Clyde Engineering Co Ltd v Cowburn

This case involved appeals to the High Court of Australia concerning the validity of certain provisions of the New South Wales Forty-four Hours Week Act 1925 in relation to a Federal award made under the Commonwealth Conciliation and Arbitration Act 1904-1921. The primary dispute arose from employers deducting amounts from employee wages, asserting compliance with the State Act, while employees claimed entitlement to higher wages based on the Federal award. The appeals were brought by Clyde Engineering Co Ltd, Metters Ltd, and Lever Brothers Ltd against employees who had successfully claimed under the Federal award in lower courts.

The central legal issues before the High Court were whether sections 12 and 13 of the New South Wales Forty-four Hours Week Act 1925, which purported to alter the standard working hours and overtime entitlements for employees covered by Federal awards, were inconsistent with the Commonwealth Conciliation and Arbitration Act and the Federal awards themselves. Specifically, the Court had to determine the test for inconsistency between Commonwealth and State laws under section 109 of the Constitution and whether the State Act's provisions effectively amended or overrode the terms of a Federal award.

A majority of the High Court, comprising Knox C.J., Isaacs, Gavan Duffy, Rich, and Starke JJ., held that when a Federal award has been validly made, a State Parliament cannot alter its terms or impose rights and obligations inconsistent with it. The Court rejected the proposition that the possibility of obeying both laws without disobeying either was the sole test of inconsistency. Instead, it applied the principle that an inconsistency arises if a State law, when enforced, would destroy or vary the industrial relations adjustment established by a Federal award. Consequently, sections 12 and 13, and to the extent it applied to parties to Federal awards, section 6 of the New South Wales Act, were found to be invalid as they conflicted with the Commonwealth legislation and the Federal award. Higgins and Powers JJ. dissented.
