The binding principle is that in an application for leave to appeal to the Supreme Court under section 44 of the High Court Act, the court must be satisfied that there are reasonable prospects of success on appeal. Where an accused was the driver of a vehicle used in the commission of a crime and cannot provide credible explanation for their presence, they cannot distance themselves from the criminal conduct of the group and may be convicted on the basis of common purpose. Circumstantial evidence linking the accused to the crime scene, including expert tracking evidence, material found in their possession, and false explanations, can be sufficient to sustain a conviction even where the accused was not directly observed committing the offence.
