which the state legislatures of three-fourths of the states or, if prescribed by Congress state ratifying conventions in three-fourths of the states, must act upon the proposed amendment, then the proposed amendment remains pending business before the state legislatures (or ratifying conventions). The case centered on the Child Labor Amendment, which was proposed for ratification by Congress in 1924. In light of the precedent established by this ruling, three proposed constitutional amendments, in addition to the Child Labor Amendment, are considered still to be pending before the state legislatures, since Congress did not specify a ratification deadline: the Congressional Apportionment Amendment since 1789; the Titles of Nobility Amendment since 1810; and the Corwin Amendment since 1861. Federal court system 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.
