This book is devoted to an examination of the legal status of govern ment merchant ships while on the high seas or in the waters of foreign states in time of peace. The object of this examination is to ascertain whether there is any rule of international law which accords such a ship a higher status than that of private merchant ships. Whether government merchant ships, unlike private ships, are entitled to certain immunities from the jurisdiction of foreign states is the question that we have set out to answer in this book. A discussion of the rules concerning the nationality of such a ship or the jurisdiction of the flag state over her does not find a place in this work. A government merchant ship may be defined as a merchant ship l owned or operated by a state. Immunity of a ship here means the exemption of a government ship from the jurisdiction of any state other than the flag state. This term also connotes the immunity of the flag state from the jurisdiction of the tribunals of foreign states in respect of proceedings connected with such a ship. Immunity of persons means the exemption of persons in the service of a govern ment ship, or other persons on board her, from the jurisdiction of any state other than the flag state.

This book examines the concept of port state jurisdiction in the context of international maritime law. In particular the book focuses on situations where port states have used their jurisdiction over visiting foreign-flagged vessels to apply unilateral domestic law, as compared with the internationally-agreed standards enforced by regional port state control organisations. To illustrate the legal issues involved three recent pieces of legislation are analysed in detail: the United States' Cruise Vessel Security and Safety Act 2010, the EU's liability insurance directive of 2009, and Australia's Fair Work Act 2009. Key issues include the legality of port states’ attempts to regulate aspects of a vessel’s structure or equipment, or even certain activities that may take place before a vessel’s arrival in port. The author argues that examples of unilateral measures being imposed by way of port state jurisdiction are growing, and that without active protests from flag states this concept will continue to expand in scope. As international law currently presents very few restrictions on the actions of ambitious port states, such developments may have a significant impact on the future of international maritime regulation.​
