BROWN, C.
The plaintiff sues for taxes charged ' by the city of Carterville, in Jasper county, a city of the fourth class, on the northeast quarter of the southeast quarter of section 17 in township 28 of range 32 in said county, and alleged to be in said city, as shown by the following tabulated statement:
The answer, after a general denial, pleaded facts relating to the situation and condition of the land tending to show that it ougiit not to be subjected to urban burdens, and stated “that the pretended ordinance purporting to extend the corporate limits of said city so as to include the defendant’s land was and is unreasonable, unjust and oppressive, . . . and that *497any and all acts whatever purporting or undertaking to include the said land within the corporate limits of said city of Carterville were and are unreasonable and void. ’ ’ It further pleaded that the same issue was adjudicated in a suit for taxes for previous years, in the Jasper County Circuit Court, wherein the State at the relation of one Al. Pease, collector of said city, was the plaintiff, and this defendant was the defendant, in which there was a judgment upon the same issue for the defendant.
The plaintiff introduced his tax bill, corresponding with the foregoing tabulated statement, and an entry from the records of the Jasper County Court, as of April 16, 1877, as follows:
“In the Matter of Incorporation of Carterville:
“ Whereas, more than two-thirds of the inhabitants of the territory hereinafter named have petitioned the court setting forth the metes and bounds of their village and commons as follows:
“ Beginning at the northeast corner of section No. seventeen (17), township twenty-eight (28), range thirty-two (32), running thence west three-fourths of one mile, thence south one mile, thence east three-fourths of one mile, thence one mile north to place of beginning. The platted town of Carterville being situated within the described bounds, and praying that the territory as above described may be incorporated under the name and style of the town of Carterville and a board of- trustees appointed for the preservation and regulation of any commons appertaining to said town. And having asked that for the first trustees of said town that W. A. Daugherty, J. Alexander Wilson, A. N. Reynolds, J. O. Rose and Joseph W. Manlove be appointed.
“It appearing to the satisfaction of the court that the prayer of the petitioners is reasonable.
*498“It is ordered by the court that the territory above described be and the same is hereby incorporated under the name and style of the town of Carterville and W. A. Daugherty, J. Alexander Wilson, A. N. McReynolds, J. O. Rose, Joseph Manlove be and are hereby appointed trustees of said town.”
The defendant introduced the “Land Tax Book” of the county for taxes of 1906 and 1907 and the “'Land List” of the assessment for the same taxes. The valuation for each of those years as shown on these books is as follows:
The year 1906, total valuation by assessor $2000; total valuation as adjusted by the board of equalization, $6000. 1907, total valuation by assessor $12,000; total valuation as adjusted by the board of equalization, $15,000. The State and county taxes were charged on those valuations. The tax books of Carterville for the same years were in evidence, and showed a valuation upon this land for each of said years of $80,000. A certificate was attached to the city tax book for 1906 the body of which is as follows:
“I, Lon L. Ashcraft, clerk of the county court, and secretary of the board of equalization and appeals within and for State and county aforesaid, do hereby certify, that the within and foregoing contains a fair, true and correct copy, in red ink, of all changes in real and personal property assessments within the city limits of the city of Carterville for the year 1906, as adjusted by the county board-of equalization and appeals, and on file in my said office.”
A substantially similar certificate was attached to the city tax book for 1907.
The record in the Pease case in the Jasper County Circuit Court was introduced by defendant. The petition in the ordinary form, for the recovery of city taxes for the years 1898 to 1902 inclusive, was filed September 15,1903. The answer pleads substantially the same facts with respect to the condition and situation of the *499land as in this case, and “that the pretended ordinance purporting to extend the corporate limits of the city so as to include the defendants, said land is unreasonable, unjust, and oppressive.” The only ordinance appearing in the transcript of the evidence introduced in that case is a general ordinance entitled, “An ordinance changing and diminishing the present corporate limits of Oarterville, Mo.” It provided that the corporate limits as they then existed, and described as containing more than four and a half sections of land, including the whole of the original town, with the land in controversy, be changed and diminished to metes and bounds containing less than half as much land, but still including all the old town. The process by which the city grew to its larger estate does not appear in the record of that case. The judgment was for the defendant. The court refused, in this case, to instruct, at the request of the plaintiff, that it was not an adjudication against the right of the city to tax the land in question, and did instruct at its request as follows:
“The court declares the law to be that if the evidence in the case of the State of Missouri ex rel. Al Pease, City Collector of the City of Carterville, v. Center Creek Mining Company shows that the question of the original incorporation of the city of Carterville was not submitted to the court in the determination of said cause, and that the question of whether said land was included in the original incorporation of the said city of Carterville was not one of the issues in said cause un-. der the pleadings and the evidence, but that the evidence in said cause shows that the question considered was the reasonableness of the corporate limits of the city of Carterville, as fixed by ordinance of the board of aldermen of said city as shown by ordinance No. 84. page 181 of the ordinance book of said city, then the judgment in the cause of State ex rel. Al Pease, City Collector of the City of Carterville, v. Center Creek Mining Company is not res judicata in the present *500cause.” It then gave judgment for defendant, which is now before us on this appeal.
Former Adjudication: Action by State for Taxes. I. The controlling question, and the one on which the decision of the trial court was placed, is whether or not the judgment in the Pease case es^°PS city from asserting that the land in question was subject to taxation for city purposes at the time these taxes were levied. There is much respectable authority to the effect that such an adjudication is only conclusive against the State as to the very taxes which were its subject, and does not extend to the incidental questions actually and necessarily decided in reaching the judicial result. This court has, however, adopted and followed the more just and reasonable doctrine that, in the absence of any constitutional or legislative declaration to the contrary, these rules, which it has established and which it enforces for the protection of the subject from vexatious and unnecessary litigation, should be and are binding upon the State itself. [Kansas City Exposition Driving Park v. Kansas City, 174 Mo. 425; New Orleans v. Bank, 167 U. S. 371; Nord St. Louis Turnverein v. Hagerman, 232 Mo. 693.] In the case last cited we said: “To our minds the matter was so exhaustively considered and so soundly reasoned in the Exposition Driving Park case, that no judicial excuse exists for a re-examination of its doctrine.” "We will assume, then, that the doctrine of res judicata and estoppel by judgment applies as well to cases of this character as to ordinary litigation between individuals, and consider its application from that standpoint. This was the view taken by the trial court in the instructions given and refused. Was it rightly applied ?
II. There is no question in this case as to the identity, of the parties with the parties in the Pease *501case, or of the capacity in which they sne. The plaintiff in each is the State, and the relator the collector of the city of Carterville, suing in that capacity, while the defendant is the same. But the thing sued for in the Pease ease was the amount of the city taxes for the years 1898 to 1902 inclusive, and the cause of action was its non-payment. The thing in issue and adjudicated was the liability of the land for those particular taxes, and when that was determined by the court and its determination had been embodied in its final judgment the very existence of the judicial branch of the government required that nothing should remain but to give effect-to the judgment by final process. “The very essence of judicial power is that when a matter is once ascertained and determined it is forever concluded when it arises again under the same circumstances between the parties or their privies.” [New Orleans v. Bank, supra.] The estoppel of the judgment embraces not only everything urged in support or interposed in defense of the cause of action in issue, but everything that might have been so urged or interposed; so that the judgment constitutes the ultimate measure of success on the one hand and of defeat on the other. While the defendant has the right to interpose as many consistent defences as he may think he has to the action against him, he has the equal right to plant his case upon the one he conceives to be the surest and .most available, and thus avoid the'trial of a swarm of possible issues which may involve him in almost endless expense and difficulty, and the courts charged with the hearing and determination of the case in much unnecessary labor. In doing this he only risks the subject-matter directly in issue in the particular suit, and does not run the risk of binding himself with respect to other matters by the fiction of an adjudication of things never tried or considered. Upon this point the Supreme Court of the United States in the New Orleans case, supra, quoting with approval from Cromwell v. *502Sac County, 91 U. S. 351-353, said: “Where the second action between the same parties is upon a different claim or demand, the judgment in the prior action operates as an estoppel only as to those matters in issue or points controverted upon the determination of which the finding or verdict was rendered. In all cases, therefore, where it is sought to apply the estoppel of a judgment rendered upon one cause of action to the matters arising in a suit upon a different cause of action, the inquiry must always be as to the point or question actually litigated and determined in the original action ; not what might have been thus litigated and determined. Only upon such matters is the judgment conclusive in another action.” This conclusion is supported in the case cited by an extensive collection of authorities from the same distinguished court which we have examined with much interest. In the light of the principles so stated we are to determine whether or not the questions involved in this case, a suit for city taxes for the years 1905 to 1909 inclusive, were “actually litigated and determined” in the Pease' suit for the city taxes on the same land for the years 1898 to 1902.
County Court Incorporating Town: Judicial Act. III. The plaintiff, for the purpose of making out its case in the first instance, introduced not only its certified tax bill, but also the original record of an order of the county court of JasPer county, made April 16, 1877, incorporating the town of Carterville, consisting of twelve forty-acre tracts in compact form, of which the tract involved in this suit is one. The regularity of this order is not questioned. It states all the facts necessary to give the county court jurisdiction under the act of February 8, 1871 (Laws 1871, p. 85), which was in force at the time it was made. That the authority given the county court by this act is judicial is not an open question.
*503order<ofUpon incorporation. *502[Kayser v. Trus*503tees, 16 Mo. 88; State ex inf. v. Fleming, 158 Mo. 558; Black v. Early, 208 Mo. 281, 303-4; State ex rel. v. Wilson, 216 Mo. 215, 277.] In the case last cited, in considering the action of the county court *n incorPorati°n of a drainage dis-trict, this court said .that “where such court, or a mere ministerial board for that matter, possesses under the law jurisdiction of a certain class of cases, and is required to find the existence of certain facts, the law will presume, in a collateral attack upon the judgment, that such facts did exist, and that such court or board passed upon them as required by statute.” In the Kayser case, which involved the incorporation of the town of Bremen under a law (Gleneral Statutes 1845, p. 1048) from which the Act of 1871 was copied, this court held that the county court having jurisdiction of the subject-matter and having- declared the town incorporated, the validity of its existence could only be questioned by a direct proceeding in quo warranto, and that in a collateral proceeding (which was, in that case, an application to enjoin the collection of town taxes) it could not be shown that the charter was obtained by fraud or had been forfeited by misuser or nonuser. This could only be done by process on behalf of the State.
Of the doctrine of that case, we said in Black v. Early, supra, “The Kayser case has been followed by a long line of cases from that day substantially to this, and if any cases be found in our reports that strike or seem to strike a discordant note they have in turn not been followed.”
*504Matters to be Pleaded. *503It is not necessary to consider whether or not quo warranto would lie to inquire into the propriety of the incorporation by the county court of this particular forty acres of land into the town of Carterville. While we hold that the validity of that action was not a proper subject of inquiry in the Pease case, we will assume that if the question was before the court in any form *504in that case, and was there litigated and decided, whether rightly or wrongly, the parties are estopped from questioning the force of that decision in this case. But the question of the validity of the judgment of the county court is not one that raises itself. This court has said that “to assail an order of the county court in the matter of incorporating a city or town, or to disturb the result of its judgment through the office of the writ of quo warranto, all the essential infirmities thereof, and iniquities therein resulting from the manner of its procurement, or the fraud of the court, must be alleged and proven with the same strictness that would be required in a bill in equity having for its object the amendment of the final judgment of any court of record brought about by fraud or collusion.” [State ex rel. v. Fleming, supra.]
Ordinance of Incorporation as City of Fourth Class Enlarging Boundaries. There was no attempt made in either the pleadings or the evidence in the Pease ease to attack or put in issue the validity or regularity of the judgment of incorporation. In short, the defendant seems to have assumed, as it now argues in its brief, that the ordinance of 1897 “changing and di- .... ... mimshmg the present corporation limits the city,” ignored all previous existence of the corporation, and was equivalent, for all purposes, to the establishment of a new corporation, by ordinance instead of by judgment of the county court as then provided 'by law. [R. S. 1899, sec. 5257.] A complete answer to this is that the city had no such power. When the original town became a city of the fourth class, its jurisdiction was not affected, but its limits and boundaries remained the same after such organization as before. (Id., sec. 5895.) The city had no power to interfere with these boundaries except to extend them over adjacent lands, or to diminish them by excluding territory therefrom. [Ibid.] The power to annex territory is sui generis *505in the sense that it creates one of the interested parties to an adversary transaction the legislative agent of the other with power to hind its antagonist, who has neither voice in the creation of the officers who inaugurate the action, nor vote in the election by which it is confirmed. It is this reason upon which the doctrine that the reasonableness of such an ordinance is a subject of judicial inquiry in suits to enforce rights claimed thereunder is founded, and we have justly said that the doctrine runs like a thread of gold through our case law, and is too firmly buttressed on reason and authority to be now mined by hostile criticism. [State ex rel. v. Birch, 186 Mo. 219, and cases cited.] In pursuance of this doctrine the defendant pleaded in the. Pease case, and introduced evidence for the purpose of proving, that the ordinance of 1897 was, so far as it might apply to this land by including it in the city limits, unreasonable and void. Neither by pleading nor evidence was the validity of the judgment of incorporation now before us questioned nor is there anything in that record suggesting that it was considered. We therefore hold that the trial court erred in its ruling that the propriety of the inclusion of this land in the original incorporation of the town of Carterville was a thing adjudicated in the Pease case, so that' the plaintiff is estopped from claiming in this case that it is taxable for city purposes.
Assessment of Taxes: City of Fourth Class: Valuation not to Exceed that for County Purposes. IV. The question remains whether the assessment for city taxes of 1906 and 1907 is invalid because it does not “conform” to the assessment for State and county taxes for the same years. The certification of this assessment by the county clerk, who is made by the statute the secretary of the county board of equalization and therefore its certifying officer, is undoubtedly the certification of the board, and a sufficient authentica*506tion; but the corrected land list of the county assessor is the original record of the equalized assessment, and the city assessment must yield to this best evidence. [R. S. 1909, secs. 11372, 11397,] With this in mind and the Constitution and statute before us, we have no difficulty in the solution of this question.
The statute under which the city assessment was made (R. S. 1909, sec. 9347) was intended to conform to that provision of section 11 of article 10 of the Constitution which requires that the valuation of property for taxation for town, city or school purposes shall not exceed the valuation of the same property for State and county purposes. It provides that “in cities of the fourth class, the city assessor shall jointly, with the county assessor, assess all property in such cities, and such assessment, as made by the city assessor and county assessor jointly and after the same has been passed upon by the board of equalization, shall be taken as a basis from which the board of aldermen shall make the levy for city purposes. ’ ’ It also provides that ‘ ‘ the assessment of the city property, as made by the city and county assessor, shall conform to each other, and after such board of equalization has passed upon such assessment and equalized the same, the city assessor’s books shall be corrected in red ink in accordance with the changes made . . . and so certified by said board, and then returned to the board of aldermen.” In this case no attempt was made to conform to the method so prescribed, either in form or substance. The city assessor valued the land, independently of the county assessor for each of the years in question at $80,000', while the county assessor valued it for each of those years respectively at $2000 and $12000, which was raised by the county board of equalization to $6000 and $15,000' respectively. The record of this action, both of the county assessor and board of equalization, was ignored by the county clerk in the list certified by him to the board of aldermen. We are not called upon *507to speculate as to the reasons of these officers for their disregard of the plain requirement of the Constitution and laws made to give effect to its provisions, nor can we make an assessment for them. We can only say that this record shows a total lack, both in form and substance, of a legal assessment of this land for the city taxes of 1906 and 1907 and there can be no recovery for them in this suit.
The judgment of the trial court is reversed, and the cause remanded for disposition in conformity with this opinion.
