Ill. Admin. Code tit. 56 § 120.560
The Illinois Rules of Evidence shall apply to the extent practicable unless, by such application, the ALJ determines that application of the rule would be an injustice or preclude the introduction of evidence of the type commonly relied upon by a reasonably prudent person in the conduct of his or her affairs. The ALJ must state on the record his or her reasons for that determination. Any objection with respect to the conduct of the hearing, including any objection to the introduction of evidence, may be stated orally, accompanied by a short statement of the grounds for the objection, and included in the record. No objection shall be deemed waived by further participation in the hearing.
