Nothing in this chapter shall limit, waive, or abrogate the scope or nature of the attorney-client privilege, whether statutory or common law, with respect to communications between attorneys employed by the Office of the Attorney General and subordinate agency personnel, or legal advice given by Office of the Attorney General attorneys to subordinate agency personnel before the date of the appointment of these attorneys to positions in the subordinate agencies. This privilege shall continue to apply fully to all communications made and legal advice provided between subordinate agency personnel and attorneys employed by the subordinate agencies after attorneys are transferred to the subordinate agency.
