Tex. Gov't Code § 432.112

At any time within two years after approval by the convening authority of a court-martial sentence, the accused may petition the state judge advocate general for a new trial on ground of newly discovered evidence or fraud on the court-martial. If the accused's case is pending before the Texas Court of Military Appeals when the petition is filed, the appeal does not proceed until the state judge advocate general has made a decision on the request. If the petition is granted, the appeal shall be dismissed. If the petition is denied, the court of military appeals shall continue its proceedings on the case.
