California Evidence Code
(a) As used in this section, "official information" means information acquired in confidence by a public employee in the course of his or her duty and not open, or officially disclosed, to the public prior to the time the claim of privilege is made.
(b) A public entity has a privilege to refuse to disclose official information, and to prevent another from disclosing official information, if the privilege is claimed by a person authorized by the public entity to do so and:
(1) Disclosure is forbidden by an act of the Congress of the United States or a statute of this state; or
(2) Disclosure of the information is against the public interest because there is a necessity for preserving the confidentiality of the information that outweighs the necessity for disclosure in the interest of justice; but no privilege may be claimed under this paragraph if any person authorized to do so has consented that the information be disclosed in the proceeding. In determining whether disclosure of the information is against the public interest, the interest of the public entity as a party in the outcome of the proceeding may not be considered.
(c) Notwithstanding any other provision of law, the Employment Development Department shall disclose to law enforcement agencies, in accordance with the provisions of subdivision (k) of Section 1095 and subdivision (b) of Section 2714 of the Unemployment Insurance Code, information in its possession relating to any person if an arrest warrant has been issued for the person for commission of a felony.
(a) Except as provided in this section, a public entity has a privilege to refuse to disclose the identity of a person who has furnished information as provided in subdivision (b) purporting to disclose a violation of a law of the United States or of this state or of a public entity in this state, and to prevent another from disclosing such identity, if the privilege is claimed by a person authorized by the public entity to do so and:
(1) Disclosure is forbidden by an act of the Congress of the United States or a statute of this state; or
(2) Disclosure of the identity of the informer is against the public interest because there is a necessity for preserving the confidentiality of his identity that outweighs the necessity for disclosure in the interest of justice; but no privilege may be claimed under this paragraph if any person authorized to do so has consented that the identity of the informer be disclosed in the proceeding. In determining whether disclosure of the identity of the informer is against the public interest, the interest of the public entity as a party in the outcome of the proceeding may not be considered.
(b) This section applies only if the information is furnished in confidence by the informer to:
(1) A law enforcement officer;
(2) A representative of an administrative agency charged with the administration or enforcement of the law alleged to be violated; or
(3) Any person for the purpose of transmittal to a person listed in paragraph (1) or (2).
(c) There is no privilege under this section to prevent the informer from disclosing his identity.
(a) Except where disclosure is forbidden by an act of the Congress of the United States, if a claim of privilege under this article by the state or a public entity in this state is sustained in a criminal proceeding, the presiding officer shall make such order or finding of fact adverse to the public entity bringing the proceeding as is required by law upon any issue in the proceeding to which the privileged information is material.
(b) Notwithstanding subdivision (a), where a search is made pursuant to a warrant valid on its face, the public entity bringing a criminal proceeding is not required to reveal to the defendant official information or the identity of an informer in order to establish the legality of the search or the admissibility of any evidence obtained as a result of it.
(c) Notwithstanding subdivision (a), in any preliminary hearing, criminal trial, or other criminal proceeding, any otherwise admissible evidence of information communicated to a peace officer by a confidential informant, who is not a material witness to the guilt or innocence of the accused of the offense charged, is admissible on the issue of reasonable cause to make an arrest or search without requiring that the name or identity of the informant be disclosed if the judge or magistrate is satisfied, based upon evidence produced in open court, out of the presence of the jury, that such information was received from a reliable informant and in his discretion does not require such disclosure.
(d) When, in any such criminal proceeding, a party demands disclosure of the identity of the informant on the ground the informant is a material witness on the issue of guilt, the court shall conduct a hearing at which all parties may present evidence on the issue of disclosure. Such hearing shall be conducted outside the presence of the jury, if any. During the hearing, if the privilege provided for in Section 1041 is claimed by a person authorized to do so or if a person who is authorized to claim such privilege refuses to answer any question on the ground that the answer would tend to disclose the identity of the informant, the prosecuting attorney may request that the court hold an in camera hearing. If such a request is made, the court shall hold such a hearing outside the presence of the defendant and his counsel. At the in camera hearing, the prosecution may offer evidence which would tend to disclose or which discloses the identity of the informant to aid the court in its determination whether there is a reasonable possibility that nondisclosure might deprive the defendant of a fair trial. A reporter shall be present at the in camera hearing. Any transcription of the proceedings at the in camera hearing, as well as any physical evidence presented at the hearing, shall be ordered sealed by the court, and only a court may have access to its contents. The court shall not order disclosure, nor strike the testimony of the witness who invokes the privilege, nor dismiss the criminal proceeding, if the party offering the witness refuses to disclose the identity of the informant, unless, based upon the evidence presented at the hearing held in the presence of the defendant and his counsel and the evidence presented at the in camera hearing, the court concludes that there is a reasonable possibility that nondisclosure might deprive the defendant of a fair trial.
(a) In any case in which discovery or disclosure is sought of peace or custodial officer personnel records or records maintained pursuant to Section 832.5 of the Penal Code or information from those records, the party seeking the discovery or disclosure shall file a written motion with the appropriate court or administrative body upon written notice to the governmental agency which has custody and control of the records. The written notice shall be given at the times prescribed by subdivision (b) of Section 1005 of the Code of Civil Procedure. Upon receipt of the notice the governmental agency served shall immediately notify the individual whose records are sought.
(b) The motion shall include all of the following:
(1) Identification of the proceeding in which discovery or disclosure is sought, the party seeking discovery or disclosure, the peace or custodial officer whose records are sought, the governmental agency which has custody and control of the records, and the time and place at which the motion for discovery or disclosure shall be heard.
(2) A description of the type of records or information sought.
(3) Affidavits showing good cause for the discovery or disclosure sought, setting forth the materiality thereof to the subject matter involved in the pending litigation and stating upon reasonable belief that the governmental agency identified has the records or information from the records.
(c) No hearing upon a motion for discovery or disclosure shall be held without full compliance with the notice provisions of this section except upon a showing by the moving party of good cause for noncompliance, or upon a waiver of the hearing by the governmental agency identified as having the records.
Nothing in this article shall be construed to affect the right of access to records of medical or psychological history where such access would otherwise be available under Section 996 or 1016.
(a) Nothing in this article shall be construed to affect the right of access to records of complaints, or investigations of complaints, or discipline imposed as a result of those investigations, concerning an event or transaction in which the peace officer or custodial officer, as defined in Section 831.5 of the Penal Code, participated, or which he or she perceived, and pertaining to the manner in which he or she performed his or her duties, provided that information is relevant to the subject matter involved in the pending litigation.
(b) In determining relevance, the court shall examine the information in chambers in conformity with Section 915, and shall exclude from disclosure:
(1) Information consisting of complaints concerning conduct occurring more than five years before the event or transaction that is the subject of the litigation in aid of which discovery or disclosure is sought.
(2) In any criminal proceeding the conclusions of any officer investigating a complaint filed pursuant to Section 832.5 of the Penal Code.
(3) Facts sought to be disclosed that are so remote as to make disclosure of little or no practical benefit.
(c) In determining relevance where the issue in litigation concerns the policies or pattern of conduct of the employing agency, the court shall consider whether the information sought may be obtained from other records maintained by the employing agency in the regular course of agency business which would not necessitate the disclosure of individual personnel records.
(d) Upon motion seasonably made by the governmental agency which has custody or control of the records to be examined or by the officer whose records are sought, and upon good cause showing the necessity thereof, the court may make any order which justice requires to protect the officer or agency from unnecessary annoyance, embarrassment or oppression.
(e) The court shall, in any case or proceeding permitting the disclosure or discovery of any peace or custodial officer records requested pursuant to Section 1043, order that the records disclosed or discovered may not be used for any purpose other than a court proceeding pursuant to applicable law.
In any case, otherwise authorized by law, in which the party seeking disclosure is alleging excessive force by a peace officer or custodial officer, as defined in Section 831.5 of the Penal Code, in connection with the arrest of that party, or for conduct alleged to have occurred within a jail facility, the motion shall include a copy of the police report setting forth the circumstances under which the party was stopped and arrested, or a copy of the crime report setting forth the circumstances under which the conduct is alleged to have occurred within a jail facility.
Records of peace officers or custodial officers, as defined in Section 831.5 of the Penal Code, including supervisorial officers, who either were not present during the arrest or had no contact with the party seeking disclosure from the time of the arrest until the time of booking, or who were not present at the time the conduct is alleged to have occurred within a jail facility, shall not be subject to disclosure.
