(14)This Directive should not affect national law in the area of contract law for contract law aspects that are not regulated by this Directive. Therefore, this Directive should be without prejudice to national law regulating for instance the conclusion or the validity of a contract (for instance in the case of lack of consent). Similarly, this Directive should not affect national law in relation to the general contractual legal remedies, the rules on public economic order, for instance rules on excessive or extortionate prices, and the rules on unethical legal transactions.
