Techniques and methods of civil law research on the contract system legislation

Introduction: the problem of compatibility of the multibranch norms contained in the com-plex contract system legislation is actually not researched in the doctrine. With few exceptions, scientists’ attention is focused on the analysis and criticizing of the separate civil legal aspects. A significant number of works are based on commenting the old and new contract legislation, with the conceptual issues being left unaddressed. Purpose: to justify the necessity for the complex ap-proach to the contract relations regulation; to analyze the correlation between the special and general legislation on contract conclusion and performance. Methods: the system method of cog-nition, as well as the methods of complex and interdisciplinary analysis and the method of com-parative legal study were used. Results: the contract system legislation is complex, thus providing for two approaches associated with the differentiation and integration of all the types of the exis-ting legal knowledge about the contract system. The absence of a strong concept of the contract system legislation results in failure to provide the consistency of legal regulation and in excessive detailing and duplication of the rules of special laws in the Civil Code of the Russian Federation. The interdisciplinary researches are of special importance, as for understanding the civil legal aspects of the contract system it is apparently not enough to only use formal-logic analysis of the existing legal norms. The financial budget aspect present within the contract system legal regula-tion makes it essential to research the correlation between the civil, budget and special legislation in terms of the efficiency of regulating the government purchases of goods, works and services. The orientation towards acceding to the World Trade Organization Agreement on Government Procurement demands successive and simple regulation in this sphere.
