Life In Iran

After the Supreme Leader, the Constitution defines the President of Iran as the highest state authority. The President is elected by universal suffrage for a term of four years and can only be re-elected for one term. Presidential candidates must be approved by the Guardian Council prior to running in order to ensure their allegiance to the ideals of the Islamic revolution.
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, who has the final say in all matters. The President appoints and supervises the Council of Ministers, coordinates government decisions, and selects government policies to be placed before the legislature. Eight Vice-Presidents serve under the President, as well as a cabinet of twenty two 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 Defense, 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. Iran's current president, Mahmoud Ahmadinejad, was first elected in a run-off poll in the 2005 presidential elections and re-elected in the 2009 presidential elections.
As of 2012, the legislature of Iran (known in English as the Islamic Consultative Assembly) is a unicameral body. Before the Iranian Revolution, the legislature was bicameral, but the upper house was removed under the new constitution. The Majlis of Iran comprises 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 Guardian Council.
The Guardian Council comprises twelve jurists including six appointed by the Supreme Leader. The others are elected by the Parliament from among the jurists nominated by the Head of the Judiciary. The Council interprets the constitution and may veto Parliament. If a law is deemed incompatible with the constitution or Sharia (Islamic law), it is 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. The Expediency Council has the authority to mediate disputes between Parliament and the Guardian Council, and serves as an advisory body to the Supreme Leader, making it one of the most powerful governing bodies in the country.
