The Constitution of Iraq is the fundamental law of Iraq. The first constitution came into force in 1925. The current constitution was drafted and approved in 2005. Iraq is an Islamic democracy.
Iraq's first constitution, which established a constitutional monarchy, entered into force under the auspices of a British military occupation in 1925 and remained in effect until the 1958 revolution established a republic. Interim constitutions were adopted in 1958, 1963, 1964, 1968, and 1970, the last remaining in effect de jure until the Transitional Administrative Law was adopted. In 1990, a draft constitution was prepared but never promulgated due to the onset of the Gulf War.
The current constitution was approved by a referendum that took place on 15 October 2005. The constitution was drafted in 2005 by members of the Iraqi Constitution Drafting Committee to replace the Law of Administration for the State of Iraq for the Transitional Period (the "TAL"). The TAL was drafted between December 2003 and March 2004 by the Iraqi Governing Council, an appointed body that was selected by the Coalition Provisional Authority after the Iraq War and occupation of Iraq by the United States and Coalition forces.
Under a compromise brokered before the referendum, it was agreed that the first parliament that was to be elected pursuant to the new constitution would institute a Constitutional Review Committee with a view to determine whether the constitution should be amended. Any amendments agreed would have to be ratified by a similar referendum to the one that originally approved it. After this agreement was entered into, the Sunni-majority Iraqi Islamic Party agreed to back a Yes vote in the referendum that took place on October 15, 2005. The Constitutional Review Committee was constituted by the Iraqi parliament on 25 September 2006. 
Electoral Commission officials said at a news conference that 78 percent of voters backed the charter and 21 percent opposed it. Of the 18 provinces, two recorded "No" votes greater than two thirds, one province short of a veto. A two-thirds rejection vote in three of the country's 18 provinces (of which three—Mosul, Anbar, and Salahaddin—are thought to include Sunni majorities) would have required the dissolution of the Assembly, fresh elections, and the recommencement of the entire drafting process. Turnout in the referendum was 63 percent, commission officials had previously said.
The drafting and adoption of the new Constitution was not without controversy, however, as sectarian tensions in Iraq figured heavily in the process. The chairman of the drafting committee, Humam Hamoudi, regularly made statements which were interpreted as meaning that there would be no compromises on Sunni demands. The deadline for the conclusion of drafting was extended on four occasions because of the lack of consensus on religious language. In the end, only three of the 15 Sunni members of the drafting committee attended the signing ceremony, and none of them signed it. Sunni leaders were split as to whether to support the constitution. Saleh al-Mutlaq, the chief Sunni negotiator, urged followers of his Hewar Front to vote against it, but the biggest Sunni block, the Iraqi Accord Front did support the document after receiving promises that it would be reviewed and amended, taking into account their views. A Constitution Amendment Committee has been set up in this regard, but the progress has been slow. Notably, the same figure who chaired the drafting committee, Humam Hamoudi, is chairing the amendment committee as well.
The text of the proposed constitution was read to the National Assembly on Sunday 28 August 2005. It describes the state as a "democratic, federal, representative republic" (art. 1) (however, the division of powers is to be deferred until the first parliament convenes), and a "multi-ethnic, multi-religious and multi-sect country" (art. 3).
The Transitional National Assembly, which was elected in January 2005 pursuant to the Coalition Provisional Authority's Transitional Administrative Law, appointed a Constitutional Committee for the purpose of preparing a draft constitution by August 15, 2005. The Committee was initially made up of 55 members, all of whom were drawn from the Transitional National Assembly, but its membership was eventually expanded beyond the Assembly's numbers, in order to allow representatives from the Sunni Arab community to participate (given that the latter had boycotted the elections that gave rise to the Transitional National Assembly).
According to the Transitional Administrative Law, the Constitutional Committee was obliged to complete its work by 15 August 2005, and for the draft to be submitted to a referendum by 15 October 2005. However, by the beginning of August 2005, all parties were in agreement that a final agreement on some of the Constitution's most important elements, including federalism, was still far from complete. As a result, the Committee was effectively dissolved and replaced by an ad hoc body (referred to as the "Leadership Council"), which was composed of approximately 6 members and which continued to negotiate the constitution's final terms until three days before the referendum date.
The Constitution was adopted on 15 October 2005 in a referendum of the people.
Under a compromise brokered before the referendum, it was agreed that the first parliament that was to be elected pursuant to the new constitution would institute a Constitutional Review Committee with a view to determine whether the constitution should be amended. Any amendments agreed would have to be ratified by a similar referendum to the one that originally approved it. After this agreement was entered into, the Sunni-majority Iraqi Islamic Party agreed to back a Yes vote in the referendum that took place on 15 October 2005. The Constitutional Review Committee was constituted by the Iraqi parliament on 25 September 2006. 
On 18 September 2005, several changes to the text of the constitution were approved by Iraq's parliament, and will be included in the version published for ratification by the public. Also, a new compromise was made which caused many Sunni groups to support the constitution. Many of the links to the Constitution use the 24 August 2005 AP wire translation; however, the American Chronicle uses a slightly different translation dated 12 October 2005.
The Constitution sets out a multitude of basic assertions (unfortunately because of last minute changes to the constitution, most of the footnote references below to specific articles in the constitution are inaccurate):
Rights and freedoms
The Constitution defines many rights and freedoms, and incorporates laws in many subject areas into the Constitution. It guarantees the rule of law, equality before the law, equal opportunity, privacy, inalienable nationality and dual nationality, judicial independence, the prohibition on criminal ex post facto laws, right to counsel, a public trial unless the court decides to make it a secret trial, a presumption of innocence, the right to participate in public affairs and the right to vote, to elect and to nominate, freedom from extradition, political asylum, "economic, social and cultural liberties", the right to work, the right to join trade unions, ownership of personal property, eminent domain powers, rights similar to the Four Freedoms (European Union), minimum wage, universal health care, free education, dignity, freedom from psychological and physical torture and inhumane treatment and the right to compensation, freedom from "compulsory service", limited freedom of expression, freedom of the press, and freedom of assembly, the right to engage in sports, limited freedom of forming and of joining associations and political parties, requirement of warrants for wiretaps, freedom of religion, freedom of thought, conscience and belief.
The Federal Government
The federal government is composed of the executive, legislative, and judicial branches, as well as numerous independent commissions.
The legislative branch is composed of the Council of Representatives and the Federation Council.
Council of Representatives
The Council of Representatives is the main elected body of Iraq. The Constitution defines the "number of members at a ratio of one representative per 100,000 Iraqi persons representing the entire Iraqi people." The members are elected for terms of 4 years.
The council elects the President of Iraq; approves the appointment of the members of the Federal Court of Cassation, the Chief Public Prosecutor, and the President of Judicial Oversight Commission on proposal by the Higher Juridical Council; and approves the appointment of the Army Chief of Staff, his assistants and those of the rank of division commanders and above, and the director of the intelligence service, on proposal by the Cabinet.
The Federation Council is composed of representatives from the regions and the governorates that are not organized in a region. The council is regulated in law by the Council of Representatives.
The executive branch is composed of the President and the Council of Ministers.
The President of the Republic is the head of state and "safeguards the commitment to the Constitution and the preservation of Iraq's independence, sovereignty, unity, the security of its territories in accordance with the provisions of the Constitution." The President is elected by the Council of Representatives by a two-thirds majority, and is limited to two four-year terms. The President ratifies treaties and laws passed by the Council of Representatives, issues pardons on the recommendation of the Prime Minister, and performs the "duty of the Higher Command of the armed forces for ceremonial and honorary purposes."
There also exists a Vice President which shall assume the office of the President in case of his absence or removal.
The Presidency Council is an entity currently operating under the auspices of the "transitional provisions" of the Constitution. According to the Constitution, the Presidency Council functions in the role of the President until one successive term after the Constitution is ratified and a government is seated.
Council of Ministers
The Council of Ministers is composed of the Prime Minister and his cabinet. The President of Iraq names the nominee of the Council of Representatives bloc with the largest number to form the Cabinet. The Prime Minister is the direct executive authority responsible for the general policy of the State and the commander-in-chief of the armed forces, directs the Council of Ministers, and presides over its meetings and has the right to dismiss the Ministers on the consent of the Council of Representatives.
The cabinet is responsible for overseeing their respective ministries, proposing laws, preparing the budget, negotiating and signing international agreements and treaties, and appointing undersecretaries, ambassadors, the Chief of Staff of the Armed Forces and his assistants, Division Commanders or higher, the Director of the National Intelligence Service, and heads of security institutions.
The federal judiciary is composed of the Higher Judicial Council, the Supreme Court, the Court of Cassation, the Public Prosecution Department, the Judiciary Oversight Commission, and other federal courts that are regulated by law. One such court is the Central Criminal Court.
Higher Judicial Council
The Higher Judicial Council manages and supervises the affairs of the federal judiciary. It oversees the affairs of the various judicial committees, nominates the Chief Justice and members of the Court of Cassation, the Chief Public Prosecutor, and the Chief Justice of the Judiciary Oversight Commission, and drafts the budget of the judiciary.
The Supreme Court is an independent judicial body that interprets the constitution and determines the constitutionality of laws and regulations. It acts as a final court of appeals, settles disputes amongst or between the federal government and the regions and governorates, municipalities, and local administrations, and settles accusations directed against the President, the Prime Minister and the Ministers. It also ratifies the final results of the general elections for the Council of Representatives.
Central Criminal Court
The Central Criminal Court of Iraq is the main criminal court of Iraq. The CCCI is based on an inquisitorial system and consists of two chambers: an investigative court, and a criminal court.
Independent commissions and institutions
The Independent High Commission for Human Rights, the Independent Electoral High Commission, and the Commission on Public Integrity are independent commissions subject to monitoring by the Council of Representatives. The Central Bank of Iraq, the Board of Supreme Audit, the Communications and Media Commission, and the Endowment Commission are financially and administratively independent institutions. The Foundation of Martyrs is attached to the Council of Ministers. The Federal Public Service Council regulates the affairs of the federal public service, including appointment and promotion.
Powers of the Federal Government
The federal government has exclusive power over:
Powers shared with regional authorities:
All powers not exclusively granted to the federal government are powers of the regions and governorates that are not organized in a region. Priority is given to regional law in case of conflict between other powers shared between the federal government and regional governments.
Chapter Five, Authorities of the Regions, describes the form of Iraq's federation. It begins by stating that the republic's federal system is made up of the capital, regions, decentralized provinces, and local administrations.
The country's future Regions are to be established from its current 18 governorates (or provinces). Any single province, or group of provinces, is entitled to request that it be recognized as a region, with such a request being made by either two-thirds of the members of the provincial councils in the provinces involved or by one-tenth of the registered voters in the province(s) in question.
Provinces that are unwilling or unable to join a region still enjoy enough autonomy and resources to enable them to manage their own internal affairs according to the principle of administrative decentralization. With the two parties' approval, federal government responsibilities may be delegated to the provinces, or vice versa. These decentralized provinces are headed by Provincial Governors, elected by Provincial Councils. The administrative levels within a province are defined, in descending order, as districts, counties and villages.
Article 120 states that Baghdad is the Capital of the Republic, within the boundaries of Baghdad Governorate. The constitution makes no specific reference to the status of the capital and its surrounding governorate within the federal structure, stating merely that its status is to be regulated by law.
Consisting solely of Article 121, Part Four simply states that the constitution guarantees the administrative, political, cultural, and educational rights of the country's various ethnic groups (Turkmens, Assyrians, etc.), and that legislation will be adopted to regulate those rights.
