When the nullity proceeds from the illegality of the cause or object of the contract, and the act constitutes a criminal offense, both parties being in pari delicto, they shall have no action against each other, and both shall be prosecuted. Moreover, the provisions of the Penal Code relative to the disposal of effects or instruments of a crime shall be applicable to the things or the price of the contract.
This rule shall be applicable when only one of the parties is guilty; but the innocent one may claim what he has given, and shall not be bound to comply with his promise. (1305)
