Since the first Asian Law and Society Conference (ALSA) was held at the National University of Singapore (NUS) in 2016, a number of special sessions have been organized to focus on the deconstruction of the Westphalian transnational order based on the concept of the “nation-state.”1 This dominant hegemony was predicated on the congruence of the geo-territorial boundaries of both the state and the nation, as well as the “assumed integration” of state-defined “citizenship” and another distinctly layered “membership” based on culture, ethnic, religious, and indigenous affiliations. The “nation-state” ideology has thus masked a history of tensions and conflicts, often manifested in the form of oppression, persecution, and genocide directed at the nation and its peoples by the state and its predatory institutions. Our studies have shown that such conflicts between the nation and the state have been observed in multiple regions in Asia, including Kashmir in India; Moro and Islamic communities of Mindanao in the Philippines; Karen, Kachin, and other autonomous nations in Myanmar; West Papua, Aceh, Kalimantan, South Moluccas, Minahasa, and Riau in Indonesia; Kurds in multiple state systems of Iraq, Syria, Turkey, and Iran; and Palestine in Israel, among many other culturally autonomous nucleated communities in Asia and across the world.2 The phrase “the nation and the state” was specifically chosen to distinguish and highlight the unique conflictual histories of two geo-political entities and to provide a fundamentally differing interpretation of history, geography, the role of law, and global affairs from the perspectives of nation peoples, rather than from that of the state or international organizations, as traditional analyses do. The Westphalian “nation-state” hegemony led to the inviolability of the state’s sovereign control over the nation and peoples within a state-delimited territory. The state then began to engage in another predatory project: to strengthen and extend its international influence over other states and, thus, the nations within these states, by adopting new constitutional provisions to offer cross-border “citizenship” to diasporic “ethnic-nationals” and descendants of “ex-migrants” who now inhabit foreign states. The nations have similarly capitalized on constitutional activism by erecting their own Constitutions to explore collaboration with other nations, as well as diasporic populations of their own, in order to carve out a path toward the nations’ independence within, and even beyond, the respective state systems. The “constitutional” activism sought by the state and the nation has become an important political vehicle with which to engage in possible collaboration with diasporic “ethno-nationals” and ex-migrant communities, in order to further assert political influence and strengthen trans-border politics of the state and the nation. Three articles included in this issue investigate such constitutional activism of cross-border politics and transnational collaborations in Asia, the Americas, Europe, and other regions across the globe.
