The right to receive education in an official language of choice under section 29(2) is subject to the qualification of 'reasonable practicability', which requires a context-sensitive analysis involving both factual and normative constitutional elements. The test of 'reasonable practicability' for conferring the right and 'appropriate justification' for diminishing it once enjoyed are essentially synonymous - both require consideration of equity, practicability, and the need to redress past racially discriminatory laws and practices. A public educational institution may legitimately diminish (but not eliminate) instruction in a previously privileged language where: (1) maintaining full instruction in that language creates barriers to access and feelings of exclusion/stigmatization for students not conversant in it; (2) the cost of avoiding such diminution while maintaining full access is substantial and not reasonably practicable given other institutional needs; and (3) the decision is made through a proper, thorough, inclusive and deliberative process. Cost is a legitimate consideration in determining what is 'reasonably practicable', and courts should give appropriate respect to institutional judgments on cost-benefit analyses, though not deference to unreasonable decisions. White Afrikaans-speakers, because of their historically and currently privileged position, cannot demand the same treatment as historically disadvantaged linguistic minorities.
