"It would be invidious of me to try to summarize the content of the book, given the breadth and detail into which the author has gone. I can only commend this book as a reference guide to all those States affected by the law of the sea which, as the author points out by her examples, includes all States, both cobusbastal and landlocked." - Richard Haworth, School of Public Administration, Dalhousie University"The interesting contribution of this particular book is that it explores whether other states (apart from the state with the extended continental shelf) have a right to be involved in the whole process of determining whether such state has an extended continental shelf. […] the book is an interesting read and an important contribution to the literature on the continental shelf beyond 200 nautical miles." - Edwin Egede, School of Law and Politics, Cardiff University"With the detailed and deep discussion of the role of judicial institutions, the author believes that, 'If the potential of judicial institutions is fully realized, they can play an instrumental role in ensuring the compliance and enforcement of international law, thereby ensuring a rule-based system of maritime security governance'...Therefore, this book is “proposing coordinated efforts by all States for the operationalization of judicial institutions for the common goal of combating maritime terrorism." - Yin Yang, Law School, Sun Yat-sen University

"It would be invidious of me to try to summarize the content of the book, given the breadth and detail into which the author has gone. I can only commend this book as a reference guide to all those States affected by the law of the sea which, as the author points out by her examples, includes all States, both cobusbastal and landlocked." - Richard Haworth, School of Public Administration, Dalhousie University"The interesting contribution of this particular book is that it explores whether other states (apart from the state with the extended continental shelf) have a right to be involved in the whole process of determining whether such state has an extended continental shelf. […] the book is an interesting read and an important contribution to the literature on the continental shelf beyond 200 nautical miles." - Edwin Egede, School of Law and Politics, Cardiff University"With the detailed and deep discussion of the role of judicial institutions, the author believes that, 'If the potential of judicial institutions is fully realized, they can play an instrumental role in ensuring the compliance and enforcement of international law, thereby ensuring a rule-based system of maritime security governance'...Therefore, this book is “proposing coordinated efforts by all States for the operationalization of judicial institutions for the common goal of combating maritime terrorism." - Yin Yang, Law School, Sun Yat-sen University
