Nguyen and Anor v The Commissioner of the Australian Federal Police and Ors

This matter concerned an application before the High Court of Australia. The plaintiffs, represented by Mr G.D. Wendler, sought to challenge the constitutional validity of certain provisions of the *Proceeds of Crime Act*. The first defendant, the Commissioner of the Australian Federal Police, was represented by Mr A.S. McDougall, and the third defendant, the Commonwealth of Australia, was represented by Mr G.J.D. Del Villar. The second defendant, the Commonwealth of Australia, filed a submitting appearance.

The central legal issues before the Court revolved around the scope and application of section 77(iii) of the Australian Constitution, which empowers the Commonwealth Parliament to make laws investing State courts with federal jurisdiction. Specifically, the plaintiffs argued that the *Proceeds of Crime Act*, by vesting jurisdiction in State courts for the purpose of making examination orders and establishing a system involving "approved examiners" appointed by the Executive, either impermissibly altered the structure and nature of those State courts, contrary to the principle of taking the court as found, or engaged with the principles established in *Kable v Director of Public Prosecutions (NSW)*. The plaintiffs contended that this scheme effectively allowed a non-judicial federal officer to exercise significant authority within the State court's framework, potentially undermining the court's own jurisdiction and the rights of individuals.

The Court considered submissions regarding the appropriateness of proceeding by way of a special case, noting that the statement of claim required amendment to clearly articulate the factual basis for the constitutional challenges. The plaintiffs' primary arguments were that the *Proceeds of Crime Act* was effectively "transmogrifying" the structure of the Supreme Court of Queensland, thereby breaching the principle that federal jurisdiction is invested in State courts as they exist at the time of vesting. The alternative argument involved a potential conflict with the *Kable* doctrine, possibly with implications for section 80 of the Constitution. Despite some reservations about the clarity of the statement of claim, the Court ultimately made orders in accordance with a draft provided, listing the matter for further directions.
