In criminal cases where identification is in issue, it is not sufficient for the court to make a bald statement that the accused was "properly identified" without examining the reliability of the observation. The court must assess various factors including lighting, visibility, eyesight, proximity of the witness, opportunity for observation, extent of prior knowledge of the accused, and whether an identification parade was conducted. These factors must be weighed against each other in light of the totality of the evidence and the probabilities. Where witnesses did not know the assailant prior to the offence, identification occurred briefly in poor lighting conditions, and no identification parade was conducted, it is unsafe to sustain a conviction based on identification evidence. There is no onus on an accused to prove an alibi; if on all the evidence there is a reasonable possibility that the alibi is true, the accused is entitled to be acquitted. For a conviction of attempted rape, there must be evidence that the accused reached a stage of attempting to commit the offence; the accused's intention must be discernible from the evidence.
