Present and future economic, technological and societal changes and evolutions fundamentally affect traditional legal structures of the territorial state system. They increasingly call for global approaches and solutions, transgressing the tools of classical public international law. This trilingual series publishes monographs, studies and collected papers dedicated to these challenges. The contributions examine existing instruments, in particular within the framework of the international trading system. They explore new approaches and search for innovative solutions within the global process of legal integration. Research efforts are dedicated to different walks of life and areas of regulation, and to the quest for adequate constitutional structures of transnational and democratic processes.
