Critical Reflections on the International Humanitarian Law Aspects of the ICJ Wall Advisory Opinion

I shall confine my brief thoughts on the recent advisory opinion of the International Court of Justice (ICJ) on the legal consequences of the construction of a wall in the occupied Palestinian territory (OPT) to the Court’s treatment of international humanitarian law (IHL) in general, and to the law of belligerent occupation in particular. To that end, I will focus on the following four areas: the Court’s consideration of the applicable law as regards IHL; the Court’s interpretation of Article 6 of the 1949 Geneva Convention Relative to the Protection of Civilian Persons in Time of War; the Court’s consideration of the concept of military necessity in the context of foreign military occupation; and the Court’s consideration of the responsibility of third states, particularly the high contracting parties to the Fourth Geneva Convention, for violations of relevant principles of IHL by an occupying power.
