BOE Bank Ltd (formerly NBS Bank Ltd) concluded a written loan agreement in 1991 with The Grange Timber Farming Co (Pty) Ltd to finance a long-term timber farming operation forming part of a tax-driven investment scheme controlled by Mr Robin Patrick Thorpe. The loan was supported by suretyships from related companies and Thorpe personally. The agreement provided for a final repayment date of 28 February 2007, but also included a review clause (clause 6.3) entitling the bank, by written notice before 1 September 1998, to require repayment of the entire indebtedness as at the review date (29 February 1999) and to cease funding thereafter. In August 1998, the bank invoked this clause and demanded repayment of R6.2 million as at the review date. The defendants resisted payment, contending that clause 6.3 did not accelerate repayment and that the claim was premature. The magistrate’s court and Natal Provincial Division upheld the defendants’ interpretation, leading to the bank’s appeal to the Supreme Court of Appeal.
