When Kosovo declared independence, in February 2008, it was stated that the move was not an act of self-determination. Instead, the key states that supported the decision insisted that the case for statehood arose from a unique set of circumstances. Kosovo was not a precedent; it was a sui generis case in international politics. This essay considers the arguments underpinning this claim to exclusivity and argues that, taken either individually or collectively, the main justifications used to support Kosovo's ‘unique’ statehood—such as the abuse of human rights—in fact have serious consequences for other separatist conflicts elsewhere.
