United States Diplomatic and Consular Staff in Tehran (United States of America v. Iran)

Overview of the case by the International Court of Justice:

The case was brought before the Court by Application by the United States following the occupation of its Embassy in Tehran by Iranian militants on 4 November 1979, and the capture and holding as hostages of its diplomatic and consular staff. On a request by the United States for the indication of provisional measures, the Court held that there was no more fundamental prerequisite for relations between States than the inviolability of diplomatic envoys and embassies, and it indicated provisional measures for ensuring the immediate restoration to the United States of the Embassy premises and the release of the hostages.

In its decision on the merits of the case, at a time when the situation complained of still persisted, the Court, in its Judgment of 24 May 1980, found that Iran had violated and was still violating obligations owed by it to the United States under conventions in force between the two countries and rules of general international law, that the violation of these obligations engaged its responsibility, and that the Iranian Government was bound to secure the immediate release of the hostages, to restore the Embassy premises, and to make reparation for the injury caused to the United States Government. The Court reaffirmed the cardinal importance of the principles of international law governing diplomatic and consular relations.

It pointed out that while, during the events of 4 November 1979, the conduct of militants could not be directly attributed to the Iranian State — for lack of sufficient information — that State had however done nothing to prevent the attack, stop it before it reached its completion or oblige the militants to withdraw from the premises and release the hostages. The Court noted that, after 4 November 1979, certain organs of the Iranian State had endorsed the acts complained of and decided to perpetuate them, so that those acts were transformed into acts of the Iranian State.

The Court gave judgment, notwithstanding the absence of the Iranian Government and after rejecting the reasons put forward by Iran in two communications addressed to the Court in support of its assertion that the Court could not and should not entertain the case. The Court was not called upon to deliver a further judgment on the reparation for the injury caused to the United States Government since, by Order of 12 May 1981, the case was removed from the List following discontinuance.
