Section 1910
Section 1910.68Â Subpoenas
a)Â Â Â Â Â Â Â Â Issuance. Â Upon written request by a party to an appeal, the
Chairman of the Board or his designee may issue a subpoena, as authorized by
Section 16-175 of the Code, for the attendance of a witness or the production
of books, records, correspondence, documents, papers or other evidence to
facilitate the determination of the correct assessment of any parcel of real
property.  Requests for subpoenas may be made by any party. The request for
the issuance of a subpoena to the property owner or taxpayer shall incorporate
a showing by affidavit from a designated appraiser or county assessing official
that such subpoena is reasonably required to obtain information that cannot be
obtained elsewhere by the exercise of due diligence or through requests for
information and is necessary to obtain information essential to derive an
estimate of value of the real property under appeal. A request for a subpoena
to compel the attendance of a witness shall contain the name, address and
telephone number of the witness to be subpoenaed and the docket number of the
Board appeal. A request for a subpoena duces tecum shall specify the books,
records or other documents to be produced and the material facts to be proved
by them. A request for a subpoena shall be served at the same time on the
party from whom testimony or documents are sought, accompanied with proof of
service, and filed with the Board's Springfield office. Â In ruling on a subpoena
request, the Board shall consider the reasonableness of the demand and whether
the requested documents are relevant and necessary to derive an estimate of the
value of the real property under appeal.
b)Â Â Â Â Â Â Â Â Service and Contents. Â Subpoenas shall be served by any person
lawfully authorized to serve a subpoena under the laws of this State. (See Section
16-175 of the Code.) Â The party requesting the subpoena shall be responsible
for its service. Â A subpoena shall be served reasonably in advance of its return
date. Â The subpoena shall state the name and address of the person initiating
its issuance and the person to whom and the place, date, and the time at which
it is returnable. The party requesting the subpoena shall serve the subpoena
on any witness at least 7 days before the scheduled hearing date before the
Board.
c)Â Â Â Â Â Â Â Â Response to Subpoena Request. Within 21 days after receipt of
a request for a subpoena on any person or for documents, the subpoenaed party
may file a response challenging the issuance of the subpoena, stating reasons
in support of the relief. Â A copy of the response shall be served at the same
time on the person requesting the subpoena, accompanied by proof of service,
and on the Board.
d)Â Â Â Â Â Â Â Â Fees
. Â Witnesses attending any proceeding held by the
Property Tax Appeal Board pursuant to any subpoena shall be paid the same fees
and mileage that are paid witnesses in the circuit courts of this State.
(Section
16-175 of the Code)Â The cost of service and witness and mileage fees shall be
paid by the party requesting the subpoena.
e)Â Â Â Â Â Â Â Â Â Enforcement.
 Whenever any person knowingly fails or refuses to comply with a subpoena
served in accordance with this Section, the party serving the subpoena or the
Board shall petition the appropriate circuit court for an order enforcing the
subpoena.
f)Â Â Â Â Â Â Â Â Confidential
Information. If a subpoena is issued for documents or other information under
this Section, a party may petition the Board for an order protecting the
confidentiality of any confidential information contained within those
documents or other information. A request for a protective order under this
subsection shall identify the confidential information and explain the reasons
for the requested protective order. Upon finding that the requested documents
or other information contain confidential information, the Board shall issue a
protective order:
1)Â Â Â Â Â Â Â Â requiring
the parties to maintain the confidentiality of documents or other information
produced;
2)Â Â Â Â Â Â Â Â requiring
that the documents be filed under seal; and
3)Â Â Â Â Â Â Â Â taking
any other steps necessary to protect against disclosure of confidential
information.
