“[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. … [37] In my judgment, the approach of considering the overriding objective and all the circumstances of the case, including the matters listed inCPR r 3.9 , is the correct approach to adopt in relation to an application to extend time pursuant to s 83G(6) of VATA. The general comments in the above cases will also be found helpful in many other cases. Some of the above cases stress the importance of finality in litigation. Those remarks are of particular relevance where the application concerns an intended appeal against a judicial decision. The particular comments about finality in litigation are not directly applicable where the application concerns an intended appeal against a determination by HMRC, where there has been no judicial decision as to the position. None the less, those comments stress the desirability of not re-opening matters after a lengthy interval where one or both parties were entitled to assume that matters had been finally fixed and settled and that point applies to an appeal against a determination by HMRC as it does to appeal against a judicial decision.”
“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)]”. …”
“permission to appeal out of time should only be granted exceptionally, meaning that it should be the exception rather than the rule and not granted routinely.”
