Abstract
What moral claims do undocumented immigrants have to membership? Joseph Carens has argued that illegal migrants with long-term residence have a claim to national membership because they already are de facto members of local communities. This article builds on the linkage between illegality, residence, and rights, but shifts the focus from the migrant to the state, and from membership-based arguments to the rule of law. I argue that the rule of law, as expressed in the principle of legal certainty, provides an alternative justification for the regularization of resident undocumented migrants. The principle of legal certainty recognizes the right of individuals to make long-term plans for their lives by requiring that state action be reasonably predictable and nonarbitrary. Thus, as an expression of legal certainty, both civil and criminal codes have statutes of limitation that place a time limit beyond which most crimes and misdemeanors can no longer be prosecuted, and individuals can move on with their lives. Not only do these statutes recognize the individual’s right to be free from arbitrary state control, they also demand that the state cut its losses and accept the consequences of its failure to act in a timely manner. I contend that, in the absence of a statute of limitation on illegal entry, the deportation of settled migrants constitutes an arbitrary act of state power. The article explores a number of judicial rulings to illustrate the argument’s normative logic.
