5 ILCS 855/30
If the court finds by a preponderance of the evidence that a law enforcement agency obtained household electronic data pertaining to a person or his or her effects in violation of this Act, then the information shall be presumed to be inadmissible in any judicial or administrative proceeding. The State may overcome this presumption by proving the applicability of a judicially recognized exception to the exclusionary rule of the Fourth Amendment to the United States Constitution or Section 6 of Article I of the Illinois Constitution, or by a preponderance of the evidence that the law enforcement officer was acting in good faith and reasonably believed that one or more of the exceptions identified in Section 15 existed at the time the household electronic data was obtained.
