Ms Catherine Brown sold her Sea Point property to Groundswell Developments Africa (Pty) Ltd under an agreement of sale brokered by Mr Jean Pierre Nortje, who acted as her estate agent while being the alter ego of the purchaser. Nortje failed to disclose his personal interest, lacked a valid fidelity fund certificate at the time, and misrepresented material aspects of the transaction. Groundswell, through Nortje, obtained occupation purportedly to effect limited repairs but instead undertook extensive renovations via Horizon Group (Pty) Ltd, another Nortje-controlled entity, without Brown’s knowledge or consent. Horizon claimed a builder’s lien based on a renovation agreement unknown to Brown. After discovering these facts, Brown cancelled the agreement of sale. The High Court declared the agreement of sale invalid, the builder’s lien void, and ordered eviction. Leave to appeal was refused, and the applicants sought reconsideration under s 17(2)(f) of the Superior Courts Act.
