Per Curiam.
The petitioner, Chicago Mercantile Exchange, was sued in two separate actions in the District Court. In one, the Phillips suit, it was alleged that the Exchange had forced sales of futures contracts in March 1970 fresh eggs at artificially depressed market prices and had thereby monopolized and restrained commerce in violation of §§ 1 and 2 of the Sherman Act, 26 Stat. 209, as amended, 15 U. S. C. §§ 1, 2, and had violated § 9 (b) of the Commodity Exchange Act (CEA), as amended, 82 Stat. 33, 7 U. S. C. § 13 (b), by manipulating prices of a commodity for future delivery on a contract market. The Exchange was also accused of violating § 5a of the CEA, 7 U. S. C. § 7a (8), for failure to enforce one of its own rules. In the second suit, the Deaktor case, the Exchange was charged with violating the CEA and its own rules as a designated contract market because it had failed to exercise due care to halt the manipulative conduct of certain of its members who allegedly had cornered the July 1970 market in frozen pork bellies futures contracts.
The Exchange defended both actions on the ground that it was faithfully discharging its statutory duty of self-regulation. It asserted that its challenged acts in the Phillips case were measures taken to prevent speculation in futures contracts and as such were not in violation of the CEA. Rather, they were authorized and required by the statute and hence cannot be considered within the reach of the antitrust laws. Likewise, in the Deaktor suit, the Exchange claimed that it had taken all proper and reasonable steps to perform its statutory responsibility to prevent manipulation.
The Exchange further urged that because the Commodity Exchange Commission had jurisdiction to determine whether the Exchange was violating the CEA or its own rules and to impose sanctions for any such offense, both suits should be stayed to permit the Commission to determine in the first instance whether or not the actions of the Exchange under scrutiny were in discharge of its proper duties under the CEA and its regulations. The District Court refused the stay, and the Court of Appeals affirmed. Deaktor v. L. D. Schreiber & Co., 479 F. 2d 529 (CA7 1973). Both courts were in error.
Ricci v. Chicago Mercantile Exchange, 409 U. S. 289 (1973), held that an antitrust action against the Exchange should have been stayed to afford the Commodity Exchange Commission an opportunity to determine if the challenged conduct of the Exchange was in compliance with the statute and with Exchange rules. Because administrative adjudication of alleged violations of the CEA and the rules lay at the heart of the task assigned the Commission by Congress, we recognized that the court, although retaining final authority to interpret the CEA and its relationship to the antitrust laws, should avail itself of the abilities of the Commission to unravel the intricate and technical facts of the commodity industry and to arrive at some judgnaent as to whether the Exchange had conducted itself in compliance with the law. An adjudication by the Commission that the actions of the Exchange were authorized or required by the CEA would not necessarily dispose of the question of immunity from antitrust liability. We nevertheless thought the considered view of the Commission would be of sufficient aid to the court that the action should not go forward without making reasonable efforts to invoke the jurisdiction of the Commission. Id., at 305-306. As we did in Ricci,
“we simply recognize that Congress has established a specialized agency that would determine either that a . . . rule of the Exchange has been violated or that it has been followed. Either judgment would require determination of facts and the interpretation and application of the Act and Exchange rules. And either determination will be of great help to the antitrust court in arriving at the essential accommodation between the antitrust and the regulatory regime . . . .” Id., at 307.
In our judgment, the Court of Appeals, as in Ricci, should have requested the District Court to stay the proceedings in the Phillips case to afford an opportunity to invoke the jurisdiction of the Commission. For very similar reasons, the Deaktor plaintiffs, who also alleged violations of the CEA and the rules of the Exchange, should be routed in the first instance to the agency whose administrative functions appear to encompass adjudication of the kind of substantive claims made against the Exchange in this case.
The petition for writ of certiorari is granted, the judgment of the Court of Appeals is reversed, and the case remanded for further proceedings consistent with this opinion.
So ordered.
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.
