Revocation, Suspension and Termination of ‎Unilateral Acts of States in International Law

While the legal validity of unilateral acts of states has been subject to various challenges, in the actual practice of states such acts have long existed as regards their daily ordinary relations, so much so that the development of customary international relations regarding them can be examined. Unilateral acts matter both as a common way by which states operate in international relations, and as a recognized source of law in scholarship and jurisprudence. This paper, in a descriptive-analytical way and using library resources, examines the situations in which the practice of the state leads to the termination or revocation of unilateral act. Thus, the question is under what preconditions are states able to end or withdraw their unilateral action? Based on the comparison between the legal effects of unilateral acts with those of treaty obligations, it could be argued that the right to revoke such acts may be subject to the consent of beneficiary third parties. Nonetheless, the International Law Commission’s approach of merely imitating the rules of treaty law on this subject seems problematic.
