On 6 March 2014, the Parliament of Crimea announced its decision to secede from Ukraine and join the Russian Federation. The Ukrainian government and the international community condemn Crimean’s secession as illegitimate and illegal according to the international law. Nonetheless, Crimea claimed that in its legitimate action of breaking away from Ukraine, it has followed the Kosovan precendence of the latter’s secession from Serbia in 2008. Utilizing Remedial Rights Only, this master’s thesis purpose is to examine the grounds on which secession can be justified. Furthermore, by comparing the two cases accordingly, namely Kosovo and Crimea, the research tries to examine the precedence value of Kosovo’s secession in that of Crimea’s. The research has found out that Kosovo’s secession is an act of legitimate secession, while that of Crimea is not; therefore, as a matter of course, the Kosovo’s case is not a valid precedence for the Crimean separation from Ukraine.
