State of New South Wales; State of Queensland; State of South Australia; State of Western Australia v The Commonwealth of Australia

The High Court of Australia heard a series of cases brought by the States of New South Wales, Queensland, South Australia, and Western Australia against the Commonwealth of Australia. The core dispute concerned the constitutional validity of the *Corporations Act*, specifically whether the Commonwealth possessed the legislative power to enact such legislation.

The legal issues before the Court included whether the Commonwealth had the power to legislate with respect to incorporation, whether this power had been correctly invoked in the *Corporations Act*, and the validity of specific sections of the Act, namely sections 112 and 113. The Court was also required to consider questions of apparent inconsistency arising from these sections.

The plaintiffs, represented by their respective counsel, argued that placitum (xx) of the Constitution, which grants the Commonwealth power to legislate with respect to certain matters, did not empower it to legislate on incorporation. The proceedings involved detailed submissions on the scope of this placitum and its application to the *Corporations Act*. One of the plaintiffs, Queensland, reached an agreement with the Commonwealth and discontinued its action, with its counsel then acting for South Australia.
