Ius Filiationis: A defence of Citizenship by Descent

Abstract

Costica Dumbrava runs three main attacks against ius sanguinis: It is tainted by its associations with ethnonationalism; it is inadequate because, in an age of new reproduction technologies, same sex marriage and patchwork families, biological descent no longer traces social parenthood; and it is unnecessary, since its protective effects can be achieved by other means. I will accept the first and second argument with some modifications, but reject the third.
