In this EUDO CITIZENSHIP Forum Debate, several authors consider the interrelations between eligibility criteria for participation in independence referendum (that may result in the creation of a new independent state) and the determination of putative citizenship ab initio (on day one) of such a state. The kick-off contribution argues for resemblance of an independence referendum franchise and of the initial determination of the citizenry, critically appraising the incongruence between the franchise for the 18 September 2014 Scottish independence referendum, and the blueprint for Scottish citizenship ab initio put forward by the Scottish Government in its 'Scotland's Future' White Paper. Contributors to this debate come from divergent disciplines (law, political science, sociology, philosophy). They reflect on and contest the above claims, both generally and in relation to regional settings including (in addition to Scotland) Catalonia/Spain, Flanders/Belgium, Quebec/Canada, Post-Yugoslavia and Puerto-Rico/USA.
