“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: (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”
“which will assess the need to conduct all litigation efficiently and at proportionate cost and for statutory time limits to be respected. The FTT's role is to exercise judicial discretion taking account of all relevant factors, not to follow a checklist.” “In doing so the FTT can have regard to any obvious strengths or weaknesses of the applicant’s case: this goes to the question of prejudice- there is obviously a much greater prejudice for an applicant to lose the opportunity of putting forward a really strong case than a very weak one. It is important that this does not descend into a detailed analysis of the underlying merits of the appeal.”
