On 30 November 2010, the International Court of Justice issued its decision in the merits phase of the Ahmadou Sadio Diallo case. This decision turned on the questions of whether the DRC had violated Mr Diallo's human rights and his rights as a shareholder and manager in two corporations he owned in the DRC. This paper analyses the decision of the Court in the light of the choices it made and the methodology it applied, and demonstrates that both issues raise fundamental questions. The Court's decision on Mr Diallo's human rights is often ambitious to the detriment of clarity, whereas the part of the judgment dealing with corporate rights does not seem to move beyond its 1970 predecessor in Barcelona Traction. While understandable, this is also regrettable and the consequences for individuals doing business and/or residing in foreign countries may be substantial.
