UNISA, a historically bilingual (English and Afrikaans) distance-learning university, adopted a new language policy in 2016 which replaced its dual-medium policy with English as the sole language of learning and tuition. The policy was recommended by the Senate and approved by the Council in terms of the Higher Education Act and the national Language Policy for Higher Education. AfriForum NPC challenged these decisions, arguing that the removal of Afrikaans as a language of instruction was unconstitutional and unlawful. Initially relying partly on PAJA, AfriForum later confined its challenge to the principle of legality, contending that UNISA failed to show that it was not reasonably practicable to continue offering tuition in Afrikaans as required by s 29(2) of the Constitution. The High Court dismissed the application, and AfriForum appealed to the Supreme Court of Appeal.
