Determination
35Section 5DA of the Criminal Appeal Act is as follows:
"5DA Appeal by Crown against reduced sentence for assistance to authorities
(1) The Attorney General or the Director of Public Prosecutions may appeal to the Court of Criminal Appeal against any sentence imposed on a person that was reduced because the person undertook to assist law enforcement authorities if the person fails wholly or partly to fulfil the undertaking.
(2) On an appeal the Court of Criminal Appeal may, if it is satisfied that the person has failed wholly or partly to fulfil the undertaking, vary the sentence and impose such sentence as it thinks fit.
(3) A reference in subsection (1) to a sentence imposed on a person includes a reference to a sentence that was varied or imposed by the Court of Criminal Appeal."
36Since 14 March 2011, s 23 of the Crimes (Sentencing Procedure) Act has relevantly been as follows:
"23 Power to reduce penalties for assistance provided to law enforcement authorities
(1) A court may impose a lesser penalty than it would otherwise impose on an offender, having regard to the degree to which the offender has assisted, or undertaken to assist, law enforcement authorities in the prevention, detection or investigation of, or in proceedings relating to, the offence concerned or any other offence.
...
(4) A court that imposes a lesser penalty under this section on an offender because the offender has assisted, or undertaken to assist, law enforcement authorities must:
(a) indicate to the offender, and make a record of the fact, that the lesser penalty is being imposed for either or both of those reasons, and
(b) state the penalty that it would otherwise have imposed, and
(c) where the lesser penalty is being imposed for both reasons-state the amount by which the penalty has been reduced for each reason.
(5) Subsection (4) does not limit any requirement that a court has, apart from that subsection, to record the reasons for its decisions.
(6) The failure of a court to comply with the requirements of subsection (4) with respect to any sentence does not invalidate the sentence."
37Considering the portions of the remarks on sentence that I have extracted as a whole, I am of the opinion that it is tolerably clear that his Honour was imposing a lesser sentence for both past and future assistance. I refer especially to what his Honour said about the identification of a criminal network, and the identification of weaknesses or errors in the Crown case against others.
38In those circumstances, I respectfully agree that, pursuant to s 23(4) of the Crimes (Sentencing Procedure) Act, it was incumbent upon his Honour to quantify the discounts for past and future assistance: see LB v R [2013] NSWCCA 70. Unfortunately, neither party at first instance reminded his Honour of the legislation that had commenced months before, and that had effected a significant change to sentencing practice.
39The result is that this Court must attempt to construe the various components of the global discount provided by his Honour in order to determine this appeal. To the extent that that exercise may be impossible to achieve with complete accuracy, I consider that this Court should make its own assessment.
40Turning first to the discrete discount for the utilitarian value of the plea of guilty, in light of the lateness of the plea, its very limited utilitarian benefit, and the repeated emphasis given to those matters by his Honour, I consider that the discount for the utilitarian value of the plea of guilty could not have been more than 5 per cent.
41Turning to past assistance, it is true that, with the benefit of hindsight, it appears that that assistance was very likely worthless, in light of subsequent events that destroyed the credibility of the respondent. And it is clear from the terms of s 5DA(2) of the Criminal Appeal Act, that, if an appeal pursuant to the section is upheld, this Court is not limited merely to reapplying the discount that was given for an unfulfilled promise with regard to future assistance. This Court many resentence "as it thinks fit". That state of affairs argues for this Court applying no discount for past assistance, since it could be said that the subsequent behaviour of the respondent has shown the true value of the assistance given before the imposition of sentence.
42However, it is not completely clear that the past assistance was of no value whatsoever. While the credibility of the respondent has been rendered nugatory, the identification of a criminal network may well have had some intrinsic benefit. The Crown did not place evidence before this Court to demonstrate that that aspect of the past assistance of the respondent must be assessed as worthless.
43In those circumstances, I consider that this Court should assess the discount given by the learned sentencing Judge to the respondent with regard to past assistance, rather than imposing a new sentence that provides no reflection of it.
44His Honour assessed the past assistance as having some utility. As I have said, his Honour was of the view that a criminal network had been identified, and that the material provided by the respondent had the potential to help identify (and perhaps repair) the weaknesses in the Crown case against the purported co-offenders.
45But the value of that past assistance could hardly compare to the proposed future assistance of giving evidence founded upon a lengthy recorded interview against two alleged co-offenders with regard to a very grave offence. In short, I consider that this Court should regard the discount that was provided for past assistance as being 5 per cent.
46Finally, I respectfully reject the submission of the respondent that some discrete component of the discount was founded upon hardship to the respondent or his family. My rejection of that submission has two bases.
47The first is that, in light of the seriousness of the offence, it was inevitable that the respondent would be sentenced to full-time custody in any event. In other words, the intrinsic hardship to the respondent and his family of him being incarcerated had nothing to do with his assistance to the authorities. Secondly, as his Honour made clear in the second sentence of the portion of the remarks on sentence extracted by me at [19], the hardship arising from his conditions of custody as a result of his assistance to the authorities was reflected in the discount given for past and future assistance. It was not the subject of a separate discount. That is entirely consonant with established sentencing practice: see R v Perez-Vargas & Stevens (1986) 8 NSWLR 559; (1986) 25 A Crim R 194 and R v Gallagher (1991) 23 NSWLR 220.
48In summary, I consider that the global discount provided by his Honour was founded on the utilitarian value of the plea of guilty (5 per cent), the past assistance (5 per cent), and the future assistance (15 per cent). I do not consider that any aspect of the incarceration of the respondent gave rise to a separate discount that should be factored into the new sentence to be imposed.
49It follows that I assess the component of the global discount referable to future assistance as being 15 per cent. It is that discount that must now be removed from the sentence imposed by his Honour. The correct mathematical approach is as follows.
50First, remove the 25 per cent discount from the imposed head sentence of imprisonment for 6 years 6 months and the non-parole period of 4 years, arriving at a starting point of a head sentence of imprisonment for 8 years 8 months.
51Secondly, apply a 10 per cent discount (made up of the 5 per cent discount for the plea of guilty and the 5 per cent discount for past assistance at the time of the sentence) to that starting point. That calculation results in a discounted head sentence of imprisonment for 7 years 9 months.
52Thirdly, impose a new non-parole period that replicates the ratio between the head sentence and non-parole period of 61 per cent created by his Honour. That leads to a new non-parole period of 4 years 9 months.
