Hopwood v The Queen, Byrnes v The Queen

These matters concerned appeals against convictions for murder. The applicants, Hopwood and Byrnes, were convicted of murder in separate trials. Both applicants sought leave to appeal their convictions to the High Court of Australia.

The central legal issue before Callinan J, sitting in chambers, was whether the applicants had established an arguable case of error in the decisions of the lower courts that warranted granting leave to appeal to the High Court. This involved a consideration of whether any substantial question of law or public importance was raised by the grounds of appeal.

Callinan J considered the grounds of appeal advanced by each applicant. For Hopwood, the grounds related to alleged misdirections by the trial judge concerning the onus of proof and the definition of murder. For Byrnes, the grounds concerned the admissibility of certain evidence and the adequacy of the summing up. After reviewing the material, Callinan J concluded that neither applicant had demonstrated an arguable case of error sufficient to justify the grant of special leave to appeal to the High Court.

Consequently, Callinan J dismissed the applications for leave to appeal.
