Tex. R. App. P. 49.3
As amended through February 20, 2024
A motion for rehearing may be granted by a majority of the justices who participated in the decision of the case. Unless two justices who participated in the decision of the case agree on the disposition of the motion for rehearing, the chief justice of the court of appeals must assign a justice to replace any justice who participated in the panel decision but cannot participate in deciding the motion for rehearing. If rehearing is granted, the court may dispose of the case with or without rebriefing and oral argument.
