“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 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 all “all the circumstances of the case”
