As a matter of contract law, in cases in which the party that breaches the contract is found to have committed a major breach, one which goes to the very heart of the contract and which deprives the innocent party of substantially all that they were entitled to expect under the contract, what remedy or remedies are potentially open to that party?

As a matter of contract law, if a party to a contract is induced to enter into that contract by either a fraudulent or negligent misrepresentation made by (or on behalf of) the other party to that contract, is that contract either void or voidable?
