Australian Capital Territory v Lewis

The Australian Capital Territory Court of Appeal heard an appeal from a decision of a single judge of the Supreme Court concerning the administration of a periodic detention sentence. The dispute arose after the respondent failed to perform periodic detention following his release on bail. The primary judge had found that the respondent's sentence of imprisonment had expired and that his periodic detention had ended, orders which the Australian Capital Territory sought to challenge.

The Court of Appeal was required to determine whether the respondent had failed to perform periodic detention for the purposes of s 58(1)(a) of the *Crimes (Sentence Administration) Act 2005* (ACT), as that provision was in force in 2009. It also considered whether grounds for a permanent stay of the respondent's sentence existed and reviewed a discretionary order for costs made by the primary judge.

The Court reasoned that s 58(1)(a) applied to a person who did not report to perform periodic detention when there was an extant legal obligation to do so. This interpretation was derived from the provision itself, read in context, and did not require the addition of qualifying words. The Court noted that s 42(1) of the Act mandates that an offender must serve periodic detention within their designated period, and s 40 defines this period as the originally ordered term or as extended under Chapter 5. The Court contrasted this with a situation where an order for periodic detention is stayed, in which case s 58(1)(a) would not apply because there would be no legal obligation to attend. The appeal was dismissed, and the Australian Capital Territory was ordered to pay the respondent's costs.
