High Court refers a solicitor to his regulator after fictitious citations from research his client says was AI-generated were put before the court
A Divisional Court judgment of 6 June 2025 ([2025] EWHC 1383 (Admin)) records that, in a commercial claim against a Qatari bank, correspondence and witness statements filed by the claimant and his solicitor relied on numerous authorities that a judicial assistant's schedule found to be fictitious or misquoted: 45 citations, 18 of which referred to cases that do not exist. The claimant's witness statement says the citations were generated using publicly available artificial intelligence tools, legal search engines and online sources. The solicitor's statement says he relied on the client's research without verifying it, that he had reported himself to the Solicitors Regulation Authority and that he had removed himself from all litigated matters. The court found a lamentable failure to check the material, accepted that the solicitor did not realise the citations were false, held that the threshold for contempt proceedings was not met, and said it would also refer him to the regulator. The judgment does not record any later disciplinary outcome.

What Happened
The filings. The claimant sought damages of about £89.4 million for alleged breaches of a financing agreement against Qatar National Bank and QNB Capital. After Dias J extended the defendants' time to file evidence in April 2025, the claimant applied to set that order aside, relying on his own witness statement and one from his solicitor. On 9 May 2025 Dias J dismissed the application and referred the papers to the Hamid judge, recording that correspondence with the court and both witness statements relied on numerous authorities which appeared to be either completely fictitious or, if they existed, did not contain the passages quoted or did not support the propositions cited. The judicial assistant's schedule listed 45 citations; in 18 instances the case cited did not exist, and many of the real cases were misquoted or irrelevant.
The AI research. In his witness statement the claimant accepted responsibility for the inaccurate and fictitious material and said the citations had been generated using publicly available artificial intelligence tools, legal search engines and online sources. He said he had complete, though misplaced, confidence in the authenticity of the material and did not intend to mislead; he sought to absolve his solicitor. No tool is named, and no query, output or date of the research is recorded.
The solicitor. The solicitor's statement accepted that his own witness statement cited non-existent authorities and said he had relied on the client's legal research without independently verifying it. He said he had never previously been reported to the Solicitors Regulation Authority, had reported himself, had removed himself from all litigated matters and would undertake training. His counsel accepted that the conduct could not be worse and that the last thing a solicitor should do is rely on a lay client's research, pointing in mitigation to the self-referral and to the fact that a barrister who had seen the documents had not flagged the fake citations.
The court's conclusions. The Divisional Court (the President of the King's Bench Division and Johnson J) accepted that the claimant had no intention to mislead but said its focus was on the lawyers: it was extraordinary that the lawyer was relying on the client for the accuracy of legal research rather than the other way round. It found a lamentable failure by the solicitor and his firm to check the accuracy of material put before the court, was satisfied that he did not realise the true position, held that the threshold for contempt proceedings was not met, noted his self-referral and said it would also make a referral to the Solicitors Regulation Authority. It did not refer the barrister to the Bar Standards Board. In its wider remarks the court said these Hamid cases showed that regulatory guidance on its own was insufficient to address the misuse of artificial intelligence, and sent the judgment to the Bar Council, the Law Society and the Council of the Inns of Court.
Limits. The judgment is the only inspected source. The consequences recorded are the solicitor's own withdrawal from litigated matters and the court's referral; whether the regulator later imposed any sanction is not established. The claimant's application was dismissed on 9 May 2025, but the judgment does not attribute that dismissal to the fake citations.
Reported harm
The solicitor’s own statement records his withdrawal from all litigated matters and his self-referral to the Solicitors Regulation Authority, and the court said it would also refer him. No disciplinary penalty is recorded.
How Harm Occurred
A litigant's legal research, which he says was generated with publicly available AI tools, legal search engines and online sources, produced citations of cases that do not exist and quotations that real cases do not contain. His solicitor adopted that research in correspondence and a witness statement without checking it. The court's response to the solicitor's failure to verify (a referral to the Solicitors Regulation Authority) and the solicitor's own withdrawal from litigated matters are the recorded professional consequences.
Outcome
UnknownThe solicitor reported himself to the Solicitors Regulation Authority before the hearing of 23 May 2025, and the court said in its judgment of 6 June 2025 that it would also make a referral. The court declined to initiate contempt proceedings. The judgment does not record any regulatory outcome, and none was researched for this review.
What remains unknown
- Which AI tools, search engines or online sources produced the citations, what was asked of them, what they returned and when; the claimant’s statement names none and the court did not examine them.
- Where the research was done and where the solicitor practises; the judgment does not say, so event and affected-person countries are left empty.
- The dates of the correspondence and witness statements that contained the citations, beyond their falling between the April 2025 order and the 9 May 2025 dismissal.
- Any outcome of the self-referral or the court’s referral to the Solicitors Regulation Authority; nothing after 6 June 2025 was researched.
- Whether the dismissal of the claimant’s application on 9 May 2025 or the underlying claim was affected by the citations; the judgment does not say.
What the evidence supports
AI involvement: supported. The claimant's witness statement, as recorded in paragraph 76 of the judgment, says the citations put before the court were generated using publicly available artificial intelligence tools, legal search engines and online sources, and the court treated these Hamid cases as instances of the misuse of artificial intelligence (paragraph 82). The AI output reached the harmed solicitor only through his client's research; no source describes any output, decision or claim by an AI system about the solicitor himself. The harm recorded here is the court's and the solicitor's own response to unverified AI-generated material having been filed, which is a consequential-response case under the charter, so the person relation is recorded as unknown with the consequential_response exemption. No tool, query or output is identified.
4 claims: 2 documented, 2 reported. What the statuses mean
Documented Dias J's reasons of 9 May 2025, quoted in the judgment, record that correspondence with the court and the witness statements of the claimant and his solicitor relied on numerous authorities that appeared either completely fictitious or not to contain the passages quoted, and the judicial assistant's schedule lists 45 citations of which 18 referred to cases that do not exist.
Causal attribution. Directly established by the court record (paragraphs 73 and 74). The count of citations is the schedule prepared by a judicial assistant as recorded by the court.
- judiciary.uk(opens in new tab) supports · English
'reliance is placed on numerous authorities, many of which appear to be either completely fictitious or which, if they exist at all, do not contain the passages supposedly quoted from them'; 'lists forty five citations that had been put before the court. In eighteen instances, the case cited does not exist.'
Reported The claimant's witness statement, as recorded by the court, says the citations were generated using publicly available artificial intelligence tools, legal search engines and online sources, that he had misplaced confidence in their authenticity and that he did not intend to mislead.
Causal attribution. The AI origin of the citations rests on the claimant's own statement, which the court records and does not contradict; no tool, prompt or output was inspected by the court or this review.
- judiciary.uk(opens in new tab) supports · English
'He says that the citations were generated using publicly available artificial intelligence tools, legal search engines and online sources. He had complete (but he accepts misplaced) confidence in the authenticity of the material that he put before the court.'
Reported The solicitor's witness statement, as recorded by the court, says he relied on the client's legal research without independently verifying the authorities, that he had reported himself to the Solicitors Regulation Authority and that he had removed himself from all litigated matters.
Causal attribution. The solicitor's own account of his reliance and of his withdrawal, recorded by the court. The withdrawal is his own response; no employer or regulator decision is recorded.
- judiciary.uk(opens in new tab) supports · English
'He says that he relied on legal research that Mr Al-Haroun had conducted, without independently verifying the authorities. He accepts this was wrong.'; 'He has reported himself, and he will send them a copy of his witness statement.'; 'he has removed himself “from all litigated matters”'
Documented The Divisional Court found a lamentable failure by the solicitor and his firm to check the accuracy of material put before the court, was satisfied that he did not realise the true position, held that the threshold for contempt proceedings was not met, and said it would also refer him to the Solicitors Regulation Authority.
Causal attribution. The findings and the referral are the court’s own decisions in paragraph 81. The court connects them to the failure to verify the client’s research; it does not attribute the dismissal of the underlying application to the citations.
- judiciary.uk(opens in new tab) supports · English
'there was a lamentable failure to comply with the basic requirement to check the accuracy of material that is put before the court.'; 'The threshold for the initiation of contempt proceedings is, accordingly, not met.'; 'has referred himself to the Solicitors Regulation Authority.

Reviewed for publication 2026-10-07: Published as a consequential-response case on the inspected approved judgment: the court records that the claimant said the citations were generated with publicly available AI tools, that the solicitor adopted them without checking, and that the court found a lamentable failure, declined contempt proceedings and said it would refer him to the regulator; the solicitor's own withdrawal from litigated matters and self-referral are recorded from his statement. The person relation is unknown because no source describes an output or action by an AI system toward the solicitor; the harm is the court's and the solicitor's own response to unverified AI-generated material having been filed. The solicitor and his firm are named in the public judgment but not in this record's narrative. No later disciplinary outcome is claimed.

Puerto Rico federal judge sanctions a soccer league's lawyers over 55 defective citations he said bore hallmarks of generative AI; the lawyers deny using AI
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.
Paraná labour court annuls expert report carrying a hidden instruction aimed at AI and fines the court-appointed expert, report says
A labour court in Castro, Paraná (9th Region Labour Court), annulled a court-appointed expert's report after the employer, in a motion for clarification, reported a hidden sentence at the foot of a page instructing artificial intelligence to contest the report only superficially and not to question the files it cited, according to Diário de Justiça. The expert confirmed the text but said it came from teaching material about AI and was inserted by accident; the court's IT section concluded that it had been formatted deliberately to be invisible. The judge said AI had not been used to write the judgment and that the text did not directly influence it, but annulled the report, later submissions and the judgment, ordered a new examination by another expert without AI tools, fined the expert 5% of the value of the case for bad-faith litigation, cancelled the expert's fees and removed the expert from the court's register. The decision, dated 12 October 2026, can be challenged.
Massachusetts: fired teacher asks court to vacate an arbitration, saying the arbitrator improperly used AI tools to judge her AI-detector evidence
A kindergarten teacher at a public elementary school in Concord, Massachusetts, was dismissed in August 2025 after an unsatisfactory evaluation. In arbitration she argued that some of the principal's evaluations may have been produced with AI, relying on GPTZero estimates; the principal denied using AI beyond grammar checks. According to the arbitration decision as reported by The Concord Bridge, the arbitrator stated in an appendix that he used two AI tools, GPT-5.4 and Claude Opus 5, to research whether GPTZero was reliable, checked some of the sources they supplied, concluded that GPTZero's results deserved no weight, and upheld the dismissal on 27 August 2026. On 28 September 2026 the teacher asked Suffolk Superior Court to vacate the decision, alleging that the AI-assisted research was an improper investigation outside the hearing record that the parties were not told about or allowed to challenge. These are allegations in a complaint; the district declined to comment and no court has ruled.
Jeju: police refer a middle-school student over secretly filming teachers and making sexual deepfake composites; teachers dispute victim count and legal aid
Jeju Dongbu police announced on 23 September 2026 that a student at a middle school on Jeju had been referred to prosecutors without detention on 17 September for violating the Sexual Violence Punishment Act (filming with a camera or similar device). The student's phone was voluntarily submitted by his guardians and forensically examined; the examination found footage relating to some teachers and some sexual composites, and the student admitted the conduct. News1 reported that the student was booked for filming a teacher's body with his phone during a school field trip around mid-July 2026, that the offending had continued for several months with multiple victims, and that police found no indication the composites had been distributed. Police told Seoul Shinmun there were more victim teachers than the one first reported but withheld the number to avoid secondary harm, and that no student at the school was a victim; the Jeju teachers' union questioned whether the full scope of harm had been established. According to the union, two months on the victim teachers were receiving hospital treatment and counselling while teaching daily, gave police statements on 14 September without a lawyer, attended the regional teachers' rights protection committee on 17 September without institutional support, wrote the criminal complaint themselves, and were offered 3.3 million won in legal fees for all of them together, payable after the case ends; two requests to meet the superintendent were not accepted. On 29 September one of the victim teachers gave a press interview at the Jeju Teachers' Union office. She said that early in the investigation she had seen on the student's phone material showing other teachers and current students, had made a list of the people and types of harm, and that the material shown to her at the police victim examination was considerably less than what she had seen; Yonhap-chain outlets quote her as saying the students she recognised numbered 10 to 20 and that a graduate had suffered worse deepfakes. She said investigators asked the school only to identify the perpetrator and never requested material to identify the students in the footage, and that the school sent parents a letter premised on there being no student victims. Police replied that phone forensics had been thorough, that every act beyond social norms had been identified and proven, and that one student victim had been confirmed, a student at a different school. The teachers were notified on 22 September that the case had gone to the prosecution and on 24 September that it had been sent to the court's juvenile division as a juvenile protection case, before they had submitted further evidence and a victim opinion. The teacher said the original complaint had also asked police to examine whether physical contact in 2025 was forcible molestation and whether repeated approaching and waiting in 2026 was stalking, and Halla Ilbo reports that such conduct is said to date from 2025. Yonhap-chain reports describe the charged victims as five teachers. The same day the education office briefed on legal-aid rules (up to 6.6 million won per instance when a teacher is sued, 3.3 million won per case when a teacher files a complaint; office lawyers cannot act as a teacher's private counsel), said it had linked the teachers to the national Digital Sexual Crime Victim Support Center, announced an integrated support system through a hotline, and its section head said the office was sorry that early support had not been felt. The KTU Jeju branch (28 September) and the Jeju Teachers' Union (14 and 29 September) demand a victim-support system, per-teacher legal fees paid in advance and a dedicated support team. On 6 October 2026 Seogwipo Broadcasting reported, citing people in education and a tipster, that the education authority had finally rejected the victim teachers' application for lawyer fees for an additional criminal complaint, saying in a written opinion that with a police investigation already under way a further complaint could hardly stop or prevent the infringement of their teaching, so the support requirements were not met; critics contrast this with full legal-cost support in earlier sexual-offence cases.
