Tex. R. App. P. 47.2

As amended through August 27, 2021
Rule 47.2 - Designation and Signing of Opinions; Participating Justices
(a)Civil and Criminal Cases. Each opinion of the court must be designated either an "Opinion" or a "Memorandum Opinion." A majority of the justices who participate in considering the case must determine whether the opinion will be signed by a justice or will be per curiam and whether it will be designated an opinion or memorandum opinion. The names of the participating justices must be noted on all written opinions or orders of the court or a panel of the court.
(b)Criminal Cases. In addition, each opinion and memorandum opinion in a criminal case must bear the notation "publish" or "do not publish" as determined - before the opinion is handed down - by a majority of the justices who participate in considering the case. Any party may move the appellate court to change the notation, but the court of appeals must not change the notation after the Court of Criminal Appeals has acted on any party's petition for discretionary review or other request for relief. The Court of Criminal Appeals may, at any time, order that a "do not publish" notation be changed to "publish."
(c)Civil Cases. Opinions and memorandum opinions in civil cases issued on or after January 1, 2003 shall not be designated "do not publish."
