24 In my opinion, this is not a case in which the delay may be explained by exceptional circumstances or some untoward vicissitude of life which prevented the defendant from applying his mind to the question of appeal in the sense in which that test has been applied in the authorities. At the same time, it is an important consideration in this case that the delay has largely been caused by the lack of proper diligence by the defendant's solicitor rather than the defendant. That aspect of the test which involves a consideration of the merits of the proposed appeal has been expressed in a variety of ways in the authorities and it is no doubt linked to the length of the delay and the adequacy of the explanation provided by the defendant. In my opinion, bearing in mind the length of the delay and the explanation for the delay in this case, an extension of time should only be granted if there are substantial grounds for apprehending a miscarriage of justice if it is refused. For reasons I will give, I have reached the conclusion that the point raised in ground 4 satisfies that test, although it must be borne in mind that I am not hearing the appeal. Again, for reasons I will give, the other proposed grounds of appeal do not satisfy the test for granting leave to appeal. In other words, I do not think they are reasonably arguable.
