Article III, Section 2, Clause 2:
In all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party, the supreme Court shall have original Jurisdiction. In all the other Cases before mentioned, the supreme Court shall have appellate Jurisdiction, both as to Law and Fact, with such Exceptions, and under such Regulations as the Congress shall make.
From the beginning, the Supreme Court has assumed that its original jurisdiction flows directly from the Constitution and is therefore self-executing without further action by Congress.1 In Chisholm v. Georgia,2 the Court entertained an action of assumpsit against Georgia by a citizen of another state. Congress in § 3 of the Judiciary Act of 17893 purported to invest the Court with original jurisdiction in suits between a state and citizens of another state, but it did not authorize actions of assumpsit in such cases nor did it prescribe forms of process for the exercise of original jurisdiction. Over the dissent of Justice Iredell, the Court, in opinions by Chief Justice Jay and Justices Blair, Wilson, and Cushing, sustained its jurisdiction and its power to provide forms of process and rules of procedure in the absence of congressional enactments. The backlash of state sovereignty sentiment resulted in the proposal and ratification of the Eleventh Amendment, which did not, however, affect the direct flow of original jurisdiction to the Court, although those cases to which states were parties were now limited to states as party plaintiffs, to two or more states disputing, or to United States suits against states.4
By 1861, Chief Justice Taney could confidently enunciate, after review of the precedents, that in all cases where original jurisdiction is given by the Constitution, the Supreme Court has authority to exercise it without further act of Congress to regulate its powers or confer jurisdiction, and that the court may regulate and mould the process it uses in such manner as in its judgment will best promote the purposes of justice.

Although Chief Justice Marshall apparently assumed the Court had exclusive jurisdiction of cases within its original jurisdiction,6 Congress from 1789 on gave the inferior federal courts concurrent jurisdiction in some classes of such cases.7 Sustained in the early years on circuit,8 this concurrent jurisdiction was finally approved by the Court itself.9 The Court has also relied on the first Congress’s interpretation of the meaning of Article III in declining original jurisdiction of an action by a state to enforce a judgment for a pecuniary penalty awarded by one of its own courts.10 Noting that § 13 of the Judiciary Act had referred to controversies of a civil nature,
Justice Gray declared that it was passed by the first Congress assembled under the Constitution, many of whose members had taken part in framing that instrument, and is contemporaneous and weighty evidence of its true meaning.
11
However, another clause of § 13 of the Judiciary Act of 1789 was not accorded the same presumption by Chief Justice Marshall, who, interpreting it to give the Court power to issue a writ of mandamus on an original proceeding, declared that, as Congress could not restrict the original jurisdiction, neither could it enlarge it, and he pronounced the clause void.12 Although the Chief Justice's interpretation of the meaning of the clause may be questioned, no one has questioned the constitutional principle it proclaimed. Although the rule deprives Congress of power to expand or contract the jurisdiction, it allows a considerable latitude of interpretation to the Court itself. In some cases, such as Missouri v. Holland,13 the Court has manifested a tendency toward a liberal construction of its original jurisdiction, but the more usual view is that our original jurisdiction should be invoked sparingly.
14 Original jurisdiction is limited and manifestly to be sparingly exercised, and should not be expanded by construction.
15 Exercise of its original jurisdiction is not obligatory on the Court but discretionary, to be determined on a case-by-case basis on grounds of practical necessity.16 It is to be honored only in appropriate cases. And the question of what is appropriate concerns of course the seriousness and dignity of the claim; yet beyond that it necessarily involves the availability of another forum where there is jurisdiction over the named parties, where the issues tendered may be litigated, and where appropriate relief may be had. We incline to a sparing use of our original jurisdiction so that our increasing duties with the appellate docket will not suffer.
17 But where claims are of sufficient seriousness and dignity,
in which resolution by the judiciary is of substantial concern, the Court will hear them.18
