Jus Cogens vs. State Immunity, Round Two: The Decision of the European Court of Human Rights in the Kalogeropoulou et al. v. Greece and Germany Decision

On 12 December 2002, the European Court of Human Rights (ECHR) declared inadmissible an application filed against Greece and Germany by 257 victims and relatives of victims of Nazi war crimes committed in Greece in 1944. This decision was not only the latest of a number of ECHR decisions concerning the judicial treatment of Nazi war crimes committed during the Second World War, but it also marked the second time that the Court had to deal with the question of whether states may rely on sovereign immunity in cases concerning breaches of peremptory and non-derogable jus cogens norms.
