Norme internazionali generali e principi costituzionali fondamentali, fra giudice comune e giudice costituzionale

In this brief article the following ideas are advanced: a) in the italian legal order the costitutional assessment concerns directly rules, not provisions; b) customary international rules are directly identified and applied by (italian) judges; c) customary international rules can be directly subject to a constitutional assessment; c) in the "State immunity case", such an assessment could lead the Italian Constitutional Court to declare the unconstitutionality of the customary rule on State immuniry - in cases of war crimes or crimes against humanity - rather than declaring ill-founded the question of constitutionality of the norm “created in our legal order by the incorporation, by virtue of Article 10, para. 1 of the Constitution”, of the customary international law of immunity of States from the civil jurisdiction of other States, raised in relation to Articles 2 and 24 of the Constitution; d) some positive consequences could stem by such a different approach, both from the point of view of the legal predictability of the effects of the constitutional assessment and from that one of the relationships between ordinary and constitutional jurisdictions .
