...found these parts particularly interesting:

"The Court notes at the outset that there is broad language in Armstrong I stating that the PRA accords the President “virtually complete control” over his records during his time in office. 924 F.2d at 290. In particular, the court stated that the President enjoys unconstrained authority to make decisions regarding the disposal of documents: “[a]lthough the President must notify the Archivist before disposing of records ... neither the Archivist nor Congress has the authority to veto the President's disposal decision.” Id., citing H.R. Rep. No. 95–1487, at 13 (1978), reprinted in 1978 U.S.C.C.A.N. at 5744. Since the President is completely entrusted with the management and even the disposal of Presidential records during his time in office, it would be difficult for this Court to conclude that Congress intended that he would have less authority to do what he pleases with what he considers to be his personal records.

and

Section 2203(a) of the PRA directs the President, not the Archivist, to take: all such steps as may be necessary to assure that the activities, deliberations, decisions, and policies that reflect the performance of his constitutional, statutory or other official or ceremonial duties are adequately documented, and that such records are maintained as Presidential records pursuant to the requirements of this section 44 U.S.C. § 2203(a). The only reference in the entire statute to the designation of records as personal versus Presidential also calls for the decision to be made by the executive, and to be made during, and not after, the presidency. It provides: “materials produced or received by the President, [and other Executive Office employees], shall, to the extent practicable, be categorized as Presidential records or personal records upon their creation or receipt and be filed separately.” Id. § 2203(b). The PRA contains no provision obligating or even permitting the Archivist to assume control over records that the President “categorized” and “filed separately” as personal records. At the conclusion of the President's term, the Archivist only “assume[s] responsibility for ... the Presidential records.” Id. § 2203(f)(1).

"...the PRA does not confer any mandatory or even discretionary authority on the Archivist to classify records. Under the statute, this responsibility is left solely to the President. 44 U.S.C. § 2203(a)-"
