New South Wales v Commonwealth (2006) — The WorkChoices Case
Introduction
New South Wales v Commonwealth (2006) 229 CLR 1 — the WorkChoices Case — is the High Court’s landmark decision on the scope of the corporations power (s 51(xx) of the Constitution). The decision upheld the Commonwealth’s Workplace Relations Amendment (Work Choices) Act 2005 (Cth), which relied almost entirely on the corporations power to establish a comprehensive federal industrial relations system covering the majority of Australian employers and employees.
Facts
In 2005, the Commonwealth government enacted the Workplace Relations Amendment (Work Choices) Act 2005 (Cth), which fundamentally restructured Australian industrial relations law. The legislation:
- Extended Commonwealth workplace relations regulation to constitutional corporations (including proprietary companies, public companies, and foreign corporations)
- Precluded State industrial relations systems from applying to employees of constitutional corporations
- Established the Australian Fair Pay Commission and Workplace Authority
- Restricted the role of unions and collective bargaining
- Introduced Australian Workplace Agreements (individual statutory agreements)
The Work Choices legislation was the most ambitious Commonwealth industrial relations reform in Australian history. It was based primarily on the corporations power (s 51(xx)), supplemented by other heads of power including the external affairs power (s 51(xxix)) and the conciliation and arbitration power (s 51(xxxv)).
The States of New South Wales, Victoria, Queensland, South Australia, and Western Australia (the plaintiff States) challenged the validity of the legislation, arguing that the corporations power did not extend to regulating the industrial relations of employees of constitutional corporations.
The Corporations Power
Section 51(xx) of the Constitution provides that the Commonwealth may legislate with respect to:
“Foreign corporations, and trading or financial corporations formed within the limits of the Commonwealth.”
The question was: what activities of corporations can the Commonwealth regulate under this power?
The High Court’s Decision
The High Court upheld the legislation by a 5:2 majority. Gleeson CJ, Gummow, Hayne, Heydon, and Crennan JJ formed the majority. Kirby and Callinan JJ dissented.
The Majority
The majority held that the corporations power is a plenary power over the subject matter of constitutional corporations. It extends to the regulation of the “rights and liabilities” of corporations, including the relationship between a corporation and its employees.
The majority identified the key principles:
The “distinctive character” test is not the sole test: In Re Pacific Coal Pty Ltd (2000) 203 CLR 346, the Court had suggested that the corporations power extended to laws regulating the “activities, functions, relationships, and business” of corporations. The WorkChoices majority confirmed this broader approach.
The power is plenary: The corporations power is a “head of power in its own right” — it is not limited to regulating the “external” activities of corporations or to matters that are “characteristically corporate.” The power extends to any law that has a “sufficient connection” to constitutional corporations.
The incidental power: The incidental power (implied from s 51(xx)) extends to the regulation of non-corporate parties where it is “necessary” for the effective regulation of corporate activities. Thus, the legislation could validly regulate the conduct of employees and unions in their dealings with constitutional corporations.
The majority rejected the argument that the corporations power should be read down to preserve the “federal balance” or to protect the States’ traditional role in industrial relations.
The Dissent
Kirby J dissented, holding that the corporations power should not be interpreted so broadly as to “obliterate” the federal distribution of powers. His Honour argued that the Work Choices legislation was a “fundamental alteration” of the constitutional compact that should not be permitted by judicial interpretation.
Callinan J also dissented, holding that the corporations power did not extend to the regulation of the employment relationship because employment was not a matter that was “distinctive” to corporations. His Honour expressed concern about the centralising effect of the majority’s interpretation.
The Scope of the Corporations Power
The WorkChoices decision established that the corporations power extends to:
- The internal management of corporations
- The trading activities of corporations
- The employment relationships of corporations
- The contractual relationships of corporations
- The tortious liabilities of corporations
The only limit is that the law must have a “sufficient connection” to constitutional corporations. This is a relatively low threshold.
Impact on the Federal Balance
The WorkChoices decision significantly altered the federal balance by:
Enabling a uniform national system: The Commonwealth could now regulate workplace relations for the vast majority of Australian employers, creating a “national system” of industrial relations.
Limiting State power: State industrial relations systems were confined to employers that were not constitutional corporations — primarily sole traders, partnerships, and State and local government employers.
Expanding Commonwealth power: The broad interpretation of the corporations power provided a basis for Commonwealth regulation in areas beyond industrial relations, including environmental regulation, consumer protection, and occupational health and safety.
Subsequent Developments
The Work Choices legislation was itself replaced by the Fair Work Act 2009 (Cth) following the election of the Rudd Labor government in 2007. However, the constitutional basis of the Fair Work Act remains the same — the corporations power as interpreted in WorkChoices.
The Fair Work Act has been upheld in subsequent challenges. In Attorney-General (SA) v Corporation of the City of Adelaide (2013) 249 CLR 1, the High Court confirmed that the corporations power extends to the regulation of corporate activities by reference to the WorkChoices framework.
Significance
The WorkChoices Case is significant for several reasons:
It resolved the scope of the corporations power: The decision ended decades of uncertainty about the reach of s 51(xx) and established that it is a broad, plenary power.
It enabled national industrial relations reform: The decision provided the constitutional foundation for Australia’s first genuinely national industrial relations system.
It shifted the federal balance: The broad interpretation of the corporations power significantly expanded Commonwealth legislative capacity at the expense of the States.
It constrained the States: The decision limited the capacity of the States to regulate the activities of corporations, confining State power to non-corporate entities and areas not covered by Commonwealth law.
Political Context
The Work Choices legislation was controversial politically as well as constitutionally. The 2007 federal election was fought substantially on industrial relations policy, with the Labor opposition promising to replace Work Choices with a more balanced system. The Fair Work Act 2009 (Cth) was the legislative manifestation of that promise, but it relied on the same constitutional foundation that the WorkChoices decision had established.
Conclusion
New South Wales v Commonwealth (2006) is a watershed in Australian constitutional law. The broad interpretation of the corporations power transformed Australian federalism and laid the constitutional foundation for the modern national industrial relations system. The decision confirmed the plenary character of Commonwealth power under s 51(xx) and significantly limited the industrial relations competence of the States.
