tacitly made state supreme courts the final expositors of the common law in their respective states. They were free to diverge from English precedents and from each other on the vast majority of legal issues which had never been made part of federal law by the Constitution, and the U.S. Supreme Court could do nothing, as it would ultimately concede in Erie Railroad Co. v. Tompkins (1938). By way of contrast, other English-speaking federations like Australia and Canada never adopted the Erie doctrine. That is, their highest courts have always possessed plenary power to impose a uniform nationwide common law upon all lower courts and never adopted the strong American distinction between federal and state common law. Eleventh Amendment and state sovereign immunity In Chisholm v. Georgia, , the Supreme Court ruled that Article III, Section 2 abrogated the States' sovereign immunity and authorized federal courts to hear disputes between private citizens and States. This decision was overturned by the Eleventh Amendment, which was passed by the Congress on March 4, 1794 and ratified by the states on February 7, 1795. It prohibits the federal courts from hearing "any suit in law or equity, commenced or prosecuted against one of the United States by Citizens of another State, or by Citizens or Subjects of any Foreign State". Clause 2: Original and appellate jurisdiction Clause 2 of Section 2 provides that the Supreme Court has original jurisdiction in cases affecting ambassadors, ministers and consuls, and also in those controversies which are subject to federal judicial power because at least one state is a party; the Court has held that the latter requirement is met if the United States has a controversy with a state. In other cases, the Supreme Court has only appellate jurisdiction, which may be regulated by the Congress. The Congress may not, however, amend the Court's original jurisdiction, as was found in Marbury v. Madison, (the same decision which established the principle of judicial review). Marbury held that Congress can neither expand nor restrict the original jurisdiction of the Supreme Court. However, the appellate jurisdiction of the Court is different. The Court's appellate jurisdiction is given "with such exceptions, and under such regulations as the Congress shall make." Often a court will assert a modest degree of power over a case for the threshold purpose of determining whether it has jurisdiction, and so the word "power" is not
