Escaping Circularity: The Fourth Amendment And Property Law, João Marinotti

Articles by Maurer Faculty

The Supreme Court’s “reasonable expectation of privacy” test under the Fourth Amendment has often been criticized as circular, and hence subjective and unpredictable. The Court is presumed to base its decisions on society’s expectations of privacy, while society’s expectations of privacy are themselves presumed to be based on the Court’s judgements. As a solution to this problem, property law has been repeatedly propounded as an allegedly independent, autonomous area of law from which the Supreme Court can glean reasonable expectations of privacy without falling back into tautological reasoning.

Such an approach presupposes that property law is not itself circular. If …

Fourth Amendment Limits On Extensive Quarantine Surveillance, Benjamin Wolters

Duke Journal of Constitutional Law & Public Policy Sidebar

The devastation wreaked by the COVID-19 pandemic spurred innovations in technology and public policy. Many countries rushed to implement extensive quarantines, and some introduced disease surveillance, including location tracking to enforce quarantines. Though the United States has never implemented high-tech quarantine surveillance, such technology will certainly be available for the next disease outbreak.

Absent significant doctrinal change, the Fourth Amendment likely bars some, but not all, forms of quarantine surveillance. Quarantine surveillance probably constitutes a Fourth Amendment “search” that generally must be backed by probable cause. This probable cause requirement, and its subcomponent of individualized suspicion, likely applies differently to …

Note: The "Border" Of Constitutional Electronic Privacy Rights: Electronic Searches And Seizures At The United States' Territorial Limits, Ryan Garippo

Notre Dame Journal on Emerging Technologies

In the recent challenge brought before the First Circuit, the court was not required to directly answer what level of particularized suspicion is required for a forensic search. Although, its holding is consistent with the jurisprudence set forth by both the Fourth and Eleventh Circuits. Furthermore, it is important to note that there have been legal challenges brought on this issue in the Fifth, Seventh, and Tenth Circuits. However, in each of these cases, the court chose not to decide the constitutional question because it was not outcome determinative for the litigants in question. This disagreement between the federal circuit …

Cloudy With A Chance Of Government Intrusion: The Third-Party Doctrine In The 21st Century, Steven Arango

Catholic University Law Review

Technology may be created by humans, but we are dependent on it. Look around you: what technology is near you as you read this abstract? An iPhone? A laptop? Perhaps even an Amazon Echo. What do all these devices have in common? They store data in the cloud. And this data can contain some of our most sensitive information, such as business records or medical documents.

Even if you manage this cloud storage account, the government may be able to search your data without a warrant. Federal law provides little protection for cloud stored data. And the Fourth Amendment may …

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 …

Inescapable Surveillance, Matthew Tokson

Utah Law Faculty Scholarship

Until recently, Supreme Court precedent dictated that a person waives their Fourth Amendment rights in information they disclose to another party. The Court reshaped this doctrine in Carpenter v. United States, establishing that the Fourth Amendment protects cell phone location data even though it is revealed to others. The Court emphasized that consumers had little choice but to disclose their data, because cell phone use is virtually inescapable in modern society.

In the wake of Carpenter, many scholars and lower courts have endorsed inescapability as an important factor for determining Fourth Amendment rights. Under this approach, surveillance that people cannot …

Preservation Requests And The Fourth Amendment, Armin Tadayon

Seattle University Law Review

Every day, Facebook, Twitter, Google, Amazon, ridesharing companies, and numerous other service providers copy users’ account information upon receiving a preservation request from the government. These requests are authorized under a relatively obscure subsection of the Stored Communications Act (SCA). The SCA is the federal statute that governs the disclosure of communications stored by third party service providers. Section 2703(f) of this statute authorizes the use of “f” or “preservation” letters, which enable the government to request that a service provider “take all necessary steps to preserve records and other evidence in its possession” while investigators seek valid legal process. …

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 …

Adapting U.S. Electronic Surveillance Laws, Policies, And Practices To Reflect Impending Technological Developments, Eric Manpearl

Catholic University Law Review

Intelligence collection must always evolve to meet technological developments. While the collection programs under Section 702 of the FISA Amendments Act of 2008 have produced a great deal of valuable intelligence over the last decade, the United States must begin to think about foreseeable technological developments and strategically consider how to conduct signals intelligence (SIGINT) collection in the future.

This Article identifies four technological trends that could significantly impact the way the United States conducts SIGINT. Individuals now have access to sophisticated technologies that formerly only governments seemed capable of creating, and this decentralization of capabilities will likely only increase …

A Third-Party Doctrine For Digital Metadata, H. Brian Holland

Faculty Scholarship

For more than four decades, the third-party doctrine was understood as a bright-line, categorical rule: there is no legitimate privacy interest in any data that is voluntarily disclosed or conveyed to a third party. But this simple rule has dramatic effects in a world of ubiquitous networked computing, mobile technologies, and the commodification of information. The digital devices that facilitate our daily participation in modern society are connected through automated infrastructures that are designed to generate vast quantities of data, nearly all of which is captured, utilized, and stored by third-party service providers. Under a plain reading of the third-party …

Hash It Out: Fourth Amendment Protection Of Electronically Stored Child Exploitation, Rebekah A. Branham

Akron Law Review

Few courts have addressed whether ISP’s use of hash-based evaluation violates an individual’s Fourth Amendment rights. In 2018, the Fifth Circuit was presented with this issue in United States v. Reddick. The defendant is Reddick uploaded files to the cloud-sharing server Microsoft SkyDrive. Thereafter PhotoDNA, a computer software program that uses hashing, automatically reviewed the hash values of those files and compared them against its database of known child pornography hash values. PhotoDNA detected a hash value match between the defendant’s photos and the database. It then created a “CyberTip,” sending the files and users information to the NCMEC. …

Dna Is Different: An Exploration Of The Current Inadequacies Of Genetic Privacy Protection In Recreational Dna Databases, Jamie M. Zeevi

St. John's Law Review

(Excerpt)

Part I of this Note discusses the fundamental science behind DNA and defines and explains the process of familial DNA searching. Part I also discusses how Carpenter v. United States provides a framework to begin thinking about the unique nature of DNA and privacy implications for its use, and why the revealing nature of this type of data warrants protection. Part II of this Note delves into the lack of constitutional and statutory protections for DNA in recreational DNA databases. First, Part II explains that traditional Fourth Amendment concepts, like search warrants, probable cause, reasonable expectation of privacy, third-party …

St. John's Law Review

(Excerpt)

This Review discusses two timely and insightful books examining the changing relationship between privacy and the Fourth Amendment in the digital era. Part I discusses the tensions between the need to protect privacy rights and the slowly evolving legal landscape during a time of rapidly changing technology, to introduce David Gray’s The Fourth Amendment in an Age of Surveillance. His book explains how the Fourth Amendment, though embattled, can have a prominent role in twenty-first century discussions of privacy, technology, and surveillance. Gray’s analysis is engaged to broaden the conversation about Stingray technology. This section analyzes a sampling of …

Unlimited Data Search Plan: Warrantless Border Search Of Mobile Device Data Likely Unconstitutional For Violating The Fundamental Right To Informational Privacy, Atanu Das

St. John's Law Review

(Excerpt)

Part I of this Article discusses a case in which a United States citizen was subject to an unconstitutional warrantless border search of his mobile device data. Part II explains the history and current state of Supreme Court jurisprudence of the border search exception doctrine. Part III explains the way in which Supreme Court jurisprudence finds the right to informational privacy for mobile device data to be a fundamental right. Part IV discusses the reluctance of some legal commentators to find that a governmental intrusion on the right to informational privacy is subject to strict scrutiny. Part V finds …

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 …

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 …

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 …

The Normative Fourth Amendment, Matthew Tokson

Utah Law Faculty Scholarship

For decades, courts have used a “reasonable expectation of privacy” standard to determine whether a government action is a Fourth Amendment search. Scholars have convincingly argued that this test is incoherent, arbitrary, and incapable of protecting privacy against modern forms of surveillance. Yet few alternatives have been proposed, and those alternatives pose many of the same problems as the current standard.

This Article offers a new theoretical approach for determining the scope of the Fourth Amendment. It develops a normative model of Fourth Amendment searches, one that explicitly addresses the balance between law enforcement effectiveness and citizens’ interests inherent in …

Mission Creep And Wiretap Act 'Super Warrants': A Cautionary Tale, Jennifer S. Granick, Patrick Toomey, Naomi Gilens, Daniel Yadron Jr.

Loyola of Los Angeles Law Review

Congress enacted the Wiretap Act in 1968 in an effort to combat organized crime while safeguarding the privacy of innocent Americans. However, the Act instead served to legitimize wiretapping, and its privacy protections have eroded over time. As a result, there has been a significant increase in wiretapping in the decades since the Act’s passage. As technology evolves, the Wiretap Act does less to protect Americans’ private communications from government interception. Nevertheless, policy makers see the Wiretap Act, with its “super-warrant” procedures, as the gold standard for statutory privacy protection. To the contrary, when considering how to regulate new and …

The Public Information Fallacy, Woodrow Hartzog

Faculty Scholarship

The concept of privacy in “public” information or acts is a perennial topic for debate. It has given privacy law fits. People struggle to reconcile the notion of protecting information that has been made public with traditional accounts of privacy. As a result, successfully labeling information as public often functions as a permission slip for surveillance and personal data practices. It has also given birth to a significant and persistent misconception — that public information is an established and objective concept.

In this article, I argue that the “no privacy in public” justification is misguided because nobody knows what “public” …

The Value Of Deviance: Understanding Contextual Privacy, Timothy Casey

Faculty Scholarship

Recent decisions by the Supreme Court in Carpenter v. United States and the Illinois Supreme Court in Rosenbach v. Six Flags Entertainment Corporation signal a shift in the traditional understanding of what exactly is protected by a privacy interest. Carpenter distinguished between a police officer’s observation of a suspect’s location and a perpetual catalogue of a person’s movements obtained through cell site location information (CSLI). The pervasive and vast quantity of information from CSLI exposed a protected privacy interest. In Rosenbach, the Illinois Supreme Court found the unique and personal quality of biometric information meant that consent and disclosure requirements …

Protecting Online Privacy In The Digital Age: Carpenter V. United States And The Fourth Amendment's Third-Party Doctrine, Cristina Del Rosso

Honors Undergraduate Theses

The intent of this thesis 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 United States Supreme Court's decision in Carpenter v. United States. In order to better understand the Supreme Court's reasoning in that case, this thesis will review the history of the third-party doctrine and its roots in United States v. Miller and Smith v. Maryland. A review of Fourth Amendment history and jurisprudence is also crucial to this thesis, as it is imperative that individuals do not forfeit …

Warrantless Searches Of Electronic Devices At U.S. Borders: Securing The Nation Or Violating Digital Liberty?, Ahad Khilji

Catholic University Journal of Law and Technology

The steady increase of U.S. citizens traveling with smart phones and other electronic devices has been met with the rise of searches and seizures by CBP officers at U.S borders. Although only less than 0.1% of all travelers may actually be subjected to a search while entering the United States, when comparing the statistics between a six month period in 2016 with the same period in 2017, electronic device searches have almost doubled from 8,383 to 14,993. Approximately one million travelers to the U.S. are inspected by the CBP every day. Out of this population, nearly 2,500 electronic devices are …

The Exclusionary Rule In The Age Of Blue Data, Andrew Ferguson

Scholarly Articles in Law Reviews & Journals

In Herring v. United States, Chief Justice John Roberts reframed the Supreme Court’s understanding of the exclusionary rule: “As laid out in our cases, the exclusionary rule serves to deter deliberate, reckless, or grossly negligent conduct, or in some circumstances recurring or systemic negligence.” The open question remains: how can defendants demonstrate sufficient recurring or systemic negligence to warrant exclusion? The Supreme Court has never answered the question, although the absence of systemic or recurring problems has figured prominently in two recent exclusionary rule decisions. Without the ability to document recurring failures, or patterns of police misconduct, courts can dismiss …
