ORIGINAL.
*624 Mr. A.H. Garland for the State of Texas, in support of the demurrer. Mr. John Hancock, Mr. George Clark, Mr. C.A. Culberson and Mr. H.J. May were with him on the brief.
Mr. Edgar Allan (with whom was Mr. Attorney General on the brief) for the United States, opposing.
*630 MR. JUSTICE HARLAN delivered the opinion of the court.
This suit was brought by original bill in this court pursuant to the act of May 2, 1890, providing a temporary government for the Territory of Oklahoma. The 25th section recites the existence of a controversy between the United States and the State of Texas as to the ownership of what is designated on the map of Texas as Greer County, and provides that the act shall not be construed to apply to that county until the title to the same has been adjudicated and determined to be in the United States. In order that there might be a speedy and final judicial determination of this controversy the Attorney General of the United States was authorized and directed to commence and prosecute on behalf of the United States a *631 proper suit in equity in this court against the State of Texas, setting forth the title of the United States to the country lying between the North and South Forks of the Red River where the Indian Territory and the State of Texas adjoin, east of the one hundredth degree of longitude, and claimed by the State of Texas as within its boundary. 26 Stat. 81, 92, c. 182, § 25.
The State of Texas appeared and filed a demurrer, and, also, an answer denying the material allegations of the bill. The case is now before the court only upon the demurrer, the principal grounds of which are: That the question presented is political in its nature and character, and not susceptible of judicial determination by this court in the exercise of its jurisdiction as conferred by the Constitution and laws of the United States; that it is not competent for the general government to bring suit against a State of the Union in one of its own courts, especially when the right to be maintained is mutually asserted by the United States and the State, namely, the ownership of certain designated territory; and that the plaintiff's cause of action, being a suit to recover real property, is legal and not equitable, and, consequently, so much of the act of May 2, 1890, as authorizes and directs the prosecution of a suit in equity to determine the rights of the United States to the territory in question is unconstitutional and void.
The necessity of the present suit as a measure of peace between the General Government and the State of Texas, and the nature and importance of the questions raised by the demurrer, will appear from a statement of the principal facts disclosed by the bill and amended bill.
By a treaty between the United States and Spain, made February 22, 1819, and ratified February 19, 1821, it was provided:
"ART. 3. The boundary line between the two countries, west of the Mississippi, shall begin on the Gulph of Mexico, at the mouth of the river Sabine, in the sea, continuing north, along the western bank of that river, to the 32d degree of latitude; thence, by a line due north, to the degree of latitude where it strikes the Rio Roxo of Natchitoches or Red River; *632 then following the course of the Rio Roxo, westward, to the degree of longitude 100 west from London and 23 from Washington; then, crossing the said Red River, and running thence, by a line due north, to the river Arkansas; thence, following the course of the southern bank of the Arkansas, to its source, in latitude 42 north; and thence, by that parallel of latitude, to the South Sea. The whole being as laid down in Melish's map of the United States, published at Philadelphia, improved to the 1st of January, 1818. But, if the source of the Arkansas River shall be found to fall north or south of latitude 42, then the line shall run from the said source due south or north, as the case may be, till it meets the said parallel of latitude 42, and thence, along the said parallel, to the South Sea. All the islands in the Sabine, and the said Red and Arkansas Rivers, throughout the course thus described, to belong to the United States; but the use of the waters, and the navigation of the Sabine to the sea, and of the said rivers Roxo and Arkansas, throughout the extent of the said boundary, on their respective banks, shall be common to the respective inhabitants of both nations.
"The two high contracting parties agree to cede and renounce all their rights, claims and pretensions to the territories described by the said line; that is to say: the United States hereby cede to his Catholic Majesty, and renounce forever, all their rights, claims and pretensions, to the territories lying west and south of the above-described line; and in like manner, his Catholic Majesty cedes to the said United States, all his rights, claims and pretensions, to any territories east and north of the said line; and for himself, his heirs and successors, renounces all claim to the said territories forever." 8 Stat. 252, 254, 256, Art. 3.
For the purpose of fixing the line with precision, and of placing landmarks to designate the limits of both nations, it was stipulated that each appoint a commissioner and a surveyor, who should meet, before the end of one year from the ratification of the treaty, at Natchitoches, on the Red River, and run and mark the line "from the mouth of the Sabine to the Red River, and from the Red River to the River Arkansas, *633 and to ascertain the latitude of the source of the said river Arkansas, in conformity to what is above agreed upon and stipulated, and the line of latitude 42, to the South Sea;" making out plans and keeping journals of their proceedings, and the result to be considered as part of the treaty, having the same force as if it had been inserted therein. Art. 4, 8 Stat. 256.
At the date of the ratification of this treaty, the country now constituting Texas belonged to Mexico, part of the monarchy of Spain. Subsequently, in 1824, Mexico became a separate independent power, whereby the boundary line designated in the treaty of 1819 became the line between the United States and Mexico.
On the 12th of January, 1828, a treaty between the United States and Mexico was concluded, and subsequently, April 5, 1832, was ratified, whereby, as between those governments, the validity of the limits defined by the treaty of 1819 was confirmed. 8 Stat. 372.
By a treaty concluded April 25, 1838, between the United States and the Republic of Texas, which was ratified and proclaimed October 13, 1838, it was declared that the treaty of limits made and concluded in 1828 between the United States and Mexico "is binding upon the Republic of Texas." And in order to prevent future disputes and collisions in regard to the boundary between the two countries; as designated by the treaty of 1828, it was stipulated:
"ART. 1. Each of the contracting parties shall appoint a commissioner and surveyor, who shall meet before the termination of twelve months from the exchange of the ratifications of this convention, at New Orleans, and proceed to run and mark that portion of the said boundary which extends from the mouth of the Sabine, where that river enters the Gulf of Mexico, to the Red River. They shall make out plans and keep journals of their proceedings, and the result agreed upon by them shall be considered as part of this convention, and shall have the same force as if it were inserted therein... .
"ART. 2. And it is agreed that until this line is marked out as is provided for in the foregoing article, each of the contracting *634 parties shall continue to exercise jurisdiction in all territory over which its jurisdiction has hitherto been exercised, and that the remaining portion of the said boundary line shall be run and marked at such time hereafter as may suit the convenience of both the contracting parties, until which time each of the said parties shall exercise without the interference of the other, within the territory of which the boundary shall not have been so marked and run, jurisdiction to the same extent to which it has been heretofore usually exercised." 8 Stat. 511.
The treaty of 1838 had not been executed on the 1st day of March, 1845, when Congress, by joint resolution, consented that "the territory properly included within, and rightfully belonging to the Republic of Texas, may be erected into a new State" upon certain conditions. 5 Stat. 797. Those conditions having been accepted, Texas by a joint resolution of Congress passed December 29, 1845, was admitted into the Union on an equal footing with the original States in all respects whatever. 9 Stat. 108.
By an act of Congress, approved September 9, 1850, certain propositions were made on behalf of the United States to the State of Texas, to become obligatory upon the parties when accepted by Texas, if such acceptance was given on or before December 1, 1850. One of those propositions was that Texas would agree that its boundary on the north should commence at the point at which the meridian of one hundred degrees west from Greenwich is intersected by the parallel of thirty-six degrees thirty minutes north latitude, and run from that point due west to the meridian of one hundred and three degrees west from Greenwich, thence due south to the thirty-second degree of north latitude, thence on the parallel of thirty-two degrees of north latitude to the Rio Bravo de Norte, and thence with the channel of said river to the Gulf of Mexico; another, that Texas cede to the United States all her claim to territory exterior to the above limits and boundaries. In consideration of said establishment of boundaries, cession of claim to territory and relinquishment of claims, the United States agreed to pay to Texas the sum of ten millions *635 of dollars in a stock bearing five per cent interest, and redeemable at the end of fourteen years, the interest payable half-yearly at the Treasury of the United States. 9 Stat. 446, c. 49.
By an act of assembly approved November 25, 1850, the above propositions were accepted by Texas, and it agreed to be bound by them according to their true import.
During the whole period of nearly forty years succeeding the treaty of 1819 no action, except as above indicated, was taken to settle the boundary line in question. But, in the year 1859, a joint commission on the part of the United States and Texas commenced the work of running that line, but separated without reaching any conclusion. Nevertheless, in 1860, the commissioner upon the part of the United States completed the work, without the coöperation of the commissioner of Texas, and reported the result to the General Land Office in 1861. According to the determination of the Commissioner on the part of the United States, and under certain surveys made from 1857 to 1859, pursuant to a contract between two persons named Jones and Brown and the Commissioner of Indian Affairs, the true dividing and boundary line between the United States and the United Mexican States began where the one hundredth meridian touched the main Red River aforesaid, running thence along the line or course of what is now known as the South Fork of the Red River or river of the treaty of 1819.
After the commissioners of the United States and Texas had failed to reach an agreement, the legislature of Texas, by an act approved February 8, 1860, declared, "that all the territory contained in the following limits, to wit: Beginning at the confluence of Red River and Prairie Dog River, thence running up Red River, passing the mouth of South Fork and following main or North Red River to its intersection with the twenty-third degree of west longitude; thence due north across Salt Fork and Prairie Dog River, and thence following that river to the place of beginning; be, and the same is hereby, created into a county to be known by the name and style of the county of Greer." And by acts of its officers, *636 proceeding under its statutes, Texas assumed and exercised control and jurisdiction of the territory constituting what is called the county of Greer.
Notwithstanding those assertions of control and jurisdiction, Texas, by an act approved May 2, 1882, made provision for running and marking the line in question. That act provided for the appointment by the governor of a suitable person or persons, who, in conjunction with such person or persons as might be appointed by or on behalf of the United States for the same purpose, should run and mark the boundary line between the Territories of the United States and the State of Texas, in order that "the question may be definitely settled as to the true location of the one hundredth degree of longitude west from London, and whether the North Fork of Red River, or the Prairie Dog Fork of said river, is the true Red River designated in the treaty between the United States and Spain, made February 22, 1819."
By an act of Congress, approved January 31, 1885, provision was made for the appointment of a commission by the President to act with the commission to be appointed by the State of Texas in ascertaining and marking the point where the one hundredth meridian of longitude crosses Red River, in accordance with the terms of the treaty of 1819; the person or persons so appointed to make report of his or their action in the premises to the Secretary of the Interior, who should transmit the same to Congress at its next session after the report was made. 23 Stat. 296, c. 47.
Under the last-mentioned acts a joint commission was organized, and it assembled at Galveston, Texas, on February 23, 1886. Being unable to agree as to whether the stream now known as the North Fork of the Red River, or that now called the South Fork or Main Red River, was the river referred to in the treaty of 1819, the joint commission adjourned sine die with the understanding that each commission would make its report to the proper authorities and await instructions. The commissioners on the part of the United States reported that "the Prairie Dog Town Fork is the true boundary, and that the monument should be placed at the intersection *637 of the one hundredth meridian with this stream;" while the commission on the part of Texas reported that "the North Fork of Red River, as now named and delineated on the maps, is the Rio Roxo or Red River delineated on Melish's maps, described in the treaty of February 22, 1819, and is the boundary line of said treaty to the point where the one hundredth degree of west longitude crosses the same."
The United States claims to have jurisdiction over all the territory acquired by the treaty of 1819, containing 1,511,576.17 acres, between what has been designated as the Prairie Dog Town Fork, or Main Red River, and the North Fork of Red River, being the extreme portion of the Indian Territory lying west of the North Fork of the Red River, and east of the one hundredth meridian of west longitude from Greenwich; and that its right to said territory, so far from having been relinquished, has been continuously asserted from the ratification of the treaty of 1819 to the present time.
The bill alleges that the State of Texas, without right, claims, has taken possession of, and endeavors to extend its laws and jurisdiction over, the disputed territory, in violation of the treaty rights of the United States; that, during the year 1887, it gave public notice of its purpose to survey and place upon the market for sale, and otherwise dispose of, that territory; and that, in consequence of its proceeding to eject bona fide settlers from certain portions thereof, President Cleveland, by proclamation issued December 30, 1887, warned all persons, whether claiming to act as officers of the county of Greer, or otherwise, against selling or disposing of, or attempting to sell or dispose of, any of said lands, or from exercising or attempting to exercise any authority over them, and "against purchasing any part of said territory from any person or persons whatever." 25 Stat. 1483.
The relief asked is a decree determining the true line between the United States and the State of Texas, and whether the land constituting what is called "Greer County," is within the boundary and jurisdiction of the United States or of the State of Texas. The government prays that its rights, as asserted in the bill, be established, and that it have such other relief as the nature of the case may require.
*638 In support of the contention that the ascertainment of the boundary between a Territory of the United States and one of the States of the Union is political in its nature and character, and not susceptible of judicial determination, the defendant cites Foster v. Neilson, 2 Pet. 253, 307, 309; Cherokee Nation v. Georgia, 5 Pet. 1, 21; United States v. Arredondo, 6 Pet. 691, 711; and Garcia v. Lee, 12 Pet. 511, 517.
In Foster v. Neilson, which was an action to recover certain lands in Louisiana, the controlling question was as to whom the country between the Iberville and the Perdido rightfully belonged at the time the title of the plaintiff in that case was acquired. The United States, the court said, had perseveringly insisted that by the treaty of St. Ildefonso made October 1, 1800, Spain ceded the disputed territory as part of Louisiana to France, and that France by the treaty of Paris of 1803 ceded it to the United States. Spain insisted that the cession to France comprehended only the territory which at that time was denominated Louisiana. After examining various articles of the treaty of St. Ildefonso, Chief Justice Marshall, speaking for the court, said: "In a controversy between two nations concerning national boundary, it is scarcely possible that the courts of either should refuse to abide by the measures adopted by its own government. There being no common tribunal to decide between them, each determines for itself on its own rights, and if they cannot adjust their differences peaceably, the right remains with the strongest. The judiciary is not that department of the government to which the assertion of its interests against foreign powers is confided; and its duty commonly is to decide upon individual rights, according to those principles which the political departments of the nation have established. If the course of the nation has been a plain one, its courts would hesitate to pronounce it erroneous." Again: "After these acts of sovereign power over the territory in dispute, asserting the American construction of the treaty by which the government claims it, to maintain the opposite construction in its own courts would certainly be an anomaly in the history and practice of nations. If those departments which are entrusted with the foreign intercourse *639 of the nation, which assert and maintain its interests against foreign powers, have unequivocally asserted its rights of dominion over a country of which it is in possession, and which it claims under a treaty; if the legislature has acted on the construction thus asserted, it is not in its own courts that this construction is to be denied. A question like this respecting the boundaries of nations, is, as has been truly said, more a political than a legal question; and, in its discussion, the courts of every country must respect the pronounced will of the legislature."
In United States v. Arredondo the court, referring to Foster v. Neilson, said: "This court did not deem the settlement of boundaries a judicial but a political question  that it was not its duty to lead, but to follow the action of the other departments of the government." The same principles were recognized in Cherokee Nation v. Georgia and Garcia v. Lee.
These authorities do not control the present case. They relate to questions of boundary between independent nations, and have no application to a question of that character arising between the General Government and one of the States composing the Union, or between two States of the Union. By the Articles of Confederation, Congress was made "the last resort on appeal in all disputes and differences" then subsisting or which thereafter might arise "between two or more States concerning boundary, jurisdiction or any other cause whatever;" the authority so conferred to be exercised by a special tribunal to be organized in the mode prescribed in those Articles, and its judgment to be final and conclusive. Art. 9. At the time of the adoption of the Constitution there existed, as this court said in Rhode Island v. Massachusetts, 12 Pet. 657, 723, 724, controversies between eleven States, in respect to boundaries, which had continued from the first settlement of the colonies. The necessity for the creation of some tribunal for the settlement of these and like controversies that might arise, under the new government to be formed, must, therefore, have been perceived by the framers of the Constitution, and, consequently, among the controversies to which the judicial power of the United States was extended *640 by the Constitution, we find those between two or more States. And that a controversy between two or more States, in respect to boundary, is one to which, under the Constitution, such judicial power extends, is no longer an open question in this court. The cases of Rhode Island v. Massachusetts, 12 Pet. 657; New Jersey v. New York, 5 Pet. 284, 290; Missouri v. Iowa, 7 How. 660; Florida v. Georgia, 17 How. 478; Alabama v. Georgia, 23 How. 505; Virginia v. West Virginia, 11 Wall. 39, 55; Missouri v. Kentucky, 11 Wall. 395; Indiana v. Kentucky, 136 U.S. 479; and Nebraska v. Iowa, ante, 359, were all original suits, in this court, for the judicial determination of disputed boundary lines between States. In New Jersey v. New York, 5 Pet. 284, 290, Chief Justice Marshall said: "It has then been settled by our predecessors, on great deliberation, that this court may exercise its original jurisdiction in suits against a State, under the authority conferred by the Constitution and existing acts of Congress." And in Virginia v. West Virginia, it was said by Mr. Justice Miller to be the established doctrine of this court "that it has jurisdiction of questions of boundary between two States of this Union, and that this jurisdiction is not defeated, because in deciding that question it becomes necessary to examine into and construe compacts or agreements between those States, or because the decree which the court may render, affects the territorial limits of the political jurisdiction and sovereignty of the States which are parties to the proceeding." So, in Wisconsin v. Pelican Ins. Co., 127 U.S. 265, 287, 288; "By the Constitution, therefore, this court has original jurisdiction of suits brought by a State against citizens of another State, as well as of controversies between two States... . As to `controversies between two or more States.' The most numerous class of which this court has entertained jurisdiction is that of controversies between two States as to the boundaries of their territory, such as were determined before the Revolution by the King in Council, and under the Articles of Confederation (while there was no national judiciary) by committees or commissioners appointed by Congress."
*641 In view of these cases, it cannot, with propriety, be said that a question of boundary between a Territory of the United States and one of the States of the Union is of a political nature, and not susceptible of judicial determination by a court having jurisdiction of such a controversy. The important question therefore, is, whether this court can, under the Constitution, take cognizance of an original suit brought by the United States against a State to determine the boundary between one of the Territories and such State. Texas insists that no such jurisdiction has been conferred upon this court, and that the only mode in which the present dispute can be peaceably settled is by agreement, in some form, between the United States and that State. Of course, if no such agreement can be reached  and it seems that one is not probable  and if neither party will surrender its claim of authority and jurisdiction over the disputed territory, the result, according to the defendant's theory of the Constitution, must be that the United States, in order to effect a settlement of this vexed question of boundary, must bring its suit in one of the courts of Texas  that State consenting that its courts may be open for the assertion of claims against it by the United States  or that, in the end, there must be a trial of physical strength between the government of the Union and Texas. The first alternative is unwarranted both by the letter and spirit of the Constitution. Mr. Justice Story has well said: "It scarcely seems possible to raise a reasonable doubt as to the propriety of giving to the national courts jurisdiction of cases in which the United States are a party. It would be a perfect novelty in the history of national jurisprudence, as well as of public law, that a sovereign had no authority to sue in his own courts. Unless this power were given to the United States, the enforcement of all their rights, powers, contracts and privileges in their sovereign capacity would be at the mercy of the States. They must be enforced, if at all, in the state tribunals." Story Const. § 1674. The second alternative, above mentioned, has no place in our constitutional system, and cannot be contemplated by any patriot except with feelings of deep concern.
*642 The cases in this court show that the framers of the Constitution did provide, by that instrument, for the judicial determination of all cases in law and equity between two or more States, including those involving questions of boundary. Did they omit to provide for the judicial determination of controversies arising between the United States and one or more of the States of the Union? This question is in effect answered by United States v. North Carolina, 136 U.S. 211. That was an action of debt brought in this court by the United States against the State of North Carolina, upon certain bonds issued by that State. The State appeared, the case was determined here upon its merits, and judgment was rendered for the State. It is true that no question was made as to the jurisdiction of this court, and nothing was therefore said in the opinion upon that subject. But it did not escape the attention of the court, and the judgment would not have been rendered except upon the theory that this court has original jurisdiction of a suit by the United States against a State. As, however, the question of jurisdiction is vital in this case, and is distinctly raised, it is proper to consider it upon its merits.
The Constitution extends the judicial power of the United States "to all cases, in law and equity, arising under this Constitution, the laws of the United States and treaties made, or which shall be made, under their authority; to all cases affecting ambassadors, other public ministers and consuls; to all cases of admiralty and maritime jurisdiction; to controversies to which the United States shall be a party; to controversies between two or more States; between a State and citizens of another State; between citizens of different States; between citizens of the same State claiming lands under grants of different States, and between a State or the citizens thereof and foreign States, citizens or subjects.
"In all cases, affecting ambassadors or 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, *643 and under such regulations as the Congress shall make." Art. 3, § 2. "The judicial power of the United States shall not be construed to extend to 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." 11th Amendment.
It is apparent upon the face of these clauses that in one class of cases the jurisdiction of the courts of the Union depends "on the character of the cause, whoever may be the parties," and, in the other, on the character of the parties, whatever may be the subject of controversy. Cohens v. Virginia, 6 Wheat. 264, 378, 393. The present suit falls in each class, for it is, plainly, one arising under the Constitution, laws and treaties of the United States, and, also, one in which the United States is a party. It is, therefore, one to which, by the express words of the Constitution, the judicial power of the United States extends. That a Circuit Court of the United States has not jurisdiction, under existing statutes, of a suit by the United States against a State, is clear; for by the Revised Statutes it is declared  as was done by the Judiciary Act of 1789  that "the Supreme Court shall have exclusive jurisdiction of all controversies of a civil nature where a State is a party, except between a State and its citizens, or between a State and citizens of other States or aliens, in which latter cases it shall have original, but not exclusive, jurisdiction." Rev. Stat. § 687; Act of September 24, 1789, c. 20, § 13; 1 Stat. 80. Such exclusive jurisdiction was given to this court, because it best comported with the dignity of a State, that a case in which it was a party should be determined in the highest, rather than in a subordinate judicial tribunal of the nation. Why then may not this court take original cognizance of the present suit involving a question of boundary between a Territory of the United States and a State?
The words, in the Constitution, "in all cases ... in which a State shall be party, the Supreme Court shall have original jurisdiction," necessarily refer to all cases mentioned in the preceding clause in which a State may be made, of right, a party defendant, or in which a State may, of right, be *644 a party plaintiff. It is admitted that these words do not refer to suits brought against a State by its own citizens or by citizens of other States, or by citizens or subjects of foreign States, even where such suits arise under the Constitution, laws and treaties of the United States, because the judicial power of the United States does not extend to suits of individuals against States. Hans v. Louisiana, 134 U.S. 1, and authorities there cited; North Carolina v. Temple, 134 U.S. 22, 30. It is, however, said that the words last quoted refer only to suits in which a State is a party, and in which, also, the opposite party is another State of the Union or a foreign State. This cannot be correct, for it must be conceded that a State can bring an original suit in this court against a citizen of another State. Wisconsin v. Pelican Ins. Co., 127 U.S. 265, 287. Besides, unless a State is exempt altogether from suit by the United States, we do not perceive upon what sound rule of construction suits brought by the United States in this court  especially if they be suits the correct decision of which depends upon the Constitution, laws or treaties of the United States  are to be excluded from its original jurisdiction as defined in the Constitution. That instrument extends the judicial power of the United States "to all cases," in law and equity, arising under the Constitution, laws and treaties of the United States, and to controversies in which the United States shall be a party, and confers upon this court original jurisdiction "in all cases" "in which a State shall be party," that is, in all cases mentioned in the preceding clause in which a State may, of right, be made a party defendant, as well as in all cases in which a State may, of right, institute a suit in a court of the United States. The present case is of the former class. We cannot assume that the framers of the Constitution, while extending the judicial power of the United States to controversies between two or more States of the Union, and between a State of the Union and foreign States, intended to exempt a State altogether from suit by the General Government. They could not have overlooked the possibility that controversies, capable of judicial solution, might arise between the United States and some *645 of the States, and that the permanence of the Union might be endangered if to some tribunal was not entrusted the power to determine them according to the recognized principles of law. And to what tribunal could a trust so momentous be more appropriately committed than to that which the people of the United States, in order to form a more perfect Union, establish justice and insure domestic tranquillity, have constituted with authority to speak for all the people and all the States, upon questions before it to which the judicial power of the nation extends? It would be difficult to suggest any reason why this court should have jurisdiction to determine questions of boundary between two or more States, but not jurisdiction of controversies of like character between the United States and a State.
Mr. Justice Bradley, speaking for the court in Hans v. Louisiana, 134 U.S. 1, 15, referred to what had been said by certain statesmen at the time the Constitution was under submission to the people, and said: "The letter is appealed to now, as it was then, as a ground for sustaining a suit brought by an individual against a State... . The truth is, that the cognizance of suits and actions unknown to the law, and forbidden by the law, was not contemplated by the Constitution when establishing the judicial power of the United States. Some things, undoubtedly, were made justiciable which were not known as such at the common law; such, for example, as controversies between States as to boundary lines, and other questions admitting of judicial solution. And yet the case of Penn v. Lord Baltimore, 1 Ves. Sen. 444, shows that some of these unusual subjects of litigation were not unknown to the courts even in colonial times; and several cases of the same general character arose under the Articles of Confederation, and were brought before the tribunal provided for that purpose in those articles. 131 U.S. App. 50. The establishment of this new branch of jurisdiction seemed to be necessary from the extinguishment of diplomatic relations between the States." That case, and others in this court relating to the suability of States, proceeded upon the broad ground that "it is inherent in the nature of sovereignty not *646 to be amenable to the suit of an individual without its consent."
The question as to the suability of one government by another government rests upon wholly different grounds. Texas is not called to the bar of this court at the suit of an individual, but at the suit of the government established for the common and equal benefit of the people of all the States. The submission to judicial solution of controversies arising between these two governments, "each sovereign, with respect to the objects committed to it, and neither sovereign with respect to the objects committed to the other," McCulloch v. State of Maryland, 4 Wheat. 316, 400, 410, but both subject to the supreme law of the land, does no violence to the inherent nature of sovereignty. The States of the Union have agreed, in the Constitution, that the judicial power of the United States shall extend to all cases arising under the Constitution, laws and treaties of the United States, without regard to the character of the parties, (excluding, of course, suits against a State by its own citizens or by citizens of other States, or by citizens or subjects of foreign States,) and equally to controversies to which the United States shall be a party, without regard to the subject of such controversies, and that this court may exercise original jurisdiction in all such cases, "in which a State shall be party," without excluding those in which the United States may be the opposite party. The exercise, therefore, by this court, of such original jurisdiction in a suit brought by one State against another to determine the boundary line between them, or in a suit brought by the United States against a State to determine the boundary between a Territory of the United States and that State, so far from infringing, in either case, upon the sovereignty, is with the consent of the State sued. Such consent was given by Texas when admitted into the Union upon an equal footing in all respects with the other States.
We are of opinion that this court has jurisdiction to determine the disputed question of boundary between the United States and Texas.
It is contended that, even if this court has jurisdiction, the *647 dispute as to boundary must be determined in an action at law, and that the act of Congress requiring the institution of this suit in equity is unconstitutional and void as, in effect, declaring that legal rights shall be tried and determined as if they were equitable rights. This is not a new question in this court. It was suggested in argument, though not decided, in Fowler v. Lindsey, 3 Dall. 411, 413. Mr. Justice Washington, in that case, said: "I will not say that a State could sue at law for such an incorporeal right as that of sovereignty and jurisdiction; but even if a court of law would not afford a remedy, I can see no reason why a remedy should not be obtained in a court of equity. The State of New York might, I think, file a bill against the State of Connecticut, praying to be quieted as to the boundaries of the disputed territory; and this court, in order to effectuate justice, might appoint commissioners to ascertain and report those boundaries." But the question arose directly in Rhode Island v. Massachusetts, 12 Pet. 657, 734, which was a suit in equity in this court involving the boundary line between two States. The court said: "No court acts differently in deciding on boundary between States, than on lines between separate tracts of land; if there is uncertainty where the line is, if there is a confusion of boundaries by the nature of interlocking grants, the obliteration of marks, the intermixing of possession under different proprietors, the effects of accident, fraud or time or other kindred causes, it is a case appropriate to equity. An issue at law is directed, a commission of boundary awarded; or, if the court are satisfied without either, they decree what and where the boundary of a farm, a manor, a province or a State is and shall be." When that case was before the court at a subsequent term, Chief Justice Taney, after stating that the case was of peculiar character involving a question of boundary between two sovereign States, litigated in a court of justice, and that there were no precedents as to forms and modes of proceedings, said: "The subject was however fully considered at January term, 1838, when a motion was made by the defendant to dismiss this bill. Upon that occasion the court determined to frame their proceedings according to those which had been *648 adopted in the English courts, in cases most analogous to this, where the boundaries of great political bodies had been brought into question. And, acting upon this principle, it was then decided, that the rules and practice of the Court of Chancery should govern in conducting this suit to a final issue. The reasoning upon which that decision was founded is fully stated in the opinion then delivered; and upon reëxamining the subject, we are quite satisfied as to the correctness of this decision." 14 Pet. 210, 256. The above cases, New Jersey v. New York, Missouri v. Iowa, Florida v. Georgia, Alabama v. Georgia, Virginia v. West Virginia, Missouri v. Kentucky, Indiana v. Kentucky, and Nebraska v. Iowa, were all original suits in equity in this court, involving the boundary of States. In view of these precedents, it is scarcely necessary for the court to examine this question anew. Of course, if a suit in equity is appropriate for determining the boundary between two States, there can be no objection to the present suit as being in equity and not at law. It is not a suit simply to determine the legal title to, and the ownership of, the lands constituting Greer County. It involves the larger question of governmental authority and jurisdiction over that territory. The United States, in effect, asks the specific execution of the terms of the treaty of 1819, to the end that the disorder and public mischiefs that will ensue from a continuance of the present condition of things may be prevented. The agreement, embodied in the treaty, to fix the lines with precision, and to place landmarks to designate the limits of the two contracting nations, could not well be enforced by an action at law. The bill and amended bill make a case for the interposition of a court of equity.
Demurrer overruled.
MR. CHIEF JUSTICE FULLER, with whom concurred MR. JUSTICE LAMAR, dissenting.
MR. JUSTICE LAMAR and myself are unable to concur in the decision just announced.
This court has original jurisdiction of two classes of cases *649 only, those affecting ambassadors, other public ministers and consuls, and those in which a State shall be a party.
The judicial power extends to "controversies between two or more States;" "between a State and citizens of another State;" and "between a State or the citizens thereof, and foreign States, citizens or subjects." Our original jurisdiction, which depends solely upon the character of the parties, is confined to the cases enumerated, in which a State may be a party, and this is not one of them.
The judicial power also extends to controversies to which the United States shall be a party, but such controversies are not included in the grant of original jurisdiction. To the controversy here the United States is a party.
We are of opinion, therefore, that this case is not within the original jurisdiction of the court.
