Rule 505 - Government Informer(a) Definitions.(1) "Government" means the government of the United States, of any state, or of any subdivision of any state.(2) "Informer" means any person who has furnished information to a law enforcement officer relating to or assisting in an investigation of a possible violation of law.(3) "Law enforcement officer" includes(C) members of a legislative committee or its staff conducting an investigation; and(D) members of a regulatory agency or its staff conducting an investigation.(b) General rule of privilege. The government has a privilege to refuse to disclose the identity of an informer.(c) Who May Claim the Privilege. The privilege may be claimed by counsel for the government or in the absence of counsel by another appropriate representative. The privilege may be claimed regardless of whether the information was furnished to an officer of the government claiming the privilege.(d) Exceptions: No privilege exists under paragraph (b) in the following circumstances: (1) Voluntary Disclosure. If the identity of the informer or the informer's interest inthe subject matter of the informer's communication has been disclosed to those who would have cause to resent the communication by a holder of the privilege or by the informer's own action.(2) Informer as Witness. The informer appears as a witness for the government.(e) Testimony on Merits.(1) In General. If it appears from the evidence in the case or from another showing by a party that an informer may be able to give testimony necessary to a fair determination of the issue of guilt or innocence in a criminal case or of a material issue on the merits of a civil case, whether or not the government is a party, and the government invokes a privilege, the judge may give the government an opportunity to show in camera facts relevant to determining whether the informer can, in fact, supply the testimony. The judge may make such orders regarding the procedures to be followed as are consistent with the spirit and purpose of this rule.(2) Effect of Invoking Privilege. If the judge finds there is reasonable probability that the informer can give the testimony, and the government elects not to disclose the informer's identity, the judge, on motion of the defendant in a criminal case, shall dismiss the charges to which the testimony would relate. The judge may dismiss the charges on the judge's own motion. In a civil case, the judge may make any order that justice requires.(3) Record for Appeal. Evidence submitted to the judge may 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 government.(4) Right to be Present. All counsel and parties shall be permitted to be present at every stage of the proceedings under this subparagraph, except a showing in camera at which no counsel or party shall be permitted to be present.(f) Legality of Obtained Evidence.(1) Requirements for Disclosure. The judge may require the disclosure of the identity of an informer if(A) information from the informer is relied upon to establish the legality of the means by which evidence was obtained; and(B) the party attacking the legality of obtaining the evidence makes a substantial preliminary showing that the law enforcement officer intentionally, knowingly or with reckless disregard for truth falsely swore that the information was received from an informer reasonably believed to be reliable or credible and that probable cause does not exist absent the information furnished by the informer.(2) Process of Disclosure. The judge shall, at the request of the government, direct that the disclosure be made in camera. All counsel and parties concerned with the issue of legality shall be permitted to be present at every stage of the proceeding under this subparagraph, except at a disclosure in camera, at which no counsel or parties shall be permitted to be present. If disclosure of the identity of the informer is made in camera, the record thereof 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 government.Advisory Committee Note.
