Regulating Stateless Vessels: A Jurisdictional Dilemma in the Law of the Sea

Abstract

The absence of a clear legal framework governing stateless vessels on the high seas poses a significant threat to maritime safety and security. These vessels, which operate without a flag or nationality, fall outside the traditional regulatory structure of flag state jurisdiction, leading to complex legal, jurisdictional, and enforcement challenges. The 1982 United Nations Convention on the Law of the Sea (UNCLOS), a cornerstone of maritime law, offers limited guidance on the regulation of stateless vessels, resulting in inconsistent state practices and jurisdictional uncertainties. This article analyses the legal ambiguities surrounding stateless vessels, particularly concerning the exercise of jurisdiction, examining the competing theories of jurisdiction, namely the ‘any state theory’ and the ‘nexus state theory.’ It argues for the adoption of the ‘any state theory’ to close the jurisdictional gap and ensure maritime order, thereby preventing stateless vessels from operating with impunity. The findings of this analysis highlight the urgent need for a robust and coherent legal framework to address the operation of stateless vessels and its impact on the international legal system. The study emphasizes the importance of establishing clear rules and mechanisms to prevent illicit activities such as drug trafficking, migrant smuggling, and illegal, unreported, and unregulated (IUU) fishing, and to ensure accountability on the high seas. Ultimately, this article underscores the necessity of upholding the integrity of the law of the sea through enhanced international cooperation and the development of effective measures to govern stateless vessels.
