"Liability for damage done by dangerous animals 2. -- 1. Where any damage is caused by an animal which belongs to a dangerous species, any person who is a keeper of the animal is liable for the damage, except as otherwise provided by this Act. 2. Where damage is caused by an animal which does not belong to a dangerous species, a keeper of the animal is liable for the damage, except as otherwise provided by this act if -- a. the damage is of a kind which the animal, unless restrained, was likely to cause or which, if caused by the animal, was likely to be severe; and b. the likelihood of the damage or of its being severe was due to characteristics of the animal which are not normally found in animals of the same species or are not normally so found except at particular times or in particular circumstances; and c. those characteristics were known to that keeper or were at any time known to a person who at that time had charge of the animal as that keeper's servant or, where that keeper is the head of a household, were known to another keeper of the animal who is a member of that household and under the age of sixteen."
"2. A dangerous species is a species -- a. which is not commonly domesticated in the British Islands; and b. whose fully grown animals normally have such characteristics that they are likely, unless restrained, to cause severe damage or that any damage they may cause is likely to be severe."
"24. .... It cannot be said here that in any sense Chance was an animal of vicious propensity -- quite the opposite -- but it does seem to me that in the circumstances which prevailed on the afternoon of this incident, if damage was caused by the animal it was likely to be severe. Chance was a heavy animal, some 600 lbs in the estimation of Mrs Bowlt. The horse was in close proximity to vehicular traffic on an A class road with a 60mph speed limit. If, as it did, the animal decided to move into the path of a car, the damage was likely to be severe. In short, the second part of subsection (a) of subsection (2) seems to me to be satisfied for similar reasons to those expressed by Lord Hobhouse when considering the application of the principles as he described them in the Mirvahedy case. 25. So far as subsection (b) is concerned, the relevant characteristic has already been described. Horses generally and this horse in particular, normally follow the direction of their rider but in particular times and in particular circumstances, horses generally (as did this horse) can assert an inclination to move otherwise than as directed. It is not normal for a horse to move into the path of a moving car -- no one contended it was normal for this horse -- but in particular times and in particular circumstances, Chance could assert her own will against that of her rider and, on this occasion, that placed her in close proximity to the claimant's car. The common sense of this is that she then became alarmed. I do not believe the court requires expert evidence to conclude that even a placid horse, finding itself in that situation, could become frightened. 26. Whether she did become frightened may not be central to the application of subsection (b). It does seem unrealistic, as I have already said, to be overly concerned with the horse's motivation at different stages of such a brief episode. It seems to me sufficient in terms of the Act that she had a characteristic that could and did lead her to move near to a moving car. That was a characteristic which would only arise at particular times and in particular circumstances. It arose on the relevant occasion and caused the accident. 27. Finally, subsection (c): the defendant is required to know of the relevant characteristic. She did, on her own admission. It may not have been demonstrated to her in this particular way before, but you can know of something, even if it has not actually arisen. She knew that the horse could decide upon some movement of its own. Frankly, if it had been put to her before the accident, I think she would have been bound to concede Chance could decide to move into the road. I consider she had knowledge, for the purposes of subsection (c). In my judgment, the claim under the Act is, for these reasons, made out."
"46. .... Take a large and heavy domestic animal such as a mature cow. There is a real risk that if a cow happens to stumble and fall onto someone, any damage suffered will be severe.
"But a cow's dangerousness in this regard may not fall within requirement (b). This dangerousness is due to a characteristic normally found in all cows at all times. The dangerousness results from their very size and weight. It is not due to a characteristic not normally found in cows 'except at particular times or in particular circumstances'."
"17. .... The claimant did not fail to do anything that a reasonably careful driver should have done. He seems to me to have approached the horses with caution and moved to the centre of the road giving room to animals that, at that stage, were on the verge. His speed was 15mph at most and the horses had given no sign of panic. I do not consider it was necessary for him to stop altogether ...."
