If no rule has been promulgated by the Commission on a particular type of discovery, the Code of Civil Procedure may be considered persuasive authority. The types of discovery shall be the same as in civil cases in the circuit courts of this State, provided, however, that a party may take discovery depositions only upon leave of the hearing officer and for good cause shown. The Department and the respondent shall be parties in hearings under this Article. The Department shall seek appropriate relief for the complainant and vindication of the public interest. Any complainant may intervene as a party.
All parties have the right to examine and cross examine witnesses.
The testimony taken at the hearing shall be under oath or affirmation and a transcript shall be made and filed in the office of the Commission. The testimony taken at the hearing is subject to the same rules of evidence that apply in courts of this State in civil cases. Compelling Appearance of Parties at Hearing. The appearance at the hearing of a party or a person who at the time of the hearing is an officer, director, or employee of a party may be required by serving the party with a notice designating the person who is required to appear. The notice also may require the production at the hearing of documents or tangible things.
