fixing function of the Australian Industrial Relations Commission was removed and given to the newly created Australian Fair Pay Commission in 2006 as part of the WorkChoices amendments. Both the Australian Industrial Relations Commission and the Australian Fair Pay Commission were dissolved in 2009, to be succeeded by Fair Work Australia in 2010, and renamed the Fair Work Commission in 2012. Industrial Relations Act 1988 The 1904 Act was amended many times before being repealed by the Industrial Relations (Consequential Provisions) Act 1988 with effect on 1 March 1989, and superseded by the Industrial Relations Act 1988. The Industrial Relations Act 1988 was amended by the Industrial Relations Reform Act 1993, which adopted a decentralised labour law model with support for collective bargaining, rather than the centralised wage-fixing model adopted since the 1970s and formalised under the Prices and Incomes Accord between the Hawke Labor government and the Australian Council of Trade Unions. Workplace Relations Act 1996: WorkChoices In 1996, the Howard Government passed the Workplace Relations Act 1996, which replaced the Hawke Government's Industrial Relations Act 1988, with effect on 1 January 1997. The 1996 Act was substantially amended by the Workplace Relations Amendment (Work Choices) Act 2005, (aka Work Choices Act 2005) which came into effect on 27 March 2006, introducing WorkChoices. The 2005 Act used the corporations power to override state systems and unify industrial relations systems under a federal umbrella. In modern Australia, where the corporation is almost ubiquitous in business, that effectively meant the corporations power could be used to make laws about almost all employment relationships. As a consequence, WorkChoices had effective control of 85% of the employees in the Australian workforce. The changes created a separate Australian Fair Pay Commission to set wages, and enhanced powers for the Office of the Employment Advocate and a corresponding lesser role for the Australian Industrial Relations Commission. The constitutional validity of the WorkChoices legislation was challenged in the High Court in New South Wales v Commonwealth. The Court decided by a majority of 5–2 in November 2006 that all the WorkChoices reforms were valid. This was a landmark decision in Australian constitutional law and in Australian federal-state relations, confirming that the width of the scope of the Commonwealth's power in relation to corporations. A 2008 amendment to WorkChoices further expanded the federal government's reach into employer-employee relations when it prohibited awards which were determined by reference
