Heads of state and crises

Characterized as a disruption of equilibrium, crises today are often global or regional. Nevertheless, national legal orders retain a major competence for crisis management in the face of the inertia, inaction or lack of competence of supranational orders. In the face of crisis, the need to act and decide arises, and for the constitutionalist or political theorist, the question of who should or can do so. The aim of this book is to study political theories designed to analyze, justify or criticize the crisis powers of heads of state around the world, as well as the substance of these powers. The perspective adopted is therefore at once theoretical, historical and comparative.
