Deane and Toohey JJ said at 490:
"Quite apart from the nature of a particular grant of legislative power, the Constitution's doctrine of the legal equality of the people of the Commonwealth must be adjusted to the extent necessary to accommodate discriminatory treatment which other provisions of the Constitution clearly contemplate. Thus, the Constitution, in providing for the exercise of the judicial power of the Commonwealth by both State and federal courts, implicitly contemplates the application, in the course of that exercise, of the different procedural laws, rules and practices of the courts concerned. Those different procedural laws, rules and practices may, in some circumstances, be of critical importance to the outcome of litigation, including criminal proceedings. Nonetheless, the doctrine of the legal equality of the people of the Commonwealth must be adjusted to accommodate them at least to the extent that the application of the procedural laws, rules and practices of a particular court is a necessary concomitant of the vesting by the Parliament of part of the judicial power of the Commonwealth in that court."
