“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. This does not, however, to my mind, mean that you exclude entirely all attributes of the plaintiff other than that he is a plaintiff. There is evidence here that large public companies of the size and prestige of these plaintiffs could expect to borrow at 1% over MLR [minimum lending rate], while for smaller and less prestigious concerns the rate might be as high as 3% over MLR. I think it would always be right to look at the rate at which plaintiffs with the general attributes of the actual plaintiff in the case (though not, of course, with any special or peculiar attribute) could borrow money as a guide to the appropriate interest rate.” (4) Thus, the parties may demonstrate that an entity with the claimant’s general attributes, following “categorisation of the plaintiff in an objective sense” (Steyn J in Banque Keyser Ullman), could at the relevant time borrow on the markets at a particular rate. Specific features of the claimant (for example in relation to personal creditworthiness) will be disregarded in order to save time and money at trial, and so there is no need to seek to measure the “actual loss” of the actual claimants (Steyn J in Banque Keyser Ullman). (5) Until recently, the presumption in the Commercial Court, often adopted in business disputes, was that the rate of interest should be 1% above base rate. However, in the present financial circumstances, where the spread between base rate and the actual cost of borrowing is much greater than in the past, that presumption has largely fallen away: and the latest Commercial Court Guide indicates that there is no longer such a presumption; and see Sycamore Bidco Ltd v Breslin[2013] EWHC 174 (Ch) per Mann J at para 51. (6) Moreover, there is also a consistent line of authority supporting rates above the Commercial Court rate where the claimant is a small business or (as in this case) a group of individuals. Thus: (a) In Jaura v Ahmed[2002] EWCA Civ 210 , the “real costs of borrowing incurred by… small businessmen” were fixed at 3% over base, Rix LJ observing (at paragraph 26) that “The law should be prepared to recognise, as I suspect evidence might well reveal, that the borrowing costs generally incurred by them are well removed from the conventional rate of 1% above base (and sometimes even less) available to first class borrowers”
“The practice whereby interest is normally awarded at 1 per cent over base rate amounts to a presumption which can be displaced if its application would be substantially unfair to either party. That rate represents something of a compromise (albeit weighted in favour of the plaintiff) between what a [plaintiff kept out of his money might have earned on it and what he might have had to pay by way of interest…”
“Ultimately, in civil proceedings, it is for the court to determine what that standard [of honest behaviour] is and to apply it to the facts of the case.”
