Abbott v Commissioner of Police

In Abbott v Commissioner of Police, the applicant, who had escaped legal custody in Western Australia in 1989, was eventually imprisoned in Queensland and released on parole in 2016. Following his release, an application was made to execute a warrant issued under the Justices Act 1902 (WA) and return him to Western Australia. The applicant sought a review of the magistrate's decision to extradite him to Western Australia, arguing that it was an abuse of process to be extradited to serve the balance of an old sentence and face further charges, given that the Attorney-General of Western Australia had previously refused to agree to his transfer. The applicant contended that sections 83 and 86 of the relevant legislation, which do not provide for abuse of process as a ground for refusing extradition, were invalid as they required a court to act inconsistently with its essential character by excluding the inherent power to dismiss proceedings for abuse of process.

The legal issues before the court were whether sections 83 and 86 of the relevant legislation excluded abuse of process as a ground for refusal of extradition, and whether these sections, by excluding the inherent power of the court to dismiss proceedings for abuse of process, were invalid because they required a court to act in a way inconsistent with its essential character. The court examined the nature of the powers conferred by sections 83 and 86, with the magistrate exercising an administrative power and the Supreme Court exercising a judicial power, both concerned solely with whether the applicant was liable to be extradited on a valid warrant, not with the extraditing State’s criminal law or the applicant’s guilt or innocence.

The court held that the power conferred on the magistrate by section 83 was administrative and the power conferred on the Supreme Court by section 86 was judicial. Both powers were concerned only with whether the applicant was liable to be extradited on a valid warrant, not with the extraditing State’s criminal law or with determining the applicant’s guilt or innocence. The court found that the magistrate and the Supreme Court were not required to consider whether the applicant’s extradition would result in an abuse of process, and therefore sections 83 and 86 did not exclude abuse of process as a ground for refusal of extradition. The court also held that the sections did not require a court to act inconsistently with its essential character by excluding the inherent power to dismiss proceedings for abuse of process. The application for review was dismissed, and the applicant was to be returned to Western Australia within seven business days.
