In addition to the final declaration, both the United States and Iran have published more detailed descriptions of their agreement. Officials on both sides acknowledge that they have different stories about this project.  The U.S. government has released a fact sheet summarizing the main points of the agreement.  Shortly after its publication, Iranian leaders, including Iran`s supreme leader and Iran`s defence minister, challenged the document on important issues that have not yet been resolved.    Iranian officials accused the government of acting in bad faith and claimed that the United States violated the agreement by sowing doubts about its commitment to the agreement and preventing economic benefits to Iran. U.S. officials have discouraged foreign governments and companies from negotiating with Iran or investing in Iran, said Secretary of State Mohammad Javad Zarif, and the U.S. Treasury under Trump has not authorized the sale of planes or spare parts to Iran.
In July 2015, conservative right-wing activist Larry Klayman filed a complaint against Obama and members of Congress in federal court in West Palm Beach, Florida, saying the agreement should be seen as a treaty requiring Senate ratification.   Klayman`s appeal was dismissed in September 2015 for failure to apply.  A body known as the Joint Commission, made up of representatives of all parties to the negotiations, oversees the implementation of the agreement. Under the chairmanship of Federica Mogherini, the EU`s foreign policy chief, it is responsible for dispute resolution and the vote of a majority of its members can allow IAEA inspectors to access unreported websites they consider suspicious. The panel also oversees the transmission of nuclear or dual-use materials. On September 10, the day before the vote, Boehner threatened to use “any instrument at our disposal to stop, slow down and delay the full implementation of this agreement,” saying that a complaint filed by Republicans in the House against the president (which stated that the Iran Nuclear Review Agreement Act was not respected) “is an option that is very possible.”   Four months later, House Republicans abandoned their plans to sue the government over the JCPOA.  Negotiations focused on restrictions on Iran`s main nuclear facilities: the heavy water reactor and the production facility of Arak IR-40 (which was under construction but was never commissioned, as Iran had agreed under the November 2013 Joint Action Plan (Interim Agreement) not to commission or power the reactor; the Bushehr nuclear power plant; the Gachin uranium mine; the Fuel Fordow enrichment plan; the unit conversion of uranium to isfahan; Natanz uranium enrichment plant; and the Parchin Military Research and Development Complex.  Iran began phasing out the agreement in May 2019.
