“9. Mr Black referred me to the often-cited extract from the judgment of Lightman J in Mobile Export 365 Limited anor v Revenue and Customs Commissioners[2007] 15 STC 1794 . In giving guidance to the Tribunal in that case, Mr Justice Lightman said (at [20]): “The presumption must be that all relevant evidence should be admitted unless there is a compelling reason to the contrary.” 10. Accordingly, I should first decide if the evidence of Mr Henderson is relevant. If I decide that it is, and should therefore in an ordinary case be admitted, I need then to go on to determine if there is a compelling reason why it should not……….. 17. In Revenue and Customs Commissioners v Brayfal Limited CH/2008/APP0082 (unreported), Lewison J referred to Commissioners of Customs and Excise v Neways International (UK) Limited[2003] STC 795 and to the requirement set out by Lloyd J in that case that in considering whether to extend time or otherwise deal with a default, the Tribunal should conduct a balancing exercise, weighing the consequences of the default for the innocent party against the possible consequences of any sanction for the party in default. That balancing exercise was held to be equally appropriate in Brayfal in a case where there was an application to admit additional documents.”
“44. The new evidence may be prejudicial to the appellant’s case. They do not want it in. But that is not the issue. The issue is whether there is procedural prejudice: will the appellant be handicapped by the allegation being made now rather than when it should have been made in the Statement of Case? I have determined that I cannot see, for the reasons given above, any significant procedural prejudicial to the appellant for the allegation to be made, and the evidence to be admitted, now. And as I have also determined that the evidence and allegation may potentially be of real help to the Tribunal in reaching its conclusions, and that HMRC’s delay by itself is not a reason to refuse to admit it, my decision on balance is to admit it.”
“44. When the FTT is considering applications for permission to appeal out of time, therefore, it must be remembered that the starting point is that permission should not be granted unless the FTT is satisfied on balance that it should be. In considering that question, we consider the FTT can usefully follow the three-stage process set out in Denton : (1) Establish the length of the delay. If it was very short (which would, in the absence of unusual circumstances, equate to the breach being “neither serious nor significant”), then the FTT “is unlikely to need to spend much time on the second and third stages” - though this should not be taken to mean that applications can be granted for very short delays without even moving on to a consideration of those stages. (2) The reason (or reasons) why the default occurred should be established. (3) The FTT can then move onto its evaluation of “all the circumstances of the case”
