With Judgment No. 21995/2019 (the Judgment), the Italian Court of Cassation (Court of Cassation) once again tackled the limits of sovereign immunity with regard to crimes against humanity (para. 7). The Judgment is part of litigation originating in Greece with the Leivadia Tribunal's 1997 Distomo decision, confirmed in 2000 by the Areopago (Hellenic Supreme Court), which ordered Germany to pay compensation and legal costs of approximately 50 million euros to the relatives of 218 victims of the Distomo massacre committed by the German military in 1944. In this Judgment, the Court of Cassation addressed whether sovereign immunity blocked the seizure of German assets located in Italy as part of that compensation order. The Court of Cassation's decision is noteworthy because it takes the discussion on sovereign immunity from jurisdiction and crimes against humanity one step further by addressing, in particular, the question of compensation and attachment of claims and rights held by the debtor against third parties.

In August 2012, the First Criminal Division of the Court of Cassation (Supreme Court or Court), the highest Italian domestic court, issued a judgment upholding Germany’s sovereign immunity from civil claims brought by Italian war crime victims against Paul Albers and eight others in the Italian courts (Albers). In so doing, the Court overruled its own earlier decisions and also reversed the judgment of April 20, 2011, by the Italian Military Court of Appeal (Military Court), which had upheld such claims relating to war crimes committed by German forces in Italy during World War II. With this ruling, the Court of Cassation put an end to its decade long effort to find an exception to the well-known rule of customary international law providing for sovereign immunity from foreign civil jurisdiction for acts jure imperii. This revirement resulted from the Court’s decision to give effect to the judgment of the International Court of Justice (ICJ) in Germany v. Italy.
