Where a party files a court application and the opposing party files a notice of opposition, the applicant must comply with Rule 236(3) by filing an answering affidavit or setting the matter down for hearing within one month. Failure to do so entitles the opposing party to apply for dismissal of the application for want of prosecution. Where a party's conduct in failing to prosecute an application amounts to an abuse of process and a deliberate delay tactic, the court may express its displeasure through an award of costs on the legal practitioner-client scale.
