Tex. R. App. P. 49.5
A party may file a motion for en banc reconsideration as a separate motion, with or without filing a motion for rehearing. The motion must be filed within the time prescribed by Rule 49.1 for filing a motion for rehearing. The motion should address the standard for en banc consideration in Rule 41.2(c). No response to a motion for en banc reconsideration need be filed unless the court so requests. While the court has plenary power, a majority of the en banc court may, on its own initiative, order en banc reconsideration of a decision. If a majority orders reconsideration, the judgment or order does not become final, and the case will be resubmitted to the court for en banc review and disposition. The court may dispose of the case with or without rebriefing and oral argument.
