The South African Local Government Bargaining Council (SALGBC), together with SALGA and the majority trade unions IMATU and SAMWU, concluded a collective agreement in September 2021 titled the Retirement Fund Collective Agreement. The agreement introduced an accreditation regime requiring all retirement funds operating in the local government sector to meet prescribed criteria, including permitting transfers of members between accredited funds and amendments to fund rules. Several existing municipal retirement funds and related entities challenged the legality of the agreement in the Gauteng High Court, arguing that it impermissibly regulated pension fund governance, coerced trustees to amend fund rules contrary to the Pension Funds Act, and addressed matters not constituting terms and conditions of employment or matters of mutual interest under the Labour Relations Act. The High Court reviewed and set aside the agreement (save for one clause) on grounds of illegality. The bargaining council and associated parties appealed to the Supreme Court of Appeal, while the retirement funds cross-appealed.
