The Positive Law Model Of The Fourth Amendment, William Baude, James Y. Stern
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 …
United States V. Hubbell: Encryption And The Discovery Of Documents, Gregory S. Sergienko
United States V. Hubbell: Encryption And The Discovery Of Documents, Gregory S. Sergienko
Greg Sergienko
Five years ago, in a contribution to these pages, I suggested that the Supreme Court's oldest precedents and the original intent of the framers of the Constitution precluded the use of evidence produced under a grant of immunity against the producer, even though the material produced included documents that the producer had not been compelled to write. This implied that information concealed with a cryptographic key could not be used in a criminal prosecution against someone from whom the key had been obtained under a grant of immunity. The issue, however, was doubtful given the tendency of the Court to …
Self Incrimination And Cryptographic Keys, Gregory S. Sergienko
Self Incrimination And Cryptographic Keys, Gregory S. Sergienko
Greg Sergienko
Modern cryptography can make it virtually impossible to decipher documents without the cryptographic key thus making the availability of the contents of those documents depend on the availability of the key. This article examines the Fourth and Fifth Amendments' protection against the compulsory production of the key and the scope of the Fifth Amendment immunity against compelled production. After analyzing these questions using prevailing Fourth and Fifth Amendment jurisprudence, I shall describe the advantages of a privacy-based approach in practical and constitutional terms. [excerpt]

Regulating Drones Under The First And Fourth Amendments, Stephen E. Henderson, Joseph Thai, Marc Jonathan Blitz, James Grimsley
Regulating Drones Under The First And Fourth Amendments, Stephen E. Henderson, Joseph Thai, Marc Jonathan Blitz, James Grimsley
Stephen E Henderson
The FAA Modernization and Reform Act of 2012 requires the Federal Aviation Administration to integrate unmanned aerial vehicles (UAVs), or drones, into the national airspace system by September of this year. Yet perhaps because of their chilling accuracy in targeted killings abroad, perhaps because of an increasing consciousness of diminishing privacy more generally, and perhaps simply because of a fear of the unknown, divergent UAV-restrictive legislation has been proposed in Congress and enacted in a number of states. Ultimately, given UAV utility and cost effectiveness over a vast range of tasks, widespread commercial use seems certain. So it is imperative …
Our Records Panopticon And The American Bar Association Standards For Criminal Justice, Stephen E. Henderson
Our Records Panopticon And The American Bar Association Standards For Criminal Justice, Stephen E. Henderson
Stephen E Henderson
"Secrets are lies. Sharing is caring. Privacy is theft." So concludes the main character in Dave Egger’s novel The Circle, in which a single company that unites Google, Facebook, and Twitter – and on steroids – has the ambition not only to know, but also to share, all of the world's information. It is telling that a current dystopian novel features not the government in the first instance, but instead a private third party that, through no act of overt coercion, knows so much about us. This is indeed the greatest risk to privacy in our day, both the unprecedented …
Reforming The Grand Jury To Protect Privacy In Third Party Records, Stephen E. Henderson, Andrew E. Taslitz
Reforming The Grand Jury To Protect Privacy In Third Party Records, Stephen E. Henderson, Andrew E. Taslitz
Stephen E Henderson
In late 2014, two grand juries returned controversial no bill decisions in police killings, one in Ferguson, Missouri, and one in New York City. These outcomes have renewed calls for grand jury reform, and whatever one thinks of these particular processes and outcomes, such reform is long overdue. One logical source of reform to better respect privacy in records, which would have incidental benefits beyond this privacy focus, would be the newly enacted American Bar Association Standards for Criminal Justice on Law Enforcement Access to Third Party Records (LEATPR).
But LEATPR exempts from its requirements access to records via a …

A Shattered Looking Glass: The Pitfalls And Potential Of The Mosaic Theory Of Fourth Amendment Privacy, David Gray, Danielle Citron
A Shattered Looking Glass: The Pitfalls And Potential Of The Mosaic Theory Of Fourth Amendment Privacy, David Gray, Danielle Citron
David C. Gray
On January 23, 2012, the Supreme Court issued a landmark non-decision in United States v. Jones. In that case, officers used a GPS-enabled device to track a suspect’s public movements for four weeks, amassing a considerable amount of data in the process. Although ultimately resolved on narrow grounds, five Justices joined concurring opinions in Jones expressing sympathy for some version of the “mosaic theory” of Fourth Amendment privacy. This theory holds that we maintain reasonable expectations of privacy in certain quantities of information even if we do not have such expectations in the constituent parts. This Article examines and explores …

Search, Seizure, And Immunity: Second-Order Normative Authority And Rights, Stephen E. Henderson, Kelly Sorensen
Search, Seizure, And Immunity: Second-Order Normative Authority And Rights, Stephen E. Henderson, Kelly Sorensen
Stephen E Henderson
A paradigmatic aspect of a paradigmatic kind of right is that the rights holder is the only one who can alienate it. When individuals waive rights, the normative source of that waiving is normally taken to be the individual herself. This moral feature—immunity—is usually in the background of discussions about rights. We bring it into the foreground here, with specific attention to a recent U.S. Supreme Court decision, Kentucky v. King (2011), concerning search and seizure rights. An entailment of the Court’s decision is that, at least in some cases, a right can be removed by the intentional actions of …
Real-Time And Historic Location Surveillance After United States V. Jones: An Administrable, Mildly Mosaic Approach, Stephen E. Henderson
Real-Time And Historic Location Surveillance After United States V. Jones: An Administrable, Mildly Mosaic Approach, Stephen E. Henderson
Stephen E Henderson
In United States v. Jones, the government took an extreme position: so far as the federal Constitution is concerned, law enforcement can surreptitiously electronically track the movements of any American over the course of an entire month without cause or restraint. According to the government, whether the surveillance be for good reason, invidious reason, or no reason, the Fourth Amendment is not implicated. Fortunately, that position was unanimously rejected by the High Court. The Court did not, however, resolve what restriction or restraint the Fourth Amendment places upon location surveillance, reflecting a proper judicial restraint in this nuanced and difficult …
After United States V. Jones, After The Fourth Amendment Third Party Doctrine, Stephen E. Henderson
After United States V. Jones, After The Fourth Amendment Third Party Doctrine, Stephen E. Henderson
Stephen E Henderson
In United States v. Jones, the Supreme Court unanimously rejected the proposition that the Government can surreptitiously electronically track vehicle location for an entire month without Fourth Amendment restraint. While the Court's three opinions leave much uncertain, in one perspective they fit nicely within a long string of cases in which the Court is cautiously developing new standards of Fourth Amendment protection, including a rejection of a strong third party doctrine. This Article develops that perspective and provides a cautiously optimistic view of where search and seizure protections may be headed.
More detail:
United States v. Jones, in which the …
What Alex Kozinski And The Investigation Of Earl Bradley Teach About Searching And Seizing Computers And The Dangers Of Inevitable Discovery, Stephen E. Henderson
What Alex Kozinski And The Investigation Of Earl Bradley Teach About Searching And Seizing Computers And The Dangers Of Inevitable Discovery, Stephen E. Henderson
Stephen E Henderson
This paper tells two stories. One concerns the investigation of a Delaware physician named Earl B. Bradley that resulted in a conviction and sentence of fourteen consecutive life terms for the sexual abuse of children. The other concerns the computer problems, both judicial and extra-judicial, of Chief Judge Alex Kozinski of the United States Court of Appeals for the Ninth Circuit. Though in a sense unrelated, they share lessons about the practicalities of computers and their search that are worth telling. As courts continue to struggle with how to cabin the searches of computers in order to minimize privacy intrusion …
Expectations Of Privacy In Social Media, Stephen E. Henderson
Expectations Of Privacy In Social Media, Stephen E. Henderson
Stephen E Henderson
This article, which largely tracks my remarks at Mississippi College’s Social Media Symposium, examines expectations of privacy in social media such as weblogs (blogs), Facebook pages, and Twitter tweets. Social media is diverse and ever-diversifying, and while I address some of that complexity, I focus on the core functionality, which provides the groundwork for further conversation as the technology and related social norms develop. As one would expect, just as with our offline communications and other online communications, in some we have an expectation of privacy that is recognized by current law, in some we have an expectation of privacy …
Invasion Of The Social Networks: Blurring The Line Between Personal Life And The Employment Relationship, Robert Sprague
Invasion Of The Social Networks: Blurring The Line Between Personal Life And The Employment Relationship, Robert Sprague
Robert Sprague
Over one-half billion people worldwide have registered accounts with Facebook, the most popular online social network. This article addresses some of the more significant employment-related legal issues arising from the growing popularity of online social networks. First, the need for employers to investigate the background of prospective employees is examined from the context of employers using online social networks to conduct those investigations. In particular, this article analyzes the degree to which job applicants have privacy rights in the information they post online. This article then examines the interrelationship between online social networks and employees, focusing on limitations faced by …
The Timely Demise Of The Fourth Amendment Third Party Doctrine, Stephen E. Henderson
The Timely Demise Of The Fourth Amendment Third Party Doctrine, Stephen E. Henderson
Stephen E Henderson
In what may be a slightly premature obituary, in this response to a forthcoming paper by Matthew Tokson I argue that the Fourth Amendment third party doctrine "has at least taken ill, and it can be hoped it is an illness from which it will never recover." It is increasingly unpopular as a matter of state constitutional law, has long been assailed in scholarship but now thoughtful alternatives are percolating, and it cannot – or at least should not – withstand the pressures which technology and social norms are placing upon it. Even the Supreme Court seems loath to defend …
‘Move On’ Orders As Fourth Amendment Seizures, Stephen E. Henderson
‘Move On’ Orders As Fourth Amendment Seizures, Stephen E. Henderson
Stephen E Henderson
If a police officer orders one to move on, must the recipient comply? This article analyzes whether there is a federal constitutional right to remain, and in particular whether a police command to move on constitutes a seizure of the person for purposes of the Fourth Amendment. Although it is a close question, I conclude that the Fourth Amendment typically does not restrict a move on (MO) order, and that substantive due process only prohibits the most egregious such orders. It is a question of broad significance given the many legitimate reasons police might order persons to move on, as …

Beyond The (Current) Fourth Amendment: Protecting Third-Party Information, Third Parties, And The Rest Of Us Too, Stephen E. Henderson
Stephen E Henderson
For at least thirty years the Supreme Court has adhered to its third-party doctrine in interpreting the Fourth Amendment, meaning that so far as a disclosing party is concerned, information in the hands of a third party receives no Fourth Amendment protection. The doctrine was controversial when adopted, has been the target of sustained criticism, and is the predominant reason that the Katz revolution has not been the revolution many hoped it would be. Some forty years after Katz the Court's search jurisprudence largely remains tied to property conceptions. As I have demonstrated elsewhere, however, the doctrine is not the …
Learning From All Fifty States: How To Apply The Fourth Amendment And Its State Analogs To Protect Third Party Information From Unreasonable Search, Stephen E. Henderson
Learning From All Fifty States: How To Apply The Fourth Amendment And Its State Analogs To Protect Third Party Information From Unreasonable Search, Stephen E. Henderson
Stephen E Henderson
We are all aware of, and many commentators are critical of, the Supreme Court's third-party doctrine, under which information provided to third parties receives no Fourth Amendment protection. This constitutional void becomes increasingly important as technology and social norms dictate that increasing amounts of disparate information are available to third parties. But we are not solely dependent upon the Federal Constitution. We may have more constitutional protection as citizens of states, each of which has a constitutional cognate or analog to the Federal Fourth Amendment. As Justice Brennan urged in a famous 1977 article, those provisions should be interpreted to …
