Sec. 22.001. JURISDICTION

(a) The supreme court has appellate jurisdiction, except in criminal law matters, coextensive with the limits of the state and extending to all questions of law arising in the following cases when they have been brought to the courts of appeals from appealable judgment of the trial courts:

(1) a case in which the justices of a court of appeals disagree on a question of law material to the decision;

(2) a case in which one of the courts of appeals holds differently from a prior decision of another court of appeals or of the supreme court on a question of law material to a decision of the case;

(3) a case involving the construction or validity of a statute necessary to a determination of the case;

(4) a case involving state revenue;

(5) a case in which the railroad commission is a party; and

(6) any other case in which it appears that an error of law has been committed by the court of appeals, and that error is of such importance to the jurisprudence of the state that, in the opinion of the supreme court, it requires correction, but excluding those cases in which the jurisdiction of the court of appeals is made final by statute.

(b) A case over which the court has jurisdiction under Subsection (a) may be carried to the supreme court either by writ of error or by certificate from the court of appeals, but the court of appeals may certify a question of law arising in any of those cases at any time it chooses, either before or after the decision of the case in that court.

(c) An appeal may be taken directly to the supreme court from an order of a trial court granting or denying an interlocutory or permanent injunction on the ground of the constitutionality of a statute of this state. It is the duty of the supreme court to prescribe the necessary rules of procedure to be followed in perfecting the appeal.

(d) The supreme court has the power, on affidavit or otherwise, as the court may determine, to ascertain the matters of fact that are necessary to the proper exercise of its jurisdiction.

(e) For purposes of Subsection (a)(2), one court holds differently from another when there is inconsistency in their respective decisions that should be clarified to remove unnecessary uncertainty in the law and unfairness to litigants.
