To establish good and sufficient cause for rescission of a default judgment under Rule 263 of the High Court Rules 1971, an applicant must demonstrate: (1) a reasonable explanation for the default; (2) bona fides in seeking rescission; and (3) prima facie prospects of success in the main matter. These factors must be weighed in conjunction with each other, and rescission will not be granted upon mere asking. In the context of land occupation in Zimbabwe, lawful authority to occupy acquired or gazetted land must be demonstrated by an offer letter, permit, or lease agreement. Unsigned, unstamped schedules or lists, even if they contain a person's name, do not constitute lawful authority. Where an applicant has no viable defence to a claim and has engaged in dilatory tactics and abuse of process, the court will exercise its discretion to refuse rescission. Legal practitioners who pursue clearly unmeritorious applications and abuse court process may be personally liable for costs de boniis propriis and may be referred to the Law Society for disciplinary action.
