Steven G. Friedman—Senior Attorney, National Legal Research Group
The Fourth Amendment to the United States Constitution protects citizens from unreasonable searches and seizures of their persons or property. See U.S. Const. amend. IV. The exclusionary rule prohibits the use of evidence obtained in violation of the Fourth Amendment. See United States v. Calandra, 414 U.S. 338, 347 (1974). However, the exclusionary rule does not apply to all proceedings or against all persons and is generally restricted to areas in which the goal of deterring unlawful police conduct is "most efficaciously served." Id. at 348. In determining whether the exclusionary rule applies, the U.S. Supreme Court has developed a balancing test whereby courts weigh the likely social benefits of excluding unlawfully obtained evidence against the possible costs. See INS v. Lopez Mendoza, 468 U.S. 1032, 1041 (1984).
