The doctrine of mistake in contract law has had a chequered history. Indeed, its very existence has been questioned (see, e.g., Slade, (1954) 70 L.Q.R. 385 and Atiyah and Bennion, (1961) 24 M.L.R. 421). But, like a bad penny that will not go away, the doctrine remains stubbornly embedded in the contractual landscape and has in fact witnessed a small revival of sorts in recent years (see, e.g., Clarion Ltd. v. National Provident Institution [2000] 2 All E.R. 265 (noted Phang, (2002) 1 J.O.R. 21)).
