Atiwoneyi Miles Masiyiwa v Felix Munetsi Gapa and Deputy Sheriff of Harare

The court a quo ordered the appellant (defendant) to pay the respondent (plaintiff) damages equivalent to the current market value of property in dispute, and to pay interest on those damages at the prescribed rate from the date of summons to the date of payment. The property was evaluated on 4 July 2005. The appellant was served with a Writ of Execution on 19 July 2005. The appellant did not challenge the substantive order requiring payment of damages based on current market value, but appealed only against the order requiring interest to be calculated from the date of summons rather than from a later date when the quantum of damages was determined.

• At what point does a debtor become in mora for purposes of calculating interest on unliquidated damages?
• Whether interest should run from the date of summons or from the date when the quantum of damages was assessed/determined
• Whether the court a quo erred in ordering interest from the date of summons when damages were based on a property valuation conducted three years later

1. The appeal was allowed with costs. 2. The judgment of the court a quo was altered to order: (a) Defendant shall pay plaintiff damages based on the current market value of the property in issue, such value to be determined by an estate agent appointed by the Registrar; (b) Defendant shall pay interest on the market value at the prescribed rate from 4 July 2005 (date of evaluation) to the date of payment in full; (c) Defendant shall pay costs of suit.

On a claim for unliquidated damages, a defendant cannot be in mora until the quantum of damages has been fixed or becomes ascertainable. Where damages are based on a property valuation conducted after summons is issued, interest runs from the date of the valuation report (when the defendant receives notice of the quantum) rather than from the date of summons. A debtor becomes liable for interest from the point when he has notice of the determined quantum of his liability, not from the date proceedings are instituted for unliquidated claims.

The Court observed that the issuance of a warrant of execution normally follows the failure by a defendant to comply with a court order and is premised on the assumption that prior notice of the court order would have been received but ignored. The Court also noted that where a lower court has clearly not applied its mind to an issue, there is no concern about an appellate court interfering with the discretion of the lower court when correcting the error.

This case clarifies the application of the common law principle of mora in the context of unliquidated damages in Zimbabwean law. It establishes that where damages are to be determined based on a future valuation, interest cannot run from the date of institution of proceedings, but only from the date when the quantum becomes ascertainable. The case demonstrates the court's willingness to correct orders where the lower court has not properly applied its mind to important legal issues such as the calculation of interest. It reinforces established principles from South African case law regarding when a debtor is in mora for unliquidated damages.
