<![CDATA[The principle of strict liability in the World Anti-Doping Code (WADC) holds athletes responsible for the presence of prohibited substances in their bodies without requiring proof of fault as the basis for determining an anti-doping violation. The application of this principle is crucial for maintaining the integrity, fairness, and credibility of sports, but at the same time raises issues when implemented within the national sports legal system. This study aims to analyze the harmonization of the principle of strict liability in the WADC with the sports legal system in Indonesia and to identify forms of disharmony that still exist in its regulations. This study employs a normative legal research method using a statutory approach, a conceptual approach, and a case-based approach, by analyzing relevant primary and secondary legal sources. The results of the study indicate that substantive and institutional harmonization has been achieved through Indonesia’s commitment to international anti-doping standards, the ratification of the 2005 UNESCO International Convention Against Doping in Sport, and the existence of the Indonesia Anti-Doping Organization (IADO) in the implementation of WADC standards. However, regulatory harmonization has not been comprehensively achieved because national regulations do not yet explicitly address the principle of strict liability, standards of proof, mechanisms for athlete defense, and the consequences of anti-doping violations as outlined in the WADC system. This situation highlights the need to strengthen national regulations so that the application of strict liability ensures legal certainty and legitimacy while continuing to provide proportional protection for athletes.]]>
