Constitutional commentators have long been troubled by the question as to whether the notion of the rule of law operates, on the one hand, as a conduit for the expression of the supreme legislative authority of Parliament, or, on the other (at least to some degree) independently of, and thereby potentially in conflict with, parliamentary supremacy. As an alternative to both of these suggestions it might be held that according to the circumstances, the notion of the rule of law is capable of portraying both of these characteristics. Curiously, relatively little has been written on this specific issue in relation to Australia. The attention directed towards the vexed questions of the nature and extent of the federal division of powers in Australia (admittedly, themselves issues not unrelated to the present concern) has marginalised interest in the nature of legislative authority in Australia. “The one legal doctrine”, it has been recently proclaimed, “that Australian and other Commonwealth lawyers are never taught to question (or perhaps are taught never to question) is A V Dicey's theory of parliamentary omnipotence”.
