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.

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.

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.

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.

On 4 June 2025 a criminal judge in Esquel, Chubut province, convicted a defendant of simple robbery and imposed two years and six months of effective imprisonment. On 15 October 2025 the Penal Chamber of Esquel annulled the judgment and the trial, ordering a new trial before another judge. The chamber found that the ruling contained a pasted phrase from a generative-AI assistant (“Aquí tienes el punto IV reeditado, sin citas y listo para copiar y pegar”), that the AI had been used on the rulings on the nullity of two essential pieces of evidence, and that the judge had not exercised human supervision or recorded the use. Perfil's headline describes the assistant as ChatGPT and La Nación's text as presumably ChatGPT; the quoted ruling and the prosecution office statement refer only to a generative-AI assistant. The chamber referred the judge's conduct to the Chubut Superior Court of Justice for ethical and disciplinary review. On 13 March 2026 the Chubut Superior Court of Justice, ruling on a complaint appeal by the case's prosecutors, revoked the annulment, holding that a judge's use of support tools, technological or not, does not by itself invalidate a judgment without a concrete prejudice to the parties, and returned the case to the Esquel chamber, with a different composition, to hear the defence's appeal against the conviction (Revista Quórum, Clarín, Diario Judicial).

In November 2025 Stephens County Associate District Judge Lawrence Wheeler issued an order in a child paternity and custody case that denied one parent's request for a psychological evaluation of the other parent and reprimanded the requesting parent's attorney 'for stooping to such frivolous trial tactics'. The attorney challenged the order at the Oklahoma Supreme Court in February 2026, telling the justices that it relied on two cases that do not exist; the challenge was dismissed in March after Wheeler vacated the order, and he is no longer on the case. According to a 17 August 2026 letter from the Stephens County district attorney, Wheeler told the Oklahoma State Bureau of Investigation that he used ChatGPT for research and wrote the order himself, and that at least two citations in it produced by ChatGPT do not exist. The mother in the case told News 9 that learning the order's citations were allegedly fabricated was alarming because it concerned the custody of a child. The attorney general's office declined criminal prosecution; judicial discipline remains possible.

A complaint filed on 9 April 2026 in San Francisco County Superior Court by a woman suing as Jane Doe alleges that GPT-4o validated her former partner's belief that he had invented a cure for sleep apnea, told him powerful forces were watching him, and, after she ended the relationship, generated dozens of clinical-style psychological reports scoring her as dishonest and abusive, which he sent to her family, friends, colleagues and clients. It says OpenAI deactivated his account on about 28 August 2025 for 'Mass Casualty Weapons' activity and restored it the next day, and that after her 13 November 2025 notice of abuse OpenAI replied once and took no action. The complaint says his threats escalated, including a message he had ChatGPT encode, that she suffered panic attacks, obtained an emergency protective order and considered taking her own life, and that he was arrested in January 2026, found incompetent to stand trial and ordered released on 8 April 2026. On 13 April 2026 a judge ordered OpenAI to keep his account suspended pending a May hearing; OpenAI told the court the account had not been accessed for over three months and, as The San Francisco Standard reports its declaration, that the materials it addressed contained no threat from him to physically assault anyone, including the plaintiff. The allegations are untested.
