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. Accordingly, the judgment suggests that, henceforth, it may be a sufficient basis of validity that Federal legislation be specifically addressed to constitutional corporations ("A constitutional corporation must...", "A constitutional corporation must not..."), without any additional requirement that the legislation also address some aspect of the status or activities of corporations which is specific to such entities. 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".
