“(1) Interest is awarded to compensate claimants for being kept out of money which ought to have been paid to them rather than as compensation for damage done or to deprive defendants of profit they may have made from the use of the money. (2) This is a question to be approached broadly. The court will consider the position of persons with the claimants’ general attributes but will not have regard to claimants’ particular attributes or any special position in which they may have been. (3) In relation to commercial claimants the general presumption will be that they would have borrowed less and so the court will have regard to the rate at which persons with the general attributes of the claimant could have borrowed. This is likely to be a percentage over base rate and may be higher for small businesses than for first class borrowers. (4) In relation to personal injury claimants the general presumption will be that the appropriate rate of interest is the investment rate. (5) Many claimants will not fall clearly into a category of those who would have borrowed or those who would have put money on deposit and a fair rate for them may often fall somewhere between those two rates.”
“[w]here a claimant has delayed unreasonably in commencing or prosecuting proceedings, the court may exercise its discretion either to disallow interest for a period or to reduce the rate of interest.”
“In this context, and as is reflected in the passage quoted above, delay is not to be characterised as unreasonable unless it can be seen that the claimant has neglected or declined to pursue his claim for a significant period. The delay must truly be exceptional and inexcusable, having made allowance for the fact that delays and lulls do occur in litigation; an example would be where an action has inexcusably been allowed to go to sleep for years: see per Colman J in Athenian Harmony (No 2)[1998] 2 Lloyd’s Rep 425 at 427, in a passage also quoted in Claymore (at paragraph 52).”
“Where the matter is in doubt, the approach generally taken by the courts is (i) to assess damages on the basis of a particular hypothesis and then (ii) to scale down the award according to the probability that the hypothesis is correct.”
“The calculation of the loss”), Ward LJ, having evaluated the claimant’s chance of selling his property at£375,000 (by a certain date and producing net proceeds of£360,000 ) at 60%, then proceeded to determine the measure of damages. He began with the observation that, although he had lost that chance (valued at£216,000 ) he did not lose his property. The claimant in fact sold the property some years after the relevant date, receiving the total sum of£150,000 in two instalments some 5 and 6 years later. His lordship had first assumed that£150,000 would be credited against the£216,000 to produce a net loss of£66,000 . However, in the light of further submissions he questioned whether that was the right approach. On a point which he confessed he had not found easy to decide, he identified the issue of the quantification of damages both in a formula and in words, saying: “On the figures, is it£216,000 -£150,000 i.e.£66,000 or is it 60% of the difference between£360,000 and£150,000 i.e.£126,000 ?”
“The unfairness of the former solution can be tested in this way. Assume we had found an 80% chance of a sale. 80% of£375,000 is£300,000 . Assume the property was sold 12 months later for£300,000 . It cannot be right that the loss of such a high chance does not sound in damages. If the 0.6a – 0.6b formula is adopted, then the loss of the chance always has a value.”
“The law operates a binary system in which the only values are zero and one. The fact either happened or it did not. If the tribunal is left in doubt, the doubt is resolved by a rule that one party or the other carries the burden of proof. If the party who bears the burden of proof fails to discharge it, a value of zero is returned and the fact is treated as not having happened. If he does discharge it, a value of one is returned and the fact is treated as having happened.”
“….. if there was a 50 per cent. chance of earning£10,000 in the Army, there was equally a 50 per cent. chance that she would not earn£5,000 in civilian employment, and to arrive a true figure of actual loss the latter must be put into the equation as well as the former. Mr Pannick’s equation ignores the real, existing loss in a comparison between the£5,000 actually earned, and the£10,000 which the applicant had a 50 per cent. chance of earning. It is impossible, in my judgment, to say that an applicant who is earning£5,000 per annum following her dismissal has suffered no loss when she had a 50 per cent. chance of earning twice that amount,£10,000 .”
“The essential question is whether there is a sufficiently close link between the two and not whether they are similar in nature. The relevant link is causation. The benefit to be brought into account must have been caused either by the breach of the charterparty or by a successful act of mitigation.”
“…….. The New Flamenco is clear authority that “but for” causation is insufficient and that, before credit is given for a benefit, it must be shown to have been legally caused by the breach. This was acknowledged by Lord Sumption JSC in Tiuta[2017] 1 WLR 4627 , para 12 where he said that the general rule is that “where the claimant has received some benefit attributable to the events which caused his loss, it must be taken into account in assessing damages”
“(5) Is there a sufficient nexus between a particular element of the harm for which the claimant seeks damages and the subject matter of the defendant’s duty of care as analysed at stage 2 [i,e. the ‘scope of duty question’] above?”
