delivered the opinion of the Court:
Various errors are assigned upon this record. The first arises upon the ruling of the circuit court in respect to the jury to which the issues were submitted. Appellants objected to the whole array of jurors, because they had not been drawn by the clerk of the court, as required by the statute, but had been selected by the sheriff, and moved to quash the venire, and which motion was overruled. By agreement of parties, the statement of the clerk as to the manner in which the panel of jurors was obtained, was received. From the clerk’s statement it appears the panel was obtained upon an order of the circuit judge, made the preceding Wednesday, ordering the issuance of a special venire for twenty-four men, and upon that order the clerk issued the writ to the sheriff; and this is all the evidence disclosed by the record.
*340The objection is met by two sufficient answers: First, if it be assumed that the jury was obtained irregularly, a challenge to the array will not be sustained, where it is not also shown that a positive injury has been sustained in consequence of the refusal of the court to quash the panel. (Wilhelm v. The People, 72 Ill. 468, citing Mapes v. The People, 69 id. 523.) There is no pretense, here, of injury to appellants, or that the trial was not fair. What the jury did in this case, as will be seen hereafter, was to return a verdict as directed by the court. The issues were taken from the jury entirely, and they made no independent finding whatever. And second, there is nothing in this record, save the language of the motion itself, that shows, or tends to show, that every requirement of the statute as to the drawing of jurors was not observed. The evidence is, that the panel was obtained upon an order of the judge of the court directing the clerk to issue a special venire to the sheriff for a given number of jurymen. Non constat, the clerk repaired, as by law required, to the office of the county clerk, and there drew the twenty-four names from the proper box, and inserted those names in the venire issued to the sheriff. Presumptively the clerk did his duty, and that presumption appellants should have overcome by proof. The record contains no proof whatever tending to impeach the regularity of the panel or the qualifications of the jurors.
The main controversy, however, arises upon the instruction given by the court, directing a verdict for the defendant. As the case stood at the time the instruction was given, it was entirely competent for the court, and correct practice, to direct a verdict for the defendant, for the reason that there was not before the jury sufficient evidence to support a verdict for the relators. But back of this instruction lay the action of the court in rejecting the evidence offered by the relators. If the offered evidence was competent, and tended to sustain the issues on behalf of the relators, its rejection was erroneous and the instruction improperly given.
*341Under the practice prevailing prior to the present statute relating to mandamus, the alternative writ became the foundation of all subsequent proceedings in the case, answering the same purposes as the declaration in ordinary actions. This being so, it was necessary that the alternative writ should show upon its face a clear right in the relator to the relief demanded. Therein the relator was required to distinctly set forth all the material facts on which he relied, so that the same could be admitted or traversed. (Canal Trustees v. The People, 12 Ill. 248.) The statute referred to, (Starr & Curtis, 1584,) while it has changed the practice, dispensing with the issuance of the alternative writ, and requiring the defendant to answer, plead or demur to the petition, has not modified or dispensed with the common law requirement resting upon the relator, to set forth and show a clear and indubitable right to the relief demanded. In every case, to entitle the relator to relief, it must appear that the defendant is under a legal obligation to do and perform the act required, and every material fact necessary to show such legal duty must be averred in the petition. Hall v. The People ex rel. 57 Ill. 307; The People v. City of Elgin, 66 id. 507; The People ex rel. v. Village of Crotty, 93 id. 180.
The act in relation to roads and bridges, under township organization, approved May 28, 1879, and in force July 1, 1879, (Laws 1879, p. 257,) is broad and comprehensive in its terms and provisions, embracing within its scope the establishment, alteration, construction, repair, maintenance and supervision of roads and bridges within organized towns. The immediate control and supervision of roads and bridges in a town was vested in three commissioners of highways, who were required to meet at a designated time and place, and to organize by choosing one of their number treasurer, and thereafter to fix their own time and place of meeting; and by the 13th section of the act, the commissioners were required to “keep a correct record of their proceedings at all meetings.” Although reference is here made to the particular act named, in prior as also *342in subsequent acts, similar provisions appear and like powers were vested in and duties imposed upon these boards of highway commissioners, and they are now, and were under this particular act, regarded and held to be a' quasi corporation, powerless to act, except together and as a body, (Commissioners of Highways v. Baumgarten, 41 Ill. 254, and McManus v. McDonough, 107 id. 95,) and of which action, as we have seen, under the act of 1879, they were required to “keep a correct record.” It seems clear that the same rules of law are to be applied to this corporate body in respect of its corporate action, and the evidence of such action, as are applied to other municipal corporations, and that the record of its action required by law to be made and kept, becomes the best, and if in existence and capable of being produced, the only evidence thereof.
The 110th section of the act of 1879 provided under what circumstances a moiety of the expense of the construction of a bridge in any town might be borne by the county. To avail of such county aid, and as the basis of any action to that end by the county authorities, it must appear, first, that a necessity existed for the construction or repair of such bridge; second, its construction or repair must be an unreasonable burden on the town; third, the cost must exceed such sum as could be raised in one year by ordinary taxation for bridge purposes in the town; and fourth, that one-half the necessary funds therefor had been provided by the town. These facts are, by the law, made jurisdictional, and without their existence and concurrence the county board was without power to appropriate money from the county treasury for the purpose stated. The determination of these jurisdictional facts is, by the act, left to the commissioners of highways. Acting as, alone; they had the power to act, together and as a board, at a meeting of the board they were to determine that the construction or repair of a bridge‘within their territorial jurisdiction was necessary; that its construction or repair would be an unreasonable burden on the town; that the cost thereof would exceed the sum *343that could have been raised in one year by ordinary taxation for bridge purposes in the town, and that they, by means under their control, had provided for one-half the necessary expense, of which determination they were required by the act to make and keep a record; and this same section of the act (section 110) made it the imperative duty of the county board, whenever the commissioners of highways of a town brought themselves within the provisions of the act, to appropriate, out of the county treasury, one-half the cost of the proposed construction or repair. In the case under consideration, the commissioners of highways of Wood River township sought to avail of the provisions of the act referred to, and if the case made by them petition and proofs was such as to bring them within the law, the writ should have been awarded.
By the averments of relators’ petition a prima facie case was made. Issue being taken thereon, it became necessary for relators to maintain, by competent testimony, the truth of every material averment, taking upon themselves the same burden that rests upon the plaintiff in an ordinary action at law, where the averments of the declaration are put in issue. To meet this requirement, the relators produced, as a witness, the town clerk of Wood River, who was also the clerk of the commissioners of highways for the year 1882, who testified that the commissioners held meetings on April 19, August 19 and September 2, 1882; and on his being asked if the commissioners of highways of the town did not determine to build a bridge, objection-was interposed by'the defendants, and sustained by the court. This ruling of the circuit court was unquestionably correct. As we have before stated, the determination by the commissioners of highways that a necessity existed for the construction or repair of a bridge, as a basis for an application to the county board for county aid under the statute, was an exercise of a corporate power vested in the commissioners of highways, which could only be at a meeting of the commissioners, and be shown by the record *344required by the law to be made and kept. Before the county board could be legally moved in the matter, or any legal duty be cast upon them, the commissioners must have determined that such necessity existed, and have preserved the evidence of that fact in their record. In the proceeding, then, before the circuit court, the corporation (the commissioners of highways) could only speak by their record, unaided by parol testimony.
The principles announced seem to be well supported by authority. Where the law requires records to be kept, they are the only lawful evidence of the action to which they refer, and such record can not be contradicted or supplemented by parol. The whole policy of the law would be defeated if they could rest partly in writing and partly in parol. Stevenson v. Bay City, 26 Mich. 44; Hall v. The People, 21 id. 456; Morrison v. City of Lawrence, 98 Mass. 219; Hanneman v. Fire District, 37 Vt. 40; Mayhew v. District of Gay Head, 13 Allen, 129. So where county commissioners and township trustees were required by law to keep a true record of their proceedings, it was held that they could “only speak by their record” when legally assembled. (Commissioners of Fayette County v. Chitwood, 8 Ind. 504.) And where school districts are required by law to keep an account of their proceedings by a sworn clerk, such proceedings can only be proved by the record. Offered parol proof was rejected. (Jordan v. School District, 38 Maine, 164.) And in respect of the county court, in counties not under township organization, constituting, in such counties, the county board having the management and control of the fiscal affairs of the county, it was held that in matters of allowance or rejection of claims against the county, the records of the court are the only admissible evidence of their official acts. McHaney v. Marion County, 77 Ill. 488.
The relators read in evidence the record of the commissioners of highways, of August 19, 1882, as follows: “The amount of taxes was fixed at forty (40) cents for bridges, and twenty (20) cents for roads. For making and repairing bridges, *345$6000.40; for other purposes, $2100.01,—total, $8100.41. Moved to petition county for aid in building bridge over Wood river,—carried;” and offered, in that connection, to prove by their clerk, that at the meeting on August 19 it was determined to build the particular bridge; that it'was necessary it should be built; that its construction would be an unreasonable burden on the township; that a tax was levied by the commissioners for the purpose of providing one-half the estimated cost thereof; that the estimated cost was $5000, and that the memorandum on the records was the result of the determination and action of the commissioners. The court sustained an objection to the offered testimony. The offered testimony was in the highest sense material, and had it been embodied in the record of the commissioners, it would have tended to establish every material averment of the petition. But the imperfect record of the determination and action of the commissioners could not thus be cured and aided by parol. Considerations of the gravest character require us to hold, that where the law has required a record to be kept of corporate action by any of the agencies of the State, the record alone can he resorted to to establish such action, in all collateral proceedings.
Further offers of proof were made by relators, in respect to the estimate by the. commissioners of the sum needed for making and repairing bridges for the year 1882, including one-half the cost of this new bridge; that an estimate of the cost of this bridge was procured from the county surveyor, (of which, however, no record was made,) of the rate per cent of the levy for bridge purposes, of the amount collected and turned over to the commissioners, and what part of it was for this new bridge,—to all of which objection was sustained. As will be seen, every material fact offered to be proved by parol should have appeared in the record of the action of the commissioners, or was capable of proof by the public records of the county, and the ruling of the circuit court was correct.
*346Relators did read in evidence their petition to the county board asking for county aid, and also the record of the action of the county board thereon, from which it appeared an allowance from the county treasury was made of $1000. The fact that the county board was petitioned for county aid, might, no doubt, be shown by the petition itself, but such petition, though made and signed by the commissioners, can not be regarded as proof of the facts recited therein, so as to supply the absence or take the place of the record of the action of the commissioners, required by the law to be kept. But the petition itself shows upon its face that at least one of the conditions precedent, provision made by the town for one-half of the cost of the proposed bridge,—did not exist. One-half the cost was $2500, and only $2200 of the amount raised was, it appears,' available for this bridge. When, therefore, the court was asked to give the instruction directing a verdict for the defendant, it is manifest there was no evidence authorizing a verdict for the petitioner. The most that can be said of the record of the commissioners, made at their meeting August 19, is, that it tended to show that the commissioners had levied a tax of forty cents for bridge purposes and twenty cents for roads, the sum raised thereby, and a proposition to “petition the county for aid in building bridge over Wood river.” None of the facts necessary to authorize them to demand aid from the county are shown thereby to have been found or determined by the commissioners. It was, however, shown that the county board appropriated $1000 for that purpose, and it is contended that the county is estopped thereby to question the validity and sufficiency of the action of said commissioners of highways. Unless the county board, by its action in making the appropriation of $1000 in a case where, under the law, they were not required or authorized to make any appropriation whatever, is estopped from afterwards refusing to make a further unlawful appropriation of $1500, there was no competent evidence before the jury proving or tending to prove the several material averments of relators’ petition.
*347That the action of the county board in making the 01000 appropriation was wholly unauthorized by the statute under consideration, because of the non-existence of one or more of the jurisdictional facts, seems clear; and while it is true that the county board is vested with the control and management of the fiscal affairs of the county, its powers are such, only, as are given it by the law. Within the scope of the powers granted or necessarily implied, it may act. But we can not lend our sanction to the doctrine that an illegal and unauthorized exercise of power by a municipal corporation can he made the basis for compelling a repetition of such illegal act. There is no pretense that this appropriation was made under section 58, chapter 34, of the Revised Statutes, (Starr & Curtis, 662); but if it was, it would form no basis -for the application of the doctrine of estoppel. The doctrine here announced is not at all inconsistent with former rulings of this court, that in a proper case the doctrine of estoppel may be invoked against municipal corporations. This case presents none of the elements necessary to an application of the doctrine of estoppel. ’
The court properly gave the instruction complained of. The relators had wholly failed to support, by competent testimony, the jurisdictional facts necessary to the maintenance of their petition. There were no controverted questions of fact to be passed upon and settled by the jury, and no testimony upon which a verdict for the relators could have rested, had one been returned. In such case, the practice is well settled that the court.may direct a verdict for the defendant.
The modification, by the Appellate Court, of the judgment of the circuit court in respect to costs, was clearly correct. The proceeding was begun and conducted by appellants, not as individuals, but in their official character of commissioners of highways, and appellee’s costs, for which it was entitled to judgment, were properly made a charge upon relators in the capacity in which they sued.
Perceiving no error in the judgment of the Appellate Court, it is affirmed.
Judgment affirmed.
