Stergiopoulos v. Iran: Italian Supreme Court of Cassation Decision on Human Rights Limitations on Sovereign Immunity in International Law and Italian Constitutional Law

In Angela Stergiopoulos v. Iran, the Italian Supreme Court of Cassation held that state immunity does not bar exequatur proceedings against a foreign state when those proceedings seek the recognition and enforcement of a foreign judicial decision finding the state responsible for serious breaches of human rights.
