It seems intuitively correct – perhaps even obvious – that if we think of the nation-state as the institution of a democratic people, then states have the ‘right to exclude’. That is, states have a moral right to stop would-be immigrants from entering because a self-determining people have the right to decide on their own membership practices. Yet states often act without securing the will of the people, and we do not normally think that this compromises the independence of the citizens. Think, for instance, of decisions like diplomatic appointments, strategic military deployments, or complex fiscal policies. These are all routine decisions that shape the future of the country, but citizens are excluded from the decision-making process.
This is puzzling, because if states can act without being directed by citizens and without compromising self-determination, then self-determination cannot be a claim about states being directed by the will of citizens. If this is correct, then the self-determination justification for the right to exclude is doubtful because self-determination does not require that citizens determine state policies. As I argue in a recent article, this includes immigration policies.
