When a decision on an appeal is reversed and remanded, what is the next step?

The court to which the matter is remanded will schedule a session in court to set the case management. If you are one of the litigants, you should get notice. See the clerk of the court to which the remand order issued. Good luck.

It depends. Assuming you are in a Texas intermediate court of appeals, one side or the other might file a motion for rehearing, which would delay finality. Or one side or the other could pursue a petition for review in the Texas Supreme Court. Otherwise, the next step is for the appellate court to issue its mandate. The mandate is the official notice of the appellate court’s action, directed to the court below, advising the lower court of the appellate court’s action and directing that court to have the appellate court’s judgment duly recognized, obeyed, and executed.
