exigent circumstances

Overview

Exigent circumstances, as defined in United States v. McConney are "circumstances that would cause a reasonable person to believe that entry (or other relevant prompt action) was necessary to prevent physical harm to the officers or other persons, the destruction of relevant evidence, the escape of the suspect, or some other consequence improperly frustrating legitimate law enforcement efforts." 

Application

Exigent circumstances are essentially exceptions to the general requirement of a warrant  under the Fourth Amendment  searches and seizures .  

In Missouri v. McNeely (2013), the Supreme Court clarified, "A variety of circumstances may give rise to an exigency sufficient to justify a warrantless search, including law enforcement's need to provide emergency assistance to an occupant of a home . . . engage in “hot pursuit” of a fleeing suspect . . . or enter a burning building to put out a fire and investigate its cause." 

Courts will typically look at the time when the officer makes the warrantless search or seizure  to evaluate whether at that point in time a reasonable  officer at the scene would believe it is urgent to act and impractical to secure a warrant . Courts may also consider whether the facts suggested that the suspect was armed and planning to escape, whether a reasonable  police officer would believe their safety or others’ safety was threatened, and whether there was a serious crime involved.

Exigent circumstances may also occur when the police is in hot pursuit  of a suspect who is possibly involved in criminal activities and in the process of fleeing. (See Michigan v. Fisher, 558 U.S. 45 (2009) )
