By the Court,

Dixoet, C. J.

These tvro cases depend upon the same state of facts, and involve the same questions of law.' Both are actions brought to restrain the collection of certain taxes in the towns of Burlington and Rochester, in the county of Racine, and to test the validity of certain bonds purporting to have been issued by the boards of supervisors of those towns, pursuant to chap. 138 of the Private Laws of 1856, to aid in the construction of the Fox River Yalley Railroad. The taxes were levied for the purpose of paying the interest on the bonds. The validity of the bonds and the power to levy the taxes are denied upon the ground that the act in pursuance of which the bonds are said to have been issued, was not published until after they were executed and put in circulation, and this is the only question to be decided. By the 5th section, the supervisors possessed no power to issue the bonds, until a majority of the legal voters of the town, voting on the question, at an election to be called for that purpose, should vote in favor of the same. It is conceded that the act is a general law, within the decision of this court in the cases of The State vs. Lean, 9 Wis., 279, and Clark vs. Janesville, 10 Wis., 136, and that as such it could not, under the constitution, take effect until published. It is likewise conceded that it was not published until after the elections were held and the bonds issued. It appears, also, that the bonds have gone into the hands of third parties, for value, without actual notice of defects, except such as the law implies, and that in the years 1857 and 1858 the supervisors appointed commis- *438> sioners to vote upon tbe stock received, in payment for tbe . bonds.

? Upon these facts it is insisted on tbe part of tbe appellants :

1. That tbe respondents are estopped by tbe recitals in tbe bonds, from asserting that there was no law in force at tbe time they were issued, authorizing tbe same; and

2. That if they can impeach tbe recitals, their acts in relation to tbe bonds are such that they ought not now to be permitted to deny their legality.

Tbe first point is obviously bad. Tbe appellants do not propose to deny tbe recitals of tbe bonds, conceding tbe instruments to be such, but to show that they are not bonds, and therefore that there are no recitals by which an estoppel can be created. They propose to go back of tbe objection taken by tbe respondents, and to show that tbe foundation upon which it must rest, does not exist. Tbe supervisors could not issue tbe bonds without previous legislative authority, and if such authority was wanting, their action was void. To claim, therefore, that their recitals that they bad such authority are conclusive as against a proposition to show that they bad not, is equivalent to claiming that they could act and could bind the towns even though they possessed no such power, which is absurd. It is to make tbe question of authority wholly immaterial, and to say that the unauthorized action of the board is as obligatory and effectual as that which was authorized. Tbe rule that a party is estopped from disputing a fact which be has solemnly admitted by deed, assumes the existence and validity of the deed, but it does not preclude him from showing that be never made it. So here the recitals that the bonds were issued in pursuance of a law of tbe state of Wisconsin, do not prevent our inquiring whether there was such a law, for if there was not, then they are no bonds, and the recitals are of no effect whatever. It being conceded that within the former decisions of this court, there was no such law, it follows that the bonds must fall for want of power to execute them, unless they have been ratified since the law took effect, or unless the subsequent conduct of the respondents has been *439such as to estop them from denying tbeir validity. And we do not think they can be sustained on either of grounds.

In the first place it is to be observed that the power of the supervisors to take any step, or to consummate anything in the way of issuing the bonds, depended upon a previous vote of a majority of the voters of the town, in favor thereof. Unless authorized by the voters, they derived no authority from the act to issue them. They were made the agents of the voters, who were the real parties in interest, for the purpose of making an agreement with the railroad company for stock, and paying for the same in the bonds of the town; and by the express terms of the act, they could do so only upon obtaining the assent of the voters in the manner therein required. The voters or inhabitants of the town being the contracting party upon one side, and the railroad company upon the other, and the supervisors, the mere agents of the former, having no power to act without their assent, it follows that, if they did so act, that action was nugatory and void. But as the assent of the voters could only be obtained upon the authority of law, if there was no law then there was no authority, and consequently no assent ; and the supposed election was wholly futile and useless. So that if the bonds had been issued after the law took effect, yet as the election was had before, there would still be this reason for holding them inoperative. Now as the voters were the principals, and the supervisors the agents, it would seem obvious that any ratification of the previous unauthorized acts of the latter, after the power to do so became complete, must come from the voters and not from the supervisors. For it would be manifestly contrary to reason to say that the agent himself might ratify and confirm his own unauthorized act. This proposition is so self-evident that argument upon it is unnecessary, if not impossible. Hence it is that the acts are wholly inefficacious to give validity to the bonds, except as they were directed or assented to by a majority of the voters after they had acquired the power to do so by the due publication of the law. The only acts, either on the part of the supervisors or the voters, which are claimed to have any *440tendency to show a ratification, are the appointments of coni-missioners in tbe years 1857 and 1858. These appointments were made by the supervisors alone, and it is not pre^ended that the voters had or took any part in making them. They were matters over which the voters had no control, and to which their assent cannot be presumed. There has therefore been no ratification of the bonds, and it remains to be determined whether the voters have otherwise concluded themselves from denying their validity.

On the part of the respondents, it is strenuously insisted that they have. It is urged that, by neglecting to interfere and assert their legal rights, and restrain the issuing of the bonds, at a time when they might have done so, so as to have saved innocent third parties, they ought now to be estopped from denying their legality, or the authority of the supervisors to issue them. It is said that their failure to act and to protest, when the opportunity was afforded them, so as to protect not only themselves but the public, is a recognition of that authority, and that they should not now be permitted, as against innocent third persons, to escape from the fulfillment of obligations which have thus tacitly received their sanction. There can be no doubt of the general force and correctness of these principles, and that under ordinary circumstances such conduct would constitute a valid estoppel in pais. The authorities cited fully demonstrate that they are applicable to cases like the present, where no other principle interferes to prevent their operation. As applied to the cases cited, we yield our fullest assent to them. But they are inapplicable here, for the reason that the nature of the defect in the original execution and issue of the bonds, is such, that there can in law be no innocent holders of them. The defect was in matter of law with a knowledge of which every person is chargeable. It was in matter of law unmixed with any particular matter of fact. It was that there was no law authorizing them, and of this all parties were bound to take notice, as well the purchasers as the seller of the bonds. They .were presumed to know the provisions of the constitution, as well as the time when the statute became operative under them. In this respect *441neither party possessed advantages superior to those of the other. It was information which was alike open to all, of which all were equally bound to avail themselves for the purpose of forming an opinion upon their legal rights. This is an old and well settled rule of the law, its maxim being that ignorance of it will not excuse; and although it may operate with some severity in the case before us, it cannot be disregarded. By taking notice of the time when the law took effect, and examining the date of their issue, it appears upon the face of every bond that they were executed without legal authority. No stronger case of the rule that ignorance of the law will not excuse or protect, could be put. So long, therefore, as the bonds were void upon their face, and within the actual or presumed knowledge of all the world, it certainly cannot be contended that the voters were guilty of any laches or negligence in not restraining their sale or circulation. It would be idle to say that they must commence a series of law suits for the purpose of apprising third persons of that which they already knew; and it was clearly time enough for them to resist or deny, when the validity of the bonds was seriously asserted and an effort made to collect them, which, for aught they knew or might reasonably presume, would never be done. No element of actual fraud or bad faith is introduced or relied upon. They are cases of mutual ignorance and mistake of the law, against which the holders, though otherwise innocent, cannot be relieved.

The cases of The State ex rel. Ganett vs. Van Horne, 7 Ohio St. R., 327, and The State ex rel. Smead vs. The Trustees of Union Township, 8 id., 394, are distinguishable from these in this, that there the mistake consisted in a matter of fact of a private or particular nature, of which the public or third persons were not bound to take notice, but which was known to the tax payers of the township, while here it consists in a matter of law which all are presumed to know, or if it may in any sense be considered matter of fact, that is, the time when a general law takes effect, then of such matter of fact as every person must know. The objections there were, that the lines of the railroads were not actually established and located through the townships before the elections were held. *442The court says, admitting this to have been necessary to au thorize the elections, that it was too late for the tax payers to deny their obligations, after permitting the trustees to issue the bonds, and after paying the interest for several years without protest or interference. And so we think The general authority of the trustees to call the elections and issue the bonds after a vote to that effect, was unquestioned. The objection was to a matter of fact, which was private in its character, and peculiarly within the knowledge of the tax-payers. It was one to which the purchasers of the bonds were in no way privy, and of which they were not bound, át their peril, to take notice. It was at most a mere irregularity in the exercise of a valid power, and not an attempt to act without any legal authority whatever. And such the court evidently regarded it; for in the last named case they say, “ that the township, while retaining the price and proceeds of the bonds, proposes to set up as a defense to their payment, that the township had not in fact proceeded in all respects strictly in conformity to the statute in issuing said bonds, and that, therefore, they are void.” In this respect, therefore, these cases fell fully within the doctrines of Commissioners of Knox County vs. Aspinwall, 21 Howard’s R., 534, and the other cases cited by the appellant’s counsel, but they furnish no guide for the determination of the present.

The judgment of the circuit court must be affirmed.
