Publiserve Healthcare Scheme, a medical scheme under the Medical Schemes Act 131 of 1998, became insolvent and was wound up in May 2001. Prior to liquidation, Publiserve made five payments totalling R5 454 636.50 to Afrisure CC, an accredited broker and alter ego of its sole member, Mr Ettienne de Villiers, who was also a trustee of Publiserve during part of the relevant period. The payments were made pursuant to a proposal under which Afrisure introduced approximately 6 750 members to Publiserve and received broker’s commissions and ongoing monthly ‘service fees’. After liquidation, the liquidator, Mr Watson, sued Afrisure for repayment of the amounts on the basis of unjustified enrichment, alleging that the payments were illegal as they contravened the Medical Schemes Act and regulations, were in fraudem legis, and/or were made by mistake. In addition, Watson sued De Villiers personally for damages on the basis that he breached his fiduciary duties as a trustee by causing or permitting these illegal payments.
