"[76] Whatever the theoretical and practical objections, suspended imprisonment is both a popular and much used sentencing option in Australia. Courts may not ignore the provision of this option because of defects occasionally involved in its use. Nonetheless, the criticisms draw attention to the need for courts to attend to the precise terms in which the option of suspended sentences of imprisonment is afforded to them and to avoid any temptation to misapply the option where a non-custodial sentence would suffice. They also emphasise the need to keep separate the two components of such a sentence, namely the imposition of a term of imprisonment, and the suspension of it where that is legally and factually justified.
[79] The common failure of parliaments to state expressly the criteria for the suspension of a term of imprisonment has led to attempts by the courts to explain the considerations to which weight should be given and the approach that should be adopted. The starting point, given emphasis by the terms of s 76(2), is the need to recognise that two distinct steps are involved. The first is the primary determination that a sentence of imprisonment, and not some lesser sentence, is called for. The second is the determination that such term of imprisonment should be suspended for a period set by the court. The two steps should not be elided. Unless the first is taken, the second does not arise. It follows that imposition of a suspended term of imprisonment should not be imposed as a "soft option" when the court with the responsibility of sentencing is "not quite certain what to do".
[80] The question of what factors will determine whether a suspended sentence will be imposed, once it is decided that a term of imprisonment is appropriate, is presented starkly because, in cases where the suspended sentence is served completely, without reoffending, the result will be that the offender incurs no custodial punishment, indeed no actual coercive punishment beyond the public entry of conviction and the sentence with its attendant risks. Courts repeatedly assert that the sentence of suspended imprisonment is the penultimate penalty known to the law and this statement is given credence by the terms and structure of the statute. However, in practice, it is not always viewed that way by the public, by victims of criminal wrong-doing or even by offenders themselves. This disparity of attitudes illustrates the tension that exists between the component parts of this sentencing option: the decision to imprison and the decision to suspend.
[81] A number of attempts have been made to resolve this tension and to provide guidance concerning the circumstances in which a sentence of imprisonment should be suspended. There is a line of authority in Australian courts that suggests that the primary consideration will be the effect such an order will have on rehabilitation of the offender, which will achieve the protection of the community which the sentence of imprisonment itself is designed to attain. But most such statements are qualified by judicial recognition that other factors may be taken into account. The point is therefore largely one of emphasis.
[84] In my view, to limit the exercise of the discretion to suspend a sentence of imprisonment by reference wholly, mainly or specially, to the effect which suspension would have on rehabilitation of the offender would constitute an error. There is nothing in the grant of the power, as expressed in the applicable legislation, to justify confining its availability in such a way. Had the legislature intended to limit the discretion to suspend by reference to such a consideration, it could have done so. This consideration is particularly relevant to the Western Australian legislation, which amounts to a recent endeavour to collect all the main principles of sentencing in a statute of general application.
[85] Moreover, the scheme of the legislation, and the two steps which s 76(1) and (2) of the Act requires, suggest, as a matter of construction, that the same considerations that are relevant for the imposition of the term of imprisonment must be revisited in determining whether to suspend that term. This means that it is necessary to look again at all the matters relevant to the circumstances of the offence as well as those personal to the offender. It would be surprising if the legislation were to warrant, at the second step, concentration of attention only on matters relevant to the offender, such as issues of the offender's rehabilitation and the court's mercy. On the contrary, the structure and language of s 76(2) of the Act support the view that what is required by a proposal that a term of imprisonment should be suspended is reconsideration of "all the circumstances". This necessitates the attribution of "double weight" to all of the factors relevant both to the offence and to the offender - whether aggravating or mitigating - which may influence the decision whether to suspend the term of imprisonment.
[86] Adopting this approach, then, permits attention to be given not only to the circumstances personal to the offender but also to the objective features of the offence."
