“26. Jones is clear authority for the proposition that the First-tier tribunal has no jurisdiction to go behind the deeming provisions of paragraph 5, Schedule 3. If goods are condemned to be forfeited, whether in fact or as the result of the statutory deeming, it follows that, having been bought in a Member State and then imported…, they were not held by the taxpayers for their own personal use in a way that exempted the goods from duty. The reasoning and analysis in Jones did not turn on the fact that the case concerned restoration of the goods and not assessment to duty. … 33. … It is clearly not open to the tribunal to go behind the deeming effect of paragraph 5 Schedule 3 for the reasons explained in Jones… The fact that the appeal is against an assessment to excise duty rather than an appeal against non-restoration makes no difference because the substantive issue raised by Mr Race [that the goods were in fact for own use] is no different from that raised by Mr and Mrs Jones. … 39…the First-tier Tribunal could no more re-determine, in the appeal against the Penalty Assessment, a factual issue which was a necessary consequence of the statutory deeming provision than it could re-determine a factual issue decided by a court in condemnation proceedings. The issue of import for personal use…has been determined by the statutory deeming.” 39. In HMRC v Susan Jacobson[2018] UKUT 18 TCC , the Upper Tribunal stated at [24]: “We respectfully agree with Warren J in Race that the reasoning and analysis in Jones applies to an appeal against a penalty in exactly the same way as it applies to an appeal against an assessment for excise duty. The deemed effect of Ms Jacobson’s failure to contest the seizure of the HRT was that it was duly condemned as forfeited as, in the terms of regulation 88 of the 2010 regulations, goods liable to excise duty which had not been paid in contravention of the Regulations.”
