The Post-Dobbs Reality: Privacy Expectations For Period-Tracking Apps In Criminal Abortion Prosecutions, Sophie L. Nelson

Pepperdine Law Review

The Supreme Court’s decision to overturn Roe v. Wade and Planned Parenthood v. Casey in June 2022 was met with waves of both support and criticism throughout the United States. Several states immediately implemented or began drafting trigger laws that criminalize seeking and providing an abortion. These laws prompted several period-tracking app companies to encrypt their users’ data to make it more difficult for the government to access period- and pregnancy-related information for criminal investigations. This Comment explores whether the Fourth Amendment and U.S. privacy statutes protect users of period-tracking apps from government surveillance. More specifically, this Comment argues that …

Pretrial Commitment And The Fourth Amendment, Laurent Sacharoff

Notre Dame Law Review

Today, the Fourth Amendment Warrant Clause governs arrest warrants and search warrants only. But in the founding era, the Warrant Clause governed a third type of warrant: the “warrant of commitment.” Judges issued these warrants to jail defendants pending trial. This Article argues that the Fourth Amendment Warrant Clause, with its oath and probable cause standard, should be understood today to apply to this third type of warrant. That means the Warrant Clause would govern any initial appearance where a judge first commits a defendant—a process that currently falls far short of fulfilling its constitutional and historical function. History supports …

Arrests: Legal And Illegal, Daniel Yeager

Georgia State University Law Review

The Fourth Amendment prohibits unreasonable searches and seizures. An arrest—manifesting a police intention to transport a suspect to the stationhouse for booking, fingerprinting, and photographing—is a mode of seizure. Because arrests are so intrusive, they require roughly a fifty percent chance that an arrestable offense has occurred. Because nonarrest seizures (aka Terry stops), though no “petty indignity,” are less intrusive than arrests, they require roughly just a twenty-five percent chance that crime is afoot.

Any arrest not supported by probable cause is illegal. It would therefore seem to follow that any arrest supported by probable cause is legal. But it …

The Automated Fourth Amendment, Maneka Sinha

Emory Law Journal

Courts routinely defer to police officer judgments in reasonable suspicion and probable cause determinations. Increasingly, though, police officers outsource these threshold judgments to new forms of technology that purport to predict and detect crime and identify those responsible. These policing technologies automate core police determinations about whether crime is occurring and who is responsible.

Criminal procedure doctrine has failed to insist on some level of scrutiny of—or skepticism about—the reliability of this technology. Through an original study analyzing numerous state and federal court opinions, this Article exposes the implications of law enforcement’s reliance on these practices given the weighty interests …

Community Caretaking Exception Saves Lives . . . The Supreme Court Disagrees, Gabriella Lorenzo

Touro Law Review

As many are aware, the Fourth Amendment protects the people against unreasonable searches and seizures. A warrant is necessary for said activities. While there are a few exceptions to the warrant requirement, the Supreme Court recently held that the community caretaking exception does not extend to the home. Extending this exception to the home would allow police officers to enter and engage in functions that are unrelated to the investigation of a crime. Essentially, this exception would allow police to aid individuals and prevent serious, dangerous situations to protect the community. This Note discusses why the Supreme Court erred in …

The Unconstitutional Conditions Vacuum In Criminal Procedure, Kay L. Levine, Jonathan R. Nash, Robert A. Schapiro

Faculty Articles

For more than a century, the Supreme Court has applied the unconstitutional conditions doctrine in many contexts, scrutinizing government efforts to condition the tradeoff of rights for benefits with regard to speech, funding, and takings, among others. The Court has declined, however, to invoke the doctrine in the area of criminal procedure, where people accused of crime are often asked to—and often do—surrender their constitutional rights under the Fourth, Fifth, and Sixth Amendments in return for some benefit. Despite its insistence that the unconstitutional conditions doctrine applies broadly across the Bill of Rights, the Court’s jurisprudence demonstrates that the doctrine …

A Loophole In The Fourth Amendment: The Government's Unregulated Purchase Of Intimate Health Data, Rhea Bhatia

Washington Law Review Online

Companies use everyday applications and personal devices to collect deeply personal information about a user’s body and health. While this “intimate health data” includes seemingly innocuous information about fitness activities and basic vitals, it also includes extremely private information about the user’s health, such as chronic conditions and reproductive health. However, consumers have no established rights over the intimate health data shared on their devices. Believing that these technologies are created for their benefit, consumers hand over the most intimate aspects of their lives through health-related applications relying on the promise that their data will remain private. Today, the intimate …

Breaking The Fourth's Wall: The Implications Of Remote Education For Students' Fourth Amendment Rights, Sallie Hatfield

Vanderbilt Journal of Entertainment & Technology Law

As the COVID-19 pandemic forced both public K-12 and higher education institutions to transition to exclusively provide remote education, students’ homes and personal lives were exposed to the government like never before. Zoom classes and remote proctoring were suddenly the norm. Students and their families scrambled to create appropriate offices and classroom spaces in their homes, and many awkward and invasive scenarios soon followed. While many may have been harmlessly captured on camera, like classes that witness a student’s family eating lunch in the background or a dog on the couch, even these harmless instances have insidious implications for the …

You Can’T Teach Old Katz New Tricks: It’S Time To Revitalize The Fourth Amendment, Jeremy Connell

University of Miami Law Review

For over half a century, the Court’s decision in Katz v. United States has been the lodestar for applying the Fourth Amendment. The Katz test has produced a litany of confusing and irreconcilable decisions in which the Court has carved exceptions into the doctrine and then carved exceptions into the exceptions. These decisions often leave lower courts with minimal guidance on how to apply the framework to new sets of facts and leave legal scholars and commenters befuddled and frustrated with the Court’s explanations for the rulings. The Court’s decision in Carpenter v. United States represents the apex of Katz’s …

Private Police Regulation And The Exclusionary Remedy: How Washington Can Eliminate The Public/Private Distinction, Jared Rothenberg

Washington Law Review

Private security forces such as campus police, security guards, loss prevention officers, and the like are not state actors covered by the Fourth Amendment’s prohibition against unreasonable searches and seizures nor the Fifth Amendment’s Miranda protections. As members of the umbrella category of “private police,” these private law enforcement agents often obtain evidence, detain individuals, and elicit confessions in a manner that government actors cannot, which can then be lawfully turned over to the government. Though the same statutory law governing private citizens (assault, false imprisonment, trespass, etc.) also regulates private police conduct, private police conduct is not bound by …

Wrong Search At The Wrong Time: Keyword Search Warrants And The Fourth Amendment, Nicole Chan

Articles

This Note will advocate for the view that when presented with the issue, state and federal courts should establish that keyword search warrants are unconstitutional because they violate the Fourth Amendment. Keyword search warrants cannot meet the Fourth Amendment’s requirements of probable cause and particularity because the subjects of the search cannot be identified until after the search is completed. These warrants are unnecessary and have the potential of implicating millions of internet users who have no connection to a crime. This Note will contend that individuals have a reasonable expectation of privacy in their search history data, and that …

Reasonable In Time, Unreasonable In Scope: Maximizing Fourth Amendment Protections Under Rodriguez V. United States, Thomas Heiden

Washington Law Review

In Rodriguez v. United States, the Supreme Court held that a law enforcement officer may not conduct a drug dog sniff after the completion of a routine traffic stop because doing so extends the stop without reasonable suspicion in violation of the Fourth Amendment’s prohibition on unreasonable seizures. Tracing the background of Rodriguez from the Supreme Court’s landmark decision in Terry v. Ohio, this Comment argues that Rodriguez is best understood as a reaction to the continued erosion of Fourth Amendment protections in the investigative stop context. Based on that understanding, this Comment argues for a strict reading of Rodriguez, …

Administrative Regulation Of Programmatic Policing: Why "Leaders Of A Beautiful Struggle" Is Both Right And Wrong, Christopher Slobogin

Vanderbilt Law School Faculty Publications

In Leaders of a Beautiful Struggle v. Baltimore Police Department, the Fourth Circuit Court of Appeals held that Aerial Investigation Research (AIR), Baltimore's aerial surveillance program, violated the Fourth Amendment because it was not authorized by a warrant. AIR was constitutionaly problematic, but not for the reason given by the Fourth Circuit. AIR, like many other technologically-enhanced policing programs that rely on closed-circuit television (CCTV), automated license plate readers and the like, involves the collection and retention of information about huge numbers ofpeople. Because individualized suspicion does not exist with respect to any of these people's information, an individual-specific warrant …

The United States Should Take A Page Out Of Canadian Law When It Comes To Privacy, Genetic And Otherwise, Ashley Rahaim

University of Miami Inter-American Law Review

Genetic information is intimate and telling data warranting privacy in public and private realms. The privacy protections offered in the United States and Canada vastly differ when it comes to genetic privacy. Search and seizure law mirrors the privacy gap in the countries, as well as their treatment of DNA database information.

This note explores the foreshadowing of the creation of genetic privacy laws and their varying levels of protection based on the way private information was treated by state actors through search and seizure caselaw, the creation of legal precedent, and the treatment of intimate personal data in the …

Per Curiam Signals In The Supreme Court's Shadow Docket, Zina Makar

Washington Law Review

Lower courts and litigants depend a great deal on the Supreme Court to articulate and communicate signals regarding how to interpret existing doctrine. Signals are at their strongest and most reliable when they originate from the Court’s merits docket. More recently, the Court has been increasingly relying on its orders docket—colloquially referred to as its “shadow docket”—to communicate with lower courts by summarily reversing and correcting errors in interpretation without briefing or oral argument.

Over the past decade the Roberts Court has granted certiorari to summarily reverse a growing number of qualified immunity cases, issuing over a dozen unsigned per …

The Ambiguity Of Probable Cause And Its Contentious Application By Police, Dave Sainte-Luce

College Honors Program

It is well documented how our country’s Criminal Justice System has a history of targeting people of color. A lot of this contention is derived from police officers’ behavior when interacting with individuals, yet officers only act upon the laws and legal policies that grant them authority, including probable cause. My thesis addresses the question, how does the fluid and ambiguous nature of probable cause leave the door open for officers to disproportionately target people of color in the United States? While focusing on vehicle, person, and property searches, I first define probable cause, building an understanding of exactly what …

A New Test For The New Crime Exception, Colin Miller

Utah Law Review

The new crime exception to the Fourth Amendment exclusionary rule allows prosecutors to introduce evidence connected to new crimes committed by defendants who were illegally detained and/or questioned. Unfortunately, as illustrated in this Article, courts largely have applied this new crime exception without any analytical framework or regard for the severity of the initial police misconduct or the defendant’s response. Moreover, courts have begun applying the new crime exception to crimes such as giving a fake name in response to an un-Mirandized interrogation following a lawful arrest.

By doing so, courts have allowed the new crime exception to swallow two …

Privacy And Property: Constitutional Concerns Of Dna Dragnet Testing, E. Wyatt Jones

Honors Projects

DNA dragnets have attracted both public and scholarly criticisms that have yet to be resolved by the Courts. This review will introduce a modern understanding of DNA analysis, a complete introduction to past and present Fourth and Fourteenth Amendment jurisprudence, and existing suggestions concerning similar issues in legal scholarship. Considering these contexts, this review concludes that a focus on privacy and property at once, with a particular sensitivity to the inseverable relationship between the two interests, is Constitutionally consistent with precedent and the most workable means of answering the question at hand.

Gone Fishing: Casting A Wide Net Using Geofence Warrants, Ryan Tursi

Washington Law Review

Technology companies across the country receive requests from law enforcement agencies for cell phone location information near the scenes of crimes. These requests rely on the traditional warrant process and are known as geofence warrants, or reverse location search warrants. By obtaining location information, law enforcement can identify potential suspects or persons of interest who were near the scene of a crime when they have no leads. But the use of this investigative technique is controversial, as it threatens to intrude upon the privacy of innocent bystanders who had the misfortune of being nearby when the crime took place. Innocent …

Searches Without Suspicion: Avoiding A Four Million Person Underclass, Tonja Jacobi, Addie Maguire

Faculty Articles

In Samson v. California, the Supreme Court upheld warrantless, suspicionless searches for parolees. That determination was controversial both because suspicionless searches are, by definition, anathema to the Fourth Amendment, and because they arguably undermine parolees’ rehabilitation. Less attention has been given to the fact that the implications of the case were not limited to parolees. The opinion in Samson included half a sentence of dicta that seemingly swept probationers into its analysis, implicating the rights of millions of additional people in the United States. Not only is analogizing parolees and probationers not logically sound because the two groups differ …

When Dirty Data Leads To Dirty Policing, Madison Blevins

Law Student Publications

"On May 25th, 2020, George Floyd was tragically killed by police officers in Minneapolis. While George Floyd’s death was the shock that catapulted the Black Lives Matter (“BLM”) movement to the center of international attention, it was also just the tip of the iceberg. Floyd’s death was not the first death of a black person at the hands of the police, nor would it be the last. “A black person is killed by a police officer in America at a rate of more than one [person] every other day.” These repeated incidents across the country have ignited a mass movement …

On Warrants & Waiting: Electronic Warrants & The Fourth Amendment, Tracy Hresko Pearl

Indiana Law Journal

Police use of electronic warrant (“e-warrant”) technology has increased significantly in recent years. E-warrant technology allows law enforcement to submit, and magistrate judges to review and approve, warrant applications on computers, smartphones, and tablets, often without any direct communication. Police officers report that they favor e-warrants over their traditional, paper counterparts because they save officers a significant amount of time in applying for warrants by eliminating the need to appear in-person before a magistrate. Legal scholars have almost uniformly praised e-warrant technology as well, arguing that use of these systems will increase the number of warrants issued throughout the United …

Is There A Fundamental Right To Privacy When An Educational Institution Requires A Student To Disclose Proof Of His Or Her Vaccination Status?, Mary D. Fatscher

Touro Law Review

In 2020, the coronavirus disease (“COVID-19”) dominated the world. Although the public has progressively become more informed about the disease and how to safeguard itself, challenges persist as there is still much unknown. Aside from wearing masks, social distancing, and despite its undetermined consequences, the COVID-19 vaccination has emerged as a primary solution to substantially reducing the incidence and severity of the virus in our country. Many COVID-19 vaccine mandates were initiated once three pharmaceutical and biotechnology companies including Pfizer-BioNTech, Moderna, and Johnson & Johnson received Emergency Use Authorization from the Food and Drug Administration (“FDA”).

Evolving Privacy Protections For Emerging Machine Learning Data Under Carpenter V. United States, Emily Nicolella

FIU Law Review

The Fourth Amendment’s third-party doctrine eliminates an individual’s reasonable expectation of privacy in information they willingly turn over to third parties. Government scrutiny of this information is not considered a search under the Fourth Amendment and is therefore not given constitutional protections. In the 2018 case Carpenter v. United States, the Supreme Court created an exception to the third-party doctrine. In Carpenter, a case involving the warrantless use of cell site location information (CSLI) in a criminal investigation, the Court held that individuals do have a reasonable expectation of privacy regarding CSLI. According to Chief Justice Roberts, despite the necessary …

Warranted Exclusion: A Case For A Fourth Amendment Built On The Right To Exclude, Mailyn Fidler

SMU Law Review

Searches intrude; fundamentally, they infringe on a right to exclude. So that right should form the basis of Fourth Amendment protections. Current Fourth Amendment doctrine—the reasonable expectation of privacy test—struggles with conceptual clarity and predictability. The Supreme Court’s recent decision to overturn Roe v. Wade casts further doubt on the reception of other privacy-based approaches with this Court. But the replacement approach that several Justices on the Court favor, what I call the “maximalist” property approach, risks troublingly narrow results. This Article provides a new alternative: Fourth Amendment protection should be anchored in a flexible concept derived from property law—what …

The Fourth Amendment's Constitutional Home, Gerald S. Dickinson

Articles

The home enjoys omnipresent status in American constitutional law. The Bill of Rights, peculiarly, has served as the central refuge for special protections to the home. This constitutional sanctuary has elicited an intriguing textual and doctrinal puzzle. A distinct thread has emerged that runs through the first five amendments delineating the home as a zone where rights emanating from speech, smut, gods, guns, soldiers, searches, sex, and self-incrimination enjoy special protections. However, the thread inexplicably unravels upon arriving at takings. There, the constitutional text omits and the Supreme Court’s doctrine excludes a special zone of safeguards to the home. This …

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 …

The Fourth Amendment And General Law, Daniel Epps, Danielle D'Onfro

Scholarship@WashULaw

For decades, Fourth Amendment protections have turned on “reasonable expectations of privacy.” But a new era may be dawning. There is growing interest among judges and scholars in turning away from privacy toward property or positive law as the touchstone for Fourth Amendment protections. Yet many questions remain about how that approach should work, such as where judges should look for positive law and precisely what role positive law should play in Fourth Amendment analysis.

This Article answers those questions, and in so doing lays forth a new, comprehensive theory of the Fourth Amendment. We argue that courts should interpret …

Privacy And National Politics: Fingerprint And Dna Litigation In Japan And The United States Compared, Dongsheng Zang

Drawing cases from two related areas of law-fingerprint and DNA (deoxyribonucleic acid) data-this Article proposes a modified framework, built on the Balkin-Levinson emphasis on national politics: First, national politics understood as partisan rivalry cannot account for what I call doctrinal lock-in in this Article, where I will demonstrate that in different stages of American politics-the Lochner era, the New Deal era, and Civil Rights era-courts across the nation ruled predominantly in favor of public data collectors-state and federal law enforcement in fingerprint cases. From the 1990s, when DNA data became hot targets of law enforcement, the United States Supreme Court …

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 …
