II. INTERNATIONAL COURT OF JUSTICE, CASE CONCERNING AHMADOU SADIO DIALLO (REPUBLIC OF GUINEA V DEMOCRATIC REPUBLIC OF THE CONGO) JUDGEMENT OF 30 NOVEMBER 2010

Abstract

This is the first time in its history, to the best of my knowledge, that the International Court of Justice has established violations of the two human rights treaties at issue, together, namely, at universal level, the 1966 UN Covenant on Civil and Political Rights and, at regional level, the 1981 African Charter on Human and Peoples' Rights, both in the framework of the universality of human rights.This is the opening paragraph of Judge Cançado Trindade's Separate Opinion in the Diallo case. The ICJ's judgment is a remarkable decision contributing to the widening and deepening of international law and has consequences for several fundamental questions, including the role of the ICJ and international law in making human rights effective, erga omnes and jus cogens rules, customary law, evidence, and several substantive rules. In bringing the transformation of international law one step further, the Diallo judgment develops the ICJ as ‘the principal judicial organ of the United Nations’1 at the top of an open international law system. To achieve this, the Court had to overcome a series of jurisdictional and procedural hurdles.2 All the permanent judges of the ICJ agreed that Congo had violated the prohibition on arbitrary detention and expulsion and that the violations gave rise to a right of compensation. The ICJ's use of sources from other international and regional bodies as sources of authority, indicates solutions to fragmentation problems.
