The Attorney General may, with the approval of the Treasury, by regulations make such provision as he considers appropriate in relation to—
the fees of any legal representative briefed to appear on behalf of the Service in any criminal proceedings or extradition proceedings ; and
the costs and expenses of witnesses attending to give evidence at the instance of the Service and, subject to subsection (1A) below, of any other person who in the opinion of the Service necessarily attends for the purpose of the case otherwise than to give evidence.
The power conferred on the Attorney General by subsection (1)(b) above only relates to the costs and expenses of an interpreter if the interpreter is required because of the lack of English of a person attending to give evidence at the instance of the Service.
In subsection (1)(b) above "attending " means attending at the court or elsewhere.
The regulations may, in particular—
prescribe scales or rates of fees, costs or expenses; and
specify conditions for the payment of fees, costs or expenses.
Regulations made under subsection (1)(b) above may provide that scales or rates of costs and expenses shall be determined by the Attorney General with the consent of the Treasury.
