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.
Smith v. California Smith v. California, 361 U.S. 147 (1959), was a U.S. Supreme Court case upholding the freedom of the press. The decision deemed unconstitutional a city ordinance that made one in possession of obscene books criminally liable because it did not require proof that one had knowledge of the book’s content, and thus violated the freedom of the press guaranteed in the First Amendment. "Smith v. California" continued the Supreme Court precedent of ruling that questions of freedom of expression were protected by the Due Process clause of the Fourteenth Amendment from invasion by state action. It also established that in order for one to be criminally liable for possession of obscene material, there must be proof of one’s knowledge of the material.
