Rebuttal Evidence
Section 1910
Section 1910.66 Rebuttal Evidence
a) Upon first
receipt of the argument and accompanying documentation filed by an opposing
party, any other party may, within 30 days after the date of the Board's notice:
1) For
appeals filed for assessment years prior to 2016, file two copies of written or
documentary rebuttal evidence for appeals with a request for a change in
valuation of less than $100,000 or submit three copies of written or
documentary rebuttal evidence for appeals with a request for a change in
valuation of $100,000 or more.
2) For
appeals beginning with the 2016 assessment year and each year thereafter, file
one copy of written or documentary rebuttal evidence, unless the rebuttal
evidence exceeds 500 total pages, in which case, all written and documentary
rebuttal evidence must be submitted in triplicate.
3) Except
as provided in Sections 1910.40 and 1910.60, any party shall have 30 days after
first receipt of the argument and written documentary evidence filed by an
opposing party to file written or documentary evidence in rebuttal. Rebuttal
evidence shall consist of written or documentary evidence submitted to explain,
repel, counteract or disprove facts given in evidence by an adverse party and
must tend to explain or contradict or disprove evidence offered by an adverse
party. Rebuttal evidence shall include a written factual critique based on
applicable facts and law, a review appraisal, or an analysis of an adverse
party's appraisal prepared by a person who is an expert in the appraisal of
real estate. This written critique, review appraisal, or analysis must be
submitted within the responding party's 30-day rebuttal period pursuant to this
Section.
b) In
any appeal in which a change in assessed valuation of $100,000 or more is
sought, the Board shall grant one 30-day extension of time to submit rebuttal
evidence upon good cause shown in writing. Good cause shall include the
complexity of the appeal, the volume of the evidence submitted by an opposing
party, and the inability of a rebuttal appraiser to complete the review and
written critique within the 30-day filing period. A request for an extension
of time to submit rebuttal evidence shall be in writing, supported by
affidavit, and served on the Board and all other parties to the appeal. No
further extensions to submit rebuttal evidence shall be granted.
c) Rebuttal
evidence shall not consist of new evidence such as an appraisal or newly
discovered comparable properties. A party to the appeal shall be precluded
from submitting its own case in chief in the guise of rebuttal evidence.
