This article takes the continuing applicability of human rights law as an accepted and welcome starting point, and proceeds to lay out some of the challenges and obstacles encountered during the joint application of IHL and Human Rights Law, that still need to be addressed. These include extra-territorial applicability of human rights law; the mandate and expertise of human rights bodies; terminological and conceptual differences between the bodies of law; particular difficulties raised in non-international armed conflicts; and the question of economic, social and cultural rights during armed conflict.
