Kable v Director of Public Prosecutions (NSW) [1996] HCA 24

Kable v Director of Public Prosecutions (NSW) [1996] HCA 24

The ratio decidendi is that Chapter III of the Constitution prohibits State Parliaments from conferring upon State courts powers that are incompatible with their exercise of federal judicial power. The Community Protection Act 1994 (NSW), in conferring upon the Supreme Court a power to order preventive detention of the appellant for predicted future conduct and applying only to him, in a manner contrary to fundamental judicial process and the requirements of equal justice and institutional integrity, was incompatible with the exercise of such judicial power and therefore invalid.
