The High Court of Australia, in the 1990s, put forth a due process principle, which stated that the Commonwealth Parliament could not require or authorise a chapter III Court to exercise judicial power in a manner that is inconsistent with the essential character of a court or with the nature of judicial power. The High Court continues to endorse the due process principle in 2004, since it is not a radical principle, but simply an aspect of the increasingly influential doctrine of the separation of federal judicial power from legislative and executive power.
