Some consider that a state has a responsibility not to recognize as a state any entity that has attained the qualifications for statehood by a violation of basic principles of the UN Charter: the UN Security Council has in several instances (Resolution 216 (1965) and Resolution 217 (1965), concerning Rhodesia; Resolution 541 (1983), concerning Northern Cyprus; and Resolution 787 (1992), concerning the Republika Srpska) issued Chapter VII resolutions (binding in international law) that denied their statehood and precluded recognition. In the 2010 International Court of Justice advisory opinion on Kosovo's declaration of independence, the ICJ ruled that "general international law contains no applicable prohibition of declarations of independence." The Court carefully noted "that in all of those instances the Security Council was making a determination as regards the concrete situation existing at the time that those declarations of independence were made; the illegality attached to the declarations of independence thus stemmed not from the unilateral character of these declarations as such, but from the fact that they were, or would have been, connected with the unlawful use of force or other egregious violations of norms of general international law, in particular, those of a peremptory character (jus cogens). In the context of Kosovo, the Security Council has never taken this position. The exceptional character of the resolutions enumerated above appears to the Court to confirm that no general prohibition against unilateral declarations of independence may be inferred from the practice of the Security Council."
