UB v Secretary of State for the Home Department
Upper Tribunal (Immigration and Asylum Chamber) · Jun 18, 2025
What happened in this matter?
The tribunal found that the appellant's draft Grounds of Appeal contained fabricated and misrepresented case law due to the use of an AI tool. The solicitor admitted the error was inadvertent, caused by filing an uncorrected draft. The tribunal accepted the firm's remedial actions and took no further disciplinary action.
- Why the court cared
- The judge reasoned that while the submission of fabricated and misrepresented authorities was unacceptable and wasted tribunal time, the solicitor's explanation of an inadvertent filing error was credible. The judge further noted the firm's proactive remedial measures, including the implementation of an AI policy and staff training, as sufficient to address the concerns without further sanction.
