Conway v The Queen

The case of *Conway v The Queen* involved an appeal to the High Court of Australia concerning the conviction of the appellant for murder. The prosecution's case alleged that the appellant, a police officer, procured the murder of his estranged wife, with the assistance of two co-offenders, Williams and Steer, and his de facto partner, McFie. The central dispute revolved around the directions given by the trial judge to the jury regarding the evidence of the co-offenders, who were considered unreliable witnesses.

The legal issues before the High Court included whether the trial judge had misdirected the jury concerning the corroboration of evidence given by co-offenders, and whether such a misdirection, if established, necessitated a new trial under the *Evidence Act 1995* (Cth). The Court was required to consider the application of the "proviso" in appellate law, which allows an appeal to be dismissed despite a misdirection if no substantial miscarriage of justice has occurred.

The High Court, in dismissing the appeal, reasoned that while there was a material misdirection in the trial judge's summing up regarding the corroboration of the co-offenders' evidence, this error did not occasion a substantial miscarriage of justice. The Court found the prosecution's case against the appellant to be overwhelming, particularly due to a recorded conversation between the appellant, McFie, Williams, and Steer. This recording, which captured the appellant responding to inculpatory suggestions from the co-offenders, was considered highly persuasive evidence of his involvement in the murder. The Court applied the principle that an appellate court may refuse to order a new trial if an established error could not reasonably have influenced the result, concluding that the appellant's conviction was inevitable given the totality of the evidence.
