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.

Opinion:
NATIONAL LABOR RELATIONS BOARD v. RELIANCE FUEL OIL CORP.
No. 88.
Argued December 3, 1962. —
Decided January 7, 1963.
Louis F. Claiborne argued the cause for petitioner. On the brief were Solicitor General Cox, Stuart Rothman, Dominick L. Manoli, Norton J. Come and Solomon I. Hirsh.
Samuel H. Borenkind argued the cause for respondent. With him on the brief was Frank J. Mercurio.
Per Curiam.
The Reliance Fuel Oil Corporation, respondent herein, was found by the National Labor Relations Board to have committed certain unfair labor practices in violation of the National Labor Relations Act, 49 Stat. 449, as amended, 29 U. S. C. § 151 et seq. Jurisdiction before the Board was predicated upon the fact that Reliance, a New York distributor of fuel oil whose operations were local, purchased within the State a “substantial amount” of fuel oil and related products from the Gulf Oil Corporation, a supplier concededly engaged in interstate commerce. Most of the products sold to Reliance by Gulf were delivered to Gulf from without the State of New York and prior to sale and delivery to Reliance were stored, without segregation as to customer, in Gulf’s tanks located within the State. During the fiscal year ending June 30, 1959, Reliance had gross sales in excess of $500,000 and, during the calendar year 1959, it purchased in excess of $650,000 worth of fuel oil and related products from Gulf.
The Board adopted its trial examiner’s findings that the operations of Reliance “affected” commerce within the meaning of the Act and that the unfair labor practices found tended “to lead to labor disputes burdening and obstructing commerce and the free flow of commerce ...” 129 N. L. R. B. 1166, 1171, 1182. The Court of Appeals reversed, 297 F. 2d 94, because, in its view, the record before the Board did not adequately demonstrate the existence of jurisdiction and remanded the case to the Board so that it might “take further evidence and make further findings on the manner in which a labor dispute at Reliance affects or tends to affect commerce.” The only issue before this Court is whether on the record before it the Board properly found that it had jurisdiction to enter an order against Reliance; the substantive findings as to the existence of the unfair labor practices are not here in dispute.
Under § 10 (a) of the Act, the Board is empowered “to prevent any person from engaging in any unfair labor practice (listed in section 8) affecting commerce.” Section 2 (6) defines “commerce” to mean “trade, traffic, commerce, transportation, or communication among the . . . States . . and § 2 (7) declares:
“The term 'affecting commerce’ means in commerce, or burdening or obstructing commerce or the free flow of commerce, or having led or tending to lead to a labor dispute burdening or obstructing commerce or the free flow of commerce.”
This Court has consistently declared that in passing the National Labor Relations Act, Congress intended to and did vest in the Board the fullest jurisdictional breadth constitutionally permissible under the Commerce Clause. See, e. g., Guss v. Utah Labor Board, 353 U. S. 1, 3; Polish Alliance v. Labor Board, 322 U. S. 643, 647-648; Labor Board v. Fainblatt, 306 U. S. 601, 607. Compare Weber v. Anheuser-Busch, Inc., 348 U. S. 468, 480. The Act establishes a framework within which the Board is to determine “whether proscribed practices would in particular situations adversely affect commerce when judged by the full reach of the constitutional power of Congress. Whether or no practices may be deemed by Congress to affect interstate commerce is not to be determined by confining judgment to the quantitative effect of the activities immediately before the Board. Appropriate for judgment is the fact that the immediate situation is representative of many others throughout the country, the total incidence of which if left unchecked may well become far-reaching in its harm to commerce.” Polish Alliance v. Labor Board, 322 U. S., at 648. See also Labor Board v. Fainblatt, 306 U. S., at 607-608.
That activities such as those of Reliance affect commerce and are within the constitutional reach of Congress is beyond doubt. See, e. g., Wickard v. Filburn, 317 U. S. 111. Through the National Labor Relations Act, “. . . Congress has explicitly regulated not merely transactions or goods in interstate commerce but activities which in isolation might be deemed to be merely local but in the interlacings of business across state lines adversely affect such commerce.” Polish Alliance v. Labor Board, 322 U. S., at 648. This being so, the jurisdictional test is met here: the Board properly found that by virtue of Reliance’s purchases from Gulf, Reliance’s operations and the related unfair labor practices “affected” commerce, within the meaning of the Act. The judgment of the Court of Appeals accordingly must be and is reversed.
Mr. Justice Black concurs in the result.
In 1969 Reliance purchased a few hundred dollars worth of truck parts in New Jersey, but the Board did not rely on such transactions to sustain its assertion of jurisdiction.
Since the Board apparently treated Reliance as a “retail” concern, this amount of gross sales met its self-imposed standard for exercise of jurisdiction. 129 N. L. R. B. 1166, 1170-1171.
