In order that the error may invalidate the consent, it must refer to the substance of the thing, which may be the object of the contract, or to those conditions of the same, which should have been principally the cause of its execution.\nAn error with regard to the person shall invalidate a contract only when the consideration of the person should have been the principal cause of the same.\nA mere error of account shall only give rise to its correction.\nHistory\n—Civil Code, 1930, § 1218.
