Implementing the Right of Return Is an Obligation Owed by a State to All Other States Under the law of nationality, the duty to implement the individual’s right of return is an obligation owed by a state to all other states. The rule is that states are required to readmit (i.e., allow to exercise their right of return) their own nationals - including temporarily displaced persons in cases of state succession - because to refuse to do so would impose on some other state a resulting obligation to receive, or to host, the rejected individual. This principle is known as the “rule of readmission.” The rule rests upon the premise that a state may not choose to reject, or leave stranded, a national outside its borders by refusing readmission because such an action would impose an unacceptable corresponding burden upon another (receiving) state to accept the stranded individual. Under international law, states may not burden each other in this way. The Prohibition against (Mass) Denationalization There exists another customary (binding) rule under the law of nationality known as the “prohibition against denationalization.” This rule follows as a natural corollary to the rule of readmission, already discussed above. The prohibition against denationalization prevents a state from using revocation of nationality status (i.e., denationalization) as a means of avoiding its obligation to admit its own nationals. This rule – like the rule of readmission, which is its “sister” rule in the law of nationality – had attained customary status well before the events of 1948. The prohibition against denationalization exists in an authoritative draft international convention dating from 1930[20], various regional declarations (such as the 1986 Strasbourg Declaration on the Right to Leave and Return), in resolutions by UN organs[21], and numerous respected commentators have written of the prohibition against denationalization as a binding norm of customary law since as early as 1927. The entry for “Population, Expulsion and Transfer” in the authoritative Encyclopedia of Public International Law puts the rule categorically, stating that nationals may not be denied re-admission on the rationale that they are no longer nationals. Denationalization is prohibited under international law in the case of a single instance affecting a single person. The prohibition against denationalization is therefore much stronger when denationalization is implemented on a mass scale and is intended by the government so acting, to cast out a whole large class of nationals from the body politic of the state. Israel’s 1952 Nationality Law (for “non-Jews”) completely violates the rule of the law of nationality prohibiting denationalization. While the 1952 Nationality Law carefully avoids the use of the term “non-Jew” in describing the narrowly defined[22] categories of persons who might be eligible for Israeli citizenship thereunder, it was clearly intended to apply to non-Jews only because Jews would obviously avail themselves of the easier terms and procedures under the Law of Return (for Jews).[23] The vast majority of Palestinian refugees are factually incapable
