Josephine T Mukute v Innocent T Maringa

The applicant instituted summons action against the respondent seeking payment of US$51,013.00 together with interest at 5% per annum from 31 July 2011, based on an acknowledgment of debt signed by the respondent on 28 July 2011. The respondent entered appearance to defend and filed a plea admitting signing the acknowledgment of debt but disputing liability, claiming he had paid US$10,000.00. He alleged the interest charged was usurious as the applicant was not a registered money lender and could only recover interest at the prescribed rate of 5% per annum. The respondent admitted receiving a capital sum of US$33,000.00. The applicant then launched an application for summary judgment on 15 November 2011, arguing the respondent had no bona fide defence. The respondent's legal practitioners were served with the applicant's heads of argument on 29 February 2012 but failed to file heads of argument within the prescribed time, resulting in the respondent being barred.

• Whether the respondent had a bona fide defence to warrant defending the action based on an acknowledgment of debt
• Whether the interest charged by the applicant was unlawful or usurious
• Whether the prescribed rate of interest under the Prescribed Rate of Interest Act applied to contractually agreed interest rates
• Whether the respondent's failure to file heads of argument within the prescribed time warranted barring the respondent from being heard
• Whether a postponement should be granted to allow the respondent to apply for upliftment of the bar

Summary judgment with costs was granted. The respondent was ordered to pay the applicant the sum of US$51,013.93 together with interest on that sum at the rate of 5% per annum from 31 July 2012 to date of payment in full.

Where parties have agreed on a rate of interest applicable to a debt as contained in an acknowledgment of debt, the prescribed rate of interest under Section 4 of the Prescribed Rate of Interest Act does not apply. A party who is barred by reason of failure to file heads of argument within the prescribed time does not have a right of audience. An acknowledgment of debt signed without duress provides a strong basis for summary judgment unless the defendant establishes a bona fide defence, which requires more than bare allegations of unlawfulness without proper substantiation.

The court observed that where a postponement is sought to enable a party to prepare and file an application to remove a bar which has subsisted for eight months, such an application cannot be said to have any merits at all. The court also noted that the respondent failed to develop his argument relating to usurious interest and did not attempt to show why the interest was usurious, particularly given that the Usury Act had been repealed long ago. The court remarked that the interest being claimed was less than the capital debt admitted by the respondent.

This case is significant in Zimbabwean jurisprudence (note: this is a Zimbabwean case, not South African) as it clarifies the application of the Prescribed Rate of Interest Act, confirming that the prescribed rate does not apply where parties have contractually agreed to a specific interest rate. It also demonstrates the strict application of procedural rules regarding the filing of heads of argument and the consequences of being barred, including loss of right of audience. The case reinforces that acknowledgments of debt create strong prima facie cases for summary judgment where no bona fide defence is raised.
