Chattaway v Minister for Health (No 2)

The case before the court involved an application for judicial review brought by the applicant against the respondents, who were the Minister for Health and others. The dispute centred on the applicant's challenge to his detention under the Mental Health Act 2009 and the associated administrative decisions. The matter was heard by the Full Court of the Supreme Court of South Australia, which had already answered a question of law in the respondents' favour. The applicant sought to challenge this decision and the associated procedural matters, but the application was ultimately dismissed.

The legal issues before the court included the proper procedure for determining questions of law reserved for the Full Court, the appropriate costs order in the context of a dismissed application, and whether the case had become moot following the applicant's return to Yatala Labour Prison. The court needed to determine whether the application for judicial review should be considered in light of the applicant's return to Yatala, and if so, whether this rendered the matter moot. Additionally, the court had to assess the appropriate costs order given the nature of the proceedings and the applicant's withdrawal of other aspects of the case.

The court found that the respondents were entitled to an award of costs as there was no proper reason why they should not receive compensation for the costs incurred. The Full Court's determination of the question of law was deemed to have re-enlivened the relevant issue, and therefore the case was not moot. The court rejected the applicant's argument that the case had become moot due to his return to Yatala, as the underlying issue of his detention remained relevant. The court concluded that the applicant should pay the respondents' costs on the standard costs basis, to be agreed or taxed.

In conclusion, the court ordered that the applicant pay the respondents their costs incurred in the proceedings. The order was based on the successful determination of the question of law by the Full Court and the dismissal of the application for judicial review. The court did not accept the applicant's argument that the case had become moot, as the issue of his detention remained pertinent. The costs were to be assessed on the standard costs basis, to be agreed or taxed.
