The relationship between international humanitarian law and asset freeze obligations under United Nations sanctions

Abstract

AbstractWhile challenges may persist with respect to the relationship between counterterrorism (CT) and humanitarian action, it is at least understood that CT measures must comply with international humanitarian law (IHL). Clarifying the relationship between this body of law and CT measures is one of the modest but important innovations of United Nations (UN) Security Council Resolution 2462. At a minimum, references to IHL in this resolution leave a pathway for States to take measures to preserve impartial humanitarian action from the effects of CT, and at most, they prescribe that States should take such measures. Progress in clarifying the relationship between UN sanctions obligations and IHL obligations appears to be lacking with respect to non-CT-related UN sanctions. As will be discussed in this paper, this leads to questions regarding the application of the so-called “supremacy clause” contained in Article 103 of the UN Charter vis-à-vis IHL obligations.
