ABSTRACT
This chapter investigates whether it is possible to have a global theory of justice in migration and, if so, on what kind of principles it should be grounded. It introduces the definitions of some key terms and outlines the methodological preliminaries. The chapter discusses the circumstances and requirements of justice in immigration and emigration, respectively. It also identifies a tension between such requirements and illustrates how a global theory of just migration based on egalitarian principles leads to a paradox. The chapter also focuses on how to save justice in migration from being largely a closed borders utopia. It also assesses legitimate and illegitimate restrictions on long-term migration and investigates the distribution of benefits and responsibilities between all affected parties. Of course that closed borders utopia would be unjust to migrants themselves. It would compromise freedom of movement in ways that, if consistent with the general principle of justice in migration, would nevertheless be hard to justify.
