What legal principle does the case Map v. Ohio establish?

The case Map v. Ohio is significant for establishing the Exclusionary Rule at the state level. This legal principle dictates that evidence obtained in violation of a person's constitutional rights cannot be used in court. Originally, this rule applied only to federal cases, but the Supreme Court's decision in Map v. Ohio extended it, ensuring that evidence seized unconstitutionally is inadmissible in state courts as well. This case reinforced the protection against unreasonable searches and seizures as guaranteed by the Fourth Amendment, therefore upholding an individual's right to privacy and due process. The impact of this ruling has profound implications for law enforcement practices and the judicial system, as it compels officers to adhere to constitutional guidelines to ensure that evidence is gathered lawfully.
