The Scope of Executive Privilege: The Nixon Case

Presidents often assert executive privilege even if the information or documents sought are not matters of national security. They argue that some degree of confidentiality is necessary for the Executive Branch to function effectively. Key advisers will hesitate to speak frankly if they must worry that what they say will eventually become a matter of public record.

The Supreme Court considered this argument in the 1974 case of United States v. Nixon. A grand jury convened by Watergate special prosecutor Leon Jaworski issued a subpoena to President Nixon requiring that he produce Oval Office tapes and various written records relevant to the criminal case against members of Nixon's Administration. Nixon resisted on grounds of executive privilege.

The Court recognized "the valid need for protection of communications between high Government officials and those who advise and assist them in the performance of their manifold duties." It noted that "[h]uman experience teaches that those who expect public dissemination of their remarks may well temper candor with a concern for appearances and for their own interests to the detriment of the decisionmaking process."

Nonetheless, the Justices concluded that the executive privilege is not absolute. Where the President asserts only a generalized need for confidentiality, the privilege must yield to the interests of the government and defendants in a criminal prosecution. Accordingly, the Court ordered President Nixon to divulge the tapes and records. Two weeks after the Court's decision, Nixon complied with the order. Four days after that, he resigned.
