Kenan Director of Public Prosecutions

This matter concerned an appeal by the Director of Public Prosecutions (DPP) against a decision of the Supreme Court of New South Wales. The DPP sought to challenge the acquittal of the respondent, Mr Kenan, on charges of conspiracy to defraud. The core of the dispute revolved around the admissibility of certain evidence obtained during the investigation.

The primary legal issue before the High Court was whether the evidence, which included documents and statements obtained from the respondent under compulsion, was admissible in subsequent criminal proceedings against him. This raised questions concerning the scope and application of privilege against self-incrimination and the interpretation of statutory provisions governing the use of compelled evidence.

Deane and Gaudron JJ held that the privilege against self-incrimination, a fundamental common law right, was not abrogated by the legislation under which the evidence was compelled. Their Honours reasoned that the statutory provisions did not expressly or by necessary implication remove this protection. Consequently, the compelled evidence, and any evidence derived from it, was inadmissible against the respondent in the criminal proceedings. The court affirmed that the privilege could only be displaced by clear and unambiguous statutory language.
