The bases upon which this court will grant an application to extend time for leave to appeal against conviction and/or sentence are not in doubt. Those bases were conveniently summarised by Gowans J in the case of R v Darby and encapsulated in the reasons for judgment of the Full Court in the case of R v O'Keefe. They have been followed in this court subsequently in numerous applications, including R v Martin, R v Craker and other cases. As Gowans J said in the case of Darby:
The principles which govern an application for extension of time are as follows:
(1) the prescription by the statute of the time limit for giving notice is intended to secure finality, and compliance is intended to be required in the ordinary case;
(2) extension of the time is a matter for discretion of the Court, and the applicant must put material and considerations before the Court which will persuade it to exercise its discretion in favour of an extension;
(3) rigid restrictions cannot be imposed on the exercise of discretion, but in general the Court will require special and substantial reasons for extending the time;
(4) the longer the time which elapses since the expiration of the statutory period and the more the changes that have taken place in the meantime, the more exceptional will the circumstances put before the Court have to be;
(5) it is the practice of the Court not to grant any considerable extension of time unless it is satisfied that there are such merits in the proposed appeal that it would probably succeed;
(6) a reasonably satisfactory account of the failure to comply with the statutory requirements needs to be forthcoming.
In the case of O'Keefe, the court, having referred to those principles set forth by Gowans J, went on (at 5 of the report):
An applicant who has been dilatory or has acted in such a way as to indicate that he does not intend to appeal has small, if any, claim to the exercise of the discretion of the Court in his favour. On the other hand, if the applicant has acted promptly, his case will be considered very differently. Where there has been a long delay the practice of the Court has not been to grant the extension sought unless it is clear that the decision is attended with such doubt as to make it probable that the appeal will succeed.[2]
