In the article, a concept of delocalization of international commercial arbitration is considered, and it is argued that this concept is groundless. The question is posed as to whether international commercial arbitration awards form part of national legal systems. It is further argued that extending an arbitration award beyond the boundaries of national legal systems inevitably results in the fragmentation of legal regulation, undermines the stability of civil commerce and predictability of legal framework, and leaves no room for discussion on mutual prejudicial effect of court judgments and arbitration awards.
