025RussiaAntiplagiat AI-text detector
RAPSI and BIZNES Online reported on 8 and 10 June 2026 that the Supreme Court of Tatarstan upheld a ruling that a private Moscow university unlawfully expelled a distance-learning student in 2025 over suspected use of AI in her graduation thesis. According to the university's representatives in court as reported, the Antiplagiat.Vuz system first showed about 41% (41.91%) AI-generated text, her supervisor then said the word order had been deliberately disturbed in more than 70% of the text, and a third check showed 11.92%. BIZNES Online also reports, from the court documents, that a university representative told the court the supervisor does not operate the checking system and had not in fact analysed the text for neural-network generation, and could not explain how the system distinguishes borrowed text from AI generation. The university refused the revised work as late (uploaded on Monday 9 June 2025 against a deadline of 8 June) and expelled her; the department's protocol cited a breach of good-faith work in the Antiplagiat.Vuz system. She denied using AI. In January 2026 the Vakhitovsky District Court of Kazan held the expulsion unlawful, ordered her reinstatement for a check of her thesis and, if it met the originality threshold, admission to the defence, and awarded 40,000 roubles in moral damages and a 20,000-rouble fine. The Supreme Court of Tatarstan dismissed the university's appeal: it held that the probabilistic report had not been checked by a competent expert and could not be the sole proof of bad faith, noted that the same text was classified as AI-generated in one report and not in another, and found no evidence that any flagged fragments resulted from her deliberate acts rather than her sources or an incorrect algorithm. The courts also held the deadline had been miscounted.

26 Jun 2025 to 17 Nov 2025United KingdomUnidentified AI tool
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.

17 Sept 2025 to 21 Sept 2026United KingdomChatGPT
A published Upper Tribunal (Immigration and Asylum Chamber) decision issued on 21 September 2026 records that the grounds of appeal and skeleton argument in a Namibian national's protection appeal were produced by a paralegal at her then solicitors using ChatGPT. The tribunal recorded her counsel's acceptance that the grounds cited fake cases, quoted passages absent from those judgments and attributed to the First-tier judge sentences he never wrote, and itself called one purported quotation pure invention. The September 2025 error-of-law hearing was adjourned, and the appellant later withdrew three of her four original grounds. The tribunal allowed an amended version of her one surviving ground but found that it disclosed no error of law. It refused her permission to add two new grounds, holding that she should not be allowed to advance entirely new grounds, or replace grounds riddled with misrepresentations, so long after the time limit, and in the alternative found those grounds without merit. It directed the Home Office to file any wasted costs application against the firm. The decision states that two individuals have reported themselves to the Solicitors Regulation Authority; the Law Society Gazette reported the decision on 8 October 2026.

May 2025United StatesUnidentified video tool
At a sentencing hearing in May 2025 in Maricopa County Superior Court, Arizona, the family of a man killed in a 2021 road-rage shooting in Chandler played a video that combined real footage with an AI-generated likeness and voice of the victim delivering a script written by his sister, including statements of forgiveness addressed to the defendant. The judge said he loved the video, described it as genuine and referred to the forgiveness it expressed, then imposed the presumptive 10.5-year term for manslaughter, longer than the nine years the prosecutor had requested. The defense attorney appealed immediately. On 30 September 2026 the Arizona Court of Appeals upheld the conviction but vacated the sentence, holding that the AI video was not reliable and that the judge's consideration of it so prejudiced the defendant that the sentencing procedure was fundamentally unfair. The opinion says the record does not show precisely how the video factored into the sentence, and that there is no question it played a role. The case returns to the trial court for resentencing; as of 1 October 2026 no new sentencing date had been set.

Dec 2025CanadaGoogle AI Overviews
In December 2025 Cape Breton fiddler Ashley MacIsaac said a First Nation north of Halifax cancelled his concert planned for 19 December after reading a Google AI-generated search summary that said he had convictions for sexual offences. He says the statements were false and came from online articles about another man in Atlantic Canada with the same last name. The First Nation apologised in writing and Google amended the search results. MacIsaac says he feared for his safety and worries about other lost work. In a statement of claim filed in February 2026 in the Ontario Superior Court of Justice he seeks damages of 1.5 million from Google (US dollars in the Globe and Mail copy of the Canadian Press story, no currency stated in the CBC copy). None of its claims was tested in court. CBC News reported in August 2026 that a notice of discontinuance ending the lawsuit was filed on 29 July 2026; MacIsaac gave no reason, Google did not comment, and no settlement is reported.

2025United StatesUnidentified image tool (suspected)
The Guardian reported on 2 August 2025 that a London-based academic who rented a Manhattan apartment through Airbnb in 2025 was accused by the host of more than 12,000 pounds of damage, supported by photos including a cracked coffee table. She says differences between two photos of the table show they were digitally manipulated or AI-generated. Airbnb first told her to reimburse 5,314 pounds after reviewing the photos, then, five days after Guardian Money asked about the case, accepted her appeal, credited 500 pounds and, after she refused an 854-pound offer, refunded her booking cost of 4,269 pounds, and the host's negative review of her was taken down. Airbnb apologised. Airbnb told the host it could not verify the images he submitted and warned him. The host did not respond to the Guardian. No source establishes that AI was used.

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.

24 May 2025 to 27 Jun 2025Event location unknownGoogle AI Overviews
An author and television producer, the subject of the Apple TV series 'Black Bird', sued Google, alleging that AI Overviews shown for searches about him in May and June 2025 falsely said he was serving a life sentence without parole, in one version for the murders of three women. He says he notified Google three times and received apologies attributing the statements to its AI, yet similar statements kept appearing. On 14 September 2026 the Northern District of Illinois denied Google's motion to dismiss as to two of the four challenged Overviews and dismissed the other two without prejudice. This was a ruling on the pleadings, not a finding that the allegations were proven.
