This book examines the concept of nationality of means of transportation in terms of jurisdiction in international law. It reassesses the definition of nationality and explores how it is conferred. The book first places nationality in the broader perspective of jurisdiction in international law, and examines the historical development and necessity of the nationality of means of transportation. It goes on to investigate whether and under which conditions international organizations may confer a 'nationality' on means of transportation, examining the law of the sea conventions and air and space treaties. The book finally explores several questions relating to international registration of means of transportation, building a regime of international registration. Vincent Cogliati-Bantz introduces a necessary distinction between transport internationally registered and transport registered in a State but fulfilling a mission for an international organization. As a work that proposes the ability for international organisations to access international spaces without reliance on State-registered means of transport, this book will be of great use and interest to scholars and students of public international law, international organisations, and maritime, space, and aviation law.
