The book by B.R. Tuzmuhamedov is a rare, possibly the only one edition in Russia in the genre of a reader in this sphere of international law. The book is very proficiently written and is very successful as it was sold out fast. The basis of the reader is formed by the special course taught by the Professor B.R. Tuzmuhamedov for several years. The advantage of the course is that the author simultaneously combines his research and educational activity with practical work in the sphere. The most interesting and valuable are the chapters of the reader devoted to the development of the system of the constitutional supervision in Russia, evolution of the approaches of the Russian Constitutional Court to international legal sources. In the reader there is offered a wide range of works of international jurists of the past and present. But there is a possibility to widen the list of authors included in the reader as the reviewer points out. In the conclusion the reviewer welcomes the appearance of such an important and necessary book and offers other scholars to create readers similar to that of Professor B.R. Tuzmuhamedov.
