In their decision, the court ruled in favor of Mapp and overturned her conviction. In the 6-3 decision, the court found the states were also required to exclude evidence seized in violation of a person's Fourth Amendment rights. They stated that any evidence obtained in searches and seizures that violated the Constitution were not admissible in state courts. Otherwise, there would be no right against unreasonable search and seizure. Associate justice Tom C. Clark delivered the majority opinion.
