The 550-member Parliament carries out legislative functions. Election is by the D'Hondt system of party-list proportional representation. To participate in the distribution of seats, a party must obtain at least 10% of the votes cast at the national level as well as a percentage of votes in the contested district according to a complex formula. The president enacts laws passed by Parliament within 15 days. With the exception of budgetary laws, the president may return a law to the Parliament for reconsideration. If Parliament reenacts the law, it is binding, although the president may then apply to the Constitutional Court for a reversal of the law. Constitutional amendments pass with a 60% vote, but require a popular referendum unless passed with a two-thirds majority; the president may also submit amendments passed with a two-thirds majority to a popular referendum.

The judiciary is declared to be independent, but the need for judicial reform and confirmation of its independence are subjects of open debate. Internationally recognized human rights, including freedom of thought, expression, assembly, and travel, are officially enshrined in the Constitution but have at times been narrowly interpreted, can be limited in times of emergency and cannot be used to violate what the Constitution and the courts consider the integrity of the state or to impose a system of government based on religion, ethnicity, or the domination of one social class. The Constitution prohibits torture or ill treatment; the current government has focused on ensuring that practice matches principle. Labor rights, including the right to strike, are recognized in the Constitution but can be restricted.

The high court system includes a Constitutional Court responsible for judicial review of legislation, a Court of Cassation (or Supreme Court of Appeals), a Council of State serving as the high administrative and appeals court, a Court of Accounts, and a Military Court of Appeals. The High Council of Judges and Prosecutors, appointed by the president, supervises the judiciary.

In the November 2002 election of Turkey's 58th government, the Justice and Development Party (AKP) captured 34.3% of the total votes, making Abdullah Gul Prime Minister, followed by the Republican People's Party (CHP) with 19.39% of the vote, led by Deniz Baykal. A special General Election was held again in the province of Siirt in March 2003, resulting in the election of AKP's chairman Recep Tayyip Erdogan to a seat in Parliament, allowing him to become prime minister. AKP and CHP were the only parties to surpass the 10% threshold required to hold seats in Parliament. The elections resulted in 363 of the 550 seats going to AKP, 178 seats to CHP, and 9 as independent. Due to a reshuffle in party affiliation and resignations, by 2007, AKP held 353 seats, CHP held 151 seats, Anavatan Party held 20 seats, independents held 10 seats, and five joined the True Path Party (DYP). In March 2004 nationwide local elections, AKP won 57 of 81 provincial capital municipalities and, with 41.8% of the votes for provincial council seats, consolidated its hold on power.

The Turkish Grand National Assembly was to have elected in May 2007 a new president to succeed President Sezer, whose term ended on May 16. Opposition parties led a Constitutional Court challenge to the electoral procedures, which resulted in a series of proposed constitutional amendments and early general elections on July 22. AKP won 46.6% of the vote, followed by CHP (20.9%), MHP (14.3%) and independents (5.2%). The new Parliament, which was sworn in on August 4, 2007 included 341 AKP members, 97 CHP members, 71 Nationalist Movement Party (MHP) members, 20 Democratic Society Party (DTP) members, 13 Democratic Left Party (DSP) members, one Freedom and Democracy Party (ODP) member, one Grand Unity Party (BBP) member, and five independents. Following the election, Sezer reappointed Erdogan as Prime Minister and then-Foreign Minister Gul again declared his presidential candidacy. The Parliament elected Gul in the third round of voting on August 28, 2007. Following Gul's move to the presidency, AKP seats in Parliament total 340; an MHP deputy died in August 2007, bringing the number of MHP members to 70; and the ban on a DTP deputy expired in July 2008, raising the number of DTP members to 21. President Gul approved Erdogan's proposed cabinet on August 29, 2007, and the new government received a vote of confidence on September 5. Nationwide local elections for municipal assembly and mayoral positions are scheduled for March 29, 2009.

In March 2008 the Constitutional Court agreed to hear a case to close down the AKP because of alleged "anti-secular" activities that contravene the Turkish Constitution. Seventy-one AKP members, including President Gul and Prime Minister Erdogan, were named in the case and could have been barred from politics for five years. On July 30, 2008 the court voted six in favor and five against closing down AKP; seven votes were required to close down the party. The court decided to cut the party's state funding, worth about $58 million, in half. None of the AKP members were banned.

Turkey entered NATO in 1952 and serves as the organization's vital eastern anchor, controlling the straits leading from the Black Sea to the Mediterranean and sharing a border with Syria, Iraq, and Iran. A NATO headquarters is located in Izmir. Besides its relationships with NATO and the EU, Turkey is a member of the OECD, the Council of Europe, and OSCE. Turkey also is a member of the UN and the Islamic Conference Organization (OIC). In December 1999, Turkey became a candidate for EU membership. On December 17, 2004, the EU decided to begin formal accession negotiations with Turkey in October 2005.

Turkey and the EU formed a customs union beginning January 1, 1996. The agreement covers industrial and processed agricultural goods. Turkey is harmonizing its laws and regulations with EU standards. Turkey adopted the EU's Common External Tariff regime, effectively lowering Turkey's tariffs for third countries, including the United States.

On October 3, 2005, Turkey and the EU reached agreement for Turkey to begin negotiations on accession to the European Union. Turkey and EU officials have begun the process of screening Turkey's laws and policies in order to begin negotiating the individual chapters required for ultimate EU accession.

Turkey opened and provisionally closed in 2006 one EU negotiating chapter on science and technology. Another chapter on statistics was opened in February 2007, and two more were opened in June 2007. Eight chapters, mostly related to trade, were suspended by the European Council in December 2006 after Turkey declined to open its ports and airports to Cypriot vessels--a commitment Turkey made as part of the Ankara Protocol and its EU Customs Union membership. Two new chapters were opened in each of the successive EU presidencies--December 2007 under the Portuguese, June 2008 under the Slovenians, and December 2008 under the French--bringing the total to ten open chapters.

Turkey is a member of the World Trade Organization (WTO). It has signed free trade agreements with the European Free Trade Association (EFTA), Israel, and many other countries. In 1992 Turkey and 10 other regional nations formed the Black Sea Economic Cooperation (BSEC) Council to expand regional trade and economic cooperation. Turkey chaired BSEC in 2007 and hosted in Istanbul the 15th BSEC Summit in June 2007.

In October 2008 Turkey was elected to hold a non-permanent seat on the United Nations Security Council for 2009-2010. Turkey took that seat January 1, 2009 and will hold the rotating presidency in June 2009.
