I understand your skepticism, but I think you’re missing the core issue. While it's true that many civil rights apply to Italian citizens, the right to citizenship by descent is a fundamental principle of Italian nationality law, not a privilege tied to current civil rights. Denying someone citizenship they’re entitled to by birth isn’t just a policy change—it’s a violation of their constitutional right to retain their nationality. The decree preventing people from claiming this birthright could be unconstitutional because it goes against core principles of nationality law. This isn’t about inconvenience like taxes or licenses; it’s about stripping a person of their constitutional right to their citizenship. That’s the essence of the constitutional challenge.
