Developed during the 1970’s, the third-party doctrine states that one has no reasonable expectation of privacy regarding information that they voluntarily disclose to third parties. The Government can therefore access this information without a warrant. However, the cases giving rise to that doctrine misapplied well established Fourth Amendment law.
In addition, recent Supreme Court decisions make it clear that a proper Fourth Amendment analysis requires a consideration of the quality and quantity of data involved. Given the monumental differences in both the quality and quantity of data stored with third parties today as opposed to 40 years ago, the third-party doctrine is no longer applicable in modern society. Consequently, the Government should be required to obtain a warrant before obtaining data stored with third parties.
