California Code, Civil Code - CIV § 1692

When a contract has been rescinded in whole or in part, any party to the contract may seek relief based upon such rescission by (a) bringing an action to recover any money or thing owing to him by any other party to the contract as a consequence of such rescission or for any other relief to which he may be entitled under the circumstances or (b) asserting such rescission by way of defense or cross-complaint.

If in an action or proceeding a party seeks relief based upon rescission and the court determines that the contract has not been rescinded, the court may grant any party to the action any other relief to which he may be entitled under the circumstances.

A claim for damages is not inconsistent with a claim for relief based upon rescission. The aggrieved party shall be awarded complete relief, including restitution of benefits, if any, conferred by him as a result of the transaction and any consequential damages to which he is entitled; but such relief shall not include duplicate or inconsistent items of recovery.

If in an action or proceeding a party seeks relief based upon rescission, the court may require the party to whom such relief is granted to make any compensation to the other which justice may require and may otherwise in its judgment adjust the equities between the parties.
