Appellants (Cargo Gasoline Company, Cargo Service Stations, Inc., Eastern Oil Company, T. D. McRae, Inc., and United Petroleum, Inc.), eight other corporate entities, and four individuals were charged in a one count indictment with engaging in a continuing conspiracy to fix prices for the retail sale of gasoline in Florida in unreasonable restraint of commerce, in violation of the Sherman Act, 15 U.S.C.A. § 1. Various other persons or entities, including the Florida Independent Gasoline Marketers Association [FIGMA], were named as unindicted co-conspirators. Eight corporate defendants and one individual defendant entered pleas of nolo contendere, which the district court accepted. The eight corporate defendants were sentenced to pay fines ranging from $20,000 to $300,000; the individual defendant was fined $20,000 and sentenced to imprisonment of one year, with eleven months suspended. The other defendants proceeded to trial.
The jury returned verdicts of not guilty with respect to the individual defendants and guilty with respect to the corporate defendants. The corporate defendants, who were fined from $70,000 to $250,000 for a total of $645,000, appeal.
A brief summary of the voluminous evidence presented at trial will suffice for purposes of this opinion. The persons and companies charged in the indictment [hereinafter referred to as conspirators] were independent retail marketers of gasoline in Florida during the period covered by the indictment. Unlike major brand marketers such as Exxon or Texaco, the independent retail marketers did not develop a national image through advertising and did not offer services such as repairs and credit card purchases. Instead, the independents attracted *679 customers on the basis of a lower price, and thus their profits depended on a high volume of trade. The independents were fiercely competitive: a price difference as small as one cent per gallon between two stations in the same general location could result in such a loss of trade from the higher priced station to the lower that the higher priced station might soon cease doing business if its price were not adjusted to meet the competition. This extreme price sensitivity often resulted in “gas wars”; during some gas wars all retailers sold gasoline below cost.
The Government presented twenty-seven witnesses at trial, nineteen of whom were current or former employees of the indicted companies. Other witnesses included executives of the indicted companies’ competitors and wholesale suppliers, an individual station operator, and a FIGMA employee. The testimony of the witnesses and documentary evidence, which will be described more fully below, attested to an agreement and a continuous course of action whereby executives of conspirator corporations and FIGMA’s director contacted each other to assure coordinated joint price increases, to maintain high prices by challenging “price-cutters,” and to stem local price disputes that could lead to gas wars. Appellants, on the other hand, testified that they only exchanged innocent price information and that their activity was necessary to conduct business in the extremely price-sensitive gasoline market.
Five grounds of error are advanced on appeal. First, appellants argue that the evidence was not sufficient to establish that the conspiracy occurred in or affected interstate commerce and thus the conspiracy, if it existed, did not fall within the scope of the Sherman Act. Second, appellants urge that the jury verdict is not supported by sufficient evidence. Third, appellants contend that the district court erred in instructing the jury on the jurisdictional and substantive elements of the offense. Fourth, appellants maintain that the district court erroneously refused them permission to interview the jurors concerning alleged juror misconduct. Last, appellants assert that they are entitled to a judgment notwithstanding the verdict since every person who could have acted as their agent has been acquitted of criminal wrongdoing. We find no merit in these contentions and accordingly affirm the convictions.
We turn first to appellants’ contention that the evidence was insufficient to establish that the conspiracy occurred in or affected interstate commerce and thus did not fall within the purview of the Sherman Act. Section 1 of the Sherman Act prohibits conspiracies “in restraint of trade or commerce among the several states.” This language has been construed to prohibit restraints that occur in the flow of interstate commerce or that substantially affect interstate commerce. Burke
v. Ford,
The Sherman Act embodies a Congressional policy to exercise “the utmost extent of [Congress’] Constitutional power in restraining trust and monopoly agreements . . . . ”
Gulf Oil Corp. v. Copp Paving Co.,
The Government presented evidence that one of the conspirators owned outlets at six Days Inn Motels, which were located near interstate highways and which had a substantial number of interstate customers. Furthermore, the evidence showed that other conspirators had stations adjoining interstate highways or near the state boundaries. Finally, one of the conspirators, through its office in St. Louis, issued credit cards to its St. Louis customers and then honored these credit cards at its Florida stations. We think that this evidence, 1 viewed in light of modern transportation patterns, amply supports a finding that a conspiracy to control the prices of gasoline at these stations would substantially affect interstate commerce. 2
Appellants next urge that the jury verdict is not supported by sufficient evidence. But the verdict of the jury must be sustained “if there is substantial evidence, taking the view most favorable to the Government, to support it.”
Glasser v. United States,
Appellants seek to characterize the evidence summarized above as evidence of a mere exchange of pricing information. Such an exchange of pricing data, appellants reason, “does not invariably have anti-competitive effects; indeed, such practices can in certain circumstances increase economic efficiency and render markets more, rather than less, competitive.”
United States v. United States Gypsum Co.,
Appellants advance as their third contention the argument that the district court erred in instructing the jury on the jurisdictional and substantive elements of the offense. The argument relating to the instruction on jurisdiction clearly has no merit. The instruction contained a correct statement of the law.
See United States v. Cadillac Overall Supply Co., supra,
We find equally unpersuasive the argument relating to the instruction on the substantive element of the offense. The district court charged the jury:
To establish the required intent the Government must prove beyond a reasonable doubt that the defendants knowingly did something which the law forbids. In this case, that means that the Government must prove beyond a reasonable doubt that the defendants knowingly formed, joined or participated in a combination or conspiracy to fix, raise, maintain or stabilize retail prices of gasoline in Florida. Since, as I have already instructed you, a combination or conspiracy to fix prices is unreasonable and illegal as a matter of law, the Government does not have to prove that the defendants specifically intended to unreasonably restrain trade or that such conduct is an unreasonable restraint of trade ....
Relying on
United States v. United States Gypsum Co., supra,
Defendants in Gypsum were charged with conspiracy to raise, fix, maintain and stabilize the price of their products. In Gypsum the Government focused on inter-seller price verification, charging that price exchanges among defendants were part of an agreement that had the effect of stabilizing prices and policing agreed-upon price increases. Defendants defended on the *682 ground that the exchanges were for purposes of complying with the Robinson-Pat-man Act and preventing customer fraud. Thus, defendants reasoned, their purpose in engaging in the price verifications was a threshold factual question. The district court adopted this reasoning in part and charged the jury that if the exchanges of price information were undertaken in a good faith effort to comply with the Robinson-Patman Act verification alone would be insufficient to establish illegal price fixing. However, the district court in Gypsum deemed the purpose of defendants’ actions irrelevant if the effect of the verification was to fix, maintain, or stabilize prices. Accordingly, the jury was charged:
The law presumes that a person intends the necessary and natural consequences of his acts. Therefore, if the effect of the exchanges of pricing information was to raise, fix, maintain, and stabilize prices, then the parties to them are presumed, as a matter of law, to have intended that result.
United States v. United States Gypsum Co., supra,
The Court of Appeals for the Third Circuit reversed the convictions and the Supreme Court affirmed that result. The Supreme Court concluded that a defendant’s intent is an “element of a criminal antitrust offense which must be established by evidence and inferences drawn therefrom ----”
Id.
at 435,
The situation in Gypsum is easily distinguishable from that of the instant case. Even though the Government in Gypsum charged that the effect of defendants’ conduct was to fix prices, the Government did not present direct evidence of price fixing. Rather the Government focused on the exchange among competitors of price information as providing circumstantial evidence of price fixing. Unlike price fixing, the mere exchange of price information has been held not to be a per se violation
4
of the Sherman Act.
E. g., United States v. Citizens & Southern National Bank,
Unlike the situation in
Gypsum,
in the present case the district court did not require the jury to infer the requisite intent from a finding that the exchange of price information had an impact on prices.
5
Rather, the district court equated the intent to fix prices with the requisite intent to unreasonably restrain commerce. Price fixing, as opposed to price verification, is an activity with inevitable anticompetitive effects;
6
because of its inevitable effects the Supreme Court designated it illegal
per se. United States
v.
Socony-Vacuum Oil Co., supra,
Appellants alternatively urge that the jury instruction denied them due process of law because it allowed the jury to convict them absent a showing that all elements of the crime were present.
7
In spe
*684
cific, appellants argue that intent to restrain competition is an element of a violation of the Sherman Act and that thé instruction of the district court improperly allowed the jury to convict absent a finding of intent. We agree that intent is an element of a criminal antitrust offense.
United States
v.
United States Gypsum Co., supra,
Appellants’ next argument concerns potential juror misconduct. On the second day of deliberations the jury announced itself hopelessly deadlocked. The district court twice gave the jury a modified
Allen
charge,
see Allen v. United States,
Appellants insist that they should have been allowed to interview the jurors to determine if the members of the jury engaged in a compromise. Arguments such as this have been repeatedly rejected by this Court on the ground that “[ijnquiries that seek to probe the mental process of jurors .. . are impermissible.”
Llewellyn v. Stynchcombe,
Finally, appellants assert that they are entitled to a judgment notwithstanding
*685
the verdict since every person who could have acted as their agent has been acquitted of criminal wrongdoing. In support of their argument, appellants cite
C & H Cattle Co. v. Commonwealth,
We find no error in the record and accordingly AFFIRM.
Notes
. In our automobile-oriented society the vast majority of persons depend upon gasoline-powered vehicles not only to travel but also to engage in their livelihoods, which, in our complex and interrelated economic system, usually affect interstate commerce. Hence, a persuasive argument can be made that an agreement restraining the trade of gasoline must necessarily affect interstate commerce. However, because the Government presented evidence showing a nexus between the interstate travel of persons and the conspirator gasoline stations, we do not address the merits of the above argument.
. Because we find that the evidence supports the finding that the conspiracy substantially affected interstate commerce, we have no need to address the issue whether the restraint occurred in the flow of commerce.
. Part of appellants’ confusion is due to their consistent characterization of their conduct as being an exchange of prices. As we explained earlier, at trial the Government presented evidence of price fixing and the jury chose to credit this evidence.
. Certain types of restraints, such as price fixing or some types of market division, are in and of themselves unreasonable restraints on trade; these restraints are referred to as per se violations of the antitrust statutes. See, e.
g., United States v. Topco Associates,
[T]here are certain agreements or practices which because of their pernicious effect on competition and lack of any redeeming virtue are conclusively presumed to be unreasonable and therefore illegal without elaborate inquiry as to the precise harm they have caused or the business excuse for their use.
This principle of
per se
unreasonableness not only makes the type of restraints which are proscribed by the Sherman Act more certain to the benefit of everyone concerned, but it also avoids the necessity for an incredibly complicated and prolonged economic investigation into the entire history of the industry involved, as well as related industries, in an effort to determine at large whether a particular restraint has been unreasonable — an inquiry so often wholly fruitless when undertaken. Among the practices which the courts have heretofore deemed to be unlawful in and of themselves are price fixing,
United States v. Socony-Vacuum Oil Co.,
. The instant case differs from
Gypsum
in an additional way. In the instant case, direct evidence of price fixing was presented; in
Gypsum
the Government relied on circumstantial evidence, in the form of price verifications, to prove price fixing. This distinction, however, does not affect the outcome of this case. Convictions in this case would be valid even if they rested solely on circumstantial evidence
so long as
the jury was required, as here, to find that defendants knowingly engaged in a conspiracy to fix prices. If the jury finds the requisite intent, it matters not that the finding rests on circumstantial evidence. See, e.
g., Holland v. United States,
. “[Rjesort to the per se rule is justified only when the presence of exclusionary or coercive conduct warrants the view that the arrangement in question is a ‘naked restraint of trade.’ ”
E. A. McQuade Tours, Inc. v. Consolidated Air Tour Manual Comm.,
. Appellants liken the instant case to cases concerning presumptions.
See Sandstrom v. Montana,
Neither a conclusive nor a permissive presumption is at issue here. As explained above, in this case we equate a finding of intent to fix prices with an intent to unreasonably restrain trade. Nevertheless, appellants phrase the issue in terms of presumptions, arguing that the district court mandated a presumption of intent to restrain trade from a finding that appellants fixed prices. Phrasing the issue in terms of a mandatory presumption does not alter our re-suit, however, for the Supreme Court has indicated that mandatory presumptions are not always impermissible. To base a conviction on a mandatory presumption, “the fact proved [must be] sufficient to support the inference of guilt beyond a reasonable doubt.”
