The applicant obtained a default judgment against the respondent on 26 February 2018 under HC 4277/15 for payment of USD$179,000 with interest and declared a property especially executable. The respondent made payment proposals which were accepted but failed to honor them. On 13 November 2019, the parties entered into a deed of settlement wherein the respondent agreed to settle an outstanding debt of USD$155,440, with two residential stands in Hatfield to be sold and proceeds paid to the applicant, and agreed to continue paying USD$5,000 per month until the debt was extinguished. After 22 February 2019, Presidential Powers (Temporary Measures) Regulations SI 33/2019 was promulgated, converting USD debts to RTGS dollars at 1:1. The respondent continued to service the debt in USD after this date. Following the Supreme Court decision in Zambezi Gas Zimbabwe v NR Barber SC 3/20, which interpreted SI 33/2019 as converting judgment debts to RTGS at 1:1, the respondent claimed the debt was extinguished and that the deed of settlement was void ab initio due to common mistake of law.
The court declared that the Deed of Settlement signed on 13 November 2019 compromised the High Court order of 26 February 2018 and created new obligations between the parties. The respondent was ordered to pay the applicant USD$145,440 (the balance due under the deed of settlement) payable at the prevailing interbank rate, plus interest at the prescribed rate from 29 February 2020 to date of full payment. Stand 171 Ardbennie Township (Number 15 Cannock Close, Houghton Park, Waterfalls, Harare) was declared specially executable. The respondent was ordered to pay costs of suit on a legal practitioner-client scale.
A compromise agreement (deed of settlement) that varies the terms of a court order creates new rights and obligations separate from the original judgment, thereby extinguishing the original cause of action which becomes res judicata. Once parties enter into a valid compromise agreement with different terms from a court order, the debt ceases to be a judgment debt and the parties' rights and obligations are governed solely by the contractual terms of the compromise agreement. Mistake of law, including misapprehension as to the applicability or interpretation of statutory provisions, does not void a contract or compromise agreement based on the principle ignorantia juris non excusat (ignorance of law is no excuse), as all persons are presumed to know the law. A compromise agreement will only be voidable on grounds of fraud, justus error, common mistake of fact, misrepresentation or other ground for rescission; a unilateral or common mistake of law does not qualify. Where parties expressly agree that a contractual obligation shall be paid in foreign currency, courts will give effect to that intention. The ratio can be summarized as: statutory provisions mandating currency conversion of judgment debts (such as SI 33/2019) do not apply where the judgment debt has been novated and extinguished by a subsequent compromise agreement that creates new contractual obligations in a specified currency.
The court observed that had the respondent not entered into payment plans and the deed of settlement with the applicant, he would have been entitled to pay the debt pursuant to the court order in RTGS dollars at 1:1 to USD in terms of section 4(1)(d) of SI 33/2019 as interpreted in the Zambezi Gas case. The court noted that the respondent "took the risk and complicated his case by making offers to pay in United States dollars and entering into the deed of settlement as it has not turned out to be advantageous to him." The court also made general observations about the nature and requirements of compromise agreements, noting that they require offer and acceptance, consideration, capacity to contract, mutual intent to settle the dispute and bring it to an end, and reciprocal concessions. The court emphasized that compromise agreements enable parties to settle disputes outside court and create rights and obligations separate from the original cause of action, with the effect that once entered into, a defendant has no entitlement to raise defenses to the original cause of action. The court further observed that parties have latitude to vary a court order by way of a deed of settlement, and once varied, the creditor may not recover the debt based on the court order as the deed becomes a compromise at law and the court order ceases to regulate the relationship between the parties.
This case is significant in Zimbabwean law for clarifying the legal effect of compromise agreements and their relationship to currency conversion regulations. It establishes that: (1) parties can validly vary a court order through a deed of settlement, which creates new contractual obligations that supersede the original judgment debt; (2) once a valid compromise agreement is concluded, it extinguishes the original cause of action and parties cannot raise defenses to the original claim; (3) mistake of law (including misunderstanding of statutory provisions like SI 33/2019) does not void a contract based on the principle that ignorance of law is no excuse; (4) parties' express intentions regarding currency of payment will be given effect even where statutory provisions might otherwise mandate conversion; (5) the Zambezi Gas principles regarding conversion of USD judgment debts to RTGS do not apply where parties have subsequently novated the judgment debt through a compromise agreement. The case also reinforces the principle that courts will uphold freedom of contract and hold parties to voluntarily assumed obligations, particularly where those obligations were undertaken with knowledge of the legal position (even if that knowledge was imperfect). This decision is particularly important in the context of Zimbabwe's complex currency transition period and provides guidance on when currency conversion regulations apply versus when contractual arrangements take precedence.
