OPINION
KEASLER, J.,delivered the opinion of the Court,
which McCORMICK, P.J., and MEYERS, MANSFIELD, KELLER, PRICE, HOLLAND, and WOMACK, J.J., joined.The court of appeals affirmed Enrique Lopez’s conviction but remanded the case to the trial court because of error in the punishment phase of trial. After sentence was pronounced on remand, Lopez filed a motion for new trial alleging error at the guilt-innocence phase of his first trial. We must decide whether the trial court had jurisdiction to consider this motion. We conclude that it did not.
Procedural History
Lopez was initially convicted of attempted capital murder and sentenced to 50 years in prison. The court of appeals held that the trial court erred in allowing an unqualified reputation witness to testify at the punishment phase of trial, and concluded that the error harmed Lopez.1 The *639court of appeals reversed the punishment verdict and remanded the case for a new punishment hearing.2 On remand, Lopez was sentenced to life in prison. He again appealed, and this time the court of appeals held the trial court erred in admitting evidence of an extraneous offense, and the error harmed Lopez.3 The court again remanded for a new punishment hearing.4
On second remand, Lopez was sentenced to 99 years in prison. Within BO days of this sentence, Lopez filed a motion for new trial claiming, among other things, that he received ineffective assistance of counsel at the guilt/innocence phase of his first trial and he received ineffective assistance of counsel on his first appeal for counsel’s failure to adequately brief the claim regarding trial counsel’s ineffectiveness. The trial court denied the motion.
Lopez appealed, arguing that the trial court erred in denying the motion for new trial because he had demonstrated that he had been denied effective assistance of counsel at the guilt/innocence phase of his original trial and on his first appeal. The court of appeals overruled Lopez’s points of error,5 relying in part on Davila v. State6 and Easton v. State.7 In those cases, the courts of appeals held that upon remand for punishment only, a trial court has no power to grant a new trial based on errors allegedly occurring at the guilt/innocence phase. We granted Lopez’s petition for discretionary review, which asks whether a trial court has jurisdiction to consider a motion for new trial when a case is remanded for punishment only.
Analysis
A timely filed notice of appeal vests a court of appeals with jurisdiction over the case.8 Once the court of appeals obtains jurisdiction, the trial court loses jurisdiction.9 The trial court cannot thereafter regain jurisdiction unless the court of appeals returns the case to that court.10
The Rules of Appellate Procedure permit a court of appeals to remand a case on punishment only.11 When it does so, it is essentially affirming the conviction on guiltyinnocence and reversing the conviction on punishment. In such a case, we conclude the trial court’s jurisdiction on remand is limited to issues concerning the punishment phase.
In this case, the court of appeals remanded the case to the trial court for punishment only. By doing so, it affirmed the guilt-innocence portion of the trial. As a result, the trial court no longer had any jurisdiction over that portion of the trial, and had no jurisdiction to consider Lopez’s motion for new trial concerning the guilt-innocence portion of the trial.
Lopez argues that the language of Art. 44.29(b) requires the opposite result. That statute provides, in pertinent part, as follows:
*640If the court of appeals or the Court of Criminal Appeals awards a new trial to a defendant ... only on the basis of an error or errors made in the punishment stage of the trial, the cause shall stand as it would have stood in case the new trial had been granted by the court below, except that the court shall commence the new trial as if a finding of guilt had been returned and proceed to the punishment stage of the trial ...
According to Lopez, when the court of appeals remanded his case on punishment, the cause stood “as it would have stood in case the new trial had been granted by the court below, except that the court shall commence the new trial as if a finding of guilt had been returned and proceed to the punishment stage of trial.” Lopez explains that once the case proceeded to the punishment stage and the trial court assessed sentence, the Rules of Appellate Procedure came into play. Those Rules, Lopez argues, provide that a motion for new trial may be filed within 30 days from the date the trial court imposes sentence.12 So according to Lopez, once sentence was pronounced on remand, he was entitled under the Rules of Appellate Procedure to file a motion for new trial alleging error at guilt/innocence.
But Lopez’s argument defeats itself. If the language of Art. 44.29 is to be construed literally, then the case is placed back in the position it would have stood “in case the new trial had been granted by the court below.” So we would have to suppose that the trial court has already granted a motion for new trial, but the court commences that new trial as if a finding of guilt had already been returned. In such a case, there is no reason for a defendant to file another motion for new trial based upon the events occurring at his first trial. Once the initial motion for new trial is granted, any subsequent motion for new trial based on the same events would be superfluous.
In addition, Lopez’s theory would render Art. 44.29 meaningless. That is, the statute was enacted in order to give an appellate court the authority to remand a case on punishment only.13 If, after remand, the trial court has the authority to reconsider issues from the guilt-innocence portion of the trial, the appellate court’s remand “on punishment only” is rendered meaningless. We believe that to give effect to Art. 44.29(b), a remand on punishment only must limit a trial court’s jurisdiction to only punishment issues.
Finally, when the Legislature granted this Court rule-making authority, it expressly provided that the rules could not abridge, enlarge, or modify the substantive rights of a litigant.14 Lopez would use a rule of appellate procedure, Rule 21.4, to enlarge upon the substantive rights of a litigant provided by the Legislature in Art. 44.29. This we cannot do.
Conclusion
We conclude that when a court of appeals remands a case to the trial court on punishment only, the trial court’s jurisdiction on remand is limited to punishment issues. The trial court has no jurisdiction at that point to entertain a motion for new trial which complains of error occurring at the guilt-innocence phase of the trial.
We affirm the decision of the court of appeals.
