The European Convention on Extradition is a key legal instrument that has shaped the extradition process between European nations for decades. This article will delve into the origins, aims, and key provisions of this important treaty, as well as its impact on international cooperation in criminal matters. By understanding the European Convention on Extradition, one can better appreciate the significance of extradition as a tool for fighting cross-border crime and promoting justice in the European continent.

Introduction to the European Convention on Extradition

The European Convention on Extradition is a multilateral treaty that establishes a framework for extradition between its member states. It was drafted by the Council of Europe and opened for signature on December 13, 1957. The Convention entered into force on April 18, 1960, and has since been ratified by nearly all Council of Europe member states, as well as several non-European countries.

The main purpose of the Convention is to streamline and simplify the extradition process between its signatories. It does so by setting out clear provisions on the types of offenses that are extraditable, the procedures to be followed, and the exceptions that may apply. This facilitates cooperation between countries in the fight against crime and enhances the ability of states to bring criminals to justice.

Historical Background and Aims

The European Convention on Extradition was developed in response to the need for greater cooperation between European nations in the aftermath of World War II. The conflict had demonstrated the limitations of existing extradition arrangements, which were often based on bilateral treaties that varied widely in their provisions.

The Council of Europe, established in 1949 to promote unity and cooperation among European countries, took on the task of drafting a comprehensive extradition treaty. The resulting Convention aimed to:

  • Harmonize the extradition process among European nations
  • Facilitate the swift and efficient surrender of persons accused or convicted of crimes
  • Strengthen the rule of law and respect for human rights in extradition proceedings
  • Promote international cooperation in the fight against transnational crime

Key Provisions

The European Convention on Extradition sets out a range of provisions that govern the extradition process between its member states. These can be broadly grouped into three categories: grounds for extradition, extradition procedures, and exceptions and refusals.

Grounds for Extradition

The Convention establishes a set of criteria that must be met for an offense to be considered extraditable. These include:

  1. Dual criminality: The offense in question must be punishable under the laws of both the requesting and requested states, with a minimum penalty of at least one year’s imprisonment.
  2. Political offenses exception: Extradition is not granted for offenses deemed to be of a political nature or when it is believed that the request is made for political purposes.
  3. Military offenses exception: Extradition is not granted for offenses that are purely military in nature.

The Convention also provides a non-exhaustive list of offenses that should be considered extraditable, including crimes like murder, kidnapping, and drug trafficking.

Extradition Procedures

The European Convention on Extradition sets out a clear procedure for handling extradition requests between member states. Key steps in this process include:

  1. Submission of a request: The requesting state must submit a formal written request for extradition to the requested state, accompanied by relevant documentation, such as an arrest warrant and a description of the alleged offense.
  2. Verification of information: The requested state must verify that the information provided meets the requirements of the Convention, including the dual criminality requirement.
  3. Arrest and detention: If the requested state agrees to the extradition, it may arrest and detain the person sought, pending the final decision on the request.
  4. Judicial review: The requested state’s judicial authorities must review the extradition request to ensure it complies with the provisions of the Convention and domestic law.
  5. Surrender: If the extradition request is approved, the requested state must surrender the person sought to the requesting state within a specified time frame.

Exceptions and Refusals

The Convention recognizes that there may be circumstances in which extradition should not be granted. These exceptions and refusals include:

  1. Human rights considerations: Extradition may be refused if there are substantial grounds for believing that the person sought would be at risk of torture, inhuman or degrading treatment, or other violations of their human rights in the requesting state.
  2. Nationality exception: A requested state may refuse to extradite its own nationals, though it may be required to prosecute the individual domestically for the alleged offense.
  3. Non bis in idem (double jeopardy) principle: Extradition may be refused if the person sought has already been tried or punished for the same offense in the requested state.
  4. Statute of limitations: Extradition may be refused if the prosecution or punishment of the alleged offense is barred by the statute of limitations in either the requesting or requested state.
  5. Amnesty: If the requested state has granted amnesty for the alleged offense, it may refuse to extradite the person sought.

Impact on International Cooperation

Since its inception, the European Convention on Extradition has played a crucial role in promoting international cooperation in criminal matters among European nations. By providing a standardized framework for extradition, the Convention has made it easier for countries to collaborate in the fight against cross-border crime and deliver justice to victims.

In addition to facilitating extradition among its member states, the Convention has also served as a model for other regional and international extradition agreements. For example, the European Union’s Framework Decision on the European Arrest Warrant, which has streamlined and expedited the extradition process among EU member states, was partly inspired by the provisions of the European Convention on Extradition.

Furthermore, the Convention has had a positive impact on the respect for human rights in extradition proceedings. By setting out clear exceptions and refusals based on human rights considerations, the Convention has helped to ensure that the extradition process is conducted in a manner that is consistent with the fundamental principles of justice and the rule of law.


The European Convention on Extradition has proven to be a vital instrument in fostering cooperation among European nations in the pursuit of justice and the fight against transnational crime. By establishing clear grounds for extradition, streamlining procedures, and setting out exceptions and refusals based on human rights considerations, the Convention has not only facilitated the extradition process but also helped to ensure that it is conducted in a manner that respects the rule of law and human rights.

As the world continues to confront the challenges posed by cross-border crime, the European Convention on Extradition remains a key foundation for international cooperation in criminal matters. By understanding the provisions and aims of this important treaty, one can better appreciate its enduring significance in promoting justice and security in the European continent and beyond.
