Rights practices in South Korea are cosmopolitanizing and have rich implications for the future of Global Constitutionalism, for its further development as a truly global project. Not having a regional human rights system, but with active participation by global-minded rights-holders, the South Korean Constitutional Court serves as a venue where international human rights law interacts with constitutional law in dynamic ways. The last few years observed the Korean Court playing a leadership role in regional constitutionalist projects of promoting human rights and democracy, which reflects the Court‘s evolving transnational self-identity. Asian and national tradition and culture continue to be challenged through constitutional rights review processes, accommodating both the locality of contexts and the universality of rights norms. The recent development in South Korea exemplifies a practice of bottom-up and locally grown Global Constitutionalism emerging outside the West.
