Arbitrators of the CAS use relative freedom in decisionmaking, carrying out the actual rule-making, suggesting the international and national sports organizations to be guided by "stare decisis" (to stand on solved) or even by "binding precedents" (binding precedents) in the course of law-enforcement activity. But not each of the decisions of the arbitration will have one of the named above statuses - this is due to the essence of the dispute under consideration, when it is necessary to present an interpretation of a specific rule, to propose a methodology for determining the intentions of the subject of sports, to demonstrate a reading of the fundamental principle of law or the content of the lex sportiva principle. Thus, when it is required to apply the rules of WADA acts that include fairness provisions, the arbitrator in a particular situation may create a rule for the application of the concept, thereby formulating the content of "fairness."
