The binding principles established by this case are: (1) Section 13 of the Companies Act 61 of 1973 confers an unfettered discretion in the strict sense, meaning appellate courts may only interfere if the court of first instance failed to exercise the discretion judicially, took irrelevant considerations into account, ignored relevant considerations, or based its decision on wrong legal principles. (2) The two-stage enquiry under section 13 requires first establishing by credible testimony that there is reason to believe the company will be unable to pay costs if unsuccessful, and only then does the court exercise its discretion whether to order security. (3) Different legal principles apply to security for costs applications against companies under section 13 compared to applications against insolvent natural persons: the latter requires proof of vexatious litigation based on inherent jurisdiction to prevent abuse of process, while section 13 provides an unfettered discretion with no requirement to show exceptional circumstances. (4) While bona fides of a company's claim is a legitimate consideration in exercising discretion under section 13, mere bona fides cannot alone justify refusing security. (5) A company seeking to avoid a security order on grounds that it would prevent pursuit of its claim must adduce evidence of inability to obtain security not only from its own resources but also from external sources such as shareholders or creditors. (6) There is a material difference between a company's inability to pay an adverse costs order and its inability to furnish security, as shareholders or creditors might be willing to provide security to enable litigation but unwilling to pay another party's costs after the company loses.
