The State of Western Australia v Decke [No 6]

The State of Western Australia brought an application for the review of a continuing detention order in relation to Decke, pursuant to the Dangerous Sexual Offenders Act 2006 (WA). Decke, a convicted sex offender, challenged the validity of the continuing detention order, arguing that it was unlawful and that the provisions of the Act were unconstitutional. The matter was heard in the Supreme Court of Western Australia.

The court was required to determine whether Decke's continuing detention order was valid under the Dangerous Sexual Offenders Act 2006 (WA), and whether certain provisions of the Act were consistent with the Constitution of Australia. Specifically, the court had to assess whether the statutory provisions that allowed for the detention of Decke without a hearing were in breach of his rights under the Constitution, including the right to freedom from arbitrary detention and the right to a fair hearing.

The Supreme Court of Western Australia held that the continuing detention order was valid and that the provisions of the Act were consistent with the Constitution. The court found that the legislative scheme provided for a fair and proportionate response to the risk posed by Decke as a dangerous sexual offender, and that the provisions of the Act did not breach the Constitution. The court rejected Decke's argument that the provisions were arbitrary and unconstitutional, holding that they were necessary and appropriate in the circumstances.

The Supreme Court of Western Australia dismissed Decke's application for the review of his continuing detention order. The court found that the provisions of the Dangerous Sexual Offenders Act 2006 (WA) were valid and that Decke's detention order was consistent with the Constitution. The court held that the legislative scheme provided for a fair and proportionate response to the risk posed by Decke as a dangerous sexual offender.
