delivered the opinion of the Court-
Appellant brought suit in-the Chancery Court of Davidson County, Tennessee, under the Uniform Declara- ' tory Judgments Act of that state,1 c. 29, Tennessee Public Acts, 1923, to secure a judicial declaration that a state excise tax levied on the storage of gasoline, ,c. 58, Tennessee Public Acts, 1923, as amended by c. 67,. Tennessee •Public Acts, 1925, is, as applied to appellant, invalid under the commerce clause and the Fourteenth Amendment of the Federal Constitution. A decree for appellees was affirmed by the Supreme Court of the State, and the case coinés here on . appeal under § 237 (a) of the Judicial Code.
. In determining whether this litigation presents a case within the appellate jurisdiction of this Court, we are concerned, not with form, but with substance. See Fidelity National Bank v. Swope, 274 U. S. 123; compare Gasoline Products Co. v. Champlin Refining Co., 283 U. S. 494, 498. Hence, we look not to the label which the legislature has attached to the procedure followed in the state courts, or to the description of the judgment which is brought here for. review, in popular parlance, as “ declaratory,” but to the nature of the proceeding which the statute authorizes, and the effect of the judgment rendered upon the rights which the appellant asserts.
Section 1 of the Tennessee Declaratory Judgments Act confers jurisdiction on courts of record “ to declare rights .... whether or not further relief is or could be claimed ” and provides that “ no action or proceeding shall be open to objection on the ground that a declaratory judgment or decree is prayed for. The declaration may be either affirmative or negative in form and effect and such declaration shall have the force and effect of a final judgment or decree.” By § 2 it is provided that “ any person . . . whose rights, status or other legal relations are affected by a statute . . . may have determined any question of
Under § 6, the Court may refuse to render a declaratory judgment where, if rendered, "it “would not terminate the uncertainty or controversy giving rise to the proceeding.” Declaratory judgments may, in accordance with § 7, be reviewed as are other orders, judgments or-decrees, and under § 8 “ further relief based on a declaratory judgment or decree may be granted whenever necessary or proper.” Section 11 requires that “when declaratory relief is sought all persons shall be made parties who have dr claim, any interest- which would be affected by the declaration, and no declaration shall prejudice the rights of persons not parties to the proceeding.”
This statute has often been considered by the highest court of Tennessee, which has consistently held that its provisions may only be invoked when the- complainant' asserts rights which are challenged by the defendant, and presents for decision an actual controversy to which he is. a party, capable of final adjudication by the judgment or decree to be rendered. Miller v. Miller, 149 Tenn. 463; 261 S. W. 965; Goetz v. Smith, 152 Tenn. 451, 465; 278 S. W. 417; Hodges v. Hamblen County, 152 Tenn. 395; 277 S. W. 901; Cummings v. Shipp, 156 Tenn. 595; 3 S. W. (2d) 1062; Tennessee Eastern Electric Co. v. Hannah, 157 Tenn. 582, 587; 12 S. W. (2d) 372; Perry v. Elizabethton, 160 Tenn. 102, 106; 22 S. W. (2d) 359; Nashville Trust Co. v. Dake, 162 Tenn. 356, 359; 36 S. W. (2d) 905. It has also held that no judgment or decree will be rendered when all the parties who will be adversely affected by it are not before the Court. Harrell v. American Home Mortgage Co., 161 Tenn. 646; 32 S. W. (2d) 1023; Sadler v. Mitchell, 162 Tenn. 363, 367; 36 S. W. (2d) 891.
Proceeding in accordance with this statute, appellant' filed its bill of complaint in the state Chancery Court,
.. That the issues thus raised and judicially determined would constitute a case or controversy if raised and decided in a suit brought by the taxpayer to enjoin collection of the tax cannot be questioned. See Risty v. Chicago, R. I. & P. Ry. Co., 270 U. S. 378; compare Terrace v. Thompson, 263 U. S. 197; Pierce v. Society of Sisters, 268 U. S. 510; Euclid v. Ambler Realty Co., 272 U. S. 365. The proceeding terminating in the decree below, unlike that in South Spring Hill Gold Mining Co. v. Amador Medean Gold Mining Co., 145 U. S. 300; Muskrat v. United States, 219 U. S. 346, was bétween adverse parties, seeking a determination of their legal rights upon the facts alleged in the bill and admitted by the demurrer. Unlike Fairchild v. Hughes, 258 U. S. 126; Texas v. Interstate Commerce Commission, 258 U. S. 158; Massachusetts v.
While tjie ordinary course of judicial procedure results in a judgment requiring an award of process or execution to carry it into, effect, such relief is not an indispensable -adjunct to the exercise of the judicial function. Fidelity National Bank v. Swope, supra, 1932; This Court has often exerted its judicial power to adjudicate boundaries between states, although it gave no injunction or other relief beyond the determination of the legal rights which were the subject of controversy between the parties, Louisiana v. Mississippi, 202 U. S. 1; Arkansas v. Tennessee, 246 U. S. 158; Georgia v. South Carolina, 257 U. S. 516; Oklahoma v. Texas, 272 U. S. 21; Michigan v. Wisconsin, 272 U. S. 398, and to review judgments of the Court of Claims, although no process issues against the Government. United States v. Jones, 119 U. S. 477; compare District of Columbia v. Eslin, 183 U. S. 62; Ex parte Pocono Pines Hotels Co., 285 U. S. 526, reported below in 73 Ct. Cls. 447. As we said in Fidelity National Bank v. Swope, supra, 132, “ Naturalization.proceedings, Tutun v. United States, 270 U. S. 568; suits to determine a matrimonial or other status; suits for instructions to a trustee or for-the construction of a will; Traphagen v. Levy, 45 N. J. Eq. 448; 18 Atl. 222; bills of interpleader so far as the stakeholder is concerned, Wakeman v. Kingsland, 46 N. J. Eq. 113; 18 Atl. 680; bills to quiet title where the plaintiff rests his claim on adverse possession, Sharon v. Tucker, 144 U. S. 533; are familiar examples of judicial proceedings which result in an adjudication of the rights of litigants, although execution is not necessary to carry the judgment into effect, in the sense that damages are required to be paid or acts to be performed by the parties.” See also Old Colony Trust Co. v. Commissioner, supra, 725; La Abra Silver Mining Co. v. United States, 175 U. S. 423.
Chapter 58, Tennessee Public Acts, 1923, as amended by Chapter 67, Tennessee Public Acts, 1925, is said, by its caption, to impose a privilege tax “ on persons . . . and corporations engaged in or carrying on the business . . . of selling or storing or distributing gasoline . . .” within the state at the rate of 20 per gallon on the gasoline sold or stored, the tax “ to be used solely in the construction and maintenance of a highway system in the state.” •. But § 3 provides: “The tax imposed by this Act shall apply to persons, firms or corporations, dealers or distributors storing any of the products mentioned in this Act and distributing the same or allowing the same to be withdrawn from storage whether such withdrawal be for sale or other, use. / . .” Storage of the gasoline and withdrawal of it from storage within the state for use or sale,' aré, as the state Supreme Court has held, the events which, by the very terms of the statute, .call it into operation. Foster & Creighton Co. v. Graham, 154 Tenn. 412, 420; 285 S. W. 570; Quick Service Tire Co. v. Smith, 156 Tenn. 96, 102; 299 S. W. 807.
Appellant, an interstate rail carrier, purchases large quantities of gasoline outside the state of Tennessee and brings it into the state in tank cars, from which it is unloaded and placed in its own storage tanks. None of it is sold by appellant, but all is withdrawn and uséd by it as a source of motive power in interstate railway Operation in Tennessee, Kentucky, Alabama and Georgia. Storage of the gasoline is a preliminary step to such use in interstate commerce. The tax is assailed'both on'the ground that it is imposed on the gasoline while still .a subject of interstate eommérce in the course of transportation from points of origin to points outside the state of Tennesseé; and on the ground that it is. in effect a tax upon
The gasoline, upon being unloaded and stored, ceased to be a subject of transportation in interstate commerce and lost its immunity as such from state taxation. GeneraOil Co. v. Crain, 209 U. S. 211; Bacon v. Illinois, 227 U. S. 504; Susquehanna Coal Co. v. South Amboy, 228 U. S. 665, 669; Hart Refineries v. Harmon, 278 U. S. 499; Gregg Dyeing Co. v. Query, 286 U. S. 472. The fact that the oil was,, in the ordinary, course of appellant’s business, later withdrawn from storage for use, some within and some without the state, part of it thus becoming again the súbject of interstate transportation, did not affect the power of the state to tax it all before that transportation - commenced. Neither the appellant, the shippers, nor the carrier, at the time of the' shipment of the gasoline from points of origin, arranged a destination for any part .of the oil other than the ¡appellant’s storage tanks in Tennessee. Although in the usual course of business a variable and undefined part .of it, when segregated for that purpose, would again be transported across state boundaries, appellant was free to distribute the oil either within or without the state for use in its business or .for any other, purpose. As nothing in the transáction before the withdrawal from storage in Tennessee can- be said to have .given any ascertainable part of,the gasoline a destination to points beyond the state, the case is distinguishable from Carson Petroleum Co. v. Vial, 279 U. S. 95, and Texas & New Orleans. R. Co. v. Sabine Tram Co., 227 U. S. 111. The oil in storage was not a subject .of interstate commerce and so was a part of the common mass of goods within the state, subject to local taxation. General Oil Co. v. Crain, supra; Susquehanna Coal Co. v. South Amboy, supra; Bacon v. Illinois, supra; compare Atlantic Coast Line R. Co. v. Standard Oil Co., 275 U. S. 257.
But interstate rail carriers- are not wholly immune from other forms of non-discriminatory state taxation, even though the burden of the tax is thus indirectly or incidentally imposed upon the interstate -. commerce in which they are engaged. It cannot be doubted that, when the gasoline came to rest in storage, the state was as free to táx it, notwithstanding its prospective use as an instru-, ment of interstate commerce, as it was to tax appellant’s right of way, rolling stock or other instruments' of interstate commerce, which are subject to local property taxes. Cudahy Packing Co. v. Minnesota, 246 U. S. 450; U. S. Express Co. v. Minnesota, 223 U. S. 335; Western Union Telegraph Co. v. Gottlieb, 190 U. S. 412; Adams Express Co. v. Ohio, 165 U. S. 194, 220; see General American Tank Car Corp. v. Day, 270 U. S. 367; Interstate Busses Corp. v. Blodgett, 276 U. S. 245, compare St. Louis-San Francisco Ry. Co. v. Middlekamp, 256 U. S. 226, 231; St. Louis, Southwestern Ry. v. Arkansas, 235 U. S. 350; Kansas City, F. S. & M. Ry. Co. v. Botkin, 240 U. S. 227; Kansas City, M. & B. R. Co. v. Stiles, 242 U. S. 111; Southern Ry. Co. v. Watts, 260 U. S. 519. The power to
Appellant objects that the tax violates the Fourteenth Amendment in that it is levied as a charge for the use of the highways which appellant does not use. But the levy is a tax, not a toll or charge for use of the highways, see Carley & Hamilton v. Snook, 281 U. S. 66, and the constitutional power to levy taxes does not depend upon the enjoyment by the. taxpayer of any special benefit from the use of the funds raised by taxation. Carley & Hamilton v. Snook, supra; St. Louis & Southwestern Ry. Co. v. Nattin, 277 U. S. 157, 159. The allegations of the bill showing that a heavier burden of taxation is imposed upon railroads than upon common carriers by motor bus, examined in the light of the applicable statutes of the State, fall short of alleging a discrimination forbidden by either the commerce clause or the Fourteenth Amendment.
