Extradition Law and Policy in the UK

Extradition Proceedings (UK)

Extradition is a complex yet crucial aspect of international law. It facilitates the transfer of individuals between countries for legal purposes, typically to face criminal proceedings or to serve a sentence. Although the UK’s Extradition Act 2003 provides the foundational framework for extradition proceedings in the UK, the landscape has witnessed significant shifts in the post-Brexit era.

The importance of understanding the law for individuals potentially subject to extradition cannot be overstated. This knowledge not only equips individuals with the tools to navigate complex processes but also empowers them to safeguard their rights and ensure fair treatment.

In this comprehensive guide, we will explore nuances of the UK’s extradition laws, how human rights intersect with extradition requests and the protections available to individuals. 

What Does Extradition Mean?

Extradition is the formal process whereby one jurisdiction or country requests and obtains the surrender of an individual to face criminal proceedings or serve a sentence for an offence committed within the requesting country’s jurisdiction. It operates based on treaties, conventions, or bilateral accords between nations.  

The principle of extradition is rooted in the idea of international cooperation for the administration of justice. Without an effective extradition system, individuals could potentially commit crimes in one country and then simply flee to another, evading any legal consequences. This would sabotage the rule of law and allow countries to inadvertently become safe havens for criminals.

The UK maintains extradition relationships with over 100 territories globally, established through various multilateral conventions and bilateral extradition treaties. Even if the UK might not have a formal extradition treaty or arrangement with a specific territory, that territory can still forward an extradition request to the UK. Such incoming requests are directed to the UKCA, and then it is up to the Secretary of State to determine if ‘special extradition arrangements’ should be established.

The Extradition Act 2003

The Extradition Act 2003 serves as the primary legislation governing the extradition of individuals to and from the United Kingdom. It provides a structured framework detailing the process and circumstances under which an individual can be extradited. The Act is divided into various parts, but two of its primary divisions concern categorising territories for extradition purposes: Category 1 territories and Category 2 territories.

The categories here signify the distinctions between different groups of countries or territories with which the UK has extradition arrangements. Each category follows its own set of procedures, requirements, and criteria for the extradition process.

Category 1 Territories

These territories are primarily comprised of the European Economic Area (EEA) countries. Extradition requests from Category 1 territories previously operated under the European Arrest Warrant (EAW) system, but after Brexit, it’s not in action anymore. The UK and EU instituted a new extradition agreement on 1 January 2021.

The territories designated as ‘category 1 territories’ under the Extradition Act 2003 (Part 1) are EU nations like Austria, Belgium, France, Germany, and Spain, among others. Extradition between the UK and these territories obeys a set protocol.

Category 2 Territories

This category covers all other territories with which the UK has extradition relations outside the EU. The extradition process for Category 2 territories is typically more involved. The state requesting the extradition must often provide substantial evidence to back its request. 

Category 2 territories are separated into Type A and Type B. Type A countries can request extradition without the need for prima facie (a Latin expression meaning at first sight or based on first impression) evidence supporting their request. But, Type B countries are bound to deliver the required evidence.

In both categories, the proceedings must align with the European Convention on Human Rights, and the rights of the individual being requested for extradition are paramount. The Extradition Act 2003 ensures that these rights are upheld and that the process is conducted justly and transparently.

Category 1 Territories Extradition Process

As the UK exiting the European Union, it no longer participates in the European Arrest Warrant (EAW) framework post-31 December 2020. However, a new streamlined arrangement was implemented under the Trade and Cooperation Agreement (TCA) from 1 January 2021 for the Category 1 territories. Here are the general steps in the extradition process of Category 1 territories:

Warrant and Certificate Issuance

The process begins when the requesting state submits a warrant, typically electronically via Interpol. The National Crime Agency (NCA), the authority for Category 1 cases, issues a certificate after applying a proportionality test. This is in alignment with section 2 of the 2003 Act, ensuring that the requirements, such as the proportionality legal action group’s standards, are met.

Arrest & Initial Hearing

Upon issuance of the certificate, the accused or ‘requested person’ is arrested. The initial hearing led by a district judge at the magistrates’ court (for Scotland, sheriff at the sheriff’s court) promptly follows. Here, the identity of the requested person is confirmed, and they are informed about the extradition proceedings.

In urgent scenarios, a requested individual can be captured before the warrant’s receipt. However, a court hearing must occur within 48 hours of this arrest.

Extradition Hearing

Usually starting within 21 days of the arrest, the extradition hearing requires a judge to assess if the conduct described in the warrant is an “extradition offence”. Various bars to extradition, such as double jeopardy, age of the requested person, and the European Convention on Extradition’s standards, are considered.


If either party contests the judge’s decision, they may seek permission to appeal in the High Court (or the High Court of Justiciary in Scotland). Further appeals can be directed to the Supreme Court, focusing on issues of overarching legal importance or devolution concerns.

Upon ultimate court approval of the extradition, the requested person is generally expected to be deported within a period of ten days.  In some cases, it may be possible to extend the time limit beyond the usual duration if there are exceptional circumstances.

Category 2 Territories Extradition Process

The UK has established a distinct set of procedures for extradition requests with territories classified as ‘category 2’ under the Extradition Act 2003 (Part 2). Countries that have entered into formal arrangements regarding extradition, such as the Commonwealth Scheme, European Convention on Extradition, or bilateral treaties, are included within these territories.

The following are the general steps involved in the extradition process of Category 2 territories:

Extradition Request

The process starts when a ‘category 2’ territory formally communicates an extradition request to the UK, detailing the nature of the alleged crimes, evidence, and any applicable information about the individual in question. This communication is typically directed to the UK’s Secretary of State.

Warrant and Certificate Issuance

Upon receipt of the extradition plea, the UK’s Secretary of State reviews the request based on the criteria set out in the 2003 Act. When considered appropriate, the Secretary of State provides certification. If the individual in question is believed to reside in Scotland, the Scottish Ministers undertake this certification. 

Arrest & Initial Hearing

Once the court acknowledges sufficient information has been provided, an arrest warrant gets issued. Upon arrest, the concerned individual, termed the ‘requested person’, is presented in front of a court. Here, a preliminary hearing is scheduled, where the identity of the individual is confirmed, and they are introduced to the approaching extradition procedures.

Extradition Hearing

During the formal extradition hearing, a District Judge examines the details of the case to determine whether the evidence presented is sufficient for extradition. The judge also checks whether the offence is considered a crime in both countries and ensures that there are no legal barriers to extradition. Moreover, the judge evaluates the human rights implications of the case.


The judge’s decision can be challenged within 14 days of its announcement. The High Court remains the primary avenue for lodging these appeals. In cases where the District Judge decides against extradition, the requesting state can appeal this decision. Further appeals can be directed to the Supreme Court, given that the case involves matters of deep public importance.

Should the extradition be approved and not challenged, or should the challenges fail, the requested person is typically deported within 28 days following the Secretary of State’s decision to sanction the extradition. However, certain conditions, such as awaiting appeals results or other exceptional circumstances, may extend this timeline.

When time is crucial and there’s fear of someone fleeing, a provisional arrest can be requested. This allows the individual’s arrest even before the official extradition request materialises. However, once arrested provisionally, the formal extradition request must follow suit within the legally defined timeframe.

Grounds for Refusing Extradition

The UK is deeply committed to justice, human rights, and upholding the rule of law. While it seeks to cooperate internationally on criminal matters, there are particular principles it upholds that might result in the refusal of an extradition plea. Below are the primary grounds on which extradition can be refused:

Potential Risk of Torture or Inhuman/Degrading Treatment

The UK is no longer part of certain EU mechanisms post-Brexit, but it still upholds the Council of Europe’s conventions. If the requested person may face torture or any form of inhuman treatment in the requesting country, the UK can prevent extradition in alignment with the European Convention on Human Rights.

Political Offences or Motivations

If the UK believes that the extradition request is politically motivated or that the person will be prosecuted or punished for their political beliefs or affiliations, the request may be refused. This is in line with the principle that extradition should serve justice and not political vendettas.

Potential Risk of Discrimination

Extradition might be refused if there’s a reasonable belief that the requested person may suffer discrimination in the requesting state due to their race, religion, nationality, or political opinions. This consideration emphasises the UK’s commitment to human rights and non-discrimination principles.

Excessive Delay in Bringing a Case

Preparing for a contested extradition hearing involves understanding the timeline of accusations. If there’s an unjustified delay in prosecuting the accused or convicted person for the offence they’re being extradited for, it can be a legitimate ground for refusal.

The Offence is not an Extradition Offence (Dual Criminality)

An offence must be a criminal offence in both the requesting state and the UK. The concept of dual criminality ensures that a person cannot be deported for actions that aren’t deemed illegal in the UK.

Passage of Time since the Alleged Offence

If a considerable amount of time has passed since the commission of the offence and it’s deemed unjust or oppressive to extradite due to this, the request can be denied.

Potential Breach of Human Rights

The requested person’s human rights are carefully considered during extradition proceedings in the UK. If extradition poses a risk to any fundamental human rights of the individual, such as fair trial rights, it can act as a barrier.

Inadequate Prison Conditions in the Requesting Country

The UK assesses the standards of prison facilities in the requesting country. If they’re found to be below par, leading to concerns about inhuman or degrading treatment, the extradition can be halted.

The Person’s Age or Health

If the individual is of significant age or has serious health issues, making extradition inhumane or oppressive, the request can be rejected.
