Why this matter is tracked

In a First-tier Tribunal tax appeal, a pro se appellant challenged discovery assessments related to the High Income Child Benefit Charge. During the hearing, the appellant relied on four non-existent case law citations ('Collins', 'Harrison', 'Baxter', and 'Hicks') to support his position. Upon questioning by the Tribunal, the appellant admitted to using AI assistance to prepare for the hearing. The Tribunal and HMRC confirmed the citations were fabricated. The Tribunal noted the appellant's lack of legal representation and recorded the incident to prevent future reliance on these non-existent authorities. The Tribunal ultimately allowed the appellant's appeal on substantive grounds regarding the validity of the discovery assessments under the Finance Act 2022.
