United Staes vs. Nixon
Nixon, President of the United States v. United States, No. 73-1834
Is the President's right to safeguard certain information, using his "executive privilege" confidentiality power, entirely immune from judicial review?
No. The Court held that neither the doctrine of separation of powers, nor the generalized need for confidentiality of high-level communications, without more, can sustain an absolute, unqualified, presidential privilege. The Court granted that there was a limited executive privilege in areas of military or diplomatic affairs, but gave preference to "the fundamental demands of due process of law in the fair administration of justice." Therefore, the president must obey the subpoena and produce the tapes and documents. Nixon resigned shortly after the release of the tapes.
This ruing is much on my mind lately.
