The appellant, a registered pension fund, applied to the Registrar of Pension Funds for approval and registration of an amendment to its rules under s 12 of the Pension Funds Act 24 of 1956. The amendment made the payment of certain historically guaranteed retirement benefits conditional upon the relevant employer funding those benefits. This arose from significant deficits linked to guarantees inherited from predecessor funds (AIPF and TEPF) and the introduction of statutory minimum benefits on early withdrawal under s 14A, which created an additional unfunded liability. The Registrar refused to approve and register the amendment, primarily because it reduced benefits and shifted responsibility to employers. The Board of Appeal and the Pretoria High Court upheld the refusal. The fund then appealed to the Supreme Court of Appeal.
