Extradition & INTERPOL Law

How UK Extradition and INTERPOL Cases Actually Work

The UK runs two distinct extradition tracks under the Extradition Act 2003, and a separate but related process for INTERPOL notices. Which one applies to you changes everything about your defense.

Direct answer: The UK operates a two-track extradition system under the Extradition Act 2003. Category 1 covers a simplified, faster process for requests from countries operating the UK’s equivalent of an EU-style arrest warrant framework. Category 2 requires a fuller judicial process, generally including evidence of a case against you. Whether you are wanted BY the UK or FROM the UK also determines which court hears your case and which defenses are available.

When Another Country Wants You, and You’re in the UK

1

Category 1 Requests

A streamlined process for requests from countries within the UK’s fast-track framework. Narrower grounds to resist, and a compressed timeline.

2

Category 2 Requests

A fuller judicial process. Depending on the requesting country’s designation, this can require the equivalent of a prima facie case to be shown.

§

Extradition Act 2003

The governing statute for any request made to the UK to surrender someone located here, as amended by subsequent legislation.

Westminster Magistrates’ Court

Where every UK extradition case opens — bail, identity, and scheduling are dealt with here, though it is rarely where the case is ultimately decided.

Grounds to Resist Extradition From the UK

UK courts will only bar extradition on specific statutory grounds. None of these apply automatically — each depends heavily on the facts of your case.

  • 01
    Human Rights (ECHR Articles 3 & 8)Extradition can be blocked where it would expose you to inhuman treatment, or disproportionately interfere with family life.
  • 02
    Passage of TimeWhere extraditing you now, given how much time has passed since the alleged offence, would be unjust or oppressive.
  • 03
    Double JeopardyWhere you have already faced trial — whether acquitted or convicted — for the same underlying conduct.
  • 04
    Forum & ProportionalityWhere it would be more appropriate, in the interests of justice, for the case to be tried in the UK instead.

When the UK Wants Someone Located Abroad

01

Request Issued

The Crown Prosecution Service and National Crime Agency issue the request, often alongside an INTERPOL notice or diffusion.

02

Heard Abroad

The case is decided in the courts of wherever the person is located, applying that country’s own extradition law and treaty obligations.

03

Local Counsel Required

A UK lawyer has no standing before a foreign court. Representation there falls to a lawyer licensed in that jurisdiction.

04

Our Role

We advise on the UK side of the matter, liaise with UK authorities, and work together with the network lawyer where the case is actually being heard.

Notices can be challenged before the Commission for the Control of INTERPOL’s Files regardless of your location. See our full CCF appeal guide →

Frequently Asked

Common Questions

What’s the difference between extradition to and from the UK?

Extradition FROM the UK means someone here is wanted elsewhere, and a UK court hears the case. Extradition TO the UK means UK authorities want someone located abroad, and a foreign court hears it instead.

Will a LawyersLink UK lawyer appear for me in court?

Yes. Representation is provided by the network lawyer admitted to practice in the relevant jurisdiction, working together with the rest of the network on strategy.

How long does a UK extradition case usually take?

Category 1 cases can resolve in weeks to a few months. Category 2 cases, particularly with appeals, can run a year or more. Timelines vary significantly by case.

Can I be extradited from the UK for something that isn’t a crime here?

Generally the alleged conduct must satisfy a dual criminality test, though the exact requirements differ between Category 1 and Category 2 requests.

Can a UK extradition decision be appealed?

Yes — appeal rights run to the High Court, on a strict and short deadline, which is why early legal advice matters so much.
