# 2010 Turkish constitutional referendum

A constitutional referendum on a number of changes to the constitution was held in Turkey on 12 September 2010. The results showed the majority supported the constitutional amendments, with 58% in favour and 42% against. The changes were aimed at bringing the constitution into compliance with European Union standards. Supporters of Turkish EU membership hope constitutional reform will facilitate the membership process.

## Background

After the military coup of 12 September 1980, a new constitution was drafted, designed by the military junta that came to power. Thirty years later, a referendum was held regarding a number of amendments to that constitution.
In 2010, the Turkish parliament adopted a series of constitutional amendments. The amendments did not achieve the required two-thirds majority (67%) for immediately implementing the changes. However, a majority of 330 votes (60%) was achieved and sufficient to present the amendments to the electorate in a referendum. A constitutional change, to make it more difficult for the Supreme Court to dissolve parties, failed to pass.
The reform package was accepted by parliament on 7 May, initiating the referendum process. The referendum was expected to be held 60 days after the publication of the package in the Official Gazette, but the Supreme Election Board (YSK) announced that it would be held 120 days later, on 12 September.

## Changes by theme
### Coup leaders and military personnel

Provisional Article 15 of the Constitution, which provided protection to coup leaders, will be abolished. The amendments will allow the leaders of the 1980 coup to be sent to court. Military officers who commit crimes against the state, such as preparing coup plans, will be tried in civilian courts. Military personnel who are dismissed from the Turkish Armed Forces will have the right to appeal to the judiciary, the right to legal remedies and the right of defense.
Personal information such as names, photographs and ID information will be kept private. This kind of information will be stored only if the individual agrees to it, and individuals believing their personal information is being misused will be able to hold relevant entities accountable.

### Economic and social rights

Businesspeople with tax debts will be able to travel abroad. Businesspeople facing an investigation or prosecution are prohibited from traveling abroad under current regulations. In the amendments, businesspeople will be able to travel abroad provided there is no court order restricting their travel.
Right to collective bargaining for government employees. While government employees will be granted the right to collective bargaining, the Public Employees' Arbitration Board consisting of government employee representatives will have the final say. The same right will be granted to the retired. Government employees who believe they have been punished unfairly will be able to go to court.
Restrictions on the right to strike will be removed. Restrictions on politically motivated strikes and lockouts will be removed to advance workers' rights. Labor unions will not be held liable for material damage to a workplace where a strike is being held as a result of deliberately negligent behavior by the workers and by the labor union.
The Economic and Social Council (ESK), which comprises representatives from unions, associations and confederations, will be given constitutional protection. The council will be effective in determining economic policies and the government's involvement in council activities will be removed.

### Individual freedoms

Problems between the state and citizens will be resolved by way of an ombudsman without having to go to court. If citizens are not satisfied with judicial decisions, they will be able to directly petition the Constitutional Court.
Measures enacted to ensure equal rights for men and women will not be interpreted as contrary to the principle of equality, nor those enacted to protect children, elderly people, disabled people, widows and orphans of martyrs as well as for invalid and veterans.
Since the structure of the Constitutional Court will change, closing down parties will not be as easy as it used to be. Deputies will not be banned from politics if their party is closed down, but will keep their seats for the normal term.
Government workers, who until now could only be a member of one labor union, will now have a choice. Additionally, warnings and reprimands given to government employees will be open to judicial review. Government employees who believe they have been punished unfairly will be able to make claims in court.

### Judicial reforms

Parliament will choose some of the members of the Constitutional Court. The number of Constitutional Court members will be expanded. Parliament will appoint three members while the president will appoint 14 members. The Constitutional Court will obtain a more democratic structure, consisting of two parts and functioning as a general assembly.
The Supreme Board of Judges and Prosecutors (HSYK) will increase in number from 7 to 22. Members will no longer be elected only by the Supreme Court of Appeals and the Council of State. A total of 11 judges from around 13,000 judges will be appointed to the board to represent judges on the bench.
Dismissed judges will be able to appeal to the judiciary. The HSYK's decisions, like YAŞ decisions, will be open to judicial review. Prosecutors and judges dismissed by the board will be able to challenge dismissal decisions in court.
All citizens will be able to file a petition with the Constitutional Court. This is now only possible at the European Court of Human Rights.
Besides the President, the ministers and other senior government officials, the chairman of the parliament and the supreme commander of the Turkish army can now also appear in the Supreme Court (Yüce Divan).

## Voting in parliament

On 30 March 2010, Turkey's ruling party submitted its package of constitutional amendments to the parliament. The changes were passed in parliament in late April and early May 2010 with over 330 votes, below the two-thirds majority of 367 votes needed to pass them directly, but enough to send them to a referendum within sixty days after President Abdullah Gül signs the law. On 13 May 2010, president Gül signed the reform package.
The composition of the parliament (550 seats) during the voting was as follows: AKP: 336, CHP: 97, MHP: 69, BDP: 20, Independent: 12, DSP: 6, DP: 1, TP: 1. The ruling Justice and Development Party (AKP) has 336 seats, but deputy Mehmet Ali Şahin cannot vote as he is the parliament speaker. CHP and BDP decided to boycott the voting. The Nationalist Movement Party (MHP) voted against the articles.
Each article required more than 330 votes in order to pass. The amendment for Article 69, which would have limited the ability of the Supreme Court to dissolve political parties, did not meet this threshold in the second round and was therefore dropped from the package.

## Annulment of the package

The main opposition party CHP not only argues that the constitutional package includes unconstitutional reforms, but also that it was passed through procedural violations. It wants the Constitutional Court to review the proposal process. The CHP's legal advisers also argued that the changes the package makes to the structures of the Constitutional Court and the Supreme Board of Judges and Prosecutors (HSYK) are in violation of the constitutional principle of separation of powers. With this claim, the CHP alleges that the AKP is attempting to change one of Turkey's constitutional articles that cannot be amended. So in addition to a review of the package on procedural grounds, the CHP also demands a review of the content of the package. The CHP also demands a stay of the referendum results, bringing the total of CHP demands to three.
On 7 July 2010, the Turkish Constitutional Court delivered its final verdict on a package of constitutional amendments, which is to be subject to a public referendum on 12 September. The court has ruled in favour of the vast majority of the government's proposed reforms to the constitution. The court did not annul the whole package. Judges annulled certain parts of two articles, but rejected the demands of the Turkish opposition to scrap the whole package on technical grounds. The partially annulled articles pertain to the structure of the Constitutional Court and the Supreme Board of Judges and Prosecutors (HSYK). They were controversial due to the changes envisioned in the member appointment processes.
Both the government and the opposition expressed disappointment with the Court's decision.

### Voting irregularities

Kemal Kılıçdaroğlu, the leader of the opposition represented by the Republican People's Party (CHP), could not vote because of a mix-up over where he should cast his ballot. "It was my responsibility to check the register of electors, but I could not do it due to my intense referendum campaign," he said.

## Reactions
### Domestic

* Justice and Development Party (AKP) – Following the announcement of the results, Prime Minister Erdoğan said the state had "crossed a historic threshold toward advanced democracy and the supremacy of law."
* Republican People's Party (CHP) – Pointing to the 42% of voters who said "No" at the referendum, Kılıçdaroğlu said such a figure could not be underestimated and his party had a major role in reaching such a rate. "When we look at the result, we see that the Justice and Development Party has taken a very important step towards creating a judiciary mechanism that is entirely dependent on itself," Kılıçdaroğlu said. He also added Erdoğan administration was seeking dangerous levels of control over the country's judiciary, with two of the 26 approved amendments allegedly giving excessive influence to the government over the courts.
* Nationalist Movement Party (MHP) – Having been the first to publish a written statement, party leader Devlet Bahçeli claimed that with the constitutional amendments which will serve the backdoor intentions of the AKP to create a sectarian judiciary being approved by the Turkish nation, Turkey was dragged into the Dark Ages littered with dangers and vital threats, adding that bad days are ahead.
