Opinion of the Court by
announced by Mr. Justice Black.
These are companion cases to Rice v. Santa Fe Elevator Corp. and Illinois Commerce Commission v. Santa Fe Elevator Corp., ante, p. 218, decided this day. Respondent in these cases, the Chicago Board of Trade, was joined as a defendant in the proceeding brought by Rice before the Illinois Commerce Commission. As we have noted in our opinion in the companion cases, the Rice complaint charged the defendant ware-housemen with maintaining excessive, unreasonable and discriminatory rates and practices, with operating inadequate and unsafe facilities and services, and with failure to comply with other requirements of Illinois law. The Board of Trade, organized under a special Act of the Illinois legislature, operates a commercial grain exchange and has adopted rules and regulations governing transactions on the exchange. The complaint of Rice charges (1) that the rules and regulations of the Board are unreasonable and unsatisfactory in that, among other things,
The Board moved to dismiss the proceeding before the Commission on the ground that the Commodity Exchange Act, 49 Stat. 1491 , as amended, 7 U. S. C. § 1 et seq., and the regulations thereunder superseded the provisions of Illinois law which Rice sought to invoke. That motion was denied. Thereupon, these suits were instituted in the District Court to enjoin the proceedings before the Illinois Commerce Commission. The District Court dismissed the complaints. The Circuit Court of Appeals reversed. 156 F. 2d 33 . The cases are here on certiorari.
The Chicago Board of Trade is “the greatest grain market in the world.” Board of Trade v. Olsen, 262 U. S.
1 That section provides: “No rule or regulation of any board of trade or grain exchange which relates to the warehousing of grain in any public grain warehouse, or which relates to the custody of grain in any private warehouse, or the use or negotiation of custodian’s receipts for such grain, shall be or become operative until such rule or regulation is approved by the Illinois Commerce Commission, and the Illinois Commerce Commission may adopt and promulgate reasonable rules and regulations consistent with the provisions of this Act for the purpose of making this Act effective.”
The Commodity Exchange Act provides comprehensive regulation of trading in futures on commodity exchanges which are designated as “contract markets” by the Secretary of Agriculture. The Secretary is authorized to designate any board of trade as a contract market on its compliance with prescribed terms and conditions. § 5. The Chicago Board of Trade has been so designated. The Act contemplates that each contract market will adopt rules governing transactions in futures contracts. Approval of a board of trade as a contract market may be made only when “the governing board thereof provides for the prevention of manipulation of prices and the cornering of any commodity by the dealers or operators upon such board.” § 5 (d). The Act contains provisions which prohibit certain types of trading practices (see for example §§ 4b, 4c, 4h) and other provisions (as for example those dealing with excessive speculation, see § 4a) which limit or control buying and selling on contract markets. But we are not particularly concerned with those phases of the federal regulatory scheme. So far as the problem of supersedure is concerned, this Act is unlike the one considered in the companion cases, as we shall see. Moreover, the subject matter of the complaint filed by Rice with the Illinois Commission against the Board of Trade relates only to the warehousing of grain. On that matter the Act has only two specific provisions.
It provides in the first place that receipts issued under the United States Warehouse Act, 39 Stat. 486 , as amended, 7 U. S. C. § 241 et seq., shall be accepted with
Enough of the Act has been summarized to show that it imposes on contract markets, under the supervision of the Secretary, (1) duties of preventing or controlling certain trading practices and of supervising transactions in futures contracts, and (2) some responsibility for standardizing deliverable warehouse receipts and assuring their integrity. The failure or refusal of a board of trade to comply with the provisions of the Act or any of the rules and regulations of the Secretary is cause for suspension or revocation of the authority of the board to act as a contract market. § 5b. And see § 6 (a). Criminal penalties are provided for certain violations of the Act, or of rules or regulations of the Secretary, by a board of trade or any of its directors, officers, agents or employees. § § 6b, 9. The Secretary has the power to “make such investigations as he may deem necessary to ascertain the facts regarding the operations of boards of trade . . . .” § 8.
The Secretary has promulgated numerous rules and regulations covering a variety of subjects pertaining to contract markets and their activities.[2] The following are relevant here, since they relate to the warehousing of grain: (1) a requirement that each contract market file information concerning warehouses in which or out of which commodities are deliverable in satisfaction of futures contracts made on the contract market, § 1.43; and (2) a provision that each contract market shall require operators of warehouses whose receipts are deliverable in satisfaction of futures contracts made on or subject to the rules of the contract market (a) to keep specified records, (b) to furnish information concerning stocks of commodities in warehouses, (c) to permit visitation of the premises and inspection of the books and records by duly authorized representatives of the Federal Government. § 1.44.
In pursuance of the latter regulation of the Secretary, the Board of Trade enacted the rules and regulations which Rice challenged in the proceedings before the Illinois Commission. One rule provides that deliveries shall be made by delivery of warehouse receipts issued by warehouses which have been declared “regular” by the Board. Rule 281. The Board’s regulations relating to warehousing of grain set forth the procedure and standards by which warehouses may be made “regular.”[3]
2 The rules and regulations are to be found in 17 C. F. R., Part 1.
3 These regulations provide, inter alia, that the warehouses must be “conveniently approachable by vessels of ordinary draft,” have “customary shipping facilities,” and charge rates not exceeding a specified maximum (Reg. 1620); must file a bond satisfactory to the Board (Reg. 1621); must have proprietors or managers in “unquestioned good financial standing and credit” (Reg. 1624); must be “connected by railroad tracks with one or more of the eastern railway lines” (Reg. 1625); and must be “provided with modern improve *253 ments and appliances for the convenient and expeditious receiving, handling, and shipping of grain in bulk.” (Reg. 1626.) Any “regular” warehouse may be declared “irregular” by the Board at any time for violation of the laws of Illinois or the rules and regulations of the Board (Reg. 1623), or because of any important change in the conditions of any warehouse or disregard or evasion of the requirements governing regular warehouses (Reg. 1629).
Congress treated the rules and regulations of the Board of Trade differently from those of the Secretary. It did not undertake to put behind them civil or criminal sanctions.[4] It merely furnished standards (or authorized the
4 We therefore have no attempt here to endow private groups with law-making functions. Cf. Schechter Corp. v. United States, 295 U. S. 495 ; United States v. Socony-Vacuum Oil Co., 310 U. S. 150 , 225-227; Parker v. Brown, 317 U. S. 341 , 350-352.
Hence it seems to us that no action of the Illinois Commission within the zone where the Board has freedom to act would contravene the federal scheme of regulation.[6] It would be quite a different matter if the Illinois Commission adopted rules for the Board which either violated
5 In the present proceeding the question of the validity of the existing rules and regulations of the Board of Trade under the Commodity Exchange Act is not in issue, and we intimate no opinion upon it.
6 It is suggested that the regulations of the Board of Trade or those which the Illinois Commerce Commission may impose on it are automatically invalid insofar as they relate to warehouses. For in Rice v. Santa Fe Elevator Corp., supra, we have held that the United States Warehouse Act excludes all state regulation, no matter how complementary, of those subjects touched by the federal regulatory scheme. But the situation here is quite different. In the first place, we are dealing with a measure of regulation over warehouse receipts not federal warehousemen; and the regulations which the Board of Trade is authorized to formulate do not carry civil or criminal sanctions. In the second place, Congress by granting the Board of Trade freedom to regulate within this narrow field has by that very act negatived any inference that the Federal Government has preempted it by requirements of its own.
There is other intrinsic evidence that Congress did not preclude state regulation which supplements or bolsters the federal scheme. Sections 4b and 4c of the Act make unlawful a variety of fraudulent and deceptive practices on contract markets. And § 4c provides that “nothing in this section or section 4b shall be construed to impair any State law applicable to any transaction enumerated or described in such sections.” These fraudulent practices, or many of them, have long been the occasion for the exercise by the States of their historic police powers. Federal regulation in those fields would therefore almost certainly conflict with state laws. Thus the provision in § 4c serves the function of preventing supersedure and preserving state control in two areas where state and federal law overlap. Where Congress used such care to preserve specific state authority, even when it duplicated federal regulation, it is a fair inference not only that supersedure was to take its natural course where rights not saved to the States were involved, First Iowa HydroElectric Coop. v. Federal Power Commission, 328 U. S. 152 , 175, but also that non-conflicting state authority was left undisturbed. Moreover the provision in § 12 of the Act that the Secretary “may cooperate with any department or agency of the Government, any State ... or political subdivision thereof” supports the inference that Congress did not design a regulatory system which excluded state regulation not in conflict with the federal requirements. See Townsend v. Yeomans, 301 U. S. 441 , 454; Union Brokerage Co. v. Jensen, 322 U. S. 202 , 209.
Respondents’ claim of supersedure is, therefore, premature. Until it is known what rules the Illinois Commission will approve or adopt, it cannot be known whether
