Knaggs v Commonwealth Director of Public Prosecutions

In the matter of Knaggs versus the Commonwealth Director of Public Prosecutions, the High Court of Australia addressed the validity of information laid against the appellant for tax evasion. The appellant argued that the information was defective due to the absence of an express reference to an element of the offence under section 8ZL of the Taxation Administration Act 1953, and sought to have the information quashed. The court was tasked with determining whether the mere reference to the relevant section of the Act in the information was sufficient, or if an explicit averment of each fact constituting the offence was required. Additionally, the court had to decide whether the lack of evidence of an element of the offence constituted a jurisdictional error.

The High Court found that the information was valid and not defective as it sufficiently referenced the relevant section of the Act. The Court held that while it is generally necessary to explicitly aver each fact constituting the offence, this requirement may be waived if the section of the Act is clearly referenced. In this instance, the reference to section 8ZL of the Taxation Administration Act 1953 was sufficient to satisfy the requirement. Furthermore, the Court found that the absence of evidence of an element of the offence did not constitute a jurisdictional error, as the requirement for evidence only arises at the trial stage.

The Court held that the information was valid, and the appeal was dismissed. The Court did not find it necessary to address the argument concerning section 146 of the Justices Act 1902, as it was not relevant to the outcome of the case. The Court found that the absence of an explicit averment of each fact constituting the offence did not render the information defective, provided that the relevant section of the Act was clearly referenced. The Court also held that the lack of evidence of an element of the offence was not a jurisdictional error, as the requirement for evidence only arises at the trial stage.
