For leave to appeal to be granted, an applicant must establish on proper grounds that there are prospects of success that are not remote but have a realistic chance of succeeding, based on a sound rational basis - more than mere possibility, arguability, or that the case is not hopeless. Identification evidence must be approached with caution due to the fallibility of human observation, but where a witness knew the accused well, observed at close range with good lighting, and the identification is corroborated by immediate reports to others and physical evidence (such as matching clothing), such evidence can be accepted as reliable. When cross-examining on prior inconsistent statements, if the content is challenged or used to contradict the witness, the statement must be tendered as an exhibit for the court to properly assess alleged contradictions. False alibi evidence can support an inference that the accused has something to hide and was not where claimed at the material time.
