In 2007 the U.S. Supreme Court altered the applicable standard for a motion to dismiss. In Bell Atlantic v. Twombly, the Court held that the the 50-year-old test for whether a complaint states a cause of action was no longer valid. Whereas the old standard was whether the plaintiff could prove any set of
facts in support of his claim which would entitle him to relief, the new standard asks whether the complaint alleges
"enough facts to state a claim to relief that is plausible on its face."
In a decision issued today, Ashcroft v. Iqbal, the U.S. Supreme Court further examined the Twombly standard in the context of a terrorism suspect's civil rights claim against former AG John Ashcroft and former FBI Director Robert Mueller. The plaintiff's complaint alleged that Ashcroft and Mueller had adopted detention policies and applied them to the plaintiff and others like him because of their race, religion or national origin. The Court held that the allegations of the plaintiff's complaint were insufficient as a matter of law.
First, the Court rejected as conclusory the plaintiff's allegation that Ashcroft and Mueller knew of and maliciously agreed to subject him to harsh conditions of confinement solely on account of his race, religion, or national origin. "It is the conclusory nature of respondent's allegations, rather than their extravagantly fanciful nature, that disentitles them to the presumption of truth."
Second, the Court held that other allegations in the the plaintiff's complaint, while not conclusory, were implausible. The Court's plausibility analysis is the most interesting aspect of the opinion and warrants extended quotation:
The September 11 attacks were perpetrated by 19 Arab Muslim hijackers who counted themselves members in good standing of al Qaeda, an Islamic fundamentalist group. Al Qaeda was headed by another Arab Muslim—Osama bin Laden—and composed in large part of his Arab Muslim disciples. It should come as no surprise that a legitimate policy directing law enforcement to arrest and detain individuals because of their suspected link to the attacks would produce a disparate, incidental impact on Arab Muslims, even though the purpose of the policy was to target neither Arabs nor Muslims. On the facts respondent alleges the arrests Mueller oversaw were likely lawful and justified by his nondiscriminatory intent to detain aliens who were illegally present in the United States and who had potential connections to those who committed terrorist acts. As between that “obvious alternative explanation” for the arrests, Twombly, [550 U.S.] at 567, and the purposeful, invidious discrimination respondent asks us to infer, discrimination is not a plausible conclusion.
This case will receive lots of attention, of course, but for practitioners the Court's analysis indicates that defendants in civil lawsuits have broad leeway to attack the plaintiff's complaint on plausibility grounds. Notably, Justice Souter's dissenting opinion did not appear to disagree with the majority's plausibility analysis -- rather, he argued that the majority's analysis ignored several allegations in the complaint and the analysis therefore was improperly limited.
