delivered the .opinion of the Court.
This proceeding was commenced by a petition filed by the plaintiffs in error on the law side of the Federal District Court for Eastern Kentucky, seeking to obtain a judgment declaring their rights under an Act of the Kentucky Legislature.
The Declaratory Judgment Law of Kentucky, Acts of 1922, ch. 83, provides that in any action in a court of record of that Commonwealth having general jurisdiction wherein it is made to appear that an actual controversy exists, the plaintiff may, by means óf a petition on the law or equity side of the court, as the nature of the case may require, ask for and obtain “ a declaration of rights, either alone or with other relief; and the court may make a binding declaration of'rights, whether or not consequential relief is or could be asked; ” and that further relief, based on such declaratory judgment, maybe granted by the court whenever necessary or proper, either in the same proceeding or in an independent action, upon notice to any adverse party whose rights have been adjudicated by the declaratory judgment.
The plaintiffs prayed the court “by its judgment'to declare what their rights and duties under said Act of 1924 are, and that a judgment be rendered declaring said Act of 1924 invalid, and for all proper relief.”
The defendant demurred to the petition, on the ground, among others, -that the court had no jurisdiction of the cause of action set forth, having no power or authority as a Federal Court to entertain a proceeding for á declarar tion of the rights of parties or to act under the provisions of the Declaratory Judgment - Law of Kentucky. This demurrer was sustained. Twelve days later a final judgment was entered, reciting that the plaintiffs having failed to amend their petition, and the court being of opinion that it had no jurisdiction of the action, the same was dismissed. . This direct writ of error was allowed upon the question of jurisdiction, under § 238 of the Judicial Code, before the amendment made by the Jurisdictional Act of 1925 became effective.
The sole purpose of the petition, as shown by its express allegations, is to obtain a declaration from the District Court-of the rights and duties of the plaintiffs under the Act of 1924, and a determination of the extent to which they must comply with its provisions in the conduct of their business. ■ This is its entire scope. While the Commonwealth Attorney is made a defendant as a representative of the Commonwealth, there is no semblance of any adverse litigation with him individually; there being neither any allegation that the plaintiffs have done or .contemplate doing any of the things forbidden by the Act before being advised by the court as to their rights, nor any allegation - that the Commonwealth Attorney has threatened to take or contemplates taking any action against them for any violation of the Act, either past or prospective. And no relief of any kind is prayed against him, by restraining action on his part or otherwise,
We need not review these at length. It suffices to say that in the light of the decisions in

in which it was held that it was not within the constitutional authority of this Court to entertain an appeal from the Court of Claims in a suit brought, under a permissive act of Congress, by members of the Cherokee Tribe of Indians to determine the constitutional validity of certain congressional enactments, the Court, in an extended opinion reviewing the earlier
And.in
New Jersey
v.
Sargent, supra,

It' follows necessarily from these decisions that the District Court, as a court of the United States established under Article III of the Constitution, had no jurisdiction to entertain the petition for the declaratory judgment.
Manifestly the Federal Conformity Statute, R. S. § 914 (U. S. Code, Tit. 28, § 724) conferred upon the court no jurisdiction to proceed in accordance with the Declaratory Judgment Law of Kentucky. This' statute relates only to “practice, pleadings, and forms and modes of procedure; ” and neither purports to nor can extend the jurisdiction of the district courts beyond the constitutional limitations. See
Southern Pacific Co.
v.
Denton,
The plaintiffs in error also rely in argument here upon § 274a of the Judicial Code (U. S. Code, Tit. 28, § 397), which provides that on finding that a suit at law should have been brought in equity, or vice versa, the court shall order any amendments to the pleadings which may be necessary to conform to the proper practice, and that any party may amend his pleadings so as to obviate the objection that his suit was not brought on the right side of the court. This statute relates merely to a case in which the objection is to the side of the court on which the suit is brought, and not to the entire lack of jurisdiction in the court. It is plain that it has no application here, where the court was without jurisdiction to entertain the petition for a declaratory judgment either upon the equity or the law side.
Affirmed.
