Katy O'Mara

Associate Solicitor

Katy is a senior solicitor who specialises in serious and complex crime and extradition. She has managed Very High Cost Cases and works on high value, multi-handed, complex cases, often with an international dimension.

She has significant experience in defending all of the following: murder, offences of violence; rape and sexual offences; firearms offences; drug offences – possession, cultivation, importation, supply; immigration offences; all types of fraud. She has defended cases prosecuted by NCA, SFO, HMRC, DEFRA and BIS. She deals with money laundering, restraint orders, search warrants, confiscation and forfeiture cases.

Katy is a Duty Solicitor and Higher Rights Advocate and has appeared in the Court of Appeal, Crown Courts and Magistrates Courts. She also represents clients at the police station.

She is head of the Extradition Department at ITN and has had notable successes in preventing extradition to many European countries and to the USA. She has successfully resisted extradition by raising arguments about the invalidity of the warrant, dual criminality, passage of time, decisions to charge or try, retrial rights, and human rights - relying particularly on Articles 3 and 8. She regularly liaises with lawyers and experts in other jurisdictions to prepare reports for court and to work to have the warrant withdrawn and so to avoid extradition. Katy also acts as advocate for her clients at extradition hearings.

Katy completed a Masters in International Human Rights Law while living in Hong Kong and working at a human rights law firm and at a charity supporting domestic helpers.

Katy also worked for two years as an interpreter and translator in Moscow. She speaks Russian and represents many Russian-speaking and Eastern European clients.
