This case is significant in South African administrative law for clarifying the temporal scope of the Oudekraal Estates principle. It establishes that while the 'second actor' analysis may preserve the validity of acts performed consequent upon an invalid administrative decision pending review, once that initial decision is set aside by a competent court, all acts depending on it for validity are rendered of no force or effect. The case emphasizes that the Oudekraal analysis relates to the validity of consequent acts only for so long as the initial act has not been set aside, and does not bear on whether the initial act should be set aside. The judgment also clarifies that a court has discretion in judicial review proceedings whether to set aside an invalid administrative act, considering factors such as lapse of time, finality, public interest and reliance. The decision confirms that acts performed to implement an invalid decision (such as executing powers of attorney and registering servitudes) are not separate 'decisions' requiring independent review, but share the fate of the underlying decision once it is set aside.
