Attorney-General for the State of Queensland v Banwell

The Supreme Court of Queensland was tasked with reviewing a continuing detention order for the respondent, Banwell, who has a history of sexual offending. The Attorney-General for the State of Queensland sought to affirm the order, which was made on 18 December 2019, under the Dangerous Prisoners (Sexual Offenders) Act 2003 (Qld). The Court was required to determine if Banwell remained a serious danger to the community and if there was an unacceptable risk of him committing a serious sexual offence if released from custody. The review also considered whether a supervision order could adequately manage the risk posed by Banwell.

The legal issues before the Court included assessing the evidence presented regarding Banwell’s dangerousness, his diagnosis of psychopathy, anti-social personality disorder, borderline intellectual function, and frontal lobe disorder, and the effectiveness of potential supervision orders. The Court had to weigh the risk to the community against the principles of proportionality and human rights, particularly the right to liberty and security of the person.

The Court concluded that Banwell continued to pose a serious danger to the community, affirming the continuing detention order. It was determined that there was an unacceptable risk that Banwell would reoffend if released without appropriate supervision. The Court found that a supervision order was not sufficient to manage the risks effectively, given the severity and nature of Banwell’s past offences and his diagnosed conditions. Therefore, the Court decided to maintain the continuing detention order to ensure adequate protection of the community.

In summary, the Court upheld the decision to keep Banwell detained under the continuing detention order, ensuring his continued incarceration as a measure to protect the community from the risk he poses.
