Zimbabwe Teachers Association (Mashonaland West) v Thomas Nyamudzoza and Others

On 1 June 2020, the plaintiff issued summons for provisional sentence claiming US$155,138-75 based on an acknowledgment of debt signed by the defendants on 31 January 2020. In terms of this acknowledgment, the defendants undertook to pay the sum of US$155,138-75 or its equivalence at the prevailing interbank rate on or before 31 March 2020. The debt arose from money advanced towards the purchase of residential stands and costs of agreements of sale. The defendants had renounced various legal exceptions including non causa debiti, non numerata pecuniae, errori calculi, revision of accounts, and no value received. The matter initially came on the unopposed roll but the defendants appeared to oppose the claim. The defendants did not deny signing the acknowledgment of debt nor did they allege duress or undue influence.

• Whether the acknowledgement of debt sought to circumvent the effects of SI 33 of 2019 (Presidential Powers Regulations on RTGS Dollars) or the Supreme Court judgment in Zambezi Gas Zimbabwe (Pvt) Ltd v NR Barber (Pvt) Ltd SC 3-20 by being signed for the same amount owed but expressed in United States dollars
• Whether an acknowledgment of debt constitutes a new cause of action entitling a court to ignore how the debt arose, particularly where the original loan arose before the effective date in SI 33/19 (February 2019) but was subsequently reduced into an acknowledgement of debt expressed in US currency
• Whether provisional sentence should be granted on a valid acknowledgment of debt where no evidence of invalidity has been provided

1. Provisional sentence in the sum of US$155,138-75, or the equivalence at the prevailing interbank rate, was granted. 2. Defendants shall pay interest on the sum of US$155,138-75 at the prescribed rate (5% per annum) from 31 March 2020 to date of payment in full. 3. Defendants shall pay costs of suit on the legal practitioner and client scale.

1. It is competent to sue a debtor on an acknowledgment of debt without founding the action on the original transaction giving rise to that acknowledgment. 2. When dealing with provisional sentence founded on acknowledgment of debt, a court is not required to investigate the terms of the underlying agreement or transaction. 3. Provisional sentence will be granted where the acknowledgment of debt is clear and certain in the absence of evidence to demonstrate anything to vitiate it such as duress. 4. The caveat subscriptor rule applies to acknowledgments of debt - parties are bound by their signatures whether or not they read or understood the document. 5. Where defendants voluntarily sign an acknowledgment of debt and renounce legal exceptions (such as non causa debiti, non numerata pecuniae, errori calculi, revision of accounts, no value received), they cannot subsequently rely on those exceptions to escape liability.

The court initially identified two issues for consideration: (1) whether the acknowledgement of debt sought to circumvent SI 33 of 2019 or the Zambezi Gas judgment, and (2) whether an acknowledgment of debt constitutes a new cause of action allowing the court to ignore how the debt arose. However, the court ultimately found it unnecessary to definitively resolve these issues, particularly the question of circumventing currency regulations, given that the acknowledgment of debt was voluntarily signed with renunciation of exceptions. The court noted that an advocate in private practice had agreed to act as amicus curiae to assist with these complex issues, but no heads were received, and the court proceeded without that assistance. This suggests the court recognized the potential broader significance of these issues but found the case could be resolved on narrower grounds applying established provisional sentence principles.

This case clarifies important principles in Zimbabwean civil procedure regarding provisional sentence applications based on acknowledgments of debt. It confirms that courts need not investigate the underlying transaction when a valid acknowledgment of debt exists, and that such acknowledgments constitute independent causes of action. The judgment also addresses the interplay between acknowledgments of debt and currency regulations (SI 33 of 2019), holding that the form of the acknowledgment (voluntary signature with renunciation of exceptions) takes precedence over questions about whether it circumvents currency regulations. The case reinforces the caveat subscriptor principle and the limited grounds for defending against provisional sentence claims based on liquid documents.
