To extradite is to surrender a person, usually a criminal suspect or convicted offender, by one state to another state so that they can be prosecuted or made to serve a sentence there. In legal practice it describes the process by which courts and governments cooperate across borders to return fugitives.In the UK, extradition is principally governed by the Extradition Act 2003, which sets out the legal tests, procedures, and safeguards for extradition from England and Wales, Scotland and Northern Ireland, including requests from EU and non‑EU states. In Ireland, extradition is mainly regulated by the Extradition Act 1965 (as amended) and EU instruments on surrender of persons.Key features include: the requirement of a valid extradition request; dual criminality (the conduct is an offence in both jurisdictions, subject to exceptions); speciality (the person may usually be tried only for the offences for which extradition was granted); and human rights protections (for example, under the ECHR and constitutional standards).Usage of “extradite” is broadly consistent across these jurisdictions, referring both to the act of surrender and to the court process leading to surrender.
