When determining whether to grant leave to appeal, the test is whether there are reasonable prospects of success in the intended appeal, not the merits of the appeal itself. Where there are material contradictions in a complainant's evidence (particularly between a statement to police and court testimony), where the trial court itself found the complainant unimpressive and noted contradictions and exaggerations, and where the medical evidence does not support the complainant's version of events, there are reasonable prospects that another court may reach a different conclusion. In such circumstances, leave to appeal should be granted.
