“Are We There Yet?”: The Long Journey To Defining Motor Home Protections Under The Fourth Amendment, Ilse Ghent Mar 2025

“Are We There Yet?”: The Long Journey To Defining Motor Home Protections Under The Fourth Amendment, Ilse Ghent

Arkansas Law Review

From the time of the Revolutionary War, United States citizens have prioritized one thing over almost everything else: that “a man’s house is his castle.” This is immortalized in the Fourth Amendment’s prohibition against unreasonable and warrantless searches. The protections granted by the Fourth Amendment are not centered around the rights a person has in their property. Instead, “the principal object of the Fourth Amendment is the protection of privacy rather than property.” This protection is so important that the Supreme Court has been explicitly clear that warrantless searches should only be permitted in the most “exceptional” of circumstances. One …


The Empty Promise Of The Fourth Amendment In The Family Regulation System, Anna Arons Jan 2023

The Empty Promise Of The Fourth Amendment In The Family Regulation System, Anna Arons

Faculty Publications

Each year, state agents search the homes of hundreds of thousands of families across the United States under the auspices of the family regulation system. Through these searches—required elements of investigations into allegations of child maltreatment in virtually every jurisdiction—state agents invade the home, the most protected space in Fourth Amendment jurisprudence. Accordingly, federal courts agree that the Fourth Amendment’s warrant requirement applies to family regulation home searches. But almost universally, the abstract recognition of Fourth Amendment protections runs up against a concrete expectation on the ground that state actors should have easy and expansive access to families’ homes. Legislatures …


Border Searches For Investigatory Purposes: Implementing A Border Nexus Standard, Brenna Ferris Jun 2021

Border Searches For Investigatory Purposes: Implementing A Border Nexus Standard, Brenna Ferris

University of Michigan Journal of Law Reform Caveat

Border searches are a commonly used exception to the Fourth Amendment’s probable cause and warrant requirements. Using a border search, the government can conduct searches of individuals without any kind of individualized suspicion. Border searches pose a concerning risk to privacy when they are used as a tool for criminal investigations. The Supreme Court has never ruled on searches used in this way, but lower courts are addressing the technique and reaching conflicting decisions. Courts need to take an approach that will protect the privacy interests of individuals while allowing the government to advance its interests in protecting its borders …


The Genetic Panopticon: Genetic Genealogy Searches And The Fourth Amendment, Genevieve Carter May 2021

The Genetic Panopticon: Genetic Genealogy Searches And The Fourth Amendment, Genevieve Carter

Northwestern Journal of Technology and Intellectual Property

As consumer DNA testing gains widespread popularity, so has law enforcement’s interest in leveraging genetic databases for criminal investigations. Consumer DNA testing products like 23andMe and Ancestry allow private individuals access to their genetic data on private databases. However, once coded, genetic data is free to be downloaded by users and uploaded to public databases. Police identify suspects by uploading cold case DNA to public genetic databases and find familial matches. If they identify a familial match, they narrow the field of suspects using traditional methods of investigation, which often includes extracting suspect DNA from a piece of their abandoned …


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 has defined “search” primarily by reference to a non-textual “reasonable expectation of privacy” standard. After soundly criticizing the ungrounded and highly subjective nature of the Katz test, Bellin declares that the Court should instead simply follow where the text leads: the Amendment protects people from a search, meaning …


Location Tracking And Digital Data: Can Carpenter Build A Stable Privacy Doctrine?, Evan H. Caminker Jun 2019

Location Tracking And Digital Data: Can Carpenter Build A Stable Privacy Doctrine?, Evan H. Caminker

Articles

In Carpenter v United States, the Supreme Court struggled to modernize twentieth-century search and seizure precedents for the “Cyber Age.” Twice previously this decade the Court had tweaked Fourth Amendment doctrine to keep pace with advancing technology, requiring a search warrant before the government can either peruse the contents of a cell phone seized incident to arrest or use a GPS tracker to follow a car’s long-term movements.


The Quantum Of Suspicion Needed For An Exigent Circumstances Search, Kit Kinports Apr 2019

The Quantum Of Suspicion Needed For An Exigent Circumstances Search, Kit Kinports

University of Michigan Journal of Law Reform

For decades, the United States Supreme Court opinions articulating the standard of exigency necessary to trigger the exigent circumstances exception to the Fourth Amendment’s warrant requirement have been maddeningly opaque and confusing. Some cases require probable cause, others call for reasonable suspicion, and still, others use undefined and unhelpful terms such as “reasonable to believe” in describing how exigent the situation must be to permit the police to proceed without a warrant. Not surprisingly, the conflicting signals coming from the Supreme Court have led to disagreement in the lower courts.

To resolve this conflict and provide guidance to law enforcement …


Carpenter's Legacy: Limiting The Scope Of The Electronic Private Search Doctrine, Sarah A. Mezera Jan 2019

Carpenter's Legacy: Limiting The Scope Of The Electronic Private Search Doctrine, Sarah A. Mezera

Michigan Law Review

One of the most significant challenges confronting courts and legal scholars in the twenty-first century is the application of Fourth Amendment doctrine to new technology. The circuit split over the application of the private search doctrine to electronic devices exemplifies how courts struggle to apply old doctrines to new circumstances. Some courts take the position that the old doctrine should apply consistently in the new context. Other courts have changed the scope of the old doctrine in order to account for the change in circumstances. The Supreme Court took the latter position in Carpenter v. United States and held that …


Fourth Amendment Textualism, Jeffrey Bellin Jan 2019

Fourth Amendment Textualism, Jeffrey Bellin

Michigan Law Review

The Fourth Amendment’s prohibition of “unreasonable searches” is one of the most storied constitutional commands. Yet after decades of Supreme Court jurisprudence, a coherent definition of the term “search” remains surprisingly elusive. Even the justices know they have a problem. Recent opinions only halfheartedly apply the controlling “reasonable expectation of privacy” test and its wildly unpopular cousin, “third-party doctrine,” with a few justices in open revolt.

These fissures hint at the Court’s openness to a new approach. Unfortunately, no viable alternatives appear on the horizon. The justices themselves offer little in the way of a replacement. And scholars’ proposals exhibit …


Secret Searches: The Sca's Standing Conundrum, Aviv S. Halpern Jan 2019

Secret Searches: The Sca's Standing Conundrum, Aviv S. Halpern

Michigan Law Review

The Stored Communications Act (“SCA”) arms federal law enforcement agencies with the ability to use a special type of warrant to access users’ electronically stored communications. In some circumstances, SCA warrants can require service providers to bundle and produce a user’s electronically stored communications without ever disclosing the existence of the warrant to the individual user until charges are brought. Users that are charged will ultimately receive notice of the search after the fact through their legal proceedings. Users that are never charged, however, may never know that their communications were obtained and searched. This practice effectively makes the provisions …


Forensic Border Searches After Carpenter Require Probable Cause And A Warrant, Christopher I. Pryby Jan 2019

Forensic Border Searches After Carpenter Require Probable Cause And A Warrant, Christopher I. Pryby

Michigan Law Review

Under the border search doctrine, courts have upheld the federal government's practice of searching people and their possessions upon entry into or exit from the United States, without any requirement of suspicion, as reasonable under the Fourth Amendment. Since the advent of electronic devices with large storage capacities, courts have grappled with whether this definition of reasonableness continues to apply. So far, courts have consistently characterized “nonforensic” border inspections of electronic devices (for example, paging through photos on a phone) as “routine” searches that, like inspecting luggage brought across international lines, require no suspicion. But there is a circuit split …


Sb 336 - Law Enforcement Officers And Agencies, Richard J. Uberto Jr., Brooke Wilner Dec 2018

Sb 336 - Law Enforcement Officers And Agencies, Richard J. Uberto Jr., Brooke Wilner

Georgia State University Law Review

The Act prohibits data carriers from disclosing to their customers the existence of a subpoena issued for the production of the customers’ records. The Act also allows the Georgia Bureau of Investigation to retain the fingerprints of individuals working in certain professions that require background checks for the duration of employment.


Fourth Amendment Constraints On The Technological Monitoring Of Convicted Sex Offenders, Ben A. Mcjunkin, J. J. Prescott Jul 2018

Fourth Amendment Constraints On The Technological Monitoring Of Convicted Sex Offenders, Ben A. Mcjunkin, J. J. Prescott

Articles

More than forty U.S. states currently track at least some of their convicted sex offenders using GPS devices. Many offenders will be monitored for life. The burdens and expense of living indefinitely under constant technological monitoring have been well documented, but most commentators have assumed that these burdens were of no constitutional moment because states have characterized such surveillance as ‘‘civil’’ in character—and courts have seemed to agree. In 2015, however, the Supreme Court decided in Grady v. North Carolina that attaching a GPS monitoring device to a person was a Fourth Amendment search, notwithstanding the ostensibly civil character of …


Fourth Amendment Fairness, Richard M. Re Jun 2018

Fourth Amendment Fairness, Richard M. Re

Michigan Law Review

Fourth Amendment doctrine is attentive to a wide range of interests, including security, informational privacy, and dignity. How should courts reconcile these competing concerns when deciding which searches and seizures are “unreasonable”? Current doctrine typically answers this question by pointing to interest aggregation: the various interests at stake are added up, placed on figurative scales, and compared, with the goal of promoting overall social welfare. But interest aggregation is disconnected from many settled doctrinal rules and leads to results that are unfair for individuals. The main alternative is originalism; but historical sources themselves suggest that the Fourth Amendment calls for …


The Fourth Amendment Categorical Imperative, David Gray Jan 2017

The Fourth Amendment Categorical Imperative, David Gray

Michigan Law Review Online

The vast majority of current Fourth Amendment doctrine is unfounded, incoherent, and dangerous. The culprit is the Supreme Court’s 1967 decision in 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 …

Search Incident To Probable Cause?: The Intersection Of Rawlings And Knowles, Marissa Perry Jan 2016

Search Incident To Probable Cause?: The Intersection Of Rawlings And Knowles, Marissa Perry

Michigan Law Review

The search incident to arrest exception authorizes an officer to search an arrestee’s person and his or her area of immediate control. This exception is based on two historical justifications: officer safety and evidence preservation. While much of search incident to arrest doctrine is settled, tension exists between two Supreme Court cases, Rawlings v. Kentucky and Knowles v. Iowa, and a crucial question remains unanswered: Must an officer decide to make an arrest prior to commencing a search? In Rawlings, the Supreme Court stated that a search may precede a formal arrest if the arrest follows quickly thereafter. In Knowles, …


Two Wrongs Don't Make A Fourth Amendment Right: Samson Court Errs In Choosing Proper Analytical Framework, Errs In Result, Parolees Lose Fourth Amendment Protection, Rachael A. Lynch Jul 2015

Two Wrongs Don't Make A Fourth Amendment Right: Samson Court Errs In Choosing Proper Analytical Framework, Errs In Result, Parolees Lose Fourth Amendment Protection, Rachael A. Lynch

Akron Law Review

This Note will follow the Fourth Amendment from its origins to its modern application to parolee rights, as evidenced by the Samson Court. Part II focuses on the Fourth Amendment, from the circumstances surrounding its adoption to modern court cases that have applied its tenets to prisoners, probationers, and, finally, parolees. Part III details the Supreme Court’s decision in Samson v. California, including a thorough discussion of the facts that gave rise to the case and lower court decisions. Part IV explores the problems with the Court’s framework and suggests other possible frameworks the Court could have used to come …


Hassle, Jane Bambauer Feb 2015

Hassle, Jane Bambauer

Michigan Law Review

Before police perform a search or seizure, they typically must meet the probable cause or reasonable suspicion standard. Moreover, even if they meet the appropriate standard, their evidence must be individualized to the suspect and cannot rely on purely probabilistic inferences. Scholars and courts have long defended the distinction between individualized and purely probabilistic evidence, but existing theories of individualization fail to articulate principles that are descriptively accurate or normatively desirable. They overlook the only benefit that the individualization requirement can offer: reducing hassle. Hassle measures the chance that an innocent person will experience a search or seizure. Because some …


Supreme Court Jurisprudence Of The Personal In City Of Los Angeles V. Patel, Brian L. Owsley Jan 2015

Supreme Court Jurisprudence Of The Personal In City Of Los Angeles V. Patel, Brian L. Owsley

Michigan Law Review First Impressions

Recently, the Supreme Court issued a 5-4 decision in City of Los Angeles v. Patel striking down a city ordinance that required hotel and motel owners to make their guest registries available to police officers whenever requested to do so. Although the Court’s opinion in Patel simply affirmed the Ninth Circuit’s finding that the ordinance was unconstitutional, the Court could have used Patel to readdress the third-party doctrine, which establishes that “a person has no legitimate expectation of privacy in information he voluntarily turns over to third parties.” Patel provided a vehicle for the Court to do so, particularly because …


No More Shortcuts: Protect Cell Site Location Data With A Warrant Requirement, Lauren E. Babst Jan 2015

No More Shortcuts: Protect Cell Site Location Data With A Warrant Requirement, Lauren E. Babst

Michigan Telecommunications & Technology Law Review

In modern society, the cell phone has become a virtual extension of most Americans, managing all kinds of personal and business matters. Modern cell tower technology allows cell service providers to accumulate a wealth of individuals’ location information while they use their cell phones, and such data is available for law enforcement to obtain without a warrant. This is problematic under the Fourth Amendment, which protects reasonable expectations of privacy. Under the Katz two-prong test, (1) individuals have an actual, subjective expectation of privacy in their cell site location data, and (2) society is prepared to acknowledge that expectation as …


Criminal Innovation And The Warrant Requirement: Reconsidering The Rights-Police Efficiency Trade-Off, Tonja Jacobi, Jonah Kind Jan 2015

Criminal Innovation And The Warrant Requirement: Reconsidering The Rights-Police Efficiency Trade-Off, Tonja Jacobi, Jonah Kind

Faculty Articles

It is routinely assumed that there is a trade-off between police efficiency and the warrant requirement. But existing analysis ignores the interaction between law-enforcement investigative practices and criminal innovation. Narrowing the definition of a search or otherwise limiting the requirement for a warrant gives criminals greater incentive to innovate to avoid detection. With limited resources to develop countermeasures, law enforcement officers will often be just as effective at capturing criminals when facing higher Fourth Amendment hurdles. We provide a game-theoretic model that shows that when law-enforcement investigation and criminal innovation are considered in a dynamic context, the police efficiency rationale …


The Fourth Amendment And Surveillance In A Digital World, Arthur Leavens Jan 2015

The Fourth Amendment And Surveillance In A Digital World, Arthur Leavens

Faculty Scholarship

Technology has transformed government surveillance and opened traditionally private information to official scrutiny. The current privacy-based approach to the Fourth Amendment is unable to cope with the changes. This Article offers a solution to the problems that technological surveillance techniques present. Starting with the introduction of the approach in Katz, the Article reviews the development of privacy-based approach. It then looks at three 21st century Supreme Court cases that grappled with applying the Katz test to advanced technological surveillance techniques: Kyllo, Quon, and Jones. These cases demonstrate the problems that the privacy-based approach creates and the …

The Conversational Consent Search: How “Quick Look” And Other Similar Searches Have Eroded Our Constitutional Rights, Alexander A. Mikhalevsky Jun 2014

The Conversational Consent Search: How “Quick Look” And Other Similar Searches Have Eroded Our Constitutional Rights, Alexander A. Mikhalevsky

Georgia State University Law Review

One area in which law enforcement agencies have stretched constitutional limits concerns the scope of a suspect’s consent to search his or her vehicle. Police forces across the country have tested the limits of consent by asking vague, conversational questions to suspects with the goal of obtaining a suspect’s consent to search, even though that individual may not want to allow the search or may not know that he or she has the right to deny consent.

Conversational phrases like “Can I take a quick look?” or “Can I take a quick look around?” have “emerg[ed] as . . . …


The Court Loses Its Way With The Global Positioning System: United States V. Jones Retreats To The “Classic Trespassory Search”, George M. Dery Iii, Ryan Evaro Dec 2013

The Court Loses Its Way With The Global Positioning System: United States V. Jones Retreats To The “Classic Trespassory Search”, George M. Dery Iii, Ryan Evaro

Michigan Journal of Race and Law

This Article analyzes United States v. Jones, in which the Supreme Court considered whether government placement of a global positioning system (GPS) device on a vehicle to follow a person’s movements constituted a Fourth Amendment “search.” The Jones Court ruled that two distinct definitions existed for a Fourth Amendment “search.” In addition to Katz v. United States’s reasonable-expectation-of-privacy standard, which the Court had used exclusively for over four decades, the Court recognized a second kind of search that it called a “classic trespassory search.” The second kind of search occurs when officials physically trespass or intrude upon a constitutionally protected …


Keeping Up With The Jonses: Making Sure Your History Is Just As Wrong As Everyone Else's, Brian Sawers Feb 2013

Keeping Up With The Jonses: Making Sure Your History Is Just As Wrong As Everyone Else's, Brian Sawers

Michigan Law Review First Impressions

Before Katz v. United States, a search under the Fourth Amendment required a trespass. If there was no trespass on one’s property, then there was no search. In Katz, a 1967 decision, the U.S. Supreme Court abandoned that approach, instead finding a search without a trespass based on the government’s invasion of a “reasonable expectation of privacy.” In Oliver v. United States, the Court found that trespass was not sufficient to create a search. It found no reasonable expectation of privacy in open fields, and thus no search, even though the defendant had erected “No Trespassing” signs around his property …


The Politics Of Privacy In The Criminal Justice System: Information Disclosure, The Fourth Amendment, And Statutory Law Enforcement Exemptions, Erin Murphy Feb 2013

The Politics Of Privacy In The Criminal Justice System: Information Disclosure, The Fourth Amendment, And Statutory Law Enforcement Exemptions, Erin Murphy

Michigan Law Review

When criminal justice scholars think of privacy, they think of the Fourth Amendment. But lately its domain has become far less absolute. The United States Code currently contains over twenty separate statutes that restrict both the acquisition and release of covered information. Largely enacted in the latter part of the twentieth century, these statutes address matters vital to modern existence. They control police access to driver's licenses, educational records, health histories, telephone calls, email messages, and even video rentals. They conform to no common template, but rather enlist a variety of procedural tools to serve as safeguards - ranging from …
