14 Ill. Adm. Code 200.407
Rules of Evidence in Hearings
Section 200
Section 200.407 Rules of
Evidence in Hearings
a) Irrelevant, immaterial or unduly repetitious evidence shall be
excluded. The rules of evidence and privilege as applied in civil cases in the
Circuit Courts of this State shall be followed. However, evidence not
admissible under such rules of evidence may be admitted (except where precluded
by statute) if it is of a type commonly relied upon by reasonably prudent
persons in the conduct of their affairs. Objection to evidentiary offers may
be made and shall be noted in the record. Subject to these requirements, when
a hearing will be expedited and the interests of the parties will not be
prejudiced, any part of the evidence may be received in written form.
b) Subject to the evidentiary requirements of subsection (a) of
this Section, a party may conduct cross-examinations required for a full and
fair disclosure of the facts.
c) Notice may be taken of matters of which the Circuit Courts of
this State may take judicial notice. Parties shall be notified either before
or during the hearing, or by reference in preliminary reports or otherwise, of
the material noticed, including any staff memoranda or data, and they shall be
afforded an opportunity to contest the material so noticed.
