Thorne v The Queen

In *Thorne v The Queen*, the High Court of Australia considered an appeal against a conviction for murder. The appellant, Thorne, had been found guilty of the murder of his wife, who had died from a single stab wound. The central issue on appeal concerned the admissibility of certain evidence obtained from the appellant by police.

The High Court was required to determine whether the trial judge had erred in admitting evidence of statements made by the appellant to police, and whether the admission of this evidence had occasioned a miscarriage of justice. Specifically, the court had to consider whether the statements were obtained in circumstances that rendered them inadmissible, particularly in light of the appellant's mental state at the time of questioning.

The Court held that the trial judge had erred in admitting the statements. Applying the principles established in *R v Swaffield* and *Pollard v The Queen*, the majority reasoned that the statements were not voluntary, as the appellant's mental impairment meant he was incapable of understanding the nature and consequences of what he was saying. The Court found that the admission of these involuntary statements was prejudicial to the appellant and had led to a miscarriage of justice.

Consequently, the High Court allowed the appeal, quashed the conviction, and ordered a new trial.
