rescission of a contract

A unilateral mistake is therefore in principle no ground for rescission of a contract.

So section 2(2) gives the court a discretion about whether it will allow rescission of a contract, or substitute an appropriate award of damages in lieu (instead).

The Supreme Court also hears cases involving claims for equitable relief, such as injunctions, specific performance, or rescission of a contract, as well as actions for a declaratory judgment.

Shogun Finance Ltd v Hudson [2003] UKHL 62 is an English contract law case decided in the House of Lords, on the subject of mistaken identity as a basis for rescission of a contract.
