Plea of guilty
44 The plea of guilty for M.A. was entered on the first day of the trial. On the second day, Diab pleaded guilty to manslaughter. On one view, these pleas have come late in the proceedings. Nonetheless, the pleas did precede the voir dire (which would have included argument on the admissibility of the admissions of the offender to 'Jennifer') and the empanelling of a jury, and therefore a discount must be given on each sentence for the fact that the offenders have admitted wrongful conduct at a relatively early stage of the proceedings -indicating a willingness to facilitate the course of justice as well as, I am satisfied, some aspects of contrition: Cameron v The Queen (2002) 209 CLR 339. The utilitarian value of the plea must also be taken into account: see s 22 of the Sentencing Procedure Act; R v Sharma (2002) 54 NSWLR 300.
45 In line with the decision of the Court of Criminal Appeal in R v Thomson (2000) 49 NSWLR 383 an overall discount of 25 per cent will be given to each offender in the exercise of discretion in forming the appropriate penalty having regard not only to the utilitarian value of the plea, but also to contrition and the fact that the grief of the family would not be exacerbated by a trial.
The severity of a sentence
46 The offences of murder or manslaughter are very serious, involving as they do the loss of a human life. This murder has led to the loss of a young and promising life. Accordingly, the penalty must exhibit an appropriate severity so as to deter others from committing similar acts and to reflect the abhorrence of the community in relation to such conduct. These factors are best represented in fixing an appropriate head sentence. So much was suggested by the Crown and the Court accepts that this is an appropriate approach to the construction of the sentence: R v Simpson (2001) 53 NSWLR 704.
47 It must be recognised it is the head sentence that is the punishment imposed by the Court. It is in fixing this term that considerations of protection, deterrence and rehabilitation are taken into account to determine the appropriate punishment to be imposed.
48 The non parole period is, by comparison, fixed by statutory direction at 75 per cent of the head sentence. The Court is invested with a jurisdiction to decrease that period where there are 'special circumstances'. This discretion involves separate consideration of the offender's subjective circumstances and the two processes overlap. The non parole period must represent the minimum time that the offender should spend in gaol but it is not the time that the offender will spend in gaol. The non parole period represents a date that the offender may work towards so that if the promise of rehabilitation is shown to be well founded, he may be released at the expiry of that term at the discretion of the Parole Board. The question for them will depend upon the offenders' good conduct while in prison and evidence of contrition and rehabilitation. The Court has no power in relation to that issue.
49 The offence was irrational, stupid, immoral and without cause, and the offenders admit this fact. However, I will take appropriate account of the fact that M.A. had no prior criminal record and was therefore generally of good character: Ryan v The Queen (2001) 206 CLR 267. I also take account of the fact that M.A. was a child at the time of the offence, that is, he was of an age less than 18 years.
50 The offender was 17 years old at the time of the offence and therefore a child in accordance with s 3 of the Children (Criminal Proceedings) Act 1986 (NSW). This observation needs to be modified by referring to what was said by the NSW Court of Criminal Appeal in Voss [2003] NSWCCA 182. As the defence accepts, it is recognised that a young offender who conducts him or herself as an adult or engages in adult behaviour, best evidenced by some degree of planning or if the offence is of a serious and violent nature, the factor of youth and the prospects of rehabilitation becomes less prominent and more weight will be given to the objective seriousness of the offence: AEM (Snr) at [97]; MHH [2001] NSWCCA 161.
51 In the case of Mr Diab, the defence submits that cases of manslaughter by unlawful and dangerous act have a 'top of the range' at 10 years imprisonment: R v Bryant [1999] NSWCCA 181. I have difficulty in accepting that statement as a proper exegesis of what was said in Bryant. In that case the Chief Justice said of a sentence for manslaughter of six and a half years with an additional term of three and a half years:
…the sentence on this occasion can be seen to be a high one and perhaps towards the top of the range…
