[…] The manner in which the Flemish federated entity in Belgium incorporates the World Anti-Doping Agency’s norms represents an instructive case study to formulate a tentative response to this research question. The World Anti-Doping Agency is an example of a global hybrid actor that was founded and continues to exist through the partnership between governments and private (sports) organizations. The article first shows that national legislation may be a necessary method to transpose hybrid global norms in the national legal order. Second – out of at least three techniques to adopt legislation (reception, delegation and dynamic referral) – the latter technique could represent the compromise between efficiency and constitutionality. However, the dynamic referral technique is equally limited by constitutional law and the European Convention on Human Rights. The article concludes with a number of recommendations for national legislatures or executives when they refer dynamically to hybrid global norms as a technique of modern public lawmaking.
