For a chamber application to be properly regarded as urgent: (1) it must be a matter that cannot wait to be resolved through normal application or action procedures; (2) the applicant must demonstrate that if not heard urgently, they will suffer substantial injustice or irreparable harm; (3) the court must exercise its discretion by considering cumulatively: the cause of action, nature of relief sought, probable delays with normal procedures, consequences of refusal, and other good reasons; (4) self-created urgency through inordinate and unexplained delay does not warrant urgent treatment; (5) applicants must act promptly upon becoming aware of circumstances requiring urgent relief; and (6) failure to explain delay in the certificate of urgency and founding affidavit is fatal to an urgent application.
