The Sacred Fourth Amendment Text, Christopher Slobogin Oct 2020

The Sacred Fourth Amendment Text, Christopher Slobogin

Michigan Law Review Online

The Supreme Court’s jurisprudence governing the Fourth Amendment’s “threshold”—a word meant to refer to the types of police actions that trigger the amendment’s warrant and reasonableness requirements—has confounded scholars and students alike since Katz v. United States. Before that 1967 decision, the Court’s decisions on the topic were fairly straightforward, based primarily on whether the police trespassed on the target’s property or property over which the target had control. After that decision—which has come to stand for the proposition that a Fourth Amendment search occurs if police infringe an expectation of privacy that society is prepared to recognize as …


How Definitive Is Fourth Amendment Textualism?, Evan H. Caminker Oct 2020

How Definitive Is Fourth Amendment Textualism?, Evan H. Caminker

Michigan Law Review Online

Professor Jeffrey Bellin’s excellent article advances a comprehensive and straightforward textual approach to determining what policing activities constitute “searches” triggering the protections of the Fourth Amendment. Bellin’s thesis is that a text-based approach to interpreting the Amendment is superior to the Supreme Court’s current approach, which ever since Katz v.

United States, which defines “search” as government conduct that violates subjectively manifested expectations of privacy “that society is prepared to recognize as ‘reasonable.’ ” This is pure applesauce. Nowhere will you find a standard dictionary that defines “search” in these terms. Neither will you hear a native speaker of the English language use “search” in this sense unless her mind has been polluted by a semester of studying criminal procedure. The Court created this definition …


Soundings And Silences, Laurence H. Tribe Jan 2016

Soundings And Silences, Laurence H. Tribe

Michigan Law Review Online

My work over the years has included both studying existing constitutions, particularly that of the United States, and assisting others with the drafting of new constitutions—from the Marshall Islands to the Czech Republic to South Africa. Among the things I noticed was that those undertakings, although distinct, were related—and related most significantly in the way that formative decisions about what to say and what not to say in a new constitution have bearing on later decisions about how to interpret what a constitution says or fails to say. My decision to pay special attention to the various roles of silence …
