Incident Summary & Facts
In 2002, Brian Bartholomew, who had become an informant for the Central Utah Narcotics Task Force after being charged with possessing methamphetamine, told Officer Jeffrey Whatcott that Afton Callahan had arranged to sell him methamphetamine. That evening Bartholomew went inside Callahan’s residence, confirmed the drugs were available, and left, saying he needed money. Around 9 p.m., task force officers searched him, gave him a marked $100 bill and a concealed electronic transmitter, and agreed on a signal for when he had completed the purchase. Callahan’s daughter let Bartholomew into the trailer home, and Callahan sold him a gram of methamphetamine from a large bag kept in the freezer. Bartholomew gave the arrest signal. Officers entered through a porch door, saw Callahan drop a plastic bag later found to contain methamphetamine, and conducted a protective sweep. They recovered drugs, the marked bill, and syringes.
The Utah Court of Appeals vacated Callahan’s conviction after the State conceded there were no exigent circumstances. Callahan then sued the officers under 42 U.S.C. § 1983, alleging a warrantless home entry in violation of the Fourth Amendment. The district court granted summary judgment on qualified immunity, reasoning that officers could reasonably rely on the “consent-once-removed” doctrine. A divided Tenth Circuit panel, following the mandatory Saucier v. Katz sequence, found a clearly established violation. In granting certiorari, the Supreme Court directed the parties to address whether Saucier should be overruled.
The case did not involve a use-of-force encounter. It concerns a warrantless entry and the procedure for deciding qualified immunity.
Core Legal Issue
(1) Whether courts must always follow Saucier’s two-step order, deciding first whether a constitutional right was violated and then whether it was clearly established. (2) Whether officers who entered a home after a consenting informant observed contraband were entitled to qualified immunity.
The Holding
In a unanimous opinion by Justice Alito, the Court held that the Saucier sequence “should not be regarded as an inflexible requirement.” Lower courts may decide which prong to address first. The officers were entitled to qualified immunity because their entry did not violate clearly established law, and the Tenth Circuit’s judgment was reversed.
The Court’s Analysis:
- Qualified immunity shields officials unless their conduct violates “clearly established statutory or constitutional rights of which a reasonable person would have known” (Harlow). It covers mistakes of law, fact, or both, and it is “an immunity from suit rather than a mere defense to liability,” so it should be resolved “at the earliest possible stage in litigation.”
- Stare decisis did not bar reconsidering Saucier. It is a recent, judge-made procedural rule that creates no reliance interests, and it had been widely criticized by Members of the Court and lower-court judges.
- The two-step order is “often beneficial” because it develops constitutional precedent. But a rigid rule wastes judicial and party resources, produces fact-bound rulings of little precedential value, risks poor decisions on thin briefing or undeveloped facts, can insulate adverse constitutional rulings from appeal, and departs from constitutional avoidance.
- On the merits of immunity, when the entry occurred in 2002 the “consent-once-removed” doctrine had been accepted by three federal courts of appeals and two state supreme courts, and no court of appeals had rejected it. “Police officers are entitled to rely on existing lower court cases without facing personal liability,” even before their own circuit has ruled (citing Wilson v. Layne).
