Extradition and Mutual Legal Assistance

Practice Summary

The Doughty Street Extradition Team offers unrivalled expertise in extradition law. Its members appear in the most high profile and complex extradition cases ranging from war crimes cases to multinational frauds. Members of the team have appeared in the leading extradition cases at all levels including landmark cases before the Supreme Court, House of Lords and Privy Council. The team has a unique international reach and has conducted cases before the courts of Northern Ireland, Hong Kong, Singapore, and various Caribbean jurisdictions including Trinidad and Tobago and Belize. We lead the way in litigating successful test cases on fundamental human rights and evolving areas of extradition law, setting many of the benchmark authorities on terrorism, torture, prisons, fair trial, passage of time, abuse of process and family life which are quoted daily in courts around the world.


The extradition team advises on extradition requests and mutual legal assistance before the Courts anywhere in the world, for example defending US requests before the Courts in Caribbean jurisdictions.


High-profile extradition cases of team members include Gary McKinnon v USA, Aswat v UK; Richard O’Dwyer v USA, USA v Babar Ahmad, Sweden v Julian Assange, Serbia v Ganic, USA v Christopher Tappin, Gary Mann v Portugal, Barry & Al-Fawwaz v SSHD, Symeou v. Greece, Gomes v Trinidad and Tobago, Norris v USA, HH v Italy & F-K v Poland and test cases concerning the UAE and Russia. We advise Ministries of Justice and local authorities and have appeared on behalf of governments and judicial authorities of over 30 countries. In the last 2 years we are proud to have won the only two defence extradition victories in the Supreme Court, judgments that made real changes across the extradition courts.


Our publications on extradition law, include the Extradition Law Handbook (Oxford University Press) and the Extradition Law Reports.


Interpol and Red Notice challenges


We have acted in numerous challenges to Interpol Red Notices and succeeded in securing the deletion of diffusion notices thereby defeating restrictions on travel and arrests. The team members have presented seminars and training on challenging Red Notices and have drafted expert reports for the use in English proceedings in relation to the operation of Interpol.


Two members of the team speak fluent Russian and the team as a whole is highly experienced in advising on Russia-based or related extradition or Interpol cases.


The team draws upon its unique expertise in international and human rights law to mount the strongest possible defence to extradition requests from across the world. The team boasts six acknowledged leaders in the field of extradition law (Chambers and Partners 2015), led by ‘star individual’ Edward Fitzgerald QC and Liberty Lawyer of the Year 2012, Ben Cooper.


The Doughty Street Extradition Team offers unparalleled strength in depth in this growing specialist field of international law.
