This collection brings together well-established scholars to examine the limits of law, a topic that has been of broad interest since the events of 9/11 and the responses of U.S. law and policy to those events. The limiting conditions explored in this volume include marking law’s relationship to acts of terror, states of emergency, gestures of surrender, payments of reparations, offers of amnesty, and invocations of retroactivity. These essays explore how law is challenged, frayed, and constituted out of contact with conditions that lie at the farthest reaches of its empirical and normative force.
