Mapp v. Ohio

Summary

The United States Supreme Court held that evidence obtained through an unconstitutional search and seizure is inadmissible in state criminal proceedings. Overruling Wolf v. Colorado, the Court concluded that the Fourth Amendment exclusionary rule applies to the states through the Fourteenth Amendment. The Court reversed the judgment of the Supreme Court of Ohio and remanded the case.

Holdings

2. A state conviction based on evidence obtained through an unconstitutional search and seizure cannot stand.

Questions Presented

1. Whether the Fourteenth Amendment makes the Fourth Amendment exclusionary rule applicable to state criminal prosecutions.
