The Mandatory Nature of International Maritime Organization Conventions and the Principle of Tacit Acceptance in International Law

Abstract

International maritime and shipping law heavily relies on legal instruments developed to regulate the global maritime industry, primarily through conventions and resolutions adopted by the International Maritime Organization (IMO). Their binding nature is crucial for maintaining maritime order, ensuring safety at sea, environmental protection, and promoting interstate cooperation. This article critically analyses the “Tacit Acceptance” procedure—a key mechanism within the IMO—designed to address the dynamic needs of global maritime governance. Under this procedure, treaty amendments automatically enter into force unless explicitly rejected by member States within a defined period. The paper explores its relevance and growing importance in modern maritime transport.
