Joanne Elizabeth Crogham v Gary Francis Wellock

The parties were divorced by court order on 6 December 2018 in case HC 893/14, with ancillary relief granted based on a consent paper. The order dealt with assets including aircrafts valued at $170,000 and an immovable property (9 Knight Bruce Road, Milton Park, Harare) owned through Mescal Investments (Pvt) Ltd. The applicant contended that the respondent failed to fully comply with the court order, particularly regarding maintenance of minor children. The applicant also noticed that the aircraft valuation did not expressly specify United States dollars. Given the currency redenomination in Zimbabwe (through S.I. 33 of 2019 and S.I. 142/2019), the applicant feared the respondent would take advantage of the RTGS dollar conversion at 1:1, which would be unfair as the original valuation was in USD. The applicant also sought to vary the provision regarding the house, as the children had completed secondary education and continuing joint ownership kept the parties financially tied together. Service was effected on 31 August 2021 through the Sheriff at the respondent's legal practitioners' offices. The respondent's attorneys sought a 10-day indulgence which was granted, but no opposition was filed thereafter.

• Whether the court had jurisdiction to vary its own final order (functus officio doctrine)
• Whether the matter was res judicata
• Whether the variation sought was an attempt to subvert currency legislation (S.I. 33/2019, S.I. 142/2019, and Finance (No. 2) Act, 2019)
• Whether good cause had been shown for the variation under section 9 of the Matrimonial Causes Act
• Whether proper service of the application had been effected

The court granted the application and varied the 6 December 2018 order as follows: (1) The aircraft valuation was expressly stated as US$170,000.00, with the defendant to pay plaintiff US$85,000.00 within 90 days, alternatively the aircrafts to be valued and defendant to pay plaintiff 50% of the value within 90 days; (2) The immovable property at 9 Knight Bruce Road, Milton Park, Harare to be valued by a reputable estate agent and sold within 90 days with net proceeds shared equally; (3) All other provisions of the 6 December 2018 order not specifically amended to remain in force; (4) Respondent to pay costs of suit.

Section 9 of the Matrimonial Causes Act [Chapter 5:13] provides an exception to the functus officio doctrine and res judicata principles, empowering courts to vary orders made under section 7 of the Act on good cause shown. 'Good cause' means any reason which would render it equitable for the court to exercise its discretion in favour of the applicant. Where an order is based on a consent paper expressing the parties' intentions, and circumstances have changed (such as currency redenomination or children completing education), a court may exercise its discretion to vary the order to achieve equity between the parties, provided the variation does not subvert applicable legislation but rather gives effect to the original intentions of the parties.

The court observed that the consent paper arrangement had the effect of divorcing the parties but keeping them tied together financially for four years, which the applicant described as an oversight. The court also made general observations about the functus officio doctrine, citing Minister of Justice v Ntuli 1997 (3) SA 772 (CC) and De Villiers v BOE Bank Ltd 2004 (3) SA 459 (SCA), noting that while courts generally cannot vary their own final orders, statutory provisions may empower them to do so. The court noted its initial concerns about whether the variation sought might be an attempt to subvert currency legislation (S.I. 33/2019, S.I. 142/2019, and sections 20-24 of the Finance (No. 2) Act, 2019), but these concerns were allayed in the context of an unopposed matter based on a consent paper.

This case demonstrates the application of section 9 of the Matrimonial Causes Act [Chapter 5:13] as an exception to the functus officio doctrine and res judicata principles in matrimonial matters. It confirms that courts retain jurisdiction to vary ancillary relief orders in divorce proceedings on good cause shown. The case also illustrates how courts handle currency redenomination issues in the context of existing court orders, particularly where the original intention of parties needs to be preserved despite subsequent legislative changes. It emphasizes the equitable nature of the discretion to vary matrimonial orders and shows that consent-based orders can be varied to reflect the true intentions of parties and changed circumstances (such as children completing education).
