Tex. R. Jud. Admin. 14.6

As amended through August 27, 2024
Rule 14.6 - Transfer and Consolidation of Related Cases
(a) "Related case" means any case in which the state or a state officer or agency is a defendant that arises from the same nucleus of operative facts as the case before a special three-judge district court, regardless of the legal claims or causes of action asserted in the related case.
(b) On the motion of any party to a case assigned to a special three-judge district court, the special three-judge district court must transfer a related case to itself and consolidate the related case with the case before the court. The special three-judge district court may transfer a related case without the consent of the parties to the related case or of the court in which the related case is pending.
(c) The motion must be in writing and include:
(1) the cause number, style, court, and name of the judge of the court in which the related case is pending;
(2) a list of parties and counsel in the related case and complete contact information for all counsel;
(3) a demonstration that the related case arises from the same nucleus of operative facts as the case before the special three-judge district court;
(4) the live pleadings on file in the related case; and
(5) a certificate of service on all parties to the case pending before the special three-judge district court and to the related case.
(d) After a motion to transfer and consolidate a related case is filed, the special three-judge district court or the court in the related case may stay the proceedings in the case before it until the special three-judge district court has ruled on the motion.
