The appellant, the Municipal Employees Pension Fund (MEPF), a pension fund established under Transvaal provincial legislation, sought to admit KwaZulu-Natal local authorities as participating employers and to provide pension benefits to their employees. In 2011, MEPF presented itself to the Imbabazane Local Municipality in KwaZulu-Natal as entitled to solicit membership. Twenty-five municipal employees joined MEPF and the municipality paid contributions to it. The municipality later concluded that this association was unlawful under KwaZulu-Natal pension legislation and terminated the arrangement. Although MEPF initially obtained a High Court order compelling payment of contributions, that order was later rescinded by consent. The KwaZulu-Natal based municipal pension and provident funds (the respondents), established by provincial legislation, then sought interdictory and declaratory relief preventing MEPF from operating in KwaZulu-Natal to the exclusion of the respondent funds. The High Court held that KwaZulu-Natal local authorities were obliged by legislation and regulations to associate only with the respondent funds. MEPF appealed to the Supreme Court of Appeal.
