Minnesota v. Olson, 495 U.S. 91 (1990) (U.S. Supreme Court)
Minnesota v. Olson is a cornerstone Fourth Amendment case that clarifies who may claim the Amendment's protections inside a dwelling.
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.
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.
