The court made obiter observations on several matters: (1) Constitutional issues regarding freedom of association, freedom of trade, occupation and profession, and fair labour practices were raised by MEPF but not pursued on appeal beyond relying on the Constitution to interpret the legislation consistently therewith. The court noted that the decision to impose restricted choice on municipal employees appeared to enhance pension benefits and cost effectiveness. (2) The court discussed MEPF's argument that repeal of section 79quat of Local Government Ordinance 17 of 1939 (Transvaal) by section 58 of the Rationalisation of Local Government Affairs Act 10 of 1998 (Gauteng) enabled MEPF to operate on a broader geographic scale. The court stated: 'The notion that the repeal of the original empowering provision, which is still referred to in the appellant's rules, had the effect of enabling it to operate on a broader scale than previously is certainly unusual.' However, the court declined to reach a definitive conclusion on this point, stating it 'requires a more careful consideration of the statutory provisions governing pension funds and we have not had the detailed argument on the point that would permit us to reach a firm conclusion one way or the other.' (3) The court observed that economies of scale and critical mass are crucial considerations for pension fund viability, noting that 'A large pool of members result in economies of scale and this reduces the overall costs.' (4) The court noted that permitting employees to join multiple funds generates additional administrative obligations and costs for employers.
