Alvey, J.,
delivered the opinion of the Court.
This is an action brought by the appellants against the appellees, for an alleged balance due on contract for extra work on the new City Hall in the City of Baltimore.
The appellants were the contractors for supplying the marble and doing the marble work'on the new City Hall; and the marble was furnished and the work all done in accordance with the requirements of the contract. The work and materials were all accepted by the appellees, through their Building Committee, and the contract price, amounting to a sum between $900,000 and $1,000,000, was paid, according to the terms of the contract, excepting only the price for the extra work which had been done.
In the specifications for the building, in reference to which the proposals of - the appellants for the work were made, and which proposals are referred to and made part of the contract between the parties, this provision occurs: “All extra work, additions or omissions, not referred to in the following lists, shall be valued by the architect, with reference and in proportion to the contract price.’'
*93It is admitted that after all the work was done, the extra work, embraced by the provision just cited, was measured by Mr. Frederick, the regular architect of the building, and was valued by him at the sum of 046,852.29. This valuation, however, was not satisfactory to the Building Committee, and they refused to certify to its correctness, or to give an order for the amount thus ascertained, without which the money could not be obtained from the city treasury. In order to adjust this question in an amicable way as between the Building Committee and the appellants, it was agreed, (Mr. Adams, a member, acting on behalf of the Building Committee and with their approval, and the appellants acting for themselves,) “that the list of items hereto annexed, of work not specified in the contract, but done by the said M. A. Sisson & Co., upon the City Hall Building, shall be referred to Mr. A. B. Mullett, with authority to determine according to the rule laid down in said contract, what prices for the said several items of work are justly due and payable by the said Building Committee to said M. A. Sisson & Co.: and the decision of the said A. B. Mullett shall be final and binding on both parties.” Mr. Mullett is an experienced architect of the City of Washington, and it would appear that both parties were entirely willing to abide his decision, as the question between them depended alone upon the proper measurement of the work, and the ascertainment of the prices to be charged therefor, according to a rule previously agreed upon by the parties themselves. The matter of difference having been thus referred, it is admitted that the referee, on the 19th of December, 1873, made his award, allowing to the appellants the sum of $33,471.25, for the same extra work for which Mr. Frederick had allowed the sum of $46,852.29 ; being a reduction of $13,381.04.
Having thus adjusted the question in regard to the extra work, there was still another question of difference between *94the appellants and the Building Committee, and that was as to who should pay the cost of a railway track, laid by the Northern Central Railway Company, under the authority of an ordinance of the city, by which stone and other material were taken to the building whilst in progress of erection. It was insisted by the Building Committee that theprse of this way inured exclusively to the benefit of the appellants, as they brought all their material over this track, and which they were bound to deliver at the building, and that the city was not bound to furnish facility for the transportation and delivery of such material. And while it is not denied that the railway was so used by the appellants, they did deny for a time in a very positive manner that they were bound to pay for it. They insisted that the city authorized the making of the track of its own motion, and that there was no obligation upon them to pay the cost. This question of difference, however, was subsequently agreed between the parties; and it is admitted, that on the 9th of January, 1814, the Building Committee paid the appellants, by an order drawn on the Comptroller of the city, the sum of $32,040.96, which was all the appellants were entitled to receive for the extra work and materials furnished, including the ten per cent, retained under the contract, on the basis of the Mullett award, less the sum of $2506.20, retained to reimburse the city the cost of the railway track. This latter amount was retained by the agreement of the appellants, and the sum of $32,040.96, was received by them in full settlement of all claim under the contract for marble work, and a receipt was given to that effect. The appellants proved at the trial below that they agreed to these terms of settlement, first, because they supposed at the time, the award in regard to the extra work to be binding upon them, and secondly, that they could not get the money thus awarded them, without resort to litigation, except upon the condition of allowing for the cost of the railway; and that they *95were “willing to settle the dispute by accepting the conditions to get rid of the whole matter.”
This being the state of the case, there are two questions presented: 1. Whether the appellants are concluded by their acts in reference to the award of Mullett, the referee, upon the claim for the extra work; and, 2. Whether they are bound by their agreement that the cost of the railway track should be retained out of the money found to be due them by the award. The Court below determined both these questions against the appellants, and consequently rejected all their prayers, and the judgment was for the appellees.
1. The theory upon which the action is sought to be maintained in respect to the extra work is, that the reference and award were not binding upon the appellants; that they were not binding upon the appellees, because the submission or reference was not made by competent authority; and that being so, there was no mutuality in the agreement of reference, and consequently the award was simply void, and the amount ascertained by Frederick remained the amount to which the appellants were entitled. But, according to our apprehension, the case does not depend upon the abstract question, whether the appellees were bound by the submission, nor whether the appellants were bound by the award before it was acted on and made the basis of settlement, and the money received under it; but the real question is, whether the Building Committee had the right to raise the question of difference with the appellants, and if so, whether, after resorting to the amicable means of a reference, in order to settle the question, and the appellants have acquiesced in the result of that reference, and received the money ascertained to be due by the award, they can now repudiate it, and fall back upon the claim for the amount ascertained by Mr. Frederick before the reference was made P The law always favors compromises and amicable adjustments of *96disputes, rather than compel parties to resort to litigation and it would he strange if, in the absence of clear evidence of fraud or mistake, the parties were not hound and con-eluded after what has taken place in respect to this award.
The Building Committee represented the city under ordinance No. 78, approved 5th August, 1868, providing for the erection of the New City Hall; and they were clothed with large supervisory powers, as well in regard to the making of contracts as to their faithful execution; and no money could he paid to any contractor for work on the building, unless he produced an order from this committee certifying that it was justly due. By the 6th section of the ordinance, it was expressly provided that the Register, of the city should pay the different contractors such amounts as might become due on their contracts, upon the production of an order for the same, duly signed by the Superintendent and a majority of the Building Committee, stating that the money was legally and justly due, and certified to as being correct by the City Comptroller. If, upon the measurement and valuation of the extra work by the regular architect, the Building Committee had reason to believe that it was not correct; that it was excessive, and largely to the prejudice of the city, their plain duty required them to withhold their approval of such measurement and valuation, and to refuse the order stating that the amount as ascertained was legally and justly due. How then was the matter to be dealt with ? What mode better than, by mutual consent, to invoke the aid of some competent person to revise the measurements and calculations of the regular architect, as a means to a just and satisfactory settlement of the question ? This was done by the reference, and it was not only voluntarily done, but the appellants, and also the regular architect, Mr. Frederick, attended the referee and furnished him the necessary data to enable him to make his award. The *97award was made, accompanied with, all the measurements and calculations upon which the conclusion was based; and there has not been the slightest attempt to point out error in the work of the referee. The award was fully acquiesced in by the parties to the reference, and the money has been paid to the appellants on the faith of it, which they were willing and actually agreed to accept in full settlement of their claim under the original contract. After such dealing, it does not lie with either party to make question of the legality of what has been done. If the award had been for the full amount as ascertained by the regular architect, or even more, and it had been accepted and acted on as the award in this case has been, it is clear the city could not maintain an action to recover back the money paid under it; and if the city would be concluded, why should not the appellants in this case be equally concluded ? We think it clear that both parties are concluded with respect to the amount ascertained to be due by the award.
2. Then, as to the cost of the railroad track retained by the Building Committee, with the consent of the appellants, from the amount ascertained to be due for the extra work. As we have already stated, it is not disputed that the appellants used the road for the delivery of their material, and that the city was under no obligation to the contractors to make or pay for the road. It authorized the making of the road, and paid the Northern Central Railroad Company the cost of construction; but it insisted that as the road inured to the benefit of the appellants they should pay for it. This was certainly a proper question for adjustment between the parties concerned; and, as was said by the Supreme Court of the United States, in the case of Sweeny vs. U. S., 17 Wall., 75, 78, “Parties may adjust their own disputes, and when they do so voluntarily and understandingly, no appeal lies to the Courts to review their mutual decision.” There is no suggestion here that *98the appellants did not understand all the facts under which they were acting at the time of the settlement; and it was to avoid litigation that they agreed to settle the dispute in the manner they did. It is said that the appellants were coerced to mate the settlement, inasmuch as they could not get the money due them without agreeing to be charged with the cost of the road tract. However that may be, there is nothing in the case that brings it within the legal definition of duress. Repeating again the language of the Supreme Court, used in the case of U. S. vs. Childs & Co., 12 Wall., 244, “If the principle contended for here he sound, no party can safely pay by way of compromise any sum less than what is claimed of him, for the compromise will be void as-obtained by duress. The common and generally praiseworthy procedure by which business men every day sacrifice part of claims which they believe to be just to secure payment of the remainder would always he duress, and the compromise void.” If the appellants had paid the money for cost of the road track, instead of agreeing that it should he deducted from the amount of their claim against the city, by which a final settlement was procured, there could be no color of claim for recovering it back. How does-this case differ ? The money was in effect paid the city, when the appellants agreed to pay the cost of the road track, .and that the amount should be deducted from their claim for extra work, and that they would receive the balance in full settlement. To such a case the language of Gibbs, J., in Brisbane vs. Dacres, 5 Taunt., 151, which has been adopted both by this Court and the Supreme Court of the United States, fully applies. He said: “We must take this payment to have been made under a demand of right, and I think, that where a man demands money of another, as matter of right, and that other, with a full knowledge of the facts upon which the demand is founded, has paid a sum, he can never recover back the sum he has so volun*99tarily paid. It may be, that upon a further view he may form a different opinion of the law, and it may be, his subsequent opinion may be the correct one. If we were to hold otherwise, many inconveniences may arise; there are many doubtful questions of law; and where they arise, the party has an option, either to litigate the question, or to submit to the demand, and pay the money. I think, that by submitting to the demand, he that pays the money, gives it to the person to whom he pays it, and makes it his, and closes the transaction between them.” See Mayor, &c., of Balto. vs. Lefferman, 4 Gill, 431, and Elliott vs. Swartout, 10 Pet., 154. See also, the case of Lester vs. Mayor, &c., of Balto., 29 Md., 415.
(Decided 25th March, 1879.)
In view of these well settled principles of the law, we think the Court below was entirely right in rejecting the several prayers offered by the appellants, and in entering judgment for the appellees, and that judgment will be affirmed.
Judgment affirmed.
