In all cases the important consideration is to expose the transparency of the process so that it can be seen that an appropriate discount has been allowed.
17 Time and again this Court is left to try to fathom what discount was given, either for pure utilitarian value or in combination with contrition, in cases where the judge has not referred to the fact that a discount was given or the value of it, when a simple statement of the percentage value of the discount or the starting point of the undiscounted sentence would have revealed whether the sentencing discretion miscarried on that account."
24 In the case of a Federal offender, it is the willingness of that offender to facilitate the course of justice, the acceptance of responsibility and the expression of contrition, that are each conveyed by a plea, which gives rise to an entitlement to a discount for that factor: Cameron v The Queen (2002) 76 ALJR 382.
25 The availability of a discount for assistance, depending on its worth, in order to foster the interests of law enforcement and to recognise the contrition involved as well as the potential risks to the offender, is well recognised: R v Salameh (1991) 55 A Crim R 384, R v Gallagher (1991) 23 NSWLR 220, R v Cartright (1989) 17 NSWLR 243 and R v Dinic NSWCCA 3 September 1997. It is important, if the purpose for allowing a discount is to be achieved, that the offender standing for sentence be clearly appraised of the fact that a benefit was conferred. That will not be conveyed by a bare statement of the kind that was made in this case that the assistance was judged to have been "substantial and beneficial".
26 The level of the discount has customarily been accepted as falling within the range of 20 to 50% R v Chu NSWCCA 16 October 1998, R v Pang [1999] 105 A Crim R 474 and R v El Hani [2004] NSWCCA 162 at para 71. An allowance at the upper end has been reserved for cases where there has been particularly significant assistance, usually involving the offender accepting an obligation to give evidence against other offenders.
27 Where the factors of a plea and assistance are each available, it does not follow that any resulting discount is to be compounded or accumulated: R v Sharma [2002] NSWCCA 142 and R v Hameed [2001] NSWCCA 287. Otherwise there is a risk of the sentence becoming one which is not of a severity appropriate in all of the circumstances of the case. In such cases a combined discount will normally be appropriate: Thompson and Houlton at para 129; El-Hani at paras 65 to 70, and R v Zaluaga-Gomez [2002] NSWCCA 358.
28 The absence of any sufficient reference to the discount that was allowed, and the observations of his Honour concerning s 16G, make it appropriate, in my view, for the Court to review for itself whether some sentence other than that imposed should have been passed, in the light of the plea and the assistance, and in the light of what should now be regarded as an appropriate range of sentences for a courier, involved in the importation of heroin in a comparable quantity. In that regard reference to the decision in Wong and Leung continues to be of some assistance, so long as it is recalled that the guideline range of six to nine years there proposed for a mid level trafficable quantity of heroin assumed a s 16G discount.
29 That review has been assisted by an examination of the sealed letter in which the details of the Applicant's assistance are to be found. I have also made reference to several comparative cases such as R v Chu NSWCCA 16 October 1998, R v Auv [2002] NSWCCA 375, R v Lee and Ng NSWCCA 20 December 1996, R v Karacic (2001) 121 A Crim R 7, R v Elchami NSWCCA 15 December 1995, R v K [2000] NSWCCA 200, R v Huang (2000) 113 A Crim R 386 and R v Olbrich (2000) 117 A Crim R 326, all of which were decided when s 16G was in force; and to post repeal decisions such as R v Dang [2004] NSWCCA 265, and R v Dang [2004] NSWCCA 269. In that regard, I accept that these cases represent only a sample of the cases that make up the range and that there are inevitably differences in their objective and subjective circumstances: R v Morgan (1993) 70 A Crim R 368 and R v Trevenna [2004] NSWCCA 43.
30 However, so far as they provide some general guidance as to the range, subject to the discount that was given where it was applicable, they are capable of being taken into account in an attempt to secure some general consistency in sentencing: R v Henry (1999) 46 NSWLR 346, R v Oliver (1980) 7 A Crim R 174 at 177.
31 Having read the Letter of Assistance and having examined the decisions mentioned, I am not persuaded, allowing for a combined discount in the order of 40 to 50% for the plea and assistance, which I consider to have been appropriate in the present case, that the sentence was outside a permissible sentencing range. In this regard the sentence does not appear to be excessive having regard to the range and the sentencing pattern which existed before the repeal of s 16G. Moreover, as I have already noted, despite the Applicant's subjective circumstances, this was not the case of an unwitting courier duped into a narcotics run. Rather it involved a cool headed decision to become involved in an illegal and risky venture for a considerable sum of money.
32 I am also not persuaded that a lesser non-parole period should have been fixed. The period of 4 years 6 months represented 64% of the term, and as such it was within the conventional range of 60 to 66.6% referred to in R v Bernier (1998) 102 A Crim R 44.
33 I would grant leave to appeal but I would dismiss the appeal.
34 HULME J: I agree with the orders proposed by Wood CJ at CL and, subject to the following remarks, with his Honour's reasons. My principal point of difference lies in his Honour's remarks concerning the effect of the repeal of Section 16G of the Crimes Act (Cth).
35 I of course accept, it having been laid down by Parliament in Section 16A of that Act that a court, sentencing an offender in this area "must impose a sentence or make an order that is of a severity appropriate in all the circumstances of the offence". That is the law now. It was the law when Section 16G was in operation albeit the severity appropriate then had to reflect the requirements of that section which was regarded as mandating a significant discount.
36 Furthermore I accept that sentencing is not a simple mathematical exercise. However, in part sentencing deals in figures. Parliament has used them in setting maximum terms of imprisonment and sentences are expressed by reference to them. Factors taken into account in sentencing are not uncommonly expressed in mathematical terms. Thus in R v Thomson and Houlton 2000 49 NSWLR 383 the guideline laid down for the discount to be applied for the utilitarian value of a plea of guilty was expressed in percentages. A similar approach, using percentages or fractions, has commonly been adopted in discussions concerning the allowance or discount to be afforded to offenders for assistance to the authorities - see for example El Hani [2004] NSWCCA 162 at [71 - 74]; R v Chu (unreported, CCA, 16 October 1998); R v Cartwright (1989) 17 NSWLR 243 at 255-6. When s16G was in operation, the allowance or reduction in sentence which, in the circumstances of sentencing in New South Wales, was required by the section was commonly expressed in terms of one third or a percentage (not necessarily 33 1/3%).
37 Against this background there can be no sensible criticism of the use of figures or mathematics in expressing the consequences of the repeal of s16G. Furthermore it follows as the night the day that, all other things remaining the same, if one omits from a particular starting point a discount of approximately one-third then, the result will be approximately 50% higher than if the discount had been applied. The fact that such a result is, or can be described as, "mathematical" does not invalidate it.
38 In R v Dang [2004] NSWCCA 269, where the sentencing judge had increased a figure of 8 years to 12 years to reflect the repeal of s16G, Hidden J, with whom the Chief Justice and Buddin J agreed, saw nothing wrong with this approach, providing that mathematics were kept in their proper place.
39 As Howie J, with whom Grove J and Newman AJ agreed, in R v Studenikin [2004] NSWCCA 164 at [43] pointed out,
"To give effect to the sections (16G and 19AG), the courts in this State proceeded to sentence a Federal offender by determining the appropriate head sentence and non-parole period by the application of normal sentencing principles and the relevant provisions of the Crimes Act (Cth) and then, before pronouncing the sentence reduced it by a period of about a third."
40 At [62 - 63], his Honour continued:-
"62 In any event, it is wrong, in my view, to approach this matter on the basis that it involves a question of whether the courts in this State should increase sentences as a result of the repeal of s 16G. The issue is rather whether the courts in this State have the power to continue to apply the discount authorised by s 16G after the repeal of that provision. If this issue is stated in this way, the answer is obvious. In the absence of a statutory warrant to do so, a court has no power to reduce a sentence that has been determined by a proper application of the sentencing principles laid down by the statute or the common law to the facts and circumstances of the particular case. It seems to me, with respect, to be a matter of common sense and simple logic, that, if the courts of this State have been reducing the sentences imposed upon Federal offenders by reason only of the operation of a specific statutory provision, the courts can no longer reduce sentences in that way once the statutory authority to do so has been withdrawn.
