Extradition

Extradition is the formal process by which one State surrenders a person accused or convicted of an offence to another State for criminal prosecution or enforcement of a sentence. It is an important mechanism of international cooperation in combating cross-border crime while balancing State sovereignty, human rights and individual liberty.

Meaning

Extradition generally involves two States:

Requesting State → requests surrender

Requested State → considers the request

↓

Person → surrendered for prosecution or punishment

The State seeking the person’s surrender is called the requesting State, while the State in whose territory the person is located is called the requested State.

Object of Extradition

The primary objectives are:

• preventing criminals from escaping justice by crossing borders;
• enabling prosecution of persons accused of offences;
• enforcing criminal sentences;
• promoting international cooperation;
• preventing impunity for serious crimes.

Extradition and Territorial Sovereignty

A State exercises sovereignty over persons within its territory.

Therefore, one State cannot ordinarily enter another State’s territory and arrest a person there without lawful authority.

Extradition provides a lawful mechanism for cooperation between States.

Thus:

State A → wants person

Person located in State B

↓

State A cannot ordinarily simply arrest person in State B

↓

State A requests extradition from State B

Legal Basis of Extradition

Extradition may be based upon:

• bilateral extradition treaties;
• multilateral conventions;
• domestic legislation;
• reciprocity;
• other applicable international arrangements.

There is generally no universal customary rule requiring every State to extradite every person requested by another State.

The existence and terms of an extradition obligation depend upon the applicable legal framework.

Extradition Treaty

A bilateral extradition treaty is an agreement between two States establishing rules for surrendering persons.

It may specify:

• extraditable offences;
• evidence requirements;
• procedural requirements;
• grounds for refusal;
• political offence exceptions;
• speciality;
• nationality rules;
• human rights safeguards.

Dual Criminality

Dual criminality is a major principle of extradition.

The conduct for which extradition is requested must generally constitute an offence under the laws of both States.

For example:

Conduct → offence in State A

Same conduct → offence in State B

↓

Dual criminality satisfied

The exact formulation depends upon the applicable treaty.

Rule of Speciality

The rule of speciality provides that a person extradited for a particular offence should generally be prosecuted or punished only for that offence, or offences meeting the conditions permitted by the extradition arrangement.

The requesting State cannot ordinarily use extradition as a means of prosecuting the person for unrelated offences.

For example:

Extradition granted for Offence A

↓

Requesting State → prosecutes for Offence A

↓

Cannot ordinarily prosecute for unrelated Offence B

unless an applicable exception or consent exists.

Political Offence Exception

Traditionally, States have often refused extradition for political offences.

The rationale is that extradition should not be used to facilitate political persecution.

The scope of the political offence exception varies considerably between treaties and modern extradition law.

Serious crimes such as terrorism are increasingly excluded from the political offence exception under international conventions and extradition treaties.

Fiscal Offences

Historically, some States treated tax and other fiscal offences differently from ordinary crimes.

Modern extradition treaties increasingly provide for extradition concerning certain fiscal offences, subject to their specific provisions.

Military Offences

Purely military offences, such as certain disciplinary offences committed by members of armed forces, may be excluded from extradition treaties.

The exact rule depends upon the applicable treaty.

Extradition of Nationals

States differ concerning the extradition of their own nationals.

Some States permit extradition of nationals.

Others constitutionally or statutorily prohibit or restrict it.

Where extradition is refused because the person is a national, the State may in some circumstances prosecute the person domestically.

This is sometimes associated with the principle:

Aut dedere aut judicare

meaning:

“extradite or prosecute.”

The principle applies only where a relevant treaty or rule of International Law establishes such an obligation.

Extradition and Human Rights

Modern extradition law is strongly influenced by human rights considerations.

A State may refuse extradition where surrender would expose the person to serious violations of protected rights.

Relevant concerns may include:

• torture;
• cruel, inhuman or degrading treatment;
• arbitrary detention;
• denial of a fair trial;
• discriminatory prosecution;
• risk of persecution;
• death penalty in certain circumstances.

Non-Refoulement

The principle of non-refoulement may restrict extradition where surrender would expose a person to a prohibited risk.

This is particularly important in:

• refugee law;
• torture cases;
• serious human rights violations.

Torture and Extradition

States may be prohibited from extraditing a person where there are substantial grounds for believing that the person would face torture in the requesting State.

The Convention against Torture, 1984, is particularly important in this regard.

Its Article 3 prohibits returning or extraditing a person to another State where there are substantial grounds for believing that the person would be in danger of being subjected to torture.

Death Penalty

The death penalty can create extradition difficulties where:

Requested State → does not permit capital punishment

but

Requesting State → may execute the person

The requested State may require assurances that the death penalty will not be imposed or carried out.

The precise position depends upon applicable domestic and international law.

Political Persecution

Extradition may be refused where the request is genuinely intended to persecute a person because of:

• political opinion;
• race;
• religion;
• nationality;
• other protected characteristics.

Treaties may contain provisions permitting refusal where prosecution is discriminatory or politically motivated.

Prima Facie Case

Some extradition systems historically require the requesting State to establish a prima facie case against the person.

Under other modern treaty systems, especially those based on judicial cooperation, the evidentiary threshold may be different.

Therefore, the requirement depends upon the applicable extradition regime.

Evidence

The requesting State normally provides supporting material establishing the identity of the person and the basis for the request.

Requirements may include:

• arrest warrant;
• charging document;
• conviction;
• statement of facts;
• relevant evidence;
• applicable legal provisions.

The precise requirements vary by treaty and domestic law.

Extradition Procedure

A simplified extradition process may be represented as:

1. Offence committed

↓

2. Person located in another State

↓

3. Requesting State submits extradition request

↓

4. Requested State examines request

↓

5. Judicial/administrative proceedings

↓

6. Grounds for refusal considered

↓

7. Decision on extradition

↓

8. Surrender, if approved

Judicial and Executive Roles

Different States use different procedures.

Some systems give substantial authority to courts.

Others involve both:

• judicial determination;
• executive decision.

Therefore, extradition is often a combination of judicial and executive processes.

Provisional Arrest

A requesting State may seek provisional arrest before submitting the complete extradition documentation.

This prevents the person from escaping while the formal request is prepared.

The applicable treaty and domestic law determine:

• grounds;
• time limits;
• procedure;
• release conditions.

Extradition vs Deportation

These concepts must be distinguished.

Extradition

A person is surrendered to another State for:

• prosecution; or
• enforcement of a criminal sentence.

Deportation

A State removes a foreigner from its territory under its immigration law. Extradition Deportation Criminal cooperation Immigration measure Requested by another State Initiated by territorial State Purpose is prosecution/punishment Purpose is removal from territory Governed by treaties/domestic extradition law Governed primarily by immigration law

Extradition vs Expulsion

Expulsion is the removal of an alien from the territory of a State.

Extradition involves surrender to another State for criminal proceedings or punishment.

An extradition request may therefore be distinguished from an ordinary immigration removal order.

Extradition vs Rendition

Rendition is a broader term referring to the transfer or surrender of a person between jurisdictions.

Where a person is seized and transferred outside lawful extradition procedures, serious questions of sovereignty and International Law may arise.

Extradition vs Deportation: Important Exam Point

A State cannot necessarily avoid extradition safeguards simply by disguising a criminal surrender as an immigration measure.

Where the real purpose is to transfer a person to another State for criminal prosecution, the applicable international and domestic safeguards may become relevant.

Extradition and Refugees

A refugee may be subject to extradition proceedings, but refugee and human rights obligations can restrict surrender.

The requesting State must not use extradition to circumvent applicable protection against persecution or other prohibited treatment.

Extradition and Asylum

A person seeking asylum may raise concerns about extradition where the request is connected with persecution.

The authorities must consider applicable:

• refugee law;
• human rights law;
• extradition law.

Aut Dedere Aut Judicare

The principle aut dedere aut judicare means:

“Either extradite or prosecute.”

Under certain international conventions, a State that finds an alleged offender within its territory may have an obligation to:

Extradite the person

or

Submit the case for prosecution domestically

This principle does not automatically apply to every offence. Its application depends upon the relevant treaty or international legal rule.

Extradition and Universal Jurisdiction

Extradition can operate alongside universal jurisdiction.

For example:

Person accused of international crime

↓

Located in State A

↓

State B requests extradition

↓

State A may consider extradition

Alternatively, State A may prosecute under its own jurisdiction where applicable.

Extradition for International Crimes

Modern international cooperation increasingly permits extradition for serious crimes such as:

• genocide;
• war crimes;
• crimes against humanity;
• terrorism;
• torture;
• transnational organised crime.

The exact obligations depend upon the applicable treaty.

Human Rights and Fair Trial

A requested State may consider whether the person would receive a fair trial in the requesting State.

Concerns may include:

• independence of courts;
• access to legal representation;
• presumption of innocence;
• procedural fairness;
• arbitrary detention.

However, the precise threshold for refusing extradition depends upon the applicable legal framework.

Important Cases

Soering v. United Kingdom, 1989

The European Court of Human Rights held that extradition could violate Article 3 of the European Convention on Human Rights where the person faced a real risk of inhuman or degrading treatment in the requesting State.

The case is important for human rights limitations on extradition.

United States v. Alvarez-Machain, 1992

The US Supreme Court considered the circumstances surrounding the forcible abduction of a person from Mexico.

The case is important in discussions concerning extradition, abduction and jurisdiction.

LaGrand, 2001

The ICJ considered consular notification rights under the Vienna Convention on Consular Relations in the context of foreign nationals facing criminal proceedings.

Jadhav, 2019

The ICJ considered consular access and rights under the Vienna Convention on Consular Relations.

Extradition and India

In India, extradition is primarily governed by the Extradition Act, 1962, together with applicable extradition treaties and arrangements.

India may extradite or request extradition depending upon the applicable legal framework.

The Indian framework also contains safeguards concerning matters such as:

• extraditable offences;
• treaty arrangements;
• judicial inquiry;
• restrictions on surrender.

Important Principles of Extradition

The major principles can be remembered as:

Dual Criminality

Speciality

Political Offence Exception

Rule Against Double Jeopardy

Non-Refoulement / Human Rights Protection

Aut Dedere Aut Judicare where applicable

Double Jeopardy

The principle of double jeopardy may operate as a ground for refusing extradition where the person has already been finally tried or punished for the same offence, subject to the applicable legal framework.

This principle is also expressed through the concept of ne bis in idem.

Reciprocity

Some extradition arrangements operate partly on the basis of reciprocity, meaning States provide cooperation to each other on the expectation of corresponding cooperation.

However, treaty obligations may operate independently of general reciprocity.

Speciality vs Dual Criminality

These are frequently confused.

Dual criminality → conduct must generally be criminal in both States.

Speciality → prosecution is generally limited to the offence for which extradition was granted.

Conclusion

Extradition is an important mechanism of international criminal cooperation through which a State surrenders a person located within its territory to another State for prosecution or enforcement of a criminal sentence. Because extradition involves the exercise of sovereign authority by two States, it normally operates through treaties, domestic legislation or other applicable international arrangements. Important principles include dual criminality, under which the relevant conduct is generally criminal in both States, and the rule of speciality, which generally restricts prosecution to the offence for which extradition was granted. Traditional grounds for refusal include political offences, while modern extradition law increasingly incorporates safeguards based on human rights, non-refoulement and protection against torture or other serious mistreatment. The principle of aut dedere aut judicare may require a State, under particular treaties or international rules, either to extradite an alleged offender or submit the case for domestic prosecution. Extradition must also be distinguished from deportation and expulsion, which are primarily immigration measures. The Soering case is particularly important for the human-rights limitations on extradition. In India, the Extradition Act, 1962, together with applicable treaties and arrangements, provides the principal domestic framework. Thus, extradition represents a balance between international cooperation in combating crime, State sovereignty and protection of individual rights.
