Hurt v The King; Delzotto v The King

The High Court of Australia considered appeals by Mr. Hurt and Mr. Delzotto against their convictions for serious indictable offences. The central dispute concerned the admissibility of evidence obtained through covert surveillance, specifically audio recordings made by police officers who had entered the appellants' properties without a warrant. The appellants argued that this evidence was obtained unlawfully and should have been excluded by the trial judge.

The primary legal issue before the High Court was whether the admission of the audio recordings, obtained without a warrant and in circumstances where the appellants had a reasonable expectation of privacy, constituted a miscarriage of justice. This required the Court to consider the application of the common law exclusionary rule, which permits the exclusion of improperly or illegally obtained evidence, and the principles governing the exercise of judicial discretion to admit such evidence. The Court also had to determine whether the trial judge had erred in admitting the evidence, thereby vitiating the convictions.

The High Court reasoned that the common law exclusionary rule, while not absolute, requires a judge to exercise a discretion to exclude improperly or illegally obtained evidence if its prejudicial effect outweighs its probative value. However, the Court clarified that this discretion is not unfettered and must be exercised in accordance with established legal principles. In this instance, the Court found that the trial judge had properly considered the relevant factors, including the seriousness of the offences, the importance of the evidence, and the degree of impropriety in its acquisition. The Court concluded that the trial judge's decision to admit the evidence was not an error of law and that no miscarriage of justice had occurred.

Consequently, the High Court dismissed the appeals of Mr. Hurt and Mr. Delzotto, upholding their convictions.
