In those circumstances the level of the culpability of the offender is higher………………
18 The complaint before this Court is that his Honour ought not to have rejected the evidence of Dr Petroff based only upon the contents of the record of interview. As I have noted Dr Petroff was not called to give evidence and, therefore, was never in a position to comment upon the significance or otherwise of the statements made by the applicant to police as to his opinion as to the mental state of the applicant at the time of the commission of the offence. His Honour seems to have come to his view that he should reject the psychiatrist's opinions on the basis that they were inconsistent with the record of interview and expressed the conclusion that had the psychiatrist been aware of the contents of the interview he would not have formed the opinion that he did. But it was accepted by the parties that Dr Petroff had been in possession of the Crown brief, which included a transcript of the interview, on both occasions when he examined the applicant.
19 The applicant had the onus of proof in relation to the issue of his mental state at the time of the commission of the offence. Neither the psychiatrist nor the applicant was called to give evidence at the sentencing hearing. Yet I do not believe that the Judge was entitled to reject the psychiatric opinion for the reason that he did: that it was made without knowledge of the contents of the record of interview. I doubt that, without hearing from the psychiatrist, it was open for his Honour to find that the applicant's statements to police were necessarily inconsistent with his suffering from some abnormal mental condition, such as a Bipolar Disorder, at the time of the commission of the offence.
20 The record of interview was conducted four days after the commission of the offence. It was never suggested by the psychiatrist or the representative of the applicant at the sentencing hearing that the applicant did not appreciate what he was doing when he attacked his stepfather nor that he did not attack him as an act of revenge for the sexual assaults upon his sister. The submission was simply that because of his mental state at the time the applicant was less able to control himself, less able to think rationally about his conduct and, therefore, less culpable than might otherwise have been the case had he not been suffering a mental disorder. The fact that the applicant tried to make a joke about the dog having spoken to him might simply indicate that he was trying to mask his mental condition from the police. Dr Petroff noted in his second report that the applicant was reluctant to accept that he had a mental illness.
21 The Judge's rejection of the psychiatric evidence was a question of fact and this Court does not generally review such findings. But in this case it seems to me, with respect, that his Honour was not entitled to come to the conclusion that he did for the reason that he gave. Although this Court has also not heard from the psychiatrist, on all of the material, including the statements made by persons who had seen the applicant at the relevant time, I would find that it was more likely that the applicant was suffering from a mental condition that affected his culpability.
22 Although I believe the Judge was in error in his approach to the psychiatric evidence I would not intervene in light of s 6(3) of the Criminal Appeal Act. A sentence of 3 years with a non-parole of 18 months was in my view the most lenient sentence that the applicant could expect in light of the seriousness of the offence and even taking into account the fact that he was suffering from a mental condition at the time that no doubt affected his thinking and behaviour. The offence was a very serious example of conduct falling under s 35 both by reason of the nature of the assault and the injuries inflicted.
23 The Judge took into account that the applicant felt genuine anger against his stepfather for the alleged offences against his sister and that "while it is no excuse for what he did, it is perhaps understandable that he felt aggressive at a perceived lack of justice". In my view a Court cannot allow for any significant mitigation of the applicant's culpability because the offence was committed to punish the stepfather for allegedly interfering with the applicant's sister in light of the seriousness of the assault. Denunciation and general deterrence are very much to the fore when sentencing an offender who has taken the law into his own hands and inflicted serious injuries as retribution for wrongs allegedly committed by the victim. This approach must be taken in the present case notwithstanding that the applicant might have been suffering from a mental condition that influenced his conduct. It is not a case where in my view much weight can be given to the psychiatric condition to reduce the importance of general deterrence.
24 The Judge indicated that he was giving the applicant "full discount" for the plea of guilty. If he meant by that a discount in the order of 25 per cent, it was overly generous. The indictment is dated 11 October 2002, yet the applicant did not plead guilty to the lesser offence, a course that was always open to him whether the Crown would accept the plea or not, until 19 December 2003.
25 Notwithstanding the evidence placed before the Court for the purposes of re-sentencing the applicant, I do not believe that any lesser sentence than that imposed upon the applicant is warranted. The non-parole period in particular was a very lenient minimum period to be served and it is impossible to see how any lesser period of custody could reflect the seriousness of the offence committed.
26 I propose that leave to appeal be granted but that the appeal be dismissed.
