17 And at page 335 Kirby J said:
"The removal of serious and unjustifiable disparities in the treatment of like cases is a legitimate goal of the administration of criminal justice."
35 Whilst the terminology used might be slightly different it is apparent that the judges were of one, or at least of similar, mind. To adopt the terminology of Kirby J, the question raised by the applicant in this case could be posed as whether there is a "serious and unjustifiable disparity" between the treatment of the cases of the applicant and Vulaono.
36 In my view the decision of the sentencing judge to distinguish between the cases of the two offenders on the basis of the significant difference in age was one that was open to her.
37 In R v Rushby [1999] NSWCCA 104 the offenders in question were aged 16 years 3 months and 18 years 10 months. Barr J (at [24]) regarded that difference as "large and significant". In Douglas v R [2006] NSWCCA 94 the offenders were "almost 21" as opposed to 17 years 1 month. Latham J regarded that difference as of "some significance".
38 In R v Mastronardi [2000] NSWCCA 12; (2000) 111 A Crim R 306, the sentencing judge had dealt with a man who was aged 27 at the time of offending as though comparable to a young person. Sully J said:
20 In my opinion, and with respect to his Honour, that assessment was fundamentally misconceived. There was, so far as I can see, no evidence that the respondent was, in a precise sense, mentally deficient or retarded. I do not believe that the evidence shows, in any credibly particular sense, that the respondent was notably immature for his age; but, even if the contrary be accepted, there is a world of difference between the proposition that a 27 year old man is immature, and the proposition that the same man is so emotionally retarded that he is fairly to be regarded as a young person in the sense contemplated by the particular authorities, - GDP (1991) 53 A Crim R 112, and Lattouf ; unreported, 12 December 1996, Court of Criminal Appeal, - to which his Honour expressly refers
39 In the same way there is, in my view, a "world of difference" between a 35-year-old man, albeit one regarded by the sentencing judge as "emotionally immature" and an 18 year old, one who had only just past his 18th birthday and who was described in a Pre Sentence Report as demonstrating "a high degree of naivety". I note that the first of the offences on Vulaono's Form 1 was committed just prior to his 18th birthday. The sentencing judge also expressed the view about his offending conduct as "very much a product of his immaturity". She concluded, as a consequence that she did not consider that "the ordinary principles involved in the sentencing of young people need be put to one side". She had earlier referred to those principles as involving emphasis upon rehabilitation and general deterrence having less significance.
40 The sentences imposed upon both the applicant and the co-offender were lenient. As noted earlier, the sentencing judge found that in the case of the applicant the objective seriousness of the offence was in the "low range". In making that finding she took into account, amongst other things, that the quantity of the drug involved on each occasion was less than the small quantity applicable to the drug cocaine. I should not be taken to suggest that the quantity of drug was irrelevant. However it needs to be borne in mind in relation to the offence of on-going supply of prohibited drugs that the offence was created to more appropriately deal with those involved in persistent drug supply where the actual quantities supplied, often small, were not the true measure of the level of criminality: see, for example, R v Smiroldo [2000] NSWCCA 120; (2000) 112 A Crim R 47; R v Hoon [2000] NSWCCA 137; R v Giang [2005] NSWCCA 387.
41 A noteworthy feature of this case was that whilst the offence in s 25A is made out upon proof of three or more supplies within 30 consecutive days, here there were eight supplies within such a period.
42 Another feature taken into account by the sentencing judge in her assessment of objective seriousness was that the drugs were supplied to an undercover police operative and not disseminated into the community. That is a relevant consideration but it is of minimal significance. The applicant had the intention to supply and did so on the understanding that the drugs would find their way into the community. The fact that they did not was not through his doing: see R v Chan [1999] NSWCCA 103 per Smart AJ at [21], approved in R v Way [2004] NSWCCA 131; (2004) 60 NSWLR 168 at [172].
43 The voluntary cessation of drug supply activity was a factor taken into account in the applicant's favour in the manner earlier referred to. I note, however, that in respect of both offenders the evidence was that the last drug transaction occurred on 26 October 2007. There was no evidence of the commission of any offence by either of them up until the time they were both arrested on 16 January 2008. Be that as it may, I am of the view that it was open to the sentencing judge to distinguish between the two offenders in terms of the length of both the total term and the non-parole periods in the manner in which she did. I am not of the view that there is a "serious and unjustifiable disparity" when regard is had to the legitimate weight given by the sentencing judge to the youthfulness of the co-offender. The voluntary cessation factor in the applicant's favour did not call for a sentence the same as that imposed upon Vulaono, or a sentence that was less than that which was in fact imposed.
44 I would reject Ground 1.
45 I would grant leave to appeal but dismiss the appeal.
