§ Rule 509. Identity of informer.
Rule 509. Identity of informer.
(a) Rule of privilege. The United States or a state or subdivision thereof has a privilege to refuse to disclose the identity of a person who has furnished to a law enforcement officer information relating to or assisting in an investigation of a possible violation of a law.
(b) Who may claim. The privilege may be claimed by an appropriate representative of the public entity to which the information was furnished or the public entity bringing the prosecution.
(c) Exceptions.
(1) VOLUNTARY DISCLOSURE; INFORMER AS A WITNESS. No privilege exists under this rule if the identity of the informer or the informer's interest in the subject matter of the communication has been disclosed, by a holder of the privilege or by the informer's own action, to those who would have cause to resent the communication or if the informer appears as a witness for the prosecution.
(2) TESTIMONY ON RELEVANT ISSUE. If it appears in the case that an informer may be able to give testimony relevant to any issue in a criminal case or to a fair determination of a material issue on the merits in a civil case, and the privilege has been invoked, the court shall give the public entity an opportunity to show in camera facts relevant to determining whether the informer can, in fact, supply that testimony. The showing will ordinarily be in the form of affidavits, but the court may direct that testimony be taken if it finds that the matter cannot be resolved satisfactorily upon affidavit. If the court finds there is a reasonable probability that the informer can give the testimony, and the public entity elects not to disclose the informer's identity, in criminal cases the court on motion of the defendant, or on its own motion shall grant appropriate relief, which may include one or more of the following: requiring the prosecuting attorney to comply with an order to disclose the informer's identity, granting the defendant additional time or a continuance, relieving the defendant from making disclosures otherwise required, prohibiting the prosecuting attorney from introducing specified evidence, or dismissing charges. In fashioning appropriate relief in civil cases, the court may make any order the interests of justice require. Evidence submitted to the court shall be sealed and preserved, to be made available to the appellate court in the event of an appeal, and the contents shall not otherwise be revealed without consent of the public entity asserting the privilege. During any in camera showing, for the purpose of determining the applicability of the present privilege, no party should be present but, in its discretion, the court may allow counsel for any party and counsel for the public entity to be present.
