Cops And Cars: How The Automobile Drove Fourth Amendment Law, Tracey Maclin

Faculty Scholarship

This is an essay on Professor Sarah A. Seo’s new book, Policing the Open Road: How Cars Transformed American Freedom (Harvard Univ. Press 2019). I focus on Professor Seo’s analysis of Carroll v. United States, 267 U.S. 132 (1925) and Brinegar v. United States, 338 U.S. 160 (1949). Carroll is important not only because it was the Court’s first car case. Understanding Carroll (and Brinegar, which solidified and expanded Carroll’s holding) is essential because, nearly one hundred years later, its logic continues to direct how the modern Court resolves Fourth Amendment claims of motorists. Put simply, a majority of today’s …

The Positive Law Model Of The Fourth Amendment, William Baude, James Y. Stern

James Y. Stern

For fifty years, courts have used a “reasonable expectation of privacy” standard to define “searches” under the Fourth Amendment. As others have recognized, that doctrine is subjective, unpredictable, and conceptually confused, but viable alternatives have been slow to emerge. This Article supplies one.

We argue that Fourth Amendment protection should be anchored in background positive law. The touchstone of the search-and-seizure analysis should be whether government officials have done something forbidden to private parties. It is those actions that should be subjected to Fourth Amendment reasonableness review and the presumptive requirement to obtain a warrant. In short, Fourth Amendment protection …

The Case For The Third-Party Doctrine, Orin S. Kerr

Orin Kerr

This Article offers a defense of the Fourth Amendment's third party doctrine, the controversial rule that information loses Fourth Amendment protection when it is knowingly revealed to a third party. Fourth Amendment scholars have repeatedly attacked the rule on the ground that it is unpersuasive on its face and gives the government too much power This Article responds that critics have overlooked the benefits of the rule and have overstated its weaknesses. The third-party doctrine serves two critical functions. First, the doctrine ensures the technological neutrality of the Fourth Amendment. It corrects for the substitution effect of third parties that …

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 …

When A Tent Is Your Castle: Constitutional Protection Against Unreasonable Searches Of Makeshift Dwellings Of Unhoused Persons, Evanie Parr

Seattle University Law Review

This Note will argue that all jurisdictions should follow the Washington State Court of Appeals, Division II in validating makeshift dwellings used by people experiencing homelessness as spaces protected from unwarranted police intrusions by shifting evaluations of “reasonable expectations of privacy” to a more equitable standard that appreciates the realities of economic disparity. This approach to constitutional protections against unreasonable searches and seizures is imperative to protect the rights of people experiencing homelessness, given that such individuals are regularly subjected to invasions of privacy and heightened exposure to the criminal justice system.

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

Articles in Law Reviews & Other Academic 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 …

Byrd V United States: Unauthorized Drivers Of Rental Cars Have Fourth Amendment Rights? Not As Evident As It Seems, Tracey Maclin

Faculty Scholarship

No discerning student of the Supreme Court would contend that Justice Anthony Kennedy broadly interpreted the Fourth Amendment during his thirty years on the Court. His majority opinions in Maryland v. King, Drayton v. United States and his willingness to join the three key sections of Justice Scalia’s opinion in Hudson v. Maryland, which held that suppression is never a remedy for knock-and-announce violations, are just a few examples of Justice Kennedy’s narrow view of the Fourth Amendment.

In light of his previous votes in search and seizure cases, surprisingly Justice Kennedy, in what would be his final Fourth Amendment …

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 …

Functional Equivalence And Residual Rights Post-Carpenter: Framing A Test Consistent With Precedent And Original Meaning, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

The Carpenter Court held that warrantless access to seven or more days of cell site location information (CSLI) constitutes a violation of the reasonable expectation of privacy that individuals have in the whole of their physical movements. But the grounds on which the Court drew a line characterize all sorts of digital records—including those at issue in Miller and Smith, belying the majority’s claim that the decision leaves third-party doctrine intact. Instead of avoiding Katz’s pitfalls, moreover, the Court emphasized voluntary assumption of risk, doubling down on the subjective nature of judicial determination. The decision will likely lead to …
