MARBLE COMPANY
v.
RIPLEY.
Supreme Court of United States.

*350 The case, of which the transcript filled 904 printed pages, was elaborately argued by Messrs. B.R. Curtis and E.J. Phelps, for the Rutland Marble Company; and by Messrs. George F. Edmunds and W.M. Evarts, contra.
Mr. Justice STRONG, having stated the case, delivered the opinion of the court.
The first question presented for our consideration is whether the pleadings and proofs exhibited a proper case for an injunction upon the defendants, Ripley and Barnes, against disturbing the complainants in their right to take possession, occupy, and use the property entered upon by the said defendants, and against continuing the occupation which they had commenced of the quarries and other property, real and personal, of the company. The solution of this depends upon another question, which is, whether the entry made by Ripley, through his agent, Barnes, on the 26th day of April, 1864, was lawful under the circumstances in which it was made.
It is to be observed that the contract of January 22, 1850, between Ripley and Barnes, was in a very practical sense a contract of partnership, and that to Barnes's position under *351 it the complainants have succeeded. By its terms each of the parties was bound to contribute to a common enterprise. Each had his own duties to perform. Barnes was to furnish the marble needed for the mill, and Ripley was to bestow his own labor and care in manufacturing it for the market and selling it. When this had been accomplished the net proceeds of sale were to be equally divided. Neither of the parties had a right to interfere with the specified duties of the other so long as that other discharged his obligations under the contract. But they had a common interest in the business carried on, quite as truly as if theirs had been an ordinary partnership. Any unauthorized attempt by one to oust the other from the position and rights assigned to him by the contract was, therefore, not only a breach of their agreement, but a fraud upon the relation they had assumed to each other. Such a wrong it is the province of a court of equity to prevent. A chancellor will interfere by injunction to restrain one partner from violating the rights of his copartner, even when a dissolution of the partnership is not necessarily contemplated.[*]
Primâ facie, the entry of Ripley upon the quarry property and the consequent deforcement of the complainants was an invasion of their rights as owners of the land, and as jointly interested with him in the marble business. The burden is upon him, therefore, to show that his entry was justifiable. Has he shown it? Under the reservation in Ripley's deed, and under the contemporaneous agreement, his right to enter existed only in case Barnes, or his successors in the title, should fail or refuse to fulfil the conditions and stipulations of the contract; that is, should fail or refuse to deliver the marble as required by it. A right to enter for any other cause is not claimed. After a careful examination of the evidence we do not find that there had been any such failure on the part of the complainants to deliver marble prior to April 26, 1864, as justified Ripley in entering upon their possession. They were not bound to keep in full supply *352 the mill which he then had. The contract had reference to a supply of the mill as it was in 1850, when its capacity was less than 150,000 feet per annum. And when, afterwards, he enlarged his mill so that he could saw 300,000 feet, nothing in the contract required Barnes, or his alienees, to keep the enlarged mill supplied. The obligation was only to furnish 150,000 feet per annum, as it might be wanted to supply the old mill. Nor did the contract require that any defined portion of the whole quantity should be delivered at any specified season of the year. Undoubtedly its spirit demanded that the deliveries should be reasonable. But it is in evidence that quarrying marble must be principally in moderate or warm weather, when there is no frost. It is, therefore, a reasonable construction that the parties intended the deliveries should be greatest in the summer and fall. Yet the evidence is, that the complainants delivered at his mill, during the months of February, March, and April of 1864, more than 26,000 feet, besides other blocks which he refused to receive. In fact a considerably greater quantity was delivered. All this was between February 1st (when the modification of the contract before mentioned expired) and the 3d of April. This was in excess of a ratable proportion of what the company was bound to quarry and deliver. After the 2d of April there was an interruption of deliveries, caused by a general turn-out of the workmen at the quarries, of which we shall have more to say hereafter. But what is most significant and convincing that there was no failure on the part of the company is Ripley's own sworn answer to their bill. It appears from what he himself states in this answer, that the reason for his entry was, not that there had been any failure or refusal to supply his mill with marble, so far as he had a right to claim it, but that the marble company disregarded his opinions, and he was apprehensive they would not be able to induce the laborers to return to work. It is plain that for such reasons neither the reservation in his deed nor the provisions of the contract gave him any right of entry. His intrusion upon the complainants' possession was, therefore, entirely unjustifiable, and a *353 wrong the continuance of which a court of equity may well restrain.
We are also of opinion that his entry was not made in good faith, merely to supply himself with marble. Very soon after the modified contract came to an end he set up claims, some of which, at least, had no foundation in the contract. On the 15th of February he gave notice that he claimed a right to divide every lot of blocks, at all times thereafter, when taken from the quarry referred to in his deed and in the contract, insisting upon a right to the first choice; and this, though he had elected forever to take all his marble from the south opening, which he had required to be made under the alternative provision of the contract. This was either claiming inconsistently with his demand for all his marble from that opening, or it was, in effect, requiring the company to take therefrom twice as much as was necessary to supply the 150,000 feet for his mill. When the demand was resisted it was renewed, though without right. Differences of opinion also arose between the parties respecting Ripley's obligation to receive particular kinds of marble, respecting his right to demand payment for unloading it at his mill, and respecting his obligations to pay for quarrying and hauling. We do not enter now upon any consideration of the inquiry which of the parties was right. It is sufficient to notice that there were differences. It was while they existed, early in April, the strike of the laborers occurred. The evidence establishes beyond any reasonable doubt that Ripley advised the agents of the company to hold out against the strike, and that when told the mill contracts made a difficulty, he said he would rather go without marble six months, or a year, than that the company should submit to the strikers. Yet at this time when giving this advice and making these professions, he was preparing secretly to make an entry on the property. He was having drills made at least a week or ten days before he made his entry at night, concealing the purpose for which they were made, and his design to enter. When told that he was aiding the strike, as the men understood he was intending to set them at work, *354 he replied the men did not know but that he was going to quarry somewhere else. Meanwhile he was himself refusing, or at least neglecting to pay what he was bound to pay, at the time when it was due. It is impossible to read the evidence without being convinced that he intended to secure the possession of the property by surprising the complainants, and thereby force them to assent to his demands and his interpretation of the contract. Such being the conclusions to be drawn from the evidence, we cannot doubt that the injunction decreed by the Circuit Court was correctly awarded.
It was, however, too broad. It restrained the defendants, Ripley and Barnes, not only from the further occupation or possession of the premises and property described in the bill, and from any interference therewith, but it enjoined them against hindering or disturbing the complainants from taking possession of, occupying and using the same, until the further order of the court. The effect of this is to deny to Ripley the right of entry reserved in his deed, and forbid his exercising it, though the complainants should hereafter wholly refuse to deliver any marble, unless the court by a future order shall allow an entry. This is probably more than was intended. The decree should be modified so as only to enjoin against an entry for any cause heretofore existing, leaving Ripley to enjoy his reserved right hereafter entirely untrammelled.
We proceed next to inquire whether there is any sufficient reason for decreeing a cancellation of the contract of January 22, 1850, as prayed for by the marble company. This is a call for an exercise of the highest chancery power, a power most frequently exerted in cases of fraud, accident, or mistake. The grounds upon which the company rest their claim that the contract may be decreed to be rescinded and cancelled are, that Ripley has not performed the duties which it imposed upon him; that though it was, when made, intended to operate for the equal benefit of both parties, it has become, in the progress of time, oppressive and burdensome *355 to the complainants, or, as they denominate it, unconscionable; that it makes them partners with Ripley, or his successors in title to the mill, whether they will or not; and that, if corporations cannot enter into partnership, they cannot purchase the lands subject to the obligation of becoming partners, and therefore the contract restrains the alienability of the property.
Before proceeding to a consideration of these it is proper to remark that the agreement is inseparable from the deed for the land made by Ripley to Barnes. They were made at the same time, and they are parts of one arrangement. What is asked, therefore, is, not to rescind an entire contract, but to strike out of it a part which has become onerous to one of the parties. It is clear that the rights secured to Ripley by the agreement were a part of the consideration for his grant of the land, and so it was understood at the time his deed was made. If there were nothing else to show this, it is made apparent by the reservation in the deed of a right of entry to secure the fulfilment of the stipulations of the agreement. But the deed was an executed contract. It conveyed the title to the grantee. If, therefore, the agreement is rescinded by a decree of the court, the consideration of the grant is taken from the vendor after his conveyance has taken effect, and yet his grant is enforced. It is believed that such action by a court of equity is quite unprecedented. It has been ruled that when a party seeking to set aside a conveyance made by him has received part of the consideration, he must return it before a court of equity will cancel the conveyance.[*] That one party to an executory contract, partly executed, has violated his engagements, is generally no sufficient reason for a decree by a court of equity, at the suit of the other party, that the contract shall be annulled. Certainly it is not in the present case. If the contract has been broken by Ripley, the marble company has an adequate remedy at law. Nor is it any reason for rescinding the contract that it has become more *356 burdensome in its operation upon the complainants than was anticipated. If it be, indeed, unequal now, if it has become unconscionable, that might possibly be a reason why a court should refuse to decree its specific performance; but it has nothing to do with the question whether it should be ordered to be cancelled. It is not the province of a court of equity to undo a bargain because it is hard. Nor have the other reasons assigned in support of the complainants' prayer for cancellation any more weight in view of the circumstances of the case. The marble company have, by their own voluntary act, placed themselves in the position they occupy. With a full knowledge of the reservation in Ripley's deed to Barnes, and of the contract, the performance of which the reservation was intended to secure, they purchased the quarries. They purchased expressly subject to the rights guaranteed to Ripley, and they undertook with their grantors to perform the promises Barnes had made, so long as they held the land. At the time when they purchased, the contract had been in operation for years, and they knew its effect. It is fair to presume that the burden of the contract was considered in fixing the price they paid. They are, therefore, not in a condition to ask for its rescission, and the Circuit Court rightly refused to decree a cancellation.
The next question is, whether Ripley, the defendant, was entitled, upon his cross-bill, to a decree against the marble company for a specific performance of the contract. The court below substantially directed such performance, and from that decree the marble company have appealed, and they now urge that the contract, though supposed to be fair and equal when made, has, in the lapse of time, and by the operation of unforeseen causes, arising from changed circumstances, become exceedingly unfair, unreasonable, and unconscionable, so that a decree for its specific performance would tend to their oppression and ruin. It may be doubted, however, whether the hardship of the contract is any greater than must have been contemplated when it was made. It is *357 not unconscionable because Ripley obtains a larger profit from it than was at first expected, or because the other party obtains less. Those were contingencies, the possibility of which might have been foreseen. It could not have escaped the thought of the contracting parties that the expense of quarrying might possibly increase, and that the expense of sawing and preparing for market might either increase or diminish in the progress of time. Of that they took their chances. Besides, it is by no means clear that a court of equity will refuse to decree the specific performance of a contract, fair when it was made, but which has become a hard one by the force of subsequent circumstances or changing events. Mr. Fry, in his work on Specific Performance,[*] asserts that "the question of the hardship of a contract is generally to be judged of at the time at which it is entered into; that if it be then fair and just, it will be immaterial that it may, by the force of subsequent circumstances or change of events, have become less beneficial to one party, except when these subsequent events have been in some way due to the party who seeks the performance of the contract." Judge Story, indeed,[] states the rule somewhat differently, and there are some cases that support his statement; but the rule as stated by Mr. Fry must be applicable to contracts that do not look to completed performance within a defined or reasonable time, but contemplate a continuous performance, extending through an indefinite number of years, or perpetually.
There are other objections, however, to a decree for a specific performance in this case which are more serious. Such a decree is not a matter of right. It rests in the sound discretion of the court, and generally it will not be made in favor of a party who has himself been in default. In Story's Equitable Jurisprudence,[] it is said that "in cases of covenants and other contracts, where a specific performance is sought, it is often material to consider how far the reciprocal *358 obligations of the party seeking the relief have been fairly and fully performed. For, if the latter have been disregarded, or they are incapable of being substantially performed on the part of the party so seeking relief, or from their nature they have ceased to have any just application by subsequent events, or it is against public policy to enforce them, courts of equity will not interfere." To the same effect are Smith's Principles of Equity;[*] Thompson v. Tod,[] Lewis v. Wood,[] and many other cases. Applying these principles to the case in hand, it would appear that the conduct of the cross-complainant has not been such as to justify the court in decreeing a specific performance, at his suit, against the marble company. Without relying upon his alleged unfounded claims set up from time to time, or his alleged refusals or failures to make the payments due from him at the times required by the contract, or his alleged comfort given to the turn-out of the workmen, and his advice that the company should resist it, his unlawful and unwarranted entry and ouster of the marble company was such an invasion of the contract as leaves him no standing as a complainant asking for its performance in a court of equity.
Another serious objection to a decree for a specific performance is found in the peculiar character of the contract itself, and in the duties which it requires of the owners of the quarries. These duties are continuous. They involve skill, personal labor, and cultivated judgment. It is, in effect, a personal contract to deliver marble of certain kinds, and in blocks of a kind, that the court is incapable of determining whether they accord with the contract or not. The agreement being for a perpetual supply of marble, no decree the court can make will end the controversy. If performance be decreed, the case must remain in court forever, and the court to the end of time may be called upon to determine, not only whether the prescribed quantity of marble has been *359 delivered, but whether every block was from the right place, whether it was sound, whether it was of suitable size, or shape, or proportion. Meanwhile the parties may be constantly changing. The marble company are liable so long as they hold the land, and Ripley's rights exist only while he holds the mill. It is manifest that the court cannot superintend the execution of such a decree. It is quite impracticable. And it is certain that equity will not interfere to enforce part of a contract, unless that part is clearly severable from the remainder.[*] Many of the difficulties in the way of decreeing specific performance of a contract, requiring, as this does, continuous personal action, and running through an indefinite period of time, are well stated in The Port Clinton Railroad Company v. The Cleveland and Toledo Railroad Company.[]
Another reason why specific performance should not be decreed in this case is found in the want of mutuality. Such performance by Ripley could not be decreed or enforced at the suit of the marble company, for the contract expressly stipulates that he may relinquish the business and abandon the contract at any time on giving one year's notice. And it is a general principle that when, from personal incapacity, the nature of the contract, or any other cause, a contract is incapable of being enforced against one party, that party is equally incapable of enforcing it specifically against the other, though its execution in the latter way might in itself be free from the difficulty attending its execution in the former.[]
But what is a still more satisfactory reason for withholding a decree for specific performance is, that the party who asks for it has an entirely adequate remedy provided by the reservation in his deed, and by the contract itself. In addition to his remedy by suit at law, he has a right of entry and the privilege of supplying himself with marble, as much as he may want, if the owners of the land do not fulfil the *360 conditions and stipulations of the contract. He may take marble without making payment for it, and in case of such entry he may hold possession until the tenants of the fee are ready and willing to carry out the agreement, and until he has been compensated for all his expenditure. This is a remedy more adequate and full than any decree for specific performance could give him, and it renders such interference of a court of equity entirely unnecessary.
For these reasons we are of opinion that the Circuit Court should not have decreed performance in specie of the contract, but should have left the cross-complainant to his action at law, or to the remedy reserved in his deed.
It is true that the marble company, on the 18th of June, 1864, gave notice to Ripley that they would claim that the facts set forth in their bill amounted to a permanent breach and violation on his part of the contract, authorizing them to treat it as rescinded, and that they therefore rescinded it, asserting that they had always performed it on their part until it was thus violated and broken by him. But this was after his wrongful entry, which certainly relieved them for a time from delivering marble, and the notice in no way interferes with any remedy he may have at law, or with any right he has to enter under the reservation in his deed.
The decree, so far as it orders specific performance, will therefore be reversed, as also all the decretal orders that direct the mode of performance.
We have thus disposed of all the questions raised by the appeal of the complainants, The Rutland Marble Company, and of most of those raised by the appeal of the defendant, Ripley. Two or three questions remain to be considered. It is sufficient to say, in answer to the second specification of his appeal, that we do not perceive that he was required to pay the company's share of the money received by him from the marble business any more rapidly than the contract, giving to it a reasonable construction, demanded.
In the sixth specification it is averred that the decree is *361 erroneous, in that it omits to order and direct that The Rutland Marble Company, their agents, servants, and assigns, be enjoined from selling or disposing of marble taken from said quarry of said company. Though the appeal is in these broad terms, it is presumed the appellant does not mean to be understood as claiming that the marble company should be enjoined against selling as much marble as the quantity furnished by them for the mill. If this is not so, then the construction he would have given to the contract is that the tenants of the fee must quarry every year 300,000 feet, and deliver one-half thereof at the mill, leaving the remainder unsold and undisposed of. This is a construction so unreasonable and so at variance with the words of the contract, that it needs only mention to show its inadmissibility. Assuming, then, it to be meant that the court should have enjoined against a sale of marble from the land greater in quantity than that which was required by the contract to be delivered at the mill, we are of opinion the claim cannot be maintained. It has been argued in support of it that the evidence shows the quarry to be exhaustible within a definite number of years; that the contract contemplated a perpetual supply for the mill, or a supply so long as the marble shall last, while the quarry shall be worked in the manner contemplated and prescribed by it; and hence that taking out marble and disposing of it in greater quantities than the mill requires, with a right of choice of blocks in Ripley, is an invasion of his right.
The argument is faulty in several particulars. It assumes that the contract prescribed a mode of use of the quarries exclusive of any other. Such is not the agreement. It bears upon its face the evidence that supplies of marble to other consumers than Ripley's mill was contemplated. There certainly is no express restriction of the quantity which the owners of the land may take out, and restriction upon the absolute rights of ownership in fee is not to be raised by mere implication. When Ripley required, under the last provision of the agreement, all his marble to be furnished from the south opening on the lot, and when, in obedience *362 to his demand, the opening was made by Barnes, it should require unambiguous language to satisfy a court that Barnes and his successors in the title were excluded from taking marble from any other opening for the purpose of sale.
The argument also misapprehends the nature of such a right as Ripley's, even though it be conceded that it was intended to provide for a perpetual enjoyment of a marble supply. Neither the contract nor the reservation in his deed gave him a corporeal interest in the marble in situ. It was not a grant to him of the marble, or a grant of a right to quarry and take it all. If his interest was real in any sense, which may be doubted, it was incorporeal. Of course it was not exclusive of the right of the owners of the land to take marble on their own account ad libitum. In Lord Mountjoy's case, reported by Godbolt,[*] by Leonard,[] in Coke Littleton,[] by Moore,[§] and more fully by Anderson,[] a leading case, the words of the reservation were:
"Provided always, and it is covenanted, granted, concluded and agreed between the said parties to this indenture, and the said John Brown and Charles (the grantees), and their heirs covenant and grant to and with the said Lord Mountjoy, his heirs and assigns, by these presents, in form following, that is to say, that it shall be lawful for the said Lord Mountjoy, his heirs and assigns, at all times hereafter, to have, take, and dig in and upon the heath ground of the premises, from time to time, sufficient ores, heath, turves, and other necessaries for the making of alum and copperas."
Here was a reservation from grantees and their heirs to a grantor, his heirs and assigns, quite as large as in the present case. Yet it was held an incorporeal hereditament, and not a grant of an exclusive right. It was likened to a grant of common sans nombre, leaving the grantors a right to dig and take ore, though their so doing might exhaust it. Chetham v. Williamson,[¶] is another case equally decisive to the same effect. Other decisions asserting the same doctrine *363 are at hand: Caldwell v. Fulton,[*] Johnston Iron Company v. The Cambria Iron Company,[] Gloninger v. The Franklin Coal Company.[] In all of them the covenants ran with the land. The grants were of undoubted real interests. They contemplated a perpetual supply to the grantees as plainly as it was contemplated in this case. The rights of the grantees were not limited, as here, to any defined quantity, and yet it was held they did not interfere with the right of the grantors to take ore, coal, &c., from the property out of which the incorporeal interests issued, and to take it without stint. The appeal of the cross-complainant cannot therefore be sustained.
Nor, under the circumstances of the case, can the marble company be decreed to account for failures to supply the marble required by the contract to be delivered at the mill, if there have been such failures. Holding as we do that there can be no decree for a specific performance, and that Ripley is not entitled to an injunction against selling marble from the quarry, the substantial basis of the defendant's cross-bill fails, and having disturbed the plaintiffs' possession wrongfully, and thereby interfered with their power to perform the contract, he is not in a situation to invoke equitable aid. If he has any claim to damages for a breach of the contract, it must be asserted at law, and there his remedy is complete.
It remains only to add, what must now be apparent, that that part of the decree which directed Ripley to pay the taxable costs, except such as accrued from the portion of the complainants' bill which sought to annul the contract, was correct.
DECREE REVERSED, and the cause remitted with directions to enter a decree in accordance with the opinion above given. The costs of the appeals to be divided, and one-half be paid by each of the parties.
