Fourth Amendment Protection For Stored E-Mail, Susan Freiwald, Patricia L. Bellia Dec 2007

Fourth Amendment Protection For Stored E-Mail, Susan Freiwald, Patricia L. Bellia

Susan Freiwald

The question of whether and how the Fourth Amendment regulates government access to stored e-mail remains open and pressing. A panel of the Sixth Circuit recently held in Warshak v.
