Omar Rafique v The Commissioners for His Majesty's Revenue and Customs
UKFTT (Tax Chamber) · May 6, 2026
What happened in this matter?
The Tribunal issued a formal warning to the pro se appellant regarding the use of AI-generated fabricated authorities. While the Tribunal found the conduct constituted a serious breach of the duty not to mislead the court, it declined to initiate contempt proceedings, instead providing the appellant with explicit notice of his ongoing obligation to verify the veracity of all cited legal authorities.
- Why the court cared
- The Tribunal reasoned that while the appellant had a duty not to mislead the court, there was insufficient evidence that he was aware of the concept of AI hallucinations or the potential for contempt of court. The judge emphasized that litigants in person are not immune from sanctions for serious procedural breaches, but concluded that a warning was appropriate given the appellant's likely lack of intent.
- Why it matters now
- This case illustrates the Tribunal's approach to pro se litigants who inadvertently introduce AI-hallucinated law. It establishes that while tribunals may grant latitude to unrepresented parties, they will explicitly warn against the duty to verify AI-generated submissions and clarify that such conduct can constitute contempt of court.
Why this matter is tracked
In a tax appeal before the UK First-tier Tribunal, a pro se appellant submitted multiple emails containing AI-generated legal arguments and fabricated case law. The Tribunal found that the appellant relied on hallucinated authorities, including non-existent cases and misapplied precedents, to support his position on Stamp Duty Land Tax and VAT liabilities. Although the Tribunal determined the appellant's conduct constituted a serious breach of the duty not to mislead the court, it declined to refer the matter for a contempt of court summons, noting the appellant likely lacked prior awareness of AI hallucination risks. The Tribunal ultimately refused the appellant's application for reinstatement of his appeal, which had been struck out for failure to comply with procedural directions.
