“….the court should, as I see it, assess the likely level of damages which the claimant would have recovered had the action proceeded to judgment, and then apply an appropriate fraction to that sum to reflect the uncertainties.”
“In my judgment, the proper approach to the court to an issue of law which would have arisen in the action, which the claimant has been deprived of the opportunity to bring, is the same as in relation to an issue of fact or opinion which the claimant would have established in the action. However, at least in general, the court should in my judgment be far more ready to determine that the claimant would have failed or succeeded on a point of law than to determine that the claimant would have failed or succeeded on a point of fact or, even, opinion. That conclusion appears to me fair and practical, as well as consistent with the approach of the Court of Appeal in the three cases to which I have referred (albeit that they are not, as I have mentioned, determinative of this issue). ……. However, it is, I think, arguably implicit in the third and fourth numbered principles in the judgment of Simon Brown LJ in Mount that, at least in an appropriate case, it is right to assess damages on the “loss of a chance” basis even where the issue in the action would be one of law. At the end of his third numbered paragraph, Simon Brown LJ said that the assessment of the claimant’s claim may not be more difficult than in the action itself “where the original claim … turned on questions of law or the interpretation of documents”; his fourth numbered paragraph (quoted above) seems to apply to all types of cases encompassed within the previous paragraph. However, it would be wrong for me to place much weight on that, because, as I have mentioned, it does not seem to me that the Court of Appeal in Mount had to consider the aspect which I am now discussing.”
“Although on a strike out the judge may not have to investigate whether or not an issue or issues can still be fairly tried in great detail I think his conclusion that no such trial is possible must be the starting point for the judge who later has to make an assessment of the claimant’s prospects of success. He cannot and therefore should not attempt to try the issue or issues himself, particularly on the evidence of the negligent solicitor’s former clients’ opponent in the original proceedings. In a case like the present where the legal burden is on the claimant to show that he would have succeeded on the issue or issues in question, I do not go so far as to say that they must be assumed against the solicitor, but the application of the second and third principles in Mount’s case may in practice produce this result. So, in such a case one would normally expect the claimant to be able to show that he had real and substantial prospects of success. This will not produce unjust results; what would be unjust is for the judge to try an issue which has already been held to be untriable because of the solicitor’s negligent delay. The judge then has to evaluate those prospects applying the fourth principle in Mount’s case. This is a difficult task but no more difficult than many others involved in the assessment of damages where the court has to predict the unknown. Here, the judge is having to put a value on the claim. This is not a science, but is a task which lawyers are used to performing. The judge will obviously need to consider all the relevant material which was available up to the time when the original claim was struck out, including documents disclosed and witness statements exchanged by the other side. If he is asked to hear the evidence which the other side would have called, or expert evidence of the kind called in this case, he may agree to do so but I do not think he should feel bound to do so if he thinks he can otherwise make a fair evaluation. If he does hear such evidence, it would simply be for the purpose of enabling him to form a better broad view of the merits of the claim.”
‘39. With regard to the first stage the evidential burden rests on the negligent solicitors: they, after all, in the great majority of these cases will have been charging the claimant for their services and failing to advise him that in reality his claim is worthless so that he would be better off simply discontinuing it. The claimant, therefore, should be given the benefit of any doubts as to whether or not his original claim was doomed to inevitable failure. With regard to the second stage, the Armory v Delamirie (1722) 1 Stra 505, [1558-1774] All E.R. 121 principle comes into play in the sense that the court will tend to assess the claimant’s prospects generously given that it was the defendant’s negligence which has lost him the chance of succeeding in full or fuller measure.’ 40. The particular question raised by this appeal concerns the extent to which it is appropriate for the court hearing the loss of opportunity claim (a) to entertain primary factual evidence and (b) to reach clear conclusions whether of fact or of law. The question arises here in the context of the original claim having been struck out in April 1992 for want of prosecution on the ground that the witnesses’ memories had faded and ‘it would be impossible to investigate such matters [as the availability of alternative insurance cover] now. 41. The judge below seems to have tried this claim for all the world as if he were seised of the original action against the insurance brokers. Not only did he hear live evidence from the brokers - called, somewhat unattractively, by the defendant solicitors – but he treated the lack of oral evidence from the claimants in precisely the same way as if he had been deciding the original action.’
