What it's about

The Supreme Court held that this exception, which had been recognized in the vehicle context, does not extend to the home.

The case tested whether a rule developed for police work around cars could be used inside a home, where the Fourth Amendment ordinarily requires a warrant.

Question presented

Whether the "community caretaking'' exception to the Fourth Amendment's warrant requirement extends to the home?

What the Court decided

Holding

Neither the holding nor logic of Cady justifies such warrantless searches and seizures in the home. Cady held that a warrantless search of an impounded vehicle for an unsecured firearm did not violate the Fourth Amendment. In reaching this conclusion, the Court noted that the officers who patrol the “public highways” are often called to discharge noncriminal “community caretaking functions,” such as responding to disabled vehicles or investigating accidents. 413 U. S., at 441. But searches of vehicles and homes are constitutionally different, as the Cady opinion repeatedly stressed. Id., at 439, 440– 442. 953 F. 3d 112, vacated and remanded.
