The appellant was employed by the Building Industrial Bargaining Council (BIBC) from 17 October 1977 and was a member of the Fedsure Staff Pension Fund (the Fund). In March 2002, Investec acquired Fedsure Holdings Limited, which was the employer as defined in the Fund's rules. Investec notified BIBC and other participants that the Fund would no longer accept contributions from them with effect from 1 July 2002. BIBC accepted this and ceased contributions from 1 July 2002, making alternative arrangements to join the Wizard Universal Pension Fund (WUPF). The Fund applied to the Registrar for approval to transfer benefits to WUPF under s 14(1) of the Pension Funds Act 24 of 1956, effective 1 July 2002. The transfer was approved on 9 July 2004 with retrospective effect to 1 July 2002. The appellant was retrenched on 30 June 2003, after which WUPF paid him R2,120,153 as pension benefits. The appellant claimed he was entitled to enhanced pension benefits under Rule 8 of the Fund's rules totaling R2,649,460, demanding the shortfall of R529,307 from the Fund or his employer. The appellant argued he acquired a vested right to enhanced benefits when retrenched on 30 June 2003, which could not be affected by the retrospective transfer approval.
