UK and R (Munir) v Secretary of State for the Home Department
Upper Tribunal · Nov 17, 2025
What happened in this matter?
The Upper Tribunal referred a solicitor to the Solicitors Regulation Authority (SRA) for professional misconduct after he submitted judicial review grounds containing multiple fabricated and misrepresented case citations. The Tribunal held that the solicitor, as the supervisor, was responsible for the accuracy of work produced by his junior staff and failed to prevent the submission of false legal authorities.
- Why the court cared
- Fabricated: Case Law | A non-existent case 'Horleston' was included in the grounds; the Tribunal found no reported case and demonstrated that Google AI can fabricate bench details—solicitor concluded it was probably AI-generated. || Misrepresented: Case Law | R (Dzineku-Liggison) v SSHD was cited with a High Court citation that does not exist; the correct authority is an Upper Tribunal decision. || Misrepresented: Case Law | A decision labelled 'Patel (mandatory refusal – fairness)' was cited as a Court of Appeal decision though the correct report is an Upper Tribunal decision. || Misrepresented: Case Law | Muhandiramge was cited with an Administrative Court citation that the Panel could not locate; the relevant reported decision is an Upper Tribunal decision with a different date and citation. || Misrepresented: Case Law | A case referred to as OE (Nigeria) with citation [2010] UKUT 35 (IAC) could not be found; the matter appears to correspond to a differently titled Upper Tribunal decision.

Why this matter is tracked
The Upper Tribunal addressed two separate instances of legal representatives submitting false case citations in immigration proceedings. In the first matter, a solicitor admitted to including a non-existent case, likely generated by Google AI, in grounds of appeal. In the second, a solicitor and his supervisor submitted grounds for judicial review containing multiple misrepresented or non-existent authorities, attributed to a junior caseworker's reliance on outdated precedents and lack of supervision. The Tribunal emphasized that legal professionals are strictly responsible for the accuracy of all cited authorities, regardless of whether errors arise from AI hallucinations or poor supervision. The Tribunal referred the second solicitor to the Solicitors Regulation Authority (SRA) for professional misconduct, noting that supervisory failures are particularly culpable.
