Sentencing
39 It has often been observed that manslaughter embraces a wide variety of human behaviour and a broad spectrum of criminality. Clearly, this case falls into the more serious category of that crime. The offender's attack upon the baby, although not attended by an intention to kill or to inflict really serious harm, was brutal. The child was the most vulnerable of victims, and the offender's relationship to him was effectively that of a stepfather. When the mother sought to protect him, the offender threatened her with a knife.
40 The killing was not an isolated incident. It was the last of a series of assaults upon the child, of escalating severity, over the preceding months. Indeed, on the night before the fatal incident he had inflicted violence of a broadly similar kind upon the baby, causing him to lose consciousness. It is, of course, a seriously aggravating feature that he was on parole at the time in respect of an earlier homicide.
41 That said, I accept that the killing was spontaneous, at a time when the offender had lost control of himself. Consistently with this, he promptly set about trying to revive the child by CPR, while the mother sought help through the emergency telephone line. He was disinhibited by alcohol but, clearly, his behaviour was largely the product of a propensity to impulsive violence characteristic of his personality disorder. This provides some explanation for the killing and for the earlier acts of violence, particularly in the light of the psychological stress to which he was subject over that period.
42 I take into account the offender's difficult and, at times, tragic background. Although that background is somewhat different from that of many Aboriginals from rural areas, examined by Wood J (as he then was) in R v Fernando (1992) 76 A Crim R 58, it raises the considerations set out by the former Chief Judge in that case. It seems that Greg James J took the same view when dealing with the offender for the previous manslaughter.
43 The trial of the offender for murder was scheduled to begin on 8 March 2010. However, several days were set aside to consider the admissibility of some evidence, and a jury was not empanelled at that time. The Crown prosecutor offered to accept a plea of guilty to manslaughter the following day, and the day after that the offender accepted that offer. As a result, a jury was not empanelled and a fairly lengthy trial was averted. I shall allow the offender a modest reduction of sentence for the utilitarian value of his plea.
44 There is no evidence of any expression of remorse by the offender, except so much as might be inherent in the plea of guilty. However, he is also entitled to some credit for the fact that his plea spared the mother and other members of the family from giving evidence in what would undoubtedly have been a distressing trial. In particular, it appears from the cross-examination of the mother at the committal proceedings that it would have been the offender's case that her evidence against him was fabricated, with the implication that she must have been the person responsible for the child's death.
45 Clearly, this is a case in which considerations of retribution, deterrence and the protection of society loom large. I must be guarded about the offender's prospects of rehabilitation, but I do not consider that there are none. Prior to the offence he had been at liberty on parole, without conflict with the law, for almost 2 ½ years. Nevertheless, the hope at the time Greg James J sentenced him that, with maturation and abstinence from drugs and alcohol, he would not re-offend has, tragically, been dashed. I cannot be confident that he would not again resort to violence in a stressful situation, but this makes it all the more important that he have the psychological support and the assistance in relation to substance and alcohol abuse recommended by Dr Westmore. The sentence I pass will provide for a lengthy period of parole eligibility, so as to foster his rehabilitation.
46 Since coming into custody he has been in segregation and, given the nature of his crime, it is likely that he will remain so for some time to come. I take that into account although, in the absence of any evidence as to the conditions of his custody as a result, I cannot give it much weight.
47 As I have said, he has been in custody since 7 November 2007 but was serving the balance of the sentence imposed by Greg James J until 18 December 2008. Nevertheless, counsel for the offender, Mr Hanley, submitted that I should backdate the sentence to the date on which the offender was charged with the murder of the child, 15 February 2008. I am not prepared to do that, but I think that the consideration of totality should be reflected in some measure of concurrency between the sentence I pass and the balance of the term previously imposed. I shall backdate the sentence to 18 June 2008.
48 Mr Hanley supplied me with a schedule of cases of sentence for child manslaughter, acknowledging that they could be of limited assistance only and could not be said to establish a tariff. There are thirteen cases, mostly decisions at first instance, decided over the last 10 years. Sentences range from 6 years with a non-parole period of 3 ½ years: R v Marshall [2003] NSWSC 448, to 10 years with a non-parole period of 6 years and 9 months: R v Compton [2008] NSWSC 204. As one would expect, the objective gravity of the offences dealt with in those cases varies considerably, as do the subjective circumstances of the offenders. However, it appears that none of those offenders was on conditional liberty at the relevant time, let alone for another homicide.
49 An additional case of importance, upon which I invited further submissions from counsel, is R v Hoerler [2004] NSWCCA 184, 147 A Crim R 520. That was a successful Crown appeal against the sentence passed upon the respondent for the manslaughter of a child, to which he had pleaded guilty. On re-sentence, the Court's starting point was imprisonment for 16 years, which was reduced by 10 % for the utilitarian value of the plea to 14 years and 4 months. Applying the statutory ratio, a non-parole period of 10 years and 9 months was fixed.
50 It will be seen that that sentence is significantly above the range disclosed by the other thirteen cases. Moreover, it was passed at a time when the principle of double jeopardy applied to re-sentence after a successful Crown appeal: see the leading judgment of Spigelman CJ at [70] ff. The significance of the decision is that the Chief Justice (with whom RS Hulme and Adams JJ agreed) examined factors bearing upon sentencing for the manslaughter of children by persons in a position of trust and responsibility and considered a number of cases, at first instance and on appeal, although his Honour concluded that they did not disclose a sentencing pattern for crimes of that kind: [47].
51 In Hoerler, the respondent had a criminal history which included some offences of violence, but nothing of the significance of the present offender's previous conviction for manslaughter. At the time of his offence he was on bail for a charge of burglary, that offence and other offences of a non-violent nature being taken into account by the sentencing judge on a Form 1: R v Hoerler [2003] NSWSC 1187, at [32]. This offence was an isolated incident. However, its objective gravity was significantly greater than the present case.
52 It is unnecessary to set out the detail of it, which is to be found in the judgment of the Chief Justice at [7] - [15]. It is sufficient to say that the child sustained a large number of injuries in the course of what his Honour described, on re-sentence, as a "prolonged, violent attack". He observed that the respondent's conduct included "dragging the body of the baby over a surface, such as a carpet or a sofa, face down causing a number of facial injuries", as well as "the gratuitous cruelty of an almost grotesque character by the application of clamps to both feet of the deceased baby … with sufficient force to break his toes": [66]. The sentencing judge found that the respondent was possibly affected to a significant degree by beer and cannabis at the time. Otherwise, the Chief Justice noted, there was no plausible explanation for the respondent's conduct and nothing that could mitigate his moral culpability: [67] - [68].
53 The difference between Hoerler and the present case is obvious. Grave as the present offence is, it was not exacerbated by the gratuitous cruelty, fairly described as torture, which characterised that respondent's crime. Nor is it devoid of any explanation arising from the offender's background, his psychological makeup and the circumstances in which he found himself at the relevant time. True it is that the offender's criminal history is much more serious and significant than that of the respondent in Hoerler. Nevertheless, it is clear enough that the primary focus in the re-sentence of that respondent was upon the objective gravity of his crime.
54 Ultimately, the sentence passed in Hoerler was one arrived at in the exercise of the Court's discretion, given the particular circumstances of that case. While the sentence I am about to pass is similar to that in Hoerler, it is the product of my assessment of all the circumstances, objective and subjective, peculiar to the present case. My starting point is imprisonment for 16 years. I shall reduce that by roughly 10% to 14 ½ years, to reflect the utilitarian value of the offender's plea of guilty. I find special circumstances, as the sentence is to be partly cumulative upon the balance of the term imposed by Greg James J, but the adjustment of the proportion between sentence and non-parole period will be minimal. The non-parole period will be 10 ½ years, leaving a period of parole eligibility of 4 years.
55 Accordingly, the offender is sentenced to a non-parole period of 10 years and 6 months, to commence on 18 June 2008 and to expire on 17 December 2018, and a balance of term of 4 years, to commence on 18 December 2018 and to expire on 17 December 2022.
