A substantive application for condonation must be made before the court can exercise its discretion to condone non-compliance with time limits prescribed by the rules of court. Rule 4C(a) of the High Court Rules, which permits the court to authorize or condone a departure from the rules in the interests of justice, does not operate as an automatic alternative to a formal condonation application. Where a party is aware that an application is out of time and this is pointed out in opposing papers, the failure to file a substantive application for condonation is fatal to the main application. The making of an application for condonation is what triggers the court's discretion to extend time, and without it, the court cannot properly consider the factors relevant to granting condonation (extent of delay, explanation for delay, prospects of success, and prejudice to the other party).
