Director of Public Prosecutions v Ahwan

The Director of Public Prosecutions (DPP) appealed to the Supreme Court of the Northern Territory against a decision of the Supreme Court which dismissed an application to increase the non-parole period for a prisoner convicted of murder. The prisoner had been convicted in 1990 and sentenced to life imprisonment. The dispute centred on the interpretation of section 19(3)(b) of the Sentencing (Crime of Murder) and Parole Reform Act 2003 (NT), which mandates a 25-year non-parole period if the murder was part of a course of conduct that included an act or omission, before or after the victim's death, that would have constituted a sexual offence against the victim.

The legal issue before the Court of Criminal Appeal was whether the prisoner's conduct, specifically the penetration of the deceased victim's vagina with a broom handle after her death, constituted a "sexual offence" for the purposes of section 19(3)(b) of the Act. The trial judge had found that the penetration occurred post-mortem and concluded that this conduct, in the absence of the victim being alive, did not amount to a sexual offence as defined by the relevant legislation. The DPP contended that the trial judge erred in this interpretation, arguing that the legislative intent, particularly as evidenced by the Second Reading Speech, was to capture such post-mortem sexual degradation within the ambit of the provision.

The Court of Criminal Appeal, in allowing the appeal, reasoned that while courts must interpret legislation according to its plain words, the context and purpose of the Act were paramount. The Court noted that the Sentencing (Crime of Murder) and Parole Reform Act 2003 was beneficial legislation designed to allow for parole for those serving life sentences for murder, with a longer non-parole period for murders accompanied by sexual offending. The Court found that the phrase "would have constituted a sexual offence" was intended to relate the conduct to the definition of a sexual offence, even if the victim was deceased at the time. The Court considered that the inclusion of offences like those under sections 125B and 125C of the Criminal Code in Schedule 3 of the Sentencing Act, which could be committed in relation to a deceased person, demonstrated that the legislature contemplated post-mortem conduct. The Court concluded that the plain meaning of the words, when read in light of the legislative purpose, supported the DPP's submission that the prisoner's conduct attracted the 25-year non-parole period.

Consequently, the Court of Criminal Appeal allowed the appeal, revoked the existing non-parole period, and fixed a non-parole period of 25 years for the respondent's sentence of life imprisonment.
