“Are We There Yet?”: The Long Journey To Defining Motor Home Protections Under The Fourth Amendment, Ilse Ghent

Arkansas Law Review

From the time of the Revolutionary War, United States citizens have prioritized one thing over almost everything else: that “a man’s house is his castle.” This is immortalized in the Fourth Amendment’s prohibition against unreasonable and warrantless searches. The protections granted by the Fourth Amendment are not centered around the rights a person has in their property. Instead, “the principal object of the Fourth Amendment is the protection of privacy rather than property.” This protection is so important that the Supreme Court has been explicitly clear that warrantless searches should only be permitted in the most “exceptional” of circumstances. One …

Race, The Academy, And The Constitution Of The War On Drugs, Jeffrey Bellin, Bennett Capers

Vanderbilt Law School Faculty Publications

The war on drugs is widely viewed as a policy failure. Despite massive government intrusions on personal liberty, drug addiction, overdoses, and drug-related violence have only in- creased since the war was declared in 1971. David Pozen's new book, The Constitution of the War on Drugs, reveals a constitutional failure as well. Pozen chronicles a host of constitutional arguments that American litigants deployed to protect a "right" to use drugs with surprising, if fleeting, suc- cess. Pozen asks what might have been, exploring why the courts backtracked and effectively re- moved the Constitution as a meaningful obstacle to drug prohibitions. …

Trespass To Chattel And The Fourth Amendment, Will Baskin

Texas A&M Journal of Property Law

Like an adolescent maturing into adulthood, Fourth Amendment search doctrine has gone through phases. Scholars may debate the underlying principles that have governed each phase, but they agree that two Supreme Court decisions dominate the doctrine as it stands today: Katz v. United States and United States v. Jones. The younger of these two rivals, Jones, has caused its share of consternation. Courts have struggled to consistently apply its trespass-based test, despite the test’s seemingly simple formulation. This Note considers the Jones test in the context of personal property, or chattel, making two arguments: first, careful adherence to common-law principles …

Peeping Town: Drone Surveillance And The Exclusionary Rule In Long Lake Township V. Maxon, Stuart Massa

Northwestern University Law Review

For years, legal commentators have pondered the effect of the Fourth Amendment on drones, but purely as an academic exercise. No court had ever considered drone surveillance under the Fourth Amendment––until now. In Long Lake Township v. Maxon, a northern Michigan township flew a drone over a local resident’s home to gather photographic evidence of an alleged zoning violation. Relying on that evidence, the township sued to enforce its zoning ordinance. The resident moved to suppress the evidence, arguing that the drone’s warrantless surveillance violated the Fourth Amendment. The case made it all the way up to the Michigan …

Policing As General Warrants, Warren Buff, Brandon Hasbrouck

Scholarly Articles

The drafters of the Bill of Rights and its proponents envisioned a document constitutionalizing protections against some of the worst abuses they had experienced under English rule. Prominent businessmen—many of them engaged in smuggling— found their homes ransacked in search of contraband on flimsy evidence and without any reason given for the disruption of their business and consequent enrichment of government agents. The Fourth Amendment addressed the use of general warrants and writs of assistance to allow government agents to conduct broad searches with limited scrutiny. In the early years of the Constitution, this had little practical effect, because public …

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 …

Through A Glass Darkly: How Securities Disclosures Give A Distorted View Of The Economy, Gerald F. Davis

Seattle University Law Review

Our understanding of the American economy often relies on stylized facts derived from mandatory disclosures by listed corporations. Data vendors like Standard & Poor’s vacuum up 10Ks and proxy statements into databases, and scholars distill these into tentative maps. This may have been adequate for a postwar economy centered on asset-heavy manufacturers, but it is increasingly out of step with an information-based economy. Companies listed on the stock market are fewer in number and less representative than they were, light in tangible assets and people, and heavy on IP. Basic facts such as what industry they are in are increasingly …

Shareholder Expression In A Time Of Heightened Political Tension, Aaron A. Dhir

Seattle University Law Review

In this article, I provide context for my forthcoming research project on shareholder proposals and racial equity audits. Since the murder of George Floyd in May of 2020, progressive shareholder actors have increasingly used the proposal mechanism to advance diversity, equity, inclusion, and justice-related goals. These proposals have frequently gone beyond requesting the usual corporate fare of diversity trainings, intersectionality workshops, affinity groups, etc. Instead, a more ambitious type of proposal asks corporate America to conduct racial equity audits, defined as “an independent, objective and holistic analysis of a company’s policies, practices, products, services and efforts to combat systemic racism …

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 …

“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 …

The Reality Of The Good Faith Exception, Matthew Tokson, Michael Gentithes

Utah Law Faculty Scholarship

The Fourth Amendment’s primary remedy is the exclusion of unlawfully obtained evidence at trial. But not every defendant whose rights are violated gets a remedy. The most substantial obstacle for defendants is the good faith exception, which directs courts to admit unlawfully collected evidence if the police can show they relied in good faith on existing authority. If the police rely on a statute that turns out to be unconstitutional, or a warrant or precedent that turns out to be invalid, the evidence they obtain will nonetheless be admitted under the good faith exception. The Supreme Court has justified this …

Corporate Governance Speech, Sarah C. Haan

Seattle University Law Review

The State has always regulated the intra-firm communications that make corporate governance possible, most commonly by mandating disclosures of information by a corporation to its shareholders. Some such laws are labeled “securities regulation,” but securities regulation is a broad category that extends to speech by actors who are outside the corporate enterprise as well. Also, the conventional securities regulation category does not capture all such laws; other examples, including informationforcing mandates, can be found in state corporate law. This Article uses the term “corporate governance speech” to describe the communications among shareholders, directors, and officers through which corporate governance is …

Green Dividends: A Case Study In Green Dividends And The Conditions For Private Ordering Solutions, Anne M. Tucker

Seattle University Law Review

This Essay introduces a novel private ordering solution to facilitate corporate investments in pro-social and environmental initiatives: Green dividends. Green dividends are an optional increase in shareholder dividends that are returned to the company to be reinvested in environmental initiatives or kept by a shareholder.

Green dividends pose an alternative to the current gridlocked debate that corporations can’t, won’t, shouldn’t, and shouldn’t even try to act in pro-social or environmental ways. Turning the common refrains on their head converts each narrative into an element for a successful private ordering solution: authority, accountability, shareholder buy-in, and government- backed enforcement. With Green …

Does Climate Disclosure Work To Reduce Greenhouse Gas Emissions? Emerging Evidence Suggests Cautious Optimism, Cynthia A. Williams

Seattle University Law Review

Significant regulatory resources have been spent developing global, voluntary climate and sustainability disclosure standards, such as the TCFD, TNRD, and ISSB’s Sustainability and Climate Disclosure standards, or domestically required disclosures, such as in the EU and in the U.S. Thus, it is important to evaluate whether this disclosure, particularly voluntary, qualitative disclosure, will have the power to shift the allocation of capital, will have a significant effect on the management of climate risk within firms, and ultimately will reduce climate change risk and biodiversity loss.

In this Article, several interrelated questions will be discussed. First, what does the empirical evidence …

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 …

Corporate Scenarios: Drawing Lessons From History, Madison Condon

Seattle University Law Review

As corporations are increasingly pressed to reveal information about their exposure to climate-related risks, they are often asked to undertake and disclose the outcome of “scenario analysis.” In this exercise, corporations, including financial institutions, examine how their business would fare under different pathways the future may take. One oft-used scenario, for example, is the International Energy Agency’s “Net-Zero by 2050: A Roadmap for the Energy Sector.” This Essay presents a history of the use of scenarios as a corporate planning tool, particularly in the oil industry, arguing that it is key for understanding our present moment and the role of …

Dark Accounting Matter, Colleen Honigsberg

Seattle University Law Review

Physicists calculate that approximately 85% of the matter in the universe is composed of “dark matter” that “does not absorb, reflect, or emit electromagnetic radiation and is therefore difficult to detect.” The S&P 500 currently trades at a price-to-book value of 4.2, suggesting that book value accounts for less than 20% of the S&P 500’s market value. The remaining 80% appears nowhere in these firms’ balance sheets—it is invisible to contemporary accounting techniques and constitutes “dark accounting matter.”

Some “dark accounting matter” is composed of factors commonly described as components of “ESG.” Human capital, for example, is an intangible asset …

The Warrant Exception That Isn't: Fisa Section 702, "Defensive" Searches, And The Fourth Amendment, Noah C. Chauvin

Faculty Articles

Section 702 of the Foreign Intelligence Surveillance Act allows the government to conduct warrantless electronic surveillance of non-Americans who are located overseas. Although the surveillance targets foreigners, Americans' communications are "incidentally" collected, too. Once the government has acquired Americans' communications, court-approved rules allow it to conduct warrantless searches for and through them in its Section 702 databases. Intelligence agencies have used these rules to turn this foreign intelligence program into a domestic spying tool, conducting tens of thousands of warrantless "backdoor" searches for Americans' private communications obtained under Section 702 every year.

Section 702 periodically sunsets; Congress most recently reauthorized …

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 …
