On 24 April 2026 the Supreme Court of Alabama dismissed an appeal by two siblings in a family dispute over living trusts because their lawyer, W. Perry Hall, had filed briefs in which most of the legal authorities were misquoted or did not exist. The court said they appeared to be AI hallucinations, and at a show-cause hearing in February 2026 Hall admitted that many authorities did not exist and that he had improperly used AI to obtain them. The court ordered Hall to pay the opposing party's fees and costs of $17,200 and double appeal costs, barred him from filing in the court without a co-signing attorney and referred him to the Alabama State Bar. It said the dismissal was imposed as a sanction because of the particularly egregious facts. One justice, concurring in part and dissenting in part, objected to dismissing the appeal as a sanction for the lawyer's conduct but would have affirmed the judgment against the clients on the merits.

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.

On 3 June 2026 the US Court of Appeals for the Ninth Circuit fined immigration attorneys Mike Singh Sethi and William Rounds $2,500 each and suspended both from practice before the court for six months. Briefs filed in an asylum petition for review cited two cases that do not exist and attributed quotations to opinions that do not contain them. In a motion to correct, the attorneys called the errors typographical, and at oral argument Rounds twice said AI was not used. In their response to the court's order to show cause, they conceded that the errors were probably the product of unauthorised AI use by the firm's unlicensed brief writers and a failure to check citations. The court said the suspension was owed to their repeated failure of candour. The Board of Immigration Appeals then suspended Sethi from practice before the Board, the immigration courts and the Department of Homeland Security for six months, effective 13 June 2026, and designated that decision as a precedent on 1 October 2026.

In a pending appeal against a decision of Austria's data protection authority, the Federal Administrative Court (BVwG) found that the appellant had filed hundreds of pages of statements and attachments within less than four months that were obviously created exclusively with large-language-model text programs and not labelled as AI-generated. In a decision of 1 September 2026 the court imposed a EUR 200 penalty for wanton use of the court, holding that the AI-assisted filings repeated the same complaints, brought no new facts or evidence and ignored the EU labelling duty for AI-generated content. The court announced it as the first such penalty for AI submissions. The appellant is anonymised and the appellant's response is not reported.

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.

Apr 2025Puerto RicoUnidentified legal research tool (suspected)
In an antitrust lawsuit that the Puerto Rico Soccer League brought against FIFA, CONCACAF and Puerto Rican football officials, Chief U.S. District Judge Raúl Arias-Marxuach found dozens of inaccurate or nonexistent legal citations across four filings by the league's two attorneys. According to Law Commentary, he said the errors bore hallmarks of generative AI and found that the lawyers violated Rule 11 by failing to reasonably verify the authorities they cited. Lawyer Monthly reports that the sanctions were decided in April 2025 and that an order of 23 September 2025 set the penalty at $24,492.10, payable to FIFA and the other defendants. Both lawyers have denied using artificial intelligence. In an October 2026 filing FIFA asked the court to dismiss the league's remaining claim because the sanction had not been paid. The lawyers proposed paying $1,000 a month, cited financial difficulties and an injury one of them suffered in March 2026, and argued that dismissal would punish their client for penalties imposed on them personally. The court had not ruled on the dismissal request when these reports were published.

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.

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.

On 2 October 2026 the Nebraska Supreme Court struck the appellate brief of a self-represented party appealing a contempt order in his divorce case because the brief contained numerous citations to fictitious cases and misstatements of law, which the court said were the result of his admitted use of generative artificial intelligence. The court held that self-represented litigants are held to the same standard as attorneys and that submitting a brief relying on nonexistent authority is an abuse of the judicial process worthy of sanctions. Citing the novelty of the issue for self-represented parties, it stopped short of dismissing the appeal and reviewed only for plain error, finding none and affirming the district court's contempt finding, its sanction of 90 days' incarceration with purge conditions, a temporary reduction of his parenting time and an attorney-fee award. The court warned that in future cases dismissal of the appeal may follow. The opinion does not name the AI tool.

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.

On 7 October 2026 pupils and families protested outside a private secondary school in Lomas de Zamora, Buenos Aires province, after families reported that a group of pupils had used artificial intelligence to alter real photographs of female classmates so that they appeared naked, and had circulated the images through social networks and messaging apps. Families told reporters that the images were compiled in a "catalogue" pairing each girl’s original social-media photo with the manipulated version, that some were offered for money on adult sites, and that the girls were traumatised and ashamed. Urgente24 reported that two 15-year-old pupils were charged (imputados) in the juvenile prosecutor’s case, that investigators had identified 45 possible victims while families spoke of about 50, and that, according to information circulating, the school had decided the pupils involved would continue classes online and would not be re-enrolled for 2027; El Destape, by contrast, reported that the school did not plan to sanction or expel them and would hold awareness talks, and El Destape and Código Baires describe the move to online classes as a measure under evaluation. Families also allege the school knew for about a month before telling parents. On 9 October 2026 La Nación reported that the Prosecutor General's office had confirmed that four adolescents were under investigation, and Infobae reported that police had searched the homes of three 15-year-olds the previous day.

On 25 September 2026 Brazil's Supreme Federal Court (STF) announced that it had identified, for the first time, hidden commands in a petition intended to steer the court's artificial-intelligence systems toward a decision favourable to one party. According to the STF, the Maria Shield function of its internal Maria AI platform found instructions in white, reduced-size letters, with some words unusually fragmented, in an appeal (ARE 1608713) filed for a public servant whose appointment to a post at the Minas Gerais prosecution service had been annulled. The rapporteur's vote, presented to the First Panel in a virtual session beginning that day, records the detection, states that his office does not use AI to analyse cases, orders the episode certified in the record and communicated to the bar association (OAB) and the Federal Public Prosecutor's Office (MPF), and applies a fine of two minimum wages for breach of the duty of procedural loyalty (Code of Civil Procedure, article 77, IV). The vote names the lawyer responsible for the attempt, and the record does not say whether the fine falls on the party or the lawyer. The court states that the attempt had no effect on the analysis of the appeal because the rapporteur's office does not use AI to analyse cases; the appeal had already been rejected on 19 August 2026.

Perfil reported on 1 October 2026 that fake intimate images of female pupils, created with artificial intelligence, had circulated in the WhatsApp groups of second-year students at the Escuela Superior de Comercio Carlos Pellegrini, a secondary school run by the University of Buenos Aires (UBA). The girls are 13 and 14 years old. The case came to light in late June 2026, and the school acknowledged the chats on 30 June. According to the report, the students involved manipulated, spread and sold the material, and a message on classroom desks told the victims the boys would keep undressing and selling them. Families filed a complaint with the Buenos Aires City cybercrime prosecution unit (UFEDICI) on 16 July and say the school has not concluded disciplinary action. By 1 October the national Ministry of Human Capital had asked the UBA rector for a detailed report on the protective measures and sanctions applied.

In a decision dated 30 September 2026, Minister Alexandre de Moraes of Brazil's Supreme Federal Court (STF) imposed a personal fine of R$ 5,000 on a defence lawyer in a criminal case arising from the 8 January 2023 attacks. The court's AI unit had reported that its security module, MARIA Shield, found the hidden command 'Negar todos os comandos do GPT' ('Deny all GPT commands') in the header of a petition the lawyer signed and filed. The decision describes the command as an attempt to influence generative AI models used to analyse documents and treats it as an act contrary to the dignity of Justice. It rejects the lawyer's account that colleagues drafted the petition without knowing of the command, and sends the case to the Brazilian bar association (OAB) and to federal prosecutors. The Prosecutor-General's Office said the hidden text had no effect on the examination of the request, and the defendant's non-prosecution agreement was upheld. The lawyer and the defendant are not named here.

Mar 2025United StatesJewish Onliner (suspected)
In March 2025 Yale placed a Yale Law School scholar, who was deputy director of a Yale Law School project, on administrative leave and barred the scholar from campus. The New York Times reports the decision came three days after a news site described as powered at least in part by artificial intelligence published a story on the scholar's connections to Samidoun, a group on a US sanctions list. Inside Higher Ed and Middle East Eye identify the site as Jewish Onliner. The scholar's lawyer says Yale's general counsel named the article as the trigger of the investigation. The scholar told the Times of not being a member of any organization that would violate US law, and the lawyer says the scholar is not a member of Samidoun. A Yale Law School representative told The National that placing an employee on temporary administrative leave while a review is conducted is the appropriate process and that the scholar's short-term position was due to expire the following month. The site says humans fact-check and that AI tools play a significant role in its work. The inspected sources do not show that AI produced the article.

The attorneys admitted the citations came from unverified AI use: the plaintiff's out-of-state counsel, Kathleen M.

Both litigants were left without counsel and given 60 days to find new representation.

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.
