Q1: What area of law does Maryland v. Buie primarily address?
Criminal Procedure (Fourth Amendment/Search and Seizure)
Q2: What was the central legal issue in Maryland v. Buie?
Does the Fourth Amendment permit officers, incident to executing an arrest warrant inside a suspect's home, to conduct a limited protective sweep of the premises without a search warrant, and if so, what quantum of suspicion and scope govern such a sweep?
Q3: What rule did the court apply?
Incident to an in-home arrest, officers may conduct a protective sweep of the residence under a two-tier standard: (1) Without probable cause or reasonable suspicion, officers may, as a precautionary matter, look in closets and other spaces immediately adjoining the place of arrest from which an attack could be immediately launched. (2) To extend the sweep beyond immediately adjoining spaces, officers must have specific, articulable facts, which, taken together with rational inferences from those facts, would warrant a reasonably prudent officer in believing that the area to be swept harbors an individual posing a danger. The sweep is a cursory inspection only of places where a person might hide and may last no longer than is necessary to dispel the reasonable suspicion of danger and to complete the arrest and depart the premises. Items observed in plain view during a lawful protective sweep may be seized.
Q4: What was the court's holding?
Yes. The Fourth Amendment permits a limited protective sweep of a home incident to an in-home arrest under the standards above. The Supreme Court reversed the judgment of the Maryland Court of Appeals and remanded for further proceedings consistent with this rule.
Q5: Why is Maryland v. Buie significant?
Buie is central to the law of search and seizure because it defines a discrete, limited safety search within the most protected space—the home. It operationalizes the officer-safety rationale in a way that coexists with the strong presumption against warrantless home searches by demanding articulable facts for sweeps beyond immediately adjoining spaces and by sharply limiting scope and duration. For students, Buie often appears alongside Chimel and Terry to test whether one can parse distinct justifications (incident-to-arrest versus protective sweep), apply tiered suspicion thresholds, and police the boundary between permissible person-locating sweeps and impermissible evidence-gathering searches.
