“I remain, I confess, puzzled as to what the true position is. Is there or is there not jurisdiction in equity to award compound interest on damages (strictly compensation) in cases where the defendant owes no fiduciary duty but has acted fraudulently. One day, no doubt, it will be necessary to decide that question”
“At common law there is never interest on damages; nor would there appear to be a power in equity to award interest, simple or compound, on common law damages”
“There is no case which specifically states this in relation to damages; but the reasoning in Westdeutsche Landesbank … , which reaches the same conclusion in relation to debts, would be equally applicable in damages cases”
“Outside the trust field, equity will order interest against an agent or receiver who fails to render an account. A constructive trust found to exist because of fraud, or because of profits made from a fiduciary position (whether or not by an actual trustee), may be treated in the same way as an express trust if it is possible to identify the money and ascertain its investment history. Often however a constructive trust differs from an express trust in that there is no trust fund which preserves its identity throughout the history of investment. The existence of such a fund must then be supposed as a kind of fiction, as in the equitable remedy of tracing. In such cases compound interest will be awarded, on the analogy of the earnings that the putative trust fund ought to have made. Traditionally, in these cases as in the express trust cases, compound interest was only awarded when the fiduciary had a trade in which the money could be invested. It has been argued that since the Westdeutsche case this condition is no longer essential; but its existence is still assumed in Clef Aquitaine SARL v Laporte Materials (Barrow) Ltd. This kind of interest presents no analogy to compensatory interest on debt or damages; it depends on the proprietary character of the claim, and represents the deemed profit of the defendant rather than the deemed loss of the claimant.”
“Compound interest is only awarded in the following cases: (a) where the contract, or the usage of a trade, provides for compound interest; (b) in trust and constructive trust cases, where the claim has a proprietary flavour and the defendant has applied the money in trade, so that the award is seeking to represent the gain made by the defendant rather than the loss to the claimant; (c) in the form of special damages to cover compound interest paid by the claimant as a result of the defendant’s wrongful act or omission; (d) in arbitration cases, though the principles on which arbitrators should award compound interest have yet to emerge. ” (a) where the contract, or the usage of a trade, provides for compound interest; (b) in trust and constructive trust cases, where the claim has a proprietary flavour and the defendant has applied the money in trade, so that the award is seeking to represent the gain made by the defendant rather than the loss to the claimant; (c) in the form of special damages to cover compound interest paid by the claimant as a result of the defendant’s wrongful act or omission; (d) in arbitration cases, though the principles on which arbitrators should award compound interest have yet to emerge. ”
“Thirdly, the area of equity. The Chancery courts, again differing from the common law courts, had regularly awarded simple interest as ancillary relief in respect of equitable remedies, such as specific performance, rescission and the taking of an account. Chancery courts had further regularly awarded interest, including not only simple interest but also compound interest, when they thought that justice so demanded, that is to say in cases where money had been obtained and retained by fraud, or where it withheld or misapplied by a trustee or anyone else in a fiduciary position.”
“The position is therefore that if a plaintiff is entitled to a proprietary remedy against a defendant who has been unjustly enriched, the court may but is not bound to order the repayment of the sum with compound interest. If on the other hand the plaintiff is only entitled to a personal remedy which will be the case where, although there was initially a fiduciary relationship and the payer was entitled in equity to treat the sum received by the payee as his, the payer’s, money and trace it, but because of subsequent developments he is no longer able to trace the sum in the hands of the payee, then there is no subject matter to which the rationale on which the compound interest is awarded can be applied. The payee cannot be shown to have a fund belonging to the payer or to have used it to make profits for himself. The legal analysis which is the basis of the award of compound interest is not applicable. (It is possible that in some cases there might be an intermediate position where it could be demonstrated that the fiduciary had, over part of the period, profited from holding a fund as a fiduciary even though he no longer held the fund at the date of trial and that in such a case the court might make some order equivalent to requiring him to account for those profits; but that is not the situation which I am asked to consider in the present case.)”
“ It follows that if, as I think, Lord Brandon of Oakbrook in President of India v La Pintada Compania Navagacion S.A. [1985] A.C. 104, 116, was right to say that in the Court of Chancery the award of compound interest was limited to situations “where money had been obtained and retained by fraud, or where it had been withheld or misapplied by a trustee or anyone else in a fiduciary position,”
“Equity has adopted a broad approach to the award of interest. It has long been accepted that the equitable right to interst exists independently of statute: Wallersteiner v Moir (No.2). Equity courts have regularly awarded interest, including not only simple interest, when justice so demanded, e.g. money obtained and retained by fraud and money withheld or misapplied by a trustee or fiduciary: La Pintada.”
