Ill. Admin. Code tit. 95, § 400.620
a) Definitions. As used in this Section:

e) Burden of Proof. When an appropriate motion or objection has been made by the defense under subsection (d)(2), the prosecution has the burden of establishing the admissibility of the evidence. When a specific motion or objection has been required under subsection (d)(3), the burden on the prosecution extends only to the grounds upon which the defense moved to suppress or object to the evidence.
g) Corroboration. An admission or a confession of the accused may be considered as evidence against the accused on the question of guilt or innocence only if independent evidence, either direct or circumstantial, has been introduced that corroborates the essential facts admitted to justify sufficiently an inference of their truth. Other uncorroborated confessions or admissions of the accused that would themselves require corroboration may not be used to supply this independent evidence. If the independent evidence raises an inference of the truth of some but not all of the essential facts admitted, the confession or admission may be considered as evidence against the accused only with respect to those essential facts stated in the confession or admission that are corroborated by the independent evidence. Corroboration is not required for a statement made by the accused before the court by which the accused is being tried, for statements made prior to or contemporaneously with the act, or for statements offered under a rule of evidence other than that pertaining to the admissibility of admissions or confessions.
