Attorney-General (Qld) v Lawrence

In the case of Attorney-General (Qld) v Lawrence, the court examined the constitutional validity of the Dangerous Prisoners (Sexual Offenders) Act 2003 (Qld) and the Criminal Law Amendment (Public Interest Declarations) Amendment Act 2013 (Qld) following an application by the Attorney-General for a review of the continuing detention of the respondent. The respondent argued that the amendments made by the Declarations Act infringed the Kable doctrine, which holds that State legislation which affects the exercise of judicial power cannot impair the institutional integrity of the court. The Attorney-General contended that the Court should not exercise jurisdiction as the answers to the questions would not quell any controversy about any “immediate right, duty or liability” of the respondent.

The court considered whether the respondent had a “sufficient material interest” which would be prejudiced by the operation of the Declarations Act and whether the Court should adjudicate upon the questions stated. The court also examined whether the enactment of the Declarations Act invalidated the DPSOA or parts thereof, and whether the Declarations Act effects the fact and appearance of the independence and impartiality of the Supreme Court. The court concluded that the DPSOA is not invalid as a consequence of the enactment of the Declarations Act. However, sections 3 and 6 of the Declarations Act are invalid in that they would have the consequence that the DPSOA now requires the Supreme Court to exercise powers repugnant to or incompatible with the institutional integrity of the Supreme Court, contrary to its function as a Court which exercises judicial power pursuant to Chapter III of the Commonwealth Constitution.

The court's reasoning was that the amendments made by the Declarations Act have the consequence that the DPSOA now requires the Supreme Court to exercise powers repugnant to or incompatible with the institutional integrity of the Supreme Court, contrary to its function as a Court which exercises judicial power pursuant to Chapter III of the Commonwealth Constitution. The court held that the effect of the Declarations Act is to allow the executive to undermine the authority of orders of the Supreme Court under the DPSOA otherwise than by appeal to the Court of Appeal or the High Court. The court found that the Declarations Act is repugnant to or incompatible with the institutional integrity of the Supreme Court as a repository of federal judicial power. Therefore, the court declared sections 3 and 6 of the Declarations Act to be invalid.
