Pure Privacy, Jeffrey Bellin

Northwestern University Law Review

In 1890, Samuel Warren and Louis Brandeis began a storied legal tradition of trying to conceptualize privacy. Since that time, privacy’s appeal has grown beyond those authors’ wildest expectations, but its essence remains elusive. One of the rare points of agreement in boisterous academic privacy debates is that there is no consensus on what privacy means.

The modern trend is to embrace the ambiguity. Unable to settle on boundaries, scholars welcome a broad array of interests into an expanding theoretical framework. As a result, privacy is invoked in debates about COVID-19 contact tracing, police body cameras, marriage equality, facial recognition, …

Northwestern University Law Review

In light of the privacy concerns inherent to personal technological devices, the Supreme Court handed down a unanimous decision in 2014 recognizing the need for categorical heightened protection of cell phones during searches incident to arrest in Riley v.

This argument matters because state and federal courts have not provided the needed protection to abandoned cell phones pre- or post-Riley.

This Article fills that gap. It starts by identifying the characteristics of Fourth Amendment knowledge. It finds, …

Forced Decryption As Equilibrium—Why It’S Constitutional And How Riley Matters, Dan Terzian

Northwestern University Law Review

This Essay considers whether the government can force a person to decrypt his computer. The only courts to consider the issue limited their analyses to rote application of predigital doctrine and dicta. This is a mistake; courts should instead aim to maintain the ex ante equilibrium of privacy and government power. This approach—seeking equilibrium—was just endorsed by the Supreme Court in Riley v. California, a recent Fourth Amendment case. Yet Riley’s rationale also extends to the Fifth Amendment’s Self-Incrimination Clause, and maintaining equilibrium there requires permitting forced decryption. Because current doctrine can be interpreted as allowing forced decryption, …
