Definition

Wolf v. Colorado is a landmark Supreme Court case from 1949 that dealt with the applicability of the Fourth Amendment's protections against unreasonable searches and seizures to the states through the Fourteenth Amendment. The Court held that while the exclusionary rule, which prevents illegally obtained evidence from being used in court, was not mandatory for state courts, states were still required to uphold the Fourth Amendment's protections. This case is significant as it played a crucial role in shaping the incorporation doctrine, which aims to apply federal rights at the state level.
