30The applicant submitted in written submissions that contrary to his Honour's finding, the evidence established that he was mentally ill at the time of the commission of the offence in October 2009; and that as a result, his moral culpability for his offence was limited, because his illness contributed to the commission of the offence in a material way. In the result his Honour had erred in failing to conclude that the applicant was an inappropriate vehicle for general deterrence; and in failing to reduce the head sentence, by virtue of that mental illness. In oral submissions it was urged that the mental illness should have ameliorated general deterrence as a factor in the sentence.
31In my assessment these submissions should not be accepted.
32The evidence was that on 1 October 2009 the applicant was admitted to St George Hospital, seemingly after he was assaulted. He was released the next day, with no evidence found as to any head injury, he having been found to be alert and oriented. There was then no suggestion of mental illness. The offence occurred on 29 October 2009. At that time the applicant was on bail in respect of the offence he had committed in May, of which he was later convicted.
33The applicant's conduct that day was clearly irrational, but whether that was the result of a mental illness, or the effects of drugs, is not apparent. In the submissions advanced below, it was conceded that the applicant had drug and alcohol issues, there having been evidence of drinking scotch, smoking $20 pot per day, taking one table of morphine a day, as well as panadeine forte for headaches. That was another possible explanation for the applicant's conduct, but that this was the cause was not established on the evidence.
34The records also show that the applicant was agitated after his arrest on 29 October, then only admitting to marihuana use. On 31 October, florid speech and mood swings were noted, with the question of mental health then raised. On 2 November, the applicant was noted as being tearful, agitated, demanding, irrational and emotionally unstable, distressed and fearful. It is on 6 November that the notes are suggestive of mental illness, recording complaints, for example, of the TV giving the applicant messages, albeit it is also noted that the applicant then suggested that this was a symptom of withdrawal.
35The plea was entered on 9 June 2010, after the applicant was assessed to have been fit to plead on 6 May 2010 by Dr Kasinathan. His report noted that he had spoken to Dr Nguy, consultant psychiatrist who advised that:
"... upon arrival to jail, Mr Arbili had presented as anxious and fearful and was able to speak English. Within weeks his mental state deteriorated, he would only speak Arabic, admitted to hearing voices and feeling paranoid. Dr Nguy diagnosed Mr Arbili with a psychotic disorder and commenced appropriate treatment."
36There was no report from Dr Nguy in evidence, but Dr Kasinathan noted that the applicant was able to speak English on arrest, when he was anxious and fearful and soon began to suffer symptoms consistent with drug withdrawal. Dr Kasinathan was of the view in 2011 that the applicant was suffering from a mental illness, but neither he nor any other expert expressed the view that the applicant was suffering from such an illness at the time of the offence.
37The onus fell on the applicant to establish that the mental illness existed at that time. His Honour concluded that this onus had not been met. That conclusion was open. The evidence relied on to suggest the existence of mental illness was also consistent with the applicant suffering from the effects of his habitual drug use on arrest and later from withdrawal.
38Even if either mental illness or drug and alcohol abuse was a factor in the commission of the offence, that would not necessarily result in the conclusion that a lesser sentence should have been imposed. As discussed in Henry at [173] - [177]:
"173 As a joint judgment of the Court put it in Valentini (1989) 46 ACrimR 23 at 25:
"This Court has said on countless occasions that addiction to heroin is not to be considered as a factor for the reduction of what would otherwise be an appropriate sentence for the nature of the offences which have been committed. It serves, however, to provide an explanation for the commission of the offences."
This has been reiterated in a number of later cases (eg Stanford NSWCCA 23 November 1993; Atkins NSWCCA 27 May 1998).
174 Drug addiction is one of the circumstances of a particular offence that is relevant to the sentencing exercise. It may, for example, be pertinent to the issue of impulsiveness/planning or to the weight to be given to rehabilitation in a particular case.
175 In Engert (1995) 84 ACrimR 67, Gleeson CJ emphasised the complexity of the sentencing task and the multiplicity of the, sometimes conflicting, objectives it must serve. His Honour concluded:
"It is therefore erroneous in principle to approach the law of sentencing as though automatic consequences follow from the presence or absence of particular factual circumstances. In every case, what is called for is the making of a discretionary decision in the light of the circumstances of the individual case, and in the light of the purposes to be served by the sentencing exercise." (68)
176 His Honour went on to say that the existence of a causal relationship between a mental disorder and the commission of an offence does not automatically produce the result that the offender will receive a lesser sentence (at 71). Nor, in my opinion, should the existence of a causal relationship between drug addiction and the commission of an offence.
177 The circumstances in which motive may be a mitigating factor should, in my opinion, be confined to cases in which motive impinges upon the moral culpability of the offender. This can include mental, emotional or medical problems or impulsive conduct. In any event the degree to which motive may be pertinent must depend on the whole of the circumstances. (White NSWCA 23 June 1998 at 24)."
39In Wilmot v Regina [2007] NSWCCA 278, the trial judge did not accept the opinion of an expert that the applicant was suffering a mental illness at the relevant time. Hidden J observed at [26] - [32]:
"26 It is unnecessary to revisit the familiar line of authority dealing with the bearing of mental illness upon sentence: see, for example, R v Engert (1995) 84 A Crim R 67. Undoubtedly, a finding that the applicant's mental illness contributed to his criminal behaviour would have been relevant to an assessment of the objective gravity of his offences. However, that is a matter in mitigation as to which the applicant bore the burden of proof, and there needed to be evidence sufficient to establish it.
27 Certainly, there is a bizarre quality to both offences. This can be seen in the somewhat elaborate planning of the malicious wounding of Mr Mostafa and the ferocity of the attack upon him, as well as in the applicant's expression to police of a preference to be shot rather than be imprisoned. As to the planning of the first offence, it may be that that is not inconsistent with its being the product of mental illness. Moreover, one might question the effectiveness of the applicant's disguise when committing that offence in the presence of members of his family. As I have said, it did not prevent his daughter recognising him.
28 Nevertheless, a finding that the applicant's mental illness contributed to the offences would need to have been supported by expert evidence disclosing the basis upon which that finding was available. In his second report Dr Westmore did not elaborate at all upon his assertion of a link between the illness and the applicant's behaviour. His ability to proffer a basis for that opinion must have been hampered by the fact that the applicant declined to provide him with an account of the offences. Nor did the applicant give evidence in the sentence proceedings, and Ms Davenport was unable to take us to any part of his recorded police interview which might have provided a foundation for the doctor's opinion.
29 Ms Davenport referred to a passage in the Justice Health material from which it appears that the applicant told a health professional that he believed that Mr Mostafa was planning to sexually abuse his daughter. This appears in notes made on 12 July 2004, five days after his arrest. Nothing of the kind was suggested elsewhere in the evidence. In particular, he said nothing about it in his recorded police interview and there was no reference to it in Dr Westmore's reports or in his father's evidence. Nor is it referred to in his Honour's remarks and, indeed, it does not appear to have been raised at the sentence proceedings.
30 It is difficult to place any weight on this assertion, or to afford any significance to it. There appears to have been no material before his Honour by which it might be decided whether there was some factual basis for it, whether it was a fabrication or whether it was a delusional belief. Certainly, there was no evidence, expert or otherwise, to establish that it was engendered by mental illness.
31 Ms Davenport emphasised the fact that almost immediately after the applicant's arrest he was found to be suffering from a psychiatric condition, previously undiagnosed and apparently of long standing. She argued that this alone warranted a conclusion that his condition influenced the commission of the offences.
32 I must say that this aspect of the matter has troubled me. However, as I have said, the question of a link between the applicant's mental illness and his offences was a matter for expert evidence. Whilst acknowledging the undoubted expertise of Dr Westmore, his second report was wholly inadequate to establish that link. The bare assertion of a link, without elaboration, was insufficient: cf Makita (Australia) Pty Ltd v Sprowles (2001) 52 NSWLR 705. It was open to his Honour to find that the connection had not been established."
40This approach has been followed in a number of later cases (see for example Mercael v R [2010] NSWCCA 36 and Lewis v R [2011] NSWCCA 206).
41In this case there was no expert evidence that the applicant was suffering from a mental illness at the time of the offence, or as to any causal connection between the offence and the mental illness the applicant was later diagnosed to be suffering from. His Honour carefully considered the evidence, but concluded that it did not establish that mental illness was suffered at the time of the offence. That conclusion was plainly open. The evidence was not all one way, as was submitted for the applicant.
42If his Honour had come to the conclusion that a mental illness was suffered at the relevant time, he would also have had to consider the causal connection between the illness and the offence and whether the result should be the imposition of a lesser sentence, because the applicant's circumstances were such that the need for deterrence to feature in the sentence needed to be modified.
43While such a connection was not established, the mental illness which the applicant was suffering from at the time of sentence, was still a factor to be taken into account in determining sentence. That illness was taken into account by his Honour, who determined as a result that special circumstances existed, warranting a longer than usual non-parole period. In adopting that approach his Honour did not err.
44 Accordingly, this ground of appeal must fail.
