State borders as defining lines of justice: why the right to exclude cannot be justified

This paper seeks to answer the question of what we, according to justice, owe to immigrants. The answer to this normative question is extracted by providing an analysis of Michael Blake’s jurisdictional theory presented in Immigration, Jurisdiction, and Exclusion and elaborated upon in other articles in which he argues for states’ right to exclude immigrants based on states’ jurisdictional nature. I regard this theory as unjustified since it rests on a weak basis, which is further problematised by weighing the moral claims of residents above those of immigrants. In this way, my criticism serves to provide argumentative support in a negative manner for weighing the moral claims of immigrants on an equal footing with those of residents.
