Katz'S Imperfect Circle: An Empirical Study Of Reasonable Expectations Of Privacy, Tonja Jacobi, Christopher Brett Jaeger

Faculty Articles

Under Katz v. United States, the Fourth Amendment restricts government actions that infringe upon expectations of privacy that society recognizes as reasonable. This foundational test has long been criticized as circular, both because courts can shape the very expectations they seek to identify through their decisions and because governments can manipulate those expectations to expand the reach of their own power. But how do members of society decide what expectations are reasonable, and how do judges ascertain those expectations? And are expectations of privacy malleable even without deliberate manipulation?

This Article shows that the circularity critique is both understated …

Office Intent And Excessive Force, John F. Preis

Law Faculty Publications

In the mayhem that often accompanies a police officer’s use of force, all manner of mistakes and miscalculations can occur. Suspects are accidentally shot, innocent bystanders are bitten by police dogs, and hostages are killed instead of their kidnappers. To what degree may persons harmed by police mistakes obtain relief through excessive force claims?

At present, the answer to this question is surprisingly uncertain. It is clear that an excessive force claim requires that an officer intend to seize the suspect, but it is far less clear whether the officer must also intend the nature and extent of force used …

The Evolution Of Surveillance And The Decline Of Privacy, Alan J. Geyer

Honors Undergraduate Theses

This study directly examines how surveillance law and technology have evolved in the United States and how privacy rights have declined correspondingly. The study specifically focuses on how advancements in surveillance technology have overstepped the boundaries of Fourth Amendment protections and analyzes whether these provisions are adequate for protecting citizens in the modern technological era. The study explores newly employed methods of technological surveillance, such as facial recognition, data collection, and automated license plate readers. It focuses on how government surveillance programs have reshaped legal and ethical understandings of privacy. The changes in surveillance and technology have been analyzed by …

Free Movement Rights And The American City, Ryan Stoa

FIU Law Review

American cities are facing an inflection point. Widespread dissatisfaction with urban planning outcomes is making land use and transportation policies (such as congestion pricing) a mainstream topic of debate. Suburban sprawl and housing shortages are moving urban populations into the periphery, commuting times (and associated mental health problems) are increasing, and pedestrian and cyclist deaths caused by vehicles are at all-time highs. American cities that were largely planned and built in the twentieth century based on assumptions that we now know are flawed are not meeting the needs of their residents, and urban planners are making changes to reshape urban …

“Digital Integrity”: Defending The Judicial Integrity In The Digital Age, Guy Alon, Doron Menashe, Guy Itzhak Sender

Touro Law Review

Recent revelations have shown that the protection of the Fourth Amendment in the digital age is inadequate. Despite well-known exclusionary rules regarding evidence obtained by illegal search and seizure, current trends in the digital age and the law of evidence resulted in courts that tend to include such evidence, and by doing so, create significant risk of both substantive and procedural errors and hence increase the potential for wrongful convictions. To address the matter and try to empower and modernize the protection given by the Fourth Amendment, this article suggests performing a revolution in the law of evidence in the …

Loopholes Of Liberty: The Supreme Court’S Evisceration Of The Fourth Amendment, David J. Looney

Touro Law Review

The Fourth Amendment’s protections against unwarranted government intrusion are currently undermined by the Supreme Court’s third party and open fields doctrines, which permit warrantless access to shared data and private land beyond a home’s curtilage, clashing with the Amendment’s aim to safeguard privacy and property in an era of advanced surveillance. These doctrines enable arbitrary governmental overreach, necessitating urgent review to restore constitutional protections. Rooted in Enlightenment principles, the Fourth Amendment historically protected “papers” and “effects” from physical trespass, as seen in Boyd v. United States. Katz v. United States introduced a “reasonable expectation of privacy” test, but its subjective …

Family Regulation's Consent Problem, Anna Arons

Faculty Publications

The home is the most protected space in constitutional law. But family regulation investigators conduct millions of home searches a year. Under pressure, parents nearly always consent to these state agents’ entry into the most private areas of their lives.

This Article identifies the coercive forces—not least the threat of family separation—that drive parents to consent to home searches. Drawing on primary sources and case law examining consent in criminal cases, it shows that common family regulation investigation tactics render consent involuntary and the ensuing searches unconstitutional. And yet, it argues, the Constitution is not enough. Though constitutional litigation could …

Voting Matters: Materiality Considerations And The Shareholder Vote, Renee M. Jones

Seattle University Law Review

For the shareholder franchise to have meaning, shareholders must have access to relevant information to inform their voting decisions. The securities laws’ disclosure requirements play an essential role in informing the shareholder vote.

This Essay focuses on the question of the materiality of information in the context of shareholder voting. It addresses the question of whether ESG-related information is material, positioning the materiality inquiry within the context of shareholders’ voting decisions. It explores the definition of materiality with a focus on the “reasonable investor” concept embedded within the definition. The Essay argues that the implicit expectations of many commentators that …

Understanding The Big Three’S Wavering Support Of Environmental And Social Shareholder Proposals, Jeff Schwartz, Jefferson Jensen

Seattle University Law Review

Because of their substantial equity portfolios, BlackRock, Vanguard, and State Street (the Big 3) are central players in corporate governance. It is, therefore, critical to understand how they vote. One puzzle is that their support for shareholder proposals on environmental and social matters appears to waiver. In 2020, for instance, BlackRock supported 11.1% of environmental proposals at S&P 500 firms. In 2021, it seemingly reversed course, supporting 55.2%. It then flipped again, supporting 32.1% in 2022. Such statistics suggest that the Big 3 are constantly changing their views on these topics. This Article seeks to better understand whether this is …

Consensus And Conflict Over Context: Select Criminal Law And Procedure Cases From The Supreme Court's 2024-25 Term, Eve Brensike Primus, Elena Schultz

Articles

In its 2024-2025 Term, the Supreme Court emphasized the utility—and necessity—of context-based, fact-sensitive analyses throughout its criminal law and procedure cases. Though the Justices sparred over how to derive meaning from factual, structural, legal, and historical contexts, they tended to agree that courts should not be artificially restricted from considering the breadth of the record before them.

Decentering Property In Fourth Amendment Law, Michael C. Pollack, Matthew Tokson

Articles

For the past several decades, privacy has been the primary conceptual foundation for Fourth Amendment search law. The canonical test for Fourth Amendment searches accordingly looks to whether the government has violated a person’s reasonable expectation of privacy. Yet privacy is no longer the sole determinant of Fourth Amendment protection, as the Supreme Court has recently added a property-based test to address cases involving physical intrusions on land or chattel. Further, given the ambiguity of the reasonable expectation of privacy test, a variety of influential judges and scholars have proposed relying primarily, or even exclusively, on property in determining the …

Facial Recognition Technology And The First Amendment, Joseph A. Tomain

Articles by Maurer Faculty

The growing ubiquity of facial recognition technology (FRT) is a problem. While much has been written on harmful government use of FRT, little has been written regarding harmful private actor use. This Article helps fill a gap in the literature by providing a detailed analysis of the First Amendment interests at stake when private actors use FRT. Specifically, this Article analyzes whether laws that limit the use of publicly available photographs to create faceprints for inclusion in FRT databases violate the First Amendment rights of private actors.

In May 2025, a multidistrict litigation against Clearview AI, an FRT company, offered …

The Fourth Amendment's Hidden Intrusion Doctrine, Laura Ginsberg Abelson

Faculty Journal Articles and Book Chapters

The Fourth Amendment’s concept of probable cause is the linchpin of legal standards governing law enforcement actions such as arrests, searches, and seizures. This article challenges the assumption that the same quantum of evidence can meet the probable cause standard regardless of whether law enforcement seek to conduct a search, to seize evidence, or to make an arrest, and regardless of the intrusiveness of such search or seizure. This paper demonstrates that the Supreme Court implicitly considers the degree of intrusion into privacy or liberty, not just the quantum or quality of evidence, when determining whether probable cause exists. In …

State V. Sweatt: An Examination Of The Current Confusion In Fourth Amendment Standing, John Archer Hobson

Maine Law Review

In State v. Sweatt the Maine Law Court held that an owner of gems being sold on consignment in a third party's store has standing under the fourth amendment to contest the seizure of the gems. The movants in Sweatt were the targets of several police searches during October and November of 1980. During these searches the police seized tourmaline gemstones which were alleged to have been stolen from Dale Sweatt's former business partner, and miscellaneous personal items belonging to the Sweatts. Subsequently, the Sweatts moved for suppression and return of all these articles. The superior court granted the movants' …

Utah V. Strieff And Teaching Analysis, Lisa A. Tucker

St. John's Law Review

(Excerpt)

In Utah v. Strieff, the Supreme Court considered whether the Fourth Amendment required suppression of evidence obtained in an unlawful investigatory stop when police discovered that the person stopped was subject to lawful arrest based on an unrelated outstanding warrant. The majority opinion, written by Justice Clarence Thomas, held that suppression was not required in such a case; the dissent by Justice Sotomayor argued that it should be.

These two legal opinions took jarringly different approaches to determining a question of law, one that disproportionately impacts people of color, who are statistically most likely to be unlawfully stopped …
