The Search And Seizure Of Private Papers: Fourth And Fifth Amendment Considerations, Steven Shiffrin Jun 2015

The Search And Seizure Of Private Papers: Fourth And Fifth Amendment Considerations, Steven Shiffrin

Steven H. Shiffrin

There is a recognizable factual distinction between the search and seizure of private papers and the search and seizure of non-documentary items. It is difficult, however, to decide when such a distinction should assume constitutional dimensions. Specifically, are there circumstances under which private papers should be immune from search and seizure? In a 1967 landmark case, Warden v. Hayden, the United States Supreme Court raised doubts concerning the continued validity of decades of settled law on this important issue. Warden's reopening of this problem aroused the curiosity of commentators, spurred new policy arguments in the American Law Institute, divided the …


Cell Phone Location Data And The Fourth Amendment: A Question Of Law, Not Fact, Susan Freiwald Dec 2010

Cell Phone Location Data And The Fourth Amendment: A Question Of Law, Not Fact, Susan Freiwald

Susan Freiwald

In a significant ruling in the fall of 2010, the Third Circuit Court of Appeals rejected the government’s claim that it could compel cell phone service providers to disclose customer records that indicate the cell towers with which a cell phone has communicated (cell phone location information or CSLI) without obtaining a warrant based on probable cause. In a break with past decisions, the court rejected application of a “third party rule,” under which cell phone users are seen to assume the risk that their providers will disclose location data without the protections of a warrant requirement. The court, however, …


Moving Targets: Placing The Good Faith Doctrine In The Context Of Fragmented Policing, Hadar Aviram, Richard Leo, Jeremy Seymour Dec 2009

Moving Targets: Placing The Good Faith Doctrine In The Context Of Fragmented Policing, Hadar Aviram, Richard Leo, Jeremy Seymour

Richard A. Leo

The debate sparked by Herring v. United States is a microcosm of the quintessential debate about the scope of the Fourth Amendment’s exclusionary rule and ultimately the appropriate breadth of police authority and constitutional review by courts. Offering a new reading of the decision, this article argues that Herring reflects a healthy dosage of real politik and an acknowledgement that American policing is characterized by a fragmented, localized structure with little overview and control, and much reliance on local agencies. Part I presents the authors’ interpretation of Herring as a case hinging upon the question “who made the mistake?” as …


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. United States, 490 F.3d 455 (6th Cir. 2007), that users generally retain a reasonable expectation of privacy in the e-mails they store with their Internet Service Providers (ISPs), which implies that government agents must generally acquire a warrant before they may compel ISPs to disclose their users' stored e-mails. The Sixth Circuit, however, is reconsidering the case en banc. This Article examines the nature of stored e-mail surveillance and argues …


Electronic Surveillance At The Virtual Border, Susan Freiwald Dec 2007

Electronic Surveillance At The Virtual Border, Susan Freiwald

Susan Freiwald

A virtual border divides people into two groups: those subject to the Fourth Amendment’s protections when the U.S. government conducts surveillance of their communications and those who are not. The distinction derives from a separation in powers: inside the virtual border, U.S. citizens and others enjoy the extensive oversight of the judiciary of executive branch surveillance. Judges review such surveillance before, during, and after it transpires. Foreign persons subject to surveillance in foreign countries fall within the executive branch’s’ foreign affairs function. However, the virtual border does not exactly match the physical border of the United States. Some people inside …


The Fourth Amendment Status Of Stored E-Mail: The Law Professors’ Brief In Warshak V. United States, Susan Freiwald, Patricia L. Bellia Dec 2006

The Fourth Amendment Status Of Stored E-Mail: The Law Professors’ Brief In Warshak V. United States, Susan Freiwald, Patricia L. Bellia

Susan Freiwald

This paper contains the law professors' brief in the landmark case of Warshak v. United States, the first federal appellate case to recognize a reasonable expectation of privacy in electronic mail stored with an Internet Service Provider (ISP). While the 6th circuit's opinion was subsequently vacated and reheard en banc, the panel decision will remain extremely significant for its requirement that law enforcement agents must generally acquire a warrant before compelling an ISP to disclose its subscriber's stored e-mails. The law professors' brief, co-authored by Susan Freiwald (University of San Francisco) and Patricia L. Bellia (Notre Dame) and signed by …


A First Principles Approach To Communications' Privacy, Susan Freiwald Dec 2006

A First Principles Approach To Communications' Privacy, Susan Freiwald

Susan Freiwald

Under current doctrines, parties to a communication enjoy robust constitutional protection against government surveillance only when they have a reasonable expectation of privacy in those communications. This paper suggests that the surprising dearth of case law applying the reasonable expectations of privacy test to modern electronic communications reflects courts' discomfort with the test's necessarily normative analysis. That discomfort also likely explains courts' use of shortcuts based on Miller v. United States and Smith v. Maryland in those few cases that have considered online surveillance practices. In particular, the government has argued that a broad third party rule deprives electronic mail …
