United States v. Nixon - Wikipedia

On July 24, 1974, the U.S. Supreme Court unanimously ruled President Nixon must turn over the Watergate tapes. From the article:

"The case arose out of the Watergate scandal which began during the 1972 Presidential campaign between Democratic Senator George McGovern of South Dakota and President Nixon. On June 17, 1972, about five months before the general election, five burglars broke into Democratic headquarters located in the Watergate building complex in Washington, D.C.

In May 1973, Nixon's Attorney General, Elliot Richardson, appointed Archibald Cox to the position of special prosecutor, charged with investigating the break-in.[3] In October 1973, Nixon arranged to have Cox fired in the Saturday Night Massacre. However, public outrage forced Nixon to appoint a new special prosecutor, Leon Jaworski, who was charged with conducting the Watergate investigation for the government.

In April 1974, Jaworski obtained a subpoena ordering Nixon to release certain tapes and papers related to specific meetings between the President and those indicted by the grand jury. Those tapes and the conversations they revealed were believed to contain damaging evidence involving the indicted men and perhaps the President himself.[4]

Hoping Jaworski and the public would be satisfied, Nixon turned over edited transcripts of 43 conversations, including portions of 20 conversations demanded by the subpoena. James D. St. Clair, Nixon's attorney, then requested Judge John Sirica of the U.S. District Court for the District of Columbia to quash the subpoena. While arguing before Sirica, St. Clair stated that:

"The President wants me to argue that he is as powerful a monarch as Louis XIV, only four years at a time, and is not subject to the processes of any court in the land except the court of impeachment."[5]

Sirica denied Nixon's motion and ordered the President to turn the tapes over by May 31. Both Nixon and Jaworski appealed directly to the Supreme Court which heard arguments on July 8. Nixon's attorney argued the matter should not be subject to "judicial resolution" since the matter was a dispute within the executive branch and the branch should resolve the dispute itself. Also, he claimed Special Prosecutor Jaworski had not proven the requested materials were absolutely necessary for the trial of the seven men. Besides, he claimed Nixon had an absolute executive privilege to protect communications between "high Government officials and those who advise and assist them in carrying out their duties.'"
