(a) When the Attorney General determines that an investigation should be made as to whether a person has engaged in, is engaging in, or shows evidence of intent to engage in any practice declared to be unlawful by this chapter, when he or she receives a request for enforcement proceedings from a consumer or labor organization, better business bureau, chamber of commerce, or any state agency, or when he or she receives a written complaint from a consumer of a practice declared to be unlawful under this chapter, he or she may:

(1) Require that person to file a statement or report in writing as to the facts and circumstances concerning the matter, together with such other data as may be reasonably related thereto;

(2) Examine under oath or take the deposition of any person in connection with the matter; and

(3) Examine any merchandise, or sample thereof, sales tickets, or other records relating thereto.

(b) Unless otherwise ordered by a court for good cause shown, no statement or documentary material produced pursuant to a demand under this section shall be produced for inspection or copying by, nor shall the contents thereof be disclosed to, any person other than the authorized employee of the Attorney General without the consent of the person who produced the material.

(c) The Attorney General or any attorney designated by him or her may use the documentary material or copies thereof in the enforcement of this chapter by presentation before any court, provided that any such material which contains trade secrets shall not be presented except with the approval of the court in which the action is pending after adequate notice to the person furnishing such material. However, when material containing trade secrets is presented with court approval, the material and the evidence pertaining thereto shall be held in camera and shall not be part of the court record or trial transcript.

(d) No statements, documents, or other information maintained or produced as a result of an ongoing investigation of possible violations of this chapter shall be disclosed to any person other than those persons specifically authorized by the Attorney General to receive such information.
