Ill. Admin. Code tit. 20, § 2900.140
a) The CCLRB will review all objections presented by local law enforcement agencies or the Department. In its review of objections, the CCLRB shall consider only the following information:
2) any material properly submitted by the applicant; and
b) The CCLRB may request additional information from the objecting law enforcement agency, the Department or the applicant.
e) CCLRB will review an objection to determine whether the objection appears sustainable on its face or in light of any information the CCLRB has obtained pursuant to subsection (b) or (c). Within 10 calendar days after determining that an objection appears sustainable, the CCLRB shall send the applicant notice of the objection, including the basis of the objection and the agency submitting the objection. This determination of a sustainable objection is not a final administrative decision of the Board and shall not be reported as such to the Department.
