In applications for rescission of default judgments under Rule 27 of the High Court Rules, SI 202 of 2021, an applicant must establish 'good and sufficient cause' by providing a clear and adequate explanation for the specific default that led to the judgment sought to be rescinded. Where an applicant fails to adequately explain the default giving rise to the judgment under review (in this case, the default on 27 March 2025), and instead focuses on explaining a different, earlier default (4 March 2025), the applicant has not satisfied the requirements for rescission. The mere assertion that one was not served with a Notice of Set Down, without further elaboration or supporting evidence, is insufficient to constitute good and sufficient cause. Furthermore, where an earlier order striking out a defence remains extant and unreversed, an applicant cannot obtain relief reinstating that defence through a subsequent rescission application that does not address the earlier order.
