Extradition: Challenges, and Methods
A Human Rights Perspective
I. Introduction: The Jurisprudential Tension
Extradition is the formal legal process by which one State (the requested State) surrenders a person to another State (the requesting State) for prosecution or punishment.
The core tension in extradition law is between sovereignty/security (the State’s duty to combat transnational crime and prevent impunity) and individual human rights (the duty to protect individuals from persecution or ill-treatment).
While there is no general obligation to extradite under Customary International Law (CIL) absent a treaty, the principle of aut dedere aut judicare (extradite or prosecute) has hardened into a binding obligation for jus cogens crimes (e.g., torture, genocide), as seen in the Convention Against Torture (CAT).
II. Methods of Extradition
While formal treaties are the gold standard, states increasingly resort to alternative (and controversial) methods to bypass procedural safeguards.
1. Treaty-Based Extradition
- Bilateral Treaties: The traditional method, strictly defined by terms (e.g., US-UK Extradition Treaty 2003).
- Multilateral Conventions: E.g., The European Arrest Warrant (EAW) which replaces “extradition” with “surrender” between EU states, removing the political executive from the decision-making process to expedite returns.
2. Ad-Hoc Arrangements
In the absence of a treaty, states may agree to extradite on a case-by-case basis based on comity and reciprocity.
3. “Disguised Extradition” (Deportation/Expulsion)
- Critique: States often use immigration powers (deportation) to remove a suspect to a state that wants them, bypassing the rigorous human rights checks of extradition courts.
- Case Law: Boitano v. USA (courts look at the “dominant purpose” of the removal). If the purpose is rendition rather than immigration control, it is an abuse of process.
4. Extraordinary Rendition
The state-sponsored, extra-legal transfer of persons from one country to another (often for torture/interrogation), completely bypassing the judicial system. This is a flagrant violation of international human rights law.
III. International Norms: The Human Rights “Bars” to Extradition
Modern extradition law is less about administrative cooperation and more about human rights adjudication. The following are the primary barriers to extradition:
1. The Absolute Bar: Torture and Non-Refoulement
Under Article 3 of the ECHR and Article 3 of CAT, a state cannot extradite a person where there are substantial grounds for believing they would be in danger of being subjected to torture.
- Landmark Case:Soering v. UK (1989)
- Facts: Soering faced extradition to the US (Virginia) for capital murder.
- Ratio: The European Court of Human Rights (ECtHR) held that while the death penalty itself was not then outlawed, the “Death Row Phenomenon” (years of mental anguish awaiting execution) constituted inhuman and degrading treatment. Extradition was refused.
- Significance: It extended state responsibility extraterritorially. The UK becomes responsible for the foreseeable ill-treatment the fugitive suffers after leaving its soil.
2. The Fair Trial Bar (Article 6 ECHR / ICCPR Art 14)
Extradition can be refused if the fugitive risks a “flagrant denial of justice” in the requesting state.
- Landmark Case:Othman (Abu Qatada) v. UK (2012)
- Ratio: The ECtHR blocked the deportation of Abu Qatada to Jordan because evidence obtained via the torture of third parties would likely be used against him in his trial.
- Significance: This set a high threshold. Mere “irregularities” in a foreign trial are not enough; the breach must be “flagrant” (destroying the essence of the right).
3. The Death Penalty Exception
Most abolitionist states (EU, Canada, Australia) refuse extradition to retentionist states (USA, China) unless “satisfactory assurances” are given that the death penalty will not be sought or carried out.
- Case Law: Judge v. Canada (UN Human Rights Committee): Extraditing a person to face the death penalty without assurances violates the right to life (ICCPR).
4. The Political Offense Exception
Historically, states refused to extradite political dissidents.
- Modern Erosion: In the age of terrorism, this exception has been severely curtailed. The Suppression of Terrorism Convention explicitly removes violent acts (bombing, hijacking) from being considered “political offenses.”
IV. Contemporary Challenges
1. The Dilemma of “Diplomatic Assurances”
When a state wants to extradite a suspect to a country known for torture (e.g., Jordan, Libya), they often seek “Diplomatic Assurances” (a promise: “We promise we won’t torture this specific guy“).
- Human Rights Critique: These are often “fig leaves” used to circumvent non-refoulement obligations. If a state tortures generally, a paper promise is legally worthless.
- Judicial View: In Othman, the court accepted assurances were given in good faith but still blocked removal on fair trial grounds.
2. Transnational Terrorism vs. Rights
Post-9/11, extradition laws were expedited (e.g., UK Extradition Act 2003). The challenge is ensuring that “fast-track” procedures do not erode judicial oversight.
- Issue: The “trust” model (e.g., EAW) assumes all partner states have equal human rights standards, which is often factually incorrect (e.g., prison conditions in Hungary vs. Sweden).
3. Politicization of the Judiciary
- Case Study:Julian Assange
- The Assange case highlighted the complexity of the “political offense” exception and the use of the Espionage Act. His defense argued extradition would be oppressive due to his mental health (Section 91, UK Extradition Act) and the risk of suicide in US “SAMs” (Special Administrative Measures) prison conditions.
- Outcome: Extradition was initially blocked on health grounds, then allowed after US assurances on prison conditions, before eventually ending in a plea deal. It illustrates how medical/health grounds have become a primary defense where political arguments fail.
V. Summary for Exams
| Concept | Key Case / Principle | Significance |
| Non-Refoulement | Soering v UK (1989) | Extraterritorial responsibility for torture/ill-treatment. |
| Fair Trial | Othman (Abu Qatada) | “Flagrant denial of justice” bars extradition. |
| Assurances | Chahal v UK | Assurances do not absolve the sending state of risk assessment. |
| Methods | Boitano v US | Distinguishing “Disguised Extradition” from lawful deportation. |
Conclusion:
From a human rights perspective, extradition is no longer a sovereign prerogative but a qualified power. The requesting State must prove not only the criminality of the act (Double Criminality) but also the human rights compliance of its own judicial and penal systems.
