The Associated Institutions Pension Fund and Others v Johan van Zyl and Others

The Associated Institutions Pension Fund (AIPF), established under the Associated Institutions Pension Fund Act 41 of 1963, provided pension benefits to employees of associated institutions such as universities. During 1994–1995, many institutions, including the University of Pretoria, established their own pension funds, and employees elected to transfer their pension interests from the AIPF pursuant to transfer regulations promulgated under the Act. The respondents, employees of the University of Pretoria, transferred their benefits as at 31 December 1994. In terms of the regulations, the transfer value depended on a ‘funding percentage’ determined by the AIPF’s actuary, Mr Leon de Wit. De Wit determined the funding percentage at 60%, using actuarial estimates and projections rather than fully audited data. Nearly four years later, the respondents sought judicial review of this determination, alleging that the actuary acted ultra vires the regulations by failing to use actual market values of assets, resulting in a shortfall in transferred amounts.

The appeal was upheld. The judgment and orders of the Pretoria High Court were set aside, and the respondents’ review application was dismissed with costs.

The case affirms that actuarial determinations under pension legislation may lawfully involve estimates, assumptions and projections consistent with actuarial practice. It reinforces the authority of the SCA’s earlier decision in the Unisa case and provides important guidance on statutory interpretation in the context of pension fund transfers and administrative review.
