Abstract

Problems have plagued the ius sanguinis principle – the transmission of citizenship from parent to child – for as long as it has existed. Costica Dumbrava is surely correct that the time has come to ask whether ius sanguinis is still necessary. But the core problem with ius sanguinis, I would argue, is not that it uses the parent-child relationship to determine membership but that it overemphasizes the importance of the genetic tie to this relationship.
