California Penal Code Section 6128

(a) The office of the Inspector General may receive communications from any individual, including those employed by any department, board, or authority who believes he or she may have information that may describe an improper governmental activity, as that term is defined in subdivision (b) of Section 8547.2 of the Government Code. It is not the purpose of these communications to redress any single disciplinary action or grievance that may routinely occur. (b) In order to properly respond to any allegation of improper governmental activity, the Inspector General shall establish a toll-free public telephone number for the purpose of identifying any alleged wrongdoing by an employee of the Department of Corrections, the Department of the Youth Authority, the Board of Prison Terms, the Board of Corrections, the Narcotic Addict Evaluation Authority, the Prison Industry Authority, or the Youth and Adult Correctional Agency. This telephone number shall be posted by the above-named departments, and their respective subdivisions, in clear view of all employees and the public. When appropriate, the Inspector General shall initiate an investigation or audit of any alleged improper governmental activity. However, any request to conduct an investigation shall be in writing. (c) All identifying information, and any personal papers or correspondence from any person who initiated the investigation shall not be disclosed, except in those cases where the Inspector General determines that disclosure of the information is necessary in the interests of justice.
