Maxwell v The Queen

In *Maxwell v The Queen*, the High Court of Australia considered an appeal against a conviction for murder. The appellant, Maxwell, had been found guilty by a jury in the Supreme Court of Victoria and sentenced to imprisonment for life. The appeal to the High Court concerned the fairness of the trial process and the admissibility of certain evidence.

The central legal issues before the High Court were whether the trial judge had erred in admitting evidence obtained in breach of a statutory prohibition, and whether the admission of this evidence, if unlawful, had occasioned a miscarriage of justice. Specifically, the court had to determine the proper application of s 138 of the *Evidence Act 2008* (Vic) (which was in force at the time of the appeal, though the trial predated its commencement and the common law principles were applied) concerning the exclusion of improperly or illegally obtained evidence, and the test for determining whether such an error would lead to a quashing of the conviction.

The High Court, applying the principles of the common law as they existed prior to the enactment of s 138, held that the evidence in question had been obtained unlawfully. However, the Court then considered whether the admission of this evidence had resulted in a miscarriage of justice. Applying the proviso to s 6(1) of the *Criminal Appeal Act 1915* (Vic) (which mirrors the proviso in s 6(1) of the *Criminal Appeal Act 1907* (UK) and s 237 of the *Criminal Code* (Cth)), the Court determined that, despite the error in admitting the evidence, there was no reasonable doubt that the jury would have convicted the appellant even if the evidence had been excluded. The Court found that the other evidence against Maxwell was so strong that the improperly obtained evidence did not have a decisive influence on the jury's verdict.

Consequently, the High Court dismissed the appeal and upheld the conviction.
