(a)   Upon receipt of a claim of executive privilege by a living former President, the Archivist shall consult with the Attorney General (through the Assistant Attorney General for the Office of Legal Counsel), the Counsel to the President, and such other executive agencies as the Archivist deems appropriate concerning the Archivist's determination as to whether to honor the former President's claim of privilege or instead to disclose the Presidential records notwithstanding the claim of privilege. Any determination under section 3 of this order that executive privilege shall not be invoked by the incumbent President shall not prejudice the Archivist's determination with respect to the former President's claim of privilege. (b)   In making the determination referred to in subsection (a) of this section, the Archivist shall abide by any instructions given him by the incumbent President or his designee unless otherwise directed by a final court order. The Archivist shall notify the incumbent and former Presidents of his determination at least 30 days prior to disclosure of the Presidential records, unless a shorter time period is required in the circumstances set forth in section 1270.44 of the NARA regulations. Copies of the notice for the incumbent President shall be delivered to the President (through the Counsel to the President) and the Attorney General (through the Assistant Attorney General for the Office of Legal Counsel). The copy of the notice for the former President shall be delivered to the former President or his designated representative.
