89 Ill. Adm. Code 270.446
Witness Testimony
Section 270.446 Witness Testimony
a) The ALJ
may exercise reasonable control over the form of the examination and order of
witnesses so as to make the examination effective for gathering the facts,
avoiding delay, and protecting witnesses from harassment or undue
embarrassment. The ALJ may limit the examination of witnesses to prevent
cumulative or irrelevant evidence.
b) Before
testifying, a witness shall declare by oath or affirmation and under penalty of
perjury that he or she will testify truthfully.
c) Any
individual is competent to testify as a witness so long as he or she is capable
of understanding the nature of an oath or affirmation and giving an accurate
account of facts within the witness' personal knowledge. In the absence of
contrary evidence, a witness is presumed competent to testify. The ALJ determines
competency of a witness.
d) A
witness may appear voluntarily to testify or may testify under power of a
subpoena issued by the Department/other entity under Section 270.440.
e) A
witness compelled to testify in response to a subpoena may be accompanied and
advised by an attorney.
f) A
witness may testify as to facts within the witness' personal knowledge. A
witness not qualified as an expert pursuant to Section 270.448 may only provide
opinion testimony if the opinion is rationally based on the perception of the
witness and helpful to a clearer understanding of the witness' testimony or a
determination of the issues.
g) Any
party may request to call any individual as a witness and conduct direct
examination. Except for preliminary matters and facts already in evidence,
questions on direct examination should be open-ended, non-leading questions.
h) The
opposing party is entitled to cross-examine any witness. A witness may be
cross-examined on any matter relevant to any issue in the case, including
credibility. In the interests of justice, the ALJ may limit testimony on
cross-examination to subject matters testified about on direct examination.
i) A
party may be allowed to examine an adverse witness as if under
cross-examination.
j) The ALJ
may question any witness pursuant to Section 270.452(g)(6).
k) If a
witness uses a document to refresh memory for the purpose of testifying, either
while testifying or before testifying, the ALJ may have the witness show the
document to the opposing party and be cross-examined about the document.
l) In
the interests of justice, at the request of a party, or an ALJ's own motion,
the ALJ may order witnesses excluded so that they cannot hear the testimony of
other witnesses.
m) The ALJ
may direct that all excluded or non-excluded witnesses be kept separate until
called and may prevent them from communicating with one another until they have
been examined or the hearing is ended.
