Retroactivity in international treaty law

Abstract

Problem setting. Due to the fact that the constitutional norms determine the status of an international treaty, the binding nature of which has been approved by the parliament as part of national legislation, it is important to study the temporal effect of international treaties, namely their retroactivity. In general, the Vienna Convention contains a provision according to which an international treaty has no retroactive effect in respect of the States which are parties to it, except where the intention to give retroactive effect to the treaty follows from the treaty itself or the agreements of its parties. These exceptions to the general rule indicate the non-absoluteness of the latter, so it is appropriate to study the factors that determine the existence of retroactive agreements, as well as controversial and controversial issues that arise in this regard. Analysis of recent researches and publications. Scholars such as S.N. Ivanov, RA Kalamkaryan, M.A. Kapustina, II Lukashuk, OV Pushnyak and others. However, this area needs further study and analysis, given the existence of exceptions to the general provision on the lack of retroactive effect of international agreements. Target of research. Тo consider the conditions under which an international treaty has retroactive effect, to investigate the factors influencing the decision to grant retroactive effect and the issues arising in connection with the retroactivity of international treaties. Article’s main body. This study examines the non-absoluteness of the provision on the absence of retroactive effect of international agreements. Among the reasons that encourage states to anticipate retroactive effect – the interpretive or additional nature of the international agreement or the need to resolve the situation that arose before its conclusion. It should be emphasized that some agreements have retroactive effect by virtue of their object, which provides this retroactive effect, as agreed by the parties, although not explicitly stated in the contract. It is also not uncommon for certain rights and obligations to arise not because of an international treaty that has not yet entered into force, but because of customary norms that are enshrined in it. Conclusions and prospects for the development. The principle of no retroactive effect of an international agreement is not absolute. In each case, the reasons for the application of retroactivity must be decided by a judicial authority in the process of interpreting the contractual obligations. An important role in the possibility of retroactive application of an international treaty is played by its object or the co-existing customary norms of international law and the principles recognized by civilized nations as binding.
