Politics
The politics of Iran takes place in the framework of a republic with Islamist Ideology. The December 1979 constitution (and its 1989 amendment) define the political, economic and social order of the Islamic Republic of Iran. It declares that Shi'a Islam of the Jaafari (Usuli) school of thought is Iran's official religion.
Iran is a founding member of the United Nations organisation and also a member of the Organization of the Islamic Conference and the Non-Aligned Movement. The political system of the Islamic Republic is based on the 1979 Constitution called the 'Qanun-e Asasi' ('Fundamental Law'). The system comprises several intricately connected governing bodies.
The Supreme Leader
The Supreme Leader of Iran is responsible for the delineation and supervision of 'the general policies of the Islamic Republic of Iran'. The Supreme Leader is Commander-in-Chief of the armed forces, controls the military intelligence and security operations; and has the only power to declare war. The heads of the judiciary, state radio and television networks, the commanders of the police and military forces and six of the twelve members of the Council of Guardians are appointed by the Supreme Leader. The Assembly of Experts elects and dismisses the Supreme Leader on the basis of qualifications and popular esteem - none have ever been dismissed. The Assembly of Experts is responsible for supervising the Supreme Leader in the performance of legal duties.
Executive Branch
The Constitution defines the President as the highest state authority after the Supreme Leader. The President is elected by universal suffrage, by those 15 years old and older, for a term of four years. Presidential candidates must be approved by the Council of Guardians prior to running. The President is responsible for the implementation of the Constitution and for the exercise of executive powers, except for matters directly related to the Supreme Leader. The President appoints and supervises the Council of Ministers, coordinates government decisions, and selects government policies to be placed before the legislature.
Currently, 10 Vice-Presidents serve under the President, as well as a cabinet of 21 ministers, who must all be approved by the legislature. Unlike many other states, the executive branch in Iran does not control the armed forces.
Although the President appoints the Ministers of Intelligence and Defence, it is customary for the President to obtain explicit approval from the Supreme Leader for these two ministers before presenting them to the legislature for a vote of confidence.
Legislative Branch
The current legislature of Iran is the unicameral. Before the Islamic Revolution, the legislature was bicameral, but upper house was removed in the new constitution.
Majles (Parliament)
Majles-e Shura-ye Eslami (Islamic Consultative Assembly), comprising 290 members elected for four-year terms. The Majlis drafts legislation, ratifies international treaties, and approves the national budget. All Majlis candidates and all legislation from the assembly must be approved by the Council of Guardians.
Guardian Council
The Guardian Council is comprised of 12 jurists, including six clerics appointed by the Supreme Leader, and six jurists elected by the Majlis from among the Muslim jurists nominated by the Head of the Judicial System. The Council interprets the constitution and may reject bills from parliament deemed incompatible with the constitution or Sharia (Islamic law). These are referred back to parliament for revision. In a controversial exercise of its authority, the Council has drawn upon a narrow interpretation of Iran's constitution to veto parliamentary candidates.
Expediency Council
The Expediency Council has the authority to mediate disputes between Majles and the Council of Guardians, and serves as an advisory body to the Supreme Leader, making it one of the most powerful governing bodies in the country.
Judicial Branch
The Supreme Leader appoints the head of the Judiciary, who in turn appoints the head of the Supreme Court and the chief public prosecutor. There are several types of courts including public courts that deal with civil and criminal cases, and 'revolutionary courts' that deal with certain categories of offences, including crimes against national security. The decisions of the revolutionary courts are final and cannot be appealed.
The Special Clerical Court handles crimes allegedly committed by clerics, although it has also taken on cases involving lay people. The Special Clerical Court functions independently of the regular judicial framework and is accountable only to the Supreme Leader. The Court's rulings are final and cannot be appealed.
Assembly of Experts
The Assembly of Experts, which meets for at least two days, twice annually, comprises 86 'virtuous and learned' clerics elected by adult suffrage for eight-year terms. Based on the laws approved by the first Assembly, the Council of Guardians has to determine candidates' ijtihad eligibility using written examination. The Assembly elects the Supreme Leader and has the constitutional authority to remove the Supreme Leader from power at any time. As all of their meetings and notes are strictly confidential, the Assembly has never been known to challenge any of the Supreme Leader's decisions.
Military
The Islamic Republic of Iran has two kinds of armed forces: the regular forces and the Islamic Revolutionary Guards Corps (IRGC), totalling about 545,000 personnel. Both fall under the command of the Ministry of Defence and Armed Forces Logistics.
The regular armed forces has an estimated 420,000 troops in three branches: Ground Forces (350,000); Navy (18,000) and Air Force (52,000).
The Islamic Revolutionary Guards Corps has an estimated 125,000 personnel in five branches: Qods Force (Special Forces), Basij (Paramilitary), Navy, Air Force, and the Ground Forces.
Iran also has a paramilitary volunteer force called the Basij, which includes about 90,000 full-time, active-duty uniformed Basij members, up to 300,000 reservists, and a further 11 million men and women who could be mobilised (largest number of troop mobilisation in the world).
Human Rights
Iranian history boasts the first charter of human rights; the Persian Empire (Iran) established unprecedented principles of human rights in the 6th century BC. Since then, the status of human rights in Iran has varied dramatically. Today, the violation of human rights by the Islamic Republic of Iran continues to be significant, despite many efforts by Iranian human right activists, writers, NGOs and some political parties. Human rights in Iran regularly faces the issues of governmental impunity, restricted freedom of speech, and gender inequality.
According to Human Rights Watch, respect for human rights in Iran, especially freedom of expression and opinion, deteriorated considerably in 2005. The government routinely uses torture and ill-treatment in detention, including prolonged solitary confinement, to punish dissidents. The judiciary, which is accountable to Supreme Leader Ali Khamenei, has been at the centre of many serious human rights violations.
