The motion for leave to file a bill of complaint is denied.
Justice ALITO, with whom Justice THOMAS joins, dissenting from denial of motion for leave to file complaint.
Suppose the following occurred. A Texan and a Californian are involved in a traffic accident in California. The Texan tries to sue the Californian in federal district court and invokes the "diversity" jurisdiction conferred by 28 U.S.C. § 1332(a)(1), which provides that "[t]he district courts shall have original jurisdiction of all civil actions... between ... citizens of different States" where the amount in controversy exceeds $75,000. Suppose the district court refuses to allow the filing of the complaint and explains: "I know that the Constitution and a federal statute give me jurisdiction over diversity cases, and I know that the Framers of the Constitution and the Congress that enacted the statute thought that diversity jurisdiction was important because it provides a neutral forum for out-of-state parties. But in my opinion, that's not really so important anymore, and if I have to handle diversity suits, I won't have the time I need to deal with more important matters. Therefore, in the exercise of my discretion, I am ordering that the complaint not be accepted for filing." Suppose a court of appeals affirmed this decision and the case came before us. What would we do?
We would reverse in the blink of an eye. We might also wag a finger at the lower courts and remind them that a federal court's obligation to hear and decide cases within its jurisdiction is "virtually unflagging." Colorado River Water Conservation Dist. v. United States, 424 U.S. 800, 817, 96 S.Ct. 1236, 47 L.Ed.2d 483 (1976); see also, e.g., Lexmark Int'l, Inc. v. Static Control Components, Inc., 572 U.S. 118, 126, 134 S.Ct. 1377, 188 L.Ed.2d 392 (2014); Sprint Communications, Inc. v. Jacobs, 571 U.S. 69, 77, 134 S.Ct. 584, 187 L.Ed.2d 505 (2013). We might emphasize that federal courts do not have freewheeling discretion to spurn categories of cases that they don't like.
If this is how we would respond to this imaginary Texan versus Californian tort suit, how can we refuse to allow the filing of the complaint in this case? The State of Texas wishes to sue the State of California and invokes our "original and exclusive jurisdiction of all controversies between two or more States." 28 U.S.C. § 1251(a); see also U.S. Const., Art. III, § 2, cl. 2. Can we justify our refusal to entertain Texas's suit on essentially the same ground that we would reject out of hand in the hypothetical diversity case just described, that is, on the ground that our original jurisdiction no longer seems as
In fairness to the Court, what it does in this case—claiming the discretion to refuse to entertain Texas's suit—is consistent with a practice the Court has followed for the past 45 years. But in all that time, the Court has never provided a convincing justification for the practice. In Cohens v. Virginia, 6 Wheat. 264, 5 L.Ed. 257 (1821), Chief Justice Marshall's opinion for the Court famously proclaimed: "We have no more right to decline the exercise of jurisdiction which is given, than to usurp that which is not given. The one or the other would be treason to the constitution." Id., at 404.
The Court has stepped back a bit from this categorical pronouncement—but only a bit. See, e.g., Sprint Communications, Inc., 571 U.S., at 77, 134 S.Ct. 584. The Court has repeatedly stressed that a federal court is almost always obligated to entertain a case over which it has jurisdiction. Ibid. Instances in which this is not required are the rare exception.
The Court's practice regarding original jurisdiction cases, however, has expanded far beyond anything that might be called an exception. Indeed, commentators have written that the practice has made our original jurisdiction "`almost as discretionary as [our] certiorari jurisdiction over appellate cases.'" S. Shapiro, K. Geller, T. Bishop, E. Hartnett, & D. Himmelfarb, Supreme Court Practice 639 (10th ed. 2013) (hereinafter Stern & Gressman).
How did the Court come to adopt a practice that seems so inconsistent with the principle the Cohens Court thought self-evident? Like many a questionable habit, the practice developed incrementally. For the first 150 years after the adoption of the Constitution, the Court never refused to permit the filing of a complaint in a case falling within its original jurisdiction.
Another 39 years would go by before the Court took the next step toward its current practice, and when it took that step, it did so in a roundabout way. In Massachusetts v. Missouri, 308 U.S. 1, 60 S.Ct. 39, 84 L.Ed. 3 (1939), the dispute concerned the two States' right to impose state inheritance taxes on securities held in trusts that had been created by a Massachusetts decedent but were administered in Missouri by Missouri trustees. Noting that there were ample funds in the trusts to pay the taxes imposed by both States, the Court first held the dispute was not really between two States and that therefore the controversy did not fall within the Court's exclusive original jurisdiction. Id., at 15-17, 60 S.Ct. 39. The Court then turned to Massachusetts's fallback argument that its claim could be understood as one against Missouri citizens and that therefore the claim at least fell within the Court's non-exclusive original jurisdiction over cases between a State and a citizen of another State. The Court expressed doubt that the bill could be read to assert such a claim and only then turned to the question whether the Court would be obligated to entertain the claim if the bill could be interpreted that way. The Court observed that a court is not always required to entertain a suit within its jurisdiction when the suit may be brought in another forum; that the suit at hand was not necessary for Massachusetts's "protection" because Massachusetts could apparently bring its suit in a Missouri court; and that entertaining suits like this one would potentially impose an "enormous burden" and "might seriously interfere with the discharge by th[e] Court of its duty in deciding cases and controversies appropriately brought before it." Id., at 18-19, 60 S.Ct. 39.
In Wyandotte Chemicals Corp., 401 U.S. 493, 91 S.Ct. 1005, 28 L.Ed.2d 256, the Court returned to the question of declining to exercise its non-exclusive original jurisdiction. The Court acknowledged that "it may initially have been contemplated that this Court would always exercise its original jurisdiction when properly called upon to do so." Id., at 497, 91 S.Ct. 1005. But the Court opined that changes in the American legal system had rendered that view "untenable, as a practical matter." Ibid. "What gives rise to the necessity for recognizing [the] discretion" to decline to entertain original-jurisdiction cases, the Court explained, was "pre-eminently the diminished societal concern in our function as a court of original jurisdiction and the enhanced importance of our role as the final federal appellate court." Id., at 499, 91 S.Ct. 1005.
The next year, the Court said in dicta that it would exercise the same discretion in cases within its exclusive original jurisdiction: "We construe 28 U.S.C. § 1251(a)(1), as we do Art. III, § 2, cl. 2, to honor our original jurisdiction but to make it obligatory only in appropriate cases." Illinois v. Milwaukee, 406 U.S., at 93, 92 S.Ct. 1385. The Court provided little justification for this assertion. In the next sentence, the Court noted that an important factor in determining whether a case is "appropriate" is "the availability of another forum where there is jurisdiction over the named parties," ibid., but it is hard to see how this factor has a bearing on the refusal to exercise exclusive jurisdiction. And in the final sentence devoted to the subject, the Court gave this explanation: "We incline to a sparing use of our original jurisdiction so that our increasing duties with the appellate docket will not suffer." Id., at 93-94, 92 S.Ct. 1385.
Since that time, the Court has repeatedly declined to exercise its exclusive original jurisdiction in state-versus-state cases, relying on the rationales provided in these earlier decisions. See, e.g., Wyoming v. Oklahoma, 502 U.S. 437, 112 S.Ct. 789, 117 L.Ed.2d 1 (1992); Louisiana v. Mississippi, 488 U.S. 990, 109 S.Ct. 551, 102 L.Ed.2d 579 (1988); Texas v. New Mexico, 462 U.S. 554, 103 S.Ct. 2558, 77 L.Ed.2d 1 (1983); California v. Texas, 457 U.S. 164, 102 S.Ct. 2335, 72 L.Ed.2d 755 (1982) (per curiam). Justices have written separately to question whether we really have discretion to decline to hear such cases. See Arizona, 425 U.S., at 798-799, 96 S.Ct. 1845 (Stevens, J., concurring); California v. West Virginia, 454 U.S. 1027, 102 S.Ct. 561, 70 L.Ed.2d 470 (1981) (Stevens, J., dissenting); Louisiana, 488 U.S. at 990, 109 S.Ct. 551 (White, J., dissenting); Nebraska v. Colorado, 577 U.S. 1211, 136 S.Ct. 1034, 194 L.Ed.2d 545 (2016) (THOMAS, J., joined by ALITO, J., dissenting); Arizona v. California, 589 U. S. ___, 140 S.Ct. 684, 206 L.Ed.2d 175 (2020) (same). And scholars have criticized the practice. See, e.g., R. Fallon, J. Manning, D. Meltzer, & D. Shapiro, Hart and Wechsler's The Federal Courts and the Federal System 275 (7th ed. 2015); Shapiro, Jurisdiction and Discretion, 60 N. Y. U. L. Rev. 543, 561, 576 (1985); Stevenson, 1982 B. Y. U. L. Rev., at 747-748. But the Court has not relented.
The practice of refusing to permit the filing of a complaint in cases that fall within our original jurisdiction is questionable, and that is especially true when, as in this case, our original jurisdictional is exclusive. As the history recounted above reveals, the Court adopted this practice without ever providing a convincing justification. The principal reason provided— that entertaining all suits between two States would crowd out consideration of more important matters on our appellate docket—rests on a dubious factual premise and, in any event, is essentially indistinguishable from the justification given by the imaginary district court judge with a distaste for diversity cases. And the suggestion in Louisiana v. Texas, 176 U.S., at 15, 20 S.Ct. 251, that we should hesitate to entertain suits between two States because they are of a "delicate and grave" character seems exactly backwards. It is precisely because these disputes have a "delicate and grave" character that they were placed exclusively in our hands. See The Federalist No. 81, p. 487 (C. Rossiter ed. 1961) (A. Hamilton) ("In cases in which a State might happen to be a party, it would ill suit its dignity to be turned over to an inferior tribunal"); California v. Arizona, 440 U.S. 59, 65-66, 99 S.Ct. 919, 59 L.Ed.2d 144 (1979). Unlike the regional courts of appeals, the federal district courts, and the state courts, we are not tied to any region or State and were therefore entrusted with the responsibility of adjudicating cases where the suspicion of local bias may run high. Cf. The Federalist No. 80 (A. Hamilton); Chisholm v. Georgia, 2 Dall. 419, 475, 1 L.Ed. 440 (1793). The present case is just such a suit.
This case involves a dispute between our two most populous States. In 2016, the California Legislature enacted a law, AB 1887, that prohibits state-funded or state-sponsored travel to any State whose laws fail to meet specified standards regarding discrimination on the basis of sexual orientation, gender identity, or gender expression. See Cal. Govt. Code Ann. § 11139.8 (West). The law authorizes the California attorney general to identify States that should be subject to the ban, § 11139.8(e)(1), and as of the date of the filing of Texas's motion, 11 States had been targeted: Alabama, Iowa, Kansas, Kentucky, Mississippi, North Carolina, Oklahoma, South Carolina, South Dakota, Tennessee, and Texas. According to press releases issued by California Attorney General Becerra and the State's website, 9 of the 11 States were subjected to the ban because of laws or practices designed to protect religious liberty.
In seeking to file its complaint, Texas argues that this is precisely the type of dispute for which our exclusive original jurisdiction was designed. Texas writes that "`the model case for [the] invocation of [our] original jurisdiction is a dispute between States of such seriousness that it would amount to casus belli if the States were fully sovereign.'" Brief in Support of Motion for Leave To File Bill of Complaint 15 (quoting Texas v. New Mexico, 462 U.S., at 571, n. 18, 103 S.Ct. 2558; first alteration in original). Texas notes that economic sanctions have often roiled international relations and have sometimes led to war. Brief in Support of Motion, 15-18. And Texas reminds us that the Founders were well aware of the danger of economic warfare between States. See id., at 15-16
The Republic of Texas was an independent nation for 10 years (1836-1846), and the California Republic claimed a similar status for a brief time in 1846. If they were independent nations today, it is entirely possible that their dispute would be the source of considerable international tension. As sovereign nations, they might resolve their dispute by diplomacy, by submitting it to international arbitration, or by self-help measures. When they entered the Union, these two behemoths relinquished the full measure of sovereign power that they once possessed, see Franchise Tax Bd., 587 U. S., at ___-___, 139 S.Ct., at 1497-1499, but they acquired the right to have their disputes with other States adjudicated by the Nation's highest court.
The Court now denies Texas that right. It will not even permit the filing of Texas's bill of complaint. This understanding of our exclusive original jurisdiction should be reexamined. At a minimum, we should note probable jurisdiction and receive briefing and argument on the question. Texas raises novel constitutional claims, arguing that California's travel ban violates the Privileges and Immunities Clause, U. S. Const., Art. IV, § 2, cl. 1, the Commerce Clause, Art. I, § 8, cl. 3, and the Equal Protection Clause, Amdt. 14, § 1. I express no view regarding any of those claims, but I respectfully dissent from the Court's refusal even to permit the filing of Texas's complaint.
