Opinion of the Court. defectively executed a suit could not be maintained thereon, and that the holder was entitled to recover the money paid, with interest thereon from the time the obligation of the city to pay was denied. In Read v. Plattsmouth the bonds were issued by a city for the purpose of raising money wherewith to construct a high school building within her limits. The bonds were sold and the proceeds applied to that purpose. The legislature subsequently legalized the proceedings of the city in the premises, but this act of the legislature was passed after the constitution of the State went into effect, declaring that the "legislature shall pass no special act conferring corporate powers," and that "no bill shall contain more than one subject, which shall be clearly expressed in its title." A purchaser of the bonds for value without notice of any infirmity in their issue brought suit to recover the amount of the coupons then due and unpaid. It was held that as, by force of the transaction, the city was bound to refund the moneys paid it in consideration of its void bonds, and as the act by confirming them merely recognizes the existence of that obligation and provides a medium for enforcing it according to the original intention of the parties, no new corporate powers were thereby conferred. In this case, as in Louisiana v. Wood, the city got the full pecuniary consideration for the bonds, and applied the money to the very purpose for which they were issued; and upon well-settled principles, if the securities given for the money so obtained proved invalid or defective for any reason, there was a clear legal, as well as moral, obligation to refund the money which had been so advanced to and received by the city. The circumstances and conditions which gave the holders of the bonds an equitable right in those cases to recover from the municipality the money which the bonds represented, do not exist in the case under consideration, where the county received no part of the proceeds of the bonds, and no direct money benefit, but merely derived an incidental advantage arising from the construction of the railroad, upon which advantage it would be impossible for the court to place a pecuniary estimate, or to say that it would be equal to such Opinion of the Court. portion of the bonds in question as the county could lawfully have issued. Moreover, by the provisions of the constitution of the State of Nebraska, and by the express terms of the proposition submitted to the vote of the people of Dixon County, the bonds in question were issued as a donation to the railroad company, and, being intended as a donation, it cannot properly be said that the purchasers of these bonds from the railroad company paid any consideration therefor to the county so as to raise any equity as against it, for the amount represented by the bonds, or any part thereof. Any equitable demand which might under the circumstances have existed against the county, on the theory of consideration received, was in favor of the railroad company which constructed the railroad, and thereby conferred all the incidental benefits which the county derived from the transaction. If any equitable claim arises in favor of the holders of the bonds it must be against the railroad company, from whom the bonds were purchased, and by whom their payment was guaranteed, as that company was the recipient of the legal consideration realized upon the negotiation of the bonds. Again, the constitution of the State having prescribed the amount which the county might donate to a railroad company, that provision operated as an absolute limitation upon the power of the county to exceed that amount, and it is well settled that no recitals in the bonds, or endorsed thereon, could estop the county from setting up their invalidity, based upon a want of constitutional authority to issue the same. Recitals in bonds. issued under legislative authority may estop the municipality from disputing their authority as against a bona fide holder for value, but when the municipal bonds are issued in violation of a constitutional provision, no such estoppel can arise by reason of any recitals contained in the bonds. Lake County v. Rollins, 130 U. S. 662; Lake County v. Graham, 130 U. S. 674; Sutliff v. Lake County Commissioners, 147 U. S. 230. But aside from this view of the subject the bill proceeds upon the false assumption that the bonds in question were partly valid and partly void, and that the case is brought Opinion of the Court. within the principle announced in Daviess County v. Dickin son, 117 U. S. 657. In that case, under authority conferred by statute, the county voted a subscription of $250,000 to a railroad company, which was made, and, by order of the county court, bonds of the county to that amount were ordered to be sold and disposed of by a committee, for the purpose of paying such subscription. The officers of the county, without authority, executed and issued bonds in the amount of $300,000. The bonds, as they were delivered, were separately numbered and entered upon the county register. The court held that the power to issue bonds was limited to $250,000, and that the bonds issued in excess of that amount were unlawful and void. It was further held that bonds to the amount authorized, which were first issued and delivered, were valid and entitled to payment. In that case there was a clear and well-defined line between the legal and illegal issues, which enabled the court to declare invalid such of the bonds as exceeded the amount authorized, and to hold that the illegal excess did not vitiate the bonds which were authorized and legally issued. There was no scaling of the entire issue in that case so as to bring it within the limits of the county's authority. The $250,000, which the court pronounced valid, had been expressly authorized by the county, and the bonds for that amount were readily separated from the $50,000 excess which had not been authorized. It did not, therefore, involve any investigation on the part of the court to ascertain what the county could lawfully issue, but was merely the identification of the bonds which it intended to issue. Again, the amount of the bonds issued was not based upon the assessed valuation of the property of the county, but was limited to the amount which the people of the county, by an election duly held, had determined should be issued. There is a radical difference in these respects between that case and the one under consideration. What the county authorized and carried into execution in the present case, both by the vote and by the donation, was one entire transaction, and if it should be so reformed as to curtail the entire issue of bonds to such an amount as was within the constitutional limits of the county to donate, it Opinion of the Court. would be something different from that which was voted by the county, and carried into effect by the issue of the bonds. This would involve the making of a different donation from what the county voted and intended to make to the railroad company. It is urged that the vote and the issue of the bonds constituted a contract between the railroad company and the county, and that the bonds issued in pursuance thereof should be scaled, as sought by the bill, to bring the contract within the authority of the county; that as the county intended to make a valid donation, such reduction of the amount of the issue, which the complainants offer to make, should be sanctioned by the court, and the residue declared valid. But the difficulty in the way of this suggestion is that, treating the transaction as a contract, it is not within the power of a court of equity to change its terms and provisions. Besides, it is not shown that the county would have voted a different amount from what was issued, or that it intended to issue a less amount. It is too well settled to need citation of authorities that a court of equity, in the absence of fraud, accident or mistake, cannot change the terms of a contract. Again, if a right to the equitable relief sought by the complainants could be worked out on the theory of a contract between the county and the railroad company, it would be necessary to establish that such contract actually existed and was valid. In the present case, however, the county had no authority to vote the donation. In Reineman v. Covington, Columbus & Black Hills Railroad, 7 Nebraska, 310, where an excessive issue of bonds had been voted by the county in aid of internal improvements, it was held by the Supreme Court of Nebraska that the vote was simply a void act, and conferred no authority on the county officials to issue the bonds of the county, either to the amount voted or for any amount. It was urged in that case, as in this, that even if it should be held that the proposition submitted to the electors was in excess of the amount authorized to be voted, still to the extent that the county could have lawfully voted and issued such bonds, they should be treated as constituting a contract between the county Opinion of the Court. and the railroad company, and to that extent he upheld. The Supreme Court of the State declined to accede to this view of the subject, and ruled that "the proposition submitted to the electors was an entirety and indivisible. It exceeded the statutory limit, and was therefore wholly unauthorized. The election was simply a void act, conferring no authority whatever upon the county commissioners to issue bonds of the county in any amount whatever." Several state decisions have been cited in support of the bill. Johnson v. County of Stark, 24 Illinois, 75; City of Quincy v. Warfield, 25 Illinois, 317; Briscoe v. Allison, 43 Illinois, 291; State v. Allen, 43 Illinois, 456; Stockdale v. Wayland School District, 47 Michigan, 226. But they mostly relate to taxes imposed beyond authority and stand upon a different doctrine from that involved in the present case. We do not, however, deem it necessary to review them, for if they can be construed to support a bill like the one under consideration, we think they are not founded upon correct principles, and are not in harmony with the decisions of this court. In Buchanan v. Litchfield, 102 U. S. 278, bonds were issued by the city of Litchfield under authority of a statute of Illinois and an ordinance of the city, for the construction of a system of water works for the use of the municipality. Neither the statute nor the ordinance contained any reference to the provisions of the constitution prohibiting any county, city, township, or school district from becoming indebted in any manner, or for any purpose, to an amount, including existing indebtedness, in the aggregate exceeding five per cent of the taxable property therein. The ordinance of the city made no reference to or mention of the indebtedness of the city, although at that time it exceeded the constitutional limit. A bona fide holder of the bonds brought suit upon the unpaid coupons thereto attached, and it was held that they were void and could not be recovered. In this case the city was directly benefited by the issue of the bonds, which were negotiated for the sole purpose of erecting a system of public works. The holders of the bonds thereafter sought relief by a bill in equity against the city of Litchfield to enforce the payment |
