70.64 - Review of equalized values.

70.64 Review of equalized values.
(1) By tax appeals commission. The assessment and determination of the relative value of taxable general property in any county or taxation district, made by the department of revenue under s. 70.57, may be reviewed, and a redetermination of the value of such property may be made by the tax appeals commission, upon appeal by the county or taxation district. The filing of such appeal in the manner provided in this section by any county or taxation district shall impose upon the commission the duty, under the powers conferred upon it by s. 73.01 (4) (a), to review the assessment complained of. If, in its judgment based upon the testimony, evidence and record made on the preliminary hearing of such appeal, the commission finds such assessment to be unequal and discriminatory, it shall determine to correct such assessment to bring it into substantial compliance with law. Except as provided in this section, the appeal shall be taken and such review and redetermination shall be made as provided in ss. 73.01 and 73.015 and under the rules governing the procedure of the commission.
(2) Authorization of appeals. To authorize such appeal an order or resolution directing the same to be taken shall be adopted by the governing body of the county or taxation district taking the appeal at a lawful meeting of the governing body. When an appeal shall have been authorized the prosecution of it shall be in charge of the chairperson of the county board or county administrator or of the chairperson, mayor or president of the taxation district taking the appeal unless otherwise directed by the governing body. The officers or committee in charge of the appeal may employ attorneys to conduct the appeal. After authorizing an appeal as provided in this subsection, any 2 or more taxation districts in the same county may join in taking and prosecuting an appeal.
(3) Form of appeal. To accomplish an appeal there shall be filed with the tax appeals commission on or before October 15 an appeal in writing setting forth:
(a) That the county or taxation district, naming the same, appeals to the tax appeals commission from the assessment made by the department of revenue under s. 70.57, specifying the date of such assessment.
(b) Whether the appeal is to obtain a review and redetermination of the assessment of all the taxation districts of the county or of particular districts only, therein specified.
(c) Whether review and redetermination is desired as to real estate, or personal property, or both.
(d) That the appeal has been authorized by an order or resolution of the county board or governing body of the taxation district in whose behalf the appeal is taken.
(e) A plain and concise statement, without unnecessary repetition, of the facts constituting the grievance sought to be remedied upon appeal, which shall specifically allege in what respects the assessment is in error.
(f) The appeal shall be verified by a member of the governing body of the county or taxation district authorizing the appeal in the manner that pleadings in courts of record are verified. When 2 or more taxation districts join in taking such appeal the verification may be made by the proper officer of any one of them.
(4) Certified copies. Upon the filing of such appeal, the clerk of the county or taxation district, without delay, shall prepare certified copies of it, together with certified copies of the value established by the department of revenue from which the appeal is taken and a complete list showing the clerk of each taxation district within the county and the post-office address of each. The clerk shall mail by certified mail 4 sets of certified copies to the tax appeals commission and one set of the copies to the department of revenue, the county clerk and the clerk of each taxation district within the county.
(5) Appearance. Not later than 30 days after the clerk of the county or taxation district has mailed the certified copies, unless the time is extended by order of the tax appeals commission, any county, town, city or village may cause an appearance to be entered in its behalf before the commission in support of the appeal and uniting with the appellant for the relief demanded; and by verified petition or statement showing grounds therefor may apply for other or further review and redetermination than that demanded in the appeal. Within the same time the county, town, city or village in the county may in the same manner have its appearance entered in opposition to the appeal and to the relief demanded. Such appearances shall be authorized in the manner for authorizing an appeal under sub. (2). When so authorized the interests of the county, town, city or village authorizing it shall be in the charge of the chairperson, mayor or president thereof unless otherwise directed by the body authorizing such appearance; and attorneys may be employed in that behalf. In such appearances any 2 or more of the towns, cities and villages of the county may join if united in support of or in opposition to the appeal. Four copies of each appearance, petition or statement mentioned in this subsection shall be filed in the offices of the tax appeals commission and a copy of each mailed by certified mail to the department of revenue, to the county clerk, and to the clerk of each town, city and village within the county, and a copy to the attorney authorized to appear on behalf of the county or any town, city or village within the county.
(6) Hearing. As soon as practicable, the commission shall set a time and place for preliminary hearing of such appeal. At least 10 days before the time set for such hearing, the commission shall cause notice thereof to be mailed by certified mail to the county clerk and to the attorney or the clerk of each town, city and village in whose behalf an appearance has been entered in the matter of such appeal, and to the clerk of each town, city or village which has not appeared, and mail a like notice to the clerk of the taxation district taking such appeal and to the department of revenue. The department of revenue shall be prepared to present to the commission at such time during the course of the hearings as the commission requires, the full value of all property subject to general property taxation in each town, village and city of the county, as determined by the department according to s. 70.57 (1) or in the case of a complaint by a taxation district under a county assessor such information as the department has in its possession. Said hearing may be adjourned, in the discretion of the tax appeals commission, as often and to such times and places as may be necessary in order to determine the facts. If satisfied that no substantial injustice has been done in the taxation district assessment appealed from, the commission in its discretion may dismiss such appeal. If satisfied that substantial injustice has been done in the taxation district assessment, the commission shall determine to revalue any or all of the taxation districts in the county, which it deems necessary, in a manner which in its judgment is best calculated to secure substantial justice.
(7) Redetermination. The commission shall then proceed to redetermine the value of the taxable general property in such of the taxation districts in the county as it deems necessary. It may include in such redetermination other taxation districts than first determined upon and may include all of the taxation districts in said county, if at any time during the progress of its investigations or revaluations it is satisfied that such course is necessary in order to accomplish substantial justice and to secure relative equality as between all the taxation districts in such county. It shall make careful investigation of the value of taxable general property in the several taxation districts to which such review and redetermination shall extend, in any manner which in its judgment is best calculated to obtain the fair, full value of such property. The commission may employ such experts and other assistants as may be necessary, and fix their compensation. In making such investigations the commission and all persons employed therein by the commission shall have all the authority possessed by assessors so far as applicable, including authority to administer oaths and to examine property owners and witnesses under oath as to the quantity and value of the property subject to assessment belonging to any person or within any taxation district to which the investigation shall extend.
(8) Hearing. The commission may at any time before its final determination appoint a time and place at which it will hear evidence and arguments relevant to the matters under consideration upon such appeal. The time to be devoted to such hearings may be limited as the commission directs. At least 10 days before the time fixed for such hearings, the commission shall cause notice thereof to be mailed by certified mail to the county clerk and to the attorney or other representative of each town, city and village in whose behalf an appearance has been entered in the matter of such appeal, and a like copy to the department of revenue.
(9) Testimony. The tax appeals commission may take testimony. Witnesses summoned at the instance of said commission shall be compensated at the rates provided by law for witnesses in courts of record, the same to be audited and paid the same as other claims against the state, upon the certificate of said commission. If any property owner or other person makes any false statement to said commission or to any person employed by it upon any matter under investigation that person shall be subject to all the forfeitures and penalties imposed by law for false statements to assessors and boards of review.
(10) Determination. The tax appeals commission shall make its determination upon such appeal without unreasonable delay and shall file a copy thereof in the office of the county clerk and mail by certified mail a like copy to the department of revenue and to the clerk and attorney of the taxation district appealing, and a copy to the clerk and attorney of each taxation district having appeared. In such determination the commission shall set forth the relative value of the taxable general property in each town, city and village of such county as found by them, and what sum, if any, shall be added to or deducted from the aggregate value of taxable property in each such taxation district as fixed in the determination of the department of revenue from which such appeal was taken in order to produce a relatively just and equitable taxation district assessment. Such determination shall be final.
(11) Computation. The determination of the commission shall not affect the validity of taxes apportioned in accordance with the taxation district assessment from which such appeal was taken; but if it is determined upon such appeal that such taxation district assessment is relatively unequal, such inequality shall be remedied and compensated in the apportionment of state and county taxes in such county next following the determination of said commission in the following manner: Each town, city and village whose valuation in such taxation district assessment was determined by said commission to be relatively too high shall be credited a sum equal to the amount of taxes charged to it upon such unequal assessment in excess of the amount equitably chargeable thereto according to the determination of the commission; and each town, city and village whose valuation in such taxation district assessment was determined by said commission to be relatively too low shall be charged, in addition to all other taxes, a sum equal to the difference between the amount charged thereto upon such unequal assessment and the amount which should have been charged thereto according to the determination of the commission. The department of revenue shall aid the county clerk in making proper computations.
(12) Expenses. The tax appeals commission shall transmit to the county clerk with its determination on such appeal a statement of all expenses incurred therein by or at the instance of the commission, which shall include the actual expenses of the commission and regular employees of the commission, the compensation and actual expenses of all other persons employed by it and the fees of officers employed and witnesses summoned at its instance. A duplicate of such statement shall be filed in the office of the department of administration. Such expenses shall be audited upon the certificate of the commission, and paid out of the state treasury, in the first instance, as other claims against the state are audited and paid. The amount of such expenses shall be a special charge against such county and shall be included in the next apportionment and certification of state taxes and charges, and collected from such county, as other special charges are certified and collected. Unless otherwise directed by the commission in its determination upon such appeal, the county clerk, in the next apportionment of state and county taxes, shall apportion the amount of such special charges to and among the towns, cities and villages in such county whose relative valuations were increased in the determination of the commission in proportion to the amount of such increase in each of them respectively. The apportionment of such expenses shall be set forth in the determination of the commission. The amount so apportioned to each such town, city and village shall be charged upon its tax roll and shall be collected and paid over to the county treasurer as other state taxes and special charges are collected and paid.
(13) Procedures. The provisions of s. 73.01, insofar as consistent with this section, shall be applicable to proceedings under this section.
