An applicant seeking urgent relief must make full disclosure of all material facts that might affect the granting or otherwise of an order. Where an applicant fails to disclose material facts, whether willfully and mala fide or negligently, which might have influenced the court's decision on whether to grant the order, the court has discretion to dismiss or set aside the application. Material non-disclosure that goes to the core of urgency, such as failing to disclose alternative accommodation when claiming desperate need for accommodation, justifies dismissal of an urgent application.
