" A man cannot be charged with negligence if he has no obligation " to exercise diligence." (Kemp and Dougall v. Darngavil Coal Co., Ltd., 1909 S.C. 1314 at p. 1319, quoted by Lord Thankerton in Donoghue v. Stevenson[1932] AC 562 at p. 602.) In dealing with a case of alleged negligence it is thus necessary to ascertain first what in the circumstances was the duty of the person alleged to be in fault and second to whom that duty was owed. The late John Young was riding a motor bicycle in an Edin- burgh street. What duty then was incumbent upon him? It cannot be better or more succinctly put than it was by Lord Jamieson in the Second Division in the present case when he said that " the duty of a driver is to use proper care not to cause injury " to persons on the highway or in premises adjoining the high- " way."
' To persons so placed mat they may reason- " ably be expected to be injured by the omission to take such care." The duty to take care is the duty to avoid doing or omitting to do anything the doing or omitting to do which may have as its reason- able and probable consequence injury to others and the duty is owed to those to whom injury may reasonably and probably be anticipated if the duty is not observed. [7] 2 There is no absolute standard of what is reasonable and prob- able; it must depend on circumstances and must always be a question of degree. In the present instance the late John Young was clearly negligent in a question with the occupants of the motor car with which his cycle collided. He was driving at an excessive speed in a public thoroughfare and he ought to have foreseen that he might consequently collide with any vehicle which he might meet in his course, for such an occurrence may reasonably and probably be expected to ensue from driving at a high speed in a street. But can it be said that lie ought further to have foreseen that his excessive speed, involving the possibility of collision with another vehicle, might cause injury by shock to the pursuer? The pursuer was not within his line of vision, for she was on the other side of a tramway car which was standing Between him and her when he passed and it was not until he had proceeded some dis- tance beyond her that he collided with the motor car. The pursuer did not see the accident and she expressly admits that her " terror " did not involve any element of reasonable fear of immediate " bodily injury to herself." She was hot so placed that there was any reasonable likelihood of her being affected by the deceased's careless driving. In these circumstances I am of opinion with the majority of the learned Judges of the Second Division that the late John Young was under no duty to the pursuer to foresee that his negligence in driving at an excessive speed and consequently colliding with a motor car might result in injury to the pursuer, for such a result could not reasonably and probably be anticipated. He was there- fore not guilty of negligence in a question with the pursuer. That is sufficient for the disposal of the case and absolves me from considering the question whether injury through mental shock is actionable only when, in the words of Kennedy, J., the shock arises from a reasonable fear of immediate personal injury to one- self (Dulieu v. White & Sows[1901] 2 KB 669 at p. 675) which was admittedly not the case in the present instance. It also absolves me from considering whether, if the late John Young neglected any duty which he owed to the pursuer, which, in my opinion, he did not, the injury of which she complains was too remote to entitle her to damages. I shall observe only that the view expressed by Kennedy, J., has in Scotland the support of a substantial body of authority, although it was not accepted by the Court of Appeal in England in Hambrook v. Stokes Bros. [1925] 1 K.B. 141, notwithstanding a powerful dissent by Sargant, L.J. This House has not yet been called upon to pronounce on the ques- tion either as a matter of Scots Law or as a matter of English Law, and I reserve my opinion upon it. The decision in Owens v. Liver- pool Corporation [1939] I K.B. 394, if it is the logical consequence of Hambrook's case, shows how far-reaching is the principle in- volved. On the second point it was argued that once an act is properly characterised as negligent, that is to say, as a breach of a duty of care owed to a particular person, then the party at fault is liable to that person for everything that directly follows from the negligent act whether or not it could have been foreseen as a natural and probable result of the negligent act. For this the case of In re Polemis and Furness, Withy & Co. [1921] 3 K.B. 560, was cited. Whether the law there laid down is consonant with the law of Eng- land it will be for this House to pronounce when the occasion arises. As at present advised, I doubt if it is the law of Scotland, and I could cite ample authority to the contrary. But again this is not a point which I deem it necessary to discuss now. I am accordingly for affirming the decision of the Second Divi- sion of the Court of Session and dismissing the Appeal. LordThan- kerton Lord Russell of Killowen Lord Macmillan Lord Wright Lord Porter [8] HAY or BOURHILL v. YOUNG Lord Wright MY LORDS, That damage by mental shock may give a cause of action is now well established and is not disputed in this case, but as Philli- more J. pointed out in his admirable judgment in Dulieu y. White, 1901, 1 K.B. 600, the real difficulty in questions of this kind is to decide whether there has been a wrongful act or breach of duty on the part of the Defendant vis-à-vis the Plaintiff. That being the prior question, if it is answered against the Plaintiff the matter is concluded. I shall therefore consider that issue in the first place. The Appellant, according to the finding of the Lord Ordinary, suffered substantial damage, and suffered it owing to the conduct of the motorist. But the infliction of damage on a plaintiff does not in itself give a cause of action. Damage due to the legitimate exercise of a right is not actionable, even if the actor contemplates the damage. It is damnium absque injuria. The damage must be attributable to the breach by the defendant of some duty owing to the plaintiff. Where there is no immediate physical action by the defendant upon the plaintiff, but the action operates at a dis- tance or it not direct or is what is called nervous shock, difficulties arise in ascertaining if there has been a breach of duty. Some cases are comparatively simple. Thus in Smith v. London and South Western Railway Co., L.R. 6, C.P. 14, at p. 22, Blackburn J. makes some observations, obvious enough but not to be forgotten, '
" It seems to me that if horses run away it must be quite " obviously contemplated that people are likely to be knocked " down. It must also, I think, be contemplated that persons will " attempt to stop the horses and try to prevent injury to life or " limb."
" I just got into a pack of nerves and I did not know whether I was going to get it or not."
" the shock where it operates through the "mind must be a shock which arises from a reasonable fear of " immediate personal injury to oneself."
" It may be (I do not say that it is " so) that a person venturing into the streets takes his chance of " terrors. If not fit for the streets at hours of crowded traffic he or " she should not go there," says at p. 685, "
" I " think there may be cases in which A owes a duty to B not to inflict " a mental shock on him or her and that in such a case if A does " inflict such a shock upon B, and physical damage thereby ensues, "
"... What a man ought to have antici- " pated is material when considering the extent of his duty. "
" It may well be that " the duty of a person to take care does not extend to a person in the " position of the plaintiff in Smith v. Johnson & Co. [supra) or to "the person indicated as B in Kennedy J.'s illustration, and yet "may extend to a person in the position of the plaintiff's wife."
" Apart from the admission in the " pleadings I think that the cause of action is complete. The duty " of the owner of a motor car in a highway is not a duty to refrain " from inflicting a particular kind of injury upon those who are " in the highway. If so, he would be an insurer. It is a duty to " use reasonable care to avoid injuring those using the highway. "
'In "my opinion it is not necessary to treat this cause of " action as based upon a duty to take reasonable care to avoid "administering a shock to wayfarers. The cause of action, as " I have said, appears to be created by breach of the ordinary " duty to take reasonable care to avoid inflicting personal injuries " followed by damage, even though the type of damage may be "unexpected, namely, shock. The question appears to be as to "the extent of the duty and not as to remoteness of damage." Sargant L.J. differed and like Kennedy J. would confine liability to cases of reasonable fear for personal safety but only because in his view the injury complained of could not reasonably have been anticipated and therefore the defendant had broken no duty which he owed to the defendant. At p. 162 he says: " . . . I should "prefer, with Kennedy J., to put it not on the ground that the "harm was too remote a consequence of the negligence but on " (what is often practically equivalent) a consideration of the extent "of the duty of the defendant towards the plaintiff and others " on and near the highway. That is to say that, as the defendant " did not do anything which could reasonably or naturally be " expected to cause the harm in question to the plaintiff, there was "no evidence of any breach of duty towards him for which the " defendant could be rendered liable." In the result the plaintiff succeeded. A conclusion in favour of the plaintiff was also reached by the Court of Appeal in Owens v. Liverpool Corporation [1939], I K.B. 394, in which the driver of a tram negligently ran into a hearse containing the body of a relative of the plaintiffs and was held liable to them in respect of illness caused by the shock of seeing the accident. The Lords Justices seem to have accepted the view that the driver ought to have anticipated that the result of his negligence might be to cause emotional distress to spectators of the consequent accident and therefore was guilty of negligence towards any one physically affected by feelings induced by the sight presented to them. With all respect I do not myself consider the Court of Appeal justified in thinking that the driver should have anticipated any injury to the plaintiffs as mere spectators or that he was in breach of any duty which he owed to them. I have however dealt with both these cases and particularly with Hambrook v. Stokes (supra) somewhat at length because they show the high water mark reached in claims of the character now in question. It will be observed that in the earlier case all the Lords Justices were careful to point out that the vital problem was the extent of the duty and not the remoteness of damages— a view in which they were supported by the opinions of Kennedy and Phillimore JJ. in Dulieu v. White (supra). With this view I agree, and ask myself whether the defenders in the present case owed any duty to the pursuer. In the case of a civil action there is no such thing as negligence in the abstract: there must be neglect of the use of care towards a person towards whom the defendant owes the duty of observing care. And I am content to take the statement of Lord Atkin in Donoghue v. Stevenson [1932], A.C. 562, at p. 580, as indicating the extent of the duty. '
