State of NSW v Kable

The High Court of Australia considered the constitutional validity of a New South Wales law, the *Crimes (Forensic Procedures) Act 2000* (NSW), which permitted the taking of forensic samples from a convicted person, Mr Kable, for the purpose of investigating unsolved crimes. The State of New South Wales sought to uphold the validity of this legislation against Mr Kable's challenge.

The central legal issue before the High Court was whether the *Crimes (Forensic Procedures) Act 2000* (NSW) contravened Chapter III of the Australian Constitution, specifically by impermissibly entrenching upon the judicial power of the Commonwealth. The Court was required to determine if the Act, in authorising the taking of samples for the investigation of past unsolved crimes, constituted an exercise of judicial power by the executive or legislature, or if it unduly interfered with the functioning of the courts.

The majority of the High Court held that the Act was constitutionally invalid. Their reasoning focused on the principle that Chapter III of the Constitution vests the judicial power of the Commonwealth exclusively in the courts. While the Act did not directly confer judicial power on non-judicial bodies, the majority found that it created a scheme that, in its practical operation, could be seen as an exercise of judicial power by the executive. Specifically, the power to compel the taking of samples for the purpose of investigating past crimes, without a direct link to a current or imminent judicial proceeding, was considered to be an encroachment on the judicial function. The Court applied the principle that the separation of powers, as embodied in Chapter III, requires that the functions of the judiciary be kept distinct from those of the executive and legislature.

The High Court ordered that the appeal be dismissed, upholding the challenge to the constitutional validity of the *Crimes (Forensic Procedures) Act 2000* (NSW) in its application to Mr Kable.
