Various kinds of disputes may arise between the players, associations, coaches or owners of the team from a local to an international level. The institutions like the United Nations (UN), International Olympic Committee (IOC), World Anti- Doping Agency (WADA) and Court of Arbitration for Sport (CAS) are the cornerstones of international sports law. These may include disputes between the adjudicating body and the players, contract between the players and the leagues or quasi-criminal acts like betting, gambling, match-fixing, etc.
