21 Many of the factors relevant to sentencing in a case such as this were adverted to by Hunt CJ at CL in Alexander (1994) 78 A Crim R 141. Particularly because both victim and offender and their families are foreign or of foreign extraction, it may be appropriate to repeat them:-
"The sentence to be imposed for any crime must take into account the many different purposes which that sentence is expected to serve - the protection of society, personal and public deterrence, retribution and reform. But, as the High Court in Veen (No. 2) went on to point out:
"The purposes overlap and none of them can be considered in isolation from the others when determining what is an appropriate sentence in a particular case. They are guideposts to the appropriate sentence but sometimes they point in different directions."
In the present case, I am satisfied that there could be no concern for the protection of society, and no need for personal deterrence or reform, so far as this prisoner is concerned. I am satisfied that he is never likely to react in this way again.
It is nevertheless always important in seeking to determine the sentence appropriate to a particular crime to have regard to the gravity of the offence viewed objectively, for without such an assessment the other factors requiring consideration before arriving at the proper sentence to be imposed cannot properly be given their place. Except in well defined circumstances such as the youth or the mental incapacity of the offender, public deterrence is generally regarded as the main purpose of punishment, and the subjective considerations relating to the particular prisoner (however persuasive) are necessarily subsidiary to the duty of the courts to see that the sentence which is imposed will operate as a powerful factor in preventing the commission of similar crimes by those who may otherwise be tempted by the prospect that only light punishment will be imposed. Retribution, or the taking of vengeance for the injury which was done by the prisoner, is also an important aspect of sentencing. Not only must the community be satisfied that the offender is given his just desserts, it is important as well that the victim, or those who are left behind, also feel that justice has been done.
The tensions involved in the imposition of the appropriate sentence in a provocation case - where necessarily there has been at the same time both a loss of self control and an intention to kill or to inflict grievous bodily harm - were discussed by the former Chief Justice, Sir Laurence Street, when speaking for the Court of Criminal Appeal in 1981, in a passage which bears quotation in full:-
"The circumstances leading to the felonious taking of human life being regarded as manslaughter rather than murder can vary infinitely, and it is not always easy to determine in any given case what should be done in the matter of sentence. At the start it should be recognised that the felonious taking of a human life is recognised both in the Crimes Act 1900 (NSW) and in the community at large as one of the most dreadful crimes in the criminal calendar. The courts have, however, over the decades gradually manifested a willingness to recognise factual contents which provide some basis for understanding the human tragedies that can lead to the taking of a life. The manifestation of this humanitarian tendency is necessarily attended by the utmost caution. It can be seen to be constantly written in the decisions of the courts and in the enactments of the legislature that the taking of a human life is a grave action calling for a correspondingly grave measure of criminal justice being meted out to the guilty party.
In a case such as the present, where there is material justifying a degree of understanding and of sympathy towards the appellant, the task of sentencing is particularly difficult. It is necessary to evaluate the demands of the criminal justice system, the expectations of the community at large, the subjective circumstances of the person coming forward for criminal judgment and the interest of society in protecting itself and its members from criminal activity amounting, as in the present case, to the taking of a life."
22 Alexander also indicates that attention should be directed to:-
" (i) the degree of provocation offered (or, alternatively, the extent of the loss of self-control suffered), which when great has the tendency of reducing the objective gravity of the offence;
(ii) the time between the provocation (whether isolated or cumulative in its effect) and the loss of self control, which, when short also has the tendency of reducing the objective gravity of the offence; and
(iii) the degree of violence or aggression displayed by the prisoner, which when excessive has the tendency of increasing the objective gravity of the offence."
