Introduction
The Grand National Assembly of Türkiye is one of the central institutions of Turkish constitutional law. It represents the legislative branch, exercises law-making authority, adopts the national budget, approves international treaties, participates in constitutional amendment procedures, performs parliamentary oversight and carries out other duties assigned by the Constitution. In a constitutional democracy, Parliament is not merely a political forum; it is a constitutional organ through which national sovereignty, democratic representation and legislative authority are exercised.
The Constitution of the Republic of Türkiye establishes the Grand National Assembly as the organ exercising legislative power. Article 7 states that legislative power is vested in the Grand National Assembly of Türkiye on behalf of the Turkish Nation and that this power cannot be delegated. This rule places Parliament at the center of democratic law-making and constitutional legitimacy. The Assembly is not only a body that debates political issues; it is the institution through which laws are enacted, amended and repealed within the constitutional order.
The role of the Grand National Assembly became especially important after the constitutional amendments that transformed Türkiye from a parliamentary system into a presidential system. Under the current system, executive power is vested in the President, while legislative power remains with the Grand National Assembly. This makes the relationship between Parliament, the President, the Constitutional Court and the judiciary a key issue in Turkish constitutional law.
1. Constitutional Position of the Grand National Assembly
The Grand National Assembly is the constitutional organ of legislative power. Its legitimacy comes from democratic elections and national representation. In Turkish constitutional theory, Parliament embodies national sovereignty in the legislative field, but it does so within the limits of the Constitution.
Article 6 of the Constitution provides that sovereignty belongs to the Nation without restriction or condition, and that no person or organ may exercise state authority unless authorized by the Constitution. Article 7 then gives legislative power to the Grand National Assembly. Together, these provisions mean that Parliament exercises legislative authority on behalf of the Nation, but only within the constitutional framework.
This distinction is essential. The Grand National Assembly is democratically legitimate, but it is not legally unlimited. It cannot enact laws contrary to the Constitution. Article 11 provides that constitutional provisions are binding fundamental legal rules and that laws cannot be contrary to the Constitution. Therefore, parliamentary law-making is subject to constitutional supremacy.
2. Legislative Power and Non-Delegation
The most fundamental role of the Grand National Assembly is to exercise legislative power. Legislative power includes the authority to enact, amend and repeal laws. Article 87 expressly lists this among the duties and powers of the Assembly.
The non-delegation of legislative power is a key constitutional principle. Since Article 7 states that legislative power cannot be delegated, the Assembly cannot transfer its core law-making authority to another organ. This rule protects democratic legitimacy and prevents legislative authority from being absorbed by the executive.
However, non-delegation does not mean that the executive cannot issue regulations. The President may issue presidential decrees in matters relating to executive power, but such decrees are constitutionally limited. They cannot override laws, cannot regulate matters reserved exclusively for law and cannot regulate certain fields of fundamental rights. Therefore, the Grand National Assembly remains the primary law-making authority in the Turkish constitutional system.
3. Parliament and the Hierarchy of Norms
The Grand National Assembly operates within the hierarchy of norms. The Constitution is the supreme legal norm. Laws enacted by Parliament must comply with the Constitution. Presidential decrees, regulations and administrative acts must also comply with both the Constitution and, where applicable, statutes.
This hierarchy is especially important in the presidential system. Presidential decrees may regulate certain executive matters, but laws prevail over presidential decrees in case of conflict. If Parliament enacts a law on a matter regulated by presidential decree, the decree becomes legally ineffective on that matter. This confirms that Parliament retains a superior role in statutory regulation.
The Constitutional Court protects this hierarchy by reviewing the constitutionality of laws and presidential decrees. Article 148 gives the Constitutional Court authority to examine the constitutionality of laws, presidential decrees and the Rules of Procedure of the Grand National Assembly.
4. Introduction and Deliberation of Bills
The legislative process begins with the introduction of bills. Under Article 88, deputies are empowered to introduce bills, and the procedure for deliberating bills is regulated by the Rules of Procedure of the Grand National Assembly.
This rule reflects the role of deputies as elected representatives. Deputies do not merely vote on proposals; they may also initiate legislation. Through legislative proposals, deputies can bring social, economic, legal and political issues into parliamentary debate.
The deliberation of bills is also important for democratic transparency. Laws should not be produced as purely technical texts without public reasoning. Parliamentary debate allows different political groups, commissions and deputies to evaluate legal consequences, constitutional compatibility and public interest.
For lawyers and legal practitioners, the legislative history of a law may also be useful in interpretation. Parliamentary debates, commission reports and legislative reasoning can help explain the purpose of statutory provisions.
5. Promulgation of Laws and Presidential Reconsideration
After Parliament adopts a law, the President has a constitutional role in promulgation. Article 89 provides that the President promulgates laws adopted by the Grand National Assembly within fifteen days. The President may also return laws deemed unsuitable for promulgation to Parliament for reconsideration, except for budget laws. If Parliament adopts the returned law without amendment by an absolute majority, the President must promulgate it.
This mechanism creates a constitutional interaction between Parliament and the President. The President may request reconsideration, but cannot permanently veto a law if Parliament insists with the required majority.
This system preserves legislative authority while allowing an additional constitutional checkpoint. The President’s return power may encourage Parliament to reconsider legal, political or constitutional concerns. However, final legislative authority remains with the Grand National Assembly once it satisfies the constitutional majority requirements.
6. Budgetary Authority of the Grand National Assembly
One of the most important roles of Parliament is budgetary authority. The power to debate and adopt the budget is a central feature of democratic governance. Article 87 lists debating and adopting budget bills and final accounts bills among the duties and powers of the Grand National Assembly.
Budget authority is not merely financial. It is constitutional and political. Through the budget, Parliament determines how public resources are allocated, how public services are financed and how the executive may spend public funds.
The budget process also supports accountability. Public revenue and expenditure must be subject to parliamentary debate. Without parliamentary budget authority, the executive could exercise financial power without democratic control.
For constitutional law, the budget represents the practical link between legislation, public administration and democratic supervision. It affects social rights, public investment, national defense, education, healthcare, infrastructure, justice services and administrative capacity.
7. Final Accounts and Financial Accountability
The adoption of final accounts is another important parliamentary function. While the budget authorizes future expenditure, final accounts allow Parliament to review how public funds were actually used.
This function supports transparency and accountability. The executive may propose and implement financial policies, but the Assembly has a constitutional role in examining whether public funds were spent within legal limits.
Financial accountability is especially important in a social state governed by the rule of law. Public money belongs to the public. Therefore, expenditure must be lawful, transparent and subject to democratic control.
In constitutional terms, budget and final account powers show that Parliament is not only a law-making body but also a financial supervisory institution.
8. Parliamentary Oversight
Parliamentary oversight is one of the main mechanisms through which the Grand National Assembly controls and supervises the executive. Article 98 regulates the Assembly’s powers of obtaining information and supervision. These include parliamentary inquiry, general debate, parliamentary investigation and written questions.
The form of oversight changed after the transition to the presidential system. The classical parliamentary vote of confidence and interpellation mechanisms no longer operate in the same way as they did under the former parliamentary system. Nevertheless, Parliament retains oversight tools that allow it to request information, investigate public matters and question executive officials.
Written questions are directed to vice presidents and ministers. Parliamentary investigations may concern certain high-level executive officials under constitutional procedures. These mechanisms support transparency and accountability, even though the current system is not based on parliamentary confidence in the classical sense.
9. Parliamentary Investigation and Executive Accountability
Parliamentary investigation is one of the most serious oversight tools. It may lead to constitutional and legal consequences for high-level executive officials. Under the presidential system, accountability mechanisms are designed differently from parliamentary systems, but Parliament still has a role in investigating allegations concerning executive officials.
This function reflects the principle that public office is not immune from accountability. Ministers, vice presidents and other officials exercise public power. Where serious allegations arise, parliamentary mechanisms may be used within the constitutional framework.
The practical importance of parliamentary investigation lies in its institutional character. It is not ordinary criminal prosecution, but a constitutional mechanism combining parliamentary procedure and legal accountability.
10. Approval of International Treaties
The Grand National Assembly also has an important role in international law. Article 87 states that the Assembly has the power to approve the ratification of international treaties.
This function is constitutionally significant because international treaties may affect domestic law, foreign policy, human rights, trade, investment, defense and administrative obligations. By requiring parliamentary approval for many treaties, the Constitution ensures democratic participation in international commitments.
Article 90 further provides rules on the ratification and domestic effect of international treaties. International agreements duly put into effect have the force of law, and in case of conflict between domestic laws and international agreements concerning fundamental rights and freedoms, the international agreement prevails.
Thus, Parliament’s treaty approval function can have major domestic consequences, especially in human rights and investment law.
11. Amnesty and Pardon Powers
Article 87 also provides that the Grand National Assembly may decide to proclaim amnesty and pardon with a three-fifths majority.
Amnesty and pardon powers are exceptional because they affect criminal liability and execution of penalties. They may have major social, political and legal consequences. For this reason, the Constitution requires a qualified majority.
This function demonstrates that Parliament’s constitutional role extends beyond ordinary legislation. It may make exceptional decisions affecting criminal justice, social reconciliation and public policy.
However, amnesty powers must be exercised carefully. They should be consistent with the rule of law, equality, victims’ rights, public order and constitutional principles.
12. Declaration of War and Use of Armed Forces
The Grand National Assembly has significant powers in matters of war and national defense. Article 87 lists declaring war among the duties and powers of Parliament.
The Assembly’s role in war-related decisions reflects the democratic control of the most serious forms of state power. War affects national security, public finance, individual rights, foreign policy and the lives of citizens. It cannot be treated as an ordinary executive matter.
The Constitution also contains rules concerning authorization for the deployment of armed forces and related matters. Parliament’s involvement in these issues protects democratic legitimacy and ensures that military decisions of constitutional importance remain subject to representative approval.
This function shows that the Grand National Assembly is a key actor not only in domestic law-making but also in the constitutional control of national security decisions.
13. Constitutional Amendment Power
The Grand National Assembly has a central role in constitutional amendments. Article 175 provides that amendments to the Constitution must be proposed in writing by at least one-third of the total number of members of the Assembly. The proposal must be debated twice in the Plenary and adopted by secret ballot with at least a three-fifths majority of the total number of members.
This procedure is much stricter than ordinary law-making. It reflects the special status of the Constitution as the supreme legal norm. Parliament may amend the Constitution only by following the procedure and majority thresholds established by the Constitution itself.
However, Parliament’s amendment power is not unlimited. Article 4 protects Articles 1, 2 and 3 from amendment and even from proposal. These provisions concern the republican form of the State, the characteristics of the Republic, the indivisible integrity of the State, the official language, flag, national anthem and capital.
Therefore, the Assembly is both the constitutional amendment organ and an organ limited by the Constitution.
14. Parliamentary Elections and Representative Legitimacy
The authority of the Grand National Assembly depends on democratic elections. Deputies are elected to represent the Nation. Their legitimacy comes from public vote and constitutional election rules.
Representative legitimacy matters because laws affect the entire society. Criminal rules, tax obligations, civil rights, administrative powers, social security rules, public services and economic regulations are all shaped by legislation. For such rules to be legitimate, they must be enacted by a democratically elected legislative body.
At the same time, representation does not mean unlimited majority power. Constitutional democracy requires that parliamentary majorities respect fundamental rights, minority rights, judicial review and constitutional limits.
The Assembly therefore represents both democratic authority and constitutional responsibility.
15. Parliamentary Immunity and Legislative Independence
Parliamentary immunity and legislative irresponsibility protect the independence of deputies and the Assembly. These mechanisms allow deputies to perform their duties without fear of arbitrary prosecution or pressure.
The purpose of parliamentary immunity is not to create personal privilege. It protects parliamentary function, political debate and democratic representation. Deputies must be able to speak, vote and represent political views freely within constitutional limits.
However, parliamentary immunity is subject to constitutional procedures and limitations. The balance between legislative independence and accountability is important. Immunity should protect democratic representation, but it should not become a tool for impunity in matters unrelated to parliamentary function.
16. Parliament and Fundamental Rights
The Grand National Assembly plays a major role in protecting and restricting fundamental rights. Many constitutional rights may be regulated or limited by law. Article 13 provides that fundamental rights and freedoms may be restricted only by law, without infringing upon their essence and in conformity with proportionality and democratic order.
This means that Parliament has a dual role. It may enact laws regulating rights, but it must do so constitutionally. A statute restricting expression, property, assembly, privacy, liberty or access to court must satisfy legality, legitimate aim, protection of the essence of rights and proportionality.
Parliament also has a positive role. It may enact laws that protect vulnerable groups, strengthen judicial remedies, regulate social rights, protect personal data, prevent discrimination and improve access to justice.
Thus, fundamental rights are shaped not only by courts but also by legislative policy.
17. Parliament and the Constitutional Court
The relationship between the Grand National Assembly and the Constitutional Court is central to Turkish constitutional law. Parliament enacts laws, while the Constitutional Court reviews whether those laws comply with the Constitution.
This does not mean that the Constitutional Court is a second legislative chamber. Its function is not to make policy but to enforce constitutional limits. Article 148 gives the Court authority to review laws and presidential decrees. Article 153 provides that Constitutional Court judgments are final and binding on legislative, executive and judicial organs, administrative authorities and real and legal persons.
This relationship reflects constitutional supremacy. Parliament has democratic law-making authority, but its laws must conform to the Constitution. If a law violates the Constitution, the Constitutional Court may annul it.
For lawyers, this relationship is important because unconstitutional laws may be challenged through abstract review by authorized actors or concrete review during ordinary litigation.
18. Parliament and Presidential Decrees
In the presidential system, the relationship between laws and presidential decrees is one of the most important issues. Presidential decrees may regulate certain executive matters, but laws enacted by Parliament prevail over conflicting presidential decrees.
This confirms the continuing importance of Parliament. The executive may act through decrees in its constitutional field, but Parliament can regulate matters by law. Where a law exists, it has priority over a presidential decree in cases of conflict.
This structure is a key element of checks and balances. It prevents executive regulation from replacing parliamentary legislation. It also gives Parliament the ability to define legal frameworks in important policy areas.
For constitutional practice, disputes may arise over whether a presidential decree regulates a matter reserved for law or conflicts with existing legislation. Such disputes may reach the Constitutional Court.
19. Parliament and State of Emergency
The Grand National Assembly also has an important role in emergency governance. Article 119 provides that a state of emergency declared by the President must be published in the Official Gazette and submitted to the Assembly for approval on the same day. Parliament may reduce, extend or lift the state of emergency.
This parliamentary role is essential because emergency powers may affect fundamental rights, public administration and the balance of powers. Executive speed may be necessary in emergencies, but democratic control remains constitutionally important.
Emergency presidential decrees must also be submitted to Parliament. Except where Parliament cannot convene due to war or force majeure, such decrees must be debated and decided within the constitutional period; otherwise, they are automatically annulled.
Thus, Parliament is a constitutional safeguard against indefinite or unchecked emergency governance.
20. Practical Importance of the Grand National Assembly for Lawyers and Citizens
The Grand National Assembly affects almost every area of legal practice. Laws enacted by Parliament regulate civil law, criminal law, commercial law, labor law, tax law, administrative law, enforcement law, family law and constitutional remedies.
For lawyers, understanding Parliament’s constitutional role helps in interpreting statutes, challenging unconstitutional laws, analyzing legislative purpose and evaluating the validity of public measures. A dispute may appear to concern ordinary legislation, but the constitutional source, legislative competence and compatibility with fundamental rights may become decisive.
For citizens, Parliament is the institution through which democratic preferences are transformed into law. For companies and investors, parliamentary legislation determines regulatory certainty, property rights, tax obligations, investment incentives and judicial remedies.
Therefore, the role of the Grand National Assembly is not limited to politics. It is directly connected to legal certainty, constitutional rights and the practical operation of the Turkish legal system.
Conclusion
The Grand National Assembly of Türkiye is one of the core institutions of Turkish constitutional law. It exercises legislative power on behalf of the Turkish Nation, enacts, amends and repeals laws, debates and adopts the budget and final accounts, approves international treaties, declares war, decides on amnesty and pardon, performs parliamentary oversight and participates in constitutional amendment procedures.
Its constitutional role reflects democratic representation and national sovereignty. However, parliamentary authority is not unlimited. The Assembly is bound by the Constitution. Laws cannot be contrary to the Constitution, and the Constitutional Court may review parliamentary legislation for constitutionality. This balance between democratic law-making and constitutional supremacy is central to Turkish constitutional democracy.
After the transition to the presidential system, the Grand National Assembly’s role remains essential. Executive power is vested in the President, but legislative power remains with Parliament. Laws prevail over presidential decrees, Parliament approves budgets, exercises oversight, participates in emergency governance and retains constitutional amendment authority within strict procedural and substantive limits.
For lawyers, citizens, companies and foreign investors, the Grand National Assembly is not merely a political institution. It is the source of statutory law and a key actor in the protection, limitation and organization of constitutional rights. Understanding its role is essential for understanding the Turkish legal system as a whole.
