Jun 2025Event location unknownLegal Genius (reported)
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.

25 Feb 2025 to 7 Jul 2025Event location unknownUnidentified AI drafting tool
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.

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.

2025IndonesiaUnidentified image and video tool
Indonesian businessman Mohamad Jusuf Hamka reported to Jakarta police on 18 October 2025 that videos circulating on TikTok showed him and his daughter as if wearing prosecutors' detainee uniforms, tied to narratives of corruption, bribery and gratification over the Cawang-Pluit toll concession, which he denies and his lawyers call false; his lawyers say the faces were composited into staged scenes with AI, and that other content called him a 'toll mafia' and posted a fabricated poster of him running for president in 2029. Polda Metro Jaya's cyber directorate arrested the holder of the TikTok accounts on 27 November 2025; Hamka and his lawyers say the defendant admitted to police that he made the content on others' instructions for Rp500,000 per item; tvOneNews and TVRI note this is Hamka's side's claim within the contested case, and Poskota reports it is being examined at trial. The case file was reported complete (P21) on 12 August 2026 and the trial opened at the Central Jakarta District Court on 15 September 2026 under the Electronic Information and Transactions Law (Article 35 jo 51(1), maximum 12 years) and alternative counts. Hamka told reporters the content disturbed him and could damage his reputation and that the campaign was systematic. At the 29 September 2026 hearing the judges asked about restorative justice; Hamka's lawyer said there was no room for it unless the defendant named who ordered and paid for the content. The defendant's lawyer said the content related to his work as secretary-general of an anti-corruption committee and that the indictment was unclear.

Apr 2025Event location unknownGoogle AI Overviews
Italian outlets report that Google's AI Overview feature told searchers that Claudio Zorzi, head of orthopedics and traumatology at the IRCCS Sacro Cuore Don Calabria hospital in Negrar (Verona), had died. According to the hospital, the surgeon is alive and operating, and the error probably came from confusion with a general practitioner of the same name who died. The false news is reported to have circulated since April 2025 and to have recurred. Zorzi said he felt uncomfortable because people who think he is dead do not look for him, and he reported the notice to the postal police. On 15 October 2025 the hospital served Google, through its lawyers, with a formal cease-and-desist and default notice and reserved a damages claim. No Google response was found. The AI Overview output itself was not inspected.

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.
