The binding legal principles established are: (1) The test for granting leave to appeal is whether there is a reasonable prospect of success on appeal and whether there are any other reasons why an appeal should be heard. (2) To satisfy the test of reasonable prospects of success, an appellant must show more than a mere possibility of success or that the case is arguable; there must be a probability of success - a realistic chance of succeeding based on a sound, rational basis. (3) The onus rests on the appellant to demonstrate reasonable prospects of success. (4) In evaluating evidence of young children in sexual offence cases, while cautionary rules apply, contradictions arising from the passage of time and the children's age do not necessarily destroy the credibility of their evidence. (5) Independent corroboration, such as separate disclosures made at different locations on the same day, can support the credibility of child complainants and rebut allegations of collusion. (6) Courts must exercise common sense and not allow the exercise of caution or formalism to displace proper reasoning when evaluating evidence.
