Supreme Court of the United States

Mapp appeals her conviction to the Court, which agrees to hear her case. The Court accepts Mapp's argument that the evidence gained during the illegal search of her house could not be used to convict her. Thus, the Fourth Amendment exclusionary rule applies to the states. Mapp's conviction is overturned.
