United States v. United States District Court for the Eastern District of Michigan

The government charged Plamondon and two others (defendants) with conspiracy to destroy government property and with bombing a CIA office. The defendants sought disclosure of government wiretap recordings, arguing they were needed to determine whether the government's evidence was tainted. The Attorney General admitted to warrantless wiretaps, claiming authority under the President's national security power. The district court found this violated the Fourth Amendment and ordered disclosure of the surveillance. The government sought a writ of mandamus from the Supreme Court to block the disclosure order.
