Director of Public Prosecutions for Western Australia v Brown [No 2]

The case involved the Director of Public Prosecutions for Western Australia bringing a review of a detention order against the respondent, Brown. The dispute centered around the annual review of Brown's detention under the Sex Offenders Act 2009 (WA). The Supreme Court of Western Australia was tasked with interpreting the legislative provisions governing the timing and frequency of these reviews, specifically focusing on the interpretation of the relevant sections of the Act and the commencement date for calculating the review period.

The primary legal issue before the court was the interpretation of the relevant statutory provisions concerning the timing of the annual review of Brown's detention. The court had to determine whether the annual review was to be conducted on the anniversary of the commencement of the detention order or on the anniversary of the date on which the order was last reviewed. Another issue was the commencement date for calculating the review period, whether it should be the date of the initial detention order or the date of the last review. The court was also required to consider the appropriate orders that could be made to address the issue of the overdue review and whether these orders could be made nunc pro tunc.

In its decision, the court found that the annual review of Brown's detention should occur on the anniversary of the commencement of the detention order, not the last review. It interpreted the relevant statutory provisions to mean that the review period should begin from the date of the initial detention order. The court held that the statutory scheme aimed to ensure that the detention order is reviewed annually and that the review date should not be dependent on the timing of the previous review. The court also found that orders could be made nunc pro tunc to address the overdue review, and that such orders would not contravene the finality principle, as they would not alter the substantive outcome of the detention order but merely correct the procedural error. The court provided directions for the forthcoming review hearing, including the due date for the annual review.

The final orders of the court declared that the annual review of Brown's detention should occur on the anniversary of the commencement of the detention order. It also declared that the review period should commence from the date of the initial detention order. The court made orders nunc pro tunc to address the overdue review, ensuring that the review would be conducted in accordance with the statutory provisions. The court provided clear directions for the forthcoming review hearing, including the due date for the annual review.
