Section 59: Return of person to serve remainder of sentence
176.This section applies where a person who was serving a custodial sentence in the United Kingdom is extradited and then returned to this country to serve the rest of his domestic sentence (subsection (1)). In this situation the person is liable to be detained to serve the sentence and, if he is at large, he is to be regarded as being unlawfully at large (subsections (2) and (3)).
177.Time spent out of the United Kingdom in connection with the person's extradition does not count as time served towards his sentence in the United Kingdom (subsection (4)), unless he is acquitted of the extradition offence or any other offence for which he was allowed to be dealt with in the requesting territory (subsection (5)). In this situation, as set out in subsection (6), time spent in custody outside the United Kingdom, in connection with these offences, does count as time served for the purposes of the United Kingdom sentence.
