31 In R v Zamagias [2002] NSWCCA 17 Howie J, with whom Hodgson JA and Levine J agreed, stipulated the steps to be taken by a Court when sentencing an offender to a term of imprisonment and then determining to suspend its execution pursuant to s 12 of the Crimes (Sentencing Procedure) Act. First, the Court is to determine whether a full-time custodial sentence is called for in accordance with s 5 of the Crimes (Sentencing Procedure) Act. Next, the Court must determine the length of any such sentence without regard to how the sentence will be served and only then to determine how the sentence should be served having regard to the statutory alternatives to full time custody and their availability. As Howie J made explicit in Zamagias:
"…the appropriateness of an alternative to full-time custody will depend upon a number of factors, one of importance being whether such an alternative would result in a sentence that reflects the objective seriousness of the offence and fulfils the manifold purposes of punishment".
32 While a failure to expressly articulate the taking of these steps would not necessarily compel the conclusion that there was a failure to properly carry out the sentencing exercise, the process of reasoning should reveal an appreciation of the gradated alternatives to full time custody and why a suspended sentence, as the most lenient option, is the appropriate order in the particular circumstances of the case. In the absence of reasoning of this kind the sentencing exercise is susceptible to challenge and may, as in this case, give rise to a Crown appeal.
