摘要:The Russian competition law does not include the definition of the concept of collective dominance, and the notion of this institution itself contains many gaps. The indicated disadvantages of statutory regulation and simplified approaches of the Federal Antimonopoly Service, which became possible due to the formal approach, have led to the formation of controversial law enforcement practice by the antimonopoly authority and courts. The article presents the analysis of legal regulation, as well as the law enforcement practice, and proposition on solutions to the stated problems.
