Introduction
The presidential system under the Turkish Constitution represents one of the most significant constitutional transformations in the modern legal history of Türkiye. The constitutional amendments adopted in 2017 changed the structure of government by replacing the former parliamentary model with a presidential model in which executive power is vested in the President of the Republic. This transformation affected the relationship between the legislature and executive, the legal status of ministers, the role of presidential decrees, parliamentary oversight mechanisms, administrative organization and constitutional review.
Under Article 104 of the Constitution, as amended by Act No. 6771, the President of the Republic is the head of the State and executive power is vested in the President. The same provision states that the President represents the Republic and the unity of the Turkish Nation and is responsible for ensuring the implementation of the Constitution and the orderly and harmonious functioning of state organs.
The Turkish presidential system should not be understood merely as a political model. It is a constitutional and legal framework that directly affects public administration, legislative-executive relations, judicial review, fundamental rights and legal certainty. For lawyers, companies, foreign investors, public institutions and individuals, understanding the presidential system is essential because many regulatory and administrative acts now derive from presidential authority or are shaped by presidential decrees.
1. Historical Background of the Turkish Presidential System
Before the 2017 constitutional amendments, Türkiye had a parliamentary system. Executive power was exercised through a dual structure consisting of the President and the Council of Ministers. The government was politically responsible to Parliament, and the Prime Minister played a central role in executive decision-making.
The 2017 amendments fundamentally changed this structure. The office of Prime Minister was abolished, the Council of Ministers was removed from the constitutional system, and executive authority was concentrated in the Presidency. Articles concerning the formation of the Council of Ministers, vote of confidence, political responsibility of ministers and regulations of the Council of Ministers were repealed as part of the constitutional change.
This shift created a new model of executive authority. Ministers are no longer members of a parliamentary government responsible through a classical vote of confidence mechanism. Instead, they are appointed and dismissed by the President. The President directly determines executive policy, appoints high-level public officials, issues presidential decrees in constitutionally permitted areas and directs public administration.
The purpose of the new model is often described as creating a more direct, stable and efficient executive structure. However, from a constitutional law perspective, the central legal issue is not only executive efficiency. The essential question is how executive power is limited, reviewed and balanced within the constitutional order.
2. Election and Democratic Legitimacy of the President
The presidential system is based on the direct election of the President. The Constitution provides that the President is elected by universal suffrage. In presidential elections, the candidate who receives the absolute majority of valid votes is elected President. If no candidate receives an absolute majority in the first ballot, a second ballot is held between the two candidates who received the greatest number of votes.
Direct election gives the President a strong democratic mandate. Unlike a parliamentary system, where the government emerges from the parliamentary majority, the Turkish presidential system creates a separate electoral legitimacy for the executive. Parliament and the President are both elected by the people, but they exercise different constitutional functions.
This separate legitimacy is one of the defining features of presidential systems. It may strengthen the executive’s political authority, but it also requires carefully designed checks and balances. If both the legislature and the President claim democratic legitimacy, constitutional rules must determine how conflicts are resolved. In Türkiye, these rules include the supremacy of law over presidential decrees, constitutional review by the Constitutional Court, parliamentary oversight mechanisms and the possibility of renewing elections.
3. Executive Power Vested in the President
The most important feature of the presidential system is that executive power is vested in the President. Article 104 makes this clear. The President is not merely a symbolic head of state. The President is the central executive authority.
The President’s constitutional duties include representing the Republic, ensuring the implementation of the Constitution, appointing and dismissing vice presidents and ministers, appointing high-level public officials, promulgating laws, sending laws back to Parliament for reconsideration, determining national security policy, representing the Office of Commander-in-Chief on behalf of the Grand National Assembly and deciding on the use of the Turkish Armed Forces in accordance with constitutional rules.
This concentration of executive power distinguishes the current system from the previous parliamentary model. In the former system, the Council of Ministers and Prime Minister had central executive functions. In the current system, ministers act within the presidential executive structure. Their appointment, dismissal and administrative role are connected to the President’s authority.
From a legal standpoint, this means that presidential acts, presidential decrees, appointments and administrative organization have become key subjects of constitutional and administrative law. Lawyers dealing with public law, regulatory law, public procurement, administrative sanctions, public employment or constitutional litigation must understand the legal scope of presidential authority.
4. The Abolition of the Prime Ministry and Council of Ministers
One of the clearest institutional consequences of the 2017 reform was the abolition of the Prime Ministry and the Council of Ministers as constitutional executive organs. The relevant constitutional provisions on the formation of the Council of Ministers, taking office, vote of confidence, vote of confidence while in office, functions and political responsibilities, formation of ministries and regulations were repealed.
This change removed the classical parliamentary responsibility mechanism. In a parliamentary system, the government depends on the confidence of Parliament. In the Turkish presidential system, the President does not require a parliamentary vote of confidence to exercise executive power. Ministers are not politically responsible to Parliament in the same manner as cabinet members under the former parliamentary system.
However, this does not mean that the executive is constitutionally unlimited. The President is bound by the Constitution and laws. Presidential decrees are limited by Article 104. Administrative acts remain subject to judicial review. Parliament continues to enact laws and exercise oversight mechanisms. The Constitutional Court reviews the constitutionality of laws and presidential decrees.
Therefore, the abolition of the parliamentary government model must be evaluated together with the constitutional mechanisms that limit and review executive authority.
5. Presidential Decrees as a New Regulatory Instrument
Presidential decrees are one of the most important legal instruments of the Turkish presidential system. Article 104 allows the President to issue presidential decrees on matters concerning executive power. This authority gives the President the ability to regulate certain executive matters without the need for prior parliamentary legislation.
However, presidential decree authority is not unlimited. The Constitution expressly provides several limitations. Fundamental rights, individual rights and duties, and political rights and duties cannot be regulated by presidential decree. Presidential decrees also cannot be issued on matters that the Constitution requires to be regulated exclusively by law, or on matters explicitly regulated by law. If there is a discrepancy between a presidential decree and a law, the law prevails. If Parliament enacts a law on the same matter, the presidential decree becomes null and void.
These limitations are central to the constitutional balance of the system. Presidential decrees are executive regulatory acts, not ordinary legislation. They cannot replace Parliament in areas reserved for law. They cannot override statutory provisions. They cannot be used to restrict fundamental rights in constitutionally protected fields.
For legal practice, the distinction between law and presidential decree is highly important. A dispute may arise over whether a presidential decree regulates a matter within executive power or whether it enters a field reserved for law. Such disputes may be brought before the Constitutional Court through constitutional review.
6. Constitutional Court Review of Presidential Decrees
The Constitutional Court plays a crucial role in controlling the presidential system. Article 148 provides that the Constitutional Court examines the constitutionality, in form and substance, of laws, presidential decrees and the Rules of Procedure of the Grand National Assembly, and also decides individual applications. Presidential decrees issued during a state of emergency or in time of war are excluded from constitutional review as to form or substance under the relevant constitutional rule.
The Court’s review of presidential decrees is essential because it defines the legal boundaries of executive regulatory power. The Constitutional Court has explained that the President’s authority to issue decrees is constitutionally delimited and that presidential decrees cannot be issued on matters explicitly regulated by law or reserved exclusively for law.
This review has practical significance. If a presidential decree regulates a subject already clearly governed by statute, it may be annulled. If it affects fundamental rights in a manner prohibited by Article 104, it may be unconstitutional. If it concerns the organization of ministries or executive administrative structure, it may fall within the permitted area, depending on the constitutional text and existing statutory framework.
Thus, the Constitutional Court is not merely an external observer of the presidential system. It is a constitutional boundary-setting institution that determines whether executive regulation remains within the permissible field.
7. Laws Prevail Over Presidential Decrees
A defining feature of the Turkish presidential system is the constitutional superiority of laws over presidential decrees. This rule prevents presidential decrees from becoming equivalent to parliamentary legislation.
If a law and a presidential decree regulate the same matter inconsistently, the law prevails. If Parliament later enacts a law on the same matter, the presidential decree becomes null and void.
This means that Parliament retains ultimate legislative authority. Presidential decrees may fill certain executive regulatory spaces, but Parliament can override them by enacting a law. In this sense, the presidential decree mechanism does not eliminate the legislative function of the Grand National Assembly. Instead, it creates a dual regulatory structure in which the constitutional hierarchy must be carefully observed.
For lawyers, this hierarchy is a powerful argument. If an administrative act is based on a presidential decree that conflicts with a statute, the statutory rule should prevail. If a decree regulates a matter already explicitly governed by law, its constitutionality may be questioned. If a decree affects fundamental rights beyond constitutional limits, individual and institutional remedies may be available.
8. Parliament Under the Presidential System
The Grand National Assembly of Türkiye continues to hold legislative power under the presidential system. It enacts, amends and repeals laws, adopts the budget, approves certain international treaties, exercises oversight mechanisms and performs constitutional functions assigned to it.
The presidential system changed the relationship between Parliament and the executive, but it did not remove Parliament from the constitutional structure. Parliament’s lawmaking power remains central, especially because laws prevail over presidential decrees.
Parliament also retains mechanisms for obtaining information and supervision. Article 98 provides that the Grand National Assembly exercises its powers of obtaining information and supervision through parliamentary inquiry, general debate, parliamentary investigation and written questions. Written questions are directed to vice presidents and ministers and must be answered in writing within the constitutional framework.
These mechanisms are important for transparency and accountability. Although the system no longer contains the classical vote of confidence mechanism, parliamentary oversight still functions as part of constitutional checks and balances.
9. Renewal of Parliamentary and Presidential Elections
Article 116 regulates the renewal of elections. The Grand National Assembly may decide to renew elections by a three-fifths majority of the total number of its members. In that case, parliamentary and presidential elections are held together. The President may also decide to renew elections, and again both elections are held together.
This mechanism reflects the interconnected nature of the Turkish presidential system. The renewal of one election results in the renewal of both. This rule may be seen as a constitutional mechanism designed to resolve political deadlock or renew democratic legitimacy.
The provision also has implications for presidential term limits. If Parliament decides to renew elections during the President’s second term, the President may once again be a candidate.
From a constitutional perspective, Article 116 is significant because it creates a high-threshold political reset mechanism. It is not an ordinary parliamentary vote of no confidence. It does not remove the President alone. Instead, it sends both the legislature and executive back to the electorate.
10. Vice Presidents and Ministers
In the presidential system, vice presidents and ministers are appointed by the President. They are not selected through a parliamentary confidence process. Their constitutional position reflects the executive-centered structure of the system.
Vice presidents may act on behalf of the President in certain circumstances. Ministers manage their respective ministries within the presidential executive framework. The establishment, abolition, duties, powers, organizational structure and central and provincial organizations of ministries may be regulated by presidential decree under the constitutional framework.
This structure creates administrative unity under the Presidency. It also makes presidential decrees particularly important in determining ministerial organization, administrative hierarchy and public service delivery.
However, vice presidents and ministers are still subject to constitutional accountability mechanisms. Parliament may conduct parliamentary investigations concerning vice presidents and ministers under the procedures provided by the Constitution. Written questions may also be addressed to vice presidents and ministers.
11. State Supervisory Council and Administrative Control
The presidential system strengthened certain presidential administrative control mechanisms. Article 108 regulates the State Supervisory Council, which is attached to the Presidency. Its purpose is to ensure the lawfulness, regular and efficient functioning and improvement of administration. The Council may conduct administrative investigations, inquiries and inspections over many public bodies and organizations upon the request of the President. Judicial organs are expressly outside the jurisdiction of the State Supervisory Council.
This institution reflects the President’s role in ensuring administrative coordination and legality within the executive branch. However, its exclusion of judicial organs is important for separation of powers and judicial independence.
The State Supervisory Council should not be confused with judicial review. It is an administrative oversight body attached to the Presidency. Courts remain responsible for judicial review of administrative acts and for protecting individuals against unlawful administrative measures.
12. National Security and Commander-in-Chief Functions
The presidential system also affects national security and military-related constitutional functions. The President represents the Office of Commander-in-Chief of the Turkish Armed Forces on behalf of the Grand National Assembly and is responsible to Parliament for national security and preparation of the armed forces for defense.
The National Security Council is chaired by the President and includes vice presidents, certain ministers, the Chief of the General Staff and force commanders. The Council submits advisory decisions and views concerning national security policy to the President, who evaluates them within the constitutional framework.
These provisions illustrate the central role of the Presidency in national security policy. However, the constitutional text also preserves references to the Grand National Assembly, particularly in relation to Commander-in-Chief authority and national security responsibility.
13. State of Emergency Under the Presidential System
Article 119 gives the President authority to declare a state of emergency in specific circumstances, such as war, mobilization, widespread violence threatening constitutional order or fundamental rights, serious deterioration of public order, natural disasters, dangerous epidemics or serious economic crisis. A state of emergency may be declared for a period not exceeding six months. The decision must be published in the Official Gazette and submitted to Parliament for approval on the same day. Parliament may reduce, extend or lift the state of emergency.
During a state of emergency, the President may issue presidential decrees on matters required by the emergency, notwithstanding certain limitations applicable in ordinary periods. These decrees have the force of law, must be published in the Official Gazette and submitted to Parliament for approval. Except where Parliament cannot convene due to war or force majeure, emergency presidential decrees must be debated and decided by Parliament within three months; otherwise, they are automatically annulled.
This emergency regime demonstrates both the strength and the limits of presidential authority. The President can act quickly in extraordinary conditions, but parliamentary approval remains a constitutional requirement.
14. Judicial Independence in the Presidential System
A presidential system requires a strong and independent judiciary. The concentration of executive power in the Presidency increases the importance of judicial review, constitutional adjudication and access to effective remedies.
Judicial power in Türkiye is exercised by independent and impartial courts. Courts review administrative acts, resolve disputes and protect fundamental rights. The Constitutional Court reviews laws and presidential decrees and decides individual applications. The Council of Judges and Prosecutors exercises its functions according to the principles of independence of courts and security of tenure of judges.
Judicial independence is not merely an institutional value. It is a practical guarantee for individuals and businesses. Without independent courts, presidential decrees, administrative acts and executive decisions could not be effectively reviewed. Therefore, the judiciary is a key safeguard in the presidential system.
15. Individual Application and Rights Protection
Individual application to the Constitutional Court is an important rights-protection mechanism under the presidential system. Individuals may apply to the Constitutional Court when they claim that public authorities have violated fundamental rights and freedoms protected by the Constitution and falling within the scope of the European Convention on Human Rights, provided that ordinary remedies have been exhausted.
This mechanism ensures that the presidential system remains connected to constitutional rights protection. Executive acts, administrative measures, judicial proceedings and other uses of public power may be challenged from a rights-based perspective after ordinary remedies are exhausted.
Individual application is not a normal appeal. The Constitutional Court does not review every legal or factual error. It examines whether a constitutional right has been violated. In the presidential system, this remedy is especially important because it provides direct constitutional protection against rights violations caused by public authority.
16. Checks and Balances in the Turkish Presidential System
The Turkish presidential system contains several checks and balances. First, laws prevail over presidential decrees. Second, Parliament may enact laws on matters regulated by decree, causing the decree to become null and void. Third, the Constitutional Court reviews presidential decrees in ordinary periods. Fourth, administrative acts remain subject to judicial review. Fifth, Parliament exercises oversight through inquiry, general debate, parliamentary investigation and written questions. Sixth, elections may be renewed under Article 116. Seventh, individual application provides rights-based constitutional control.
The effectiveness of these mechanisms depends on legal culture, institutional practice and compliance with constitutional judgments. A presidential system is constitutionally sound only when executive authority is balanced by strong legal limits, transparent accountability and independent judicial review.
Therefore, the key issue is not whether the President has broad authority. The key issue is whether that authority is exercised within the Constitution and whether legal remedies operate effectively when boundaries are crossed.
17. Practical Importance for Lawyers, Companies and Individuals
The presidential system has practical consequences for legal practice in Türkiye. Many administrative and regulatory matters are now connected to presidential decrees, presidential decisions, ministerial organization under presidential authority and executive policy determined by the Presidency.
For lawyers, this means that public law disputes often require analysis of constitutional hierarchy. Is the legal basis a law, presidential decree, regulation or administrative act? Does a presidential decree conflict with a statute? Is the matter reserved exclusively for law? Does the measure affect fundamental rights? Is judicial review available? These questions may determine litigation strategy.
For companies and investors, the presidential system affects regulatory predictability, public procurement, licensing, taxation, administrative sanctions, investment incentives, sectoral regulation and public administration. Legal certainty requires careful monitoring of presidential decrees and related administrative regulations.
For individuals, the system affects rights protection in areas such as public employment, social security, disciplinary law, freedom of expression, property rights, access to court and administrative remedies. Constitutional arguments may be necessary where executive action imposes disproportionate burdens.
18. Advantages and Legal Debates
Supporters of the presidential system argue that it creates executive stability, direct democratic legitimacy, faster decision-making and clearer responsibility. By eliminating coalition-based government formation problems and parliamentary confidence crises, the system may produce a more stable executive.
However, constitutional debates focus on the concentration of executive power, the scope of presidential decrees, parliamentary oversight, judicial independence and the practical effectiveness of checks and balances. These debates are not merely political. They have direct legal consequences for rule of law, fundamental rights, legal certainty and administrative accountability.
The most important legal debate concerns the boundary between law and presidential decree. Article 104 sets textual limits, but actual disputes require interpretation. The Constitutional Court’s case-law is therefore crucial in defining the permissible scope of presidential decree authority.
Conclusion
The presidential system under the Turkish Constitution is a comprehensive constitutional model that reshaped the organization of executive power in Türkiye. With the 2017 amendments, executive power was vested in the President, the Prime Ministry and Council of Ministers were abolished, presidential decrees became a major regulatory instrument, and legislative-executive relations were restructured.
The President has broad constitutional powers, including executive leadership, appointments, promulgation of laws, issuance of presidential decrees, national security responsibilities and state of emergency authority. However, these powers are not unlimited. Presidential decrees cannot regulate protected rights fields, cannot regulate matters reserved exclusively for law and cannot override statutes. Laws prevail over presidential decrees, and Parliament may enact laws that render decrees null and void.
The Constitutional Court plays a decisive role in maintaining the constitutional boundaries of the presidential system. Through review of presidential decrees and individual applications, it protects constitutional supremacy and fundamental rights. Parliament continues to hold legislative power and oversight functions. Administrative acts remain subject to judicial review.
For lawyers, companies, investors and individuals, the presidential system is not only a matter of political organization. It is a practical legal framework that affects regulation, litigation, public administration and rights protection. Understanding the system requires careful analysis of constitutional hierarchy, presidential decree authority, parliamentary lawmaking, judicial review and fundamental rights.
In conclusion, the Turkish presidential system is best understood as a model of strong executive authority operating within constitutional limits. Its legitimacy and effectiveness depend on the proper functioning of checks and balances, the supremacy of law, judicial independence and respect for fundamental rights.
