owner of a General Motors car would blame GMC for the car’s improper performance caused by a defective part, especially if he did not know the origin of the trouble, but it is improbable that he would blame GMC because he was dispossessed or defrauded by an independent finance company. The finance restriction operates on the retail purchaser as well as on the dealer, and the competing discount companies are unable to finance General Motors cars. The parts restriction in the Pick case operated on the General Motors dealer only, and the competition of other parts manufacturers was not completely destroyed.
We hold that the coercive course of action indulged in, falls within reach of the Sherman láw.
E. Other Matters.
1. Single Trader. Counsel contend that the appellants are affiliated and non-competing units engaged in a single enterprise and hence they are in effect a single trader; that as a single trader they have a right to condition the sale of their product and to restrain their own product by selling it to whom they please; and that a combination of competing units is essential to conspiracy under the Sherman Act. Among other cases counsel cite United States v. Winslow, 227 U.S. 202, 33 S.Ct. 253, 57 L.Ed. 481; United States v. United Shoe Mach. Co., 247 U.S. 32, 38 S.Ct. 473, 62 L.Ed. 968; United States v. General Electric, 272 U.S. 476, 47 S.Ct. 192, 71 L.Ed. 362; Alexander Milburn Co. v. Union Carbide & Carbon Corp., 4 Cir., 15 F.2d 678, certiorari denied 273 U.S. 757, 47 S.Ct. 459, 71 L.Ed. 876; and Arthur v. Kraft-Phenix Cheese Corp., D.C., 26 F.Supp. 824.
This reasoning fails mainly because it assumes that the General Motors dealer is an agent of the manufacturer or, stated differently, because it considers the commerce from factory to retail public as the appellants’ commerce rather than as the dealers’ commerce. Clearly a vertical combination or combination of non-competitors may conspire to restrain unreasonably the interstate trade and commerce of third parties and thereby subject themselves to the prohibitions of the Sherman Act. Loewe v. Lawlor, supra, 208 U.S. 293-296, 28 S.Ct. 301, 52 L.Ed. 488, 13 Ann.Cas. 815; United States v. Patten, supra, 226 U.S. 541, 33 S.Ct. 141, 57 L.Ed. 333, 44 L.R.A.,N.S., 325; Patterson v. United States, 6 Cir., 222 F. 599, 618, 619.
Nor can the appellants enjoy the benefits of separate corporate identity and escape the consequences of an illegal combination in restraint of trade by insisting that they are in effect a single trader. The test of illegality under the Sherman Act is not so much the particular form of business organization effected, as it is the presence or absence of restraint of trade and commerce.- But even if the single trader doctrine were applicable, it would not help the appellants. See International Business Machines v. United States, supra; Radio Corporation v. Lord, supra. See also Dr. Miles Medical Co. v. Park & Sons Co., supra. Cf. Carbice Corp. v. American Patents, supra; dissent, Federal Trade Commission v. Gratz, supra, 253 U.S. 441, 40 S.Ct. 572, 64 L.Ed. 993.
This disposes of all the cases cited by counsel for the appellants except the KraftPhenix case which is distinguishable on the ground that only one dealer was affected and neither the interest of a third party nor the interest of the public was involved.
2. Exclusion of Evidence. It is argued that the Court committed prejudicial error when it excluded the testimony of dealer witnesses called by the defendants and cut off the calling of. additional dealer witnesses. The appellants offered to call all General Motors dealers, not called by the Government, to testify that they had not been discriminated against and coerced into using the facilities of GMAC.
The position of the appellants on this point is that they offered the excluded evidence to refute the Government’s evidence showing that there was a conspiracy. As stated by counsel for GMAC and GMAC (Ind.), “We did not offer our dealer testimony to refute the testimony of the Government’s dealer witnesses * we offered it to refute the inference which otherwise might have been drawn from the testimony of the Government’s dealer witnesses that the defendants had agreed upon the course of conduct represented by their treatment of those dealers.”
In our case restraints of trade were inherent in the purpose to control the dealers’ financing and this purpose, regardless of the intent or means, came within the prohibition of the Sherman Act. Moreover the Government was not obliged to adduce any evidence of acts and things done pursuant to the conspiracy, and proof of the conspiracy would have been sufficient
