kelloggStriking another blow to the plaintiffs’ bar, the Supreme Court toughened the standards to get into court on civil antitrust litigation claims. In a 7-2 opinion, the justices ruled that an allegation that two or more companies are acting in parallel isn’t enough for an antitrust lawsuit to proceed; plaintiffs must include some allegation indicating that the companies were actively working together. Here are stories from the WSJ and FT.

On the winning side, representing the Bells: Michael Kellogg (pictured) of D.C.’s Kellogg Huber; on the losing team, representing the plaintiffs: J. Douglas Richards, formerly of Milberg Weiss now at the Pomerantz law firm.

In Twombly, a group of consumers sued the Regional Bells alleging they conspired to jack up prices. The district court dismissed the case for lack of a sufficient pleading. But the Second Circuit reversed, ruling that the plaintiffs’ complaint was sufficient. When that happened, a host of industry groups airlines, credit cards, oil asked the court to take the case, fearing vexatious civil antitrust suits.

Law Blog colleague Jess Bravin writes that while the ruling doesn’t radically upend the rules for antitrust actions, it does mark the latest in a sequence of cases where the court has tightened the scope of the Sherman Act.

Writing for the majority, Justice Souter noted the high bar of antitrust litigation, writing that “the problem of discovery abuse” could cost innocent defendants huge sums. In dissent, Justice Stevens said the majority was driven not by settled law but a “transparent policy concern” to protect antitrust defendants from litigation costs.
