Bank Nationalisation Case

The Bank Nationalisation Case, also called Bank of New South Wales v Commonwealth (1948) 76 CLR 1, is a 1948 decision of the High Court of Australia (upheld on appeal to the Privy Council) that invalidated Chifley government legislation that attempted to nationalise the private banking sector. Separate majorities held that the legislation breached three different provisions of the Constitution: section 92 (requiring trade and commerce between the states to be "absolutely free"), section 51(xxxi) (requiring compulsory acquisition of property to be "on just terms") and section 75(iii) (which grants the High Court original jurisdiction in cases where the Commonwealth is sued).

A subsequent appeal application by the Commonwealth to the Privy Council was dismissed on jurisdictional grounds. The Board held that the case involved potential questions around the limits of the powers between the Commonwealth and the states and hence they were precluded from hearing the case under section 74 of the Constitution. However, the Board did affirm that the legislation breached section 92 of the Constitution, thus endorsing the individual right interpretation of the section. Additionally, the Board formulated its own test for when section 92 would be breached. This test was adopted and applied by the High Court until 1988, where in the case of Cole v Whitfield the section was reinterpreted as a prohibition on protectionist legislation.

The case rendered a key pillar of Labor's economic policy unworkable and possibly was influential in the eventual defeat of the government in 1949. Labor remained in opposition for 23 years and with nationalisation no longer an option, the party moved towards less direct methods to achieve its social and economic goals. The use of tied grants to the states (section 65) and the external affairs power (section 51(xxix)) were later utilised by governments, beginning with the Whitlam government in 1972.
