On July 24, 1974, in United States v. Nixon, the Supreme Court ruled unanimously that claims of executive privilege over the “Watergate” tapes were void. The Court ordered the President to release the tapes to the special prosecutor. On July 30, 1974, Nixon complied with the order and released the subpoenaed tapes to the public.
