Port Kembla Coal Terminal Ltd v Industrial Court of New South Wales

Port Kembla Coal Terminal Ltd (PKCT) sought judicial review of a decision of the Industrial Court of New South Wales. The dispute concerned the application of the *Workplace Relations Amendment (Work Choices) Act 2005* (Cth) to PKCT's employees, and whether this Commonwealth legislation rendered certain provisions of New South Wales industrial law inoperative due to inconsistency. The matter came before the Supreme Court of New South Wales, constituted by Spigelman CJ, Beazley JA, and Handley AJA.

The central legal issues before the Court were whether the *Workplace Relations Amendment (Work Choices) Act 2005* (Cth) covered the field of industrial relations to the extent that it evinced an intention to exclusively regulate the subject matter, thereby precluding the operation of the relevant New South Wales legislation. Alternatively, the Court was required to determine if there was a direct inconsistency between the Commonwealth and State laws, particularly in light of any temporal distinctions in their application, which would render the State law invalid under section 109 of the Commonwealth Constitution.

The Court reasoned that the *Workplace Relations Amendment (Work Choices) Act 2005* (Cth) was intended to provide a comprehensive and uniform system of industrial relations regulation across Australia. It found that the Commonwealth legislation occupied the field of industrial relations, leaving no room for the operation of the inconsistent provisions of the New South Wales industrial laws. The Court applied the principles of constitutional law concerning the interpretation of section 109 of the Commonwealth Constitution, holding that where Commonwealth legislation evinces a clear intention to exclusively regulate a particular subject matter, any State law that touches upon that subject matter will be invalid to the extent of the inconsistency.

The summons was dismissed with costs.
