(B) A member of a legislative committee or its staff conducting an investigation.
(b) Who may claim the privilege. An authorized representative of the public entity that received the information may claim the privilege.

(d) Testimony on relevant issue. If it appears that an informant may be able to give relevant testimony in a civil or criminal case to which a public entity is invokes the privilege:
(1) The court may give the public entity an opportunity to show, in camera and on the record, whether the informant can, in fact, supply the relevant testimony. The showing may be in the form of affidavits or, if the court finds that the matter cannot be satisfactorily resolved with affidavits, through testimony.
(2) If the court finds that there is a reasonable probability that the informer can give relevant testimony, the court may, either on its own or on motion of a party, enter an order requiring the public entity to disclose the identity of the informant within a specific time and providing relief to other parties in the event the public entity elects not to disclose the identity of the informant within the time specified.

(C) When ordering relief, the court shall ensure that:
(i) Evidence submitted to the court must be sealed and preserved for appeal;
(ii) A docket entry specifying the form, but not the content, of the evidence must be made; and
(iii) All counsel and parties may be present at every stage of the proceedings under this rule, except that, at a showing in camera, only counsel for the public entity may be present.
