on the 'conciliation and arbitration' power. The new legislation applies to all employees of a "constitutional corporation." A constitutional corporation is a corporation within the meaning of section 51(xx) of the Constitution. The legislation also applies to employees of the Commonwealth and its agencies, and some others. The expected coverage of this law is approximately 85% of the Australian workforce. That proportion is likely to increase as employers who operate as sole traders or in partnerships incorporate to take advantage of the new legislation's relatively "employer-friendly" provisions. On 14 November 2006, the High Court by a 5-to-2 majority upheld the validity of the WorkChoices legislation against all the challenges that had been made to it in an action brought by each of the States and mainland Territories, as well as certain trade unions. The single majority judgment, while it did not expressly adopt, waved aside all the objections that had been argued against the "object of command" test for the validity of the exercise of the corporations power.

If this is correct, then given the preponderant role of corporations in the modern economy, the possibility exists for substantial Federal control of the greater part of the economy, with little if any regard to the traditional constitutional "heads of power". Protection of rights Access to the High Court To a very large extent, the Constitution leaves it to Parliament to determine both the High Court's original jurisdiction (section 76), and the exceptions to, and conditions on, its power to hear appeals (section 73).

This includes matters in which "a writ of Mandamus or prohibition or an injunction is sought against an officer of the Commonwealth". In recent years, the Parliament has all but eliminated the possibility of appeal against many decisions in the area of migration, especially in regard to applications for refugee status. However, since the Parliament is not constitutionally able to limit or abolish access to the High Court for the purpose of applying for
