Lang v The Queen

The High Court of Australia considered an appeal by Mr Lang against his conviction for a criminal offence. The central dispute concerned the admissibility of certain evidence obtained by law enforcement officers.

The primary legal issue before the Court was whether the evidence, which was obtained following an alleged unlawful search and seizure, should have been excluded from trial. This required the Court to consider the application of the exclusionary rule and the principles governing the admission of evidence obtained in contravention of legal rights.

The Court analysed the circumstances surrounding the acquisition of the evidence, paying close attention to the relevant provisions of the *Crimes Act 1914* (Cth) and the common law. It applied established principles regarding the discretion of a trial judge to exclude evidence where its prejudicial effect outweighs its probative value, and where the evidence was obtained improperly or in contravention of law. The Court considered whether the impropriety in obtaining the evidence was so significant as to warrant its exclusion, even if it was relevant and probative.

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