Whether the sufficiency of the second amended complaint under Twombly was a controlling question of law appropriate for interlocutory review under 28 U.S.C. § 1292(b).
Holding
Yes. In these unusual circumstances, the Twombly pleading issue was a controlling question of law warranting interlocutory appeal.
Reasoning
The question was controlling because a ruling that the complaint failed to state a claim would likely end the litigation. Without discovery, the plaintiffs were unlikely to obtain additional facts sufficient to support a further amended complaint.
Although the appeal concerned a particular set of pleaded facts, it did not ask the court to reweigh evidence or overturn factual findings. The defendants accepted the complaint's factual allegations as true and asked whether those allegations satisfied the legal pleading standard announced in Twombly.
The appeal also required clarification of Twombly itself, rather than a routine application of a settled rule. Twombly and Ashcroft v. Iqbal had left federal pleading doctrine in flux, and the Seventh Circuit had given little guidance on Twombly's application to antitrust claims.
Twombly seeks to prevent defendants from being forced into expensive and burdensome discovery when a complaint does not plausibly suggest a meritorious claim. In a complex antitrust case, an erroneous refusal to dismiss can immerse parties in a costly discovery process that cannot be undone after final judgment. The dual-certification requirement of § 1292(b) prevents such appeals from becoming routine.
