Which Supreme Court case ruled that evidence collected outside of legal search parameters cannot be used in court?

Mapp v. Ohio is significant because it established the exclusionary rule, which mandates that evidence obtained in violation of the Fourth Amendment's protection against unreasonable searches and seizures cannot be used in court. This landmark decision was pivotal in ensuring that law enforcement must follow legal procedures when collecting evidence. In the case, the Supreme Court ruled that the evidence obtained by police during an illegal search of Dollree Mapp's home was inadmissible, reinforcing the principle that unlawful searches compromise the integrity of the judicial process. This ruling extended the exclusionary rule to state courts, which became essential in protecting individuals' rights against governmental overreach.
