A Roberts and Co Ltd v Leicestershire County Council: ChD 1961

The court considered the circumstances required for rectification of a contract after a unilateral mistake. Pennycuick J said: ‘a party is entitled to rectification of a contract upon proof that he believed a particular term to be included in the contract, and that the other party concluded the contract with the omission or a variation of that term in the knowledge that the first party believed the term to be included. . . The principle is stated in Snell on Equity, 25th edition (1960), p 569 as follows: ‘By what appears to be a species of equitable estoppel, if one party to a transaction knows that the instrument contains a mistake in his favour but does nothing to correct it, he (and those claiming under him) will be precluded from resisting rectification on the ground that the mistake is unilateral and not common.”
