The appellants were trustees of three trusts (Paragon Asset Management Trust, Paragon Asset Management Trust (Western Cape), and Commercial Investment Trust) who invested on behalf of hundreds of individual investors in a business venture conducted by the Halgryn Family Trust. The investments were in the form of revolving loans that attracted high interest rates. Loans and interest were repaid for a while but the continuation of repayments was sustainable only with ever larger investments. The Halgryn Family Trust was ultimately sequestrated. During the six months immediately preceding sequestration, the trusts were periodically repaid with interest moneys they had lent to the Halgryn Family Trust. Repayments to Paragon or Paragon Western Cape amounted to R24,977,272 and repayments to Commercial Investment Trust amounted to R1,382,818. The trustees of the insolvent estate sought to recover these dispositions as voidable preferences under section 29(1) of the Insolvency Act 24 of 1936. The appellants challenged the constitutional validity of section 29(1), arguing that the onus it placed on defendants was unconstitutional.
