delivered the opinion of the court:
Plaintiff in error filed its bill in the superior court of Cook county against defendants in error, as county treasurer and county clerk of Cook county and town collector of the town of South Chicago, in that county, praying for an injunction restraining the collection of the excess of taxes extended against it above the sum of $22.13, which would be the amount of its taxes on an assessment of $200. Demurrers to the original bill were sustained. The bill was amended and demurrers to the amended bill were overruled, and the defendants were ruled to plead or answer. Thereupon the defendant the collector of the tow'll of South Chicago filed his plea that there was no money due from complainant for taxes, and that he had not in his hands any warrant for the collection of a tax from it. The defendants the county clerk and county collector filed similar pleas. The abstract does not show any action on these pleas, but complainant, by leave of court, filed a supplemental bill reciting the previous proceedings, and alleging that afterwards, while the case was pending in court, the town collector, armed with his warrant, by means of threats to levy on and take possession of complainant’s property, which he was about to execute, made a compulsory collection of the entire tax, $553.20, which complainant paid under protest, and that this compulsory payment was the sole defense alleged by the pleas. The demurrers previously filed were ordered to stand to this supplemental bill, and the court sustained them. Complainant elected to stand by its bills, and the amended and supplemental bills were dismissed for want of equity.
The facts appearing by the amended and supplemental bills, to which the demurrers were sustained and which were thereby admitted, were in substance as follows: The entire personal credits and effects, including cash on hand *388or money in bank, owned by complainant on May 1,1897, were of the fair cash value of $2000. After the fourth Monday of June, and during the month of July of that year, complainant received a notice from Richard C. Gunning, the asséssor of the town of South Chicago, that its property had been assessed at $20,000, whereupon it made and filed with the assessor a schedule of its taxable property and assets in the town. The schedule showed a total value of $2000, and was received and accepted by the assessor. Other personal property in the town was assessed at not to exceed ten per cent of its fair cash value, and at the rate at which such other property was assessed complainant’s assessment would have been $200. Upon receipt of the schedule the assessor promised to assess the property at ten per cent of the fair cash value therein stated, but without notice to the complainant and disregarding his agreement he-asspssed the property at $5000. This assessment was willfully made, as a part of a general plan to assess complainant and other selected persons, firms and corporations at a disproportionate and excessive rate, to extort money as a bribe for a reduction to the uniform rate applied to property in general, and persons who represented themselves to be emissaries of the assessor, and were charged to have been his representatives, offered to reduce the assessment to a satisfactory amount upon payment of money therefor. On July 12, 1897, complainant filed with the county board an application for the revision of the assessment, and after-wards filed an amended application, and appeared before the board and introduced evidence in its support, which was heard by the county board and the application taken under advisement. The county board neither granted nor denied the application. It was referred to the finance committee, and that committee reported, as to this and other applications, that they had decided to make no recommendation except that the complaints be placed on file without prejudice to complainants’ appeal' to the *389courts. This report was adopted by the board. Again, on September 27, 1897, the finance committee made another report to the board on the subject of equalizing valuations between the towns of Cook county, reciting, among other things, the existence of unfair assessments and inequality and injustice between individuals which it was impossible for the board to go into further than had been done, and containing a resolution that the assessments as returned by the assessor, with certain reductions made by the county board, should be declared to be the assessments for the year 1897. This report was also adopted by the board, and by this action the county board refused to act upon the application of complainant and to decide the question of complainant’s grievance submitted to it under the statute. Complainant’s application was then placed on file under this order that it should be without prejudice to its appeal to the courts. Taxes were assessed upon this fraudulent assessment to the amount of $553.20.
This case has been argued with five others, and counsel say that the six cases present substantially the same questions. We find, however, that there is an important difference between this case and the others, which renders a .considerable part of the argument entirely inapplicable. This difference is, that in the other cases the property was assessed at less than its fair cash value, and as to them it is urged that the only real complaint is. that the complainants therein were assessed at a higher rate than others. The argument that there is no just cause of complaint where the assessment does not exceed the fair cash value, although others are assessed at a less rate, cannot be applied to this case, since the fair cash value is $2000 and the assessment $5000. The question in this case is, whether complainant could have relief against an excessive assessment which was made .with full knowledge of the facts and from a wrongful and fraudulent motive..
*390The law provides for a valuation of property by the assessor. The statute has also provided a board of review, and a further revision by the county board, for the protection of a tax-payer who may consider himself aggrieved by the opinion or judgment of the assessor. Value is largely a matter of opinion, and the opinions of these officers, when honestly exercised and applied upon a basis authorized by the law, cannot be reviewed or revised by the courts. The provisions of the statute are intended to be sufficient to reach the ends of justice between the tax-payers, and there is no appeal to the courts in mere matters of judgment. The assessor and boards for review are invested with the only power to fix valuations, and their decisions can only be questioned for fraud or want of jurisdiction. (Chicago, Burlington and Quincy Railroad Co. v. Frary, 22 Ill. 34; Spencer & Gardner v. People, 68 id. 510; Republic Life Ins. Co. v. Pollak, 75 id. 292; Illinois Central Railroad Co. v. Hodges, 113 id. 323; St. Louis Connecting Railroad Co. v. People, 119 id. 182; Illinois and St. Louis Railroad and Coal Co. v. Stookey, 122 id. 358; Spring Valley Coal Co. v. People, 157 id. 543; Keokuk Bridge Co. v. People, 161 id. 514.) But while it is not the duty of courts nor within the power of equity to supervise the honest judgments of statutory officers as to valuations, equity will interfere if the valuations are fixed from improper motives and in disregard of duty. The law authorized the assessor to exercise his judgment as to the value of property, but not to enter upon a system of pillage and plunder and to make use of his office to carry it out. Courts of equity have always relieved against fraud, and even the most solemn judgments are vitiated by it. If an assessor, under cover of his office, with intent to defeat the justice and uniformity required by the'law or for the corrupt motive of obtaining a bribe, steps aside from his duty'to accomplish such a purpose, the wrong inflicted may be redressed in equity and the assessment will be vitiated by the fraud. (Cooley on Taxation, 157, *391526, 547; Porter v. Rockford, Rock Island and St. Louis Railroad Co. 76 Ill. 561; Pacific Hotel Co. v. Lieb, 83 id. 602; Chicago, Burlington and Quincy Railroad Co. v. Cole, 75 id. 591; Illinois Central Railroad Co. v. Hodges, supra; Spring Valley Coal Co. v. People, supra.) It is the'rule that au excessive valuation, merely, does not establish fraud, but the attending circumstances may be such as to lead to the conclusion that it was fraudulently and dishonestly made. (Pacific Hotel Co. v. Lieb, supra; Spring Valley Coal Co. v. People, supra.) The facts alleged in this case, which we must assume to be true, are, that the property of complainant was assessed at two and a half times its cash value as part of a general plan of dishonest spoliation, by which complainant and others were selected as victims from whom bribes might be obtained, and these bribes were solicited by representatives and emissaries of the assessor. The result of this scheme was a corrupt, fraudulent and excessive assessment of complainant’s property, and it should be set aside, unless complainant is barred from relief in a court of equity by submitting to be sent away from the statutory board without a hearing and decision.
Complainant presented its grievance to the county board, and that board undertook to divest itself of the duty imposed upon it by law by resolving that it was impossible to go into inequalities and injustice against individuals and to hear and decide the case as required by law. Its committee made no recommendation except that the complaint be placed on file without prejudice to complainant’s appeal to the courts. This report was adopted by the board and complainant was" ordered to take its departure from that forum without a decision. This was no more or less than a refusal of the board to do its duty, and the law would have compelled its performance on the application of complainant. It is said by Judge Cooley of the writ of mandamus: “A suitable case for the employment of the writ is where it is found necessary to *392compel county commissioners to proceed to the hearing of an appeal from an assessment, where the hearing is of right under the statute.” (Cooley on Taxation, 521.) Following this rule, in the recent cases of Beidler v. Kochersperger, 171 Ill. 563, and Kochersperger v. Larned, 172 id. 86; where there was similar conduct on the part of the county board of Cook county, it was held that mandamus would lie to compel a consideration of the complaint. Upon being sent away from the county board complainant did not pursue a remedy which the law affords and which is intended to be adequate for the relief of the tax-payer;
It has always been held that equity would enjoin the collection of a tax upon property exempt from taxation, and the question as to what effect the failure to follow the statutory remedy will have as to such a tax has been before the court several times. Section 97 of the Revenue act provides for a hearing and determination by the county board of the question whether property is exempt from taxation, and for an appeal from such decision, when, the Auditor shall present the case to this court for fiual decision. In Preston v. Johnson, 104 Ill. 625, it was charged in a bill in equity that a tax was illegally levied upon property not subject to taxation. There had been an application to the county board, where it was claimed that complainants were denied a hearing, but it was held that there was an adequate remedy at law, and tha,t if complainants were aggrieved by any action whatever of the board, their plain remedy was by an appeal. It was there said that the remedy through the county board of review and by appeal is adequate and exclusive. In Peoria Fair Ass. v. People, 111 Ill. 559, the association petitioned the county board to strike its lands from the assessment roll, but the board refused the petition and no appeal was taken. It was held that on application for judgment the defense could be made, and that it was only in case the question had been brought before this court and this court had passed- upon it that-the party *393would be concluded, when the question would be res judicata. The decision in Preston v. Johnson was afterward explained in Illinois Central Railroad Co. v. Hodges, supra, and it was said that if a party selects the remedy provided by the statute he will not be allowed to abandon it and then g'o into equity, but he may go into equity in the first instance and have relief. It was held that the remedy afforded by the statute is adequate and when selected is exclusive, but before-the selection of a tribunal it must be regarded as only affording a cumulative remedy. In those cases, however, the statute then under consideration gave a direct means of obtaining the judgment of this court upon the question involved while there is no appeal to a court on a question of over-valuation, and the further material distinction was pointed out in the latter case that an assessment of exempt property is an act without jurisdiction.
Where property is exempt from taxation the owner has a right -to assume that the law will be observed, and he is not required to take notice of its illegal assessment nor to appear before the local tribunal, but'is protected by the law and may resort to a court of equity for an injunction. When complaint is made that the assessor has over-valued the property, whether as a mistake of judgment or from whatever motive, the situation is different. The property is subject to assessment, and it is the duty of the owner to take notice of the assessment. The valuation is not an act without jurisdiction or authority, and if it is excessive the law intends that application shall be made to the board. The statute embraces every kind of grievance in the assessment, and whatever its nature may be, the tax-payer may make his complaint known and have a hearing. (Felsenthal v. Johnson, 104 Ill. 21.) It was proper for complainant to appeal to the county board directly, as the assessment was made after the fourth Monday of June. This remedy afforded by the statute is intended to be sufficient for the relief of the *394tax-payer. The statute permits a grievance of the kind complained of here to be heard, and presumably that remedy «will be adequate.
In Spring Valley Coal Co. v. People, supra, where fraud was charged, the coal company applied to the town board of review and secured reductions in some of the values, and on appeal to the county board there was a hearing, where it obtained still further reductions in value. It was there said that, assuming the assessment to be fraudulent, the coal company availed itself of the remedy given by the statute and the decision made by the board of supervisors was final and conclusive, and it must be regarded that the fraud, if any, that there was in the original assessment was purged out of it. In that case the presumption that the owner had obtained full relief was indulged; but if he does not obtain relief as against a fraudulent assessment we do not think that the statute is the sole remedy. Fraud is a familiar ground of equity jurisdiction, and if an assessment is fraudulent, equity should relieve against it where the tax-payer has been diligent in seeking the remedy which the statute affords. In matters of revenue it is important that all questions should be speedily settled, and the tax-payer should first seek the remedy given by the statute, which it is presumed will be sufficient. If he fails to do so it is his own neglect or folly. The remedy against fraud is of an equitable nature, and should be applied where the injured party has been diligent for his own protection, but we think it should be withheld in a case of this kind, where the party has failed to insist upon a legal right which probably would have given full relief. The reports of the committee to the board plainly show that in its judgment assessments returned by some of the assessors, and complained of, were unequal and unjust. The board merely refused to do its duty and decide the cases. Although complainant was denied a hearing before the county board it had an adequate remedy to compel its perform*395anee. It is said that this remedy was insufficient, because it would not stay a collection of the tax while the proceeding was pending. If complainant was pursuing its legal remedy, and had not obtained it when a collection of the tax was attempted, an entirely different question would be presented. The mere fact that it might not get a hearing before an attempted collection of the tax would not justify an abandonment of its legal remedy and the resort to a court of equity.
The fact that the abstract does not show what-was done with the pleas of defendants is immaterial, in the view taken of the case. The bill was filed and the court had acquired jurisdiction of the subject matter and the parties. Complainant had prayed for an injunction, which had not been secured, but after the court had acquired jurisdiction, if the collector enforced payment of the tax that fact would not constitute any defense to the bill, but the money was collected subject to the power of the court to compel the collector to refund it or submit to such other decree concerning it as might be equitable. A party filing a bill for an injunction may fail to procure a preliminary injunction, but any act after the court has acquired jurisdiction will be subject to the power of the court to compel a restoration of the status or to enforce such other relief as may be proper. Pleas making such a defense would be insufficient as answers to the amended bill,, but the final decree of the court dismissing the amended and supplemental bills was correct, as we think, for the reason given, that complainant had not availed itself of the remedy secured to it by the statute to be relieved from the wrong complained of in the bill before seeking such relief in a court of equity.
The decree of the superior court will therefore be affirmed.
Decree affirmed.
