This addition to the Elements of International Law series explores the role of international law as an integral part of the Russian legal system, with particular reference to the role of international treaties and of generally-recognized principles and norms of international law. Following a discussion of the historical place of treaties in Russian legal history and the sources of the Russian law of treaties, the book strikes new ground in exploring contemporary treaty-making in the Russian Federation by drawing upon sources not believed to have been previously used in Russian or western doctrinal writings. Special attention is devoted to investment protection treaties. The importance of publishing treaties as a condition of their application by Russian courts is explored. For the first time a detailed account is given of the constitutional history of treaty ratification in Russia, the outcome being that present constitutional practice is inconsistent with the drafting history of the relevant constitutional provisions.The volume gives attention to the role of the Russian Supreme Court in developing treaty practice through the issuance of "guiding documents" binding on lower courts, the reaction of the Russian Constitutional Court to judgments of the European Court of Human Rights, and the place of treaties as an integral part of the Russian legal system. Butler further explores the hierarchy of sources of law, together with other facets of Russian arbitral and judicial practice with respect to treaties and other sources of international law. He concludes with a consideration of the 'generally-recognized principles and norms of international law' and their role as part of the Russian system.
