A matter ceases to be urgent if it is founded upon deliberate misrepresentation or the holding back of vital information. Courts will dismiss urgent applications characterized by material non-disclosures, mala fides, or dishonesty, regardless of the merits. Legal practitioners, as officers of the court, have a duty to disclose all material information to the court, including prior adverse rulings by other judges on the same or similar applications. Forum shopping by withdrawing an application after an adverse preliminary ruling and immediately refiling a virtually identical application before a different judge, without disclosing the prior ruling, constitutes conduct warranting dismissal with costs. The duty to disclose material information extends to all matters brought before the court, whether on an urgent basis or not.
