Task: sc_petitioner

What follows is an opinion from the Supreme Court of the United States. Your task is to identify the petitioner of the case. The petitioner is the party who petitioned the Supreme Court to review the case. This party is variously known as the petitioner or the appellant. Characterize the petitioner as the Court's opinion identifies them.

Identify the petitioner by the label given to the party in the opinion or judgment of the Court except where the Reports title a party as the "United States" or as a named state. Textual identification of parties is typically provided prior to Part I of the Court's opinion. The official syllabus, the summary that appears on the title page of the case, may be consulted as well. In describing the parties, the Court employs terminology that places them in the context of the specific lawsuit in which they are involved. For example, "employer" rather than "business" in a suit by an employee; as a "minority," "female," or "minority female" employee rather than "employee" in a suit alleging discrimination by an employer.

Also note that the Court's characterization of the parties applies whether the petitioner is actually single entity or whether many other persons or legal entities have associated themselves with the lawsuit. That is, the presence of the phrase, et al., following the name of a party does not preclude the Court from characterizing that party as though it were a single entity. Thus, identify a single petitioner, regardless of how many legal entities were actually involved. If a state (or one of its subdivisions) is a party, note only that a state is a party, not the state's name.

Justice Thomas
delivered the opinion of the Court.
From 1998 until 2002, petitioners Texaco Inc. and Shell Oil Co. collaborated in a joint venture, Equilon Enterprises, to refine and sell gasoline in the western United States under the original Texaco and Shell Oil brand names. Respondents, a class of Texaco and Shell Oil service station owners, allege that petitioners engaged in unlawful price fixing when Equilon set a single price for both Texaco and Shell Oil brand gasoline. We granted certiorari to determine whether it is per se illegal under § 1 of the Sherman Act, 15 U. S. C. § 1, for a lawful, economically integrated joint venture to set the prices at which the joint venture sells its products. We conclude that it is not, and accordingly we reverse the contrary judgment of the Court of Appeals.
I
Historically, Texaco and Shell Oil have competed with one another in the national and international oil and gasoline markets. Their business activities include refining crude oil into gasoline, as well as marketing gasoline to downstream purchasers, such as the service stations represented in respondents’ class action.
In 1998, Texaco and Shell Oil formed- a joint venture, Equilon, to consolidate their operations in the western United States, thereby ending competition between the two companies in the domestic refining and marketing of gasoline. Under the joint venture agreement, Texaco and Shell Oil agreed to pool their resources and share the risks of and profits from Equilon’s activities. Equilon’s board of directors would comprise representatives of Texaco and Shell Oil, and Equilon gasoline would be sold to downstream purchasers under the original Texaco and Shell Oil brand names. The formation of Equilon was approved by consent decree, subject to certain divestments and other modifications, by the Federal Trade Commission, see In re Shell Oil Co., 125 F. T. C. 769 (1998), as well as by the state attorneys general of California, Hawaii, Oregon, and Washington. Notably, the decrees imposed no restrictions on the pricing of Equilon gasoline.
After the joint venture began to operate, respondents brought suit in District Court, alleging that, by unifying gasoline prices under the two brands, petitioners had violated the per se rule against price fixing that this Court has long recognized under § 1 of the Sherman Act, ch. 647, 26 Stat. 209, as amended, 15 U. S. C. § 1. See, e. g., Catalano, Inc. v. Target Sales, Inc., 446 U. S. 643, 647 (1980) (per curiam). The District Court awarded summary judgment to Texaco and Shell Oil. It determined that the rule of reason, rather than a per se rule or the quick look doctrine, governs respondents’ claim, and that, by eschewing rule of reason analysis, respondents had failed to raise a triable issue of fact. The Ninth Circuit reversed, characterizing petitioners’ position as a request for an “exception to the per se prohibition on price-fixing,” and rejecting that request. Dagher v. Saudi Refining, Inc., 369 F. 3d 1108, 1116 (2004). We consolidated Texaco’s and Shell Oil’s separate petitions and granted certiorari to determine the extent to which the per se rule against price fixing applies to an important and increasingly popular form of business organization, the joint venture. 545 U. S. 1138 (2005).
II
Section 1 of the Sherman Act prohibits “[e]very contract, combination in the form of trust or otherwise, or conspiracy, in restraint of trade or commerce among the several States.” 15 U. S. C. § 1. This Court has not taken a literal approach to this language, however. See, e. g., State Oil Co. v. Khan, 522 U. S. 3, 10 (1997) (“[T]his Court has long recognized that Congress intended to outlaw only unreasonable restraints” (emphasis added)). Instead, this Court presumptively applies rule of reason analysis, under which antitrust plaintiffs must demonstrate that a particular contract or combination is in fact unreasonable and anticompetitive before it will be found unlawful. See, e. g., id., at 10-19. Per se liability is reserved for only those agreements that are “so plainly anti-competitive that no elaborate study of the industry is needed to establish their illegality.” National Soc. of Professional Engineers v. United States, 435 U. S. 679, 692 (1978). Accordingly, “we have expressed reluctance to adopt per se rules . . . ‘where the economic impact of certain practices is not immediately obvious.’ ” State Oil, supra, at 10 (quoting FTC v. Indiana Federation of Dentists, 476 U. S. 447, 458-459 (1986)).
Price-fixing agreements between two or more competitors, otherwise known as horizontal price-fixing agreements, fall into the category of arrangements that are per se unlawful. See, e. g., Catalano, supra, at 647. These cases do not present such an agreement, however, because Texaco and Shell Oil did not compete with one another in the relevant market — namely, the sale of gasoline to service stations in the western United States — but instead participated in that market jointly through their investments in Equilon. In other words, the pricing policy challenged here amounts to little more than price setting by a single entity — albeit within the context of a joint venture — and not a pricing agreement between competing entities with respect to their competing products. Throughout Equilon’s existence, Texaco and Shell Oil shared in the profits of Equilon’s activities in their role as investors, not competitors. When “persons who would otherwise be competitors pool their capital and share the risks of loss as well as the opportunities for profit.. . such joint ventures [are] regarded as a single firm competing with other sellers in the market.” Arizona v. Maricopa County Medical Soc., 457 U. S. 332, 356 (1982). As such, though Equilon’s pricing policy may be price fixing in a literal sense, it is not price fixing in the antitrust sense. See Broadcast Music, Inc. v. Columbia Broadcasting System, Inc., 441 U. S. 1, 9 (1979) (“When two partners set the price of their goods or services they are literally 'price fixing,’ but they are not per se in violation of the Sherman Act”).
This conclusion is confirmed by respondents’ apparent concession that there would be no per se liability had Equilon simply chosen to sell its gasoline under a single brand. See Tr. of Oral Arg. 34. We see no reason to treat Equilon differently just because it chose to sell gasoline under two distinct brands at a single price. As a single entity, a joint venture, like any other firm, must have the discretion to determine the prices of the products that it sells, including the discretion to sell a product under two different brands at a single, unified price. If Equilon’s price unification policy is anticompetitive, then respondents should have challenged it pursuant to the rule of reason. But it would be inconsistent with this Court’s antitrust precedents to condemn the internal pricing decisions of a legitimate joint venture as per se unlawful.
The court below reached the opposite conclusion by invoking the ancillary restraints doctrine. 369 F. 3d, at 1118-1124. That doctrine governs the validity of restrictions imposed by a legitimate business collaboration, such as a business association or joint venture, on nonventure activities. See, e. g., National Collegiate Athletic Assn. v. Board of Regents of Univ. of Okla., 468 U. S. 85, 113-115 (1984); Citizen Publishing Co. v. United States, 394 U. S. 131, 135-136 (1969). Under the doctrine, courts must determine whether the nonventure restriction is a naked restraint on trade, and thus invalid, or one that is ancillary to the legitimate and competitive purposes of the business association, and thus valid. We agree with petitioners that the ancillary restraints doctrine has no application here, where the business practice being challenged involves the core activity of the joint venture itself — namely, the pricing of the very goods produced and sold by Equilon. And even if we were to invoke the doctrine in these cases, Equilon’s pricing policy is clearly ancillary to the sale of its own products. Judge Fernandez, dissenting from the ruling of the court below, put it well:
“In this case, nothing more radical is afoot than the fact that an entity, which now owns all of the production, transportation, research, storage, sales and distribution facilities for engaging in the gasoline business, also prices its own products. It decided to price them the same, as any other entity could. What could be more integral to the running of a business than setting a price for its goods and services?” 369 F. 3d, at 1127.
See also Broadcast Music, supra, at 23 (“Joint ventures and other cooperative arrangements are ... not usually unlawful, at least not as price-fixing schemes, where the agreement on price is necessary to market the product at all”).
* * *
Because the pricing decisions of a legitimate joint venture do not fall within the narrow category of activity that is per se unlawful under § 1 of the Sherman Act, respondents’ antitrust claim cannot prevail. Accordingly, the judgment of the Court of Appeals is reversed.
It is so ordered.
Justice Alito took no part in the consideration or decision of these cases.
We presume for purposes of these cases that Equilon is a lawful joint venture. Its formation has been approved by federal and state regulators, and there is no contention here that it is a sham. As the court below noted: “There is a voluminous record documenting the economic justifications for creating the joint ventures. [T]he defendants concluded that numerous synergies and cost efficiencies would result” by creating Equilon as well as a parallel venture, Motiva Enterprises, in the eastern United States, and “that nationwide there would be up to $800 million in cost savings annually.” 369 F. 3d 1108, 1111 (CA9 2004). Had respondents challenged Equilon itself, they would have been required to show that its creation was anticompetitive under the rule of reason. See Copperweld Corp. v. Independence Tube Corp., 467 U. S. 752, 768 (1984).
Respondents have not put forth a rule of reason claim. 369 F. 3d, at 1113. Accordingly, we need not address petitioners’ alternative argument that § 1 of the Sherman Act is inapplicable to joint ventures.
Respondents alternatively contend that petitioners should be held liable under the quick look doctrine. To be sure, we have applied the quick look doctrine to business activities that are so plainly anticompetitive that courts need undertake only a cursory examination before imposing antitrust liability. See California Dental Assn. v. FTC, 526 U. S. 756, 770 (1999). But for the same reasons that per se liability is unwarranted here, we conclude that petitioners cannot be held liable under the quick look doctrine.
