The Municipal Employees Pension Fund (MEPF), a national pension fund for local government employees, recruited members employed by the Imbabazane Local Municipality in KwaZulu-Natal, which had historically been associated with provincial pension funds established under KwaZulu-Natal legislation (the KZN Funds). Twenty-five municipal employees joined MEPF and contributions were paid accordingly. The Municipality later concluded that, under provincial legislation and regulations, it and its employees were obliged to associate only with the KZN Funds, terminated the employees’ membership of MEPF, and stopped contributions. Litigation followed: the High Court initially ordered continued payment to MEPF, but on rescission application by the KZN Funds, held that municipalities and employees were compelled to associate exclusively with the KZN Funds. The Supreme Court of Appeal held that municipalities must associate with the KZN Funds but may also associate with other funds in addition. MEPF sought leave to appeal to the Constitutional Court, raising constitutional and statutory interpretation challenges.
