Were Schmerber v. California and Muller v. Oregon decided in the same year?
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. Butler United States v. Butler, 297 U.S. 1 (1936) , was a case in which the Supreme Court of the United States ruled that the processing taxes instituted under the 1933 Agricultural Adjustment Act were unconstitutional. Justice Owen Roberts argued that the tax was "but a means to an unconstitutional end" that violated the Tenth Amendment.
