The City of Johannesburg and several municipally owned utilities were participating employers in the South African Local Authorities Pension Fund (SALA). In 2004 they gave notice that they would terminate their participation in SALA and, from 1 January 2005, cease employer contributions to SALA and instead contribute to the eJoburg Retirement Fund. Employees effectively became paid-up members of SALA while contributing to eJoburg. SALA, supported by trade unions and some individual members, applied to the High Court to set aside the employers’ decision as unlawful. The employers raised a preliminary objection that the affected employee-members had not been joined to the proceedings. The High Court dismissed the non-joinder objection and set aside the employers’ decision. The employers appealed to the Supreme Court of Appeal.
