Edwards v The Queen

The High Court of Australia considered an appeal by Mr Edwards against a conviction for sexual offences. The central dispute concerned the prosecution's disclosure of a "Cellebrite Download," an electronic database containing data extracted from the appellant's mobile phone. The prosecution had informed the appellant's legal representatives of the existence of this download prior to trial but had not provided a copy of its contents. The appellant argued that this failure constituted a miscarriage of justice.

The legal issues before the court were whether the prosecution had failed to provide full and proper pre-trial disclosure as required by section 142 of the *Criminal Procedure Act 1986* (NSW), specifically concerning material that might be relevant to the prosecution or defence case or the reliability of a prosecution witness. The court also considered whether the non-provision of the Cellebrite Download had caused a miscarriage of justice, thereby warranting the quashing of the verdict.

The High Court reasoned that while it would accord with good prosecutorial practice to provide a copy of such a download, the appellant had failed to demonstrate how the non-disclosure of the Cellebrite Download had adversely affected his entitlement to a fair trial. Despite having access to the download after conviction, the appellant could not identify specific material within it that would reasonably be regarded as relevant to the prosecution or defence case, or to the reliability of the complainant, beyond mere speculation. The court noted that the appellant's arguments regarding potential avenues for further investigation or cross-examination based on the download's contents were not sufficiently substantiated.

Consequently, the High Court concluded that the verdict against the appellant was not affected by a miscarriage of justice. The appeal was therefore dismissed.
