Chen (Yan Ping) v Director of Public Prosecutions

The case of Chen (Yan Ping) v Director of Public Prosecutions concerned an appeal against an interlocutory order dismissing an application for a permanent stay of proceedings. The appellant, Chen, sought relief in the nature of certiorari and a declaration, arguing that the decision to summon him to give evidence before an Inspector of the Crime Commission was flawed. The appeal was brought pursuant to the Crimes (Appeal and Review) Act 2001 (NSW), s 53(3)(b), and the Supreme Court Act 1970 (NSW), ss 69, 75. The central legal issue was whether the signature of the Inspector was a necessary requirement on the written notice summoning the appellant to give evidence and whether the delegation of the decision to summon a witness was permissible.

The court considered the statutory provisions governing the summoning of witnesses and the delegation of authority. It concluded that the signature of the Inspector was not a mandatory requirement for the validity of the notice under the Crime Commission Act 2012 (NSW), s 64, as the statute did not explicitly mandate the Inspector's signature. Additionally, the court held that the decision to summon a witness could be delegated to a solicitor assisting the Inspector, as long as the delegation was within the scope of the authority granted by the relevant legislation. The court found no error in the reasoning of the lower court and dismissed the appeal. Consequently, the appellant's application for a permanent stay of proceedings was rejected, and the relief sought was refused.
