36 In R v Daetz; R v Wilson [2003] NSWCCA 216; 139 A Crim R 398 at [62], James J referred to the approach to be taken to an assessment of the weight of extra-curial punishment in the following way:
"62 I have concluded from this examination of the authorities cited to the Court and especially Allpass, Clampitt-Wotten and Cooney that, while it is the function of the courts to punish persons who have committed crimes, a sentencing court, in determining what sentence it should impose on an offender, can properly take into account that the offender has already suffered some serious loss or detriment as a result of having committed the offence. This is so, even where the detriment the offender has suffered has taken the form of extra-curial punishment by private persons exacting retribution or revenge for the commission of the offence. In sentencing the offender the court takes into account what extra-curial punishment the offender has suffered, because the court is required to take into account all material facts and is required to ensure that the punishment the offender receives is what in all the circumstances is an appropriate punishment and not an excessive punishment. How much weight a sentencing judge should give any extra-curial punishment will, of course, depend on all the circumstances of the case. Indeed, there may well be many cases where extra-judicial punishment attracts little or no significant weight."
37 In Mackey v R [2006] NSWCCA 254, in a factual context not dissimilar to this case, the Court concluded that the sentencing judge did not err in failing to take into account the injury suffered by the offender when the injuries did not result in a serious loss or detriment.
38 The evidence before her Honour as to the extent of injuries the respondent suffered at the hands of others was limited to photographs of the injuries and mention made in the report of Mr Watson Monroe, consultant forensic physiologist, of the respondent having reported to him that he was initially hospitalised at Royal North Shore Hospital with fractures to his eye sockets and broken ribs before being remanded in custody, and that he has suffered shoulder pain since that time which has been treated with an anti-inflammatory drug. In my view, consistent with the overarching principle to which James J refers in R v Daetz and Wilson, the respondent's injuries, whilst not wholly irrelevant, ought to have been afforded little weight in mitigatory terms.
Has error requiring re-sentence been demonstrated?
39 In recognition of the width of the discretion that is the legitimate province of the sentencing judge, this Court has sought to deter both the Crown and offenders from instituting proceedings where the primary challenge is to the weight afforded to competing considerations in a sentencing exercise. However, after a careful review of her Honour's reasons for sentence, I consider that her discretion has miscarried due to the unwarranted weight she gave to what she described as the severe summary justice the respondent suffered at the hands of others in mitigation of sentence and by her failure to give any account to the risk to public safety his conduct occasioned as a circumstance of aggravation. This, together with her Honour's erroneous appointment of the offending as below mid range, satisfies me that another sentence is warranted in law and ought to have been passed in accordance with s 6(3) of the Criminal Appeal Act. For this reason it is not necessary for consideration to be given to the Crown's further submission that her Honour was not entitled on the evidence to regard the respondent's prospects of rehabilitation as favourable or to find that he was unlikely to re-offend, since these matters will be given fresh consideration on re-sentence.
40 In undertaking that exercise this Court must exercise its own sentencing discretion and make its own assessment of the position the respondent's offence occupies on a scale of objective gravity and, since the respondent was convicted after trial, in accordance with the approach mandated by s 54B(2) and (3) of the Sentencing Act.
41 After taking into account all the circumstances of the offence including, inter alia, the weapon used to inflict the injury and the injury that resulted, and despite the matters that bear relevantly on the respondent's mens rea, in particular his state of intoxication and his motivation, I regard the offending as within the hypothetical mid range for offending of the kind for which s 33 provides criminal sanction. Accordingly, the standard non-parole period of 7 years is the appropriate starting point for the calculation of sentence and a sentence that should be imposed subject to s 21A of the Sentencing Act.
42 I have already expressed the view that the offending was aggravated by the fact that it occurred in a public place where there was a palpable risk to members of the public and that for sentencing purposes this displaces any consideration being given to the injuries suffered by the respondent as members of the public sought to disarm and contain him. The respondent is however entitled to the benefit of a positive finding in so far as his assistance to the authorities is concerned which, together with the utility that resulted from pre-trial disclosure as provided for in s 21A(3)(l) and (m), I am satisfied results in a compound discount of 20 per cent. This will be featured in the sentencing order I propose.
43 With a view to determining the mitigatory effect of other matters specified as under s 21A(3) of the Sentencing Act, namely the respondent's record, his prospects of rehabilitation and the likelihood of him re-offending and the effect of those matters on the standard non-parole period, it is necessary to consider the evidence both at the time of offending and currently, as it concerns those matters.
