Walker v The Queen

In the case of Walker v The Queen, the appellant sought to appeal his conviction on the basis that the trial judge had failed to discharge the jury after hearing evidence of the appellant's bad character and had not issued a warning about the reliability of a witness under section 165 of the Evidence Act 2008. The court of appeal was tasked with determining whether the trial judge's decisions had resulted in a substantial miscarriage of justice and whether the failure to give a warning under section 165 constituted a significant error.

The primary legal issues the court addressed were whether the trial judge's refusal to discharge the jury and to issue a warning under section 165 constituted a substantial miscarriage of justice and whether the failure to issue the warning was a significant error. The court examined the trial judge's reasoning and the potential impact of the evidence on the jury's decision-making process. The court also considered the circumstances under which a warning under section 165 should be given and whether the failure to do so in this case warranted a retrial.

The court found that the trial judge's decisions did not result in a substantial miscarriage of justice, but that the failure to issue a warning under section 165 was a significant error. The court noted that while the evidence of the appellant's bad character and the witness's unreliability were important, they did not undermine the overall fairness of the trial. However, the court concluded that the failure to give a warning under section 165 was a significant error that required a retrial. The court also made observations about the Director’s discretion in deciding whether to issue such a warning, emphasising the importance of considering the specific circumstances of each case.

The court allowed the appeal and ordered a retrial, noting that while the failure to issue a warning under section 165 was a significant error, it did not necessarily mean that the conviction was unsafe and unsatisfactory. The court highlighted the importance of ensuring that the trial process is conducted fairly and that all relevant factors are considered by the jury. The court did not specify any particular orders beyond ordering a retrial, leaving the details of the retrial to be determined by the trial court.
