HOW TO ARRIVE AT RATE OF INTEREST IN COMMERCIAL CASES
In TATE and LYLE FOOD AND DISTRIBUTION LTD. V. GREATER LONDON CONOI AND ANOTHER. 1981 3 All E.R. 716 Forbes J on how to arrive at the rate of interest in Commercial cases held that one must not look at the profit which the Defendant wrongfully made out of the money he withheld but at the cost to the plaintiff of being deprived of the money which he should have had. In my view interest in commercial cases of this nature is not awarded against the Defendant as a punitive measure for having kept the plaintiff out of his money but as an attempt to achieve restitution in intergrum.
