Consideration
63The nature of the sentencing task is to fix the appropriate sentence for the offence and the offender, having regard to all relevant facts, matters and circumstances. A sentence must fit the offending having regard to its objective seriousness; that is the offender must be adequately punished for his offending. At the same time, a sentence should not exceed what is proportionate to the crime.
64I bear in mind that the maximum penalty for manslaughter under s 24 Crimes Act 1900 (NSW) is imprisonment for 25 years. This not a case to which s 25A of that Act applies as the offending precedes its enactment. It would not apply anyway because of the offender's mental illness which is a significant cognitive impairment for the purpose of that provision.
65It goes without saying, I think, that no penalty other than a period of imprisonment is appropriate in this case.
66The starting point of assessing the objective seriousness of any case of manslaughter is the consideration that the offender by his violent conduct took a human life (Mundo v Western Australia [2013] HCA 38; 87 ALJR 1035 ([53] - [55]). The general rule is that it is necessary that violent offending be justly punished to vindicate the human dignity of the victim, to protect the community and to deter the offender and others. Mitigating factors must be given appropriate weight, but they must not be allowed to lead to the imposition of a penalty which is disproportionate to the gravity of the offence.
67The Court must eschew any attempt to put cases of manslaughter into preconceived categories. Such categories do not exist. Each offending must be assessed by reference to all of its circumstances.
68Moreover as the Crown submissions point out, at least on one level, this offending "called for the express and demonstrable application of the element of general deterrence as a powerful factor on sentence" (R v Loveridge [2014] NSWCCA 120). This followed because, as is clear from the facts as I have stated them, the offending in this case consisted of an unprovoked attack upon an unsuspecting and vulnerable member of the public, lawfully present on a public street by an offender intoxicated by too much alcohol and some cannabis. These considerations bespeak significant objective seriousness.
69In Loveridge (at [216] - [217]) the Court of Criminal Appeal said:
... the commission of offences of violence, including manslaughter, in the context of alcohol-fuelled conduct in a public street or public place is of great concern to the community, and calls for an emphatic sentencing response to give particular effect to the need for denunciation, punishment and general deterrence.....
General deterrence and retribution are elements that must assume greater importance when the crime in question is a serious one, has been committed in a particularly grave form and its contemporary prevalence is the cause of considerable community disquiet: R v Williscroft [1975] VR 292 at 299.
70In R v MD [2005] NSWCCA 342; 156 A CrimR 372 at 387 [65], the Court of Criminal Appeal said:
In many cases where an offender is convicted of manslaughter there will be exculpatory matters and personal circumstances that can lead the court to significantly ameliorate the sentence which might otherwise be imposed. However, as this Court pointed out in R v Troja (unreported, CCA 16 July 1991) it is important for the court to ensure that the subjective circumstances of an individual offender do not divert the court from imposing a sentence which adequately reflects the part which the law must play in upholding the protection of human life and in punishing those who take it.
71However, the difficulty in this particular case, as the Crown submissions also recognised, is the part played by the offender's undoubted psychiatric illness. This consideration distinguishes this case considerably from cases involving manslaughter by dangerous and unlawful act where an offender has set out to either wreak havoc, engage in affray or give vent to a violent self-gratification.
72The purposes of sentencing, and the principles which inform them, "overlap". And as "guideposts" they "sometimes ... point in different directions" (Veen v the Queen (No 2) [1988] HCA 14; 164 CLR 465 at 476).
73The need for emphatic justice in the present case must be ameliorated to a degree by the offender's undoubted psychiatric illness, which in large measure, but not solely, accounts for his offending. I accept his intoxication and his non-compliance with his medication also played a, somewhat lesser, part. His experience of his illness would have made him aware of the effect of cannabis on his symptoms and that his symptoms would be worse if he was non compliant with medication. But one cannot expect a person with schizophrenia to be completely rational.
74There are certain well recognised principles that come into play when sentencing a person suffering from mental illness, especially where as here, the mental illness was a significant cause of the commission of the offence. In such cases, the impairments arising from the mental illness substantially reduce the offender's moral culpability for the offence.
75I am conscious that this offender's criminal liability has been reduced by his reason of his substantial impairment, but his condition continues to have relevance for sentencing purposes. Moral culpability, as distinct from legal liability, is an issue of particular relevance in sentencing (see Chung). Moreover, "the retributive effect and denunciatory aspect of a sentence that is appropriate to a person of ordinary capacity will often be inappropriate to the situation of [a mentally ill] offender and to the needs of the community." Muldrock v the Queen [2011] HCA 39; 244 CLR 120 at 139 [54]. Additionally, it is well recognised that general deterrence should "often be given very little weight" in the case of the mentally ill "because such an offender is not an appropriate medium for making an example to others" (R v Mooney (unreported, Court of Criminal Appeal (Vic), 21 June 1978).
76The relevance of specific deterrence may also be diminished (R v Windle [2012] NSWCCA 222 at [41] - 42]).
77I recognise that the application of these principles relating to mental illness does not always lead to a lesser sentence than that which would be imposed upon an offender of ordinary capacity. (Veen No. 2 at 476 - 477; R v Engbert (1995) 84 A Crim R 67 at [71]). Sometimes an offender's mental illness will make him a particular danger to the community. This factor which may require a heavier sentence, proportionate to the offending, than that appropriate in the case of an offender of ordinary capacity. Moreover, in a given case, a need for specific deterrence of the offender may have a similar effect.
78It is the interplay of the principles discussed in Loveridge with these principles relating to the effect of mental illness which is most significant in determining the appropriate sentence in all the circumstances of the present case.
79There is no suggestion in the present case that the offender presents a particular danger to the public. True this offending occurred whilst he was at liberty conditionally. And that suggests a degree of disregard of the law. However, despite some aggression in his presentation when florid as disclosed by the past medical history, there is no history of actual violence and his criminal record as an adult does not suggest it. The bond was not imposed for a crime of violence. He has good insight and conducts himself well when he is compliant with medication.
80On the other hand, I accept that his mental illness does not eliminate the need for considerations of specific deterrence in the present case. That need is engaged by him breaching his bond and by his long history prior to this offending of non-compliance with his medication and the abuse of alcohol and illicit drugs, which contributed to his offending. From his knowledge and experience he should know that cannabis aggravates his symptoms.
81I accept his remorse is genuine and rehabilitation prospects are better than reasonable if he remains abstinent and compliant. I accept that his mental illness reduces his moral culpability, diminishes to a degree the emphasis on retribution for and denunciation of drunken violent offences in public streets, and greatly diminishes the utility of general deterrence in this case.
82Even so, it is necessary to impose a sentence "which adequately reflects the part which the law must play in upholding the protection of human life and punishing those who take it" (R v MD at [65]). The offender's mental illness plays a central part in significantly ameliorating the sentence which might otherwise be imposed. However, this amelioration only goes so far. It remains necessary to impose a sentence which reflects the serious objective circumstances of this offending.
83I think it appropriate to allow a 25 per cent discount on the sentence which would otherwise have been imposed to reflect the utilitarian value of the offender's offer to plead guilty to manslaughter at an early stage. But for this I would have imposed a term of imprisonment just shy of 11 years. This discount reduces the sentence to one of 8 years.
84I am required to fix a non-parole period reflecting the minimum term that justice requires the offender to serve before release into the community. It should not be thought that release at the expiration of the minimum term is a foregone conclusion. It will depend upon many things, including the offender's continued good conduct whilst in prison. The question of whether the offender will be released is not for this Court. It's a decision that will be made according to law by the appropriate branch of the executive government in due course.
85There is a statutory relationship between the head sentence and non-parole period which may only be varied by a finding of special circumstances. To establish special circumstances, the offender relies upon the opinion of Dr Nielssen that a longer period of parole in the offender's case may be protective against relapse to substance abuse and non-compliance with treatment. On the other hand, Dr Nielssen assesses the offender's prospects of adhering to treatment and abstinence favourably. Moreover, as the Crown argue, the statutory ratio is likely to provide a long period of supervision in the circumstances of this case in any event. I accept this submission. In all the circumstances of the present case, I am not persuaded that a longer period is necessary and accordingly special circumstances have not been made out. The non-parole period will be 6 years and I will backdate the sentence to 3rd April 2012 to take account of fulltime custody served whilst awaiting trial.
86Michael McKnight, by its verdict the Jury convicted you of the manslaughter of Stafford David Ray on 25th March 2012. I sentence you to a term of imprisonment having a non-parole period of 6 years commencing 3rd April 2012 and expiring on 2nd April 2018 with an additional term of 2 years commencing on 3rd April 2018 and expiring on 2nd April 2020. The first date upon which you will be eligible for release on parole is 3rd April 2018.
