When an application for dismissal for want of prosecution is made under section 236(4), the respondent bears the onus of explaining the default in prosecuting the matter. The purpose of section 236(4) is to ensure expeditious prosecution and avoid clogging the court system with dormant cases. Where a respondent provides no explanation for delays in prosecution, particularly where there is a pattern of repeated defaults, the court will not exercise its discretion in favour of the respondent. The principle of finality in litigation requires that such applications for dismissal succeed in order to bring finality to the dispute.
