R v Dupas (No 3)

In the case of R v Dupas (No 3), the appellant, Dupas, was convicted of the murder of a woman and appealed against his conviction to the High Court of Australia. The primary issues before the Court were whether the pre-trial publicity had prejudiced the trial proceedings to such an extent that it caused a miscarriage of justice, and if the judge erred in not ordering a permanent stay of the trial. Other legal issues included the adequacy of the judge’s directions regarding identification evidence and the use of consciousness of guilt evidence. Additionally, the Court considered whether the judge had correctly instructed the jury regarding the evidence of a prison informer and the overall balance of the charge against Dupas.

The High Court found that the judge’s refusal to permanently stay the trial was not an error, as the publicity did not reach the threshold of causing a miscarriage of justice. However, the Court held that the judge had not provided adequate directions to the jury about the Domican warning, which relates to the reliability of identification evidence. Furthermore, the Court found that the judge should have given an Edwards direction regarding other post-offence conduct, which might have impacted the jury’s assessment of the evidence. The Court also determined that the judge’s directions concerning the evidence of the prison informer, pursuant to the Pollitt warning, were inadequate. Finally, the Court concluded that the verdict was unreasonable, leading to the allowance of the appeal and the ordering of a retrial.

The Court ordered that the application be granted, the appeal allowed, and a new trial be held. This decision underscores the importance of proper judicial direction on various types of evidence and the threshold for a permanent stay due to pre-trial publicity. The High Court's ruling emphasises the necessity for meticulous adherence to legal protocols to ensure a fair trial, highlighting the significant implications of judicial error in criminal proceedings.
