Schokman v Director of Public Prosecutions (NSW)

Schokman v Director of Public Prosecutions (NSW) concerned an appeal to the High Court of Australia by the appellant, Schokman, against a decision of the Director of Public Prosecutions (NSW). The core of the dispute revolved around the interpretation and application of certain provisions of the *Crimes Act 1900* (NSW) concerning the admissibility of evidence obtained through covert surveillance.

The High Court was required to determine whether evidence obtained by police officers, acting under a warrant issued pursuant to s 149 of the *Crimes Act 1900* (NSW), was admissible in subsequent criminal proceedings, notwithstanding that the warrant was allegedly executed in a manner that exceeded the scope of the authority granted. Specifically, the court had to consider whether the manner of execution of the warrant could render otherwise relevant and admissible evidence inadmissible on grounds of impropriety or illegality.

The court's reasoning focused on the distinction between the validity of the warrant itself and the lawfulness of its execution. It was held that the admissibility of evidence obtained under a valid warrant is generally not affected by the manner in which the warrant is executed, unless the execution itself renders the evidence unlawfully obtained in a way that engages exclusionary rules. The High Court affirmed that the focus of the court's inquiry should be on whether the evidence was obtained in contravention of a specific legal prohibition that mandates its exclusion, rather than on a general notion of impropriety. The court considered the principles governing the admissibility of evidence obtained in breach of statutory provisions and the discretion of the court to exclude evidence on public policy grounds.

The appeal was dismissed, with the High Court upholding the admissibility of the evidence in question.
