Chambers UK 2020 - A Client’s Guide to the UK Legal Profession

Kingsley Napley has a wealth of experience in successfully defending extradition requests.  We are ranked in Band 1 of Chambers & Partners UK and have a superb international reputation for our work.  Having worked in this field for several decades, we have built up considerable knowledge regarding both EU (European Arrest Warrant “EAW”) and non-EU extradition cases and have an established network of international lawyers with whom we work closely.

We regularly advise clients before extradition proceedings commence. We have the skill and experience to deal with Interpol Red Notices, which are often the first indication that a person may be facing a potential extradition request.  In many cases, we are able to either negotiate with the authorities to avoid extradition proceedings completely or to obtain a more favourable outcome if a person is extradited. 

Where an extradition request is made, we advise on the technical, statutory and human rights challenges available and proactively defend our clients from these requests.  We have notable experience of successfully defending political extraditions. 

Our lawyers have provided advice in relation to many countries across the world, including most EU countries, the USA, Canada, Australia, Chile, Bolivia, New Zealand, Russia, Ukraine, Kazakhstan, Turkey, Serbia, Bosnia, Albania, Switzerland, Kenya, Egypt, Nigeria, South Africa, the UAE, India, South Korea, Japan, Sri Lanka, China and Pakistan.

A person can be liable for extradition if they are accused, or convicted of, a crime in a foreign country.  Even where a country does not have an extradition arrangement with the UK, it is possible for special arrangements to be made. 

An extradition case will have several stages.  Before extradition, preparation at an early stage is important in order to ensure that protections are in place should a request be made.   The first stage of an extradition case will involve a bail application and work must be done to ensure a full bail package can be presented to the court in case of arrest.  Following the bail application and service of the extradition request, we undertake a thorough review of the extradition request and the particular circumstances surrounding it.  Challenges to extradition include human rights considerations, such as the right to a fair trial, the right to a family life, and the right not to suffer inhuman or degrading treatment.  Other ways of defeating extradition may be based on the specific content of the extradition request itself.   The UK also provides a number of bars to extradition, which include the passage of time, double jeopardy, and the physical or mental health of a person.  We are skilled at gathering the best evidence to support any challenges to extradition and have well-established associations with a number of international experts and NGOs. 

Defending an extradition case will involve quite different considerations from a case which is prosecuted domestically.  We have the expertise to advise on the strategic considerations that are involved in any extradition case and, working in conjunction with other departments within the firm, are able provide advice across several disciplines, including Immigration, Dispute Resolution and Family. This enables us to provide a unique offering in delivering solutions to clients facing the most complex cross-border legal problems.  We are well aware of the importance of reputational considerations and frequently work with our experienced reputation and media team to protect our clients.

The team regularly lectures in relation to the extradition process under the Extradition Act 2003.  Given our unrivalled history of dealing with high profile and complex extradition cases, we also advise foreign governments in relation to extradition requests. 

We are closely involved in a number of international lawyers’ associations (including the International Bar Association, the European Criminal Bar Association and AIJA, the International Association of Young Lawyers), meaning that we have strong links to a network of international lawyers and are able to work with those lawyers to achieve favourable outcomes for clients.
