"Justice in the distribution of the world's resources" is a theoretical study of the concept of distributive justice according to Aristotle's and Rawls' theories of justice, and its application in the international relations among States against the background of the 20th century's movement of the New International Economic Order (NIEO). It is also, and perhaps primarily, an empirical study of the various manifestations of the concept of the Common Heritage of Mankind in the resource-management regimes of the deep seabed, the Moon, the Geostationary Orbit and Antarctica, and of the concept of "equitable use and allocation" in the resource-management regimes of common oil and natural gas deposits, fishery and international watercourses. It is finally, an enquiry into the definitional content and normative value of the concept of distributive justice in its application to both universal and shared resources by reference to the theories of sources of international law
