Rafael Munagorri (university of Nantes) has posted Droit international privé et hiérarchie des normes: Observations sur une rencontre (Private Law and Hierarchy of Norms: Some Remarks on Their Relations) on SSRN.
Traditional methods to solve conflicts of laws and conflict of jurisdictions have been shaped without the idea of the hierarchy of norms. Moreover, some specialists of international private law consider that the very idea of hierarchy of norms is inappropriate within their field. This opinion reflects an ideological point of view. Hierarchy of norms is interesting in order to understand historical, theoretical and epistemological dimensions of international private law.
