delivered the opinion of the Court:
Various exceptions were taken to the answers in this case, for immateriality, irrelevancy, and on account of scandalous matter contained in them; but the exceptions do not, as they should do, set forth the parts of the answers excepted to. It is referred to only as set forth on certain specified pages and lines of the answers, and as their paging has not been, by the circuit clerk, preserved in the record, we are unable to say, therefore, whether the exceptions were properly sustained or not.
The plaintiffs in error sought, first by demurrer, and after-wards by their answers, to question the authority of complainants’ counsel to bring this suit. Failing to accomplish their purpose, and after the suit had been pending for nearly two years, they then make their motion to dismiss for the want of such authority. The court very properly overruled this motion. It was of a dilatory character, and should have been made at the first opportunity, and it could not be properly raised by demurrer or answer. Counsel for plaintiffs in error have presented no authorities upon the subject, or. referred us to any statute bearing upon it, and we know of > none, except that by part second of section 5, chapter 14, of the Eevised Statutes, it is made the duty of the State’s attorney to prosecute “all forfeited bonds and recognizances, and all actions and proceedings for the recovery of debts, revenues, moneys, fines, penalties and forfeitures accruing to the State, or his county, or to any school or road district in his county; ” and by section 5 it is made the duty of the court, whenever he is absent or unable to attend, or is interested in any cause or proceeding, civil or criminal, to appoint some competent attorney to prosecute or defend such cause or proceeding. It is said, and so appears from the record, that the State’s attorney had been employed by some of the parties interested, before this litigation arose, regarding one of *273the questions involved in this case, and had this motion been made in apt time, the court would have doubtless appointed complainants’ solicitor, or some other competent attorney, to prosecute this suit. The collection of the public revenues is of the utmost importance, and no court should allow a suit of this character to be dismissed because the solicitor who brings it may not happen to be the State’s attorney or the Attorney General, without good cause shown therefor. There is no statute requiring a bill of this kind to be signed in the official character of either of those officers, as there is with reference to an indictment.
Complaint is made that these lands and lots were fraudulently assessed at a far greater value in proportion than other lands and lots in the same assessment district. Even if this is so, this objection can not be raised in this proceeding. The law has designated a certain person to assess and fix a value upon property for purposes of taxation, and given a remedy to parties aggrieved by his action, to have the same reviewed. If parties neglect this opportunity, they at least can not contest the matter in a suit like this, brought to enforce the lien given- by the statute against the lands for the non-payment of the taxes. The action of the board of supervisors in appointing a committee to re-assess these lands for the purposes of taxation, and their compromise with plaintiffs in error regarding the State and county taxes, was clearly unauthorized; but whether so or not, their proceeding in regard thereto has been reversed and set aside by a court of competent jurisdiction on writ of certiorari, which is binding upon every one so long as it remains in full force, and plaintiffs in error can not therefore invoke the action of the supervisors as a defence here; but so far as they have paid to the proper collecting officers any taxes, penalties or costs, under said arrangement with the supervisors, they are entitled to a credit therefor in this proceeding.
*274Counsel for plaintiffs in error are wrong in supposing that when exceptions to an answer are sustained, therefore the answer is taken as true. The case of Prettyman v. Barnard, 37 Ill. 105, does not announce such a rule, but holds only that-where the exceptions are disallowed, and counsel elects to abide by them, and files no replication, then the answer will be taken as true. In this case an answer under oath was waived, and exceptions could therefore be taken only to such matters therein as should be regarded as irrelevant, impertinent or scandalous, and it would be a very strange doctrine to hold that because, exceptions were taken and sustained to such matter, therefore the rest of the answer must be taken as true, even though, as ivas done in this case, a replication was filed.
Nor was there any error in the court refusing, as is claimed, to pass upon the competency of evidence, as it was offered for its consideration. The court stated, at the time of the offer, that it would be admitted subject to the objection, and such weight given to it as the court might think it was entitled to. It is familiar law, in chancery practice, that the admission of incompetent evidence on the hearing is not cause for reversal, provided there is sufficient competent evidence in the record to sustain the decree, the reason béing that the court is supposed to have disregarded all evidence in the case except that which is competent and relevant to the issue.
It is also claimed that among the various taxes extended against these lands, is one for the payment of certain bonds which it is alleged are void, and were fraudulently issued. This objection can not prevail. The appellants appeared in the county court and resisted the application for judgment, and should have made their objection to that court. Having personally appeared, and there raised all objections they saw proper to the obtaining of the judgment, and failing to appeal or prosecute a writ of error therefrom, it becomes conclusive *275upon them as to all questions or objections that were or could have been raised against its rendition.
The cases cited by counsel for plaintiffs in error to show that a judgment rendered against land for various taxes, a portion of which is illegal, is for that reason void, does not apply to a case where the party raising the objection was personally before the court rendering the judgment. The court then having jurisdiction over the person and the subject matter, its judgment, until reversed or set aside, is conclusive upon the parties, no matter what errors may have been committed by the court in the rendition of such judgment. Graceland Cemetery Co. v. The People, 92 Ill. 619.
The allegations in the bill, we think, are clearly sufficient to entitle defendants in error to a foreclosure, not only for the taxes and forfeitures incurred for the year 1879 and previous years, but also for the taxes shown by the collector’s books to be due for the year 1880. The law makes the collector’s books prima facie evidence of the taxes due against the land, and the allegation in the bill is, that “the full amount now due upon said lands and lots, as shown upon said collector’s books of the year A. D.-1880, for taxes, penalties, interest and costs, including said forfeitures for the years 1878 and 1879, and accrued taxes for the year A. D. 1880, is the sum of $3687.40, and the amount which was and is a lien upon each tract and lot separately, is shown by said books, and said copy attached, opposite to each tract and lot, separately and respectively, ” and the bill prays that the said tax lien may be foreclosed, etc. This objection was raised at the hearing, and out of abundant caution the counsel for complainants asked leave to amend the bill in that respect, to make the allegation correspond with the proof, but the court refused to allow the amendment to be made. As we think the allegation was already sufficient, there was no error in the refusal; but had it been otherwise, the court should have allowed the amendment to be made.
*276There is error, however, in this decree, for which it will have to be reversed. The decree was for the full amount of taxes, penalties and costs, without allowing plaintiffs in error anything for large sums of money they had paid on these taxes, to the proper officers, under the alleged compromise with the board of supervisors. It was the duty of the court to allow a credit on each tract of land for whatever had been paid thereon, and to have ascertained and found by the decree the amount due upon each tract, and the court, in our opinion, erred in requiring, as it seems by the decree to have done, as a condition to such allowance, that the party interested should pay the balance due. That part of the decree with reference to allowing these credits, is as follows: “If the said defendants or parties interested in said lands and lots shall pay the taxes, interest and penalties and costs for which the same are ordered to be sold, to said collector before said lands are sold, with "costs of suit, then the said, collector shall'allow as a credit all sums paid to said collector heretofore on account of said taxes, if any such have been paid to him. ” To ascertain and fix the amount due on each tract, the court can refer the ease to the master to determine, and report to the court the amount remaining unpaid on each tract, including costs, and the approval of such report by the court would be a sufficient finding by the court as to such amounts. The decree should also fix a short time within which the amount found due should be paid, so that parties interested may pay upon all or any of the tracts, and as to such, avoid the sale.
It is objected that some of the lots were assessed jointly, and not separately, as required by the statute. The presumption should be indulged in favor of the proceedings of the assessor, that the lots were so situated that their value could not be ascertained separately, as, if one building had covered part of both. But in this particular ease plaintiffs in error can not raise that objection here, as they appeared and de*277fended against the judgment. The decree should follow the judgment in that respect, and for the purpose of sale or payment of the taxes, penalties, etc., property thus assessed should be treated as one lot.
It is said the court below erred in rendering judgment against James Mix for costs. We have examined the decree and are unable to find anything said about the costs of this suit. The costs mentioned in the decree are to be made by a sale of the land, unless parties interested shall see proper to pay it with the taxes, penalties, etc., and thus avoid a sale. This is in no sense a judgment against Mix or anybody else, but is against the land. There is no question before us as to the costs of this suit.
It is assigned for cross-error that the court erred in refusing to render a decree for the payment of the State and county taxes, and in dismissing the bill as to them, and all penalties and forfeitures connected therewith. We are of opinion that this assignment of error should be sustained. As we have before said, the proceedings before the board of supervisors in attempting to re-assess these lands and lots and compromise with plaintiffs in error concerning these taxes, was not'only unauthorized, but even if it was, the same has been set aside on certiorari, and for the purposes of this case are to be treated as if they had never taken place, except that such of the parties as have paid any taxes on these lands or lots under said agreement, are entitled to a credit therefor.
It is urged that the land was not assessed in the names of the true owners, and that the county clerk and assessor, though requested to assess the same, refused to do so. We do not see that that is any reason why the owner should not pay the taxes, or why judgment may not be rendered against the land therefor, or the lien created for the same should not be foreclosed. If plaintiffs in error have been injured by the willful and fraudulent misconduct of the clerk or assessor, the law will probably afford them an adequate remedy. Such con*278duct is not a defence to this proceeding. It is said others have an interest in these lands and lots who should be made parties to the suit. If there are any such persons, they, not being made parties, will not be bound by the decree in this case, nor will their interest in the property be affected thereby. But that ought not, so far as we can see, prevent the foreclosure as to the interest of the defendants.
It is also urged, that as to some of the lands or lots the description is so defective that the same can not be located. As to the tracts to which this objection is made, it is replied by counsel for defendants in error that no foreclosure was taken. As the record is voluminous, and the case reversed upon other grounds, we have not taken the pains to make the necessary comparison to ascertain whether this is correct or not. The decree being several as to each tract, if, as to some, the description is void for uncertainty, that would not vitiate the sale or render the decree erroneous as to the other tracts. In this peculiar statutory proceeding the description must necessarily be as set forth in the assessment list and judgment, and a bill to correct it, where it is defective or erroneous, could not, probably, be maintained. We have held, in a direct proceeding for - judgment against lands -for taxes, that there could be no lien, and consequently no judgment, unless they are described so that they can be located and found. (Sanford v. The People, 102 Ill. 374; People v. Chicago and Alton Railroad Co. 96 id. 369.) Whether a party who has personally appeared and objected to the rendition of the judgment, but not on these grounds, can be heard to say that no decree shall be rendered for a sale of the land because of this faulty description, we will not at this time decide. If the description is void for uncertainty, it can not harm the real owner by selling, and yet there might be parties willing, at the foreclosure sale, to purchase the property for the amount of the taxes, penalties and costs, and run the risk of the sufficiency of the description. In this way the revenue might be col*279lected, and we ought not unnecessarily to throw obstacles in the way. While the courts may not be able, in this class of cases, to correct a bad description, it will be time enough to hold it bad when they are obliged to do so. Should counsel for complainants below desire, the court should give them leave to dismiss their bill as to any tracts of land or lots the description of which they are satisfied is void for uncertainty.
There are other minor objections raised by counsel for plaintiffs in error, but none of them are of such a character as would require a reversal of the decree below. Injustice may have been done the plaintiffs in error by too high an assessment of their property, and from the action of the board of supervisors it would seem that such was the ease; but we are powerless to remedy the wrong that may have been done them in this respect.
The decree of the court below is reversed, with directions to that court to ascertain and fix the amount due against each tract of land to be embraced in the decree of foreclosure, and to render such decree in conformity with this opinion.
Decree reversed.
