“[34] … Applications for extensions of time limits of various kinds are commonplace and the approach to be adopted is well established. As a general rule, when a court or tribunal is asked to extend a relevant time limit, the court or tribunal asks itself the following questions: (1) what is the purpose of the time limit? (2) how long was the delay? (3) is there a good explanation for the delay? (4) what will be the consequences for the parties of an extension of time? and (5) what will be the consequences for the parties of a refusal to extend time? The court or tribunal then makes its decision in the light of the answers to those questions…”
“We consider that the guidance given at paras 40 and 41 of Mitchell remains substantially sound. However, in view of the way in which it has been interpreted, we propose to restate the approach that should be applied in a little more detail. A judge should address an application for relief from sanctions in three stages. The first stage is to identify and assess the seriousness and significance of the “failure to comply with any rule, practice direction or court order” which engages rule 3.9(1). If the breach is neither serious nor significant, the court is unlikely to need to spend much time on the second and third stages. The second stage is to consider why the default occurred. The third stage is to evaluate “all the circumstances of the case, so as to enable [the court] to deal justly with the application including [factors (a) and (b)]”. …”
“44... 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”
“In the context of an appeal right which must be exercised within 30 days from the date of the document notifying the decision, a delay of more than three months cannot be described as anything but serious and significant.”
“33. The explanation for the delay was honest but does not present a good reason for the delay. It is true that human error and oversight will occur but sometimes we have to live with the consequences of the error. Not realising the time and missing the train does not mean the train should have waited for me – I have missed the train and must accept the consequences of that.”
