This paper examines the challenge to fairness and justice in the enforcement of international anti-doping laws, focusing on differential enforcement by global regulatory bodies such as WADA and CAS. Through two case studies this paper illustrates that both the enforcement of relevant laws and the decision-making of judicial authorities have been interfered by external factors. Despite the presence of established frameworks like the World Anti-Doping Code, inconsistencies in enforcement undermine the integrity of anti-doping efforts, and raise questions about external factors that impair the fairness and consistency of international anti-doping laws.
