(1) Whenever the attorney general believes that any person (a) may be in possession, custody, or control of any original or copy of any book, record, report, memorandum, paper, communication, tabulation, map, chart, photograph, mechanical transcription, or other tangible document or recording, wherever situate, which he or she believes to be relevant to the subject matter of an investigation of a possible violation of RCW 19.86.020, 19.86.030, 19.86.040, 19.86.050, or 19.86.060, or federal statutes dealing with the same or similar matters that the attorney general is authorized to enforce, or (b) may have knowledge of any information which the attorney general believes relevant to the subject matter of such an investigation, he or she may, prior to the institution of a civil proceeding thereon, execute in writing and cause to be served upon such a person, a civil investigative demand requiring such person to produce such documentary material and permit inspection and copying, to answer in writing written interrogatories, to give oral testimony, or any combination of such demands pertaining to such documentary material or information: PROVIDED, That this section shall not be applicable to criminal prosecutions.

(2) Each such demand shall:

(a) State the statute and section or sections thereof, the alleged violation of which is under investigation, and the general subject matter of the investigation;

(b) If the demand is for the production of documentary material, describe the class or classes of documentary material to be produced thereunder with reasonable specificity so as fairly to indicate the material demanded;

(c) Prescribe a return date within which the documentary material is to be produced, the answers to written interrogatories are to be made, or a date, time, and place at which oral testimony is to be taken; and

(d) Identify the members of the attorney general's staff to whom such documentary material is to be made available for inspection and copying, to whom answers to written interrogatories are to be made, or who are to conduct the examination for oral testimony.

(3) No such demand shall:

(a) Contain any requirement which would be unreasonable or improper if contained in a subpoena duces tecum, a request for answers to written interrogatories, or a request for deposition upon oral examination issued by a court of this state; or

(b) Require the disclosure of any documentary material which would be privileged, or which for any other reason would not be required by a subpoena duces tecum issued by a court of this state.

(b) Delivering a duly executed copy thereof to the principal place of business in this state of the person to be served; or

(6) If, after prior court approval, a civil investigative demand specifically prohibits disclosure of the existence or content of the demand, unless otherwise ordered by a superior court for good cause shown, it shall be a misdemeanor for any person if not a bank, trust company, mutual savings bank, credit union, or savings and loan association organized under the laws of the United States or of any one of the United States to disclose to any other person the existence or content of the demand, except for disclosure to counsel for the recipient of the demand or unless otherwise required by law.

(7) No documentary material, answers to written interrogatories, or transcripts of oral testimony produced pursuant to a demand, or copies thereof, shall, unless otherwise ordered by a superior court for good cause shown, be produced for inspection or copying by, nor shall the contents thereof be disclosed to, other than an authorized employee of the attorney general, without the consent of the person who produced such material, answered written interrogatories, or gave oral testimony, except as otherwise provided in this section: PROVIDED, That:

(a) Under such reasonable terms and conditions as the attorney general shall prescribe, the copies of such documentary material, answers to written interrogatories, or transcripts of oral testimony shall be available for inspection and copying by the person who produced such material, answered written interrogatories, or gave oral testimony, or any duly authorized representative of such person;

(b) The attorney general may provide copies of such documentary material, answers to written interrogatories, or transcripts of oral testimony to an official of this state, the federal government, or other state, who is charged with the enforcement of federal or state antitrust or consumer protection laws, if before the disclosure the receiving official agrees in writing that the information may not be disclosed to anyone other than that official or the official's authorized employees. The material provided under this subsection (7)(b) is subject to the confidentiality restrictions set forth in this section and may not be introduced as evidence in a criminal prosecution; and

(c) The attorney general or any assistant attorney general may use such copies of documentary material, answers to written interrogatories, or transcripts of oral testimony as he or she determines necessary in the enforcement of this chapter, including presentation before any court: PROVIDED, That any such material, answers to written interrogatories, or transcripts of oral testimony which contain trade secrets shall not be presented except with the approval of the court in which action is pending after adequate notice to the person furnishing such material, answers to written interrogatories, or oral testimony.

(8) At any time before the return date specified in the demand, or within twenty days after the demand has been served, whichever period is shorter, a petition to extend the return date for, or to modify or set aside a demand issued pursuant to subsection (1) of this section, stating good cause, may be filed in the superior court for Thurston county, or in such other county where the parties reside. A petition, by the person on whom the demand is served, stating good cause, to require the attorney general or any person to perform any duty imposed by the provisions of this section, and all other petitions in connection with a demand, may be filed in the superior court for Thurston county, or in the county where the parties reside. The court shall have jurisdiction to impose such sanctions as are provided for in the civil rules for superior court with respect to discovery motions.

(9) Whenever any person fails to comply with any civil investigative demand for documentary material, answers to written interrogatories, or oral testimony duly served upon him or her under this section, or whenever satisfactory copying or reproduction of any such material cannot be done and such person refuses to surrender such material, the attorney general may file, in the trial court of general jurisdiction of the county in which such person resides, is found, or transacts business, and serve upon such person a petition for an order of such court for the enforcement of this section, except that if such person transacts business in more than one county such petition shall be filed in the county in which such person maintains his or her principal place of business, or in such other county as may be agreed upon by the parties to such petition. Whenever any petition is filed in the trial court of general jurisdiction of any county under this section, such court shall have jurisdiction to hear and determine the matter so presented and to enter such order or orders as may be required to carry into effect the provisions of this section, and may impose such sanctions as are provided for in the civil rules for superior court with respect to discovery motions.
