15 Plainly, an offender who has given assistance to the prosecuting authorities is entitled to be considered leniently. The policy is embodied in the sentencing principle stated in s.16A(2)(h) of the Sentencing Act 1991.[10] It is in the public interest that thieves and other offenders be encouraged to fall out and so facilitate the exposure and prosecution of criminals who might otherwise go undetected or unpunished. Leniency in sentencing is calculated to have that effect. Furthermore, to adopt Callaway, J.A.'s reasoning in R. v. Duncan[11] and to adapt it to the sorts of discounts that are to be allowed for cooperation with the police and the prosecution, in a time of rising sentences the discount should be more, rather than less.
16 No doubt cooperation does not necessarily lead to the sort of discount of up to fifty percent that may sometimes apply in drug and other cases where an offender's assistance is of special significance or comes at very great risk to himself or herself, or where for some other reason such massive leniency is warranted. As Callaway, J.A. also said in R. v. Duncan,[12] in each case it is a matter of exercising a wide discretion according to the facts and circumstances of the case. In this case the task called for an informed consideration of the matters mentioned by the Crown and an intuitive assessment of the discounts which should be applied.[13]
17 Given the very considerable experience of the sentencing judge, it might have been assumed that his Honour would have approached the matter on that basis. But, with all respect, I find it hard to see that a discount of only one year in a case of this kind provides adequate reward for the sort of cooperation that was offered. Despite the fact that ultimately the appellant did not give evidence against the co-accused, the judge was not aware that that would be so, nor was he aware that CD would not be tried for arson. Equally, his Honour could not have known that she would plead guilty to other offences. It was also said at the plea hearing that but for the appellant's undertaking to give evidence, the prosecution of CD would be very difficult, and perhaps impossible with respect to the count of arson. Inasmuch as the judge approached the matter on the basis that the appellant's offending was necessarily more serious than that of CD, I also consider that the appellant's counsel is correct that his Honour's determination of the appropriate level of discount was to that extent informed by error.
18 Given my conclusion that ground 2 is made out, it is perhaps unnecessary to reach a concluded view on ground 3, but I should say that as at present advised I consider that a discount of only one year did not sufficiently reflect the level of discount which was warranted in the circumstances of this case.
Ground 1 - manifest excessiveness
19 In light of what I have said about grounds 2 and 3, it is unnecessary to reach a concluded view about the ground of manifest excessiveness.
Resentencing
20 The sentencing discretion having miscarried, it falls now to this Court to re-sentence the appellant afresh.
21 I start with the fact that although the appellant was induced by CD to commit the offences, and so far as I can see she was principally responsible, the nature and gravity of the appellant's offending must still be regarded as being of a serious order. As the evidence disclosed, the offending was not altogether spontaneous, but to some degree premeditated in the sense that the determination to undertake it evolved over a period of time in response to the blandishments of CD. The offences were also to some extent motivated by greed, in that the appellant intended always to have his share of what he believed would be between $5,000 and $7,000 to be found on the premises. As well as that, the appellant admitted under cross-examination that he understood what he was doing and that he understood it would have serious consequences, and, as the Crown points out, he also had the clarity of mind to secure what he thought to be his rightful share of the proceeds and to destroy incriminating evidence very shortly after leaving the scene of the crime. Moreover, the one count of arson with which he was charged was in effect a rolled-up count, incorporating the three buildings and the vehicle which he damaged, the financial cost of which was in excess of $400,000, not to mention the financial and emotional consequences for the owners of the businesses conducted from the premises. It is plain, for example, from the victim impact statement of the owners of the bakery, that they suffered very significant dislocation and financial deprivation.[14]
22 The judge set out in some detail the personal circumstances of the appellant and his criminal history. As there appears, he had a difficult childhood and adolescence, which led to the abuse of alcohol and amphetamines, and they played a part in the commission of the subject offences. At the time of the offences he was in a stable relationship with a young woman but for one reason or another he had absented himself from his regular employment and he was indulging himself in a life of indolence and the abuse of alcohol and amphetamines. He admitted to two previous court appearances on the second of which, in March 2002, he was convicted of a number of offences, including three of criminal damage for which he received a good behaviour bond and a fine, and it is significant that he committed the subject offences whilst on a good behaviour bond.
23 The maximum sentence for the offence of arson is 15 years' imprisonment and for the offence of theft is 10 years' imprisonment. The nature of the offences in this case calls for sentences which reflect the court's denunciation of the appellant's conduct and which provide general deterrence. It is also apparent that, despite previous opportunities to mend his ways in the form of lenient sentences and non-custodial dispositions, the appellant continued to offend, and with increasing seriousness. The sentences now to be imposed must therefore provide an appropriate degree of specific deterrence, as well as just punishment for the damage and for the hardship which his offending has imposed on others.
24 Those considerations need then to be balanced against his early plea of guilty and his undertaking to co-operate to give evidence against his co-accused, and what appears to me from his plea and undertaking and from his evidence at the plea hearing to be genuine remorse. I also bear in mind his significantly disadvantaged background, his relative youth and the primacy of rehabilitation for which it calls, and the favourable prospects for rehabilitation which the stability of his relationship with his partner and the birth of their first child may be thought to imply.
25 It was submitted by counsel for the appellant that it was necessary as well to allow for some degree of parity as between the sentence to be imposed upon the appellant and the sentences which were imposed upon his co-offenders. In support of that contention, counsel referred to observations of Eames, J.A. in R. v. Pham and Nguyen,[15] where his Honour said that he did not think it appropriate to exclude the possibility that even where co-offenders are sentenced in respect of different crimes, parity may have a role to play. It appears to me, however, that counsel for the Crown is correct in the submission that the answer to the appellant's contention appears also in the observations of Eames, J.A. in R. v. Pham and Nguyen, to the effect that where the sentences in respect of which co-offenders are sentenced are significantly disparate, there really is no room for any degree of parity. As it seems to me, that is so here. Upon the version of facts which was accepted by the sentencing judge, the co-offenders were to a substantial if not equal degree involved in the offences for which the appellant was sentenced. But in the end they were convicted and sentenced only for offences of much lesser gravity.
26 Balancing those considerations to the extent I am able, I would re-sentence the appellant on count 1, for the offence of arson, to a term of imprisonment of three years, and on count 2, for the offence of theft, to a term of imprisonment of six months, making for a total effective sentence of three years' imprisonment. Bearing in mind his youth, the degree of his remorse, and what I assess to be his chances of rehabilitation, I would set a non-parole period of 18 months.
27 It should be understood, however, that the sentence and non-parole period I propose are markedly below the levels that would ordinarily be appropriate for offences of the nature and gravity committed by the appellant. It is only because of the significant discounts on sentence that I think are to be allowed for his plea of guilty and, more importantly, his undertaking to give evidence for the Crown against his co-offenders that such a degree of leniency may be regarded as warranted in this case.
