United States v. Chadwick, 433 U.S. 1 (1977), was a decision by the United States Supreme Court, which held that, absent , the warrantless search of double-locked luggage just placed in the trunk of a parked vehicle is a violation of the Fourth Amendment and not justified under the automobile exception. The Court reasoned that while luggage is movable like an automobile, it does not have the lesser expectation of privacy associated with an automobile. The holding in Chadwick that a search incident to arrest must not be too remote in time or place is still good law.
