 De Villiers, however, refused to concede the point, so that the dispute continued until 1919, almost 50 years after it began, it was settled by the Appellate Division of the South African Supreme Court in the famous case of "Conradie v Rossouw", where the court took the Transvaal view that a binding contract may be constituted by any serious and deliberate agreement made with the intention of creating a legal obligation, and in so doing, simultaneously abolished the "iusta causa" and consideration doctrines.It seems now to be clear that a "causa", be it onerous ("ex titulo oneroso") or gratuitous ("ex causa lucrativa"), is not a separate requirement in the South African law of contract.‘That a contract, in order to be valid, must have been seriously intended by the parties [as well as the other obvious elements such as lawful and performable], is a matter of course ... [and] does not need "causa" as an independent element’.
