Separation of Powers in Australia

This article argues that the nature and character of separation of powers in Australia has been fundamentally shaped and defined by the High Court, which chose a Blackstonian, common law conception of separation of judicial powers in preference to the principles elaborated in The Federalist and articulated in the American Constitution. But the Court's recent jurisprudence, including its admission that it makes the law, has presented unprecedented theoretical and political challenges to the concept of separation of judicial power in Australia, including a transformation in the role of the attorneygeneral, the creation of new institutions and a move towards an American conception of checks and balances. Thus this article suggests that the Court continues to exercise a profound influence on the formulation of separation of powers in Australia.
