(765 ILCS 721/20)
Sec. 20. Rebuttable presumption. In an action by or against the tenant, if within one year before the alleged act of retaliation there is evidence that the retaliation was against the tenant's conduct that is protected under this Act, that evidence creates a rebuttable presumption that the landlord's conduct was retaliatory. The presumption does not arise if the protected tenant activity was initiated after the alleged act of retaliation.
