The court found that the dismissal of the succession cause was not on the merits but for want of prosecution, and that the applicants had explained their efforts to trace the file and the circumstances leading to the delay. The Law of Succession Act grants the court broad discretion to set aside its own orders, including dismissals for want of prosecution, in the interests of justice. The court exercised this discretion to set aside the dismissal, but imposed a strict condition that the applicants must obtain letters of administration by a specified date, failing which the dismissal would automatically revive. The court also ordered each party to bear their own costs.
