The nominated court has the like powers for securing the attendance of the witness to give evidence through the link as it has for the purpose of proceedings before the court.

In Scotland the nominated court has power to issue a warrant to officers of law to cite the witness for the purpose of securing his attendance to give evidence through the link, and section 156 of the Criminal Procedure (Scotland) Act 1995 (c. 46) applies in relation to the witness if so cited.
