Federation and the Development of Australian Law (1901–1986)

Introduction

The period from Federation in 1901 to the Australia Acts in 1986 is the formative era of Australian law, during which the constitutional framework established in 1901 was interpreted, elaborated, and transformed by the High Court and the political branches. This period saw the emergence of a distinct Australian legal identity, the gradual expansion of Commonwealth power at the expense of the States, the development of a national economy and welfare state, and the final severance of Australia’s remaining legal ties with the United Kingdom. The evolution of the High Court’s interpretive approach — from the legalism of the Dixon Court to the realism of the Mason Court and beyond — fundamentally shaped the trajectory of Australian law.

The Establishment of the High Court

The High Court of Australia was established in 1903 under s 71 of the Constitution. The first justices were Sir Samuel Griffith (Chief Justice), Sir Edmund Barton, and Richard Edward O’Connor. All three had been leading figures in the federation movement and the drafting of the Constitution. The early High Court adopted a textualist approach to constitutional interpretation, reading the Constitution according to its ordinary meaning. In its first decades, the Court was confronted with foundational questions about the federal balance, the scope of Commonwealth powers, and the relationship between the Commonwealth and the States.

Early Constitutional Cases

The first case of major significance was D’Emden v Pedder (1904) 1 CLR 91, in which the High Court applied the American doctrine of implied immunity of instrumentalities to invalidate a Tasmanian stamp duty on receipts issued to Commonwealth officers. Griffith CJ held that Commonwealth and State governments were “distinct and separate” and that neither could interfere with the governmental functions of the other. This approach was extended in the Union Label Case (Attorney-General (NSW) v Brewery Employés Union (1908) 6 CLR 469), where the Court held that the Commonwealth’s power over trade and commerce did not extend to intrastate trade.

The Engineers’ Case (Amalgamated Society of Engineers v Adelaide Steamship Co Ltd (1920) 28 CLR 129) was a watershed moment. The Court, led by Sir Isaac Isaacs and H B Higgins, rejected the implied immunity of instrumentalities and held that the Constitution should be interpreted according to its ordinary and natural meaning, without importing implications derived from American federalism. Knox CJ, Isaacs J, Higgins J, and Starke J held that Commonwealth laws enacted under s 51 applied to State governments and their instrumentalities unless the Constitution expressly provided otherwise. The Engineers’ Case fundamentally altered the federal balance, enabling the Commonwealth to apply its laws to the States and expanding the scope of Commonwealth legislative power.

The Growth of Federal Power

The subsequent decades saw a steady expansion of Commonwealth power through judicial interpretation. The uniform tax scheme of 1942, upheld in South Australia v Commonwealth (1942) 65 CLR 373 (the First Uniform Tax Case), gave the Commonwealth a dominant position in revenue collection by making Commonwealth grants conditional on the States not imposing income tax. The bank nationalisation case (Bank of New South Wales v Commonwealth (1948) 76 CLR 1) struck down the Chifley government’s attempt to nationalise private banks, but confirmed the broad scope of the corporations power. The Communist Party Case (Australian Communist Party v Commonwealth (1951) 83 CLR 1) invalidated legislation dissolving the Communist Party, with Dixon J famously stating that the Constitution is “an instrument framed in accordance with many traditional conceptions” and that the judiciary must guard against legislative encroachment on individual liberty.

The Melbourne Corporation case (1947) re-established a limited implied immunity for the States, prohibiting the Commonwealth from discriminating against the States or curtailing their capacity to function as independent governments. The Tasmanian Dam Case (1983) expanded the external affairs power to encompass the implementation of any international treaty, enabling the Commonwealth to legislate on matters of traditional State responsibility through the mechanism of treaty implementation.

The Evolution of the High Court

The High Court has passed through several distinct phases in its interpretive approach. The Dixon Court (1952–1964), led by Sir Owen Dixon, was the high-water mark of legalism — the approach that the court should decide cases by the strict application of legal rules without regard to policy consequences. Dixon famously declared that “there is no other safe guide to judicial decisions than strict and complete legalism.” The Dixon Court was characterised by close textual analysis, adherence to precedent, and a relatively narrow construction of Commonwealth powers.

The Barwick Court (1964–1981) continued the legalist tradition but with a more centralist tendency, favouring Commonwealth power in cases such as Strickland v Rocla Concrete Pipes Ltd (1971) 124 CLR 468 (expanding the corporations power). The Mason Court (1987–1995) marked a significant shift towards legal realism, with the Court acknowledging the role of policy and values in constitutional adjudication. The Mason Court recognised the implied freedom of political communication, expanded the scope of the external affairs power, and developed the Kable doctrine protecting the institutional integrity of State courts. The Gleeson Court (1998–2008) and the French Court (2008–2017) moved towards a more textualist approach, emphasising the text and structure of the Constitution over implied rights and freedoms.

The Australia Acts 1986

The Australia Acts 1986 represent the final severance of Australia’s constitutional ties with the United Kingdom. The Acts were passed in identical terms by the Commonwealth Parliament and the United Kingdom Parliament, at the request of the States. The Australia Act 1986 (Cth) and the Australia Act 1986 (UK) had several critical effects: (1) they terminated the power of the UK Parliament to legislate for Australia, including the States; (2) they abolished all appeals to the Judicial Committee of the Privy Council from Australian courts; (3) they confirmed that the States possess full legislative independence, subject only to the Commonwealth Constitution; and (4) they provided that the royal prerogative with respect to the States is exercisable only by the Governor of the State, not by the Queen personally (subject to certain exceptions).

The Australia Acts 1986 resolved the long-standing anomaly that the States remained subject to Imperial legislative power even after the Statute of Westminster 1931 had granted legislative independence to the Commonwealth. The Acts also completed the process of judicial independence by ending the right of appeal to the Privy Council, which had already been restricted in 1975 in relation to decisions of the High Court. The Mabo decision of 1992, which recognised native title, was the first major High Court decision that could not be appealed to the Privy Council, symbolising the complete independence of Australian law.

The Republic and Voice Referendums

The 1999 Republic referendum proposed the replacement of the Queen and Governor-General with a President appointed by a two-thirds majority of Parliament. The proposal was defeated, with 45.13 per cent voting “yes.” The defeat reflected divisions among republicans about the appointment method and a residual attachment to the existing constitutional monarchy. The 2023 Voice to Parliament referendum proposed the establishment of an Aboriginal and Torres Strait Islander Voice to advise the Parliament and Executive. This proposal was also defeated, with 39.9 per cent voting “yes.” The failure of these referendums demonstrates the difficulty of constitutional amendment in Australia and the conservative character of the Australian electorate on constitutional questions.
