Post-national plurality not only puts items on the global map of law that had no place in the black-box model of Legal Positivism: instances of non-state law, such as transnational, indigenous, and religious law. Post-national law also fundamentally alters the relations among instances of law, and annuls the self-sufficiency and reciprocal closure of the black boxes. The black-box model depicted the plurality of law as simple diversity, as mere coexistence of state legal orders, without any hint of either dialogical or conflictual relations. In contrast, post-national plurality invites us to conceive of the global constellation of law as interlegality where instances of law overlap and communicate in various modes.
