Brunk & Hakimi: The Prohibition of Annexations and the Foundations of Modern International Law

Ingrid (Wuerth) Brunk (Vanderbilt Univ. - Law) & Monica Hakimi (Columbia Univ. - Law) have posted The Prohibition of Annexations and the Foundations of Modern International Law (American Journal of International Law, forthcoming). Here's the abstract:

The international legal norm that prohibits forcible annexations of territory is foundational to modern international law. It lies at the core of three projects that have been central to the enterprise. The first focuses on settling title to territory as the basis for establishing state authority. The second regulates the use of force across (settled) territorial borders. The third provides for the people within each state’s (settled) borders collectively to determine their own fates. The norm that prohibits forcible annexations is integral to each of these projects independently, and by tying them together, has had a transformative effect on the legal system as a whole.

However, this prohibition is also misunderstood, both as a matter of history and in its relationship to other contemporary international legal norms. Because it is intertwined with all three of the above projects, its origins cannot be traced to only one or the other. The common narrative that describes it as the inevitable outgrowth of regulating war is, therefore, misleading and incomplete. That narrative overlooks the role that formerly colonized states played in securing this norm while seeking to establish themselves as states, through decolonization and claims of self-determination. In modern doctrine, too, the prohibition of annexations is often subsumed into the general prohibition on the use of force, when in fact, its normative influence extends much more broadly.

As a result, the norm’s significance and position in modern international law are consistently overlooked. Analysts have also, by and large, failed to appreciate that it is now caught up in a broader contest over the future world order and at risk of erosion. As deeply flawed as the previous world order was, jettisoning this norm is a dangerous path forward. From Ukraine to Palestine, Israel, the Nagorno-Karabakh region, the Golan Heights, Western Sahara, and the Chagos Archipelago, states and nonstate actors alike care deeply about exercising power over territory, which has historically been a primary impetus of interstate war.
