Which case is associated with applying the exclusionary rule to state actions?

• A. Mapp v. Ohio
• B. Wong Sun v. United States
• C. Miranda v. Arizona
• D. Brown v. Board of Education

Answer: (A)

Applying the exclusionary rule to state actions is achieved through incorporating the Fourth Amendment’s protections against unreasonable searches and seizures into state prosecutions via the Fourteenth Amendment. Mapp v. Ohio held that the exclusionary rule, which bars illegally obtained evidence, applies to state as well as federal cases, so evidence obtained in violation of the Fourth Amendment cannot be used in state courts. This established the nationwide reach of the rule into state actions. Wong Sun v. United States deals with how tainted evidence and statements are treated in federal cases and the broader limits of the exclusionary rule, but it does not establish state incorporation. Miranda v. Arizona concerns the rights of suspects during interrogation and the right to counsel, not the exclusionary rule’s application to states. Brown v. Board of Education addresses desegregation and equal protection, unrelated to evidence suppression. Therefore, the case that ties the exclusionary rule to state actions is Mapp v. Ohio.
