Once a court issues an order prescribing timelines for filing of papers, compliance with those timelines is governed by the terms of the order itself, not merely by the general rules of court. A party seeking condonation for failure to comply with a court-ordered deadline must place cogent and satisfactory reasons before the court explaining the non-compliance. A bare request for condonation, unsupported by any explanation, provides no basis upon which a court can exercise its discretion to excuse the failure or extend further indulgence. In the absence of any explanation for non-compliance with a court order, the defaulting party may be declared in default and the matter deemed unopposed.
