Aslett v R

The case of Aslett v R involved an appeal by the defendant against his conviction for robbery. The central issue in the case was whether the trial judge erred in failing to discharge the jury due to the unreliability of the identification evidence provided by the complainant. The matter was heard in the High Court of Australia, which was asked to determine whether the trial judge's failure to adequately address the weaknesses in the identification evidence warranted a new trial.

The primary legal issue before the court was whether the trial judge's failure to discharge the jury and to properly direct them on the weight to be given to the identification evidence constituted a miscarriage of justice. The court needed to consider whether the judge's shortcomings meant that the defendant's conviction was not inevitable, which would necessitate a new trial under the proviso of the common law. The identification evidence was critical, as the only basis for convicting the defendant was the complainant's identification of him as the perpetrator.

The court found that the trial judge's omissions did indeed constitute a significant error. The judge failed to discharge the jury despite clear evidence that the identification process was flawed and unreliable. The High Court emphasised that when identification evidence is highly questionable, it is the trial judge's duty to ensure the jury understands the limitations of such evidence. The court also highlighted the displacement effect, where the tainted identification evidence overshadowed other evidence in the case, potentially leading to an unjust outcome. Given these deficiencies, the court concluded that the conviction was not inevitable, and the defendant was entitled to a new trial.
