Huddart, Parker & Co Pty Ltd v Moorehead

This case concerned appeals by Huddart, Parker & Co. Pty Ltd and William Thomas Appleton against their convictions in the Court of Petty Sessions for refusing to answer questions posed by the Comptroller-General of Customs. The questions were requested under section 15B of the *Australian Industries Preservation Act 1906* (as amended), following the Comptroller-General's belief that offences had been committed against various sections of the Act concerning trade in coal. The appellants argued that the relevant sections of the Act were unconstitutional and invalid, and that section 15B itself was invalid.

The High Court was required to determine the constitutional validity of sections 5, 8, and 15B of the *Australian Industries Preservation Act 1906*. Specifically, the Court had to consider whether these provisions, particularly those requiring compulsory answers to the Comptroller-General, unduly interfered with the internal trade and commerce of the States. Furthermore, the Court had to ascertain the scope of the Commonwealth Parliament's power under section 51(xx) of the Constitution to legislate with respect to foreign corporations and trading or financial corporations formed within the Commonwealth. The validity of the inquiry process under section 15B, in relation to the judicial power of the Commonwealth and the right to trial by jury, was also a central issue.

The Court, by majority, held that section 15B of the *Australian Industries Preservation Act 1906* was intra vires the Commonwealth Parliament and valid. It was determined that the inquiry authorised by this section was not an exercise of the judicial power of the Commonwealth, nor was it inconsistent with the right to trial by jury conferred by section 80 of the Constitution. The majority also found that such an inquiry was not an incident of the execution and maintenance of the provisions of the Constitution relating to trade and commerce under section 101. However, there was significant division regarding the scope of section 51(xx) of the Constitution. While the majority held that this section did not grant power to create corporations but was limited to legislating about existing foreign and trading or financial corporations, Griffith C.J. and Barton J. further limited this power to prohibiting or conditioning engagement in trade and commerce, rather than controlling lawful operations. O'Connor J. viewed the power as restricted to recognising corporations as legal entities, not regulating their business. Isaacs J., dissenting on this point, argued for a broader power to control the conduct of these corporations.

The Court also divided on the validity of sections 5 and 8 of the Act. A majority, including Griffith C.J. and Barton J., found these sections ultra vires the Commonwealth Parliament, holding that while section 51(xx) allowed for prohibition or conditioning of trade and commerce, it did not permit control over the operations of corporations lawfully engaging in such trade. Isaacs J. dissented, considering sections 5 and 8 a valid exercise of the Commonwealth's power. Higgins J. also found sections 5 and 8 invalid, characterising them as legislation concerning trade and commerce rather than corporations themselves. The appeals were dismissed, with the convictions upheld.
