Which case United States v. Wong Kim Ark or  Schmerber v. California was decided first ?
Schmerber v. California Schmerber v. California, 384 U.S. 757 (1966) , was a landmark United States Supreme Court case in which the Court clarified the application of the Fourth Amendment's protection against warrantless searches and the Fifth Amendment privilege against self-incrimination for searches that intrude into the human body. Until "Schmerber", the Supreme Court had not yet clarified whether state police officers must procure a search warrant before taking blood samples from criminal suspects. Likewise, the Court had not yet clarified whether blood evidence taken against the wishes of a criminal suspect may be used against that suspect in the course of a criminal prosecution.
California v. Acevedo California v. Acevedo, 500 U.S. 565 (1991), was a decision of the United States Supreme Court, which interpreted the "Carroll" doctrine to provide one rule to govern all automobile searches. The Court stated, "The police may search an automobile and the containers within it where they have probable cause to believe contraband or evidence is contained." The decision also overruled the distinctions in "United States v. Chadwick" (1977) and "Arkansas v. Sanders" (1979) which had previously held that, if probable cause existed to search an automobile, the police may perform a warrantless search of the automobile and the containers within it, but if the police only had probable cause to search a container in the automobile, the police first had to obtain a warrant before searching the container.
