ng system of science of the constitutional law: 1) concept of object, sources and system of the Soviet constitutional law as the field and science; 2) the Soviet Constitution, its basic principles and role in communist system; 3) The Soviet state power is embodiment of sovereignty of people; 4) State power and basic rights and freedoms of citizens; 5) Political system of the USSR is embodiment of sovereignty of nations; 6) Organization of Soviet state power and basic forms of activity of its bodies [13]. Specific approach offered by the authors, supposed that none of blocks of the science system textually reproduced the structure of the working at that period Constitution of the USSR. there appeared other variants of exposition of the system of science of constitutional law, which characteristic feature was walking away from the traditional for 1930-1950th transference of the system of science of the constitutional law structure of the working at that period Constitution [14]. It was caused by a number of factors. First, constitutionally-legal reality was changing, and that should be reflected in the system of its research. Second, science became more free in realization of the creative potential. Third, the idea about the necessity of adopting of the new constitution was realized in the society. adopting of the Constitution of the USSR of +1977 and the Constitution of Ukraine of 1 978 the views on the system of science of the constitutional (state) law were largely liberalized. Except for recognition of necessity of scientific researches in the field of general theory of constitutional law, history of Soviet constitutions, history of science of constitutional law, its methodology, etc., there appear the long-time researches of forms of socialistic democracy, Soviet right to vote, constitutionally-legal status of prosecutor s office, bodies of justice, legal status of the union republics. For the first time perspective is recognized such direction of scientific researches, as legal status of local councils of people s deputies, and the centre of research of this problematic are officially recognized scientific establishments of the Ukrainian SSR. During the last years of existence of the former USSR the system of science of the Soviet constitutional law was at high-level development: new perspective directions of scientific researches developed, proof and authoritative centres of scientific researches were formed, the results of scientific researches were incarnated not only in numerous textbooks, monographs and scientific articles, and in law-making activity of the Supreme Soviet of the USSR and the Supreme Soviet of the Ukrainian SSR. changes in public and state system connected first of all with disintegration of the USSR and change of public system, entailed reformation of constitutional law as the field of law, regulating relations of the power and its interrelation with a person and a citizen. Changes in the law entailed change of ideas in science, update of category of staff, change of priorities and accents. Human rights, constitutionalism in understanding of western democracy and presented as common to all mankind values ??became new ideological guide line for constitutional law for the majority of the former soviet states, including Ukraine. spite of huge prospects of development of science of constitutional law on the modern stage of development of the society and state, the problem of its system on the whole did not get the due realization. Both in Ukrainian and Russian editions these questions are not arisen [15] or are examined extremely fragmentarily [16]. In modern constitutionally-legal science the monograph of NA Bogdanova differs from the rest. [17], and in the educational editions there can be selected separate works in which the question about the system of science of the constitutional law is covered more or less thoroughly only [18]. s consider separate approaches to understanding of structure of the system of science of constitutional law. , The Russian scientists, M.P. Avdeenkov and Yu.A. Dmitriev, consider that each element of the system of the field must precede its scientific-theoretical research. Proceeding from this, they offer seeing of the system of science of constitutional law, the constituents of which are: 1) the theory of constitutional law (subject, method, constitutionally-legal norms and legal relations, sources of constitutional law, constitutionally-legal responsibility); 2) the theory of the Constitution; 3) naturally-legal and socially-legal doctrine of development of human rights; 4) the theory of peoples, national and state sovereignty; 5) the study about the form of rule and division of powers; 6) the theory of political-territorial organization of the State power; 7) the theory and classification of the political modes; 8) the theory of people s representative office; 9) the study about the civil society; 10) the concepti...
