Illinois General Assembly - Illinois Compiled Statutes

Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

220 ILCS 5/10-105

(220 ILCS 5/10-105) (from Ch. 111 2/3, par. 10-105)

Sec. 10-105.

No person shall be excused from testifying or from producing any
papers, books, accounts or documents in any investigation or inquiry or
upon any hearing ordered by the Commission, when ordered to do so by the
Commission or any commissioner or administrative law judge,
upon the ground that the testimony or evidence, documentary or
otherwise, may tend to incriminate him or subject him to a penalty or
forfeiture. But no person shall be prosecuted or subjected to any penalty
or forfeiture for or on account of any transaction, matter or thing
concerning which he may testify or produce evidence, documentary or
otherwise, before the Commission or a commissioner or administrative law judge:
Provided, that such immunity shall extend only to a natural person, who in
obedience to a subpoena, gives testimony under oath or produces evidence,
documentary or otherwise under oath. No person so testifying shall be
exempt from prosecution and punishment for perjury committed in so testifying.
The Commission or a commissioner or administrative law judge
 may, on the motion of a party or on its own
motion, strike, in whole or in part, the testimony of a person who is not
reasonably
prepared to respond to questions under cross-examination intending to elicit
information directly related to matters raised by that person in his
testimony.
