The passage below discusses competing theories of customary international law. For each of the designated referential phrases used by the author, identify the specific concept, action, or relationship that serves as its functional antecedent within the text.

The traditional framework of customary international law (CIL) rests upon the dual pillars of consistent state practice and *opinio juris*—the belief that such practice is legally mandated. Historically, jurists posited that sovereign states are bound only by rules to which they have consented, a principle that ostensibly shields domestic authority from external overreach. However, the modern proliferation of multilateral treaties and declarations by international bodies has challenged this voluntarist conception. Some scholars argue that these declarations, even when technically nonbinding, crystallize into binding CIL much more rapidly than traditional state practice would allow. This acceleration—often termed 'instant custom'—bypasses the protracted historical accretion of consistent state actions.

Critics of instant custom contend that equating General Assembly resolutions with actual state practice effectively dilutes the foundational consent requirement. They warn that such a methodological shift allows a numerical majority of states to dictate normative frameworks to dissenters. This imposition, they argue, not only infringes upon state sovereignty but also undermines the democratic legitimacy of international law, which traditionally relied on explicit ratification processes by individual nations.

In defense of modern CIL formation, proponents maintain that the rapid articulation of norms is essential to address urgent global crises, which cannot wait for decades of uniform state practice. They posit that collective declarations in international fora represent a more immediate expression of the global conscience. The tension between the traditional and modern approaches reveals a deeper jurisprudential schism regarding the fundamental purpose of international law: whether it serves primarily to regulate the interactions of independent sovereigns or to advance a substantive global public order. Resolving this dialectic requires a nuanced approach that reconciles the imperative for agile norm creation with the enduring necessity of sovereign consent.
