Though the concept of Global Administrative Law has been one of the most popular subjects in international literature on international law, it has been largely ignored in Turkish academia barring few papers on the issue. It has been mainly used to describe a huge area of global relations mainly deemed outside the conventional operational area of international law. However, there seems to be no unified understanding of this term amounts to. There is a number of thinkers defending the employment of this very term whereas some others take a stance in favour of a broader understanding of the term international law with a view to also covering these emerging relations. One of the most ideal areas of operation for a global administrative law is lex sportiva. In this specialized domain, IOC and WADA function as if they are administration within the confines of an administrative law. One striking example for these activities is the WADA Decision on Russia, which foresaw the banning of this country from all major sport events for a period of four years. In this paper, the authors aim to probe into global administrative law and the nature of WADA decisions.
