The fact that the activity was a high risk or inherently dangerous sport is manifest from the nature of the sport, the activity described by the respondent, and his evidence establishing that he had frequently been involved in falls. He said "You could have up to a dozen falls in a day." He had not counted how many he had had in his career but he gave an estimate of more than 50 (p59 of black appeal book). The danger to a fallen rider in a motor cross race is inherently obvious, and notwithstanding his youth must have been and was obvious to the respondent from his participation over some years in many motor cross races.
34 Appellants' counsel particularly relied on the evidence of a warning which was given to the respondent by his father, Mr Anthony Ardizzone, before the race. Mr Ardizzone was familiar with motor cross racing and with the practice of stationing marshals, and his evidence, which the Trial Judge found to be reliable, was that he had acted as a marshal on the particular straight stretch where the accident happened on earlier occasions. Mr Ardizzone said in evidence (p.66 of black appeal book) to the effect that he had been involved in motor cross for many years before the accident took place, that he had seen a lot of falls and spills involving young motor cross riders at the age of the respondent and that serious injuries were very rare: "It's very rare for anyone to have a bad injury." This evidence supports what I have said about foreseeability and inherent danger.
35 Before the race began Mr Ardizzone was aware that no marshal was stationed on the straight section of the track and in his own mind wanted to leave and take his son home; he did not do so because his son did not want to go, and he left his son in the race for that reason. Mr Ardizzone said to the effect that there were three or four marshals at the race but not on the straight (see p.65 of black appeal book). In evidence he said:
A. Well it was my idea to stop him racing yes.
Q. Did you go up to the starting line and say 'Look Daniel you'd better not race, there's no marshal at the straight section' did you say that to him -
A. Absolutely, prior to him starting I did yes, I did.
Q. And he said 'Thanks Dad but no thanks, I'm continuing on', is that right?
A. Because as most children do, they beg you to stay.
Q. And you didn't say anything to any other official about it is that right?
A. No, well there isn't --
Q. You didn't say anything to any other official about your concern about a lack of marshals on the straight section is that right?
A. Not to an official no.
36 The locutions included in the cross-examiner's questions: "Look Daniel you'd better not race, there is no marshal at the straight section" and "Thanks Dad but no thanks, I'm continuing on" were not quotations from any other passage in the evidence. It was not suggested to the respondent in cross-examination that he had received a warning in those terms or in any terms. The issue about the warning had its origin in Mr Ardizzone's evidence to the effect that the respondent did not want to leave, and that it was Mr Ardizzone's idea to stop the respondent from racing. If anything the tendency of cross-examination of the respondent had been to suggest that there were sufficient marshals. Accordingly the evidence of the respondent did not include any evidence dealing with whether or not he had had a warning from his father. There was no application to the Trial Judge to re-open cross-examination of the respondent to put this suggestion to him. How the Trial Judge would have responded to an application for leave to put this profoundly different suggestion to the respondent is not known; his Honour could well have reacted with surprise, but there was no such application.
37 Paragraph 37 of the Trial Judge's judgment which I have set out shows that his Honour reached the conclusion that the standard of care required the appellants to have adequate marshals at curves and jumps such as the one described by the respondent without making any reference to the warning given to the respondent by his father. From this I understand that his Honour did not regard the warning as having importance in assessing the standard of care.
38 I will spell out what I regard as establishing the standard of care. Like the respondent, participants in the race were not adults, but children. Participation was voluntary, and there was no context of school or other discipline. To participate a child needed equipment and support which could only be provided by a parent or a circle of supporting adults, for example supply and maintenance of motorcycles, and provision of more basic aspects of organisation such as attendance and arranging participation in races. The situation of the respondent, aided and attended by his father, must have been typical for participants. There were obvious risks of injury inherent in the sport, obvious even to a child of 12, relating to falling off a motorcycle and impact by another motorcycle. It was not practically possible for a race to take place without the race being organised by someone in a position of general control, at the basic level of providing the track, and more organically in controlling the starting of the race, recording results, identifying entrants in races, and establishing qualifications for participation in particular events, such as the age and experience of participants and the power of their motorcycles. The exercise of control affected all participants equally, whether or not their fathers pointed out to them the absence or insufficiency of marshals. The appellants themselves did not give the warning to the respondent about the absence of marshals or risks related to their absence. The fact that the respondent received a warning from his father was not within the knowledge of the appellants. The exercise of the appellants' control was uniform for all participants, warned or unwarned.
39 Provision and stationing of marshals were ordinary and usual arrangements in the exercise of control over races, required (in a general way) by the relevant public authority and requiring further attention in detail to the adequacy of the number of marshals, and to where they were stationed. Marshals were customarily stationed and equipped with yellow flags with which to make signals; and customarily did make signals where appropriate, such as when there were falls. Provision of marshals, in adequate numbers and at appropriate stations, could not remove all the risk inherent in the sport, but would, according to circumstances, tend to operate to reduce risks, to prevent risks from being realised, and to protect participants against injury. Provision of sufficient marshals would work for the protection of all participants. Of overriding importance is that the participants were children, not mature in years or judgement, that although they were exposed to foreseeable danger and were able to appreciate and respond to risks, they were not able to do so, even if warned, in the same way as adults. The respondent had no means of control over events, other than to refuse to participate. No one could expect a good assessment of risk and a good decision on whether to participate in a motor cross race from a boy of 12.
40 Whether provision of sufficient marshals was a reasonable response to the foreseeable risk of injury is very largely answered by the consideration that it was the usual response. The test for adequacy of numbers of marshals is obvious enough; the track must be under observation, and the number and stationing of marshals must make this possible. In my view knowledge of the respondent that there was no marshal in the straight section does not have a prominent claim for consideration when assessing what was the standard of care imposed upon the appellants in the circumstances. The standard of care is not established by the understanding or response of a child. Treatment by the Trial Judge of the standard of care as extending to providing a marshal with a view of the straight and the jump and in a position to intervene if a participant fell off is the plain and obviously correct conclusion, and the presence or absence of a warning by the father of a particular participant does not have any significant part in determining the scope of the appellants' duty.
41 In my opinion the Trial Judge's assessment of the standard of care in paras 36 and 37 in his Honour's judgment is correct.
42 It was secondly submitted that if it was a breach of duty for the appellants not to have arranged the presence of a marshal, it was for the respondent to prove that the absence of a marshal was causative of the respondent's injury, and that it could only have been causative if the presence of a marshal would have been able to stop the following rider from colliding with the respondent. In support of this counsel referred to the improbabilities of the respondent's estimate of the time interval between his falling off the motorcycle and being struck by the following rider.
43 However the force of the respondent's evidence is not its force to establish that the time interval was as long as he said, but its force to establish that there was a significant interval of time between the respondent falling off his motorcycle so as to lie winded on the track, and the collision. Collision by an immediately following rider would have been no more than the realisation of an obvious inherent risk of the sport. Collision after a significant interval, that is an interval long enough for the marshal to observe the fall, signal with the flag and for the following rider to react, was the real object of proof.
44 Acceptance that there was a significant interval between the respondent's fall and his being hit was of central importance. If there was a significant interval, even only a few seconds, there was an opportunity for a marshal who was in a position to observe the fall to intervene, and if the marshal intervened by signalling to following riders with a yellow flag, it should reasonably be found to be probable that the collision would have been avoided. That is what marshals were stationed on the track to do, and it is a fair inference that if there had been a marshal in a position to act he would probably have acted. It is a sound line of reasoning that if there was a significant interval between the two events, and if there was a marshal in position to intervene and to signal with a flag to other riders, the collision would probably have been prevented.
45 It was contended that it was incumbent on the respondent to call evidence which would establish that the absence of a marshal would have made any difference; and that the practical implication of this was that it was incumbent on the respondent to call evidence of the following rider so as to show that action by a marshal would have made a difference. It was contended that it was within the respondent's power to identify the following rider, as the respondent's evidence showed that he knew the rider's bike number and the club he came from. The substance of the submission was that the Trial Judge was not in a position to accept the respondent's evidence or to find or act on the basis that there was a significant interval, in view of what was said to be its strong inherent improbability, unless it was supported by the evidence of the following rider.
46 Evidence was given by Mr Peter Atkinson, a regular attender at motor cross racing and the parent of another boy who participated in the same motor cross race. Mr Atkinson gave evidence of a number of facts relating to the events of the day and the practice of stationing marshals, although he did not himself directly observe the collision. He said in evidence that the motorcycle which collided with the respondent was bike number 52, that the rider was a Wollongong rider; and Mr Atkinson said that he could find out his name by going back to the Wollongong Bike Club of which Mr Atkinson was a member. The respondent knew the bike number of the rider who was behind him and which club he came from. (p56 of black appeal book) He could not recall his name. He knew him only from meeting him and talking to him on the day of the event, and he had not met him at a prior event.
47 Appellant's counsel's submission was not based on Jones v. Dunkel (1959) 101 CLR 298, as there is no basis for thinking that the following rider was in the camp of the respondent or of either party. The respondent had some information on which inquiry to identify and call the following rider could be based, but that is not enough, in my view, to establish that the witness truly was available. For observations relating to the respondent's not having called the witness to have full force the appellants would have to show that the witness was not only identifiable and available, but was in a position to give admissible evidence. That does not appear simply from the fact that he was the following rider, as there is a need to establish whether he in fact made any useful observations, whether he had any recollection, and whether he would be a willing or co-operating witness. After all, he did collide with the respondent and cause him injury. The respondent proved a prima facie case with his own evidence, it was open to either party to seek out witnesses and call them, and what evidence the following rider could give was at least as open to investigation by the appellants as it was to investigation by the respondent.
48 In my view there is no real force in the contention that, in the absence of evidence of the following rider, the respondent's case should not have been accepted. It should not in my opinion be concluded that the Trial Judge acted unreasonably, or was wrong in acting on the respondent's evidence in the absence of evidence of the following rider, or of any other rider in the event. Indeed there was no other witness in the whole of the evidence who spoke of seeing the event at all, and it is to some degree speculation whether or not the following rider was in a position to give evidence of value.
49 The Trial Judge concluded "… in the circumstances of that jump a marshal should have been able to see the jump and be able to warn the following riders if a fall occurred." Necessarily involved in that conclusion is the view that there was in fact an adequate interval between the fall and the collision for the marshal to give a warning, and the view that if a warning had been given, it would probably have been effectual. This conclusion disposed of the issue of causation. The conclusion has not been shown to be wrong.
50 The appellant's counsel thirdly submitted that the Trial Judge was in error in his treatment of the respondent's claim for damages for economic loss, and in his Honour's assessment of those damages. It was contended that the his Honour did not comply with s 13 of the Civil Liability Act 2002, and that the reasons given did not indicate that the steps indicated by s 13 were followed at all, or that they were followed in the appropriate order. It was contended that the Trial Judge did not recognise that the respondent had provided no evidentiary foundation to make and state the assumptions referred to in s 13. It was contended that the insufficiency in evidentiary foundation should lead to an order for a new trial as to damages; and that the new trial should be at large and not just on the issue of economic loss.
51 It is clear that the Trial Judge adverted to the relevance and operation of s 13, as submissions relating to s 13 were referred to in the judgment. In para.66 of the Trial Judge's judgment, His Honour recorded the contention by the appellants' counsel that the evidence was inadequate and that the Court would be forced to find that s 13 had not been met. The Trial Judge said (paras.67 and 68 of p.45 of red appeal book):
67. In my opinion this is a case for a cushion or buffer, the reason for this is that the plaintiff has shown that he has a restricted earning capacity in various occupations that he might have pursued has he not been injured. He has been restricted in the ability to be able to perform tasks requiring heavy manual work, this is something that he may well have had to pursue during the course of his life, even if he was able to obtain other types of work. It is not uncommon in our society for people to work 2 jobs, one being an office job the other being a manual job. He is clearly restricted in many of these regards and there is a likelihood as time goes on that he will have osteoarthritic changes affecting his ability to be able to perform his work.
68. In my view a proper assessment of his loss for the future taking into account his other injuries should be $100.00 per week. The plaintiff is now almost 19 years old. To age 65 he has 46 years. The multiplier for 46 years on the 5 percent table is 956.1. if one allowed the plaintiff $100.00 per week this figure comes to $95,610.00. Because of his other injuries and disabilities some slight reduction over and above the usual 15 percent vicissitudes should be allowed and I consider this should be 20 percent. I accordingly consider it is appropriate to allow him $75,000.00 for reduced earning capacity, being a rounded off figure applying generally the figures to which I have referred. There was no claim for lost superannuation entitlement.
