Check the ruling from the Clinton sock drawer case, then get back to me.
I already read that decision, and it doesn’t say what you think it does. Essentially, the case involved Judicial Watch trying to force NARA to recover the tapes from Clinton after they refused to do so. The court held that the statute did not allow the court to do that, and so the case was dismissed. In the opinion, the court did note that while NARA did not make the decision to classify the tapes as personal, NARA did say that if forced to make that determination, they would have agreed with Clinton. The case did NOT say anything the President takes with him as he leaves office becomes his personal property. It does not even say that the decision by the president to classify something as personal cannot be judicially reviewed. It just says the court cannot force NARA to pursue that course of action if it chooses not to.
