Chattaway v Minister for Health and Wellbeing

This case concerned a question of law reserved for the Full Court of the Supreme Court of South Australia, brought by the applicant, Chattaway, against the Minister for Health and Wellbeing. The dispute centred on the proper construction of section 269V(2)(b) of the *Criminal Law Consolidation Act 1935* (SA) (CLCA), which relates to the detention of defendants. The court was asked to determine whether the phrase "there is no practicable alternative" in that section required the existence of an objective fact, the opinion of the Minister or delegate, or some other matter.

The legal issues before the court were twofold. Firstly, it had to construe section 269V(2)(b) of the CLCA to ascertain the nature of the condition precedent to the Minister's power to direct that a defendant be kept in custody in a prison. Secondly, the court was required to determine the scope of judicial review in relation to such a direction, specifically whether the court's role was limited to assessing the reasonableness of the Minister's delegate's opinion or extended to a broader merits review of the factual circumstances.

The court held that the phrase "there is no practicable alternative" in section 269V(2)(b) requires the opinion or satisfaction of the Minister or their delegate. This opinion must be formed reasonably upon the material before the delegate. The court reasoned that while the phrase implies a factual assessment of feasibility, the nature of the judgment involved—considering resources, costs, personnel, training, treatment, and accommodation, as well as the needs of all detainees—suggested a legislative intention for this complex evaluative judgment to be made by the executive. The court concluded that its jurisdiction in reviewing such a direction was limited to ascertaining whether the delegate held the requisite opinion and whether that opinion was formed reasonably on the available material, rather than undertaking a full merits review.

The court answered the questions of law reserved as follows: the phrase "there is no practicable alternative" does not require the existence of an objective fact, but rather the opinion or satisfaction of the Minister or delegate, and that this opinion must have been formed reasonably upon the material before him.
