Extradition law is a crucial aspect of international law enforcement cooperation. It’s the process of one country handing over a person accused or convicted of a crime to another country where they are to be tried or serve their sentence. This article will delve into the details of extradition law, including its history, key principles, and the legal procedures involved. We’ll also look at some of the most high-profile extradition cases in recent years.

History of Extradition Law

The concept of extradition has existed for centuries. Ancient societies, such as the Egyptians, Hittites, and Mesopotamians, already practiced the delivery of fugitives to the requesting jurisdiction. In medieval Europe, extradition arrangements often occurred between monarchs, who agreed to surrender criminals to one another for trial or punishment.

One of the earliest formal extradition treaties dates back to the 13th century, between England and France. This treaty provided for the extradition of offenders who committed serious crimes, such as murder or theft. Since then, extradition has evolved into an integral part of international cooperation in criminal matters.

Extradition Treaties and Agreements

Extradition is generally governed by bilateral or multilateral treaties between countries. These treaties outline the conditions under which an individual may be extradited, the types of crimes for which extradition is permitted, and the procedures to be followed in extradition cases. Some well-known multilateral extradition agreements include the European Arrest Warrant and the Inter-American Convention on Extradition.

Nations that do not have extradition treaties with one another can still engage in case-by-case extradition arrangements called “ad hoc” extraditions. These extraditions are based on mutual consent and often involve diplomatic negotiations between the countries involved.

Key Principles of Extradition Law

Several key principles underpin extradition law. These principles help ensure that the process is fair, respects human rights, and serves the interests of justice.

Dual Criminality

Dual criminality is a fundamental requirement in most extradition treaties. This principle means that the conduct alleged against the person sought must be considered a crime in both the requesting and requested countries. If the conduct is not criminal in the requested country, extradition is typically denied.


The principle of speciality dictates that the person extradited can only be tried, punished, or detained for the specific crime for which they were extradited. This ensures that individuals are not subjected to prosecution for unrelated offenses after their extradition.

Non-Extradition for Political Crimes

Many extradition treaties provide an exception for political crimes. This principle recognizes that people who commit acts of political dissent or opposition should not be extradited for fear of persecution. However, defining a “political crime” can be complex, and countries may have different interpretations.

Non-Extradition of Nationals

Some countries refuse to extradite their own citizens, based on constitutional or policy grounds. This principle is not universally applied, and many countries do extradite their own nationals if the conditions of the treaty are met.

Extradition Process and Legal Procedures

The extradition process typically begins when the requesting country submits a formal request for extradition to the requested country. This request must include evidence that establishes probable cause to believe that the person sought has committed the alleged crime.

Arrest and Detention

Once the requested country has received the extradition request, it may issue a warrant for the arrest of the person sought. After arrest, the individual may be detained pending the outcome of the extradition proceedings, although in some cases, they may be released on bail.

Extradition Hearing

An extradition hearing is held to determine whether the extradition request meets the requirements of the applicable treaty and whether the person sought is the same individual named in the request. The hearing does not determine the guilt or innocence of the person sought.

Judicial Review and Appeals

If the extradition request is granted, the person sought may have the right to appeal the decision or seek judicial review. This process allows a higher court to review the legality of the extradition decision.

Surrender to the Requesting Country

If the extradition request is ultimately approved and all appeals have been exhausted, the person sought will be surrendered to the requesting country, where they will face trial or serve their sentence for the alleged crime.

Controversial Extradition Cases

Throughout history, there have been several high-profile and controversial extradition cases. These cases often highlight the complexities and challenges involved in the extradition process.

Julian Assange

Julian Assange, the founder of WikiLeaks, has been at the center of a lengthy extradition battle between the United States and the United Kingdom. The U.S. has sought Assange’s extradition on charges related to the publication of classified documents. Assange’s legal team has argued that the charges are politically motivated and that his extradition would violate his human rights.

Edward Snowden

Edward Snowden, a former National Security Agency (NSA) contractor, leaked classified information detailing the U.S. government’s mass surveillance programs in 2013. Snowden fled to Russia, where he was granted temporary asylum and later permanent residency. The U.S. has charged Snowden with espionage and theft of government property, but Russia has refused to extradite him.

Roman Polanski

Film director Roman Polanski has been the subject of extradition attempts by the United States since he fled the country in 1978 to avoid sentencing for a sexual assault conviction. Polanski has lived primarily in France, which does not extradite its citizens, and Switzerland, which rejected a U.S. extradition request in 2010.


Extradition law plays a vital role in international cooperation on criminal matters. While the process can be complex and sometimes controversial, it is essential for bringing individuals to justice and ensuring that they do not evade the legal consequences of their actions. As global interconnectivity continues to increase, it is crucial for countries to have effective extradition laws and agreements in place to maintain the rule of law and promote international justice.

By understanding the key principles, legal procedures, and historical context of extradition law, we can better appreciate its significance as a tool for global law enforcement cooperation. With ongoing efforts to improve and streamline the extradition process, countries can continue to work together to combat cross-border crime and ensure that justice is served.
