The binding legal principles established are: (1) An appeal against a trial court's exercise of discretion in a security for costs application will only succeed if the appellant demonstrates that the discretion was not judicially exercised or was based on wrong principles of law or wrong facts - mere disagreement with the conclusion is insufficient; (2) In applications under section 13 of the Companies Act 61 of 1973, once the applicant establishes reason to believe the respondent company cannot satisfy an adverse costs order, the court must perform a balancing exercise weighing the potential injustice to both parties; (3) The right of access to court under section 34 of the Constitution is a relevant consideration in the balancing exercise, but does not preclude the grant of security where appropriate, particularly where the plaintiff is receiving financial assistance from third parties who would benefit from a successful claim; (4) A defendant's insurance coverage is generally not a relevant consideration in determining whether to order security for costs, as it is res inter alios acta - to allow a plaintiff to benefit from a defendant's prudent insurance decision would be contrary to insurance principles and the doctrine of subrogation; (5) Where a plaintiff company is being funded by shareholders, affiliates, or third parties who would benefit from a successful claim, the court is entitled to infer that such parties could provide security, particularly in the absence of evidence establishing their inability to do so; (6) Delay in bringing a security application will not necessarily be fatal if the delay was caused or contributed to by misleading conduct by the plaintiff or its legal representatives.
