12 His Honour accepted that the Respondent was entitled to have taken into account, in his favour, his preparedness to supply information to the police about Cornett and to give evidence in any prosecution of him. He also found that he was entitled to a discount of 25%, for his plea which was to be regarded as having been made at the earliest available opportunity.
13 Attention was given to the provisions of s 21A of the Crimes (Sentencing Procedure) Act, in so far as his Honour identified, as aggravating factors, the matters referred to in s 21A(2)(d), (j) and (n) and correctly excluded those factors that were elements of the offence. The mitigating factors which his Honour found to be present were those mentioned in s 21A(3)(d), (i), (k), and (m). So far as I can see no relevant mitigating factor was overlooked.
14 The Form 1 matters were held by his Honour to have been so highly connected with the commission of the offence that they should not result in any lengthening of the overall sentence either as to the non-parole period or the balance of parole. No error exists in that respect.
15 Special circumstances were found relating to the Respondent's age and the need for an extended period of supervision by reason of the length of the time that he has spent in prison, almost continually, since the age of 22, and his tendency to revert to drug addition. As a result the balance of the term of the sentence was well in excess of that specified in s 44(2) of the Crimes (Sentencing Procedure) Act.
16 It is not evident, on the face of his Honour's comprehensive reasons for sentence that, save for one matter, any relevant sentencing principle was overlooked or incorrectly stated. The only exception was the assumption that the case fell directly within the net of s 54B of the Crimes (Sentencing Procedure) Act. More correctly, since it was a matter dealt with on a plea, the standard non-parole period referred to in the Table provides a reference point: see R v Davies (Supra).
17 In these circumstances the Crown needs to show that the sentence was so obviously outside the legitimate sentencing range as to demonstrate latent error.
18 In my opinion it has satisfied that test for two reasons.
19 The first reason is that the imposition of a sentence involving a non-parole period of 3 years, and a balance of term of 3 years, appears quite disproportionate for an offence which his Honour described as falling towards the "upper end of the scale" for an offence of its kind, even after making full allowance for the subjective circumstances as they were presented to his Honour. In that regard, I would accept the Respondent's contention that his Honour needed to take into account the fact of protection upon the basis of the evidence that was led, being confined to that which came from the Respondent, to the effect that, at the Parklea Correctional Centre, he was only allowed one hour out of the cells each day.
20 I do not, however, consider it necessary to decide the issue which arose, as to whether, in the absence of the Prosecution having placed before the sentencing judge the full factual details of the Respondent's prior conviction for armed robbery, which had been the subject of the decision of this Court in R v Ceissman [2000] NSWCCA 274, it is permissible for us now to have regard to the contents of that judgment, as a curial document on the public record, in determining the adequacy of the sentence. That it was permissible for us to do so, and as a consequence, to be aware of the fact that the Respondent had previously been convicted of an almost identical offence, and then to take that into account when considering whether there was latent error, was the contention of the Crown. Reliance was placed upon R v Snider [2004] NSWCCA 134 per Kirby J at paras 47 to 49, where his Honour, while offering some support for such proposition, considered it unnecessary for decision upon the facts of that case.
21 I similarly consider, in the present case, that there was sufficient on the face of the record, including the finding that the Respondent had "convictions for like offences", and his criminal history, to show that the sentence was disproportionate to the criminality involved, without resort to the earlier judgment of this Court, bearing in mind that the maximum sentence available for the offence was one of imprisonment for 20 years, and that it was one which had been selected by the legislature as appropriate for the specification of a standard non-parole period.
22 In this regard, the statement of principle by Howie J in R v Moon (2000) 117 A Crim R 497 is apposite:
"67 Firstly, the court must have regard to the maximum penalty for the offence at the time when the crime was committed. This will indicate the policy of the legislature at the time the offence was committed: Oliver (1980) 7 A Crim R 174. It will prescribe the limit of the court's discretion, as the maximum penalty is intended for cases falling within the worst category of cases for which the penalty is prescribed: Veen v The Queen (No 2) (1988) 164 CLR 465 at 478; Ibbs v The Queen (1987) 163 CLR 447 at 451. Prima facie the maximum penalty indicates the seriousness of the offence: Gilson v The Queen (1991) 172 CLR 353 at 364.
68 Secondly, the court must consider where in the range of the conduct covered by the statutory offence, the particular criminal conduct committed by the offender falls: Baumer v The Queen (1988) 166 CLR 51 at 57; Ibbs , above, at 452. This will generally indicate the appropriate range of sentences available which will reflect the objective seriousness of the offence committed and set the limits within which a sentence proportional to the criminality of the offender will lie.
…
70 The nature of the criminal conduct proscribed by an offence and the maximum penalty applicable to the offence are crucially important factors in the synthesis which leads to the determination of the sentence to be imposed upon the particular offender for the particular crime committed. Even after taking into account the subjective features of the offender and all the other matters relevant to sentencing, such as individual and general deterrence, the sentence imposed should reflect the objective seriousness of the offence: Dodd (1991) 57 A Crim R 549, and be proportional to the criminality involved in the offence committed: Veen v The Queen (1979) 143 CLR 458. Whether the sentence to be imposed meets these criteria will be determined principally by a consideration of the nature of the criminal conduct as viewed against the maximum penalty prescribed for the offence."
