United States v. Nixon (1974)

Following the Watergate break-in scandal (1972-1974), a subpoena was issued for tapes and papers related to meetings held by Richard Nixon in the Oval Office. The president claimed "executive privilege" to withhold the evidence, but the Supreme Court rejected his immunity claiming that no person is beyond the law. This decision reinforced the impeachment process and led to Nixon's resignation. The unanimous opinion was written by Justice Warren Burger.
