Hearings on appeal

# (1)

At the hearing upon a petition, the assessor or the assessor's authorized representative shall be present and shall produce information to support the basis and amount of the assessor's valuation of the property. The board shall hear and consider all testimony and examine all exhibits produced or introduced by either the petitioner or the assessor, with no presumption in favor of any pending valuation, and may subpoena witnesses to testify. The costs of producing the petitioner's witnesses shall be paid by the petitioner, and the costs of producing the assessor's witnesses shall be paid by the county. On the basis of the testimony produced and the exhibits introduced, the board shall grant or deny the petition, in whole or in part, and shall notify the petitioner and the assessor in writing. If the board denies the petition, in whole or in part, such written notice shall inform the petitioner of the right to appeal within the thirty-day period following the denial to the district court or the board of assessment appeals pursuant to the provisions of section 39-8-108 (1) or within the thirty-day period following the denial to submit the case to arbitration pursuant to the provisions of section 39-8-108.5. Such notice shall state that, if the appeal is to the board of assessment appeals, the hearing before the board of assessment appeals shall be the last hearing at which testimony, exhibits, or any other type of evidence may be introduced by either party and that, if there is an appeal to the court of appeals pursuant to section 39-8-108 (2), the record from the hearing before the board of assessment appeals and no new evidence shall be the basis for the court's decision. The phone number and address of the board of assessment appeals shall also be included on the notice. The notice shall also state, in general terms, how to pursue arbitration and that, if a taxpayer submits the case to arbitration, the decision reached under such process shall be final and not subject to review. If a referee heard the case, the board shall, at the written request of any taxpayer or any agent of such taxpayer within seven working days after receipt of said request, make available to the taxpayer or agent the referee's findings and recommendations. At the board's election, the board may either mail, fax, or send by electronic transmission such findings and recommendations to the address, phone number, or electronic address supplied by said taxpayer or agent. Upon receipt of such request, the board shall notify the taxpayer or agent of the estimated cost of providing such findings and recommendations, payment of which shall be made prior to providing such findings and recommendations. Upon providing such findings and recommendations, the board may include a bill for the reasonable cost above the estimated cost and up to the statutory maximum which shall be due and payable upon receipt by the taxpayer or agent.

(I) On and after August 10, 2011, in addition to any other requirements under law, any petitioner appealing either a valuation of rent-producing commercial real property to the board of assessment appeals pursuant to section 39-8-108 (1) or a denial of an abatement of taxes pursuant to section 39-10-114 shall provide to the county board of equalization or to the board of county commissioners of the county in the case of an abatement, and not to the board of assessment appeals, the following information, if applicable:

(II) The petitioner shall provide the information required by subsection (5)(a)(I) of this section within ninety days after the appeal has been filed with the board of assessment appeals; except that a petitioner who has already provided information to an assessor in accordance with section 39-5-122 (2.5) is not required to provide any additional information under this subsection (5)(a).

# (b)

(I) The assessor, the county board of equalization, or the board of county commissioners of the county, as applicable, shall, upon request made by the petitioner, provide to a petitioner who has filed an appeal with the board of assessment appeals not more than ninety days after receipt of the petitioner's request, the following information: (A) The primary method used by the county to determine the value of the subject property; and (B) The rates used by the county to determine the value of the subject property under the method identified in accordance with subsection (5)(b)(I)(A) of this section.

If a petitioner fails to provide the information required by subparagraph (I) of paragraph (a) of this subsection (5) by the deadline specified in subparagraph (II) of said paragraph (a), the county may move the board of assessment appeals to compel disclosure and to issue appropriate sanctions for noncompliance with such order. The motion may be made directly by the county attorney and shall be accompanied by a certification that the county assessor or the county board of equalization has in good faith conferred or attempted to confer with such petitioner in an effort to obtain the information without action by the board of assessment appeals. If an order compelling disclosure is issued under this paragraph (c) and the petitioner fails to comply with such order, the board of assessment appeals may make such orders in regard to the noncompliance as are just and reasonable under the circumstances, including an order dismissing the action or the entry of a judgment by default against the petitioner. Interest due the taxpayer shall cease to accrue as of the date the order compelling disclosure is issued, and the accrual of interest shall resume as of the date the contested information has been provided by the taxpayer.
