The plaintiffs (Dipak Patel and Raymond Louw) signed identical buyback agreements on 16 June 1999 in respect of two properties owned by the defendant companies (Havelock Court (Pvt) Ltd and Kantora (Pvt) Ltd). The agreements were part of a debt restructuring arrangement whereby Patel's friend, Mahomed Jassat, who owned Young Blood Investments, required additional security for debts owed to Allen Wack & Shepard (a clearing agent). The agreements granted the plaintiffs a 10-year option to repurchase the properties at the original price ($6 million for one property and $9 million for the other) plus interest at 43.5% per annum compounded monthly from the date of signature to the date the option was exercised. Clause 3 required that if the option was exercised, the purchase price and transfer costs must be deposited within one month, failing which interest would accrue at 43.5% per annum. If full payment was not made within three months of exercising the option, the company could cancel the sale and all option rights would cease. On 17-18 June 2004, the plaintiffs exercised their options, offering a total of $30 million for both properties, calculated using the in duplum rule (limiting interest to the capital amount). The defendants rejected this calculation and provided their own figures totaling over $127 million based on the contractual formula. The plaintiffs failed to pay within three months, and on 4 October 2004, the defendants cancelled the agreements. The plaintiffs then brought this action seeking a declaration that the in duplum rule applied, or alternatively that the defendants prematurely cancelled the agreements.
