Police investigating a violent robbery-homicide in Minneapolis developed probable cause to arrest the respondent, Robert Olson, as the getaway driver. On the day of the crime, officers learned Olson was staying as an overnight guest at a private residence. Police surrounded the home and, without obtaining either a warrant or the consent of the occupants, entered and arrested Olson inside. After his arrest, Olson made inculpatory statements. He moved to suppress, arguing that the warrantless, nonconsensual entry into the dwelling to arrest him violated the Fourth Amendment and that, as an overnight guest, he had a reasonable expectation of privacy in the home. The Minnesota Supreme Court agreed, concluding that Olson could challenge the entry and that no exigent circumstances justified it; it suppressed his post-arrest statements as the fruit of the unlawful entry and arrest. The State sought review, and the U.S. Supreme Court granted certiorari.
Does an overnight guest in another person's home have a legitimate expectation of privacy sufficient to challenge a warrantless, nonconsensual entry by police to arrest him, and, if so, were there exigent circumstances that justified the entry without a warrant?
Under the Fourth Amendment, a person may assert a privacy-based challenge to a government intrusion if he had a legitimate expectation of privacy that society is prepared to recognize as reasonable (Katz v. United States; Rakas v. Illinois). A warrantless, nonconsensual entry into a dwelling to effect a routine felony arrest is presumptively unreasonable absent exigent circumstances (Payton v. New York). An overnight guest has a legitimate expectation of privacy in the host's home, and officers may not enter to arrest the guest without a warrant or exigent circumstances.
Yes. An overnight guest has a legitimate expectation of privacy in the host's home. The warrantless, nonconsensual entry to arrest Olson violated the Fourth Amendment because no exigent circumstances justified dispensing with a warrant.
The Court first addressed whether Olson could claim Fourth Amendment protection in a dwelling he did not own, lease, or control. Drawing on the expectation-of-privacy framework, the Court emphasized that spending the night at another's home is a longstanding social custom tied to the core privacy and shelter the home provides. An overnight guest seeks refuge and privacy—sleep, personal hygiene, and the storage of personal effects—activities historically and intuitively associated with protected home life. Society is prepared to recognize as reasonable the expectation that police will not enter a dwelling at will to seize a guest absent a warrant or exigent circumstances. The Court rejected the notion that a lack of property interest or dominion over the premises defeats the expectation; Fourth Amendment privacy does not turn solely on property concepts (citing Katz and Rakas) and has long extended to guests (cf. Jones v. United States). Turning to exigency, the State argued that the gravity of the offense, concern about the suspect's possible flight, and a generalized risk to the public or evidence justified immediate entry. The Court disagreed. The record showed no hot pursuit, no immediate threat to officer or public safety inside the home, no imminent destruction of evidence relevant to the offense, and ample opportunity to secure a warrant; indeed, officers had the house surrounded and controlled the scene. The mere possibility of flight, without more, does not create exigency, especially where police can contain the residence. Because the entry was presumptively unreasonable under Payton and no exigent circumstances displaced the warrant requirement, Olson's arrest in the home violated the Fourth Amendment. The post-arrest statements were properly suppressed as the fruits of the illegal entry and arrest.
Olson firmly recognizes that social relationships and customary uses of dwellings—especially overnight stays—create constitutionally protected privacy interests. It extends Payton's home-entry protections to guests and interfaces with Steagald v. United States, which requires a search warrant to enter a third party's home to execute an arrest warrant for a suspect. Together, these cases underscore that absent consent or genuine exigency, police must obtain appropriate judicial authorization before crossing a home's threshold, whether to seize the resident or a guest. For law students, Olson is essential for understanding Fourth Amendment "standing," the social norms that inform reasonable expectations of privacy, and how courts scrutinize claimed exigent circumstances. It also sets the stage for Minnesota v. Carter, which limits protection for short-term, primarily commercial visitors, highlighting context-specific privacy analysis.
Minnesota v. Olson expanded and clarified the scope of Fourth Amendment protection by recognizing that overnight guests share in the home's constitutional shield. Police cannot leverage the 'third-party' setting to avoid the warrant requirement when they seek to arrest an overnight guest inside a dwelling, unless genuine exigent circumstances exist.
