“As to (1), it seems to me that the Court's overall approach in the authorities cited to me is to distinguish between (a) cases relating to money lost in or in relation to the conduct of a business where the general assumption would be that money lost or detained would have to be replaced by money borrowed to maintain that business and (b) cases where any award is an accretion to the funds of the claimant, rather than replacement of monies which the claimant had previously had and put to use. In cases of type (a), the Court seeks to identify an appropriate interest rate, adopting a broad brush to establish a rate approximating to the cost that a claimant in that line of business or activity would have incurred in borrowing money to replace the money lost or detained. In cases of type (b), of which the paradigm may be personal injury cases, the Court seeks to identify an appropriate rate to represent a minimum return to put the claimant in the position he or she would have been if the money had been placed on deposit at the date of the event that gave rise to the claim.”
“Another matter which is generally ignored is the financial situation of the plaintiff; it should generally make no difference even if, for example, it could be shown that a plaintiff in a personal injury action was a person who would simply have paid the damages, if received earlier, into his current account at the bank which was permanently in credit.”
“I feel satisfied that in commercial cases the interest is intended to reflect the rate at which the plaintiff would have had to borrow money to supply the place of that which was withheld. I am also satisfied that one should not look at any special position in which the plaintiff may have been; one should disregard, for instance, the fact that a particular plaintiff, because of his personal situation, could only borrow money at a very high rate or, on the other hand, was able to borrow at specially favourable rates. The correct thing to do is to take the rate at which plaintiffs in general could borrow money.”
“... the proper question is: At what rate could the plaintiff borrow the required sum and not what return could the plaintiff have expected if he had invested it? It is immaterial, therefore, to consider, as Mr. Davies [Counsel for the defendant] suggested, whether the plaintiff could have used the money profitably in his own business or what rate of profit he could have expected to achieve by so doing.”
