This is an action to recover the difference between the statutory rate upon certain coal shipments and an alleged reasonable rate. It arose upon the following facts:
In the year 1907, the legislature of North Dakota passed a statute *74prescribing a schedule of maximum rates to be charged for hauling lignite coal. When the law went into effect the carriers declined to comply with it, whereupon an action was brought to enjoin the continued violation. In this action, the carriers Avere unsuccessful. State ex rel. McCue v. Northern P. R. Co. 19 N. D. 45, 25 L.R.A.(N.S.) 1001, 120 N. W. 869, and Northern P. R. Co. v. North Dakota, 216 U. S. 579, 54 L. ed. 624, 30 Sup. Ct. Rep. 423. A supersedeas having been obtained, the statutory rate Avas not put into operation until after the decree of the United States Supreme Court, in March, 1910. The ease was later reopened in accordance with the terms of tho decree and additional evidence taken. It was then determined by this court that the statutory rates were reasonable, but it was ultimately held by the United States Supreme Court that the rates were confiscatory. State ex. rel. McCue v. Northern P. R. Co. 26 N. D. 438, 145 N. W. 135; Northern P. R. Co. v. North Dakota, 236 U. S. 585, 59 L. ed. 735, L.R.A.1917F, 1148, P.U.R.1915C, 277, 35 Sup. Ct. Rep. 429, Ann. Cas. 1916A, 1. The portion of the complaint AAdiieh states tho alleged cause of action is as follows: “That the plaintiff at the time said shipments moved, and until the 11th day of June, 1915, by reason of the mándate of the Supreme Court of the United States and the decree entered in the supreme court of the state in the year 1910, aforesaid, Avithout its consent and against its will, Avas coerced and forced to accept and transport for the defendant all of said shipments upon payment to the plaintiff of the rates and charges prescribed in said chapter 51. That from and after the 11th day of June, 1915, when final judgment was entered in the supreme court of the state in said state case as aforesaid, plaintiff became entitled to recover from the defendant the difference between said lawful and reasonable rates and the rates prescribed by said chapter 51 heretofore paid by the defendant, amounting in all to the sum of $26,819.99.”
It will be noted that the complaint alleges that, by reason of the decree of the United States Supreme Court, the plaintiff Avas coerced and forced to accept and transport shipments for the defendant at rates prescribed by chapter 51 of the Session Laws of North Dakota for the year 1907. The remainder of the paragraph merely states a legal conclusion to the effect that, by reason of said shipments, the plaintiff became entitled to recover from the defendant the difference between *75a reasonable rate and the rate prescribed by the statute, which right is alleged to have arisen on June 11, 1915. It will be observed that it is not alleged that the defendant performed the services under protest or under any sort of legal compulsion, except such as was imposed by the mandate of the Supreme Court of the United States. The decree referred to affirmed that of this court, granting an injunction to prevent the violation of the statute, and the opinion of the court concludes as follows (Northern P. R. Co. v. North Dakota, 216 U. S. 579—581, 54 L. ed. 624, 625, 30 Sup. Ct. Rep. 423) : “We do not say that experiment may not establish a case in the future that would require a decision upon the question of constitutional law, but we can express no opinion upon it now. The great difficulty in the attempt to measure the reasonableness of charges by reference to the cost of transporting the particular class of freight concerned is well known and often has been remarked. It seems to us that the nearest approach to justice that can be made at this time is to follow the precedent of Willcox v. Consolidated Gas Co. 212 U. S. 19, 53 L. ed. 382, 48 L.R.A.(N.S.) 1134, 29 Sup. Ct. Rep. 192, 15 Ann. Cas. 1034, as nearly as may be, and affirm the decree, but without prejudice to the right of the railroad company to reopen the ease by appropriate proceedings, if, after adequate trial, it thinks it can prove more clearly than at present the confiscatory character of the rates for coal.” Following the entry of the above decree, the statutory rate was put into effect in conformity with the judgment.
The pertinent inquiry is: what is the basis for the legal conclusion that, by reason of the shipments, the plaintiff became entitled to recover from the defendant? It is elementary that a pleading which states legal conclusions merely does not state a cause of action; it must state facts from which the legal conclusion of liability follows. It is equally elementary that the facts stated must bring the plaintiff within the operation of some rule of substantive law, according to which a liability may be found to exist. Obviously, the relations between a carrier and a shipper are governed by the same basic principles that would control were they between individuals and related to matters not commonly subject to the regulatory power of the state. A departure from these principles in the case of earners is only to be countenanced when their application threatens to embarrass, or does actually *76interfere with, the exercise of the regulatory power of the government in the interest of justice and equality. Thus, the liberty to contract for the services of a carrier is generally interfered with to the extent necessary to prevent discrimination as between patrons. But we are aware of no rule or policy that requires a determination of this case upon any principle peculiar to the relations of public carriers. It being clear that the liability contended for is not a tort liability, before a recovery can be had it must be found that the defendant is indebted to the plaintiff under an obligation in the nature of contract. This brings us to a consideration of the circumstances alleged in the complaint, and those reasonably inferable from the facts there alleged, for the purpose of determining, first, whether there was any contract, express or implied in fact, for the payment of the difference sought to be recovered; and second, whether, in case no contract in fact is alleged, the complaint states facts from which it must be held that there was a legal obligation in the nature of a contract obligation which could be enforced in this action.
If it be assumed that the shipper acted at all times with full knowledge of the litigation and of its ultimate result, could it then be further assumed that he agreed in fact to pay for the services at a higher rate than that fixed by statute if, perchance, the decree should be modified or reversed at some subsequent time? We think not. A business man acting with full knowledge of the facts that the law in question had been attacked, and that those interested in stopping its action had been defeated after prolonged litigation carried to the highest court in the land, would, we believe, be more' apt to assume that he was justified in dealing with the carrier on the hypothesis of the validity of the law, and in the absence of express protest, that the services of the carrier were rendered voluntarily. By “voluntarily” in this connection is meant in voluntary obedience to a supposed law. Sections 4339-4342 of the Bevised Codes of 1905 (Comp. Laws 1913, §§ 4724 — 4727) require, among other things, that the carriers shall print and keep for public inspection schedules showing the rates which are in force at the given time, and they are required to file such schedules with the Bail-road Commission. Manifestly, if shippers cannot rely upon the rates as so published and filed, the requirement of publication becomes a mere trap for the unwary. In our judgment, it is wholly improper, *77In the absence of clear allegations of the rendition of services under a distinct protest, for a court to find that a shipper had, in effect, undertaken conditionally to pay according to a rate different from that published in compliance with the statute. The foregoing considerations lead inevitably to the conclusion that there was no contract in fact, either express or implied, to pay any rate other than the statutory rate, and that which, from the entry of the decree forward, must be presumed to have been filed and published in accordance with the provisions of § 4727, Comp, laws 1913, Revised Codes of 1905, § 4342. This should dispose of the complaint, in so far as it may bo thought to state a cause of action upon a contract either express or implied in fact.
But it is urged ‘that the obligation to pay a reasonable rate arose as a matter of law, regardless of any express contract or any contract which might have been implied in fact. But this contention is without merit, for the reason that the elements essential to the implication of a contract in law are likewise lacking. Where there is no contract in fact, either implied or express, the law will not imply one except to support a recovery in favor of a plaintiff on the principle that the defendant has been unjustly enriched at his expense. While authorities In point are singularly lacking, the controlling principle is clearly the same as in case of mistake, and it is elementary that where the defendant is free from responsibility for plaintiff’s mistake, or is responsible in no greater degree than the plaintiff, and where his position is such that the enforcement of restitution would subject him to loss, the defendant is entitled to retain whatever benefit he has derived from the mistake. Woodward, Quasi Contr. § 20. In such cases it may be unfortunate that the law does not attempt to distribute the loss; but, until some other basis, for recovery than that of unjust enrichment is established, the party who has sustained the loss must bear it. To allow the plaintiff, to recover in this action is to visit the consequences of the wrong imposed, without the fault of either, upon one who would be incapable of obtaining reparation from those who are probably the real beneficiaries of the wrong (the consumer of the commodity).
It frequently happens that the risk of certain contingencies affecting a transaction must, as a matter of law, be held to be borne by one party rather than the other. The law always leaves a loss where it *78finds it, unless there is something to indicate that there was an intention to the contrary, or unless it distinctly fixes the burden otherwise. The situation of the plaintiff in the case at bar is very much the same as that described by Justice Learned in the case of Windbiel v. Carroll, 16 Hun, 101, wherein he stated (page 103): “Ignorance of the fact is one thing; ignorance of the means of proving the fact is another. When money voluntarily paid is recovered back [and this would be no-less true as to services rendered], it - is because there was a mistake as to some fact. But here the plaintiff was not mistaken as to the fact. Only at the time he did not know how to prove it. The subsequent discovery of evidence to prove the fact, known to the party when he makes the payment, cannot authorize a recovery back of the money. Such a principle would be most dangerous.”
In the case at bar, the plaintiff, from the beginning of the proceedings involving the rate, professed knowledge of the facts upon which its invalidity was ultimately determined. But apparently it was not able to choose the appropriate means of proving these facts. It cannot be said to have supplied its services under a mistake as to the facts, and we can see no just reason for allowing it to shift the burden of the experiment to the shipper.
As a further test of the plaintiff’s position, it is proper to inquire what the situation would be had the suit to determine the constitutionality of the rate statute been begun by the carrier as one to enjoin the execution of the law. Had relief been denied in such a proceeding, and later, after a reasonable period of experimentation, had the injunction been- issued by the United States Supreme Court, preventing’ the state- officers from enforcing the law, manifestly the “coercion,” compelling the carrier to apply the statutory rate during the period of experimentation, would not have been of a judicial, but rather of a legislative,, character. Its position would have been precisely that of any individual who yields obedience to an unconstitutional law and sustains a loss in so doing. It could not shift this loss to another who was justified in contracting with it, upon the supposition that its yielding was. voluntary.
If obligation rests upon the defendant as a matter of law it is wholly because of the fact that the state of North Dakota, through its legislature, has denied to the plaintiff rights secured to it by the 14th *79Amendment to the Federal Constitution. It must be borne in mind that the amendment is intended as a security against any action by the state which may result in the confiscation of property. It does not secure to the individual or the corporation any particular remedy for the enforcement of the right, but it presupposes that ordinary legal remedies will be adequate. If, however, supplementary action is deemed necessary in order to give greater security, Congress is given authority to make appropriate provision to that end. The Civil Rights cases have amply defined the powers of Congress in this connection. Civil Rights Cases, 109 U. S. 3, 21 L. ed. 835, 3 Sup. Ct. Rep. 18. In legal theory, the remedies provided to prevent the violation of the rights secured are adequate. They are the usual remedies available in state and Federal courts, and they have never been extended so as to embrace cases of civil liability flowing incidentally from prohibited state action. The right to so extend them is even denied to Congress. Ibid. Nothing is clearer than that the amendments (13th, 14th and 15th) do not compromise a code of remedial law, according to which reparation may or must be made for every temporary denial of a right so secured, and that the amendments spend their force in permitting state action to be set aside when it involves a violation of the amendments, and when the right is sought to be vindicated in the ordinary channels. The remedial law, as between individual suitors, is left entirely untouched and remains subject to such imperfections as are inherent in a judicial system that is compelled to respect practical considerations in measuring individual rights. Theoretically, there would be no occasion for fastening a liability upon an individual defendant because a state had confiscated the plaintiff’s property. The 14th Amendment contemplates that such action can and should be entirely prevented by a resort to appropriate legal remedies.
In so far as the complaint may be based upon a supposed right to collect a reasonable rate during the period of experimentation, it entirely ignores the effect of the decree of the United States Supreme Court. While the decree was based upon evidence covering a certain period of time, and in this sense looks backward, it nevertheless operated in the future as well. In reality, the plaintiff’s whole case seems properly hinged upon the real meaning and effect of the first decree of the United States Supreme Court.
*80The matter that was settled in that suit was the right of the state to an injunction, and it was found that the state was entitled to the relief sought. Neither the state court nor the United States Supreme Court saw fit to impose any terms or conditions. Thus, so far as the party adverse to this defendant is concerned, the decreeing of the mandatory injunction was absolute, and its effect was to compel the plaintiff herein, among others, to apply the statutory rate until such time as it might obtain relief from the terms of the decree, at the peril of contempt of court. The decree was not interlocutory in any sense, but final; nor do we find that there is anything in the subsequent decree of the same court dissolving the injunction and nullifying the statutory rates which amounts to a qualification of the original decree, except as to the future. Northern P. R. Co. v. North Dakota, 236 U. S. 585, 59 L. ed. 735, L.R.A.1917F, 1148, P.U.R.1915C, 277, 35 Sup. Ct. Rep. 429, Ann. Cas. 1916A, 1.
While the Supreme Court of the United States, in the case of Missouri v. Chicago, B. & Q. R. Co. 241 U. S. 533, 60 L. ed. 1148, 36 Sup. Ct. Rep. 715, explained quite thoroughly the meaning of a decree such as the one involved here, it expressly refrained from deciding whether oi-not excess rates paid pending a decision as to the constitutionality of a rate-fixing statute were recoverable in the absence of a condition to that effect, imposed when the injunction was issued. So that, in dealing with this question, we must dispose of it without an authoritative interpretation of the original decree by the court which entered it. But in the light of well-considered precedent, we think the correct interpretation is that the decree was absolute and bound the plaintiff herein for the time being, and also that the damages flowing therefrom were within the rule of damnum absque injuria. In the case of Russel v. Farley, 105 U. S. 433, 26 L. ed. 1060, Mr. Justice Bradley stated the principle of nonliability, in such a case as follows: “Where no bond or undertaking has been required, it is clear that the court has no power to award damages sustained by cither party in consequence of the litigation, except by making such a decree in reference to the costs of the suit as it may deem equitable and just . . . and if the legal, right is doubtful, either in point of law or of fact, the court is always reluctant to take a course which may result in material injury to either party; for the damage arising from the act of *81the court itself is damnum absque injuria, for which there is no redress except a decree for the costs of the suit, or, iu a proper case, an action for malicious prosecution. To remedy this difficulty the court, in the exercise of its discretion, frequently resorts to the expedient of imposing terms and conditions upon the party at whose instance it proposes to act. The power to impose such conditions is founded upon, and arises from the discretion which the court has in such cases, to grant or not to grant the injunction applied for. It is a power inherent in the court as a court of equity, and has been exercised from time immemorial.”
Where the enforcement of a statutory rate is enjoined, pending an ultimate determination of its validity, the proceedings from the beginning are predicated upon the right of the shippers to command the services at the rate prescribed, and the injunction is only issued to prevent irreparable loss in case the prescribed rate is ultimately held illegal. It follows from this that, when such a suit is determined adversely to the carrier, the shipper may recover whatever difference there may be between the statutory rate, and the rate collected during the progress of the suit. But it is nevertheless appropriate for the court, in enjoining the operation of a statute, to require a bond as an added protection. The right of action upon the bond, however, is not exclusive. Bellamy v. St. Louis, I. M. & S. R. Co. 136 C. C. A. 442, 220 Fed. 816. Where, on the other hand, at the end of an unsuccessful suit, the carrier is restrained from violating the terms of a rate statute, it is manifest that any damages it may sustain through compliance with the injunction are not recoverable. Were the rule otherwise, the injunction, which is merely a continuing expression of the judgment of the court that the statutory rate must be applied, is a judgment deprived of its force as an adjudication of the rights of the parties. The error in the plaintiff’s contention inheres in the failure to recognize the injunction as being the continuing expression of the court until such time as it may be modified or dissolved by a new judgment or decree. During such time, it is impossible that there could have been any other measure of the rights and obligations of the parties than that provided in the decree itself.
In so far as the practice of the United States Supreme Court in qualifying decrees in rate cases as being “without prejudice” sheds light *82upon the question in hand, it seems to indicate that the transactions following the entry of such a decree shall be controlled by the prescribed rate where a decree enjoining it has been reversed, or by a rate otherwise lawfully fixed where a decree enjoining the prescribed rate has been affirmed. In the first cases in which such decrees were entered (Knoxville v. Knoxville Water Co. 212 U. S. 1, 53 L. ed. 371, 29 Sup. Ct. Rep. 148; Willcox v. Consolidated Gas Co. 212 U. S. 19, 53 L. ed. 382, 48 L.R.A.(N.S.) 1134, 39 Sup. Ct. Rep. 192, 15 Ann. Cas. 1034) decrees of the lower courts enjoining the prescribed rate were reversed, and the causes remanded with directions to dismiss the bills without prejudice. The entry of such decrees was thought appropriate for the reason that practical experience with the rates in actual operation might result in enabling the companies affected to show, as they had not previously been capable of demonstrating, the confiscatory character of the rates. In Louisville v. Cumberland Teleph. & Teleg. Co. 225 U. S. 430, 56 L. ed. 1151, 32 Sup. Ct. Rep. 741, it Avas simply stated that the whole question Avas so much in the air that the court did not feel authorized to let the injunction stand; consequently. the decree was reversed “without prejudice.” In the case of Des Moines Gas Co v. Des Moines, 238 U. S. 153, 59 L. ed. 1244, P.U.R.1915D, 577, 35 Sup. Ct. Rep. 811, Avhile the court affirmed the decree of the lower court dismissing the bill of the utility company, it modified the order to the extent of providing that the dismissal should be “without prejudice.” This modification was made in “view of the fact that ordinarily time alone can satisfactorily demonstrate . . . wffiether or not the rates established Avill prove so unremunerative as to be confiscatory in the sense in Avhich that term has been defined in rate-making cases.” In all of the foregoing cases, it will be noted- that the qualification “without prejudice” was attached to a final order of dismissal. In the Missouri Rate Cases (Knott v. Chicago, B. & Q. R. Co.) 230 U. S. 474, 57 L. ed. 1571, 33 Sup. Ct. Rep. 975, and in the North Dakota Rate Case, Northern P. R. Co. v. North Dakota, 216 U. S. 579, 54 L. ed. 624, 30 Sup. Ct. Rep. 423, the final decrees seem to presuppose the continued pendency of the litigation. In three of the Missouri rate cases, where the injunction against the statutory rate Avas allowed to stand, the court provided that “the Railroad and Warehouse Commissioners, and the attorney *83general of the state, may apply at any time to the court by bill or otherwise, as they may be advised, for a further order or decree whenever it shall appear that, by reason of a change in circumstances, the rates fixed by the state’s acts are sufficient to yield to these companies reasonable compensation for the services rendered.” A similar decree was entered in the North Dakota case, where the court allowed the statutory rates to continue in effect. Whether the order be one dismissing a bill “without prejudice” or whether it be in the nature of a modification of a final decree permitting subsequent proceedings in the same case, it seems to be interpreted as affecting the rights of parties in the same way. In Missouri v. Chicago, B. & Q. R. Co. 241 U. S. 533, 60 L. ed. 1148, 36 Sup. Ct. Rep. 715, in answering the contention that the reservation “without prejudice” left the whole subject open for renewed attack, the court, speaking through Chief Justice White, stated that the proposition contended for disregarded “the foundation upon which such a reservation came to be applied,” and further criticized the contention on the ground that it treated “the reservation without prejudice as looking backward and overthrowing that which was concluded by the decree, instead of considering it in its true light; that is, as looking forward to the future and providing for conditions that might then arise.”
The foregoing reference to the qualified decrees and to the reason which seems to have moved the court to enter them seem to indicate clearly that, while the decree was absolutely binding as an adjudication of the rights of the parties down to the time of its entry, it also had the effect of letting the future take care of itself. As to the future, therefore, adopting the construction of the decree most favorable to the plaintiff in this suit, it has simply rendered the service at a rate which both the legislature and the judiciary have determined to be applicable, and it has rendered the service without any other contract on the part of the shipper than would arise from the mere delivery of his goods for transportation according to the prescribed rates. The prescribed rates are either applicable or they are not applicable at the time the goods are delivered for shipment. The legislature and the Supreme Court of the United States have considered that they are applicable; and during the period embraced in this controversy it is inconceivable that either the shipper or the carrier should have been *84allowed to question it, except in the manner allowed by the Supreme Court When that court finally dissolved the injunction, it did not reverse its prior judgment, nor, it seems to us, did it profess to give to the carriers any rights with respect to past shipments that did not exist at the time they were made. These rights were governed by the former decree.
This case is readily distinguishable from that of C. L. Merrick Co. v. Minneapolis, St. P. & S. Ste. M. R. Co. 35 N. D. 331, 160 N. W. 140. In that case, the shipper was allowed to recover the difference between the rate prescribed and collected by the carrier and the statutory rate upon shipments made after the statute went into effect and before the carrier was restrained from violating the statute; whereas, here, the carrier seeks to recover for having done exactly that which it was compelled to do by the decree of the court as a condition to being permitted to secure a dissolution of the injunction. In a case in which a shipper has been permitted to recover the difference between a rate charged and some lower rate, the result has been merely to give to the shipper the benefit of a violated regulatory measure, with which the carrier was not, for the time being, complying. For all purposes of such a situation, the regulatory provision fixes the absolute criterion of reasonableness, and, it having been prescribed by competent authority, a departure therefrom is a distinct breach of the obligation of the carrier. In the case at bar, the effect of the first judgment of the United States Supreme Court was to fix a criterion of reasonableness based upon the statute which should control until the decree might subsequently be modified.
In addition to tho reasons assigned, there are strong practical considerations which weigh against the maintenance of an action such as the one at bar. In the case of Van Patten v. Chicago, M. & St. P. R. Co. 81 Fed. 545, which was a suit to recover damages on the ground that the charges exacted by the carrier were unreasonable, it was held that it was competent and proper for the carrier to show in defense that, in obedience to the Interstate Commerce Act, it adopted, printed, and posted a schedule of rates, and that the charges complained of were in accordance with those contained in the schedule. Commissioner Prouty of the Interstate Commerce Commission later criticized this result (Cattle Raisers’ Asso. v. Ft. Worth & D. C. R. Co. 7 Inters. *85Com. Hep. 553) on the ground that, under the Interstate Gommerce Act as it existed at that time, the effect of the decision was to entirely cut off the right to recover any portion of an excessive or extortionate charge. Conceding that the opinion referred to would, under the thou existing state of the law, have had the effect pointed out by Commissioner Prouty, it may be open to the criticism of being extreme. But the practical considerations referred to by Judge Shiras afford persuasive reasons for holding the first decree of the United States Supreme Court to have been binding upon the parties until changed, and the damages incident to a compliance therewith to come within the rule of damnum absque injuria.
Judge Shiras, in the case referred to (page 551), said: “In the present case, however, the proposition of the plaintiff is that, after the carrier, in obedience to the requirements of the act, has adopted, printed, and posted schedule of rates [which was done in this case under § 4727, Comp. Laws 1913], and for the past five years has received and transported grain, charging the schedule rates therefor, and the shipper, without protest or demur, has delivered his grain for shipment, knowing the schedule rate, and has paid the charges in conformity with the established rate, he may now, and at any time within the period of the Statute of Limitations, bring an action at law for damages, not on the ground that more than the schedule rate was exacted, or that the schedule itself provided for unequal, and therefore unjust, rates, but solely upon the ground that the schedule rates, though uniform and properly proportioned, were greater than they should have been; and thus the question is presented whether the Interstate Commerce Act, considered as a whole, authorizes and provides for an action of this kind. If it can be maintained, it results in the holding that it was the intent of Congress to place upon the courts and juries of the country the duty and burden of establishing the rates of transportation for interstate commerce, and upon the common earlier the burden of transportation, with the right to ultimately retain as pay therefor the rate fixed by the verdict of a jury rendered perhaps five years after the rendition of the services. How is it possible for a jury to pass understandingly upon the question which inheres in the establishment of a properly proportioned and equalized schedule of transportation rates ? . . . Now the theory of the plaintiff is that *86the jury must inquire into and determine what the reasonable rate wa3 for each shipment when made, and, by comparing the reasonable rate thus fixed by the jury with that actually charged, to determine whether the plaintiff is entitled to damages, and, if so, to ascertain the amount on each shipment made. It is self-apparent that, no matter how intelligent the jury might be, nor how conscientiously and carefully they might endeavor to deal with the problem thus submitted to them, it would be wholly impossible for them to reach a proper verdict under such circumstances.
“But, suppose the case involved but a single shipment, would the difficulty be remedied, if the theory of the plaintiff is to prevail ? How could the jury fairly and understandingly deal even with the case of a single shipment, provided the duty is placed upon the jury of determining what a fair and reasonable charge for the particular service would be, unless some standard, already recognized and established, is given them for their guidance? It is impossible for the jury to deal with the questions of the total cost of building, equipping, and operating tho line of a railway as a whole, the proportionate cost of the particular transportation in question, the total amount of business done over tho entire system, the total burden properly to be laid upon the total business for transportation charges, and the proper proportionate share which the particular shipment should bear.”
It is true that these practical considerations should not have weight as against a clear legal right; but since they inhere in, and are so thoroughly characteristic of, the particular matter in controversy, it is only reasonable to suppose that they were present in the mind of the court when the decree in question was entered, and that the court purposely granted the relief unconditioned as to the consequences of a possible future modification. Surely the United States Supreme Court did not intend that, during the entire period its first decree should be in operation, the parties whose business would be affected favorably or unfavorably by the experiment should be left to the uncertainties incident to numerous subsequent jury trials in order to determine the rate applicable to shipments of coal.
The order appealed from is affirmed.
