Ground 1: His Honour wrongly determined the applicant's moral culpability as high
27The applicant's counsel did not submit that the sentencing judge's factual findings concerning the offender's conduct were not open on the evidence. The focus of his submission was that those findings, in particular that the applicant was "showing off" and that the speed he was driving at was excessive, needed to be significantly tempered when assessing his degree of moral culpability, in part because of his Honour's related finding that the offences were not of the same gravity as offending which involved high speed travel along a public road and because the speed at which the applicant's vehicle was travelling was only marginally above the speed limit set by the owners of the private park.
28In Whyte, when considering the second limb of the guideline judgment in Jurisic, Spigelman CJ said the following:
[215] The second limb of the guideline in Jurisic at 231 was as follows:
"With a plea of guilty, wherever there is present to a material degree any aggravating factor involving the conduct of the offender, a custodial sentence (minimum plus additional or fixed term) of less than three years (in the case of dangerous driving causing death) and less than two years (in the case of dangerous driving causing grievous bodily harm) should be exceptional."
[216] I had earlier set out a list of aggravating factors which had been established in the authorities as follows:
"(i) Extent and nature of the injuries inflicted.
(ii) Number of people put at risk.
(iii) Degree of speed.
(iv) Degree of intoxication or of substance abuse.
(v) Erratic driving.
(vi) Competitive driving or showing off.
(vii) Length of the journey during which others were exposed to risk.
(viii) Ignoring of warnings.
(ix) Escaping police pursuit."
[217] Further consideration of the authorities would cause me to amend this list by changing (v) to read "erratic or aggressive driving" and adding:
(x) Degree of sleep deprivation.
(xi) Failing to stop.
[218] I went on to say at 231:
"Para(i) and para(ii) focus on the occurrence, whereas para(iii)-para(ix) refer to the conduct of the offender. The presence of these latter factors may indicate that the offender has abandoned responsibility for his or her own conduct. When the presence of such a factor can be so described, then it can be said to be present to a material degree for purposes of determining an appropriate sentence."
[219] It was after this passage that the two limbs of the guideline in Jurisic were set out.
[220] I said at 231 that the formulation of whether "the relevant aggravating factor manifest[s] in the circumstances of the case, that the offender has abandoned responsibility for his or her own conduct" involves an element of judgment on which sentencing judges could reasonably differ.
[221] I also said at 231:
"The period of three or two years, once the threshold of abandoning responsibility has been reached, is a starting point. The presence of additional aggravating factors, or their increased intensity, will determine the actual sentence."
...
[223] As set out above, the guideline in Jurisic was expressed in terms of an aggravating factor involving the offender's conduct being present "to a material degree". The factors identified all related to the moral culpability of the offender. The reference to 'abandonment of responsibility' was one formulation for describing a high degree of moral culpability. The case law subsequent to Jurisic does not suggest that it has been applied as if it were a statutory test.
29In my view, it was open to the sentencing judge to regard the combination of excessive speed (iii); showing off (vi); and ignoring warnings (viii) as constituting moral culpability of a high order. Although his Honour regarded driving at excessive speed in a private park as in a different category of offending to where drivers travel at excessive speed on a public road, as I see it, the critical finding supporting the assessment of a high degree of moral culpability was his finding that the applicant drove at excessive speed with the intention that the vehicle would become airborne and that it was this that led directly to the rear seat passengers suffering grievous bodily harm. It is an unexceptional observation that a safe speed depends upon a range of factors, including the posted speed limit and prevailing conditions. In this case, in my view, a safe speed had little to do with what private park owners considered might be an appropriate speed for recreational driving, or the fact that the applicant exceeded that limit by a relatively modest margin. To drive at a speed which was intended to launch the vehicle over the crest and into the air was dangerous on any view. I would also add that for my part, although his Honour gave the applicant the benefit of a finding that the consequences of driving over a sand dune at high speed might not be widely known, I regard the dangers inherent in driving a car (with or without a hard roof) under speed up and over a sand dune, with the intention that all four wheels leave the ground thereby depriving the driver of any control over the vehicle or how it might land, as obvious.
30Counsel also submitted that the significance of the concern expressed by the two passengers should be similarly tempered since the evidence was that this occurred immediately before the vehicle went over the sand dune and therefore at a time when there was nothing the applicant could do to heed the warning. This submission is contrary to the evidence summarised by his Honour and set out in [20] above.
31In considering whether there is error in the way his Honour dealt with the nature of the injuries and the degree of risk to others as aggravating features, it is necessary to set out that part of his Honour's sentencing remarks:
A number of aggravating factors were also suggested for consideration relating to the moral culpability of the offender.
I have mentioned repeatedly because of its importance in the sentencing decision the terrible injuries suffered by Ms Crawford. Mr Dailly concedes that it is an aggravating circumstance that more than one person was put at risk with Mr Stanyard driving over that dune with two girls in the back of his vehicle.
32I am persuaded that it was not open to his Honour to find that more than one person was put at risk because of the two young women in the rear seat of the applicant's vehicle and to treat it as an aggravating circumstance under the guideline judgment, whether in the assessment of moral culpability or as aggravating the occurrence of the offence. The applicant's trial counsel was in error in making that concession. In promulgating the guideline judgment in Jurisic, where the nature and extent of the injuries inflicted has been recognised as a discrete aggravating factor and where, as here, the suffering of grievous bodily harm is an element of the offence of dangerous driving, I am satisfied that the number of persons who may have been exposed to risk by the offender's dangerous driving must refer to people other than those identified as victims in the particulars of charge. Were it otherwise there is a danger of double counting and a corresponding risk that the sentence imposed will be excessive. In addition, even were there evidence of other park users being put at risk (which in this case there was not) this would not have been relevant to the moral responsibility of the applicant but rather to the consequences of his conduct (see [218] of Jurisic). The first ground of appeal is made out.
33However, in taking into account the extent and nature of the injuries that were sustained by Ms Crawford as an aggravating feature for the purpose of determining sentence on the count that concerned her (as his Honour was entitled to do under the guideline judgment), I am not persuaded that in the reasons for sentence or in the sentences imposed it is open to infer that those injuries were taken into account in the sentence imposed on the count involving Ms Free. To the extent that the applicant submitted that this was an additional basis for upholding the first ground of appeal, I would reject it.
