The remedy of rescission is, in principle, available for all classes of operative misrepresentation. When a person has been induced to enter into a contract by a misrepresentation of any description, the effect on the contract is not to make it void, but to give the misled party an option either to avoid it or, alternatively, to affirm it.26
Rescission, however, is not merely a judicial remedy. The misled party can rescind WITHOUT seeking the assistance of the Court, and any property transferred to the representor under the contract will revest in the party who has so rescinded the contract. As a normal rule, rescission must be communicated to the other party.26A
However, under Section 2(2) of the U.K. Misrepresentation Act 1967, and under Section 45(2) of the Irish Sale of Goods and Supply of Services Act 1980:
Where a person has entered into a contract after a misrepresentation has been made to him otherwise than fraudulently, and he would be entitled by reason of the representation to rescind the contract, then, if it is claimed in any proceedings arising out of the contract that the contract ought to be or has been rescinded, the court or arbitrator may declare the contract subsisting and award damages in lieu of rescission, if of the opinion that it would be equitable to do so.
