What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.

Mr. Justice Douglas
delivered the opinion of the Court.
El Paso Natural Gas Co. is an interstate natural gas pipeline company that delivers gas at the Arizona-California border to three California distribution companies. The present controversy concerns gas to be purchased by it in Texas from Lo-Vaca Gathering Co. and Houston Pipe Line Co. Under Lo-Vaca’& contract gas produced in Texas is to be delivered to a subsidiary of El Paso’S at a Texas point for delivery, into its pipeline. The contract contains the following two clauses:
“All of the gas to be purchased by El Paso from Gatherer [Lo-Vaca] under this agreement shall be used by El Paso solely as fuel in El Paso’s compressors, treating plants, boilers, camps and other facilities locátéd outside of the State of Texas. It is understood, however, that said gas will be commingled with other gas being transported in El Paso’s pipe fine system.”
“It is the intent and understanding of the parties hereto that the sale of natural gas hereof is not subject to the jurisdiction of the Federal Power Commission because this sale is not for resale.”
This “restricted use” agreement provides for a Separate metering of the contract volumes prior to their delivery info El Paso’s system. El Paso will meter the. gas used for fuel purposes in its New Mexico and Arizona facilities to make certain this amount invariably exceeds the volumes of gas taken from Lo-Vaca under this agreement.
El Paso and Houston made a similar contract containing a similar “restricted use” provision by which El Paso covenants that this Houston gas will be consumed by El Paso solely as fuel in its Texas operations or in another Texas plant. This contract, like the other one, also provides for metering the volume of gas delivered in Texas; and it includes a covenant by El Paso that the Texas uses will &t all times exceed the amounts supplied by Houston.
In spite of these "restricted use” covenants it is conceded that the gas sold by Lo-Vaca and Houston to El Paso will flow in a commingled stream with gas from other sources and that at least a portion of the gas will in fact be resold out of Texas.
The Federal Power Commission asserted jurisdiction over these sales as sales in interstate commerce “for resale,” as that term is used in § 1 (b) of the Natural Gas Act, 52 Stat. 821, 15 U. S. C. § 717 (1958 ed.). 26 F. P. C. 606, rehearing denied, id., at 840. The Court of
Appeals reversed, one judge dissenting. 323 F. 2d 190. The case is here on a writ of certiorari. 377 U. S. 951.
We said in Connecticut Co. v. Federal Power Comm’n, 324 U. S. 515, 529, “Federal jurisdiction was to follow the flow of electric energy, an engineering and scientific, rather than a legalistic or governmental, test.” And that is the test we have followed under both the Federal Power Act and the Natural Gas Act, except as Congress itself has substituted a so-called legal Standard for the technological one. Id., at 530-531. In Interstate Natural Gas Co. v. Federal Power Comm’n, 331 U. S. 682, 687, we considered the anatomy of the pipeline system to discover the channel of the constant flow; again in Federal Power Comm’n v. East Ohio Gas Co., 338 U. S. 464, 467; and most recently in Federal Power Comm’n v. Southern Cal. Edison Co., 376 U. S. 205, 209, n. 5. The result of our decisions is to make the sale of gas which crosses a state line at any stage of its movement from wellhead to ultimate consumption “in interstate commerce” within the meaning of the Act.
Attempts have been made by one convention or another to convert a local transaction into one of interstate commerce (Sprout v. South Bend, 277 U. S. 163; Superior Oil Co. v. Mississippi, 280 U. S. 390) or to make a segment of interstate commerce appear to be only intrastate (Baltimore & Ohio R. Co. v. Settle, 260 U. S. 166). But those attempts have failed. Similarly, we conclude that when it comes to the question what gas is for “resale” the present contracts should not be able to change the jurisdictional result.
The fact that a substantial part of the gas will be resold, in our view, invokes federal jurisdiction at the outset over the entire transaction. Were suppliers of gas and pipeline companies free to allocate by contract gas from a particular source to a particular use, havoc would be raised with the federal regulatory scheme, as it was construed arid applied in Phillips Petroleum Co. v. Wisconsin, 347 U. S. 672. A pipeline would then be able to discriminate in favor of its “nonjurisdictional” customers. Moreover, a pipeline compariy by a contract clause could immunize a particular supplier from the reach of federal regulation as defined by Phillips Petroleum Co. v. Wisconsin, supra. There would be created in those and in other ways an “attractive gap” in the federal regulatory scheme (Federal Power Comm’n v. Transcontinental Gas Pipe Line Corp., 365 U. S. 1, 28) which the producing States might have little incentive to close, since the gap would often involve either lower costs to intrastate customers or else merely higher pipeline costs which ultimately would be reflected in rates paid by consumers in other States. Whether cases could be conjured up where in spite of original commingling there might be a separate so-called nonjurisdictional transaction of a precise amount of gas not-for-resale within the meaning of the Act is a question we need not reach.
Finally it is said that the Commission should draw the appropriate lines between “jurisdictional'’ and “nonjuris-dictional” sales through the use of its rule-making power. But we cannot say. that the ádjüdicatory process is not an appropriate method, for drawing the line case-by-case (United States v. Public Utilities Comm’n, 345 U. S. 295) as in a,''host of other administrative determinations. The Commission has acted responsibly in this situation and its decision must be upheld.
Reversed.
Mr. Justice White took no part in the consideration or decision of these cases.
Section 1 (b) of the Act provides:
“The provisions of this Act shall apply to the transportation of natural gas in interstate commerce, to the sale in interstate commerce of natural gas for resale for ultimate public consumption for domestic, commercial, industrial, or any other use, and to natural-gas companies engaged in such transportation or sale, but shall not apply to any other transportation or sale of natural gas or to the local distribution of natural gas or to the facilities used for such distribution or to the production or gathering of natural gas.”
Section 2 (7) of the Act reads as follows:
“When used in this Act, unless the context otherwise requires—
“(7) ‘Interstate commerce’ means commerce between any point in a State and any point outside thereof, or between points within the same State but through any place outside thereof, but only insofar as such commerce takes place within the United States.”
The Commission’s Report, .Statistics of Natural Gas Companies— 1962, shows that the 40 major natural gas pipeline companies consumed more than $85,000,000 worth of gas in operating their facilities (principally compressor stations), p. xviii. This represents almost 4% of the total gas-purcháse-costs of those companies. The Commission therefore points out in its brief that pipeline companies, merely by using “restricted use” controls, could without changing their actual operations create a substantial unregulated market for the benefit of particular producers. .
Our reference in Federal Power Comm’n v. Transcontinental Gas Pipe Line Corp., 365 U. S. 1, 4, to “direct” sales of gas to industrial users as nonjurisdictional sales is not dispositive of the present issue. For the Commission had refused a certificate for transportation of the gas because from the standpoint of conservation it considered the end use as boiler fuel to be inferior. Whether the Commissi on had authority to assert jurisdiction over .the so-called “direct” sale because it was “for resale” as a result of its commingling with other gas was not in issue.
Cf. United States v. Public Utilities Comm’n, 345 U. S. 295, 317-318; City of Hastings v. Federal Power Comm’n, 221 F. 2d 31.
