Which landmark case first applied the Exclusionary Rule to state courts?

• A. Mapp v. Ohio
• B. Miranda v. Arizona
• C. Gideon v. Wainwright
• D. Miller v. California

Answer: (A)

The crucial idea here is how the Exclusionary Rule extends to state courts. The Exclusionary Rule bars evidence obtained through illegal searches from being used in court. It began for federal prosecutions with Weeks v. United States (1914). The question asks which case first brought that rule to the states, and the answer is Mapp v. Ohio (1961). In Mapp, the Supreme Court ruled that the Fourth Amendment's protections against unreasonable searches and seizures must be applied to state governments as well, using the Fourteenth Amendment’s Due Process Clause to incorporate the right. This made illegal evidence inadmissible in state courts just as it is in federal courts. The other cases involve different constitutional protections. Miranda v. Arizona deals with the right to counsel and interrogation practices, Gideon v. Wainwright guarantees counsel for defendants, and Miller v. California sets standards for obscenity. None of these address applying the Exclusionary Rule to state courts, which is why they aren’t the correct choice in this context.
