Mapp v Ohio, 367 U.S. 643 (1961), is a landmark United States Supreme Court decision holding that the exclusionary rule, which bars prosecutors from using evidence obtained in violation of the Fourth Amendment, applies to the states as well as the federal government, through the Fourteenth Amendment's Due Process Clause. The case arose after Cleveland police searched Dollree Mapp's home without a valid warrant and found materials used to convict her.
