The court assumed, without deciding, that courts have an inherent discretion to stay proceedings on equitable grounds in the interests of justice, while noting this was not clearly established by authority. The court referenced Nicholas J's observations in Fisheries Development Corporation of SA Ltd v Jorgensen 1979 (3) SA 1331 (W) that courts do not act on abstract ideas of justice and equity but must act on principle, and cannot administer equity except in accordance with principles of Roman-Dutch law. The court also assumed, for purposes of the appeal, that if such a discretion existed it would be a discretion in the narrow sense with which an appeal court could only interfere on limited grounds (capriciousness, wrong principle, lack of unbiased judgment, no substantial reasons, or material misdirection).
