47 His Honour discussed at length during the remarks on sentence the limitations underlying much of the expert testimony. Ultimately, his Honour concluded that the difficulties inherent in the use of a less than accurate plan and the interpretation of the various marks left on the bitumen and the shoulder of the road tended "to undermine much of the central opinions expressed by each of the experts, particularly as to issues of speed at various points, the degree and process of retardation of the vehicles, and the extent to which there was significant braking and at what point it became effective." His Honour then turned to consider the level of the respondent's moral culpability on the basis that "his manner of driving was dangerous in the sense in which that expression is used in the section, but that the nature of dangerous driving in this case was that he was momentarily or briefly inattentive of his need to steer and drive his vehicle carefully on the road."
48 After referring to the Crown's written submissions, his Honour acknowledged that there were four factual matters upon which the court "would be prepared to sentence". Those factual matters were :-
(i) the Toyota was in lane one westbound at all pertinent times ;
(ii) the truck was exceeding the speed limit as it travelled down the hill
(iii) the area of the impact was some distance from the southern fog line
(iv) the prospect of locking brakes in an unladen semitrailer such as that driven by the respondent on a damp road is higher ; therefore more care is required in those situations and exceeding the speed limit is more dangerous.
49 On the question of speed, his Honour said that there was
no doubt that the offender was exceeding the speed limit which required him, as a truck driver, to be driving at no more than 40 km per hour. His own estimate was that he was travelling around 50 or a little bit more than that at the time he came down the hill and was in about ninth or 10th gear. The requirement, by law, was that he was not only to remain at a speed less than 40 km per hour but that he was to maintain that speed without the use of the foot brake in the truck.
50 His Honour then proceeded to canvass the "significant issue as to the actual speed." Following a review of the evidence, his Honour said :-
I am not satisfied beyond reasonable doubt that the offender was travelling at any more than 50 km per hour or thereabouts at the time he left the eastbound carriageway , nor is the evidence sufficiently cogent to establish beyond reasonable doubt that the use of the ninth or 10th gear was a factor which contributed to his losing control of the vehicle or driving off the eastbound carriageway of the road. It was obviously insufficient to provide exhaust braking which would bring him within the legal road limit, but whilst that obviously involves a breach of the appropriate regulations, it does not, in the circumstances of this case, establish that his speed was excessive in the sense that it was an unsafe speed for him to travel at in those conditions with a lightly laden trailer on that particular day . In other words, the court must proceed to sentence on the basis that the momentary inattention occurred at a time when the vehicle was being driven at a speed which it could not be said beyond reasonable doubt was itself dangerous and contributing to the vehicle driven by the offender leaving the eastbound carriageway and ultimately coming into collision with the vehicle driven by the deceased.
51 The first finding highlighted in bold above is against the weight of the evidence. It was never submitted by anyone, least of all the respondent's counsel, that the truck left the roadway at no more than 50kph. The most generous estimate for the respondent was 60kph (see [36] and [37] above). The second finding highlighted in bold builds upon the first and incorrectly assumes that an excessive speed must necessarily be found to be an unsafe speed before the case can be characterised as one involving more than momentary inattention. Even assuming a speed of 50kph, I fail to see how it could not be both excessive and unsafe, given that the respondent left the road. The same observations set out at [40] and [41] above apply to these findings.
52 After enumerating all of the aggravating factors in Whyte, his Honour found that none of them applied to the respondent and that therefore, it could not be said that he had abandoned responsibility for his conduct. Ultimately, his Honour assessed the moral culpability of the respondent "towards the lower end of that scale."
53 It is important to return to what was said by the Chief Justice in Jurisic in order to understand the ambit of "momentary inattention". The first reference to "momentary inattention or misjudgement" in Jurisic at 223 derives from R v Guilfoyle (1973) 57 Cr App R 549 at 552. There, the distinction was drawn between cases falling into two broad categories, namely, momentary inattention and "those in which the accused has driven in a manner which has shown a selfish disregard for the safety of other road users."
54 The Chief Justice in Jurisic also referred to R v Musumeci (unreported) NSWCCA 30 October 1997, which was "in many respects .. a guideline judgment". Following the introduction of s 52A, which almost tripled the maximum penalty formerly applying to this offence, Hunt CJ at CL in Musumeci summarised the considerations to be taken into account on sentence. In the course of that summary, his Honour said that where "the offence is committed even though the offender has had no more than a momentary or casual lapse of attention, there must always be room for a non-custodial sentence,….. but the case in which a sentence other than one involving full-time custody is appropriate must be rarer for this new offence." (bold not in original)
55 Consistent with this formulation, the guideline promulgated by Jurisic characterised non-custodial sentences for an offence against s 52A as "exceptional and almost invariably confined to cases involving momentary inattention or misjudgement". Whilst the Chief Justice did not say "no more than momentary inattention", it is implicit, in my opinion, from the references to Guilfoyle and Musumeci. (See also R v Howland [1999] NSWCCA 10 at [39] "mere momentary inattention" ; R v Dunlop [2001] NSWCCA 435 at [42] "more than momentary inattention") Next, and most importantly, the guideline went on to state that "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 of less than three years [in cases of death] … should be exceptional."
56 The aggravating factors involving the conduct of the offender are those set out in (iii) to (ix) at 231 in Jurisic, which include, relevantly for present purposes, the degree of speed, and the length of the journey during which others were exposed to risk. The presence of these factors were capable of indicating that the respondent had abandoned responsibility for his conduct, that is, that they were present to a material degree, and therefore exposed the respondent to a custodial sentence of at least three years, given that the matter went to trial.
57 Whilst it may be acknowledged that, in a relevantly similar case, the degree of speed might be so marginally above the applicable limit, and the length of the journey during which others are exposed to risk might be so brief, that the offender cannot be said to have abandoned responsibility for his or her conduct (see R v Bailey [2001] NSWCCA 10), that was not this case. The respondent acknowledged that he was familiar with the road, that he was aware of the danger inherent in driving a semi-trailer above the applicable speed limit down a steep gradient on a wet road, and that at no stage during his descent from the top of the hill (a distance of approximately 500 metres) did he comply with the relevant speed limit.
