Anderson v. Creighton
The Supreme Court ruled that an FBI agent sued for a warrantless home search could claim qualified immunity even if the search actually violated the Fourth Amendment, as long as a reasonable officer in his position could have believed probable cause and an emergency justified the search.
The decision sharpens how courts must define a 'clearly established right' in immunity cases, requiring a fact-specific, particularized inquiry rather than a broad rule, making it harder for people to sue individual officers for constitutional violations.
“The contours of the right must be sufficiently clear that a reasonable official would understand that what he is doing violates that right.”
The Court's core test for when a right is 'clearly established' for qualified immunity purposes.
How it got here: A federal trial court granted the agent summary judgment; the Eighth Circuit reversed, and the agent asked the Supreme Court to review the immunity ruling.
The Case in Depth
What happened
An FBI agent and other officers searched the home of the Creighton family without a warrant, looking for a bank robbery suspect who was not there. The family sued the agent for money damages, claiming the warrantless search violated their Fourth Amendment rights. The agent argued he should be shielded from personal liability because he reasonably believed his conduct was lawful at the time.
The question before the Court
If an FBI agent's warrantless home search violated the Fourth Amendment, can he still avoid a damages lawsuit if a reasonable officer could have thought the search was lawful?
Why it matters
People whose homes are searched without a warrant may find it harder to collect money damages from the individual officers involved, even when a court later finds the search unconstitutional, because officers can escape liability by showing a reasonable colleague could have made the same mistake. The ruling shapes how lower courts screen civil-rights suits against police and federal agents before allowing any discovery.
What changes now
The case returns to the lower courts to apply the newly clarified, fact-specific immunity standard: first deciding whether the conduct the family alleges was conduct a reasonable officer could have believed lawful, and if so, dismissing the claim before any discovery. If not, and if the agent's own account differs from the family's, limited discovery tailored to the immunity question may proceed. The underlying question of whether the search actually violated the Fourth Amendment remains unresolved.
What this does not decide
The Court does not decide whether the search of the Creightons' home actually violated the Fourth Amendment, nor does it resolve any factual disputes about what happened during the search. It only clarifies the legal standard for qualified immunity and sends the case back for further proceedings under that standard.
Concurrences and dissents
Dissent — Justice Stevens
“an official search and seizure cannot be both `unreasonable' and `reasonable' at the same time.”Stevens's objection to letting officers escape liability for searches the Court assumes were unconstitutional.
Justice Stevens argued the majority created an unjustified 'double standard of reasonableness' that lets officers escape liability even when their conduct is unconstitutional. He contended that Harlow-style immunity, designed for high executive officials facing abstract legal uncertainty, does not fit fact-specific Fourth Amendment claims by law enforcement officers in the field, and would have affirmed the Eighth Circuit's decision to let the case proceed to discovery and trial, potentially leaving room for a good-faith defense at trial rather than blanket pretrial immunity.
How the Court got there
The legal reasoning, step by step
- The Court applied its qualified immunity framework, which shields officials from personal damages liability unless their conduct violated a 'clearly established' right — one whose contours are specific enough that a reasonable official would know the conduct was unlawful.
- The Court explained that this standard must be assessed at a particularized level tied to the facts, not at the level of a broad constitutional guarantee, because testing immunity against an abstract right would turn every constitutional claim into a viable damages suit and gut the purpose of immunity.
- Applying this to Fourth Amendment claims, the Court reasoned that even though the requirement of probable cause and exigent circumstances for warrantless home searches was clearly established in the abstract, that alone does not answer whether it was clearly unreasonable for this particular officer to believe his specific search satisfied those requirements.
- The Court held that officers who reasonably but mistakenly conclude that probable cause or an emergency justification exists should not be personally liable, so long as their belief was objectively reasonable in light of the information they had and the clearly established law at the time.
- The Court rejected the family's argument that Fourth Amendment claims should be treated differently from other constitutional claims for immunity purposes, noting the Court had already applied qualified immunity to other Fourth Amendment cases and finding no principled basis to carve out an exception for warrantless home searches of innocent third parties.

The Court leans on Mitchell as confirming that qualified immunity applies even to alleged Fourth Amendment violations like warrantless wiretaps.
Reaffirms Malley v. Briggs (475 U. S. 335)
The Court relies on Malley as establishing that officers seeking warrants get immunity if a reasonable officer could have believed probable cause existed.
