Washington, DC: IOS Press. pp. 187–192. ISBN978-1614996507. "Russia’s 2014 military intervention breached [Ukraine’s titles to sovereignty, territorial integrity and inviolability of its borders] de facto, but the Minsk armistice formalises that breach at the international level. Under the armistice, a formal restoration of Ukraine’s sovereignty and control of the external border in Donetsk-Luhansk is no longer a matter of title, right, or international law. Instead, that restoration becomes conditional on enshrining the Donetsk-Luhansk proto-state in Ukraine’s constitution and legitimising the Moscow-installed authorities there through elections. Moreover, the terms of that restoration are negotiable between Kyiv and Donetsk-Luhansk (i.e., Moscow) under the Minsk armistice."
