The jury, under the instructions of the court, have either found that the plaintiff, for the commission named, undertook to produce a party ready and willing to make the purchase at such price as might be agreed upon between the defendants and such purchaser when brought together, or they have found that the plaintiff, for a like commission, undertook to procure a purchaser at the price of fifteen dollars per acre *349for tbe farm, and that when the purchaser and the defendants came together, the defendants consented to sell and did sell the property to the purchaser furnished by the plaintiff, at a less price. The former was the agreement as testified to by the plaintiff, the latter that to which defendants testified. There was no testimony tending to establish any other or different agreement between the parties than one or the other of these. The court instructed the jury, if they found from the evidence that the plaintiff contracted to find a purchaser at fifteen dollars per acre for a commission of five per cent., he could not recover unless he found a purchaser who was willing to pay that price, unless the defendants consented to sell, and did sell the property to the purchaser furnished by the plaintiff at a less price. The fact is undisputed that the sale was made at a price less than fifteen dollars per acre. The jury returned a verdict for the plaintiff for the five per cent, commission on the sum for which the land was sold.
The rule of law is not questioned, that a broker, employed to make a sale at a price satisfactory to the seller, is entitled to his commissions when he produces a party who makes the purchase. And it is in general enough, in such case, that the broker produces a party ready to make the purchase at a satisfactory price; and the principal cannot relieve himself from liability by capricious refusal to consummate the sale, or by a voluntary act of his own, disabling him from performance. Moses v. Bierling, 31 N. Y., 462; Kock v. Emmerling, 22 How. (U. S.), 69.
And where the price or other terms of sale are fixed by the seller, in accordance with which the broker undertakes to produce a purchaser, yet if, upon procurement of the broker, a purchaser comes with whom the seller negotiates, and thereupon voluntarily reduces the price of the thing to be sold, or the quantity, or otherwise changes the terms of sale as proposed to the broker, so that a sale is consummated, or terms or condi-, tions offered which the party proposing to buy is ready and *350agrees to accept, tiren and in either such case the broker will be entitled to his commissions at the rate specified in his agreement with his principal. The instruction above referred to was correct in law and properly given. Kock v. Emmerling, supra; Woods v. Stephens, 46 Mo., 555; Lincoln v. McClatchie, 36 Conn., 136. The authorities cited show that wherever the sale is effected through the efforts of the broker, or through information derived from him,-so that he may be said to have been the procuring cause of it, his services are regarded as highly meritorious and beneficial, and the law leans to that construction which will best secure the payment of his commissions, rather than the contrary.
There can be no doubt, in the present case, that the plaintiff was the procuring cause of the sale which was made; but, in order to effect such sale, it seems he was obliged himself to become a part purchaser or joint purchaser of the property with the party whom he brought to the defendants as- a person wishing to buy. He made no concealment, but the defendants were-fully informed of this fact, and the negotiation resulting in the sale to himself .and the party whom he had found thus willing to become joint purchaser with him, was openly carried on with the defendants. The defendants knew all the facts. The written contract of sale was made to the plaintiff and the purchaser procured by him, as joint purchasers. Under these circumstances, a question arises, and, as we think, a very delicate and important one, which is, whether a broker, thus employed to find a purchaser, can in any case himself become the purchaser in whole or in part of the property, and yet claim and recover the commissions agreed to be paid by the seller. The general principle will at once be acknowledged, that a person cannot at the same time be both agent for the seller to make the sale, and purchaser of the property to be sold. The relations' are wholly incompatible with each other, and cannot be combined in the same person. The law will not permit it. Assuming the character of purchaser, the person so acting neces*351sarily abandons that of agent, and can claim nothing in the latter capacity in his negotiations with his former principal. Such is the undoubted general rule. But the question presents itself, whether there may not be exceptions growing out of the peculiar nature of the agency, or certain special or limited agencies not falling within the reason of the rule, and so not within the rule itself. The reason of the rule is very plain. It is, that the interest of the party as purchaser, being adverse to that of his principal, supposing the agency still to continue, might and most naturally and ordinarily would lead to a violation of his duty as agent. If a case can be presented, however, not within the reason of the rule, as of an agency limited to a time anterior to the purchase, or where the agency may be said to have expired, or the duties to have been performed, before the purchase takes place, to such a case it is presumed the rule would be held inapplicable. If, for example, the principal says to the person whose services he wishes to engage, “ I have a farm which I wish to sell, the price of which is $1,000, and for which, if you will find me a purchaser, I will give you -a commission of five per cent, or $50,” and the person addressed thereupon says, “I will find you a purchaser — I will become the purchaser myself on those terms-; ” if upon the proposition so made and accepted, the sale takes place, it would seem that the agent or broker, although himself appearing in the character of purchaser, would be entitled to his commission. The agency being limited and special, confined to the procuring of a piu-chaser at the price specified, would appear to have ended when a purchaser was produced, and before the sale or transfer was made. Pending the transfer and sale no fiduciary relation or agency would exist, but the principal would be acting for himself and on a footing of perfect equality with the purchaser) notwithstanding such purchaser might previously and fora moment of time have been considered as occupying the position of agent for the seller. Sucha case would not be within the reason of the rule, nor the mischief intended to be obviated by *352it, and therefore the rule would seem to be inapplicable to it. The seller, having deliberately and of his own free will fixed the price of the farm and the commission he would pay in case a purchaser was found, could not with reason be heard to complain that the broker had himself become the purchaser; and his acceptance of the offer under such circumstances would altogether likely be construed as an assent on his part to the change of relation, and to the broker becoming the purchaser, within the meaning of the proposition made for one to be found. In such case the only point of any difficulty or doubt would appear to be one of mere fact, and that, whether the seller intended to accept and did accept the offer as within the terms of his agreement to pay the commission. In the case supposed, there would seem to be not much room for doubt, but others arising under different circumstances might present very great difficulty.
Upon the question now under consideration we find but little or no direct authority in the books. We know of but one case in which it has been raised or discussed. In Tower v. O'Neil, 66 Pa. St., 332, one of two.agents authorized in writing to sell certain real estate within a time for a price fixed by the owner in the writing, and for which he agreed to pay a commission of two per cent, and all that might be obtained over and above the price specified, said to the owner, when applying to have the written article of agreement given up to him, that he (the agent) would take the property at the contract price himself, rather than let the time run out. The offer was not accepted by the owner, and the parties came to a different arrangement, by which the article was surrendered upon payment of a certain compensation by the owner to the agents. In the suit by the agents to recover the full commissions, it was claimed that the proposition so made by one of the plaintiffs, to take the property himself, which he and his coplaintiff were authorized to sell, amounted to or was equivalent to a sale of it under the power. The court below was of the opin*353ion, and so instructed the jury, that the proposition could not be regarded as equivalent to a sale, because the instrument giving the power to sell did not contemplate a sale to the plaintiffs, or either of them — and public policy denied the right of an agent, under such a power, to sell to himself. The case on error turned upon another question, but the court, industriously avoiding a decision of this question of public policy, which it said was the one mainly discussed in the oral and printed argument, thus stated the position of counsel for the plaintiffs with respect to it, and to the instruction which was given and which they insisted was erroneous. “ The plaintiffs contend that, under the stipulation contained in the power of sale, this instruction was erroneous, and that the rule of law which forbids an agent to sell to himself, or several joint agents to sell to one of their own number, has no application to this case. The plaintiffs were authorized to sell the property for seventy thousand dollars, and for their services in making the sale the defendant agreed to pay them á commission of two per cent, and the additional commission of all they might sell the property for above the sum of seventy thousand dollars. As the price which the defendant was to receive for the property was fixed and limited by the stipulations contained in the power of sale, irrespective of the amount for which it might be sold, the plaintiffs insist that, without any violation of the policy of the law, either of them had the right to purchase the property on the same terms they were authorized to sell it to a stranger, and that the offer of one of them to take it on those terms was equivalent to a sale under the power, and entitled them to the commission which the defendant agreed .to allow them. But it seems to us that the question mainly discussed in the oral and printed argument, whether this case comes within the rule of law which forbids an agent to sell to himself, does not properly arise under the evidence.”' There is something in the manner of stating the proposition, and the anxiety manifested by the court not to deny its correctness but *354to decide the case on other grounds, which, amounts to a tacit, and one might almost say, a positive recognition of its correctness. And further on in the same opinion the court say: “It is clear that the offer, under the circumstances in which it was made, cannot be regarded as equivalent to a sale of the property under the power.. It was not so intended, or understood by the parties at the time it was made. There was no tender of the purchase money, nor was anything done by the plaintiffs, or either of them, in pursuance of the offer, to put them in a position to treat it as equivalent to a sale under the power. On the contrary, they voluntarily surrendered the power of sale, and accepted the money tendered by the defendant as a compensation for the services they had rendered. But if the offer to take the property was made in execution of the power of sale, as contended by the plaintiffs, the defendant was under no obligation to accept it; and his refusal of it did not render him liable for the commissions he agreed to pay for selling the property. The relation between the parties, under the power of sale, was that of principal and agent, and it could not be changed to that of vendor and vendee without ike consent of the defendant.” The implication from this language, and, as it seems to us, quite strong and clear, is, that if the defendant in that case had accepted the offer, and if it had appeared that the parties intended or understood at the time that it was a sale under the power, then in the opinion of the court the plaintiffs would have been entitled to their commissions. The acceptance of the offer under such circumstances would have been looked upon as a consent on the part of the defendant to the change of relation from agent to purchaser involved in the offer.
And there are still other authorities which seem to us to favor the same view. The general rule is, that a person cannot be agent for both purchaser and seller, and earn a. compensation from each. The reason of this rule is the same as that for the other, which, in general, forbids the agent or brok*355er from becoming the purchaser. But to this rule an exception arises whenever the reason fails. If the agency or office of the broker is merely to procure an interview between his two constituents or principals, who themselves negotiate and conclude the sale or exchange, the broker is entitled to his customary compensation from each. Not himself negotiating between or for either of the parties, nor in any degree influencing them to make the trade, it is immaterial that each -was ignorant that he was acting for the other, and the broker will be entitled to his commissions from each. Mullen v. Keetzleb, 7 Bush, 253. A broker- whose undertaking merely is to find a purchaser at a price fixed by the seller, or at a price which shall be satisfactory to the seller when he and the purchaser meet, is in reality only a “ middleman,” whose duty is performed when the buyer and seller .are brought together, and as to whom the policy of the law which excludes double compensation has been considered inapplicable. Thus, in Rupp v. Sampson, 16 Gray, 398, it was held that if a middleman brings together a buyer and a seller, each of whom has agreed, without the knowledge of the other, to pay the middleman a commission on any contract which may be made between them, and a contract is made between them, in the making of which the middleman takes no part as agent for either, the conduct of the middleman in concealing from each his agreement with the other is not fraudulent, and is no defense to an action brought by him against either to recover the commission agreed upon-. And in strict harmony with these decisions is the early one by this court in Herman v. Martineau, 1 Wis., 151.
These decisions tend very strongly to sanction the rule, that where the broker merely engages to find a purchaser at such price as may be agreed upon, if he presents himself- as such purchaser, and the seller, with full knowledge of that fact, so receives and en ters into negotiations with him, and a sale is consummated, the broker may recover his commissions. But the proof in such case should be clear, and the knowledge and *356intent of the seller satisfactorily established in the mind of the jury. The testimony of the plaintiff in this case tended to show that the defendants did so understand the transactions, and that such was their intention as well as his own. In this the plaintiff seems to have been corroborated by some other circumstances, and had the question been submitted to the jury, it is possible, or may even be probable, they would have so found. But the question was not submitted to the jury, and for this defect in the instructions we are of opinion a new trial must be ordered. Without a finding by the jury that such was the intention of the parties, defendants as well as plaintiff, the presumption in a case of this kind must, we think, be, that the sale was consummated, not within, but without the agreement to pay the commission. The burden of overcoming this presumption rests upon the plaintiff. It is something like the case of an agent negotiating for both buyer and seller where it is held he cannot have or earn compensation from each, unless by distinct arrangement between all concerned.
The instructions of the court below upon this branch of the case were as follows :
“ The plaintiff claims that the defendants engaged him to sell the property, or find a purchaser therefor, at such a price as they were willing to sell the same, and to allow him a commission of five per cent.
“ Upon this branch of the case you are first to ascertain from the testimony whether the defendants, or either of them, employed the plaintiff to sell the property, and, if they did, what price or commission he, the plaintiff, was to receive for such services if he should effect a sale.
“ If, upon a full and candid review of the testimony, you find for the plaintiff on this proposition, you must next inquire whether the plaintiff did effect a sale of the property in question ; and if you find that the plaintiff did find a purchaser for the property, and a sale was effected to such purchaser, then, as a matter of law, so far as the question of commission is con*357cerned, I consider" that it mates no difference whether the plaintiff became the purchaser of a part of said property or not. If he was employed to find a purchaser, for which he was to have a commission, if he did find a purchaser, he would be entitled to his commission, although he himself became the purchaser.”
If to the words last quoted the court had added the further ones,— “ provided you also find he became the purchaser under the agreement of the defendants to pay the commission, and with a knowledge or understanding to that effect on their part at the time of purchase,” — it is improbable that any exception could have been sustained to the instruction, or that the verdict, if for the plaintiff, could have been disturbed. As the case now stands, however, the judgment must be reversed, and a new trial awarded.
By the Court.— It is so ordered.
