‘Undeserving’ individuals and what does it tell us about the statelessness legal framework?

There is a category of ’undeserving’ persons who are excluded from the mechanisms of prevention, protection and reduction of statelessness. They can be deprived of nationality and such action is not per se arbitrary and contrary to international law. Further, they may be excluded from protection as per Article 1 (2) (iii) of the 1954 Convention relating to the Status of Stateless Persons. Finally, their access to naturalization procedures (reduction) may barred when deemed to pose threats to public security or having criminal history; this is also non-controversial under international law. ‘Undeserving’ may not only be adults posing threat to public security but also minors, whose parents for example committed a fraud in naturalization procedures. What is the basis for singling out such a category of persons? Do securitarian considerations only undermine the consensus that statelessness is mala in se, as suggested by C. Batchelor, or is it already off?
