Whether a court resolving a qualified-immunity defense must first determine whether the plaintiff has alleged the violation of a constitutional right, rather than proceed directly to the sufficiency of allegations of malice or to heightened pleading requirements.
Holding
Yes. A court must determine at the threshold whether the pleaded facts establish a constitutional violation at all before allowing discovery or evaluating whether the right was clearly established.
Reasoning
Qualified immunity is an immunity from suit, not merely a defense against ultimate liability. Under Harlow and Mitchell, its purpose is to protect officials from the burdens of litigation, including discovery, unless the plaintiff has alleged conduct that violates clearly established law.
Determining whether a claimed right was clearly established necessarily includes an antecedent legal question: whether the facts alleged amount to a violation of any constitutional right. Resolving that issue first allows courts to dismiss legally deficient suits without forcing an official asserting immunity to undertake expensive, time-consuming litigation.
The D.C. Circuit instead assumed that malicious conduct could establish a constitutional violation and focused on whether Siegert had pleaded malice with enough specificity. The Supreme Court held that this assumed issue had to be decided, because Siegert's claim failed before any inquiry into malice or the circuit's heightened pleading rule was necessary.
