Unveiling the “Legal Conscience of the Civilized World:” a Critical Look at the Institut de Droit International

Abstract

For the past 150 years, the Institut de Droit International (IDI) has held a prominent position in the field of international law, garnering recognition as one of the world's distinguished professional organizations for international lawyers. Yet, a closer look at its structures reveals that in fact, the IDI has been and remains an elitist club, comprised of renowned international legal jurists, practitioners, and scholars. Its goal was and is to formulate “principles from which rules [of international law] could be deduced.”1 While there may be doubts regarding the contemporary authority of the IDI in shaping today's international law, it possessed significant influence during its first century of existence. Therefore, on the occasion of its 150th anniversary, this essay offers an alternative perspective on the IDI's contribution to the field, focusing on the implications of its claimed status of the “legal conscience of the civilized world” and exploring whether this status had somehow impacted international legal norms and principles. While further empirical investigation is required to establish a definitive correlation between the IDI's affiliations with the “civilized world” and a skewed focus of international law on Western legal traditions, a few examples can serve as a starting point. The illustrations from the IDI's engagement with the laws of war—specifically, the nineteenth-century regulation of occupation and the post-World War II determination of military targets—exemplify how the inherent elitism rooted in the notion of “civilization” can be discerned in pivotal advancements of international law.
