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claim form, said a junior fee-earner had drafted the grounds under his supervision; his written explanation named an outdated precedent, practitioner blogs and personal notes as the sources.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.

In the first of two matters decided together in [2026] UKUT 81 (IAC), promulgated on 17 November 2025, the Upper Tribunal (Immigration and Asylum Chamber) examined grounds of appeal dated 17 March 2025 that cited a non-existent Court of Appeal case under the citation of an unrelated equal-pay case. The adviser who drafted them first denied using AI, then told the tribunal his best guess was that he had inadvertently used Google's 'AI Mode', and the tribunal recorded that he had concluded it was probable the case came from inadvertent AI use; the panel itself got Google AI to produce varying benches for the fictitious case. He reported himself to the Immigration Advice Authority and the Solicitors Regulation Authority, and the tribunal said it would otherwise have referred him. He also told the tribunal that he had put client emails and uploaded Home Office decision letters into ChatGPT to summarise them, which he called a data breach he would disclose to the clients; the tribunal said such uploads breach client confidentiality and waive privilege.

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.

From around October 2025, criminals used AI to clone the image, voice, name, signature and firm logo of Ángel Leal, a long-established immigration attorney in Doral, Florida. They created fake videos, look-alike websites, forged contracts and even fabricated Zoom 'immigration hearings' to persuade immigrants to pay for legal services Leal never provided. Immigrants were defrauded of money, and some believed their cases were progressing when they were not; Leal received one to two defrauded callers a day, changed his phone number, hired an anti-piracy firm that removed thousands of fake profiles and videos, and reported the fraud to local police and federal authorities.
