HMI Healthcare Corporation (Pty) Ltd (HMI) was the sole shareholder of Calabash Health Solutions (Pty) Ltd (in liquidation), which had concluded a capitation agreement with Medshield Medical Scheme. After disputes, the agreement was terminated and Calabash was placed into voluntary liquidation. Medshield proved substantial claims against Calabash, which were expunged or rejected by the Master, who directed Medshield to pursue its claims by action. While Medshield’s action against Calabash was pending, HMI brought an ex parte application under ss 387(4) and 388 of the Companies Act 61 of 1973 authorising it to defend Medshield’s action and to institute proceedings against Medshield in Calabash’s name. That order was granted in Medshield’s absence. Medshield later applied for rescission of the ex parte order under Rule 42(1)(a) of the Uniform Rules of Court, contending it was an affected party. The rescission application succeeded, and HMI unsuccessfully appealed to the full court and then to the Supreme Court of Appeal.
