Rule 43 Rescissions - A Case Study

The case of MPM v HSM, Case No. 008246/2025, illustrates the difficult relationship between procedural law and the best interests of children. The dispute concerned the rescission of a Rule 43 interim care order made during pending divorce proceedings. The order granted the father primary residence of the parties’ three minor sons, while the mother, who lived in Mpumalanga, received defined contact rights.

The mother sought to rescind the order, arguing that she had been denied a proper opportunity to oppose it because her former attorneys failed to file her opposing affidavit. As a result, she became ipso facto barred under the court rules. Her argument raised an important question: should a party suffer the consequences of her legal representatives’ negligence, especially in a child-care dispute?

Acting Judge Woodrow considered both Rule 42 of the Uniform Rules of Court and the common law. Under Rule 42, a judgment may be rescinded if it was erroneously sought or granted. The court found, however, that the order had been properly served and that no procedural defect existed when it was granted. The fact that the mother’s attorneys failed to act did not make the order legally erroneous.

The common-law application also failed because the mother could not establish “good cause.” A successful rescission application generally requires a reasonable explanation for the default, a genuine defence, and a demonstration that rescission would serve justice. The court emphasized that blaming former attorneys, without more, does not automatically justify setting aside a valid order.

The judgment also reflects the practical purpose of Rule 43 orders. These orders provide immediate stability during lengthy divorce proceedings and should not be repeatedly disturbed without substantial grounds. The children had already spent the academic year living with their father in Pretoria and attending school there. Changing their residence without an objective expert assessment could undermine their stability and best interests.

Although the application was dismissed with costs, the court prioritized the children by directing the Family Advocate to complete an urgent investigation. The parties may still seek variation under Rule 43(6) if that investigation supports a different arrangement. The case therefore demonstrates that procedural delay can have serious custody consequences, but that the children’s welfare remains the decisive consideration.
