International extradition law has become one of the most dynamic and strategically significant fields of modern international criminal law. In recent years, rapid globalization of financial systems, cryptocurrency transactions, international trade, sanctions enforcement, cybercrime investigations, and transnational anti-money laundering frameworks has substantially increased cooperation among prosecutorial authorities, law enforcement agencies, financial intelligence units, and judicial institutions worldwide. 

Today, businesspersons, executives, investors, financial intermediaries, politically exposed individuals, and multinational companies may face criminal exposure simultaneously in multiple jurisdictions. International criminal investigations increasingly involve allegations concerning:

• fraud,
• money laundering,
• corruption,
• sanctions violations,
• tax offences,
• cybercrime,
• export control breaches,
• organized financial misconduct.

As a result, extradition proceedings have evolved far beyond traditional criminal surrender mechanisms. Modern extradition cases now involve complex interactions among:

• criminal law,
• constitutional protections,
• international treaties,
• human rights law,
• diplomatic relations,
• financial compliance frameworks,
• international judicial cooperation mechanisms.

Türkiye occupies a particularly important position within this evolving international legal landscape. Due to its geopolitical location, economic significance, regional diplomatic role, and extensive international relations, Türkiye frequently becomes involved in extradition proceedings concerning:

• financial crimes,
• organized crime,
• terrorism-related allegations,
• politically sensitive matters,
• INTERPOL Red Notices,
• international fraud investigations.

The increasing number of cross-border investigations involving Turkish nationals and international businesspersons demonstrates the growing practical significance of extradition law in Türkiye. High-profile cases involving allegations of international fraud and money laundering have attracted significant international attention and have highlighted the legal complexity of extradition proceedings involving Turkish citizens and residents. One of the most widely discussed examples concerned the extradition request involving Turkish businessman Sezgin Baran Korkmaz in connection with allegations brought by United States authorities concerning large-scale financial fraud and money laundering activities. These developments demonstrate that extradition proceedings may rapidly transform into highly sophisticated international legal disputes involving:

• provisional arrests,
• INTERPOL notices,
• diplomatic negotiations,
• parallel criminal investigations,
• financial asset tracing,
• human rights litigation,
• constitutional review mechanisms.

What Is Extradition?

Extradition is the formal legal process through which one sovereign state requests another state to surrender an individual accused or convicted of a criminal offence. The purpose of extradition may involve:

• prosecution for alleged criminal conduct; or
• enforcement of a criminal sentence already imposed.

Extradition differs fundamentally from deportation or administrative removal procedures. Unlike immigration-related expulsion measures, extradition proceedings require judicial review and are governed by international treaties, domestic legislation, and principles of international criminal law. The European Convention on Extradition of 1957 remains one of the most important multilateral extradition treaties governing extradition cooperation across Europe. Türkiye is a party to this Convention.

Fundamental Principles of Extradition Law

Modern extradition law is governed by several core principles designed to protect both state sovereignty and individual rights.

Double Criminality Principle

Extradition generally requires that the alleged conduct constitute a criminal offence under both:

• the requesting state’s law; and
• the requested state’s law.

Turkish law and international treaties recognize this principle as a fundamental safeguard.

Specialty Principle

Under the specialty principle, an extradited person may generally be prosecuted only for the offences for which extradition was granted. This principle protects individuals from expanded prosecutions after surrender.

Political Offence Exception

One of the most important safeguards in extradition law concerns political offences. Extradition may be refused where:

• the request is politically motivated,
• the offence is regarded as political in nature,
• prosecution may involve persecution based on political opinion.

Political offence exceptions frequently arise in extradition matters involving:

• dissidents,
• opposition figures,
• terrorism allegations,
• geopolitical disputes.

Human Rights Protections

Human rights considerations increasingly influence extradition proceedings globally. Extradition may be refused where there is substantial risk of:

• torture,
• inhuman treatment,
• unfair trial,
• discriminatory prosecution,
• politically motivated punishment.

The jurisprudence of the European Court of Human Rights has become particularly influential in this area.

Legal Framework Governing Extradition in Türkiye

Law No. 6706 on International Judicial Cooperation in Criminal Matters

The principal legislation governing extradition in Türkiye is:

• Law No. 6706 on International Judicial Cooperation in Criminal Matters.

This law regulates:

• extradition procedures,
• provisional arrest,
• mutual legal assistance,
• transfer of sentenced persons,
• international criminal cooperation mechanisms.

The legislation modernized Türkiye’s international criminal cooperation framework and established detailed procedural rules concerning extradition proceedings.

Constitutional Protections

Article 38 of the Turkish Constitution historically provided strong protections regarding extradition of Turkish nationals. Turkish constitutional principles also emphasize:

• legality,
• judicial review,
• fair trial rights,
• proportionality,
• human dignity protections.

Extradition proceedings in Türkiye therefore involve both:

• judicial review; and
• executive evaluation.

International Treaties Applicable to Türkiye

Türkiye participates in multiple international extradition and judicial cooperation mechanisms.

These include:

• the European Convention on Extradition,
• Additional Protocols to the Convention,
• bilateral extradition treaties,
• United Nations conventions concerning organized crime, corruption, and terrorism financing.

Türkiye also actively cooperates with:

• Interpol,
• foreign prosecutorial authorities,
• financial intelligence units,
• international law enforcement agencies.

The Council of Europe materials concerning Türkiye’s extradition procedures confirm that extradition requests are evaluated under both domestic legislation and international treaty obligations.

Extradition Procedure in Türkiye

Competent Courts

Under Turkish law, extradition requests are examined by the competent Heavy Criminal Court located where the requested person is found. If the individual’s location cannot be determined, Ankara courts may become competent.

Provisional Arrest

In urgent situations, provisional arrest may occur before the formal extradition documentation is completed. According to Council of Europe materials concerning Türkiye’s procedures, provisional arrest periods may extend from 18 to 40 days pending submission of full extradition documents. Provisional arrest requests often rely upon:

• INTERPOL Red Notices,
• diplomatic communications,
• urgent judicial cooperation mechanisms.

Judicial Review

Turkish courts examine:

• admissibility of the request,
• treaty compatibility,
• double criminality,
• human rights considerations,
• procedural legality.

The court does not determine guilt or innocence concerning the underlying allegations. Instead, the court evaluates whether legal conditions for extradition are satisfied.

Executive Approval

Even where a Turkish court finds extradition legally admissible, the extradition process requires executive approval. Under Article 19 of Law No. 6706:

• extradition execution depends upon the proposal of the Minister of Justice and approval of the President of the Republic following consultation with relevant ministries.

This demonstrates that extradition in Türkiye contains both:

• judicial dimensions; and
• sovereign executive considerations.

INTERPOL Red Notices and International Arrest Risks

Modern extradition proceedings frequently begin with:

• INTERPOL Red Notices,
• international arrest alerts,
• provisional detention requests.

An INTERPOL Red Notice is not technically an international arrest warrant. However, it may create serious practical consequences including:

• airport detention,
• travel restrictions,
• banking and compliance complications,
• reputational harm,
• provisional arrest proceedings.

INTERPOL-related proceedings frequently overlap with:

• extradition requests,
• sanctions investigations,
• financial crime allegations,
• politically sensitive prosecutions.

International practice demonstrates increasing use of INTERPOL mechanisms in cases involving:

• money laundering,
• cybercrime,
• fraud,
• organized crime.

Legal remedies may exist before the:

• Commission for the Control of INTERPOL’s Files (CCF).

European Arrest Warrant and Türkiye

The European Arrest Warrant (EAW) system replaced traditional extradition procedures among European Union Member States with a judicial surrender mechanism based on:

• mutual recognition,
• judicial cooperation,
• accelerated procedures.

Türkiye is not a member of the European Union and therefore does not directly participate in the EAW system. Nevertheless, Turkish nationals located in EU countries may still become subject to:

• surrender requests,
• extradition proceedings,
• provisional arrests within EU jurisdictions.

The distinction between:

• classical extradition; and
• EAW surrender procedures

remains highly important in cross-border criminal defense strategy.

Human Rights and Extradition Defense

Human rights law has become one of the most important components of modern extradition defense. Courts increasingly examine whether extradition may expose individuals to:

• torture,
• politically motivated prosecution,
• discriminatory treatment,
• unfair trials,
• prison overcrowding,
• violations of procedural guarantees.

The jurisprudence of:

• European Court of Human Rights,
• Court of Justice of the European Union

has significantly shaped extradition standards across Europe. Human rights arguments may become particularly relevant where extradition requests involve:

• politically sensitive allegations,
• terrorism accusations,
• geopolitical disputes,
• refugee status,
• sanctions-related proceedings.

Recent European jurisprudence involving Turkish extradition requests demonstrates that courts may carefully scrutinize human rights implications before approving surrender.

Extradition in Financial Crime and Business Crime Cases

Modern extradition proceedings increasingly concern:

• international fraud,
• money laundering,
• cryptocurrency investigations,
• corruption allegations,
• sanctions violations,
• export control offences,
• cybercrime,
• tax investigations.

International authorities increasingly cooperate through:

• anti-money laundering systems,
• banking compliance frameworks,
• financial intelligence sharing,
• asset tracing operations,
• international sanctions enforcement.

This trend has substantially increased legal exposure for:

• multinational executives,
• cross-border investors,
• cryptocurrency businesses,
• financial intermediaries,
• internationally active entrepreneurs.

Defense Strategies in Extradition Proceedings

Effective extradition defense requires immediate and coordinated legal intervention. Potential defense approaches may include:

• procedural objections,
• treaty interpretation arguments,
• constitutional protections,
• political offence defenses,
• proportionality challenges,
• human rights litigation,
• evidentiary objections.

Successful extradition defense frequently requires coordination among:

• criminal defense counsel,
• foreign lawyers,
• human rights specialists,
• compliance professionals,
• international legal experts.

Early legal intervention is particularly important because:

• provisional arrests may occur unexpectedly,
• international travel risks may escalate rapidly,
• parallel investigations may emerge in multiple jurisdictions simultaneously.
