"142. Issue of Part 3 Warrant. (1) The appropriate judge may issue a Part 3 warrant" [I interpolate that is to say a European Arrest Warrant] "in respect of a person if (a) a constable or an appropriate person applies to the judge for a Part 3 warrant, and (b) the condition in sub-section 2 or the condition in sub-section 2A is satisfied." [...] (2A) The condition is that - (a) there are reasonable grounds for believing that the person is unlawfully at large after conviction of an extradition offence by a court in the United Kingdom, and (b) either a domestic warrant has been issued in respect of the person or the person may (if unlawfully at large as mentioned in paragraph (a)) be arrested without a domestic warrant."
"(5) The statement is one that - (a) the person in respect of whom the warrant is issued [has been convicted] of an extradition offence specified in the warrant by a court in the United Kingdom, and (b) the warrant is issued with a view to his arrest and extradition to the United Kingdom for the purpose of being sentenced for the offence or of serving a sentence of imprisonment or another form of detention posed in respect of the offence."
"68A. Unlawfully at large 1) A person is alleged to be unlawfully at large after conviction of an offence if — (a)he is alleged to have been convicted of it, and. (b)his extradition is sought for the purpose of his being sentenced for the offence or of his serving a sentence of imprisonment or another form of detention imposed in respect of the offence."
"49. - Persons unlawfully at large. (1) Any person who, having been sentenced to [imprisonment or custody for life or ordered to be detained in [youth detention accommodation or in a young offenders' institution], or having been committed to a prison or remand centre, is unlawfully at large, may be arrested by a constable without warrant and taken to the place in which he is required in accordance with law to be detained."
"49(3) The provisions of the last preceding subsection shall apply to a person who is detained in custody in default of payment of any sum of money as if he were sentenced to imprisonment."
"24. We are entirely satisfied that the default term (which the court is obliged to impose as a matter of law in such circumstances as part of the process of sentencing) forms part of the original sentence, since it is an integral part of the confiscation order which, it is common ground, is unarguably part of the original sentence."
"Whether a contempt of court was an extraditable offence as a separate offence, not as in this case where confiscation forms part of the original and sentence imposed."
