To this cross bill the Pullman Company Messrs. Frank P. Prichard and John The demurrers were overruled with leave to present the questions on final hearing, and the Pullman Company then answered the cross bill. Among other things it set up that the agreement in question was void, "and that being null and void between the parties hereto because of such character of the agreement, it cannot be made the lawful 171 U. S. Mr. Justice Peckham delivered the opinion of the court: The motion to dismiss the appeal in this case is now before the court. Counsel for the Pullman Company took the appeal directly from the circuit court to this court on the theory that the case involved the construction or application of the Constitution of the United States, because of the holding of the court below that the cause of action alleged by the Central 111 Company in its cross bill was under the cir- | the impossibility of returning a large portion cumstances a proper subject of equitable cog- of the property which it had received; it an nizance, and counsel claimed it was really nounced its willingness to make substantial nothing but a legal cause of action in regard performance of its contract contained in the to which the cross defendant was entitled to lease, and it asked the court to aid it therein a trial by jury under the Constitution of the by decreeing exactly what it should do for United States. There being room for doubt the purpose of carrying out equitably and in regard to the soundness of such conten- fairly its obligations incident to its termination, the counsel also took an appeal to the tion of the lease under the clause above mencircuit court of appeals, and we think that tioned. The other theory rested upon what by this action he did not waive any right of was a substantial allegation of the invalidity[147, appeal which he would otherwise have had. of the lease as having been made without auWhichever route may be the correct one, thority of law, and therefore in violation of either directly from the circuit court or the corporate duties of the Central Company, through the circuit court of appeals, it is un- and on that account not enforceable against necessary to decide, because the case is now the Pullman Company beyond the obligation properly before us either by appeal or by the of the latter company to make return of just writ of certiorari; and we therefore proceed compensation for the property demised. Upto determine it upon the merits. on that theory the bill asked, not that the court should set aside or cancel the lease, but that it should aid the parties by decreeing just what relief should be given by the complainant to the lessor in the execution of its duty to make some compensation for the property it received and which it stated its willingness to make, and to that end, that an accounting might be had and the amount ascertained that should be paid to the Central Company in discharge of the obligations of the complainant in that behalf. Thus the Pullman Company came into a court of equity and in substance alleged that the lease had been terminated by it under the eighth clause, and it also alleged that the lease was void as ultra vires, and in either event it tendered such relief as the court might think was proper and fair under the circumstances. The Pullman Company, complainant in the original suit, insists that it had the right to discontinue that suit at its own cost before any decree was obtained therein, and the refusal of the court below to grant an order of discontinuance upon its application is the first ground of objection to the decree herein. The general proposition is true that a com[146]plainant in an equity *suit may dismiss his bill at any time before the hearing, but to this general proposition there are some well recognized exceptions. Leave to dismiss a bill is not granted where, beyond the incidental annoyance of a second litigation upon the subject-matter, such action would be manifestly prejudicial to the defendant. The subject is treated of in City of Detroit v. Detroit City Railway Company, in an opinion by the circuit judge, and reported in 55 Fed. Rep. 569, where many of the authorities are collected, and the rule is stated substantially as above. The rule is also referred to in Chicago & Alton Railroad Company v. Union Rolling Mill Company, 109 U. S. 702 [27: 1081]. From these cases we gather that there must be some plain, legal prejudice to defendant to authorize a denial of the motion to discontinue; such prejudice must be other than the mere prospect of future litigation rendered possible by the discontinuance. If the defendants have acquired some rights which might be lost or rendered less efficient by the discontinuance, then the court, in the exercise of a sound discretion, may deny the application. Stevens v. The Railroads, 4 Fed. Rep. 97, 105. Unless there is an obvious violation of a fundamental rule of a court of equity or an abuse of the discretion of the court, the decision of a motion for leave to discontinue will not be reviewed here. Upon an examination of the facts relating to the motion, we think the circuit court was right, in the exercise of its discretion, in denying the same. The original bill was framed really on two theories: One, that by reason of an election male under the eighth clause in the lease, the Pullman Company had terminated the lease, and it was therefore bound under its provisions to return the property which it had received from the Central Company. It stated in its bill A large amount of proof had been taken under the issues made in this original bill and the answer thereto, and before the case was concluded the decision of this court was made in which the lease was declared to be void. The only obligation left under the original bill of complainant after the decision of this court was the obligation to return such portion of the property received by it as the court should determine to be right, or to make some compensation to the Centrai Company for the same. And this obligation it had offered in the original bill to carry out. The Pullman Company had also obtained an injunction in the original suit, restraining the Central Company from commencing further legal proceedings to recover rent under the lease, and after obtaining this injunction and taking the testimony relating to the subject-matter of the original bill, the complainant should not be permitted under these circumstances to dismiss that bill and thus withdraw the whole case from the jurisdiction of the court, and thereby blot out its *tenders of[148] relief contained in its original bill grounded, among others, upon the allegation that the lease was void, and asking the aid of the court to decree the precise terms upon which its obligations to the Central Company might be fulfilled. The denial of the motion was made in connection with the application of the Central Company to file a cross bill in which it would because in unreasonable restraint of trade, and erefore contrary to public policy. ID making the lease the lessor was certainly an much in fault as the lessee. It was argued on the part of the Central Company that even if the contract sued on were void, yet that having been fully performed on the part of the lessor and the benefits of it received by the lessee for the period covered by the declaration in that case, the defendant should be estopped from setting up the invalidity of the contract as a defense to the action to recover compensation for that period. But The further objection is made by the counsel for the Pullman Company that it was er-it was answered that this argument, though ror to allow the cross bill to be filed in this sustained by the decisions in some of the case.

In such case, however, the action is not maintained upon the unlawful contract nor according to its terms, but on an implied contract of the defendant to return, or failing to do that, to make compensation for the property or money which it had no right to retain. To maintain such an action was not The facts which were set up in the cross bill closely affected one of the theories upon which the original bill was filed, viz., the invalidity of the lease. They were relevant to the matters in issue in the original suit, and in seeking affirmative relief the cross complainant is but amplifying and making clearer the foundations for the intervention of equity to affirm, but disaffirm, the unlawful conwhich had been appealed to by the Pullman tract."

Johnson, 1 Cowp. 341, decided in 1775, that "the objection that a contract is immoral or illegal as between the plaintiff and defendant sounds at all times very ill in the mouth of the defendant. It is [151]not for his sake, however, that the objection is ever allowed; but it is founded in general principles of policy, which the defendant has the advantage of, contrary to the real justice, as between him and the plaintiff, by accident, if I may so say. The principle of public policy is this: Ex dolo malo non oritur actio. No court will lend its aid to a man who founds his cause of action upon an immoral or an illegal act.' The cases upholding this doctrine are numerous and emphatic. Indeed, there is really no dispute concerning it, but the matter of controversy in this case is as to the extent to which the doctrine should be applied to the facts herein. Many of the cases are re: ferred to and commented upon in the opinion delivered in the case in 139 U. S. 24 [35: 55], already cited. The right to a recovery of the property transferred under an illegal contract is founded upon the implied promise to return or make compensation for it. For illustrations of the general doctrine as applied to particular facts we refer in the margin to a few of the multitude of cases upon the subject.† or paid for. The former is impossible. The Acting under these directions of the court, "Passing to the consideration of the main ex-question raised in the present reference, viz., what the Central Transportation Company lost by the transfer of its property to the Pullman *Company, the measure of damages[153] as determined by the court requires the mas "(1) What was the value to the Central Transportation Company in 1870 of the property transferred? "(2) What was earned by the Pullman Company between January 1, 1870, and January 1, 1885, from the use of the property transferred? They are substantially unanimous in pressing the view that in no way and in no channels, directly or indirectly, will the courts allow an action to be maintained for the recovery of property delivered under an illegal contract where, in order to maintain such re-ter to ascertain: covery, it is necessary to have recourse to that contract. The right of recovery must rest upon a disaffirmance of the contract, and it is permitted only because of the desire of courts to do justice as far as possible to the party who has made payment or delivered property under a void agreement, and which in justice he ought to recover. But courts [152]will not in such endeavor permit *any recovery which will weaken the rule founded upon the principles of public policy already noticed. We may now examine the record herein and learn the grounds for the recovery which has been permitted, and determine therefrom whether the judgment in favor of the Central Company should be in all things affirmed or if not, then how far the liability of the cross defendant extends, and, if possible. what should be the amount of the judgment against it. In referring the case to the master for the purpose of taking the account between the parties the learned district judge stated the principle upon which the liability of the cross defendant rested. He said: "(3) The difference between the amount so received by the Pullman Company and the rental paid by it to the Central Transporiation Company for the above period. "(4) The total amount to be paid by the Pullman Company, as of January 1, 1885, deduced as above, together with interest thereon from January 1, 1885, to date of final decree.". The master proceeded to determine the value in 1870 of the property then transferred. In ascertaining it he said: "The value of the stock on the street is a positive indication of the estimate placed on the property by the public. That it is not entirely a satisfactory measure of value must be conceded, but in the judgment of the master, supported as it is by the best inde"The property must therefore be returned pendent estimate that the evidence affords, Coppell v.

As the market value of the shares of this stock was made up to some extent, at least, of certain factors which the lessee cannot, under the rules of law, be held responsible for in this case, it follows that such value cannot furnish a safe guide in measuring the respon-[156] sibility of the lessee in an utterly void lease.
