The Possibility of Interimperial Law

This article identifies the contemporary criteria of imperiality and then considers the normative aspects of the existence of certain great powers (empires) in international relations. It is argued that there is a body of norms valid among empires that may be referred to as interimperial law, in the sense of a normative order that is intended to lower the costs and dangers of competition between empires. The article outlines a basic theory of coexistence between the emerging interimperial law and the existing international law, derived from theoretical and historical models of the coexistence of various legal orders within one territory.
