Were United States v. Nixon and Zelman v. Simmons-Harris both US Supreme Court cases?
United States v. Nixon United States v. Nixon, 418 U.S. 683 (1974), was a landmark United States Supreme Court decision which resulted in a unanimous 8–0 ruling against President Richard Nixon, ordering him to deliver presidential tape recordings and other subpoenaed materials to the District Court. Issued on July 24, 1974, the ruling was important to the late stages of the Watergate scandal, when there was an ongoing impeachment process against Richard Nixon. "United States v. Nixon" is considered a crucial precedent limiting the power of any U.S. president to claim executive privilege.
Yakus v. United States Yakus v. United States, 321 U.S. 414 (1944), was a decision by the United States Supreme Court which upheld congressional power to fetter judicial review and to delegate broad and flexible law-making power to an administrative agency in this constitutional challenge to the Emergency Price Control Act of 1942. The wartime anti-inflation measure, intended to expedite price control enforcement, conferred on the federal district courts jurisdiction over violations of Office of Price Administration (OPA) regulations made under the act. But judicial power to consider the constitutionality of such regulations was accepted. Congress specified that challenges to their validity be initially reviewed under stringent time limitations by the OPA and on appeal exclusively by a special Article III tribunal in the District of Columbia—the Emergency Court of Appeals—and thereafter by the Supreme Court.
