In an application for condonation for late filing of an application for leave to appeal, the test is whether it is in the interests of justice to grant condonation, considering factors including the nature of relief sought, extent and cause of delay, effect on administration of justice, reasonableness of explanation, importance of the issue, and prospects of success. An applicant must give a full and reasonable explanation covering the entire period of delay. Where the explanation for a substantial portion of the delay is unreasonable or non-existent and manifests disrespect for the judicial process, and where prospects of success are weak, condonation will be refused even in matters involving constitutional rights such as housing and eviction. The fact that delay may be partially attributable to attorneys' conduct does not excuse unreasonable delay during periods when legal representation was available and functioning. Non-compliance with time limits in court rules has serious consequences for the efficient functioning of courts, administration of justice, and access to justice, and cannot be routinely condoned.
