A decision taken pursuant to a valid affirmative action measure that meets the requirements of section 9(2) of the Constitution and section 6(2)(a) of the Employment Equity Act does not constitute unfair discrimination. Measures under section 9(2) are not exceptions to the right to equality but form part of substantive equality. Once an affirmative action measure passes the three-pronged Van Heerden test (targeting persons disadvantaged by unfair discrimination, designed to protect or advance such persons, and promoting the achievement of equality), the implementation of that measure must still be lawful, rational, and consistent with the purpose of the measure and the Act. The implementation of a valid affirmative action plan may be challenged, but at a minimum it must be rationally related to the terms and objects of the measure. A party may not raise a new cause of action for the first time on appeal where it was not pleaded in the court of first instance, particularly where this would prejudice the other party. In the context of employment equity, a decision-maker with discretion to make appointments may lawfully decline to appoint a candidate from a non-designated group where that group is already over-represented at the relevant level, provided the decision is taken in accordance with the applicable plan and criteria, and is rationally connected to the goal of achieving representivity.
