(a) A convicting court may order forensic DNA testing under this chapter only if:
(1) the court finds that:
(A) the evidence:
(i) still exists and is in a condition making DNA testing possible; and
(ii) has been subjected to a chain of custody sufficient to establish that it has not been substituted, tampered with, replaced, or altered in any material respect;
(B) there is a reasonable likelihood that the evidence contains biological material suitable for DNA testing; and
(C) identity was or is an issue in the case; and
(2) the convicted person establishes by a preponderance of the evidence that:
(A) the person would not have been convicted if exculpatory results had been obtained through DNA testing; and
(B) the request for the proposed DNA testing is not made to unreasonably delay the execution of sentence or administration of justice.
(b) A convicted person who pleaded guilty or nolo contendere or, whether before or after conviction, made a confession or similar admission in the case may submit a motion under this chapter, and the convicting court is prohibited from finding that identity was not an issue in the case solely on the basis of that plea, confession, or admission, as applicable.

(b-1) Notwithstanding Subsection (c), a convicting court shall order that the requested DNA testing be done with respect to evidence described by Article 64.01(b)(2)(B) if the court finds in the affirmative the issues listed in Subsection (a)(1), regardless of whether the convicted person meets the requirements of Subsection (a)(2). The court may order the test to be conducted by any laboratory that the court may order to conduct a test under Subsection (c).
(c) If the convicting court finds in the affirmative the issues listed in Subsection (a)(1) and the convicted person meets the requirements of Subsection (a)(2), the court shall order that the requested forensic DNA testing be conducted. The court may order the test to be conducted by:
(1) the Department of Public Safety;
(2) a laboratory operating under a contract with the department; or
(3) on the request of the convicted person, another laboratory if that laboratory is accredited under Article 38.01.
(d) If the convicting court orders that the forensic DNA testing be conducted by a laboratory other than a Department of Public Safety laboratory or a laboratory under contract with the department, the State of Texas is not liable for the cost of testing under this subsection unless good cause for payment of that cost has been shown. A political subdivision of the state is not liable for the cost of testing under this subsection, regardless of whether good cause for payment of that cost has been shown. If the court orders that the testing be conducted by a laboratory described by this subsection, the court shall include in the order requirements that:
(1) the DNA testing be conducted in a timely and efficient manner under reasonable conditions designed to protect the integrity of the evidence and the testing process;
(2) the DNA testing employ a scientific method sufficiently reliable and relevant to be admissible under Rule 702, Texas Rules of Evidence; and
(3) on completion of the DNA testing, the results of the testing and all data related to the testing required for an evaluation of the test results be immediately filed with the court and copies of the results and data be served on the convicted person and the attorney representing the state.
(e) The convicting court, not later than the 30th day after the conclusion of a proceeding under this chapter, shall forward the results to the Department of Public Safety.
