Why focus on sources traditionally dubbed “exogenous” or “non-economic” in the context of the debate about international law’s increasing fragmentation? Simply put, understanding interactions between different normative orders (or orders that are characterized as different) is essential to understanding the way in which courts and tribunals contribute to the production and reproduction of the international legal order. Among other approaches, critical systems theory has been used to defend the claim that international law is replete with systemic biases of various kinds that are rendered invisible through hegemonic discourses.
