Currently, taking into account the new circumstances in which the economy operates, greater importance is attached to such an economic association as the Eurasian Economic Union. The article analyzes one of the areas of authority vested in the Commission — the sphere of competition policy, since the Commission considers applications, conducts investigations, considers cases of violation of competition rules, sends appropriate requests for information to consider cases of violation of competition rules, if a violation or signs of a violation have been committed on the cross-border market of the Union. But who exercises control and supervisory functions over the activities of this body and should there be such control and supervision? This article will be devoted to these issues, which require analysis taking into account the scientific approach and law enforcement. The author analyzes the powers of the Eurasian Economic Commission in the field of competition policy. Reveals such gaps in Union law as the lack of a mechanism for challenging determinations of refusal to initiate proceedings on violation of competition rules and other powers of the Eurasian Economic Commission.
