The first respondent, Industro-Clean (Pty) Ltd, supplied goods on credit to its subsidiary, Industro-Clean (North West) (Pty) Ltd, in which it held 80% of the shares. The first appellant was the sole director of the subsidiary during the relevant period. While the subsidiary traded on a running credit account and was technically insolvent, the first appellant breached his fiduciary duties by diverting business to a close corporation controlled by his wife, thereby indirectly earning secret profits. The respondents sued the appellants, inter alia under s 424 of the Companies Act 61 of 1973, seeking a declaration that they be personally liable for the increase in the subsidiary’s indebtedness during the period of alleged reckless and fraudulent conduct. The High Court granted such an order. The appellants appealed against the order made under s 424.
