Who observed that International Law is the vanishing point of jurisprudence?

The observation that "International Law is the vanishing point of jurisprudence" is attributed to the legal scholar H.L.A. Hart. He suggested that the complexities and ambiguities of international law challenge traditional legal theories and frameworks, leading to debates about its status and effectiveness compared to domestic law. This perspective highlights the difficulties in enforcing international norms and the often fragmented nature of international legal systems.
