Recognition and enforcement of foreign arbitral awards in Türkiye under the 1958 New York Convention: MTK Article 62, Article V grounds for refusal, public policy and Court of Cassation case law.
The Convention on the Recognition and Enforcement of Foreign Arbitral Awards, signed in New York on 10 June 1958 (the "New York Convention" or "1958 NYC"), is regarded as the most successful and broadly applied multilateral instrument in international arbitration law. With more than 170 contracting states today, the Convention constitutes the fundamental legal basis for the cross-border effectiveness of foreign arbitral awards. Türkiye acceded to the Convention by ratification law dated 21 May 1991 and the Convention entered into force on 25 September 1992. This article examines the structure of the New York Convention, its application framework in Türkiye, its interaction with the Turkish Code on Private International and Procedural Law No. 5718 (MÖHUK), and the principal trends in Court of Cassation jurisprudence.
1. The Structure of the New York Convention and Türkiye's Party Status
The New York Convention consists of sixteen articles and contains both substantive provisions governing the recognition and enforcement of foreign arbitral awards and procedural provisions safeguarding the validity of arbitration agreements between states. The fundamental purpose of the Convention is to enable arbitral awards to be recognised and enforced in other contracting states independently of the seat of arbitration. When acceding to the Convention, Türkiye made two reservations: the reciprocity reservation (awards rendered only in contracting states shall be enforced) and the commercial dispute reservation (the Convention shall apply to disputes arising out of relationships considered commercial under Turkish law). These reservations are the fundamental parameters shaping the Convention's scope of application in Türkiye.
2. Relationship Between the Convention and MÖHUK; Applicable Law
In Türkiye, there are two fundamental legal sources regarding the enforcement of foreign arbitral awards: the New York Convention and Articles 60-63 of MÖHUK. According to the established case law of the Court of Cassation, the New York Convention applies primarily to awards rendered in contracting states; MÖHUK provisions are resorted to in matters not covered by, or requiring clarification of, the Convention. The enforcement procedure is conducted before the commercial court of first instance as the competent court, is subject to simplified proceedings, and parties must be summoned to a hearing. From the perspective of enforcement law, the enforcement decision has the character of a judgment and is implemented under the provisions of the Code on Enforcement and Bankruptcy.
3. Grounds for Refusal Under Article V: The Principle of Exhaustive Enumeration
Article V of the New York Convention sets out, on an exhaustive (numerus clausus) basis, the grounds upon which the court of enforcement may refuse the enforcement of a foreign arbitral award. Paragraph 1 of Article V regulates six grounds for refusal that must be invoked by the parties: invalidity of the arbitration agreement on grounds of incapacity, failure to give proper notice to the parties or violation of the right of defence, the award addressing matters falling outside the scope of the arbitration agreement, non-compliance of the composition of the arbitral tribunal or arbitration procedure with the parties' agreement or the law of the seat, and the award not having become binding on the parties, having been set aside, or its enforcement having been suspended in the country of the seat. Paragraph 2 of Article V contains two grounds for refusal that the court of enforcement may take into account ex officio: the dispute not being arbitrable and the enforcement of the award being contrary to the public policy (ordre public) of the country of enforcement.
4. Public Policy (Ordre Public) Objection: The Most Frequently Invoked and Most Controversial Ground for Refusal
The most frequently invoked ground for refusal in the enforcement of foreign arbitral awards is the allegation of contravention of public policy. In recent years, the Court of Cassation has taken significant steps towards adopting the "international public policy" approach in interpreting the concept of public policy. According to this approach, the concept of public policy is limited not to the entirety of the mandatory provisions of domestic law, but only to the principles constituting the cornerstones of the Turkish legal system. This pro-enforcement approach adopted by the General Assembly of Civil Chambers of the Court of Cassation and through Decisions Unifying Case Law constitutes a significant development enhancing the practical effectiveness of foreign arbitral awards. According to the established jurisprudence of the 11th Civil Chamber of the Court of Cassation, the merits of the arbitral award cannot be reviewed (prohibition of révision au fond / revision yasağı); only the contravention of public policy by the outcomes may be evaluated; and such evaluation must be at the level of a concrete, serious, and undeniable infringement. Objections regarding interest rates, default damages, and attorney's fees are generally not accepted as constituting public policy violations.
5. Arbitrability and Limitations Under Turkish Law
Whether a dispute may be submitted to arbitration (objective arbitrability) is a critical criterion examined ex officio by the court at the enforcement stage. Under Turkish law, matters over which the parties cannot freely dispose (for example, family law, inheritance law, in rem rights over immovable property) are considered non-arbitrable. By contrast, commercial disputes, construction contracts, intellectual property disputes, and, under modern legal understanding, certain disputes in the areas of competition law, labour law, and consumer law are now considered arbitrable. The case law of the Court of Cassation on this matter is evolving in the direction of expanding the scope of arbitration.
6. Defective Service, Right of Defence, and Composition of the Arbitral Tribunal
Under Article V(1)(b), failure to give proper notice to a party in the arbitration process or violation of the right of defence constitutes a ground for refusal of enforcement. In this framework; the arbitration request reaching the party, being informed of hearings, being given the opportunity to present evidence, and the arbitral tribunal's award being notified to the party are fundamental guarantees. In examining allegations of defective service, the Court of Cassation considers both the procedural law of the seat of arbitration and the fundamental principles of Turkish procedural law together; it distinguishes between formal defects and actual violations of the right of defence. Non-compliance of the composition of the arbitral tribunal or the arbitration procedure with the arbitration agreement is also evaluated under Article V(1)(d) and is linked to the concrete prejudice of the parties.
7. Modern Trends: Pro-Enforcement Bias and Comparative Case Law
The doctrine and practice of international arbitration have adopted the "pro-enforcement bias" principle in the interpretation of the New York Convention. Under this principle, the grounds for refusal in Article V must be interpreted narrowly, presumptions must operate in favour of enforcement, and the practical effectiveness of arbitral awards must not be eroded by prolonged enforcement litigation. The practice of arbitration-friendly jurisdictions such as Singapore, Switzerland, England, and France is also instructive for Turkish courts. The Guide on the New York Convention prepared by the UNCITRAL Secretariat and the ICCA Yearbook Commercial Arbitration publications are fundamental resources for tracking comparative case law.
8. Comparison with ICSID Investment Arbitration Awards
Investment arbitration awards rendered under the ICSID Convention are subject to a sui generis enforcement regime. Under Article 54 of the ICSID Convention, such awards are directly enforceable in contracting states without being subject to any recognition procedure; the grounds for refusal in Article V of the New York Convention do not apply to ICSID awards. This difference shows that investment arbitration awards are under stronger enforcement protection compared to commercial arbitration awards. By contrast, investment arbitration awards rendered outside the ICSID framework (under UNCITRAL, SCC, or ICC rules) are subject to the New York Convention procedure.
9. Practical Recommendations and Enforcement Strategy
Critical steps for success in the enforcement of foreign arbitral awards in Türkiye include: (i) drafting the arbitration agreement in such a way that its validity can be confirmed at the enforcement stage, (ii) carefully preserving documents related to service of process and the right of defence during the arbitration, (iii) having an apostilled or consular-certified translation of the arbitral award ready, (iv) identifying the debtor's assets in Türkiye in advance, (v) requesting preliminary attachment prior to enforcement, and (vi) preparing arguments against potential public policy objections in advance.
