For an application for upliftment of a bar and rescission of default judgment to succeed, the applicant must demonstrate: (1) the default was not wilful; (2) a reasonable explanation for the default; (3) bona fides; and (4) a good prima facie defence with reasonable prospects of success. All four requirements must be satisfied. While negligence by a legal practitioner may provide a reasonable explanation and may not constitute wilful default, this alone is insufficient if the applicant cannot demonstrate bona fides and prospects of success. A court will not grant rescission to allow the filing of pleadings that are clearly excipiable (vague, embarrassing, or disclosing no valid defence). In claims based on liquid documents such as acknowledgments of debt, the only valid defences are disputing the signature or alleging full payment of the debt. The degree of non-compliance with the rules must be assessed within the context of each case, including the litigant's overall diligence and conduct.
