(a) On motion promptly made by a person who receives such a demand from the Attorney General, the judge who authorized the issuance of the investigative demand, if available, and if not, another member of the judge's court, upon notice and good cause shown, may make any order which is deemed appropriate and just to protect the person from an improper demand from the Attorney General.
(b) If the Attorney General determines that it would not be in the best interests of the investigation to disclose the evidence on which the Attorney General relied to establish the belief that unlawful conduct has occurred, is occurring or is about to occur, the Attorney General may request, and the court may examine, in camera, the evidence upon which the Attorney General relied in order to rule on such a motion.
