Treaty of Amity, Economic Relations and Consular Rights

The Treaty of Amity, Economic Relations and Consular Rights between the United States and Iran was signed in Tehran on August 15, 1955, received the consent of the U.S. Senate on July 11, 1956 and entered into force on 16 June 1957. The treaty is registered by the United States to the United Nations on 20 December 1957. The official texts are in English and Persian. It is sealed by plenipotentiaries Selden Chapin (U.S.) and Mostafa Samiy (Iran). The Treaty has served as the jurisdictional basis for various international legal disputes between the United States and Iran, including the International Court of Justice (ICJ) cases Oil Platforms and Alleged Violations of the 1955 Treaty of Amity, Economic Relations and Consular Rights. In October 2018, the United States provided notice that it would be withdrawing from the Treaty following Iran's use of the Treaty as a basis to challenge the U.S. imposition of sanctions under the Joint Comprehensive Plan of Action (JCPOA) in the Alleged Violations case.
