The aim of this paper is to offer a broad characterization of the kind of account that I believe cannot plausibly face conclusively the problem of the ethics of immigration restrictions in a non-ideal world at the level of the constitutional essentials. I argue that justice-based accounts of immigration controls fail to normatively evaluate what immigration controls do to outsiders subjected to them in non-ideal conditions, so judgments of justice by themselves tend to be overall bad for the interest of (...) immigrants. I explain this by insisting that a prior question about the legitimacy of immigration controls have been overlooked by familiar accounts. A full account of the ethics of immigration suitable for guiding constitutional essentials should be able to connect distinct kinds of justice-based evaluations in order to ask both, what legitimacy requires from territorial institutional control as well as what justice requires from immigration policy.

Many conservatives endorse a defence of closed borders grounded in basic liberal rights such as the basic right of association. Some conservatives also endorse libertarian principles of legitimacy. It is not clear though that this sort of defence of closed borders is somehow coherent with these libertarian ideals. I argue that conservative libertarians of this kind must reject this defence of closed borders because either it collapses into a form of statism incoherent with libertarian principles of legitimacy, or into an (...) ideal precept without appeal regarding reality in the here and now that could only be applied to changing the very nature of the societies we know. As a result, at least conservative libertarians need to find a different source of justification for closed borders. (shrink)
