Tex. Bus. & Com. Code § 17.43
The provisions of this subchapter are not exclusive. The remedies provided in this subchapter are in addition to any other procedures or remedies provided for in any other law; provided, however, that no recovery shall be permitted under both this subchapter and another law of both damages and penalties for the same act or practice. A violation of a provision of law other than this subchapter is not in and of itself a violation of this subchapter. An act or practice that is a violation of a provision of law other than this subchapter may be made the basis of an action under this subchapter if the act or practice is proscribed by a provision of this subchapter or is declared by such other law to be actionable under this subchapter. The provisions of this subchapter do not in any way preclude other political subdivisions of this state from dealing with deceptive trade practices.
