The binding legal principles established are: (1) Under Rule 63 of the High Court Rules, the test for rescission of a default judgment is whether the applicant establishes 'good and sufficient cause', which comprises: (a) an acceptable explanation for the default (absence of wilful default), (b) bona fides, and (c) a prima facie defence with reasonable prospects of success. (2) 'Wilful default' connotes deliberateness with knowledge of the action and its legal consequences, and a conscious and freely taken decision to refrain from defending, but does not include a genuine mistaken belief that defence is not required. (3) Even in unopposed summary judgment applications, courts must scrutinize pleadings to satisfy themselves that judgment is warranted, particularly verifying that the cause of action is properly pleaded and the amount claimed is sufficiently liquid. (4) In lease agreements, where a lessor seeks eviction based on a contractual provision requiring cancellation of the agreement, the lessor must allege and prove both the right to cancel and actual cancellation of the lease agreement; eviction cannot be granted based solely on arrears without proper pleading and proof of cancellation.
