reg 4 Scope of the Regulations and general provisions
(1) Without prejudice to the power of the Director to allow more than the entitlements under these Regulations where he sees fit to do so, these Regulations provide for the entitlements to costs and expenses of — (a) a witness who attends court or elsewhere to give evidence at the instance of the Service, whether he gives evidence or not; and (b) any other person who, in the opinion of the appropriate officer, necessarily attends court or elsewhere for the purpose of the prosecution case otherwise than to give evidence (including an interpreter, but only if he is required because of the lack of English of a person attending to give evidence at the instance of the Service), in any proceedings conducted by the Director in the discharge of his functions under Part I of the Prosecution of Offences Act 1985; but nothing in these Regulations gives an entitlement to a person who when called refuses to give evidence. (2) Such entitlements shall be the same for a person whether his attendance on any occasion is for the purpose of one case or more than one case. (3) Where a person claims an entitlement under these Regulations it shall be for the appropriate officer to satisfy himself of the person’s entitlement before authorising the claim to be met.
