The committee may not bring a complaint against a person based upon information voluntarily given to the committee by the person in connection with a good faith request for advice under AS 24.60.158 or 24.60.160, and may not use that information against the person in a proceeding under AS 24.60.170. This section does not preclude the committee from acting on a complaint concerning the subject of a person's request for advice if the complaint is brought by another person, or if the complaint arises out of conduct taking place after the advice is requested, and does not preclude the committee from using information or evidence obtained from an independent source, even if that information or evidence was also submitted with a request for advice.
