A legal practitioner may properly depose to a founding affidavit on behalf of a client where the facts are within the practitioner's knowledge, particularly where the omission giving rise to the application was on the practitioner's part, as supported by Rule 227(4)(a). Allegations of conflict of interest require evidentiary support demonstrating actual conflict in the specific matter. In condonation applications, courts must collectively consider the factors outlined in Bessie Maheya v Independent African Church SC 58/07 (degree of non-compliance, explanation, importance of the case, prospects of success, interest in finality, court convenience, and avoidance of delay). While courts enforce strict compliance with procedural rules, they will not readily lock out a party from being heard where the deadline was missed with a reasonable explanation, particularly where justice demands that both parties be heard in important matters.
