The Government Employees Pension Fund (GEPF) is a pension fund established under the Government Employee Pension Law, 1996 (GEP law) to administer pensions for government employees. The Public Servants Association (PSA), a trade union representing over 237,000 public service members, along with two individual former members (Van Wyk and Olifant), challenged a decision by the GEPF Board of Trustees taken on 3 December 2014. The decision amended the F(Z) and A(X) actuarial interest factors used in calculating pension benefits under Rule 14.4.2 of the GEPF Rules, effective from 1 April 2015. The amendment reduced benefits for members whose membership terminated after that date. Rule 14.4.2 requires that such factors be determined "by the Board acting on the advice of the actuary, and after consultation with the Minister [of Finance] and the employee organisations." The GEPF did not consult with the PSA or any employee organisations before making the decision. The PSA only became aware of the decision in July 2015 when members began querying reduced benefits. For example, one member's benefit was reduced from R2,547,716 to R2,399,206 (a reduction of R148,510 or 5.8%). The GEPF subsequently attempted post-decision "consultation" through the Public Service Co-ordinating Bargaining Council (PSCBC) in meetings held in September and December 2015. The PSA challenged this as inadequate and launched a review application in July 2016 in the Gauteng High Court. The High Court (Van der Westhuizen J) dismissed the application with costs, finding that consultation could occur after the decision and that the PSCBC process satisfied the consultation requirement. The PSA appealed to the Supreme Court of Appeal with leave.
