Ismail Moosa Lunat v Mohamed Zakariya Patel and The Deputy Sheriff, Bulawayo

The 1st respondent obtained summary judgment against the applicant under HB 196/19 on 12 December 2019 for payment of USD $384,177 or its equivalent at the prevailing interbank rate. A Writ of Execution was subsequently obtained. On 17 March 2020, the applicant's attorneys paid RTGS $384,177 to the 1st respondent's attorneys. The 1st respondent's attorneys rejected this payment as insufficient, insisting on payment in USD or its interbank equivalent, and proceeded with execution. The applicant filed an urgent chamber application to interdict the sale of his assets, arguing that by operation of Statutory Instrument No. 33 of 2019 and the Finance Act No. 2 of 2019, all debts denominated in USD immediately before 22 February 2019 were automatically converted to RTGS$ at a one-to-one rate. The applicant relied on the Supreme Court judgment in Zambezi Gas Company (Pvt) Ltd v NR Barber (Pvt) Ltd SC 3/20 which had clarified the law on currency conversion. A Notice of Appeal against the original judgment had been filed on 17 December 2019.

• Whether the urgent chamber application was properly brought in the correct form (Form 29)
• Whether the application met the test of urgency
• Whether the court could stay execution of its own judgment based on subsequent legislative and judicial developments
• Whether payment of RTGS $384,177 constituted full settlement of a judgment debt originally denominated in USD $384,177 by operation of SI 33/2019 and Finance Act No. 2 of 2019
• Whether the Supreme Court judgment in Zambezi Gas Company (Pvt) Ltd v NR Barber (Pvt) Ltd SC 3/20 affected the enforceability of the original judgment
• Whether the court has power to regulate its own processes and orders

1. The points in limine are hereby dismissed. 2. The matter is to be heard on the merits. 3. Costs in the cause.

A court has the inherent power to regulate its own processes and to stay execution of its own judgments where subsequent binding precedent from a superior court or legislative changes fundamentally affect the legal basis for execution. Where the Supreme Court has pronounced definitively on the legal effect of currency conversion legislation (specifically that debts denominated in USD before 22 February 2019 were converted to RTGS$ at a one-to-one rate by operation of SI 33/2019), the High Court is bound by that precedent and must apply it even to its own previously granted judgments. In the interests of justice and fairness, matters raising substantial questions about the enforceability of judgments in light of changed legal circumstances should be heard on the merits rather than dismissed on preliminary procedural grounds.

The court observed that it would be a travesty of justice to allow execution to continue when the law had been clearly set out by the Supreme Court. The court noted that it was not reviewing its own judgment in HB 196/19, but rather addressing the question of execution in light of subsequent legal developments. The judge commented that the effect of the Zambezi Gas (Pvt) case was to settle the law regarding the fate of judgment debts arising before 22 February 2019, describing this as a 'notorious fact'. The court also noted, without deciding, that a Notice of Appeal had been filed against the original judgment on 17 December 2019.

This case is significant in Zimbabwean jurisprudence as it demonstrates the High Court's recognition of the binding effect of the Supreme Court's interpretation of currency conversion legislation (SI 33/2019 and Finance Act No. 2 of 2019) on existing judgment debts. It illustrates the principle that courts have inherent power to regulate their own processes, particularly in light of subsequent legislative changes and binding Supreme Court precedent. The case arose during Zimbabwe's currency transition period and highlights the legal complications arising from the conversion from USD to RTGS$ currency. It establishes that the interests of justice may require courts to reconsider the execution of judgments when fundamental changes in applicable law occur, even after judgment has been granted. The case also demonstrates procedural flexibility in urgent applications where substantive justice issues arise from changed legal circumstances.
