Dalton v NSW Crime Commission

The appellant, Mr. Dalton, appealed to the High Court of Australia against a judgment of the Court of Appeal of New South Wales. The dispute concerned the validity of a summons issued by the New South Wales Crime Commission, requiring Mr. Dalton to attend an inquiry. Mr. Dalton sought to avoid compliance with the summons, arguing it constituted an infringement of his liberty, and challenged the legal basis for its inter-State service. The High Court was therefore required to determine the constitutional validity of the *Service and Execution of Process Act 1992* (Cth) in relation to the coercive powers of State investigative bodies.

The central legal issue before the High Court was whether the constitutional power of the Commonwealth Parliament to legislate with respect to the service and execution throughout the Commonwealth of "civil and criminal process" extended to process issued by State bodies with purely investigative functions, rather than those in aid of an adjudicative function. The Court also considered whether this power was confined to the process of State courts. The appellant contended that the potential for infringement of liberty associated with extending such power to non-court bodies warranted a narrower construction of the constitutional provision, particularly given the proliferation of such bodies.

The High Court, in dismissing the appeal, reasoned that the term "civil and criminal process" in section 51(xxiv) of the *Constitution* was not confined to process issued by courts. The Court found that the *Service and Execution of Process Act 1992* (Cth) was a valid exercise of Commonwealth legislative power, and that a summons issued by a State commission of inquiry, such as the NSW Crime Commission, constituted "process" for the purposes of the Act. The Court rejected the argument that the constitutional meaning of "civil and criminal process" should be narrowed due to changing features of modern government, such as the proliferation of State non-court bodies. The Court affirmed the judgment of the Court of Appeal, holding that the appellant was required to comply with the Commission's summons.
