Steagald v. United States, 451 U.S. 204 (1981)
Syllabus
Pursuant to an arrest warrant for one Lyons, Drug Enforcement Administration agents entered petitioner’s home to search for Lyons without first obtaining a search warrant. In the course of searching the home, the agents found cocaine and other incriminating evidence, but did not find Lyons. Petitioner was then arrested and indicted on federal drug charges. His pretrial motion to suppress all evidence uncovered during the search of his home on the ground that it was illegally obtained because the agents had failed to obtain a search warrant was denied by the District Court, and petitioner was convicted. The Court of Appeals affirmed.
Held:
1. The Government is precluded from contending in this Court that petitioner lacked an expectation of privacy in his searched home sufficient to prevail on his Fourth Amendment claim where this argument was never raised in the courts below, but, rather, the Government had made contrary assertions in those courts, and acquiesced in their contrary findings. Pp.  451 U. S. 208-211.
2. The search in question violated the Fourth Amendment where it took place in the absence of consent or exigent circumstances. Pp.  451 U. S. 211-222.
(a) Absent exigent circumstances or consent, a home may not be searched without a warrant. Two distinct interests were implicated by the search in this case — Lyons’ interest in being free from an unreasonable seizure and petitioner’s interest in being free from an unreasonable search of his home. Because the arrest warrant for Lyons addressed only the former interest, the search of petitioner’s home was no more reasonable from petitioner’s perspective than it would have been if conducted in the absence of any warrant. The search therefore violated the Fourth Amendment. Pp.  451 U. S. 211-216.
(b) Common law, contrary to the Government’s assertion, does not furnish precedent for upholding the search in question, but rather sheds little light on the narrow issue presented of whether an arrest warrant, as opposed to a search warrant, is adequate to protect the Fourth Amendment interests of persons not named in the warrant when their home is searched without their consent and in the absence of exigent

circumstances. Moreover, the history of the Fourth Amendment strongly suggests that its Framers would not have sanctioned the search in question. Pp.  451 U. S. 217-220.
(e) A search warrant requirement, under the circumstances of this case, will not significantly impede effective law enforcement efforts. An arrest warrant alone suffices to enter a suspect’s own residence, and, if probable cause exists, no warrant is required to apprehend a suspected felon in a public place. Moreover, the exigent circumstances doctrine significantly limits the situations in which a search warrant is needed. And in those situations in which a search warrant is necessary, the inconvenience incurred by the police is generally insignificant. In any event, whatever practical problems there are in requiring a search warrant in cases such as this, they cannot outweigh the constitutional interest at stake in protecting the right of presumptively innocent people to be secure in their homes from unjustified forcible intrusions by the government. Pp.  451 U. S. 220-222.
