Section 1910
Section 1910.63Â Burdens of
Proof
a)Â Â Â Â Â Â Â Â Under the principles of a de novo proceeding, the Property Tax
Appeal Board shall not presume the action of the board of review or the
assessment of any local assessing officer to be correct. However, any
contesting party shall have the burden of going forward.
b)Â Â Â Â Â Â Â Â Under the burden of going forward, the contesting party must
provide substantive, documentary evidence or legal argument sufficient to
challenge the correctness of the assessment of the subject property. Failure to
do so will result in the dismissal of the appeal.
c)Â Â Â Â Â Â Â Â Once a contesting party has provided evidence or argument
sufficient to challenge the correctness of the assessment of the subject
property, the board of review shall be required to go forward with the appeal.
The board of review must provide substantive, documentary evidence or legal
argument sufficient to support its assessment of the subject property or some
other, alternate valuation. Failure to do so will result in a decision by the
Property Tax Appeal Board based upon the information submitted by the
contesting party and, if applicable, the evidence submitted by any intervening
party.
d)Â Â Â Â Â Â Â Â Any intervening party shall be required to support the
position it propounds with substantive, documentary evidence or legal argument
as provided in this Part.
e)Â Â Â Â Â Â Â Â When market value is the basis of the appeal, the value of the
subject property must be proved by a preponderance of the evidence. When
unequal treatment in the assessment process is the basis of the appeal, the
inequity of the assessments must be proved by clear and convincing evidence.
