38 After making this rather startling finding, his Honour went on to impose the sentence to which I have referred.
39 The submission in relation to this aspect of the matter is that there is a justifiable sense of grievance on the part of the applicant arising out of the disparity between the sentence he received before Chief Judge Blanch and the sentence imposed by Patten DCJ on Mr Nguyen on 26 May 2000. (See Postiglione v Regina (1997) 189 CLR 295 at 301 in the joint judgment of Dawson J and Gaudron J).
40 It is necessary for me, having set out at some length these submissions, to turn now to the way in which they should be treated by this Court. First, it should be recognised that his Honour found that the applicant was entitled to the maximum concession for his early plea of guilty, as I have set out earlier.
41 Secondly, it cannot be said that his Honour failed to take into account at all the subjective features which have been stressed in both written and oral argument. The applicant's age, serious criminal history, long term addiction, the fact that he had not been to gaol before, the fact that he had complied with the terms of an earlier recognisance were taken into account. So were the reasons for his involvement in the supply and the possession of heroin and the need for his own continued supply.
42 His Honour also referred to Dr Lucire's description of the applicant's mental disorder and the relationship between his previously undiagnosed and untreated condition and the applicant's continued addiction to heroin at the age of almost 50. Indeed, in relation to the last matter, it was plainly an important reason leading to his Honour's decision to find special circumstances so as to vary the statutory ratio between the head sentence and the non parole period.
43 Thirdly, I believe his Honour did take into account the nature of the approach to the applicant by the police officer undercover agent.
44 In relation to the sentence imposed, having regard to the statistics, it is towards the very top of the range. Some caution needs to be exercised in relation to those statistics. First, they do not involve a significant number in terms of a sample. Second, the statistics include, no doubt, instances of single supply and deemed supply. Nevertheless they do provide a guide to suggest that this sentence was towards the top of the range and that much is conceded by the Crown.
45 It is perfectly clear why his Honour imposed the sentence he did. The seriousness of the crime and the need for the sentence to reflect the general deterrence were the stated reasons which led to the sentence imposed on the applicant. I would not wish for myself in any way to detract from the relevance of the matters which his Honour saw as generally significant in determining the sentence, particularly in relation to an assessment to its overall objective seriousness.
46 There is, however, one matter in particular which leads me to believe this Court should intervene in the present matter. This is because I do not believe that the applicant was an appropriate vehicle for sentence which reflected general deterrence to the extent this sentence did. This is because of the applicant's mental disorder. A number of authorities in relation to this matter are set out in a decision of mine in Regina v John Alexander (2000) NSWCCA 458 at paras 41 to 43 - (see especially R v Fahda (1999) NSWCCA 267; R v Sconamiglio (1991) 56 A Crim R 81; R v Letteri (unreported NSWCCA 18 March 1992) and R v Henry (1999) 46 NSWLR 346 per Wood CJ at CL at 394). It is clear from these authorities that the existence of a mental disorder will not lead necessarily to the imposition of a sentence which ignores the aspect of general deterrence. Far from it. Such a condition may, normally be a factor which has the capacity, however, to influence the extent to which the aspect of general deterrence will be operative in a particular sentence.
47 In the present case, the relationship between the applicant's medical condition, his continued addiction and the circumstances of supply revealed in the evidence, persuade me that it was not appropriate, for reasons of general deterrence, to place this applicant's sentence towards the top of the range.
48 Secondly, having heard the elaboration of the arguments today, I am also persuaded that the applicant's general level of criminality did not fall into the higher category warranting the imposition of penalty at the level it was imposed. The applicant's addiction to heroin, the fact that he was not supplying for gain, the fact that supplies were made to an undercover policeman who importuned the supply, the fact that the supplied drugs were very much less than commercial quantity and would not find their way into society generally for the purposes of consumption, are all matters which lead me to believe that the sentence imposed by his Honour was at too high a level.
49 Thirdly, again having heard the arguments advanced today, I am persuaded that the subjective matters, although they were taken into account and given weight by his Honour, in their totality pose a real question as to the appropriateness of the sentence imposed.
50 For all those reasons, in my opinion this Court should find that the sentence was manifestly excessive and should intervene in the sentencing process.
51 As to the argument that there is a disparity between the sentence imposed by the Chief Judge and Patten DCJ, I would only say this, erroneously or not, Judge Patten's view was that the criminality of Mr Nguyen was much less than that of the applicant. The parity argument of course centres on this sentence and contrast it with the sentence imposed by Mr Justice Blanch. In my view it is apparent that his Honour Judge Patten misapprehended the nature of the criminality of the applicant and misapprehended the nature of his criminal history.
52 As a consequence, it is my opinion that any sense of grievance which the applicant would have in relation to the sentence imposed on Nguyen by Judge Patten would not legitimately, be a justified sense of grievance. Nor would there be engendered such a sense of grievance in the mind of an objective observer that, in the case of the applicant, justice had not been done (Postiglione v Regina (supra) at 323). For the reasons I have already indicated, it is necessary to re-determine an appropriate sentence. After taking into account a discount for the early plea of guilty, and all the other matters relied upon by the applicant in the written and oral submissions as to circumstances which mitigated the objective criminality of the offence, and taking into account further the subjective circumstances which were relied upon in those submissions, it is my opinion that an appropriate head sentence would be three and a half years. I determine that a non parole period of two and a half years should be set.
53 I propose therefore that leave to appeal be granted, that the appeal be allowed, the sentence of his Honour Justice Blanch be quashed. In lieu thereof the applicant be sentenced as follows: The applicant is sentenced to three and a half years imprisonment with a non parole period of two years six months. The applicant will be eligible to be released on parole, according to my calculations, on 4 February 2002.
54 JAMES J: I agree with the judgment of Whealy J and the orders proposed by his Honour. The sentence would date from 3 August 1999. The orders of the court are as proposed by Whealy J.
