19 It is the case that his Honour did not, in this passage or elsewhere, make any express reference to s 44 or to s 45 of the Crimes (Sentencing Procedure) Act 1999 as those provisions existed before their repeal and replacement, or to the fact that he had considered, but had declined to fix, a non-parole period. It is possible that, in the passage last cited, he had these provisions implicitly in mind, but if so it would have obviously been preferable for clear and express reference to be made to them.
20 It is this circumstance that gives rise to the present application, it being submitted that his Honour erred in not fixing a non-parole period in compliance with s 44(1) and (2) of the Act, and in failing to give reasons for not doing so, as required by s 45(2) of the Act, as those provisions then applied to this case.
21 These legislative requirements are important, as emerges from the decision of this Court in R v Parsons and Poore [2002] NSWCCA 296 per Smart AJ, with whom Handley JA and Sully J agreed at para 100, although, as the two sections expressly provide, non-compliance does not invalidate the sentence.
22 The sentencing judge in this case, it seems to me, did not follow the procedure, which it has been accepted as appropriate, in cases where an order is ultimately made that involves an alternative to full-time custody. Clear guidance is provided in this respect by the decisions in R v Wegener [1999] NSWCCA 405; R v Hanslow [2002] NSWCCA 161; R v Eagleton [2003] NSWCCA 40 and R v Schodle [2003] NSWCCA 164, which emphasise the need for a two step approach.
23 The sentencing judge is expected first to fix an appropriate period of imprisonment, and is then required to consider whether it should be served in circumstances other than full-time custody. Those considerations or issues are not to be telescoped, and in particular it is inappropriate to compensate for the leniency, which is involved in periodic detention, by extending the term of imprisonment which is to be served in this way.
24 In the present case his Honour seems not to have approached the case in that way. Having noted the sentences imposed upon the co-offenders he then determined the sentence which he should pass by reference, it would seem, solely to the question of parity.
25 Properly approached, his Honour should have determined what was an appropriate period of imprisonment, to reflect the applicant's objective criminality and his subjective circumstances, and then to have paid regard to the question whether the case was suitable for periodic detention. It was, at that point, that the consideration of parity would properly have entered the deliberations, in the way explained in Lowe v The Queen (1984) 154 CLR 606 and Postiglione v The Queen (1997)189 CLR 295, so as to ensure there was no marked disparity between the offenders, such as to give rise to a justifiable sense of grievance.
26 The principle of parity is, of course, concerned with offenders who have committed essentially the same crime and who are in that sense properly to be considered as co-offenders. In the present case, the offences were similar, and they broadly fell within an enterprise in which each offender was involved, however, they were involved in different ways, and as a consequence it did not involve strictly a common offence.
27 In those circumstances, while parity remained relevant in a general sense, so far as it involves the principle of due proportion between offenders, it did not have quite the same relevance or force as it might had each offender been sentenced for the same offence.
28 Particularly is that so when it is appreciated that the objective criminality of Karnib was obviously greater than that of the applicant.
29 For these reasons, I am of the view that, as a matter of principle, his Honour erred in the approach which was taken. It does not, however, necessarily follow that this Court should intervene, since the applicant must still persuade it that some lesser sentence involving the setting, in this case, of a non-parole period was warranted in law and should have been passed - s 6(3) Criminal Appeal Act 1912.
30 In my view a head sentence of three years to be served by way of periodic detention for the present offence was appropriate having regard to the calculated criminality of the applicant, his prior record and the fact that he had reoffended while subject to a bond for an offence of dishonesty. He was, however, entitled to the benefit of his plea and to the positive steps which he had taken and which appeared to his Honour to have demonstrated a commitment to his rehabilitation.
31 These circumstances lead me to the view that a non-parole period should have been set. That non-parole period in my view should have been one equivalent to 75 per cent of the head sentence.
32 I am not persuaded that special circumstances have been shown that would warrant any further reduction or variation in that ratio. Nor do I believe, having regard to the head sentence which should remain unaltered, and a weighing of the respective criminality of Karnib and Senior in their associated offences, that any legitimate sense of grievance could be occasioned, on their part, by extending to the applicant the opportunity of release on parole.
33 I would propose the following orders:
