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”).

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 …

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 …

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 …

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 …

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

Articles

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 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 …

Thompson V. Clark And The “Reasonable” Policing Of Marginalized Families, Anna Arons

Faculty Publications

This Article uses the experience of Larry Thompson, the plaintiff in Thompson v. Clark, 142 S. Ct. 1332 (2022), to examine the absence of privacy for poor families, particularly poor Black, Latinx, and Native families, in the United States. Mr. Thompson may end up remembered in legal history as a victor, as the Supreme Court lowered the barriers to bringing malicious prosecution claims and reinstated Mr. Thompson’s own previously dismissed malicious prosecution claim. Yet before securing this victory, Mr. Thompson lost a slew of other Fourth Amendment claims against the police. Mr. Thompson’s claims arose from state agents’ warrantless …

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 …

Fourth Amendment Notice In The Cloud, Neil M. Richards, Jesse Lieberfeld

Scholarship@WashULaw

The widespread storage of documents through the range of Internet technologies known as “the cloud” offers tremendous convenience but also creates significant risks of exposure to third parties. In particular, law enforcement investigators seeking access to potentially relevant evidence have aggressively and extensively used the Electronic Communications Act of 1986 (“ECPA”) to execute digital searches. But a relatively obscure provision of ECPA, § 2703, allows law enforcement to search a person’s Fourth Amendment “papers” without them ever learning that a warrant has allowed the exposure of their private, sensitive, and possibly incriminating documents. What is more, federal and state law …

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 …

Are Police Officers Bayesians? Police Updating In Investigative Stops, Jeffrey A. Fagan, Lila J.E. Nojima

Faculty Scholarship

Theories of rational behavior assume that actors make decisions where the benefits of their acts exceed their costs or losses. If those expected costs and benefits change over time, behavior will change accordingly as actors learn and internalize the parameters of success and failure. In the context of proactive policing, police stops that achieve any of several goals — constitutional compliance, stops that lead to “good” arrests or summonses, stops that lead to seizures of weapons, drugs, or other contraband, or stops that produce good will and citizen cooperation — should signal to officers the features of a stop that …

Scanning Iphones To Save Children: Apple’S On-Device Hashing Algorithm Should Survive A Fourth Amendment Challenge, Timothy Gernand

Dickinson Law Review (2017-Present)

When Apple announced it would combat the growth of child sexual abuse material (CSAM) on its platform by scanning all its users’ devices without their consent, many of its loyal customers felt betrayed. With tech companies such as Google and Facebook arranging their business models around selling their customers’ personal information, Apple customers saw the company’s focus on privacy as a refreshing alternative. However, as Apple itself privately acknowledged, this emphasis on privacy had led to it becoming a haven for CSAM. Despite the reputational damage it would incur with its customers, Apple resolved to confront CSAM on its platform …

The Fourth Amendment And The Problem Of Social Cost, Thomas P. Crocker

Northwestern University Law Review

The Supreme Court has made social cost a core concept relevant to the calculation of Fourth Amendment remedies but has never explained the concept’s meaning. The Court limits the availability of both the exclusionary rule and civil damages because of their “substantial social costs.” According to the Court, these costs primarily consist of letting the lawbreaker go free by excluding evidence or deterring effective police practices that would lead to more criminal apprehension and prosecution. But recent calls for systemic police reform by social movements have a different view of social cost. So too do calls for reforming qualified immunity. …

Legal Implications Of A Ubiquitous Metaverse And A Web3 Future, Jon M. Garon

Marquette Law Review

The metaverse is understood to be an immersive virtual world serving as the locus for all forms of work, education, and entertainment experiences. Depicted in books, movies, and games, the metaverse has the potential not just to supplement real-world experiences but to substantially supplant them. This Article explores the rapid emergence and evolution of the Web3 technologies at the heart of the metaverse movement. Web3 itself is a paradigmatic shift in internet commerce.

Rewriting Whren V. United States, Devon W. Carbado, Jonathan Feingold

Faculty Scholarship

In 1996, the U.S. Supreme Court decided Whren v. United States—a unanimous opinion in which the Court effectively constitutionalized racial profiling. Despite its enduring consequences, Whren remains good law today. This Article rewrites the opinion. We do so, in part, to demonstrate how one might incorporate racial justice concerns into Fourth Amendment jurisprudence, a body of law that has long elided and marginalized the racialized dimensions of policing. A separate aim is to reveal the “false necessity” of the Whren outcome. The fact that Whren was unanimous, and that even progressive Justices signed on, might lead one to conclude that …

A Solution For The Third-Party Doctrine In A Time Of Data Sharing, Contact Tracing, And Mass Surveillance, Tonja Jacobi, Dustin Stonecipher

Notre Dame Law Review

Today, information is shared almost constantly. People share their DNA to track their ancestry or for individualized health information; they instruct Alexa to purchase products or provide directions; and, now more than ever, they use videoconferencing technology in their homes. According to the third-party doctrine, the government can access all such information without a warrant or without infringing on Fourth Amendment privacy protections. This exposure of vast amounts of highly personal data to government intrusion is permissible because the Supreme Court has interpreted the third-party doctrine as a per se rule. However, that interpretation rests on an improper understanding of …

The Computer Got It Wrong: Facial Recognition Technology And Establishing Probable Cause To Arrest, T.J. Benedict

Washington and Lee Law Review

Facial recognition technology (FRT) is a popular tool among police, who use it to identify suspects using photographs or still-images from videos. The technology is far from perfect. Recent studies highlight that many FRT systems are less effective at identifying people of color, women, older people, and children. These race, gender, and age biases arise because FRT is often “trained” using non-diverse faces. As a result, police have wrongfully arrested Black men based on mistaken FRT identifications. This Note explores the intersection of facial recognition technology and probable cause to arrest.

Courts rarely, if ever, examine FRT’s role in establishing …

The Problem Of Qualified Immunity In K-12 Schools, Sarah Smith

Arkansas Law Review

When thirteen-year-old Savana Redding arrived at school one autumn day in 2003, she was not expecting to be pulled out of her math class and strip searched. But, that is exactly what happened after the assistant principal suspected her of possessing and distributing “prescription-strength ibuprofen” and “over-the-counter. . .naproxen” after receiving information from another student. After Savana consented to a search of her backpack and other belongings—a search which turned up no evidence of drug possession—the assistant principal asked the school nurse and administrative assistant to search Savana’s clothes. To do this, the school officials asked Savana “to remove her …

Tech And Authoritarianism: How The People’S Republic Of China Is Using Data To Control Hong Kong And Why The U.S. Is Vulnerable, Bryce Neary

Seattle Journal of Technology, Environmental, & Innovation Law

The aim of this article is to analyze and compare current events in the People's Republic of China and the United States to discuss the moral dilemmas that arise when establishing the boundary between national security interests and individual privacy rights. As we continue to intertwine our lives with technology, it has become increasingly important to establish clear privacy rights. The question then becomes: at what point should individuals sacrifice their rights for what the government considers the "greater good" of the country?

Further, this article analyzes the development of U.S. privacy law and its relationship to national security, technology, …

Telephone Pole Cameras Under Fourth Amendment Law, Matthew Tokson

Utah Law Faculty Scholarship

In a series of recent cases, police officers have mounted sophisticated surveillance cameras on telephone poles and pointed them at the homes of people suspected of a crime. These cameras often operate for months or even years without judicial oversight, collecting vast quantities of video footage on suspects and their activities near the home. Pole camera surveillance raises important Fourth Amendment questions that have divided courts and puzzled scholars.

These questions are complicated because Fourth Amendment law is complicated. This is especially the case today as Fourth Amendment law is in a transitional phase, caught between older and newer paradigms …

Regulatory Constitutional Law: Protecting Immigrant Free Speech Without Relying On The First Amendment, Michael Kagan

Georgia Law Review

The Supreme Court has long deprived immigrants of the full protection of substantive constitutional rights, including the right to free speech, leaving undocumented immigrants exposed to detention and deportation if they earn the government’s ire through political speech. The best remedy for this would be for the Supreme Court to reconsider its approach. This Essay offers an interim alternative borrowed from an analogous problem that arises under the Fourth Amendment. Under the Constitution, the Supreme Court has indicated that illegally obtained evidence may be suppressed in a removal proceeding only if the Fourth Amendment violation was “egregious.” Yet, some circuit …

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 …
