The Natal Joint Municipal Pension Fund, a registered pension fund for municipal employees in KwaZulu-Natal, sought to recover an adjusted employer contribution from the Endumeni Municipality following the resignation of a senior employee, Mr Bart Maltman. Through lawful fund-switching and salary adjustments, Mr Maltman became entitled to a large withdrawal benefit that was actuarially underfunded. The Fund relied on a proviso inserted into the Superannuation Fund regulations in 2004, empowering the Fund’s management committee, on actuarial advice, to direct a municipality to pay an adjusted contribution where pensionable emoluments increased beyond actuarial assumptions. Endumeni resisted liability, arguing that the proviso was invalid due to late registration under the Pension Funds Act, that it did not apply on a proper interpretation, and that procedural requirements for invoking it were not met.
