“14. A duty of care such as the valuer owes does not however exist in the abstract. A plaintiff who sues for breach of a duty imposed by the law (whether in contract or tort or under statute) must do more than prove that the defendant has failed to comply. He must show that the duty was owed to him and that it was a duty in respect of the kind of loss which he has suffered. Both of these requirements are illustrated by Caparo Industries Plc. v. Dickman http://www.bailii.org/uk/cases/UKHL/1990/2.html[1990] 2 A.C. 605. The auditors’ failure to use reasonable care in auditing the company’s statutory accounts was a breach of their duty of care. But they were not liable to an outside take-over bidder because the duty was not owed to him. Nor were they liable to shareholders who had bought more shares in reliance on the accounts because, although they were owed a duty of care, it was in their capacity as members of the company and not in the capacity (which they shared with everyone else) of potential buyers of its shares. Accordingly, the duty which they were owed was not in respect of loss which they might suffer by buying its shares. As Lord Bridge of Harwich said, at p. 627: "It is never sufficient to ask simply whether A owes B a duty of care. It is always necessary to determine the scope of the duty by reference to the kind of damage from which A must take care to save B harmless." In the present case, there is no dispute that the duty was owed to the lenders. The real question in this case is the kind of loss in respect of which the duty was owed. 18. Rules which make the wrongdoer liable for all the consequences of his wrongful conduct are exceptional and need to be justified by some special policy. Normally the law limits liability to those consequences which are attributable to that which made the act wrongful. In the case of liability in negligence for providing inaccurate information, this would mean liability for the consequences of the information being inaccurate. 19. I can illustrate the difference between the ordinary principle and that adopted by the Court of Appeal by an example. A mountaineer about to undertake a difficult climb is concerned about the fitness of his knee. He goes to a doctor who negligently makes a superficial examination and pronounces the knee fit. The climber goes on the expedition, which he would not have undertaken if the doctor had told him the true state of his knee. He suffers an injury which is an entirely foreseeable consequence of mountaineering but has nothing to do with his knee. 22. Your Lordships might, I would suggest, think that there was something wrong with a principle which, in the example which I have given, produced the result that the doctor was liable. What is the reason for this feeling? I think that the Court of Appeal’s principle offends common sense because it makes the doctor responsible for consequences which, though in general terms foreseeable, do not appear to have a sufficient causal connection with the subject matter of the duty. The doctor was asked for information on only one of the considerations which might affect the safety of the mountaineer on the expedition. There seems no reason of policy which requires that the negligence of the doctor should require the transfer to him of all the foreseeable risks of the expedition. 23. I think that one can to some extent generalise the principle upon which this response depends. It is that a person under a duty to take reasonable care to provide information on which someone else will decide upon a course of action is, if negligent, not generally regarded as responsible for all the consequences of that course of action. He is responsible only for the consequences of the information being wrong. A duty of care which imposes upon the informant responsibility for losses which would have occurred even if the information which he gave had been correct is not in my view fair and reasonable as between the parties. It is therefore inappropriate either as an implied term of a contract or as a tortious duty arising from the relationship between them.”
“...the question whether damage is sufficiently direct consequence of negligence to be recoverable, or is too remote, is rather a question of first impression. I am clear that if a negligent driver on the road injures himself in a collision with another vehicle, whose driver and a stranger thereupon take the injured man to hospital and meet with an accident in so doing, neither of them can recover damages for the accident from the negligent driver as consequences of his original negligence.”
“35. The first question is whether the Court of Appeal was wrong to limit the period for which damages were recoverable by reference to what was within the reasonable contemplation of the Bank at the time of the breach. Potter LJ said in para 31 that, whatever the judge's view was of the percentage chance that Samson would in fact in the following years have been Economy Bag's supplier of dog chews, the Bank's reasonable contemplation at the date of the breach introduced a cut-off point beyond which the Bank was not liable. He said that this was the effect of the rule as to remoteness in Hadley v Baxendale 9 Exch 341. 36. In my opinion there are two errors in this approach to the assessment of damages. This first may appear to be the somewhat technical point, that it is the date of the making of the contract, not the date of the breach, that was identified as the relevant date in Hadley v Baxendale. I say that it may appear to be somewhat technical because in this case the date of the making of the contract and the date of the breach were only about two months apart. There is no evidence that the facts that were relevant to what the Bank had in reasonable contemplation changed to any significant extent between22 January 1993 when the letter of credit was issued and15 March 1993 when the Bank sent Pet Products' invoice to Economy Bag. But the error was an error of principle. The choice of dates is more important than the differences, if any, in those facts. The parties have the opportunity to limit their liability in damages when they are making their contract. They have the opportunity at that stage to draw attention to any special circumstances outside the ordinary course of things which they ought to have in contemplation when entering into the contract. If no cut-off point is provided by the contract, there is no arbitrary limit that can be set to the amount of the damages once the test of remoteness according to one or other of the rules in Hadley v Baxendale has been satisfied. 37. The second error flows from the first. The Bank did not include any provision in the letter of credit limiting its liability for the loss of repeat business to any particular period. So the only limit on the period of its liability is that which the trial judge identified. This is when, on the facts, the question whether any loss has been sustained has become too speculative to permit the making of any award. He held that as time passed it was increasing likely that Economy Bag would have acquired the motive and the means to squeeze Samson's profit margins and would ultimately have ended their business relationship. Miss Andrews did not challenge this approach, although she contended that the judge should have extended his award over a longer period. It seems to me that it is amply supported by the facts of the case. Samson were in a precarious position. Mr Taylor knew who the suppliers were and he had met Mr Veerachai. He knew where he could be contacted. It was only a matter of time before the harsh reality of doing business persuaded him that he should take a closer interest in what his arrangements with Samson were costing him and ask himself whether those costs could be cut down and perhaps eliminated.”
“In these circumstances, where the Plaintiffs' loss depends upon the actions of an independent third party, it is necessary to consider as a matter of law what it is necessary to establish as a matter of causation, and where causation ends and quantification of damage begins. 1. What has to be proved to establish a causal link between the negligence of the Defendants and the loss sustained by the Plaintiffs depends in the first instance on whether the negligence consists on some positive act or misfeasance, or an omission or non feasance. In the former case, the question of causation is one of historical fact. The Court has to determine on the balance of probability whether the defendant's act, for example the careless driving, caused the plaintiff's loss consisting of his broken leg. Once established on balance of probability, that fact is taken as true and the plaintiff recovers his damage in full. There is no discount because the judge considers that the balance is only just tipped in favour of the plaintiff; and the plaintiff gets nothing if he fails to establish that it is more likely than not that the accident resulted in the injury. Questions of quantification of the plaintiff's loss, however, may depend upon future uncertain events. For example, whether and to what extent he will suffer osteoarthritis, whether he will continue to earn at the same rate until retirement, whether, but for the accident, he might have been promoted. It is trite law that these questions are not decided on a balance of probability, but rather on the court's assessment, often expressed in percentage terms, of the risk eventuating or the prospect of promotion, which it should be noted depends in part at least on the hypothetical acts of a third party, namely the plaintiff's employer. 2. If the defendant's negligence consists of an omission, for example to provide proper equipment, given proper instructions or advice, causation depends, not upon a question of historical fact, but on the answer to the hypothetical question, what would the plaintiff have done if the equipment had been provided or the instruction or advice given. This can only be a matter of inference to be determined from all the circumstances. The plaintiff's own evidence that he would have acted to obtain the benefit or avoid the risk, while important, may not be believed by the judge, especially if there is compelling evidence that he would not. In the ordinary way, where the action required of the plaintiff is clearly for his benefit, the court has little difficulty in concluding that he would have taken it. But in many cases the risk is not obvious and the precaution may be tedious or uncomfortable, for example the need to use eardefenders in noisy surroundings or breathing apparatus in dusty ones. It is unfortunately not unknown for workmen persistently not to wear them even if they are available and known to be so… Although the question is a hypothetical one, it is well established that the plaintiff must prove on balance of probability that he would have taken action to obtain the benefit or avoid the risk. But again, if he does establish that, there is no discount because the balance is only just tipped in his favour… 3. In many cases the plaintiff's loss depends on the hypothetical action of a third party, either in addition to action by the plaintiff, as in this case, or independently of it. In such a case does the plaintiff have to prove on balance of probability, as Mr Jackson submits, that the third party would have acted so as to confer the benefit or avoid the risk to the plaintiff, or can the plaintiff succeed provided he shows that he had a substantial chance rather than a speculative one, the evaluation of the substantial chance being a question of quantification of damages? Although there is not a great deal of authority, and none in the Court of Appeal, relating to solicitors failing to give advice which is directly in point, I have no doubt that Mr Jackson's submission is wrong and the second alternative is correct…”
“In that case the Court was not concerned to distinguish between causation and quantification of loss. But, in my judgment, the plaintiff must prove as a matter of causation that he has a real or substantial chance as opposed to a speculative one. If he succeeds in doing so, the evaluation of the chance is part of the assessment of the quantum of damage, the range lying somewhere between something that just qualifies as real or substantial on the one hand and near certainty on the other. I do not think that it is helpful to seek to lay down in percentage terms what the lower and upper ends of the bracket should be.”
