The appellants were joint liquidators of Nomic 151 (Pty) Ltd (in liquidation). They concluded a written agreement on 14 November 2016 to sell several erven in Mossel Bay, including a ring road erf (erf 19565), to the respondent, Curro Heights Properties (Pty) Ltd, for R4.5 million plus VAT. The agreement incorrectly described the ring road’s erf number, although both parties initially intended to deal with erf 19565. After delays in payment and transfer, an addendum was signed on 18 April 2017 extending the transfer date. During preparation for transfer, it emerged that erf 19565 extended into a neighbouring development (Nurture Park). Curro then contended that it never intended to purchase that portion and proposed subdivision of the ring road. No written and signed addendum dealing with subdivision was concluded. After prolonged delays and failed negotiations, the liquidators cancelled the agreement and sought declaratory relief that the sale was void for lack of consensus on the merx and for non-compliance with s 2(1) of the Alienation of Land Act 68 of 1981. The High Court dismissed the application, and the liquidators appealed to the Supreme Court of Appeal.
