maintained that in order for Japanese people to fit in, their "marked physical characteristics" would have to be destroyed, that "the Negro, the Indian and the Chinaman" had already demonstrated assimilation was not possible for them. The U.S. Supreme Court heard the case, brought by Takuji Yamashita, and affirmed this race-based prohibition, citing its immediately prior issued decision in Takao Ozawa v. United States (described above). Washington's Alien Land Law would not be repealed until 1966. Pennsylvania Coal Co. v. Mahon In Pennsylvania Coal Co. v. Mahon, 260 U.S. 393 (1922), the Supreme Court held that whether a regulatory act constitutes a taking requiring compensation depends on the extent of diminution in the value of the property. The decision started the doctrine of regulatory taking. The Takings Clause originally applied only when the government physically seized or occupied property. Prior to 1922, American courts followed a clear rule: regulation of land was not a taking. Rather, it was simply an exercise of the government’s police power to protect the public health, safety, welfare, and morals. 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
