The considerations to which I have referred indicate that a risk of injury which is remote in the sense that it is extremely unlikely to occur may nevertheless constitute a foreseeable risk. A risk which is not far-fetched or fanciful is real and therefore foreseeable. But, as we have seen, the existence of a foreseeable risk of injury does not in itself dispose of the question of breach of duty. The magnitude of the risk and its degree of probability remain to be considered with other relevant factors.
166 Carrera v Honeychurch (1983) 32 SASR 511 arose on facts with some similarities to the facts of the present case, although strikingly different in the respect that the rider was an adult; she had never ridden before, took part in a group ride organised by a riding school, and lost her seat and fell off when the horse made a sudden side-stepping movement. That the rider was an adult would be significant for any assessment of the capacity of the rider to exercise control over the horse: there may have been some justification for assessing the rider as having some capacity of that kind, whereas these could not, in my view, be any justification for such an assessment in relation to Tali Ohlstein. Passages which Ipp JA has set out show that there were significant differences of judicial opinion on duty of care. My own analysis has general similarities to that of Wells J at 524 of Carrera v Honeychurch, which Ipp JA has set out; but the facts are materially different.
167 Senior counsel for the respondents referred to Murray v Haringay Arena Ltd [1951] 2 KB 529 of which counsel said that the conditions of entry as a spectator to an ice hockey match for which the parent of the child agreed informed the duty owed by the occupier to the child. There were no express terms of the contract which the child's father made in paying for admission of himself and the child to premises as spectators of ice hockey. The ice hockey puck struck an infant spectator. Singleton LJ said at 533: "There were no express terms, and thus the liability of the defendants depends on the terms to be implied in the contract. I assume that the infant plaintiff is to be regarded as having entered into a contract with the defendants." The implied terms referred to do not appear to have influenced decision as his Lordship said at 534: "I am not sure that it matters whether it is called negligence or breach of the implied term to take reasonable care: in either event it is for the plaintiff to establish his case."
168 Singleton LJ referred to authorities relating to occupier's liability, including authorities relating to sporting contests and entertainments, decided on the basis of those authorities that "The implied term is to take reasonable care …" (at 536) and further decided that negligence had not been established. That was not a decision in which the duty of care to a child was modified by the terms of an agreement made by the parent.
169 In written submissions the respondents' counsel also referred to several decisions at first instance in Canadian Provinces relating to riding accidents none of which relate to facts closely analogous with the present case and none of which appear, in my respectful view, to establish any important principle.
170 The existence of duty of care and the question whether there was a breach are to be decided according to considerations which affect the respondents, Tali Ohlstein and the relationship between them; that relationship was not contractual, and could not be having regard to the child's age and understanding. The terms and the circumstances of the contractual relationship between the child's mother and the respondents do not in my opinion have any significant bearing on either the existence or on the breach of the duty of care owed to Tali Ohlstein. The child's mother was not in a position to alter, by contract or by any other arrangement, the considerations affecting whatever it was reasonable for the respondents to do with respect to risk of injury to Tali Ohlstein. Warnings given to Ms Duncan, by the display of signs at the respondents' premises or in other ways, could not in principle have any impact on the duty of care owed to Tali Ohlstein; nor could knowledge of risks involved in the activity which was given to Ms Duncan in any other way, or should otherwise have been obvious to her. There is no reason in principle why what Mrs Duncan accepted in the exercise of her parental responsibility should alter what was required by the respondents' duty of care to Tali Ohlstein; the respondents could not depute any part of their duty to Ms Duncan. The display of a sign disclaiming responsibility, upon which the respondents sought to rely in a Notice of Contention, can in a similar way have no effect on their duty of care to Tali Ohlstein, who cannot have had any understanding of the sign.
171 As with many recreations including those involving skill, an element of risk of injury is part of riding, and may even be seen as one of its attractions: Jorrocks, a 19th-century novel, spoke of hunting as having all the excitement of war and only a quarter of the danger. With riding as with other recreations negligence law relates to reasonable response to foreseeable risk, not to eliminating risk. It is beyond doubt that horseriding is a reasonable activity, that it must be learnt, that children as well as adults can learn it; and that with all reasonable care an element of risk remains. Knowledge of risk has a different place in a negligence case relating to an adult rider than it has in a case relating to a young child. Common knowledge and experience make it obviously open to consideration that there was negligence in conducting a trail ride in which a child of 5 1/2 years, who had no previous experience of horseriding, rode an aged and placid saddle horse without a lead rope. Much experience shows that it was unlikely that anything would go wrong, unlikely that the child would fall or that the horse would bolt. Perception of risk may well have been blunted for persons who were very familiar with the operation and the horse, who themselves were very adept at riding and had learned in their childhood, and who had seen the operation performed without mishap many times before.
172 Was it unlikely that something would go wrong and that the child would be injured? Was it reasonably foreseeable that something would go wrong and that the child would be injured? The two questions are quite different. The test of foreseeability is undemanding. The risk that the horse would make some movement which would unseat the child was, in my judgment, quite clear, even though it was unlikely that that would happen. Once it did happen, the means to control the event available in the respondents' system of operation were no more than that the leader would ride up to the horse and take control of it, or endeavour to do so: an uncertain exercise, and one which would not even start until there was a crisis. The entire inadequacy of this response to the risk is illustrated by the event which happened, in which the horse ran many metres and the child was dragged on the ground and suffered injury before the control took effect. As the operation was performed there was no useful available response to the risk. The means of response available were simple and obvious; the leader could have led the beginner rider, or several of them, while riding herself. This would not have eliminated the danger, but would have very greatly reduced the danger, and as a matter of probability (and not of certainty) would have meant that the sudden movement of the horse would have been brought under control much earlier than it was, and the child's fall and injury would have been averted.
173 Particular (t) can be understood at two levels. It was an aspect of the respondents' system of operation that a leader was equipped with and carried a lead rope with which a beginner rider could be led if some event happened during the ride and showed the leader that that was appropriate. This depended on the judgment of the leader in response to some event in the course of a ride. In this system of operation, no means were available to control a beginner's horse, other than whatever the beginner herself might be able to do and whatever may be achieved by attempting an intervention when some untoward turn of events presented itself. I do not think it is too blunt an observation to say that the safety of the beginner was left to the horse. The shortcoming of the system of operation is manifest.
174 The other level at which Particular (t) can be understood relates to negligence of leaders of trail rides in making the judgment which the respondents' system of operation left to them about whether and when it was appropriate to use the lead rope which they carried. The leaders Mrs Caruana and Ms Warriner operated within the respondents' system of operation, in which they were not to intervene and use the lead rope unless in the leader's judgment it was appropriate to do so; as a practical matter, unless some event precipitated decision. There was no event affecting Tali Ohlstein which could precipitate such a decision before the horse shied and galloped off in an uncontrolled fashion: there was one for Jared, who was not placed on a lead. When the conduct of the leaders is examined for acts or omissions of negligence in the course of their conduct of the trail ride nothing appears which calls for consideration. They conformed to their employers' system of operation. The leader attempted to control Tali Ohlstein's horse in response to the adverse situation when it arose, again in conformity with the employers' system of operation, in a situation where the availability of a lead rope could no longer contribute anything. I do not find it surprising, or important at all, that there was no cross examination charging either of the leaders with any act or omission of negligence in their conduct of events during the ride; I see no reason to think that a challenge of that kind could have had any substance. They accepted and operated within their employers' system of operation and appear to have regarded that as appropriate; the leaders cannot in my opinion be regarded as having been in breach of a duty of care.
175 The leaders were very well qualified, in experience and otherwise, for leading a trail ride; both had learned riding in childhood, one from the age of four and one from the age of five. There were no shortcomings in their experience or suitability for the work. They took care to choose appropriate horses and to fit each rider with the appropriate equipment; they also gave appropriate instruction, within the severe limits imposed by the business in hand. Ms Warriner made a careful selection of horses; with good reasons based on experience and knowledge of the horse she regarded Patch as a very safe horse. Ms Warriner gave careful instruction to the beginners including Tali, and gave Tali a second lesson. Although no doubt these preparations were carried out with skill and care and in a responsible way they cannot have done anything to equip a beginner child under six years of age to cope with a horse which became unruly; they cannot have done anything which made it reasonable to rely on the child's ability to do so.
176 Mr Lloyd had even more experience, 20 years involvement in activities at Otford Farm of which 17 years were full-time; he was engaged in the management of the business, and he had no experience of any injury to a person taking part in trail rides or other activities on Otford Farm. Mr Lloyd said in evidence that before Mrs Caruana left on the ride he asked her to take a lead rope, and gave this reason (Black 2/335) "I asked her to take a lead rope because the group was a mixed group, approximately half riders and half beginners. I sent the two guides so that they could split if necessary." There was a policy for use of lead ropes on the trail in relation to young beginner riders, in which it was in the discretion of the leader to use a lead rope held by a trail ride leader connected to the child's horse (Black 2/351). He gave several possible uses for the lead rope as well as leading a rider (Black 2/361). He said (Black 2/352):
Q. And in your mind what factors would you expect a trail ride leader to take into account in deciding whether or not to use a lead?
A. There would a number of factors depending on the size of the group, the riding ability of the group, whether they were all the same or whether it was a mixed group. It would also depend on whether the adult, whether there were other adults in the group that could lead their own children.
177 Mr Lloyd gave this evidence (Black 2/357-358):
Q. Are you saying that a young child beginner only needs the first five minutes to be able to develop those attributes?
A. I'm saying we can observe in five minutes how somebody is sitting and controlling the horse.
178 The ability of a child, assessed in five minutes, to control the horse in ordinary favourable circumstances is one thing; the ability to bring under control a horse which has begun to bolt or otherwise behave unexpectedly is quite another. In this passage Mr Lloyd made a claim of ability which is not entitled to acceptance, or to respect. Rather than treating this passage as assisting his case, I regard it as showing that his percipience of risk had been blunted by the absence of adverse outcomes from his own experience.
179 Mr Lloyd's evidence on the use of the lead rope also included this passage (Black 2/352):
Q. So all of those aspects would require assessment out on the trail, is that the position?
A. Often I have a parent who wishes to lead their own child and start with a lead rope at the start of the trail.
Q. And that is something that the parent raises with you?
A. Or we suggest to them.
Q. Now, when you suggest that to a parent, why is that?
A. In the first instance we ask the parent if they would like to lead their child on a pony in an enclosed area. If the parent decides that they are after a trail ride and we don't think the child is capable of fully understanding instructions or is a little nervous or hesitant, then the parent is offered a lead rope to lead their child if the parent is capable of doing so.
180 This passage should be understood with his earlier evidence (Black 2/335-336):
Q. Did you watch the group leave for any length of time?
A. Yes.
Q. What did you do?
A. I observed the start of the ride. I actually led Tali's horse out the gate and let go of Tali's horse and then observed them ride off.
Q. Why did you lead Tali's horse out the gate?
A. Often we need to lead one horse out of the gate just so the others will follow.
Q. When you led it out of the gates and let it go did you watch her at all?
A. Yes.
Q. How was she coping?
A. She was steering the horse and sitting correctly.
181 This seems to show that the system of operation was that Mr Lloyd made a judgment about whether a child should be led on the basis of his observations within five minutes of how a child was sitting and controlling the horse. The judgment was made by Mr Lloyd and not by Mrs Caruana or Ms Warriner.
182 Mrs Caruana's view of when a lead rope should be used was (Black 2/244):
Q. Was that a common experience for you prior to April 1998?
A. Not every child had to be on a lead. Either the mother asked for it or if they were under a certain age they had to be led, or sometimes at the pony club camps if they weren't confident enough or they couldn't control their horse or didn't know how to turn him or pull him up or something, then we'd put a lead on.
183 The system had, in all practicality, no means available to deal with the event that had happened, in which Patch moved to the side, Tali Ohlstein lost her balance, the horse ran off, Tali fell from the horse with her foot in the stirrup and was dragged for more than 100m, and suffered injury through falling, losing her helmet, being dragged by her leg and being struck by the horse's legs. The foreseeability of an event of this kind was altogether clear, and no response was available which could deal with it in any effective way. The absence of actual adverse experience in which this risk matured at Otford Farm appears to me to have little significance in the circumstance that the risk was clearly foreseeable in the application of the undemanding test of foreseeability, the injuries which could be sustained if the risk matured include extremely severe injuries, exemplified by what happened the present case, and the measures required by a reasonable response to the risk were simple, were readily to hand and involved no great difficulty or discernible expense: albeit that they would not entirely eliminate the risk. A system of operation which has been followed for many years without mishap, under the control of well-qualified persons, may yet be negligent. In the absence of actual experience of a risk maturing, competent persons acting (as it were) in their own environment in an operation with which they are very familiar and have often carried out with success, may be less able to perceive a risk of injury which to an outside observer is clearly foreseeable. Practice in the relevant industry or profession is relevant to negligence, and is not conclusive. Decision is for the Court. See Rosenberg v Percival (2001) 205 CLR 434 at 439 [6]-[7] Gleeson CJ and at 453-455 [62]-[63] Gummow J. See too Rogers v Whitaker (1992) 175 CLR 479 at 487. Compare Edward Wong Finance Co Ltd v Johnson Stokes & Master (a firm) [1984] AC 296 where a practice which had been virtually universal among lawyers in Hong Kong throughout living memory was held by the Privy Council to be negligent: see their Lordships' judgment delivered by Lord Brightman at 304B-308H especially 308G-H.
184 The appellants called the evidence of Ms Sandra Pearson-Adams. Ms Pearson-Adams is as well qualified to deal with safety in horse riding as a person could well be; her life has been devoted to equestrian concerns, and has included training horses and students and conducting equestrian training centres for over 30 years, Fellowship of the British Horse Society, participation in equestrian training in many ways and at high levels, production of texts and manuals, and education. In her report (Blue 21-99) she expressed clear views, in very firm terms, about the management of beginners on trail rides and said (Blue 23):
Beginner riders should only be included in an outdoor ride if they are 'on the lead rein' - this means that an experienced horse handler/rider will lead the horse/pony of the beginner so that they are always able to control the animal. The leader may be un-mounted, walking beside the rider, or mounted - if the latter case then this must only be on a suitable trained and appropriately sized/stride length animal.
185 Ms Pearson-Adams went on to say in her report that after several hours, as beginners develop some experience, skills and confidence, they may be allowed to ride off the lead for short periods. Ms Pearson-Adams reviewed and expressed opinions on what for practical purposes were all aspects of the conduct of trail riding for beginners at Otford Farm. She stated the view that a number of essential equipment items were not in use on the day of the accident. She gave grounds for an assumption that the stirrups in use were too small for Tali Ohlstein, that the helmet's coming off was more than likely due to the helmet's not having been fitted correctly, that Jared Ohlstein may not have understood the instructions, that the selection of horses and checking and adjustment of equipment were rudimentary, perfunctory and inadequate, that the horses selected proved to be inappropriate and difficult for Tali Ohlstein and Jared Ohlstein to control. She expressed adverse views on the route selected for the ride, on the disposition of the leaders among the riders, on the response after Jared Ohlstein fell off his horse; and on many matters. At many points in her report she recurred to expressions of the view that Tali and Jared because of their age and inexperience should not have participated in the trail ride without a lead rope. In the course of her supplementary report, which was directed to a report by Ms Debbie Smyth and to other material produced by the respondents, she said (Blue 95) "no reputable Equestrian Establishment will allow riders to join the trail ride until they are convinced that they can control their mounts." Her view that a child of Tali's age should not have participated in the trail ride without a lead rope is quite clear and the basis for this view in the need to know that the rider can control the mount, though less frequently reiterated, is also clear.
186 Ms Pearson-Adams' evidence in cross-examination again directed attention to the more important matter (Black 1/138):
Q. Well, your main thesis, Ms Pearson-Adams, is that nobody should be allowed out on the trail of the type that Otford Farm has unless they have had a number of horse riding lessons in a paddock; that's right, isn't it?
A. No, I didn't say that at all. I said that no-one should be allowed out without being on a leading rein and no-one should be allowed out unless they have shown they are capable of controlling the animal that they are riding. That's not a number of lessons in specific.
187 Cross-examination explored the practicality of conducting trail rides with a number of inexperienced persons.
188 Expressing views on Ms Pearson-Adams' evidence, the Trial Judge in the context of Particular (o) said (Judgment [62]-[63] Red 96-97):
62 This is an articulation of the submission that the defendants breached a duty of care to Tali in not refusing her access to going on the ride at all. This assertion is apparently significantly premised first on the opinion of Mrs Pearson-Adams, who has been an owner and operator of equestrian training centres for twenty five years in the United Kingdom and for seven years in Australia. Whilst she states that she has been a consultant to trail riding escorts, I apprehend that a recreational trail riding establishment such as Otford Farm is very different from an equestrian training centre. I note the information that she was supplied with the expert witness code of conduct. The impression I gained from her report and her evidence was that she engaged in a search for whatever she could to criticize about the Otford Farm's operation. It is not insignificant that much of her criticism is not, and cannot be, pressed in the light of the evidence which emerged. For example, her criticisms of the equipment are not sought to be supported now.
