A reviewing court, when deciding an appeal from a judgment in an administrative review proceeding, reviews the administrative agency's decision, not the circuit court's decision, and will reverse where the agency's decision is legally erroneous. Masterton v. Village of Glenview Police Pension Board, 2022 IL App (1st) 220307, ΒΆ 45. "Interpretation of a statute is a question of law where the agency's interpretation is considered relevant but not binding on the court."
