Hewitt v The Queen

In *Hewitt v The Queen*, the High Court of Australia considered an appeal by the applicant, Hewitt, against his conviction for murder. The dispute centred on the admissibility of certain evidence and the fairness of the trial process.

The High Court was required to determine whether the trial judge had erred in admitting evidence obtained from the applicant following his arrest, and whether the trial judge had adequately directed the jury on the issue of self-defence. A further issue concerned the proper application of the *Criminal Appeal Act 1912* (NSW) in relation to the admission of evidence.

The Court held that the evidence obtained from the applicant after his arrest was improperly admitted, as it was obtained in circumstances where the applicant had not been properly cautioned. Brennan CJ and Dawson J, in separate judgments, found that the admission of this evidence had occasioned a substantial miscarriage of justice, leading to the quashing of the conviction. Kirby J, while agreeing that the conviction should be quashed, reached this conclusion on different grounds, focusing on the cumulative effect of errors during the trial. The legal principle applied was that evidence obtained in breach of statutory requirements, particularly regarding cautions, may be inadmissible if its admission would be unfair or lead to a miscarriage of justice.

The High Court ordered that the appeal be allowed, the conviction be quashed, and that a new trial be held.
