(After stating the foregoing facts.) It is always the duty of this court, with or without motion of a party) to consider the question of its jurisdiction in all cases in which there may be any doubt as to the existence of such jurisdiction; and the present case is one calling for such inquiry.

A proceeding to confirm and validate revenue-anticipation certificates is one which falls within the jurisdiction of the Court of Appeals and not the Supreme Court. Code (Ann. Supp.), §§ 2-3704, 2-3708;

(a) “The Court of Appeals has jurisdiction to decide questions of law that involve application, in a general sense, of unquestioned and unambiguous provisions of the Constitution to a given state of facts, and that do not involve construction of some constitutional provision directly in question and doubtful either under its own terms or under the decisions of the Supreme Court of the State or

of the United States.”

(b) Are the allegations of the intervention sufficient to draw into question the constitutionality of the act of 1937 (Ga. L. 1937, p. 761), or any part thereof? We think not. It is a grave matter for this court to set aside an act of the co-ordinate legislative department, and vague and indefinite attacks can not be considered.
Savannah, Florida & Western Ry. Co.
v.
Hardin,

Ga.
433 (
*247 The plaintiff in error contends that jurisdiction is vested in this court by the Code, § 87-304, which provides that a dissatisfied party in a proceeding to confirm and validate bonds may bring the case to the Supreme Court for review. Conceding that the section did contain such a provision for review by this court, but not holding that it had the effect of doing so, the contention is incorrect because the provision of that section relating to review by the Supreme Court was superseded by the Constitution of 1945, defining the jurisdiction respectively of the Supreme Court and the Court of Appeals. Code (Ann. Supp.), §§ 2-3704, 2-3708; Payne v. State, supra.
From what has been said, it follows that the Court of Appeals and not this court has jurisdiction.
Transferred to the Court of Appeals.
