Question: 1 / 400

Which Supreme Court case established the "Exclusionary Rule"?

New Jersey v. T.L.O.

Mapp v. Ohio

The Exclusionary Rule, which prohibits the use of evidence obtained in violation of a defendant's constitutional rights, was established in the Supreme Court case known as Mapp v. Ohio. This landmark decision extended the exclusionary rule, which was originally applicable only to federal cases, to state courts, thereby ensuring that evidence obtained illegally—or without a proper warrant—could not be used to prosecute individuals in any court across the United States. The ruling underscored the importance of protecting Fourth Amendment rights against unreasonable searches and seizures, reinforcing the principle that law enforcement must adhere to legal standards when conducting investigations. This case set a crucial precedent in American jurisprudence, emphasizing the necessity of maintaining due process and protecting citizens' rights against unlawful government intrusion.
