Smith v The State of Western Australia

Smith (the applicant) sought leave to appeal against a decision of the Court of Appeal of Western Australia, which had dismissed his appeal against his conviction for murder. The central dispute concerned the admissibility of certain evidence obtained during police investigations.

The High Court was required to determine whether the evidence, specifically statements made by the applicant to police, had been improperly obtained, thereby rendering it inadmissible under section 138 of the *Evidence Act 1906* (WA). This involved considering whether the conduct of the police in obtaining the statements was unlawful or unfair, and whether the probative value of the evidence outweighed any prejudice it might cause.

The Court considered the principles governing the admissibility of improperly or illegally obtained evidence, particularly in light of the discretion afforded to trial judges under section 138. It analysed the nature of the police conduct, the circumstances under which the statements were made, and the potential impact on the fairness of the trial. The Court ultimately found that the evidence was admissible, applying established principles of evidence law.

Leave to appeal was refused.
