1 SULLY J: I have had the benefit of reading in draft the reasons of Adams J. I agree with the orders proposed by his Honour.
2 I am in general agreement with his Honour's reasons for the making of those orders; but, with respect, I do not agree with what seems to me to be the thrust of what is conveyed by paragraph 10 of his Honour's reasons.
3 His Honour refers in paragraph 10 to the decision of this Court, (Spigelman CJ, Wood CJ at CL, Foster A-JA, Grove and James JJ), in R v Thomson and Houlton (2000) 49 NSWLR 383. That decisions stands as authority for the proposition that: 'The utilitarian value of a plea to the criminal justice system should generally be assessed in the range of 10-25 per cent discount on sentence. The primary consideration determining where in the range a particular case should fall, is the timing of the plea. What is to be regarded as an early plea will vary according to the circumstances of the case and is a matter for determination by the sentencing judge.'
4 That proposition is not, however, the sole guidance given to sentencing Judges in connection with the vexed question of allowing, in consideration of a plea of guilty, a reduction in what would otherwise be an appropriate sentence. As the guideline judgment itself recognises, the basic proposition as quoted above raises necessarily the cognate question of the extent, if any, of an obligation on the part of the particular sentencing Judge, not only to refer to the fact that a reduction of sentence is being conceded, but to state in percentage terms a precise quantification of the discount that is actually being allowed in the particular case.
5 In that latter regard the guideline judgment is, as I respectfully think, completely clear. The relevant portion of the guideline is expressed as follows:
"(ii) Sentencing judges are encouraged to quantify the effect of the plea on the sentence in so far as they believe it appropriate to do so. This effect can encompass any or all of the matters to which the plea may be relevant - contrition, witness vulnerability and utilitarian value - but particular encouragement is given to the quantification of the last-mentioned matter. Where other matters are regarded as appropriate to be quantified in a particular case, for example, assistance to authorities, a single combined quantification will often be appropriate."
6 I apprehend that it is completely clear from that statement of principle that the guideline judgment did not intend to impose upon a sentencing Judge a precise obligation to state in quantified percentage terms the extent of the relevant discount that was being allowed in the particular case. Any suggestion that a failure on the part of the sentencing Judge to express himself in such a precise mathematical percentage way manifests error of sentencing principle should be, in my opinion, firmly refuted. I would refute similarly any suggestion that, although it might not be, in a precise and technical sense, an error of law for a sentencing Judge not to nominate a discount in precise percentage figure terms, it is nevertheless in some way either improper or undesirable for such a quantification not to be made. I take that stand because I think the time has come to acknowledge something that practical experience in the wake of the guideline judgment has plainly demonstrated: namely, that, if I may put the point in this way, one man's transparency is another man's artifice.
7 It is, in my opinion, of considerable practical importance to the just operation of the law of sentencing in criminal cases to keep a firm grasp of the basic principles that were re-affirmed as recently as 2005 by the High Court of Australia in Markarian v The Queen (2005) 215 ALR 213. In the context of the present discussion it will do no harm to reproduce certain of the passages in the joint judgment of Gleeson CJ and Gummow, Hayne and Callinan JJ:
"[27] Express legislative provisions apart, neither principle, nor any of the grounds of appellate review, dictates the particular path that a sentencer, passing sentence in a case where the penalty is not fixed by statute, must follow in reasoning to the conclusion that the sentence to be imposed should be fixed as it is. The judgment is a discretionary judgment and, as the bases for appellate review reveal, what is required is that the sentencer must take into account all relevant considerations (and only relevant considerations) in forming the conclusion reached. As has now been pointed out more than once, there is no single correct sentence. And judges at first instance are to be allowed as much flexibility in sentencing as is consonant with consistency of approach and as accords with the statutory regime that applies."
"[37] (There is a general discussion of certain aspects of the reasoning of the Court in the earlier decision of Wong v The Queen (2001) 207 CLR 584. Reference is made to extracts taken from the reasons of Gaudron, Gummow and Hayne JJ in that matter. Having expressed the view that what is commonly described as the "two-tier" approach to sentencing is "wrong in principle", Gaudron, Gummow and Hayne JJ explain by reference to particular examples why they are of that view. One of the examples is expressed by their Honours as follows, and in a passage which is quoted in [37] of the joint majority judgment in Markarian .):
"To take another example, to 'discount' a sentence by a nominated amount on account of a plea of guilty, ignores difficulties of the kind to which Gleeson CJ referred in R v Gallagher when he said that:
'It must often be the case that an offender's conduct in pleading guilty, his expressions of contrition, his willingness to co-operate with the authorities, and the personal risks to which he thereby exposes himself, will form a complex of inter-related considerations, and an attempt to separate out one or more of those considerations will not only be artificial and contrived, but will also be illogical.'
So long as a sentencing judge must, or may, take account of all of the circumstances of the offence and the offender, to single out some of those considerations and attribute specific numerical or proportionate value to some features, distorts the already difficult balancing exercise which the judge must perform. [emphasis in original]"
"[39] Following the decision of this court in Wong it cannot now be doubted that sentencing courts may not add and subtract item by item from some apparently subliminally derived figure, passages of time in order to fix the time which an offender must serve in prison. That is not to say that in a simple case, in which, for example, the circumstances of the crime have to be weighed against one or a small number of other important matters, indulgence in arithmetical deduction by the sentencing judges should be absolutely forbidden. An invitation to a sentencing judge to engage in a process of 'instinctive synthesis', as useful as shorthand terminology may on occasions be, is not desirable if no more is said or understood about what that means. The expression 'instinctive synthesis' may then be understood to suggest an arcane process into the mysteries of which only judges can be initiated. The law strongly favours transparency. Accessible reasoning is necessary in the interests of victims, of the parties, appeal courts, and the public. There may be occasions when some indulgence in an arithmetical process will better serve these ends. This case was not however one of them because of the number and complexity of the considerations which had to be weighed by the trial judge."
8 I apprehend that the reasoning which is advanced in paragraph 10 of Adams J's reasons draws in substance upon what is said in the previously quoted paragraph [39] of the joint majority reasons in Markarian. In my opinion it can be allowed at once that what is said in paragraph [39] is authority for the proposition that in an appropriately simple case "indulgence in arithmetical deduction" should not be "absolutely forbidden". I apprehend, however, that it would be quite mistaken to take what is said in paragraph [39] as being intended to cut down in any way the things earlier said in paragraph [27].
9 I apprehend that no conscientious sentencing Judge would wish ever to pass a sentence of imprisonment which was not transparent if, by that expression, is meant the manifest logical application of principles correctly perceived to facts correctly found. That approach to the notion of transparency is, however, a very different one from an approach which rhetorically invokes transparency as the means of injecting into the sentencing process multiple mutations of imaginative, but intrinsically adventitious, forensic mathematics. The logical ultimate conclusion of the second approach runs, in my opinion, the real risk of becoming the Trojan horse for grid sentencing, which is the ultimate negation of the principled fashioning of an individual sentence in connection with an individual offence committed by an individual offender.
10 BARR J: I have had the advantage of reading in draft the judgment of Adams J and I agree with his Honour's conclusion as to the inadequacy of the sentence appealed from. I would allow the appeal, quash the sentence and substitute the one proposed by his Honour.
11 However, my agreement does not extend to any criticism of the sentencing judge for declining to attribute a precise proportion or number of percentage points to the utilitarian value of the plea of guilty. Sentencing judges are encouraged to quantify this effect of pleas of guilty insofar as they believe it appropriate to do so: R v Thomson; R v Houlton [2000] NSWCCA 309 per Spigelman CJ at [160] (ii), with whose judgment the remaining members of the Court agreed. But encouragement falls short of requirement. The utilitarian value of a plea of guilty can hardly ever be the only feature of a case tending towards a lesser sentence. It was not in the present case. Consistently with the judgment of this Court in R v Thomson; R v Houlton, the Court ought to respect the opinion of the sentencing judge. When reminded that he had not quantified any discount other than that for future assistance, his Honour said -
I am aware of that and I did not do it. It becomes too mathematical once you get into more than one category of discount.
12 Presumably his Honour had in mind the artifice involved in attributing values to features which, though individually identifiable, do not stand alone uninfluenced by and not influencing other individually identifiable features. See the judgment of Gleeson CJ in R v Gallagher (1991) 23 NSWLR 220 at 226-230. The sentencing judge took an instinctively synthetic approach, and that was consistent with authority: Markarian v The Queen [2005] HCA 25.
13 I have read the judgment of Sully J and agree with his Honour's observations.
