In May 2009, the Supreme Court issued its decision in Ashcroft v. Iqbal, which explicitly extended the “plausibility standard,” first articulated in Bell Atlantic v. Twombly two years earlier, to all civil pleadings. That standard requires that pleadings, to satisfy Federal Rule of Civil Procedure 8(a), must state a plausible claim for relief. For many, these rulings represented a sea change in civil pleading standards. Where prior Supreme Court precedent had provided that a pleading should not be dismissed “unless it appears beyond doubt that the plaintiff can prove no set of facts in support of his claim,” the new standard requires that judges utilize their own “judicial experience and common sense” to determine whether claimants have set forth facts sufficient to “nudge[] their claims across the line from conceivable to plausible.”
