Ground 1 - The difference in the penalty imposed on the co-offender gives rise to a justifiable sense of grievance in the applicant
27 The relevant principle is that set forth in the well known decisions of Lowe v The Queen (1984) 154 CLR 606 and Postiglione v The Queen (1997) 98 A Crim R 134 at 301 and it does not require repetition, for the purpose of determining this application, other than to note that, for the Court to intervene, it must be satisfied that the difference in sentences between co-offenders, after making sufficient allowance for any differences in their objective and subjective circumstances, would leave the applicant with a justifiable sense of grievance.
28 It is to be noted that, when sentencing the applicant, his Honour found that the s 113(2) offence fell "towards the upper end of [the] scale of seriousness". When sentencing Mancic, his Honour described the offence as falling "towards the upper end of the mid-range for such offences". While the difference in categorisation was not explained, it may be that his Honour took into account the dangerous conduct of the applicant as the driver, both while ramming the Subaru into the service station door, and while endeavouring to ensure the escape of Mancic and himself.
29 It was a serious offence of its kind that called for significant weight to be given to the elements of punishment, retribution and deterrence, both specific and general, in the case of each offender. However, in the case of the joint enterprise that was here involved, it is difficult to see why their complicity or objective criminality should not have been regarded as equivalent, particularly as it was Mancic who damaged the protective barrier to the cigarette display, and whose role it clearly had been to steal the property contained therein, which had been the purpose of the ram-raid.
30 There were differences of significance between the two offenders. In favour of the applicant, he was held to have been entitled to a 5% greater discount for the plea, which in his case had been offered earlier. Additionally there was a finding of special circumstances in his case, but not in the case of Mancic. That circumstance explained the numerical similarity in their non-parole periods, but it did not explain the apparent difference in starting points which in the case of the applicant was 7 years, and in the case of Mancic 3 years and 9 months.
31 The remaining circumstances certainly did operate against the applicant, in so far as he had a much worse criminal history than Mancic, who had not previously served any custodial sentence. That offender was aged 25 years at the time of the offence, and had a record that was confined to two offences of break enter and steal, as well as offences of larceny, possess housebreaking implements and assault, each of which had been dealt with by way of a bond.
32 It is well established that the difference between the criminal histories of offenders, and their prior custodial experiences, is a circumstance that may properly justify a difference in sentencing outcomes. As was said in Postiglione at p 303:
"as between co-offenders, different criminal histories and custodial patterns may be such as to justify a real difference in the time each will serve in prison. And, of course, it is necessary when applying the parity principle that like be compared with like. There may be some aspect of one offender's criminal history or custodial situation which has no counterpart in the case of his or her co-accused. If so, it may justify the imposition of a different sentence or the structuring of the sentence in such a way that it results in some difference in the period actually spent in custody."
33 It is the case that while periodic detention is not an entirely soft option, it is nevertheless considerably less arduous than full time custody, since it only requires detention for part of the week and converts to community service before its completion: see R v Hallocoglu (1992) 29 NSWLR 67 and R v Wegener [1999] NSWCCA 405 at para 32. In the instant case, Mancic was eligible for periodic detention, but the applicant was barred from eligibility because of his prior record (s 65A Crimes (Sentencing Procedure) Act). Mancic received the maximum total sentence available for that form of detention, and as I have observed, his non-parole period was maintained at the statutory proportion.
34 It is evident from the reasons for sentence in Mancic's case, that his prior offences, and breach of a bond, were not entirely minimised, in so far as his Honour observed that the prior break enter and steal matters, in particular, did not give him any assistance, and resulted in the court not being able to extend to him any particular leniency.
35 What was persuasive in not imposing a sentence of full time custody, it seems, was the positive evidence that was available which led his Honour to conclude that, in his case, there was "some hope of genuine rehabilitation" and that he had not become "totally inured to a life of crime."
36 In that regard, there was an expert opinion before the court from Dr Roberts, which contained some analysis of the offender's background. He had been born in Australia and came from a family with a Serbian background. His mother had left the family when he was aged seven years and his father had died when he was about 12 years old. He had then remained in the care of his grandparents, who had been unable to adjust to their son's death, and this led to difficulties in the co-offender's relationship with them.
37 Dr Roberts expressed the view that he had developed unresolved psychological issues in relation to grief, the rejection of his mother, and the suicide of a long term friend, which had led to depression, and a slide into substance abuse and criminal activity. The pre-sentence report was noted as "positive", in so far as it suggested that the co-offender had come to understand the need for him to seek ongoing counselling, and had expressed a willingness to address the matters which had led to his drift into offending behaviour.
38 The difference in sentences was explained by his Honour as referable to the present applicant's criminal history which was described as "much worse" than that of the co-offender. His Honour said, when sentencing Mancic:
"I have come to the conclusion that bearing in mind your relatively short criminal history and the genuine prospects of rehabilitation, the appropriate penalty in this case, particularly as it will be your first custodial sentence, is a sentence of imprisonment to be served by way of periodic detention."
39 In circumstances where there were such marked differences in the criminal histories of the two offenders, and where one offender, the applicant, had in the past displayed a defiance of the criminal law, and an unpreparedness to respect the constraints of parole, and where the other offender was facing a first time of imprisonment, there clearly was a proper basis for the imposition of a heavier sentence upon the applicant. As this Court made clear in R v Lovelock (1988) 19 ALR 327, differences in sentences are justified by differences in antecedents alone.
40 The fact that the applicant had two offences taken into account on a Form 1 that had not been taken into account in relation to the co-offender, was a further ground for differentiation.
41 The question which arises however, is whether the extent of differentiation was so significant as to leave the applicant with a justifiable sense of grievance.
42 In my view this question should be answered in the affirmative. It would appear that his Honour fell into error in his assessment of the culpability of the two offenders, in so far as he categorised the subject offence at a different level of seriousness in the separate reasons for sentence. Additionally the difference between the head sentences and the circumstances in which they were to be served seems to me to have been disproportionate to the differences in their objective and subjective circumstances.
43 I would accordingly grant leave to appeal
