35 ILCS 1010/1-67

Temporary suspension of proceedings.

(a) If any party to a proceeding pending in the Tax Tribunal is also a defendant in a criminal case pending in any court in this State involving the same conduct as the case before the Tax Tribunal, then, upon motion of any party or the Attorney General, or upon its own motion, the Tax Tribunal shall enter an order staying the proceeding.

(b) If the Attorney General or the Department determines that the interests of justice so require, either may file an ex parte motion with the Chief Administrative Law Judge requesting that any proceeding pending before the Tax Tribunal be stayed. If the Chief Administrative Law Judge finds that the motion reasonably shows that the proceeding may interfere with an ongoing criminal investigation, the Chief Administrative Law Judge shall enter an order staying the proceeding. The denial of a motion to enter an order staying the proceeding is a final administrative decision within the meaning of Section 3-101 of the Administrative Review Law and may be reviewed by the Circuit Court pursuant to the Administrative Review Law.
