Arkansas v. Tennessee
Argued: Oct. 9, 1917. --- Decided: March 4, 1918
Concerning the proper location of an interstate boundary line with reference to the shores and channel of a navigable river separating one State of the Union from another, much has been written. The subject was brought under the consideration of this court in Iowa v. Illinois, 147 U.S. 1, 13 Sup. Ct. 239, 37 L. Ed. 55. In that case, Illinois contended that the boundary followed the middle of the channel of commerce, that is, the channel commonly used by steamboats and other craft navigating the river; while on the part of Iowa it was insisted that the line ran in the middle of the main body of the river, taking the middle line between its banks or shores, irrespective of where the channel of commerce might be, and that the measurements must be taken at ordinary stage of water. The contention of each State was supported by a decision of its court of last resort: Dunlieth & Dubuque Bridge Co. v. County of Dubuque, 55 Iowa, 558, 565, 8 N. W. 443; Buttenuth v. St. Louis Bridge Co., 123 Ill. 535, 548, 17 N. E. 439, 5 Am. St. Rep. 545. This court recognized these cases as presenting in the clearest terms the different views as to the line of jurisdiction between neighboring States separated by a navigable stream, and thereupon proceeded to analyze their reasoning and doctrine. From a review of the authorities upon international law, it was declared that when a navigable river constituted the boundary between two independent States the interest of each State in the navigation, and the preservation by each of its equal right in such navigation, required that the middle of the channel should mark the boundary up to which each State on its side should exercise jurisdiction; that hence, in international law, and by the usage of European nations, the term 'middle of the stream,' as applied to a navigable river, meant the middle of the channel of such stream, and that in this sense the terms were used in the treaty between Great Britain, France, and Spain, concluded at Paris in 1763, so that by the language 'a line drawn along the middle of the River Mississippi,' as there sed, the middle of the channel was indicated; that the thalweg, or middle of the navigable channel, is to be taken as the true boundary line between independent States for reasons growing out of the right of navigation, in the absence of a special convention between the States or long use equivalent thereto; and that although the reason and necessity of the rule may not be as cogent in this country, where neighboring States are under the same general government, yet the same rule must be held to obtain unless changed by statute or usage of so great a length of time as to have acquired the force of law; and that the Illinois Enabling Act of April 18, 1818 (3 Stat. 428, ch. 67, § 2), which made 'the middle of the Mississippi river' the western boundary of the State, the Missouri Enabling Act of March 6, 1820 (3 Stat. 545, ch. 22, § 2), which adopted 'the middle of the main channel of the Mississippi river' as the eastern boundary of that State, and the Wisconsin Enabling Act of August 6, 1846 (9 Stat. 56, ch. 89), which referred to 'the center of the main channel of that river,' employed these varying phrases as signifying the same thing. Hence we reached the conclusion (147 U.S. p. 13, 13 Sup. Ct. 239, 37 L. Ed. 55) that as between the different views as to the line of jurisdiction between neighboring States, separated by a navigable stream, the controlling consideration 'is that which preserves to each State equality in the right of navigation in the river.' It was accordingly adjudged and declared that the boundary line between the contesting States was 'the middle of the main navigable channel of the Mississippi river'; and a final decree to that effect was afterwards made. 202 U.S. 59, 26 Sup. Ct. 571, 50 L. Ed. 934.
The rule thus adopted, known as the rule of the 'thalweg,' has been treated as set at rest by that decision. Louisiana v. Mississippi, 202 U.S. 1, 49, 26 Sup. Ct. 408, 571, 50 L. Ed. 913; Washington v. Oregon, 211 U.S. 127, 134, 29 Sup. Ct. 47, 53 L. Ed. 118; 214 U.S. 205, 215, 29 Sup. Ct. 631, 53 L. Ed. 969. The argument submitted in behalf of the defendant State in the case at bar, including a reference to the notable recent decision of its Supreme Court in State v. Pulp Co. (1907) 119 Tenn. 47, 104 S. W. 437, has failed to convince us that this rule ought now, after the lapse of twenty-five years, to be departed from.
It is said that Arkansas has interpreted the line to be at a point equidistant from the well-defined and permanent banks of the river, that Tennessee likewise has recognized this boundary, and that by long acquiescence on the part of both States in this construction, and the exercise of jurisdiction by both in accordance therewith, the question should be treated as settled. The reference is to certain judicial decisions, and two acts of legislation. In Cessill v. State (1883) 40 Ark. 501, which was a prosecution for unlicensed sale of liquors upon a boat anchored off the Arkansas shore, it was held that the boundary line, as established by the original treaties and since observed in federal legislation, state constitutions, and judicial decisions was the 'line along the river bed equidistant from the permanent and defined banks of the ascertained channel on either side.' This was followed in subsequent decisions by the same court. Wolfe v. State (1912) 104 Ark. 140, 143, 148 S. W. 641; Kinnanne v. State (1913) 106 Ark. 286, 290, 153 S. W. 262. The first pertinent decision by the Supreme Court of Tennessee is State v. Pulp Co. (1907) 119 Tenn. 47, 104 S. W. 437, in which a similar conclusion was reached, partly upon the ground that it had been adopted by the courts of Arkansas. The legislative action referred to consists of two acts of the General Assembly of the State of Tennessee (Acts 1903, p. 1215, ch. 420; Acts 1907, p. 1723, ch. 516), each of which authorized the appointment of a commission to confer and act with a like commission representing the State of Arkansas to locate the line between the States in the old and abandoned ch nnel at the place that we now have under consideration; and the Act of 1907 further provided that if Arkansas should fail to appoint a commission, the Attorney General of Tennessee should be authorized to institute a suit against that State in this court to establish and locate the boundary line. These acts, far from treating the boundary as a line settled and acquiesced in, treat it as a matter requiring to be definitely settled, with the co-operation of representatives of the sister State if practicable, otherwise by appropriate litigation.
The Arkansas decisions had for their object the establishment of a proper rule for the administration of the criminal laws of the State, and were entirely independent of any action taken or proposed by the authorities of the State of Tennessee. They had no particular reference to that part of the river bed that was abandoned as the result of the avulsion of 1876; on the contrary, they dealt with parts of the river where the water still flowed in its ancient channel. The decision of the Supreme Court of Tennessee in State v. Pulp Co., 119 Tenn. 47, 104 S. W. 437, sustained the claim of the State to a part of the abandoned river bed which, by the rule of the thalweg, would be without that State. The combined effect of these decisions and of the legislation referred to, all of which were subsequent to the year 1876, falls far short of that long acquiescence in the practical location of a common boundary, and possession in accordance therewith, which in some of the cases has been treated as an aid in setting the question at rest. Rhode Island v. Massachusetts, 4 How. 591, 638, 639, 11 L. Ed. 1116; Indiana v. Kentucky, 136 U.S. 479, 510, 514, 518, 10 Sup. Ct. 1051, 34 L. Ed. 329; Virginia v. Tennessee, 148 U.S. 503, 522, 13 Sup. Ct. 728, 37 L. Ed. 537; Louisiana v. Mississippi, 202 U.S. 1, 53, 26 Sup. Ct. 408, 571, 50 L. Ed. 913; Maryland v. West Virginia, 217 U.S. 1, 41, 30 Sup. Ct. 268, 54 L. Ed. 645.
Therefore we find it unnecessary to decide whether the supposed agreement between the States respecting the boundary would be valid without the consent of Congress, in view of the third clause of section 10 of article 1 of the Constitution of the United States.
The next and perhaps the most important question is as to the effect of the sudden and violent change in the channel of the river that occurred in the year 1876, and which both parties properly treat as a true and typical avulsion. It is settled beyond the possibility of dispute that where running streams are the boundaries between States, the same rule applies as between private proprietors, namely, that when the bed and channel are changed by the natural and gradual processes known as erosion and accretion, the boundary follows the varying course of the stream; while if the stream from any cause, natural or artificial, suddenly leaves its old bed and forms a new one, by the process known as an avulsion, the resulting change of channel works no change of boundary, which remains in the middle of the old channel, although no water may be flowing in it, and irrespective of subsequent changes in the new channel. New Orleans v. United States, 10 Pet. 662, 717, 9 L. Ed. 573; Jefferis v. East Omaha Land Co., 134 U.S. 178, 189, 10 Sup. Ct. 518, 33 L. Ed. 872; Nebraska v. Iowa, 143 U.S. 359, 361, 367, 370, 12 Sup. Ct. 396, 36 L. Ed. 186; Missouri v. Nebraska, 196 U.S. 23, 34-36, 25 Sup. Ct. 155, 49 L. Ed. 372.
There is controversy with respect to the application of the foregoing rule to the particular circumstances of this case. It is insisted in behalf of the State of Tennessee that since the rule of the thalweg derives its origin from the equal rights of the respective States in the navigation of the river, the reason for the rule and therefore the rule itself ceases when navigation has been rendered impossible by the abandonment of a portion of the river bed as the result of an avulsion. In support of this contention we are referred to some expressions of Vattel, Almeda, M ore, and other writers; but we deem theminconclusive, and are of the opinion, on the contrary, that the contention runs counter to the settled rule and is inconsistent with the declarations of this court, in Nebraska v. Iowa, 143 U.S. 359, 367, 12 Sup. Ct. 396, 399 (36 L. Ed. 186), that 'avulsion would establish a fixed boundary, to wit: the center of the abandoned channel,' or, as it is expressed on page 370 of 143 U.S., on page 400 of 12 Sup. Ct. (36 L. Ed. 186), 'the boundary was not changed, and it remained as it was prior to the avulsion, the center line of the old channel,' and in Missouri v. Nebraska, 196 U.S. 23, 36, 25 Sup. Ct. 155, 158 (49 L. Ed. 372) that the boundary line 'must be taken to be the middle of the channel of the river as it was prior to such avulsion.'
It is contended, further, that since the avulsion of 1876 caused the old river bed to dry up, what is called 'the doctrine of the submergence and reappearance of land' must be applied, so as to establish the ancient boundary as it existed at the time of the earliest record, in this case the year 1823, with the effect of eliminating any shifting of the river bed that resulted from the erosions and accretions of the half century preceding the avulsion.
This contention is rested chiefly upon a quotation from Sir Matthew Hale, De Jure Maris, chap. 4:
'If a subject hath land adjoining the sea, and the violence of the sea swallow it up, but so that yet there be reasonable marks to continue the notice of it; or though the marks be defaced; yet if by situation and extent of quantity, and bounding upon the firm land, the same can be known, though the sea leave this land again, or it be by art or industry regained, the subject doth not lose his propriety; and accordingly it was held by Cooke and Foster, M. 7 Jac. C. B., though the inundation continue forty years.' 1 Hargraves' Law Tracts, 15; Note to Ex parte Jennings, 6 Cow. (N. Y.) 542, 16 Am. Dec. 447.
To the same effect, 2 Roll. Abr. 168, 1. 48; 6 Comyns' Dig., tit. Prerogative, D. 61, 62; 5 Bacon's Abr., tit. Prerogative, B. 1. A reference to the context shows that the portion quoted is a statement of one of several exceptions to the general rule that any increase of land per relictionem, or sudden recession of the sea, belonged of common right to the King as a part of his prerogative. It amounts to no more than saying that where the reliction did but restore that which before had been private property and had been lost through the violence of the sea, the private right should be restored if the land is capable of identification. Such a case was Mulry v. Norton, 100 N. Y. 424, 3 N. E. 581, 53 Am. Rep. 206, the true scope of which decision was pointed out in In re City of Buffalo, 206 N. Y. 319, 326, 327, 99 N. E. 850. But this doctrine has no proper bearing upon the rule we have stated with reference to boundary streams. Certainly it cannot be regarded as having the effect of carving out an exception to the rule that where the course of the stream changes through the operation of the natural and gradual processes of erosion and accretion, the boundary follows the stream; while if the stream leaves its former bed and establishes a new one as the result of an avulsion, the boundary remains in the middle of the former channel. An avulsion has this effect, whether it results in the drying up of the old channel or not. So long as that channel remains a running stream, the boundary marked by it is still subject to be changed by erosion and accretion; but when the water becomes stagnant, the effect of these processes is at an end; the boundary then becomes fixed in the middle of the channel as we have defined it, and the gradual filling up of the bed that ensues is not to be treated as an accretion to the shores but as an ultimate effect of the avulsion. The emergence of the land, however, may or may not follow, and it ought not in reason to have any controlling effect upon the location of the boundary line in the old channel. To give to it such an effect is we think, to misapply the rule quoted from Sir Matthew Hale.
How the land that emerges on either side of an interstate boundary stream shall be disposed of as between public and private ownership is a matter to be determined according to the law of each State, under the familiar doctrine that it is for the States to establish for themselves such rules of property as they deem expedient with respect to the navigable waters within their borders and the riparian lands adjacent to them. Pollard's Lessee v. Hagan, 3 How. 212, 230, 11 L. Ed. 565; Barney v. Keokuk, 94 U.S. 324, 338, 24 L. Ed. 224; Hardin v. Jordan, 140 U.S. 371, 382, 11 Sup. Ct. 808, 838, 35 L. Ed. 428; Shively v. Bowlby, 152 U.S. 1, 40, 58, 14 Sup. Ct. 548, 38 L. Ed. 331; St. Anthony Water Falls Power Co. v. Water Com'rs, 168 U.S. 349, 358, 18 Sup. Ct. 157, 42 L. Ed. 497; Scott v. Lattig, 227 U.S. 229, 242, 33 Sup. Ct. 242, 57 L. Ed. 490, 44 L. R. A. (N. S.) 107. Thus Arkansas may limit riparian ownership by the ordinary high-water mark (Railway v. Ramsey, 53 Ark. 314, 323, 13 S. W. 931, 8 L. R. A. 559, 22 Am. St. Rep. 195; Wallace v. Driver, 61 Ark. 429, 435, 436, 33 S. W. 641, 31 L. R. A. 317); and Tennessee, while extending riparian ownership upon navigable streams to ordinary low-water mark, and reserving as public the lands constituting the bed below that mark (Elder v. Burrus, 25 Tenn. [6 Humph.] 358, 368; Martin v. Nance, 40 Tenn. [3 Head] 649, 650; Goodwin v. Thompson, 83 Tenn. [15 Lea] 209, 54 Am. Rep. 410), may, in the case of an avulsion followed by a drying up of the old channel of the river, recognize the right of former riparian owners to be restored to that which they have lost through gradual erosions in times preceding the avulsion, as she has done in State v. Pulp Co., 119 Tenn. 47, 104 S. W. 437. But these dispositions are in each case limited by the interstate boundary, and cannot be permitted to press back the boundary line from where otherwise it should be located.
It is hardly necessary to say that State v. Pulp Co., supra, and Stockley v. Cissna, 119 Fed. 812, 56 C. C. A. 324, relied upon in defendant's answer as judicial determinations of the boundary line, can have no such effect against the State of Arkansas, which was a stranger to the record in both cases.
Upon the whole case we conclude that the questions submitted for our determination are to be answered as follows: (1) The true boundary line between the States, aside from the question of the avulsion of 1876, is the middle of the main channel of navigation as it existed at the Treaty of Peace concluded between the United States and Great Britain in 1783, subject to such changes as have occurred since that time through natural and gradual processes.
(2) By the avulsion of 1876 the boundary line between the States was unaffected, and remained in the middle of the former main channel of navigation, as above defined.
(3) The boundary line should now be located according to the middle of that channel as it was at the time the current ceased to flow therein as a result of the avulsion of 1876.
(4) A commission consisting of three competent persons, to be named by the court upon the suggestion of counsel, will be appointed to run, locate, and designate the boundary line between the States at the place in question in accordance with the above principles.
(5) The nature and extent of the erosions and accretions that occurred in the old channel prior to its abandonment by the current as a result of the avulsion of 1876, and the question whether it is practicable now to locate accurately the line of the river as it then ran, will be referred to said commission, subject to a review of its decision by this court if need be.
The parties may submit the form of an interlocutory decree to carry into effect the above conclusions.
