“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”
“If applications for extensions of time are allowed to develop into disputes about the merits of the substantive appeal, they will occupy a great deal of time and lead to the parties’ incurring substantial costs. In most cases the merits of the appeal will have little to do with whether it is appropriate to grant an extension of time. Only in those cases where the court can see without much investigation that the grounds of appeal are either very strong or very weak will the merits have a significant part to play when it comes to balancing the various factors that have to be considered at stage three of the process. In most cases the court should decline to embark on an investigation of the merits and firmly discourage argument directed to them.”
“53 The first stage of the Martland examination can be addressed briefly. Mr Katib’s delay in appealing against the PLNs was, at the very least, 13½ months. That was “serious and significant”
“52. We will approach the third Martland stage by performing, as Martland requires, a balancing exercise. In that balancing exercise, the need for litigation to be conducted efficiently and at proportionate cost and for directions to be complied with must be given particular weight. However, it remains a balancing exercise which invites, among other considerations, a consideration of the nature of the reasons for the breach of direction and the results that would follow if the appeal is, or is not reinstated.”
