On 22 April 1980, during the hostage crisis in the American Embassy in Tehran, the
EU imposed sanctions against Iran for violating the laws of diplomatic immunity. The
EU acted after the Soviet Union vetoed a resolution in the
UN Security Council that sought to impose sanctions on Iran. It justified its act by saying “the situation created a concern for the whole international community.” If the
EU could then act without express authorisation from the Security Council, it could surely do so today. Victor Kattan reports.
