Consumers brought a putative class action against Bell Atlantic and other incumbent local exchange carriers, alleging that the companies violated § 1 of the Sherman Act. The complaint asserted that the defendants engaged in parallel conduct by declining to compete in one another's geographic markets and by making agreements with competitive local exchange carriers in ways that hindered competition. Plaintiffs claimed this conduct resulted from a conspiracy to restrain trade, but the complaint did not allege specific facts showing an actual agreement among the defendants. The district court dismissed the complaint, and the Second Circuit reversed.
Does a complaint alleging a Sherman Act § 1 conspiracy state a claim under Federal Rule of Civil Procedure 8(a) by alleging parallel conduct and a conclusory assertion of agreement, or must it plead enough factual matter to make the existence of an agreement plausible?
A complaint must contain enough factual matter to state a claim to relief that is plausible on its face. In a Sherman Act § 1 case, allegations of parallel conduct alone, coupled with a bare assertion of conspiracy, do not plausibly suggest an unlawful agreement.
No. The complaint failed to state a claim because it alleged only parallel conduct and conclusory assertions of conspiracy without enough factual content to plausibly suggest an agreement among the defendants.
The Court held that Rule 8 requires more than labels, conclusions, and a formulaic recitation of the elements of a cause of action. Parallel conduct is consistent with lawful, independent business behavior as well as with conspiracy, so allegations of such conduct, without more, stop short of plausibility. Because antitrust discovery is especially costly, the Court required factual allegations that raise a reasonable expectation that discovery will reveal evidence of illegal agreement. The Court also retired the broad reading of Conley v. Gibson's 'no set of facts' language as the governing pleading standard.
Justice Stevens, joined in part by Justice Ginsburg, argued that the complaint was sufficient under traditional notice-pleading principles and that the majority improperly heightened pleading standards without amending the Federal Rules.
Twombly reshaped federal pleading by establishing the modern 'plausibility' standard under Rule 8 and limiting purely conclusory pleadings, especially in complex antitrust litigation. It is closely linked with Ashcroft v. Iqbal, 556 U.S. 662 (2009), which generalized Twombly's plausibility approach beyond antitrust, and it rejected the expansive understanding of Conley v. Gibson, 355 U.S. 41 (1957). In antitrust doctrine, Twombly underscored that parallel conduct without 'plus factors' is insufficient to plead a § 1 agreement.
