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.
United States v. Wurzbach United States v. Wurzbach, 280 U.S. 396 (1930), is a unanimous ruling by the US Supreme Court that the term "political purpose," as used in the Federal Corrupt Practices Act, was not impermissibly vague. The Supreme Court reversed the district court, which had quashed an indictment under the Act.
