Tex. R. App. P. 56.3
If a case is settled by agreement of the parties and the parties so move, the Supreme Court may grant the petition if it has not already been granted and, without hearing argument or considering the merits, render a judgment to effectuate the agreement. The Supreme Court's action may include setting aside the judgment of the court of appeals or the trial court without regard to the merits and remanding the case to the trial court for rendition of a judgment in accordance with the agreement. The Supreme Court may abate the case until the lower court's proceedings to effectuate the agreement are complete. A severable portion of the proceeding may be disposed of if it will not prejudice the remaining parties. In any event, the Supreme Court's order does not vacate the court of appeals' opinion unless the order specifically provides otherwise. An agreement or motion cannot be conditioned on vacating the court of appeals' opinion.
