The power of the Sentence Administration Board to cancel periodic detention under the Crimes (Sentence Administration) Act 2005 (ACT) is not an exercise of judicial power and does not impair the institutional integrity of the ACT Supreme Court. The exercise of judicial power is complete upon sentencing; the administration of the manner in which a sentence is served is an executive function. The Kable doctrine does not extend to invalidate laws that confer power away from courts onto executive bodies, at least where the conferral does not involve government interference with judicial orders. The current state of authority does not support the proposition that Chapter III separation of powers applies to the ACT as a self-governing territory.
