Contracting for Catastrophe:Legitimizing Emergency Constitutions by Drawing on Social Contract Theory.

States of emergency are declared frequently in all parts of the world. Their declaration routinely implies a suspension of basic constitutional rights. In the last half century, it has become the norm for constitutions to contain an explicit 'emergency constitution', i.e., the constitutionally safeguarded rules of operation for a state of emergency. In this paper, I ask whether inclusion of an emergency constitution can be legitimized by drawing on social contract theory. I argue that there are important arguments, both against and in favor of constitutionalized emergency provisions, and that social contract theory-as applied by economists-can be of some help when deciding whether to have, or not to have an emergency constitution. This paper introduces a novel argument for justifying emergency constitutions. It argues that they can serve as a commitment mechanism protecting both citizens and politicians from overreacting to rare but significant threats.
