In The Contentious and Advisory Jurisdiction of the International Tribunal for the Law of the Sea, Miguel Garc a Garc a-Revillo offers an in-depth examination of all relevant facets of the jurisdiction of this important international judicial institution. Created by the United Nations Convention on the Law of the Sea, ITLOS plays an essential role not only in respect to the interpretation of this major international treaty but also to the contemporary law of the sea in general. The book covers both the contentious (ratione materiae, ratione personae, mainline, incidental, compulsory, not compulsory) and the advisory jurisdiction of ITLOS, which are analysed not only from a theoretical perspective but also in light of the own Tribunal's jurisprudence.
