The Tesla Meets The Fourth Amendment, Adam M. Gershowitz

Faculty Publications

Can police search a smart car’s computer without a warrant? Although the Supreme Court banned warrantless searches of cell phones incident to arrest in Riley v. California, the Court left the door open for warrantless searches under other exceptions to the warrant requirement. This is the first article to argue that the Fourth Amendment’s automobile exception currently permits the police to warrantlessly dig into a vehicle’s computer system and extract vast amounts of cell phone data. Just as the police can rip open seats or slash tires to search for drugs under the automobile exception, the police can warrantlessly …

Finally, Part IV will argue that the reform of HIPAA is the best avenue for protecting PHI related to reproductive healthcare.

The Carpenter Test As A Transformation Of Fourth Amendment Law, Matthew Tokson

Utah Law Faculty Scholarship

For over fifty years, the Fourth Amendment’s scope has been largely dictated by the Katz test, which applies the Amendment’s protections only when the government has violated a person’s “reasonable expectation of privacy.” This vague standard is one of the most criticized doctrines in all of American law, and its lack of coherence has made Fourth Amendment search law notoriously confusing. Things have become even more complex following the Supreme Court’s landmark decision in Carpenter v. United States, which has spawned its own alternative test for determining the Fourth Amendment’s scope. The emerging Carpenter test looks to the revealing nature …

The Jones Trespass Doctrine And The Need For A Reasonable Solution To Unreasonable Protection, Geoffrey Corn

Arkansas Law Review

Each day that Houston drivers exit from Interstate 45 to drive to downtown Houston, they pass an odd sight. Nestled within some bushes is an encampment of tents. This encampment is very clearly located on public property adjacent to the interstate highway, and equally clearly populated by homeless individuals. While local police ostensibly tolerate this presence, at least temporarily, the sight frequently evokes an image in my mind of a police search of those tents. This thought is especially prominent on the days I am driving to my law school, South Texas College of Law Houston, to teach my federal …

The Fourth Amendment At Home, Thomas P. Crocker

Indiana Law Journal

A refuge, a domain of personal privacy, and the seat of familial life, the home holds a special place in Fourth Amendment jurisprudence. Supreme Court opinions are replete with statements affirming the special status of the home. Fourth Amendment text places special emphasis on securing protections for the home in addition to persons, papers, and effects against unwarranted government intrusion. Beyond the Fourth Amendment, the home has a unique place within constitutional structure. The home receives privacy protections in addition to sheltering other constitutional values protected by the Due Process Clause and the First Amendment. For example, under the Due …

Saving America’S Privacy Rights: Why Carpenter V. United States Was Wrongly Decided And Why Courts Should Be Promoting Legislative Reform Rather Than Extending Existing Privacy Jurisprudence, David Stone

St. Mary's Law Journal

Privacy rights are under assault, but the Supreme Court’s judicial intervention into the issue, starting with Katz v. United States and leading to the Carpenter v. United States decision has created an inconsistent, piecemeal common law of privacy that forestalls a systematic public policy resolution by Congress and the states. In order to reach a satisfactory and longlasting resolution of the problem consistent with separation of powers principles, the states should consider a constitutional amendment that reduces the danger of pervasive technologyaided surveillance and monitoring, together with a series of statutes addressing each new issue posed by technological change as …

Protecting Online Privacy In The Digital Age: Carpenter V. United States And The Fourth Amendment’S Third-Party Doctrine, Cristina Del Rosso, Carol M. Bast

Catholic University Journal of Law and Technology

The goal of this paper is to examine the future of the third-party doctrine with the proliferation of technology and the online data we are surrounded with daily, specifically after the Supreme Court’s decision in Carpenter v. United States. It is imperative that individuals do not forfeit their Constitutional guarantees for the benefit of living in a technologically advanced society. This requires an understanding of the modern-day functional equivalents of “papers” and “effects.”

Looking to the future, this paper contemplates solutions on how to move forward in this technology era by scrutinizing the relevancy of the third-party doctrine due …

Cell Phones Are Orwell's Telescreen: The Need For Fourth Amendment Protection In Real-Time Cell Phone Location Information, Matthew Devoy Jones

Cleveland State Law Review

Courts are divided as to whether law enforcement can collect cell phone location information in real-time without a warrant under the Fourth Amendment. This Article argues that Carpenter v. United States requires a warrant under the Fourth Amendment prior to law enforcement’s collection of real-time cell phone location information. Courts that have required a warrant prior to the government’s collection of real-time cell phone location information have considered the length of surveillance. This should not be a factor. The growing prevalence and usage of cell phones and cell phone technology, the original intent of the Fourth Amendment, and United States …

Nowhere To Run, Nowhere To Hide.* Applying The Fourth Amendment To Connected Cars In The Internet-Of-Things Era, Gregory C. Brown, Jr.

Journal of Civil Rights and Economic Development

(Excerpt)

Part I of this Note will briefly discuss the key components of a Connected Car, identify who collects the data from the Car, and examine the various uses for the data. Part I also explores whether Car owners consent to the collection of their Car’s data. Part II-A will trace the historical development of the automobile exception to the Fourth Amendment, which generally permits law-enforcement officers to conduct a warrantless search of a vehicle. Part II-B will discuss how the Supreme Court has applied the Fourth Amendment to pre-Internet technologies. Part II-C will discuss two recent Fourth Amendment Supreme …

Functional Equivalence And Residual Rights Post-Carpenter: Framing A Test Consistent With Precedent And Original Meaning, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

The Carpenter Court held that warrantless access to seven or more days of cell site location information (CSLI) constitutes a violation of the reasonable expectation of privacy that individuals have in the whole of their physical movements. But the grounds on which the Court drew a line characterize all sorts of digital records—including those at issue in Miller and Smith, belying the majority’s claim that the decision leaves third-party doctrine intact. Instead of avoiding Katz’s pitfalls, moreover, the Court emphasized voluntary assumption of risk, doubling down on the subjective nature of judicial determination. The decision will likely lead to …

Property, Persons, And Institutionalized Police Interdiction In Byrd V. United States, Eric J. Miller

Loyola of Los Angeles Law Review

During a fairly routine traffic stop of a motorist driving a rental car, two State Troopers in Harrisburg, Pennsylvania, discovered that the driver, Terrence Byrd, was not the listed renter. The Court ruled that Byrd nonetheless retained a Fourth Amendment right to object to the search. The Court did not address, however, why the Troopers stopped Byrd in the first place. A close examination of the case filings reveal suggests that Byrd was stopped on the basis of his race. The racial feature ofthe stop is obscured by the Court’s current property-basedinterpretation of the Fourth Amendment’s right to privacy.

Although …

Knowledge And Fourth Amendment Privacy, Matthew Tokson

Northwestern University Law Review

This Article examines the central role that knowledge plays in determining the Fourth Amendment’s scope. What people know about surveillance practices or new technologies often shapes the “reasonable expectations of privacy” that define the Fourth Amendment’s boundaries. From early decisions dealing with automobile searches to recent cases involving advanced information technologies, courts have relied on assessments of knowledge in a wide variety of Fourth Amendment contexts. Yet the analysis of knowledge in Fourth Amendment law is rarely if ever studied on its own.

This Article fills that gap. It starts by identifying the characteristics of Fourth Amendment knowledge. It finds, …

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 …

Voluntary Disclosure Of Information As A Proposed Standard For The Fourth Amendment's Third-Party Doctrine, Margaret E. Twomey

Michigan Telecommunications & Technology Law Review

The third-party doctrine is a long-standing tenant of Fourth Amendment law that allows law enforcement officers to utilize information that was released to a third party without the probable cause required for a traditional search warrant. This has allowed law enforcement agents to use confidential informants, undercover agents, and access bank records of suspected criminals. However, in a digital age where exponentially more information is shared with Internet Service Providers, e-mail hosts, and social media “friends,” the traditional thirdparty doctrine ideas allow law enforcement officers access to a cache of personal information and data with a standard below probable cause. …

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

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 …

Justice Scalia's Fourth Amendment: Text, Context, Clarity, And Occasional Faint-Hearted Originalism, Timothy C. Macdonnell

Scholarly Articles

Since joining the United States Supreme Court in 1986, Justice Scalia has been a prominent voice on the Fourth Amendment, having written twenty majority opinions, twelve concurrences, and six dissents on the topic. Under his pen, the Court has altered its test for determining when the Fourth Amendment should apply; provided a vision to address technology's encroachment on privacy; and articulated the standard for determining whether government officials are entitled to qualified immunity in civil suits involving alleged Fourth Amendment violations. In most of Justice Scalia's opinions, he has championed an originalist/textualist theory of constitutional interpretation. Based on that theory, …

Robots In The Home: What Will We Have Agreed To?, Margot E. Kaminski

Publications

A new technology can expose the cracks in legal doctrine. Sometimes a technology resists analogy. Sometimes, through analogies, it reveals inconsistencies in the law, or basic flaws in framing, or in the fit between different parts of the legal system. This Essay addresses robots in the home, and what they reveal about U.S. privacy law. Household robots might not themselves uproot U.S. privacy law, but they will reveal its inconsistencies, and show where it is most likely to fracture. Just as drones are serving as a legislative “privacy catalyst” — encouraging the enactment of new privacy laws as people realize …

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 …

Bringing Clarity To Administrative Search Doctrine: Distinguishing Dragnets From Special Subpopulation Searches, Eve Brensike Primus

Articles

Anyone who has been stopped at a sobriety checkpoint, screened at an international border, scanned by a metal detector at an airport or government building, or drug tested for public employment has been subjected to an administrative search or seizure. Searches of public school students, government employees, and probationers are characterized as administrative, as are business inspections and-increasingly-wiretaps and other searches used in the gathering of national security intelligence. In other words, the government conducts thousands of administrative searches every day. None of these searches requires either probable cause or a search warrant. Instead, courts evaluating administrative searches need only …

How United States V. Jones Can Restore Our Faith In The Fourth Amendment, Erica Goldberg

Michigan Law Review First Impressions

United States v. Jones, issued in January of this year, is a landmark case that has the potential to restore a property-based interpretation of the Fourth Amendment to prominence. In 1967, the Supreme Court abandoned its previous Fourth Amendment framework, which had viewed the prohibition on unreasonable searches in light of property and trespass laws, and replaced it with a rule protecting the public’s reasonable expectations of privacy. Although the Court may have intended this reasonable expectations test to provide more protection than a test rooted in property law, the new test in fact made the Justices’ subjective views about …

Disentangling Administrative Searches, Eve Brensike Primus

Articles

Everyone who has been screened at an international border, scanned by an airport metal detector, or drug tested for public employment has been subjected to an administrative search. Since September 11th, the government has increasingly invoked the administrative search exception to justify more checkpoints, unprecedented subway searches, and extensive wiretaps. As science and technology advance, the frequency and scope of administrative searches will only expand. Formulating the boundaries and requirements of administrative search doctrine is therefore a matter of great importance. Yet the rules governing administrative searches are notoriously unclear. This Article seeks to refocus attention on administrative searches and …

The Anatomy Of A Search: Intrusiveness And The Fourth Amendment, Renee Mcdonald Hutchins

Journal Articles

For more than two months beginning in late December of 2005, police officers in New York State continuously monitored the location and movements of Scott Weaver's van using a surreptitiously attached global positioning system ("GPS") device, known as a "Qball."' The reason Weaver was targeted for police surveillance has never been disclosed. 2 In addition, law enforcement made no attempt to justify the heightened scrutiny of Weaver by seeking the pre-authorization of a warrant from a neutral magistrate.3 Rather, for sixty-five days, the police subjected Weaver to intense surveillance without oversight, interruption, or explanation. 4 More than a year after …

Garbage Pails And Puppy Dog Tails: Is That What Katz Is Made Of?, Aya Gruber

Publications

This Article takes the opportunity of the fortieth anniversary of Katz v. U.S. to assess whether the revolutionary case's potential to provide broad and flexible privacy protection to individuals has been realized. Answering this question in a circumspect way, the Article pinpoints the language in Katz that was its eventual undoing and demonstrates how the Katz test has been plagued by two principle problems that have often rendered it more harmful to than protective of privacy. The manipulation problem describes the tendency of conservative courts to define reasonable expectations of privacy as lower than the expectations society actually entertains. The …

Tied Up In Knotts? Gps And The Fourth Amendment, Renee Mcdonald Hutchins

Journal Articles

Judicial and scholarly assessment of emerging technology seems poised to drive the Fourth Amendment down one of three paths. The first would simply relegate the amendment to a footnote in history books by limiting its reach to harms that the framers specifically envisioned. A modified version of this first approach would dispense with expansive constitutional notions of privacy and replace them with legislative fixes. A third path offers the amendment continued vitality but requires the U.S. Supreme Court to overhaul its Fourth Amendment analysis. Fortunately, a fourth alternative is available to cabin emerging technologies within the existing doctrinal framework. Analysis …

The Fourth Amendment In The Hallway: Do Tenants Have A Constitutionally Protected Privacy Interest In The Locked Common Areas Of Their Apartment Buildings?, Sean M. Lewis

Michigan Law Review

One afternoon, a police officer spots a man driving a Cadillac through a run·down neighborhood. His interest piqued, the officer decides to follow the vehicle. The Cadillac soon comes to rest in front of an apartment building, and the driver, Jimmy Barrios-Moriera, removes a shopping bag from the trunk and enters the building. The moment Barrios-Moriera disappears within the doorway, the officer sprints after him because he knows that the door to the apartment building will automatically lock when it closes. He manages to catch the door just in time and rushes in. Barrios-Moriera is already halfway up a flight …

We Can Do This The Easy Way Or The Hard Way: The Use Of Deceit To Induce Consent Searches, Rebecca Strauss

Michigan Law Review

In October of 1995, Aaron Salvo was studying and living at Ashland College. College officials informed local FBI agents that they suspected Salvo of possible child molestation and related conduct based on incriminating electronic mail. FBI agents approached Salvo at his dormitory, asked to speak with him in private about the suspicious mail, and suggested they speak in Salvo's dorm room. Salvo agreed to speak with the officers, but declined to do so in his room because his roommate was there, and he did not want to get anyone else involved in the embarrassing nature of the upcoming conversation. Salvo …

Recovering The Original Fourth Amendment, Thomas Y. Davies

Michigan Law Review

Claims regarding the original or intended meaning of constitutional texts are commonplace in constitutional argument and analysis. All such claims are subject to an implicit validity criterion - only historically authentic assertions should matter. The rub is that the original meaning commonly attributed to a constitutional text may not be authentic. The historical Fourth Amendment is a case in point. If American judges, lawyers, or law teachers were asked what the Framers intended when they adopted the Fourth Amendment, they would likely answer that the Framers intended that all searches and seizures conducted by government officers must be reasonable given …
