This case provides authoritative guidance on the doctrine of legitimate expectation in South African administrative law, particularly: (1) setting out the minimum requirements for invoking legitimate expectation (clear/unambiguous representation, reasonableness, inducement by decision-maker, lawful competence); (2) emphasizing that reasonableness operates as a pre-condition to legitimacy, requiring an objective test; (3) confirming that subjective confusion or misinterpretation cannot create legitimate expectation; (4) reaffirming fundamental principles of motion court procedure regarding disputes of fact, extending the Plascon-Evans test but emphasizing its limits; (5) warning against courts bypassing statutory authorities vested with decision-making responsibilities; (6) leaving open the question whether legitimate expectation can found substantive (as opposed to procedural) entitlements, noting this is a 'difficult and complex' issue that may involve problems peculiar to English law.
