Amdt4.6.3 Exigent Circumstances and Warrants

Fourth Amendment:

The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

The Court has recognized “the exigencies of the situation” as an exception to the warrant requirement, which “make the needs of law enforcement so compelling that the warrantless search is objectively reasonable under the Fourth Amendment.” 1 Exigent circumstances requires a court “to examine whether an emergency justified a warrantless search in each particular case.” 2 The Court has identified several types of circumstances that give rise to an exigency sufficient to justify a warrantless search, including a search incident to arrest,3 law enforcement’s need to provide emergency aid,4 “hot pursuit” of a fleeing suspect,5 and the prevention of the imminent destruction of evidence.6 In situations absent dangerous and life-threatening circumstances, the Court recognizes that warrantless searches are permissible in circumstances where “there is a compelling need for official action and no time to secure a warrant.” 7

The Court has refused to adopt a categorical rule as to what circumstances constitutes an exigency and, instead, applies a case-by-case analysis dependent on “all of the facts and circumstances of the particular case.” 8 To determine whether exigent circumstances existed to justify a warrantless search, the Court “looks to the totality of circumstances.” 9 In rendering emergency assistance, the officer must have “an objectively reasonable basis for believing” that an individual within the home was in need of immediate assistance.10 When the police, in executing a warrantless search, have not created the exigency in question, the Court has held that such “warrantless entry to prevent the destruction of evidence is reasonable and thus allowed.” 11 In contrast, the Court in Johnson v. United States rejected the government’s claim that exigent circumstances justified a warrantless search of an individual’s home.12 In Johnson, the police gained entry into the suspect’s home after a “demand[ ] under color of office.” 13 The Court, in rejecting the government’s claim that the search was conducted because of the “opium smell in the room,” held that the government offered no reason “for not obtaining a search warrant except the inconvenience to the officers and some slight delay necessary to prepare papers and present the evidence to a magistrate.” 14 The Court reasoned that “[t]hese are never very convincing reasons and, in these circumstances, certainly are not enough to by-pass the constitutional requirement. No suspect was fleeing or likely to take flight. The search was of permanent premises, not of a movable vehicle. No evidence or contraband was threatened with removal or destruction, except perhaps the fumes which [the Court] suppose[d] in time would disappear.” 15

In terms of determining the reasonableness for the police to proceed without a warrant when they are in hot pursuit of a suspect, the Court has held that, in such circumstances, “the need to act quickly . . . is even greater . . . while the intrusion is much less.” 16 For example, the Court has held that the “ Fourth Amendment does not require police officers to delay in the course of an investigation if to do so would gravely endanger their lives or the lives of others.” 17 In Lange v. California, the Court reiterated that the exigent circumstances exception is generally applied on a “case-by-case basis,” 18 and declined to hold that pursuing a misdemeanor suspect categorically qualifies as an exigent circumstance exception to the warrant requirement.19
