35 It is also important to note that the sentence the subject of review in Clare was passed in accordance with the Parole of Prisoners Act 1966 where the ratio of head sentence to non-parole period were not prescribed as is the case under the current sentencing legislation. That Act was repealed by the Probation and Parole Act 1983 which commenced on 27 February 1984. No statutory ratio between head sentence and non-parole period was provided for under that Act. Each of the offences that the applicant pleaded guilty to occurred after that date. The Probation and Parole Act was repealed by the Sentencing Act 1989 which commenced on 25 September of that year. It was later repealed and replaced by the present Act. The Sentencing Act introduced a statutory proportion between head sentence and non-parole period for the first time subject to a finding of special circumstances. The applicant's offences straddle both the Probation and Parole Act and the Sentencing Act, in that counts 4 and 5 allege an indecent assault against SK which occurred between the 2 January 1988 and 31 December 1989 and a sexual assault committed against her between the same dates. Whether or not the offences constituted by counts 4 and 5 were subject to the Sentencing Act or the Probation and Parole Act is, however, entirely a matter of conjecture. In any event, her Honour found special circumstances established in the applicant's case and varied the statutory ratio for each of the individual offences to a range between 50 and 60 per cent. Even if the Probation and Parole Act was the sentencing legislation in operation, the ratio between head sentence and non-parole period fixed by her Honour was commensurate with what Howie J noted in AJB v R [2007] NSWCCA 51; 169 A Crim R 32 at [39] to be the fixing of a non-parole period between a half and a third of the term of the sentence under the Probation and Parole Act.
36 The other cases to which the applicant referred her Honour, and to which reference was made on the appeal, are for other reasons in my view wholly distinguishable.
37 In Ibbs v The Queen (1987) 163 CLR 447, the High Court granted special leave to appeal against a sentence imposed on an appellant who was convicted of what was then the relatively new offence of sexual penetration without consent under s 324D of the Criminal Code of Western Australia. The complainant was an adult woman who had been invited by the appellant's wife to have sexual intercourse with her husband. She participated in consensual sexual intercourse with the appellant on multiple occasions prior to the occasion giving rise to the offence. On that occasion she withdrew her consent to intercourse after it had commenced consensually. On conviction a sentence of 4 years imprisonment was imposed. The High Court intervened on the basis of what was said to be a demonstrated and gross violation of the principles which ought to guide a sentencing discretion where in the particular circumstances of that case the complainant had consented, or was honestly or reasonably believed by the appellant to have consented to the act of penetration by which intercourse was commenced but where consent was withdrawn in the course of that sexual act.
38 In R v Jordan [1983] NSWCCA 254, sentences were also imposed under the Parole of Prisoners Act on three counts of indecent assault on a female under 16 pursuant to s 76 of the Crimes Act (now repealed). That offence carried a statutory maximum of 6 years and is in like term to the six counts on the subject indictment charging an indecent assault contrary to s 61E(1)(A) of the Crimes Act. An aggregate of 8 years imprisonment was imposed with a non-parole period of 4 years. The Court was of the view that a sentence of 8 years against a statutory maximum of 6 years for each offence was excessive despite the Court confirming that partial accumulation across the body of offending was appropriate. In so far as the non-parole period was concerned, the Court considered that the applicant's extremely favourable rehabilitative prospects, in particular the success the applicant had demonstrated in dealing with an alcohol addiction, justified a 2 year non-parole period.
39 The case of R v Lyne [1982] NSWCCA 84 also involved an adult victim. The Crown appealed against the inadequacy of a 3 year good behaviour bond imposed on an offender who picked up a hitchhiker, overpowered her and sexually assaulted her. The appeal was allowed and the offender was sentenced to 2 years imprisonment with a non-parole period of 6 months. Not only was the sentence imposed following a successful Crown appeal, the case is wholly distinguishable and gives no indication at all as to any relevant sentencing pattern in respect of the offences for which this applicant pleaded guilty.
40 Against the number of cases and their marked dissimilarity both from each other and the applicant's case, it is hardly surprising that her Honour was unable to discern any reliable sentencing pattern that was current at the time of the applicant's offending in respect of the offences which were under consideration.
41 By analogy with Featherstone v R [2008] NSWCCA 71 the applicant sought to argue that a modest sample of cases of what was submitted were broadly similar sexual offences to those in the present case ought to have attracted a similar outcome. In Featherstone the Court was satisfied that despite the review of a small sample of cases there was a sufficient similarity between the offences to which those cases referred and the case under consideration to support the proposition that there has been a significant upward trend in the length of sentences for offences of that particular character in recent years. It was an impression that Bell JA held accorded with her recollection of the pattern of sentences for sexual offences before the introduction of the Sentencing Act. On the basis of both impression and recollection, her Honour considered that error had been demonstrated in the sentences imposed at first instance.
42 Featherstone is not authority for the proposition that whenever a small number of cases are presented a sentencing judge should be able to discern a sentencing pattern. To the contrary. It is simply a statement by the Court that on that particular occasion, and having regard to the information placed before it, a pattern could be discerned. As I have sought to make clear I do not regard it as open to the sentencing judge in the present case to have discerned a pattern from the very limited number and wholly dissimilar range of cases placed before her.
43 In the absence of statistical and non-statistical data her Honour was obliged to adopt the approach which was settled in R v MJR [2002] NSWCCA 129; 54 NSWLR 368. Her Honour was provided with MJR together with a case note of AJB v R [2007] NSWCCA 51; 169 A Crim R 32 which both confirmed the correctness of that approach and developed it.
44 In both AJB and MJR particular attention was directed to the proper approach to the specification of the non-parole period in cases where the offences were committed prior to the introduction of the Sentencing Act. As Howie J observed in AJB, a non-parole period under the Probation and Parole Act was usually somewhere between a third and a half of the length of the sentence, which might itself be a practice that is sufficient to constitute special circumstances justifying departure from the statutory ratio fixed under the present regime. As his Honour said at [37], this Court "should endeavour to apply the practice that existed in 1982 in specifying a non-parole period because that practice would favour the applicant".
