Criminal Jurisdiction Act 1975

3 (1) If a person is accused of an extra-territorial offence, and a judge of the High Court, or the court of trial, is satisfied that—

(a) he was brought to Northern Ireland pursuant to a warrant of arrest which was endorsed in the Republic of Ireland under the law of that country corresponding to the [1965 c. 45.] Backing of Warrants (Republic of Ireland) Act 1965 and which does not specify the extra-territorial offence ; and

(b) he has not, since being so brought, been at liberty for a continuous period of seven days or more ; and

(c) he is not a person as respects whom an order under paragraph 2 above has been made, or would be made if the accused so requests,

the court or judge shall, if the accused so requests, issue an order that proceedings for the trial of the extra-territorial offence shall be suspended.

(2) For the period from the date of making of the order until such time as the accused has been at liberty for a period of seven continuous days the accused shall be immune from arrest or detention, and from any other proceeding whatsoever, relating to the extraterritorial offence, or any other extra-territorial offence committed prior to his surrender (not being an offence specified in the warrant).

For the purposes of this sub-paragraph a person shall not be treated as being at liberty at any time when he is on bail.

(3) An order may be made under this paragraph at any time before entry of the plea of the accused on arraignment on the indictment for the extra-territorial offence.
