The first respondent (Industro-Clean (Pty) Ltd) held 80% of shares in the second respondent (Industro-Clean (North West) (Pty) Ltd), which had an exclusive right to market certain products in the North-West region. The first appellant was the sole director of the second respondent from January 2002 to 19 March 2003. During this period, he breached his fiduciary duties by allowing the second respondent to sell goods purchased on credit from the first respondent at cost price to the third appellant (a close corporation of which the second appellant, his wife, was sole member), so that the third appellant could profit from on-selling them in direct competition with the second respondent. This resulted in secret profits of R148,665.92 to the first appellant indirectly. The trading account balance between the respondents increased by R572,507.98 during the period 1 March 2002 to 19 March 2003. The second respondent had been technically insolvent since 1999 but continued trading because the first respondent subordinated its claim to other creditors and extended credit. The first respondent brought a claim under s 424 of the Companies Act 61 of 1973 seeking to hold the appellants personally liable for the increased debt of R572,507.98.
