Judgment 238/2014 of the Italian Constitutional Court reopens the debate on the extent of the immunity enjoyed by states for violations of jus cogens. The decision, which questions the authority of the ICJ's 2012 judgment in Germany v Italy, could certainly have effects on the formation of customary international law. In addition, it revives the discussion on the relationship between national and international law and on the supremacy of the latter over the former, especially if read in light of the previous Medellin and Kadi I decisions. Judgment 238/2014 is an opportunity to reappraise the role played by international law in domestic courts, particularly in cases where international law conflicts with core domestic constitutional values.
