(4) Assessment of the significance of mental illness in this case
83In R v Engert (1995) 84 A Crim R 67, Gleeson CJ observed at 71:
"A moment's consideration will show that the interplay of the considerations relevant to sentencing may be complex and on occasion even intricate. In a given case, facts which point in one direction in relation to one of the considerations to be taken into account may point in a different direction in relation to some other consideration. For example, in the case of a particular offender, an aspect of the case which might mean that deterrence of others is of lesser importance, might, at the same time, mean that the protection of society is of greater importance. That was the particular problem being examined by the court in the case of [Veen (No 2) (1988) 164 CLR 465]. Again, in a particular case, a feature which lessens what might otherwise be the importance of general deterrence might, at the same time increase the importance of deterrence of the offender. [at 68]
...
In truth, however, ... the question of the relationship, if any, between the mental disorder and the commission of the offence, goes to circumstances of the individual case to be taken into account in the application of the relevant principles . The existence of such a causal relationship in a particular case does not automatically produce the result that the offender will receive a lesser sentence, any more than the absence of such a causal connection produces the automatic result that an offender will not receive a lesser sentence in a particular case. For example, the existence of a causal connection between the mental disorder and the offence might reduce the importance of general deterrence, and increase the importance of particular deterrence or of the need to protect the public. By the same token, there may be a case in which there is an absence of connection between the mental disorder and the commission of the offence for which a person is being sentenced, but the mental disorder may be very important to considerations of rehabilitation, or the need for treatment outside the prison system." [at 71] (emphasis added)
84I am of the opinion that there was sufficient historical clinical and recorded medical material available to both Dr Giuffida and Dr Westmore (to which no objection was taken) for them to form and express the opinions that they did on the question of any relationship that may have existed between the applicant's mental health and his offending. With respect to the sentencing judge's reservations referred to in paragraph [79] above, the validity of their opinions was not wholly or even mainly dependent on the history provided by either the applicant himself for his partner.
85However, as earlier indicated, that said, it is necessary to go beyond the medical opinions which were to the effect that the applicant's mental illness, in some relatively undefined way, had a direct role in the commission of the offences.
86It is clear from the observations of Gleeson CJ in Engert (supra) that a more searching analysis of the evidence is required, if a causal connection with the offending is suggested, in particular, in order to identify the basis or way in which the applicant's psychotic illness played a role in the commission of the offences. There, of course, was no evidence that the applicant's schizophrenic illness itself induced the commission of the offences. There was no evidence that the applicant was driven by impulses which he was unable to control or that he had no understanding or comprehension of what he was doing in undertaking the planning and in carrying out the Commonwealth and State offences. Finally, it was not established in evidence, as was submitted on his behalf at the sentencing hearing, that he was delusional or acting under the influence of any delusions in committing the offences. In any event, as the Chief Justice observed in Engert (supra) at 71:-
"... The existence of such a causal relationship in a particular case does not automatically produce the result that the offender will receive a lesser sentence ..."
87Although I have concluded that the medical evidence before the sentencing judge established that the applicant suffered from a psychotic illness at the time of the offences, I do not believe it was such as to establish a relevant causal relationship with his offending in any of the ways referred to in the preceding paragraph.
88The existence of a serious and chronic psychotic illness at the time of the offending may, however, in accordance with established principles, be relevant in assessing the issue of general deterrence or otherwise be taken into account as one of the relevant factors in the sentencing exercise. In that respect, it is no different from that which is involved in every sentencing exercise: R v Currie (NSWCCA, unreported, 25 February 1992) per Gleeson CJ.
89In R v Benetiz [2000] NSWCCA 21 at [36], Simpson J observed:-
"36 ... For mental illness or a psychiatric condition to be relevant to sentencing, it is not necessary that it be the cause of the commission of the crime. Indeed, authority suggest that it is not necessary that it be a cause of the crime. I refer to the decision of this Court in R v Fahda ... There reference was made to a number of authorities of which the following are, on this issue, irrelevant. In R v Letteri ..., Badgery-Parker J said:-
'In each of those cases [which he had, in the preceding paragraph, cited] it appears that the mental illness or retardation was a factor inducing the commission of the offence but that is not a necessary condition of the application of the principle .'" (emphasis added)
90Simpson J also observed in Benetiz (supra) at [38]:-
" A mental disorder such as the applicant's depression was identified by Gleeson CJ in Engert as being part of the circumstances of the individual case. Generally speaking, the well-known authorities indicate that mental disorder may be relevant to the assessment of the offender's culpability and to the levels of which it is appropriate to give greater or lesser emphasis to principles of general or specific deterrence ... "
91See also TC v R [2009] NSWCCA 296 at [68] to [70].
92In Courtney v R [2007] NSWCCA 195, Howie J at [83] observed:-
"The fact that an offender is mentally ill does not mean that the sentence imposed must be less than that imposed upon a person who commits the same criminal act without any abnormality of mind ..."
93The issue of the applicant's mental illness must be considered in the factual context of the case. The applicant over a period of time played a key role at a high level within an ongoing drug enterprise in relation to both the conspiracy to import cocaine and in the supply of that drug in this State. Although there is medical evidence to support the proposition that the applicant's mental illness did play a direct role in the offending, the medical specialists did not analyse in any detail the nature and extent of the applicant's activities associated with conspiracy or the supply offences before expressing that opinion.
94It is unnecessary here to analyse in detail all the factual matters set out in the lengthy Statement of Facts tendered at the sentencing hearing. However, in order to appreciate the nature and level of the applicant's participation in the serious criminality involved in both the conspiracy offence and the supply offence, the following matters are noted:-
(1) The Statement of Facts and the listening device material tendered in the Crown case established that the applicant was involved with co-offenders, Hurley, Mara and North in an on-going conspiracy to import a commercial quantity of cocaine.
(2) The applicant was involved in critical decision-making as to the timing of the importations. He managed his side of the operation to coincide with the work rosters of corrupt airport workers.
(3) The applicant received a significant share of the proceeds of the importation made on 8 October 2004 of 10 kilograms of cocaine. He arranged couriers and financing for the purchase of the cocaine.
(4) The applicant and a co-offender, in relation to the proposed importation intended to occur in May 2005, arranged for another to be given US$100,000 and 37,500 Euros to be used by the other co-offender to purchase cocaine in South America.
(5) Whilst there was evidence of an intention between the co-offenders Hurley and Mara that 20 kilograms of cocaine were to be imported in the May 2005 importation, it was the applicant who intended that a further 10 kilograms of cocaine be purchased (for which he provided the funds). The Crown submission was that the applicant's decision to increase the amount to be imported of the proposed importation from 20 to 30 kilograms was to maximise profit to himself. In consequence, the importation was evidence of decision-making which was consistent with the applicant's role as a principal.
95It was the Crown's submission to the sentencing judge that the evidence supported the conclusion that the applicant was, with Hurley, at the top of the hierarchy in the conspiracy and that both men brought particular expertise to bear in carrying out the objects of the conspiracy. The material before the sentencing judge supported that submission.
96The State offence committed by the applicant involved a continuing criminal enterprise or activity. It incorporated seven individual acts of supply by the person "Tom" at the applicant's request. Those supplies occurred on and between 8 February 2005 and 17 March 2005.
97The Crown submission was that the amount of cocaine involved in the criminal enterprise the subject of the State charge was significant, being almost seven kilograms - about seven times the large commercial quantity of cocaine specified in the Drugs Misuse and Trafficking Act: Crown Submissions on Sentence at [62].
98The Crown submission was that the applicant was a principal in relation to the seven sales the subject of the charge.
99The applicant was sentenced on the basis of State offence together with the offences on the Form 1.
100The facts established in evidence for the purpose of the sentencing hearing, accordingly, did not demonstrate any particular incapacity, delusions or other mental illness factors contributing to the serious offences committed by the applicant over a period of time.
101Whilst there was medical evidence to the effect that there are different types of schizophrenia and that it is possible for some people with paranoid delusions to perform tasks involving planning, sometimes quite complex planning, and organise matters, there was no detailed analysis of the applicant's criminal activities by the two psychiatrists.
102I have earlier noted that Dr Giuffida considered that the applicant's mental illness would have almost certainly caused a marked impairment of his capacity to exercise reasonable and sensible judgment: Report of Dr Giuffida, 6 May 2008 at AB 327.
103As earlier indicated, the evidence referred to above in relation to the conspiracy and supply offences failed to demonstrate any impairment in the applicant's capacity to undertake those activities. Indeed, the evidence to which I have earlier referred points in the opposite direction.
104That leaves, as a matter of possible interpretation, that Dr Giuffida, in referring to the applicant's capacity to exercise reasonable and sensible judgment may have been indicating that the applicant's judgment was impaired in the sense of him making the decision to become involved in the importation and supply of cocaine. Whilst it is, of course, possible that a person suffering from a psychotic illness may be more vulnerable to entering into an ongoing criminal activity, there would need to be a proper factual foundation to support the conclusion that that is what contributed to the applicant's decision to become involved. There was no such evidence in this case to that effect.
105The detailed Remarks on Sentence reveal a close consideration by the sentencing Judge to the issue of the applicant's mental illness. The question as to any possible relevance of the applicant's mental illness to his offending arises in circumstances in which the unusual nature of the offending allows for very little scope for mental illness, in this case, to operate or provide an explanation for the applicant's engagement in the criminal activity involving a high level of culpability.
106On the particular facts of this case, I do not consider that the approach taken by the sentencing Judge has been shown as one involving appellable error. I, with respect, agree with the conclusion of Morgan DCJ that the conspiracy offence involved a level of criminality of such a high order that it was essential that the sentence to be imposed for that offence reflect the element of general deterrence.
107Again, having regard to the particular circumstances of this case, there is, in my opinion, no basis for intervening in relation to the sentencing Judge's approach to taking into account the mental health issue in specifying the non-parole period, as determined in this case.
