Michael Johnson v Philip Ellse and Kapp Jack Trading (Pvt) Ltd

The plaintiff, Michael Johnson, lent money to the first defendant, Philip Ellse, pursuant to two promissory notes both dated 1 December 2010. Each promissory note was for US$40,000, totaling US$80,000. The promissory notes clearly identified Philip Ellse as the "Borrower" and required repayment by 31 January 2011 (later extended to end of August 2011), with interest at a fixed monthly flat rate of 7% on the unpaid balance, payable monthly at US$2,800 per installment. Both promissory notes were signed by the first defendant in his personal capacity and witnessed by Tony Havecroft. The plaintiff paid the loan amounts to the defendant's personal account. The defendant failed to repay the principal amount. At trial, the first defendant admitted signing the promissory notes but claimed he was not the principal borrower, alleging he signed on behalf of a third party, Sam Moyo, or the second defendant company, Kapp Jack Trading (Pvt) Ltd. The plaintiff maintained that the defendant approached him for a personal loan and was the principal borrower.

• Whether the first defendant was the principal debtor/borrower under the two promissory notes
• Whether parol evidence could be admitted to contradict or vary the written terms of the promissory notes
• Whether the first defendant could escape liability by claiming he signed on behalf of a third party despite signing as the borrower in his personal capacity
• What the appropriate remedy and costs order should be

1. The plaintiff's claim against the first defendant for the sum of US$80,000.00 was upheld. 2. The first defendant was ordered to pay costs of suit on a legal practitioner and client scale. 3. The first defendant was ordered to pay interest at the rate of 7% per month from the date of issue of summons to the date of payment in full.

The binding legal principles established are: (1) Under the caveat subscriptor principle, a person who signs a promissory note identifying themselves as the "borrower" is bound by that signature and cannot escape liability by claiming they signed on behalf of an undisclosed third party without evidence of correction or amendment. (2) The parol evidence rule prevents parties from contradicting, altering, adding to or varying the contents of a written document by oral evidence where the document has been reduced to writing and is regarded as the exclusive memorial of the transaction. (3) A promissory note under the Bills of Exchange Act constitutes an unconditional undertaking to pay, and breach of such an undertaking attracts legal consequences. (4) Courts will not create a new contract for parties who have freely and voluntarily entered into a written agreement - the contract becomes sacrosanct when enforcing it. (5) The in duplum rule operates to limit interest claims to double the principal amount.

The court made observations about the defendant's conduct being "silly" (using the defendant's own characterization) in signing promissory notes without seeking legal advice if he believed he was not the principal borrower. The court also commented that the defendant's conduct in attempting to escape liability was a deliberate attempt to waste the court's time and that of the plaintiff, which justified a punitive costs order. The court cited with approval the judgment of Mushore J in First Mutual Investment (Private) Limited v Jonsput Trading (Private) Limited And Others HH1/2016 regarding the sanctity of contracts and the court's inability to create new contracts for parties.

This case reinforces fundamental principles of Zimbabwean contract law, particularly: (1) the caveat subscriptor principle that parties are bound by documents they sign; (2) the parol evidence rule that written agreements cannot be contradicted by oral evidence; (3) the sanctity of contracts freely entered into; and (4) the application of the Bills of Exchange Act to promissory notes as unconditional undertakings to pay. The case also demonstrates the court's willingness to impose punitive costs orders (on a legal practitioner and client scale) where a party attempts to deliberately escape clear contractual obligations and wastes court time. It serves as a warning against attempting to resile from clear written obligations through unsubstantiated claims of agency or third-party arrangements.
