To Blockade or Not To Blockade? The Legal Status of Russia's Suspension of Shipping in the Sea of Azov

Abstract

This article explores the legal situation relating to the Sea of Azov in the light of the Russian suspension of shipping on 24 February 2022. While this act received little scholarly or political attention, there is a debate concerning the legality of the suspension of shipping, mainly whether it is governed by the law of naval blockade under the laws of naval warfare. The article analyses the situation from the perspectives of both international humanitarian law (IHL) and the law of the sea (LOS) and examines how the interaction between the two legal regimes affects the analysis. The article supports the conclusion that the Russian conduct does not constitute a naval blockade but may be an accepted practice within the legal regime of naval warfare. In addition, it holds that LOS affects both the laws of naval warfare and the status of the Sea of Azov. Furthermore, the article raises doubts as to the relevance and applicability of the legal concept of naval blockade in modern international law.
