ABSTRACT
The term “migrations” interpreted as a phenomenon with an indeterminate and infinitely complex content, which is made up of the sum of different events and situations, that can be deconstructed and categorized in different ways, may be classified and challenged alternatively under one of the two aforementioned perspectives with very different results, both with respect to the legal characterization, on the one side, and to the subsequent policy determinations, on the other. The “sanction” of the expulsion of illegal migrants from the territory of arrival entails, under a juridical standpoint, the even formal denial of their identity of identifiable person. Forced migrations impose their presence to the public opinion and in international politics because of their mass dimensions as a plague disrupting not only foreign populations, forced to flee their countries of origin, but the whole international community as well.
