Obligations of justice: Open borders or distributive justice?

This paper criticizes traditional positions about the discretional competence of states regarding the access of immigrants, and asks whether the right for free mobility or obligations of global distributive justice follows from the standpoint of global justice. According to the argument, much seems to speak in favor of global distributive justice if global justice is exclusively concerned about inequality of opportunity and poverty. However, even if this is the case significant restrictions on state discretional competence regarding immigration issues should be recognized.
