An act of the legislature, approved February 21, 1899, is involved in this appeal (Acts 1899, p. 73, §5903 Bums 1908). The act in question is entitled: “An act concerning the construction of court-houses in counties having a popnlation of more than 25,000 as shown by the last preceding United States census, and declaring an emergency.” Section one, omitting the enacting clause, is as follows: ‘ ‘ That it shall be unlawful for the board of county commissioners of any county having a population of more than 25,000, as shown by the last preceding United States census, to order or contract for the construction of any courthouse in such county unless a petition therefor be filed by at least 500 reputable resident freeholders of said eomfi^. Any order or contract made in violation of the provisions of this act, shall be null and void: Provided, that the provisions of this act shall not apply to the relocation and erection of court-houses pursuant to the provisions of an act passed *411over the Governor’s veto March 9, 1895. Acts 1895, p. 217.” Section two declares an emergency.
On August 9, 1905, a petition praying for the construction of a court-house on the public square in the city of Peru, the county-seat of Miami county, was presented to the board of commissioners of said county. This petition upon its face purported to be signed by 573 reputable resident freeholders of said county. The following are some of the reasons assigned therein to show the necessity for building a courthouse: “(1) The present court-house is fast falling into a condition of decay, and is now almost untenantable. There is a constant danger of some part of it giving away, and its condition constitutes a menace to the safety of all who are required to occupy it or resort to it for the transaction of business. To repair it would'cost a large sum of money, and it would still be an old court-house, antiquated in design, incommodious in its arrangement, and utterly insufficient in size for present needs. (2) The present court-house has not room to accommodate with offices more than one-half the county officers who are required to keep an office. The county sheriff, county assessor, county surveyor, county superintendent and county coroner are all without offices in the court-house. Nor is there any room for the county commissioners, for library, for witnesses, for consultation nor rooms for the judge in connection with the court room, and the only jury rooms are the mansard roof, from which a jury could not hope to escape in case of fire below. No alterations or remodeling of the present structure could remedy these defects or provide the additional rooms necessary for the proper transaction of the county business. ’ ’
After this petition had been considered by the board of commissioners, the board entered of record its finding as follows: “Having duly considered said petition, do find that there is in said Miami county a population of more than 25,000, as shown by the last preceding United States census of 1900; that said petition is duly signed by more than 500 *412reputable resident freeholders of said county, and that on account of the inadequate condition of the present structure to meet the wants of the public, and the decaying conditions of the present court-house in said county, a public necessity exists for the construction of a new, modern building and court-house. ’ ’ Upon this finding the board of commissioners ordered that a new court-house be constructed on the site of the old one, and that estimates therefor be submitted to the county council of said county at its next regular session in September, 1905, stating the amount required for the construction of said new court-house. On December 18, 1905, after ordering the construction of the court-house, the board of commissioners appears to have entered into a contract with appellees, as architects, to prepare plans and specifications for the construction of the new court-house, and to superintend and direct the building thereof. At its February session, 1906, the board of commissioners of said county ordered that the claim of $2,550, presented by appellee for services in preparing preliminary plans and drawings under the contract hereinbefore mentioned, be allowed. Appellant, Milton Kraus, a resident taxpayer and citizen of the county, upon making the required affidavit, appealed to the Miami Circuit Court from the order of the board allowing appellees ’ claim. After the case on appeal had reached the latter court, the cause was venued to the Cass Circuit Court, wherein appellant filed an answer to appellees’ claim. This answer, among other things, alleged that Miami county has been and is a county within the State of Indiana, having a population of more than 25,000; that on August 10, 1905, a petition was filed by 400 resident freeholders of said county, and no more, praying that the necessary steps be taken for the erection of a modem court-house in Peru, Indiana. It is further averred “that said board of commissioners, on said day, having considered said petition, made and entered of record a false, erroneous and void entry and order to the effect that such petition was signed by more than 500 reputa*413ble resident freeholders of said county, and ordered that a new court-house be constructed on the site of the old one.” It was further alleged in the answer “that the total number of names signed to said petition was 573; that of this number 175 were not at the time of the presentation of said petition resident freeholders of said Miami county, and were not, therefore, lawful petitioners; that of this number twenty-seven had each affixed their names twice to said petition, and had been counted twice in making up said 573 names. Eighty names signed were the names of nonresidents of Miami county. Eight were the names of persons who were dead at the time of the presentation of said petition, and 131 were names of signers who were not resident freeholders of Miami county, Indiana, at said time, leaving but 398 qualified signers to said petition.”
Appellees successfully demurred to this answer, and appellant refused to plead further, but elected to abide by his answer. Thereupon judgment was rendered against him on the demurrer.
From this judgment he prosecutes this appeal, and assigns as error the ruling of the Cass Circuit Court in sustaining the demurrer to his answer.
The theory of appellant, as advanced by his counsel, is that inasmuch as it appears that Miami county has a population of over 25,000, as shown by the census of 1900, the act of 1899, supra, is applicable thereto; that, in the absence of the petition required by said act, the order made by the board of commissioners of said county for the construction of the court-house in question is absolutely void; that the board had no authority to enter upon the construction of a court-house or make any contracts in respect thereto; that, therefore, the contract made between the board and appellees is void and no claim for services thereunder is valid or enforceable against the county. Counsel assert that because appellant alleged in his answer that no such petition as the one required by the act in question was presented to the *414board, of commissioners, signed by tbe number of freeholders as prescribed by the statute, the board therefore was, under the law, deprived of all power to order the construction of the court-house in question, and hence “the fact, that the board entered of record a false finding, to the effect that the petition so filed was signed by more than the requisite number of reputable freeholders,, cannot operate to confer on it the power denied by the statute.” Counsel further say that “while such a finding might operate to save the board’s decision from being held absolutely void as against a collateral attack, if it is to be considered as exercising judicial functions in said matter, still in a case where its acts and decisions are directly attacked by an appeal, as in this case, the false finding which the board has entered of record cannot avail to confer on it an authority denied to it by the statute.”.
1. •By reason of the view which we entertain in respect to the validity of the statute involved, it is not essential that we take up the consideration of appellant’s right to assail, as he does under his answer, the order of the board of commissioners for the construction of the court-house in question. It may be said that the record in this case presents the question in regard to the constitutionality of this statute, although its validity has not been controverted in the briefs or 'arguments of counsel for appellees. Nevertheless appellant, under his assignment of errors, alleges that there is manifest error disclosed by the record in the ruling of the trial court in sustaining the demurrer to his answer, and he therefore demands a reversal of the judgment. Appellees allege that there is no error, consequently the burden is cast upon appellant to establish by the record the error which he has assigned. Appellees are entitled to a decision by this court on every point or proposition which will prevent a reversal of the judgment- below upon the errors assigned, although not pointed out in their brief or ar*415gument. Their mere silence upon the point presented by the record herein, going to sustain the judgment of the lower court, will not be regarded as a waiver by them of such point. While we do not search the record in a case for errors not pointed out by the appellant in his brief or argument, nevertheless we may, and generally do, search the record in order to discover points or propositions thereby presented which will operate to affirm the judgment of the lower court. Or, in other words, we are not to ignore that which the record discloses, if it will prevent a reversal of the judgment. This rule is well settled by decisions of this court. Martin v. Martin (1881), 74 Ind. 207, 209, 210; Travelers Ins. Co. v. Prairie School Tp. (1898), 151 Ind. 36; Wilson v. State (1901), 156 Ind. 631.
2. As we view the statute, it is clearly antagonistic to §22, article 4, of the state Constitution. Consequently we cannot ignore its constitutional infirmity merely because appellees have not assailed it in their briefs. We are not unmindful of the well-affirmed rule that all reasonable presumptions must be indulged in favor of the validity of an act of the legislature, and it is only when its invalidity appears so clearly and palpably as to leave no room for a reasonable doubt that it violates some provision of the Constitution that a court will refuse to affirm or sustain its validity. For the reasons hereinafter given we are free to affirm that we entertain no reasonable doubt as to the invhlidity of this act. It is declared by §22, supra, that “the General Assembly shall not pass local or special laws in any of the following enumerated cases, that is to say: * * * Regulating county and township business.” Article 4, §23, emphasizes what the provisions of §22, supra, were intended to bring about in respect to laws enacted by the legislature upon cases or subjects therein enumerated, for said §23 declares that “in all the cases enumerated in the preceding section, and in all other cases where a general law *416can be made applicable, all laws shall be general, and of uniform operation throughout the State.” (Our italics.)
3. That the constructing of a court-house by a county for county purposes is county business within the meaning of the phrase “regulating county and township business, ’ ’ as contained in §22, supra, is sustained and settled by the decision of this court in Board, etc., v. State, ex rel. (1904), 161 Ind. 616. That the act of 1899, supra, in undertaking to restrict the building of court-houses in counties having the prescribed population, is a regulation of county business, is settled by the decision of Board, etc., v. State, ex rel., supra. This court, in that case, in considering what constitutes the regulation of county business, as contemplated by §22, supra, said: “To regulate is to direct by rule or restriction.” Citing authority.
4. Section 5989 Burns 1908, §5748 R. S. 1881, makes it the duty of the board of commissioners of every county in this State to cause a court-house, jail and other public offices for the county to be erected and furnished, where such duty has not already been performed, and such board is also required under this section to keep the public buildings of the county in repair. In Kitchel v. Board, etc. (1890), 123 Ind. 540, in considering this statutory provision, the court said: “It was necessary that the power to determine when the public interests demanded that the courthouse in any county should be repaired or rebuilt, or whether it should be superseded by a new one, should be lodged somewhere. The legislature has seen fit to entrust that power to the board of county commissioners, and while the board acts within the discretion committed to it, there is no place for judicial interference, until it is clearly shown that the commissioners are acting fraudulently or corruptly, and in violation of their duty as public officers.” See, also, Robling v. Board, etc. (1895), 141 Ind. 522.
*4172. *416At and prior to the passage of the act of 1899 the right or power to determine whether a court-house should be con*417strueted, or whether an old court-house should be replaced by a new one, was, under the law, lodged in the sound discretion of the board of commissioners of such county. By the act here involved the board of commissioners, in each county of this State having a population of more than 25,000, as shown by the last preceding census, is absolutely restricted from ordering the construction of a court-house and from entering into any contract for its construction, unless, as a condition precedent to such order or contract, a petition therefor is presented to the board, signed by at least 500 reputable freeholders of such county, and “any order or contract made in violation of the provisions of the act” is declared to be null and void. This certainly may be said to be a drastic regulation by the legislature in respect to the board’s taking the initial step in the matter of the construction of a county court-house. In all other counties of the State not having the prescribed population, the board is left unrestricted and unregulated under the provisions of this statute in the exercise of its discretionary power in regard to the construction of a court-house.
*4185. *417The legislature, in enacting the statute in question, may be said, in theory or effect at least, to have divided the ninety-two counties of the State into two classes — the first to be composed of all counties having a population of over 25,000, as shown by the last preceding United States census. All other counties which were not shown to have the population required are to constitute the second class. We judicially know that by the United States census of 1890, which was the last census preceding the passage of the act, there were only twenty-eight counties which had a population of over 25,000. The remaining sixty-four counties did not have the required population. By the United States census of 1900 there were thirty-nine counties which had a population necessary to bring them into the first class. Each of the remaining fifty-three came within the second class. As shown by *418the census of 1890, Shelby county had a population of 25,454, while Jefferson county, the next highest to Shelby, had a population of 24,507; there being a difference of 947 between these two counties. It is evident, therefore, that at the time the statute in question took effect on February 21, 1899, it applied to and regulated the action of the board of commissioners of Shelby coiyity in the construction of a court-house, in the event the erection of one was necessary. But it had no application whatever to Jefferson county, although there was a difference of only 947 in the population of the two counties. If, during the year of 1899, after the taking effect of this act, the court-houses of Shelby and Jefferson counties had each been destroyed by fire, the commissioners of the former county could not have caused another court-house to be erected unless petitioned therefor by 500 freeholders of that county; while, on the other hand, the board of Jefferson county could have proceeded, unrestricted and unregulated by this statute, to replace the court-house so destroyed. As shown by the census of 1900, Ilenry county had a population of 25,088, while the population of Bartholomew county was 24,594, a difference of only 494. Nevertheless the act has no application whatever to Bartholomew county, but operates to restrict and regulate the board of commissioners of Ilenry county in the matter of the construction of a court-house. Certainly, in the need for a court-house, there can be no real difference between a county having a population of 24,000 and one having 26,000. Of course if the legislature were dealing with a classification under §23, supra, then it might be said that the line must be drawn somewhere, and that the question where it should be drawn was one for the determination of' the legislature. Conceding for the sake of argument that in enacting a law upon any subject enumerated in §22, supra, the legislature may resort to a classification, and thereby make a general law within the meaning or contemplation of that section, nevertheless, under such circumstances, there *419must be a real reason or necessity for the classification, and the necessity or reason “must inhere in the subject-matter and must be natural and not artificial, ’ ’ and the question as to whether the classification comes within the rule herein asserted would be one reviewable by the courts. Town of Longview v. City of Crawfordsville (1905), 164 Ind. 117, 68 L. R. A. 622; Edmonds v. Herbrandson (1892), 2 N. Dak. 270, 50 N. W. 970, 14 L. R. A. 725.
2. We may with propriety inquire what reason or necessity exists in respect to the matter of the construction of a courthouse that the act should be made applicable to some of the counties and not to others. Why the distinction ? Can the classification of the counties by population under this statute be said to be one based upon some real and reasonable ground inherent in-the subject-matter, one which bears a just and proper relation to the classification as made, or is the classification in question purely arbitrary? That it is merely arbitrary is, in our opinion, beyond controversy. In fact no reason other than the mere artibrary will of the legislature can be suggested for the classification in question. The act is not so framed as to be general or of uniform operation in all of the counties of the State, and its provisions clearly disclose that this was not the legislative purpose in its enactment. It is as effectually local in its character and nature as though at the time of its passage it applied only to one of the ninety-two counties instead of to twenty-eight. It has been repeatedly held by this court, since Gentile v. State (1868), 29 Ind. 409, that in cases or subjects not enumerated in §22, article 4, of the Constitution, then under that part of §23, article 4, thereof, which we have italicized, it is the exclusive province of the legislature to determine whether a general law can or cannot be made applicable to all parts or localities of the State, and the determination of that question by the legislature is not reviewable by the courts.
In Town of Longview v. City of Crawfordsville, supra; *420in considering the question as to whether an act of the legislature which provided for the extension of corporation boundaries of cities having a 'population, according to the last preceding United States census, of between 6,000 and 7,000, was special legislation, and therefore violated §13, article 11, of our Constitution, which provides that “corporations, other than banking, shall not be created by special act, but may be formed under general laws,” this court said: “It is contended that, as said act applies to all cities having between 6,000 and 7,000 population according to the last preceding census, such classification takes it out of the category of special legislation and makes it a general law. In jurisdictions where classification is permitted by the organic law, it is settled that the same, in order to furnish a basis for legislation that will exempt it from the charge of being special, must be classification which, in the nature of things, suggest^ and furnishes a reason for and justifies the making of the class. The reason for the classification must inhere in the subject-matter, and the same must be natural, not artificial. Under this rule, neither mere isolation nor arbitrary selection is proper classification. ’ ’ Citing numerous authorities.
In Lodi Tp. v. State (1889), 51 N. J. L. 402, 18 Atl. 749, 6 L. R. A. 56, the court said: “The rule is, that in any classification for the purpose of a general law, all must be included and made subject to it and none omitted that stands upon the same footing regarding the subject of legislation. To omit one so circumstanced is as fatal a defect as to include but one of a number.”
In State, ex rel., v. Parsons (1878), 40 N. J. L. 1, in considering special lawSj the court said: ‘ ‘ Interdicted local and special laws are all those that rest on a false or deficient classification; their vice is that they do not embrace all the class to which they are naturally related; they create preferences and establish inequalities; they apply to persons, things or places possessed of certain qualities or situations, and exclude from their effect other persons, things or places *421which, are not dissimilar in these respects.” See, also, Bedford Quarries Co. v. Bough (1907), 168 Ind. 671.
6. The act of 1899, supra, for the reasons herein given, is so clearly a special or local law to regulate county' business within the interdiction of §22, supra, that further comments and citation of authorities are unnecessary. Certainly the legislature cannot under this section of our fundamental law be permitted to accomplish indirectly that which it cannot do directly. The statute being invalid, upon no view of the case can it afford appellant a basis upon which to predicate his cause of defense to appellees’ claim. Therefore, the demurrer to his answer was properly sustained.
Judgment affirmed.
