Fourth Amendment

“The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.” 

- U.S. Const. amend. IV. 

NACDL seeks to ensure that the Fourth Amendment remains a vibrant protection against encroachments on the privacy of the individual through litigation and public advocacy. The Fourth Amendment is the appropriate starting point for assessing the limits on government intrusion into one’s privacy, and its protections must continue to thrive in the digital age. The Fourth Amendment and its guarantees should not turn on the medium used to transmit private information, nor on how the information is stored. NACDL strives to guarantee that evidence obtained in violation of the Fourth Amendment is excluded in a court of law.
