Thind's naturalization. Thind did not challenge the constitutionality of the racial restrictions. Instead, he attempted to be classified as a "free white person" within the meaning of the Naturalization Act based on the fact that Indians and Europeans share common descent from Proto-Indo-Europeans. The Supreme Court rejected Thind's argument, adding that Thind did not meet a "common sense" definition of white. The Court concluded that "the term 'Aryan' has to do with linguistic, and not with physical characteristics. Adkins v. Children's Hospital In Adkins v. Children's Hospital, 261 U.S. 525 (1923), the Supreme Court ruled that federal minimum wage legislation for women was an unconstitutional infringement of liberty of contract, as protected by the due process clause of the Fifth Amendment. Adkins was eventually overturned in the 1937 decision West Coast Hotel Co. v. Parrish. Citation style Under the Judiciary Act of 1789 the federal court structure at the time comprised District Courts, which had general trial jurisdiction; Circuit Courts, which had mixed trial and appellate (from the US District Courts) jurisdiction; and the United States Supreme Court, which had appellate jurisdiction over the federal District and Circuit courts—and for certain issues over state courts. The Supreme Court also had limited original jurisdiction (i.e., in which cases could be filed directly with the Supreme Court without first having been heard by a lower federal or state court). There were one or more federal District Courts and/or Circuit Courts in each state, territory, or other geographical region. The Judiciary Act of 1891 created the United States Courts of Appeals and reassigned the jurisdiction of most routine appeals from the district and circuit courts to these appellate courts. The Act created nine new courts that were originally known as the "United States Circuit Courts of Appeals." The new courts had jurisdiction over most appeals of lower court decisions. The Supreme Court could review either legal issues that a court of appeals certified or decisions of court of appeals by writ of certiorari. On January 1, 1912, the effective date of the Judicial Code of 1911, the old Circuit Courts were abolished, with their remaining trial court jurisdiction transferred to the U.S. District Courts.
