One of the most important issues in private international law is determining which state’s courts have jurisdiction over disputes involving a foreign element. Today, due to people living in different countries, the rapid growth of international trade, cross-border activities of companies, and increasing legal relationships between individuals of different nationalities, it has become very common for a single dispute to be connected to more than one legal system.
This naturally raises the following question:
“Which country’s courts will hear this case?”
Jurisdiction rules in private international law provide the answer to this question. These rules determine which state’s courts are competent to hear a dispute and thereby ensure order in international legal relations.
In Turkish law, international jurisdiction rules are mainly regulated under Law No. 5718 on Private International Law and International Civil Procedure (MÖHÜK). Whether Turkish courts have jurisdiction in foreign-related cases is assessed under this framework.
In this article, we will examine the concept of international jurisdiction, the MÖHÜK system, general and special jurisdiction rules, jurisdiction agreements, exclusive jurisdiction, and practical issues in detail.
What Is International Jurisdiction?
International jurisdiction refers to the authority of a state’s courts to hear disputes involving a foreign element.
In other words, it determines whether Turkish courts can adjudicate a case containing a foreign element.
It is not only about which court within a country is competent, but also about which state has judicial authority.
For example:
- Divorce cases involving a German citizen living in Turkey
- Commercial disputes between French and Turkish companies
- Inheritance cases involving foreign property
- International transport contracts
In all these situations, the question of international jurisdiction arises.
Importance of International Jurisdiction
Jurisdiction rules are not merely technical rules; they are directly connected to state sovereignty.
The question of which courts may hear a dispute defines the limits of a state’s judicial power.
Jurisdiction rules:
- Ensure legal certainty
- Prevent conflicts of jurisdiction
- Facilitate international trade
- Increase predictability for parties
In today’s globalized world, jurisdiction rules have become increasingly important.
Jurisdiction System under MÖHÜK
In Turkish law, international jurisdiction is primarily regulated under MÖHÜK.
According to MÖHÜK, Turkish courts generally rely on domestic territorial jurisdiction rules when determining international jurisdiction.
This means that the rules in the Code of Civil Procedure (HMK) are also relevant in international cases.
However, in certain cases, specific international jurisdiction rules are provided.
General Jurisdiction Rule
The general rule in private international law is that the court of the defendant’s domicile has jurisdiction.
If the defendant is domiciled in Turkey, Turkish courts may hear the case.
If the defendant has no domicile in Turkey, factors such as:
- Habitual residence
- Location of assets
- Temporary presence
may be considered.
This system is based on the protection of the defendant.
Concept of Domicile
Domicile is one of the most important connecting factors in jurisdiction rules.
It refers to:
- The place where a person lives with the intention of permanence
- The legal center of a person’s life
For companies, the registered office or headquarters is generally considered.
For example, a company with headquarters in Istanbul may be subject to Turkish jurisdiction even if it is foreign-owned.
Special Jurisdiction Rules
MÖHÜK provides special jurisdiction rules for certain types of disputes.
These rules vary depending on the nature of the dispute.
Contractual Disputes
The court of the place of performance may have jurisdiction.
For example, in an international sales contract where delivery is to be made in Turkey, Turkish courts may have jurisdiction.
Tort (Unlawful Act) Cases
The court of the place where the tort occurred may have jurisdiction.
In cases such as online defamation or international trademark infringement, the place of harm becomes important.
Consumer Disputes
Special protective jurisdiction rules may apply to consumers.
The courts of the consumer’s domicile may be competent.
Employment Disputes
To protect employees, the place where the employee habitually works may be used as a jurisdictional factor.
What Is a Jurisdiction Agreement?
In international commercial relations, parties may agree in advance on which country’s courts will have jurisdiction.
This is called a jurisdiction agreement.
For example:
“Courts of Istanbul shall have jurisdiction over disputes arising from this contract.”
Such agreements are commonly used in:
- International trade
- Maritime contracts
- Financial agreements
- Transport contracts
Requirements of Jurisdiction Agreements
Written Form
Jurisdiction agreements are generally required to be in writing.
Specific Dispute or Relationship
They must relate to a specific legal relationship.
Commercial Nature
In Turkish law, jurisdiction agreements are often allowed primarily in commercial disputes.
What Is Exclusive Jurisdiction?
In some cases, only certain courts have jurisdiction. This is called exclusive jurisdiction.
Where exclusive jurisdiction applies, decisions of foreign courts may not be recognized or enforced in Turkey.
Exclusive Jurisdiction under Turkish Law
Real Property Disputes
Turkish courts have exclusive jurisdiction over rights relating to immovable property located in Turkey.
Enforcement Proceedings
Turkish courts have exclusive jurisdiction over enforcement proceedings carried out in Turkey.
Company Disputes
Courts at the company’s registered office may have exclusive jurisdiction in certain cases.
Jurisdiction and Public Policy
International jurisdiction rules are closely linked to public policy.
Fundamental principles such as:
- Right to a fair trial
- Legal certainty
- Protection of defense rights
play an important role in shaping jurisdiction rules.
For example, a jurisdiction choice completely unrelated to the dispute may be considered invalid in certain cases.
Jurisdiction and Arbitration
In international commercial disputes, parties often prefer arbitration instead of state courts.
With an arbitration agreement, disputes are resolved by arbitrators rather than courts.
Arbitration is especially common in:
- International trade
- Construction projects
- Energy investments
- Maritime disputes
European Union Jurisdiction System
In the European Union, jurisdiction rules are regulated under the Brussels Regulation.
This system aims to:
- Ensure free movement of judgments
- Reduce jurisdiction conflicts
- Enhance legal certainty
Although Turkish law is not identical, there are similarities.
Conflicts of Jurisdiction
Sometimes more than one country’s courts may claim jurisdiction over the same dispute.
This leads to conflicts of jurisdiction.
Examples include:
- Parties located in different countries
- Contracts signed abroad
- Harm occurring in multiple jurisdictions
Forum Shopping
Forum shopping occurs when parties try to choose the most favorable jurisdiction.
For example, parties may prefer:
- Lower compensation risk
- Faster proceedings
- More favorable procedural rules
This is a controversial issue in private international law.
Jurisdiction in Digital Disputes
With technological development, new jurisdiction issues have emerged.
Examples include:
- Social media defamation
- Cross-border e-commerce
- Digital copyright infringement
- Data protection disputes
Determining jurisdiction in such cases is increasingly complex.
Approach of the Court of Cassation (Yargıtay)
The Court of Cassation considers:
- Protection of the defendant
- Right to a fair trial
- Public policy
- Validity of jurisdiction agreements
especially carefully in its decisions.
Jurisdiction vs. Competence
These two concepts are different:
- Competence (subject-matter jurisdiction): which type of court hears the case
- Jurisdiction: which court geographically or internationally hears the case
In private international law, the main issue is allocation of jurisdiction between states.
Common Jurisdiction Issues in Practice
Frequently encountered cases include:
- Foreign divorce cases
- International commercial contracts
- E-commerce disputes
- Employment contracts
- Maritime law disputes
- Intellectual property disputes
With the growth of international trade, commercial jurisdiction disputes are increasing rapidly.
Conclusion
Jurisdiction rules in private international law determine which state’s courts have authority over disputes involving a foreign element.
In Turkish law, international jurisdiction is largely regulated under MÖHÜK. Through general jurisdiction rules, special jurisdiction provisions, jurisdiction agreements, and exclusive jurisdiction rules, order is maintained in international legal relations.
Due to globalization, digitalization, and increasing cross-border relations, jurisdiction rules have become more important than ever.
Therefore, understanding the system of international jurisdiction is essential for law students, practitioners, and legal professionals working in private international law.
