The WTO Agreement does not determine whether WTO norms have direct effect in the domestic legal systems of WTO Members. The chapter explores this issue as to the Russian legal system. The author examines the jurisprudence of Russian domestic courts and shows their approach as to provisions of WTO law. The chapter also addresses the Treaty on the Functioning of the [Eurasian] Customs Union in the Framework of the Multilateral Trading System, which provides for a special role for WTO norms in the EAEU legal system.
