Was the sentence imposed by the sentencing judge manifestly excessive?
59 In the course of his written submissions the appellant referred to the decision of this Court in R v Trevenna (2003) 149 A Crim R 505 where at 516 [41] Santow JA noted that
"the difficulty of attributing a meaningful sentencing range, where 'of all crimes, manslaughter throws up the greatest variety of circumstances affecting culpability'. "
60 In his judgment in the same case, Barr J said (at 530) (omitting case references)
"97. So variable is the crime of manslaughter, both in its legal formulation and in the range of culpability that it contemplates, that the identification of the available range of sentence in any individual case is notoriously difficult. In R v Blacklidge Gleeson CJ, with whom the other members of the court agreed, said:
'The crime of manslaughter comprehends all forms of punishable homicide other than murder ( Crimes Act 1900 (NSW), s18). For presently relevant purposes, the crime of murder is taken to have been committed where the act of the accused, causing death, was done with intent to kill or inflict grievous bodily harm, or with reckless indifference to human life. Some forms of manslaughter, such as that with which we are presently concerned, involve conduct which would amount to murder, except for the presence of some recognised mitigating circumstance. Other forms of manslaughter, sometimes referred to as 'involuntary', do not involve an intent to kill or inflict grievous bodily harm, or reckless indifference to human life. They may, for example, involve causing death by an unlawful and dangerous act. It has long been recognised that the circumstances which may give rise to a conviction for manslaughter are so various, and the range of degrees of culpability is so wide, that it is not possible to point to any established sentencing tariff which can be applied to such cases. Of all crimes, manslaughter throws up the greatest variety of circumstances affecting culpability.'
98. Another difficulty concerns the use by way of argument of the facts and resulting sentences in cases unrelated to the case under appeal. It is sometimes put that the facts of the case under appeal and those of the case cited for comparison are so alike that the sentences, too, should have been alike. Since they were not, error must have occurred. Hunt CJ at CL warned against such an approach in R v Morgan when he aid (at 371):
'It is quite wrong to compare the sentence under challenge directly with that imposed upon another offender (who is not a co-offender) simply because the two offenders may have similar characteristics and may have committed similar crimes. What must be looked at is whether the challenged sentence is within the range appropriate to the objective gravity of the particular offence and to the subjective circumstances of the particular offender, and not whether it is more severe or more lenient than some other sentence (other than that of a co-offender) which merely forms part of that range. As Mason J said in Lowe v The Queen:
"the reference to an appropriate sentence is apt to be misunderstood. Generally speaking, a sentence within a limited range of years is appropriate to the circumstances in which the offence was committed and to the character, antecedents and conditions of the offender. As the ascertainment and imposition of an appropriate sentence involve the exercise of judicial discretion based on an assessment of various factors it is not possible to say that a sentence of a particular duration is the only correct or appropriate penalty to the exclusion of any other penalty." '
99. When speaking of ranges of culpability and sentence counsel seem to have assumed that there must be a precise correlation between the two. While no doubt offences of high culpability ought to attract high sentences and those of low culpability low sentences there need be no precise correlation between sentences in unrelated cases where the facts are similar. Sentencing is an art. Sentencing judges have to evaluate a mass of evidence and different judges evaluate differently. Even if it were possible to say that the culpability in two unrelated cases was the same, it would not be correct to say, if the sentences were different, that for that reason alone one of them must be wrong. To say so would deny the existence of judicial discretion.
100. The statement of Hunt CJ at CL in R v Morgan is of general application but is particularly pertinent to manslaughter sentences for the reasons explained by Gleeson CJ in Blacklidge. … "
61 To similar effect, in R v Forbes [2005] NSW CCA 377, Spigelman CJ, with whom McClellan CJ at CL and Hall J observed (omitting case references):
"133. As has frequently been stated, manslaughter is almost unique in its protean character as an offence. (See in particular the observations of Gleeson CJ in R v Blacklidge ). In its objective gravity it may vary, as has been pointed out, from a joke gone wrong to facts just short of murder ( R v Weinman ; R v Hoerler ).
134. It is also relevant to recognise that, although manslaughters can be characterised in different ways, particularly in the various contexts which may reduce what would otherwise be a murder to manslaughter, the degree of variation within any such category is generally also over a wide range. Matters of fact and degree arise in all categories of manslaughter .
135. For example where diminished responsibility is relied upon, the extent to which culpability is 'diminished' can vary considerably from case to case. Similarly, although it is possible to characterise a number of cases as 'child-killing by a parent or carer', it may never be possible to identify a sentencing patter or tariff from the whole body of such cases. (See Hoerler ). This is not only because the number of cases in a particular category may be too few to establish a pattern or tariff. It is also because, within any such category, the relevant circumstances can vary over a wide range. This is also true in the case of manslaughter by reason of excessive self-defence ( R v Trevenna ).
136. The test established by s418 of the Crimes Act is whether 'the conduct is a reasonable response in the circumstances as he or she perceives them'. Such a test must depend on the characteristic and conduct of the deceased and also the nature of the response, in all of the circumstances of the particular case, on the part of the accused. A test of such a wide-ranging character is unlikely to lead to anything in the nature of a sentencing pattern or tariff in which the decisions on one case are of any particular utility for another."
62 In his judgment, Hall J (at [190]) recorded that the difficulty of establishing a sentencing pattern in cases of manslaughter had long been recognised. His Honour then set out an number of propositions on this point, which he derived from other judgments of the court. The gravamen of those propositions was that in the case of manslaughter it is peculiarly difficult to discern a range of commonly imposed sentences. Such sentences varied greatly because of the great variations in the circumstances of individual instances of the offence. Accordingly, it was erroneous to place too much store on any sentencing survey, let alone to look for a medium or average outcome: R v Morabito (1992) 62 A Crim R 82 at 86.
63 His Honour then set out a schedule of some nine cases to illustrate the point he was seeking to make. One of those analysed was R v Muddle [2004] NSWSC 403, upon which the appellant relied in the present case. The offender in that case was found guilty of manslaughter on the basis of excessive self-defence and was sentenced to six years imprisonment with a non-parole period of three years. Factors taken into account by the sentencing judge were that the offender had reasonable prospects of rehabilitation and was unlikely to re-offend, that the weapon was a household implement used in self defence, and that the offender had not previously served a period of imprisonment and had committed previous offences but not such as to be regarded as an aggravating factor. It was submitted that there were similarities between that case and the present sufficient to justify the submission that the sentence imposed by the trial judge was manifestly excessive.
64 The circumstances in which a court of criminal appeal can intervene to increase or reduce a sentence upon manifestly excessive or manifestly inadequate grounds were discussed by the High Court in Dinsdale v The Queen (2000) 202 CLR 321. In their joint judgment, Gleeson CJ and Hayne J said (at 325 [6]) that
"Manifest inadequacy of sentence, like manifest excess, is a conclusion. A sentence is, or is not, unreasonable or plainly unjust; inadequacy or excess is, or is not, plainly apparent. It is a conclusion which does not depend upon attribution of identified specific error in the reason of the sentencing judge and which frequently does not admit of amplification except by stating the respect in which the sentence is inadequate or excessive. It may be inadequate or excessive because the wrong type of sentence has been imposed (for example, custodial rather that non-custodial) or because the sentence imposed is manifestly too long or too short. But to identify the type of error amounts to no more than a statement of the conclusion that has been reached."
65 Furthermore, Gaudron and Gummow JJ (at 329 [22]) observed that the question before the Court of Criminal Appeal (from which the appeal to the High Court had been brought) was whether, in terms of House v The King (1936) 55 CLR 499 at 505, the result reached by the trial judge had been
"upon the facts … unreasonable or plainly unjust [so that] the appellate court may infer that in some way there has been a failure properly to exercise the discretion which the law reposes in the court at first instance. Was the sentence 'manifestly wrong?' "
66 In his judgment, Kirby J (at 339 [57]) cited the following passage from the judgment of the High Court in Lowndes v The Queen (1999) 195 CLR 665 at 671-672 [15] where the Court remarked that
"a court of criminal appeal may not substitute its own opinion for that of the sentencing judge merely because the appellate court would have exercised its discretion in a manner different from the manner in which the sentencing judge exercised his or her discretion …The discretion which the law commits to sentencing judges is of vital importance in the administration of our system of criminal justice."
67 Kirby J then continued (at 339-340):
"58. Because the imposition of a sentence involves the exercise of judgment and evaluation upon which minds can differ, it bears close similarities to the making of a discretionary decision. Like such a decision, if properly imposed, a sentence will not be disturbed on appeal merely because the appellate court would have reached a different result had the responsibility of sentencing belonged to it. As in the case of appellate review of a discretionary decision, a brake is imposed upon undue appellate disturbance of primary decisions (an unwarranted appeals seeking that relief) by the necessity to identify an error that justifies and authorises appellate intervention. Such an error may involve the adoption by the primary judge with incorrect principle, giving weight to some extraneous or irrelevant matter, failing to give weight to some material considerations or a mistake as to the facts: House v The King (1936) 55 CLR 499 at 505.
59. As on appeal from discretionary decisions, it will sometimes not be possible to identify, with exactness, an error of the foregoing kind; yet the result that is challenged may be so manifestly unreasonable or plainly wrong that the appellate court would be able to infer that, in some identified way, there has been a failure to exercise the power properly. In appellate review of sentencing, it will commonly be the case that the appellate court's authority to intervene would derive from the conclusion that the resulting order is so disproportionate to the matter to which it relates as to afford the foundation for concluding that, in some way, the exercise for the powers of the primary judge has miscarried.
60. The existence of this residual basis for appellate intervention is well-established. In fact, it is inherent in the provision by statue of a facility to appeal against sentence to a court of criminal appeal. It enables such a court to correct 'idiosyncratic views' of it individual judges about punishment for particular crimes and types of crime and replace a sentence that is manifestly disproportionate in the circumstances. Such disproportion can arise where the punishment imposed is considered to be plain excessive."
68 In Markarian v The Queen (2005) 79 ALJR 1048 Gleeson CJ, Gummow, Hayne and Callinan JJ in a joint judgment observed at 1055 [25] as follows:
"As with other discretionary judgments, the enquiry on an appeal against sentence is identified in the well-known in the joint reasons of Dixon, Evatt and McTiernan JJ in House v The King , itself an appeal against sentence. Thus is specific error shown? (Has there been some error of principle? Has the sentencer allowed extraneous or irrelevant matters to guide or affect the decision? Have the facts been mistaken. Has the sentencer not taken some material consideration in account?) Or if specific error is not shown, is the result embodied in the order unreasonable or plainly unjust? It is this last kind of error that is usually described, in an offender's appeal, as 'manifest excess', or in a prosecution appeal, as 'manifest inadequacy'. "
69 Having noted that the passing of a sentence is a discretionary judgment, their Honours (at [27]) observed that
"As the bases for appellate review revealed, what is required is that the sentencer must take into account all relevant considerations (and only relevant considerations) in forming the conclusion reached. As has now been pointed out more than once, there is no single correct sentence. And judges at first instance are to be allowed as much flexibility in sentencing as is consonant with consistency of approach and accords with the statutory regime that applies."
