PRESIDING JUSTICE MASON delivered the judgment of the court, with opinion.
¶ 1 Respondent-appellant Edward OConnor was removed from a list of eligible candidates for a position as a Chicago police officer based on his admission that he had twice been arrested for domestic battery in 2003 and 2014. Following a hearing on his removal, he was reinstated to the eligibility list by respondent Human Resources Board of the City of Chicago (Board). Petitioners-appellees Eddie Johnson, the Chicago Police Department (CPD) superintendent, and the City of Chicago (petitioners) petitioned for a common law writ of certiorari in the circuit court to review the Boards decision. The court reversed the decision of the Board, and OConnor appeals. For the reasons that follow, we affirm and remand with directions.
¶ 2 BACKGROUND
¶ 3 In 2014, OConnor applied for a position as a probationary police officer with the CPD. Part of the application process required completing a personal history questionnaire, in which OConnor admitted that he had been arrested for domestic battery against his mother in 2003, when he was 18, and against his roommate and ex-girlfriend in 2014.
¶ 4 OConnor wrote that in 2003 he was living with his mother, a retired police officer. One morning, his mother woke him up and asked him to do chores, but he said no because he had to leave for work and told her he would do them when he returned. According to OConnor, his mother yelled at him, and he repeated his refusal to do the chores and slammed the door in her face, whereupon his mother had him arrested for domestic violence. OConnors narrative with regard to the 2014 incident indicated that his roommate became enraged after he declined to take her to the grocery store and threatened to ruin his life by hitting herself and telling the police that he did it. OConnor laughed and walked away, and his roommate then called the police saying OConnor hit her, when in fact she hit herself with an object she found next to the parking lot of OConnors apartment. The police arrived and arrested OConnor, disbelieving his claim that his roommate injured herself.
¶ 5 An administrative special order (Special Order) by the CPD provides that [a]ny conduct demonstrating a propensity for violence may be grounds for disqualification. Such conduct includes battery and domestic violence. Based on this Special Order, and following a background investigation in which the CPD obtained police reports of the arrests, Investigator Stanley Golucki recommended that OConnor be disqualified for the position of police officer. The CPD accepted the recommendation and advised the Department of Human Resources (DHR) to remove OConnor from the list of eligible candidates.
¶ 6 On June 26, 2015, DHR notified OConnor of his removal from the list but informed him that he could challenge the removal by requesting a hearing with the Board, which he did. At the hearing, which was held on December 16, 2015, Golucki, OConnor, OConnors mother, Karen OConnor, and OConnors girlfriend, Tanya Dovichi, all testified. Golucki testified to the contents of the arrest report of the 2003 incident, which was also made part of the record. The 2003 arrest report indicated that when police arrived at Karens house, she told them that she and OConnor engaged in a verbal dispute after she asked him for help around the house. OConnor grabbed Karen by the neck and threw her to the kitchen floor, causing her injury. Karen declined treatment and to have photos taken of her neck, which the report described as reddened. OConnor freely stated that he didnt grab [Karen] that hard. The officers took OConnor into custody and advised Karen of the upcoming court date. OConnor was charged with domestic battery, but the charge was ultimately stricken with leave to reinstate.
¶ 7 Karen testified that one morning when OConnor was about 17 or 18 years old and living with her, she woke him up to ask for his help in moving something. When OConnor did not get out of bed, Karen took his car keys and told him to walk to work. This prompted OConnor to get out of bed and follow Karen to the kitchen, where he grabbed the keys out of Karens hand. During the struggle with the keys, Karen slipped and fell. She denied that OConnor threw her to the floor or that he choked her. Karen testified that she called the police to teach [OConnor] a lesson not to put his hands on her. On cross-examination, Karen testified that she was surprised the police report indicated that OConnor grabbed her by the neck and threw her to the floor. She was also surprised that the report described her as having a reddened neck.
¶ 8 In his testimony, OConnor agreed with his mothers description of the 2003 incident. He clarified that when he went to the kitchen to retrieve the keys, his mother had her back to him and was holding the keys in her fist, but the lanyard attached to the key ring was free. OConnor approached Karen from behind and grabbed the lanyard to pull the keys from her hands. According to OConnor, Karen then bumped him and he started to fall backwards while still holding the lanyard, which caused Karen to fall down. OConnor denied choking Karen, throwing her to the ground, or punching her. He testified that he learned a lesson, and the charges were dismissed.
¶ 9 The hearing officers report found that it was more likely than not that OConnor engaged in domestic battery against his mother in 2003, but that it was not more likely than not that OConnor committed domestic battery in 2014. The hearing officer concluded that although one instance of domestic battery was shown more likely than not, it occurred 13 years ago when [OConnor] was a teen; once [sic ] instance alone does not show a propensity. Accordingly, the hearing officer recommended to the Board that the decision of the CPD be reversed and OConnors name be returned to the eligibility list.
¶ 10 In July 2016, the Board adopted the hearing officers findings and recommendations in their entirety and reinstated OConnor to the eligibility list.
¶ 11 Johnson petitioned the circuit court for a common law writ of certiorari. Following briefing and oral argument, the court reversed the decision of the Board holding that the hearing officers conclusion that a single violent incident is insufficient to demonstrate a propensity for violence was inconsistent with the language of the Special Order. OConnor timely appeals.
¶ 12 ANALYSIS
¶ 13 At issue in this case is the Boards decision to reinstate OConnor to the eligibility list notwithstanding that he more likely than not committed domestic battery against his mother in 2003. The parties do not dispute that the circuit court properly reviewed the Boards decision pursuant to a common law writ of certiorari , given that the act conferring power on the Board does not expressly adopt the Administrative Review Law ( 735 ILCS 5/3-101 et seq. (West 2016) ) and does not provide for another form of review. See Applegate v. Department of Transportation , 335 Ill. App. 3d 1056, 1061, 270 Ill.Dec. 521, 783 N.E.2d 96 (2002). Our review of a writ of certiorari is essentially the same as our review of a petition filed under the Administrative Review Law. Outcom, Inc. v. Illinois Department of Transportation , 233 Ill. 2d 324, 337, 330 Ill.Dec. 784, 909 N.E.2d 806 (2009). In either case, we review the decision of the agency rather than the circuit court under our traditional standards of review of administrative decisions. Porter v. Illinois State Board of Education , 2014 IL App (1st) 122891, ¶ 25, 379 Ill.Dec. 347, 6 N.E.3d 424.
¶ 14 The applicable standard of review of the agency decision depends on the question presented on appeal. Id. ¶ 26. If the question is one of fact, we apply a manifest weight of the evidence standard, while if the question is one of law, we review the decision de novo. Beggs v. Board of Education of Murphysboro Community Unit School District No. 186 , 2016 IL 120236, ¶ 50, 410 Ill.Dec. 902, 72 N.E.3d 288. And if the appeal presents a mixed question of law and fact, it is subject to review under the deferential clearly erroneous standard. Id. Here, OConnor urges us to apply a clearly erroneous standard to what he contends was a mixed question of law and fact, while Johnson maintains that our review is de novo , arguing the issue on appeal is solely a question of law.
¶ 15 At the outset, we note that OConnor did not advocate for application of the clearly erroneous standard in the circuit court and instead argued that the Boards decision was subject to review under a manifest weight of the evidence standard as it was a question of fact and fact alone. As Johnson points out, a party waives any argument he fails to present in circuit court. Robinson v. Toyota Motor Credit Corp. , 201 Ill. 2d 403, 413, 266 Ill.Dec. 879, 775 N.E.2d 951 (2002). But because waiver is a limitation on the parties and not the court ( Committee for Educational Rights v. Edgar , 174 Ill. 2d 1, 11, 220 Ill.Dec. 166, 672 N.E.2d 1178 (1996) ), we nevertheless address the merits of the parties dispute regarding the standard of review.
¶ 16 A mixed question of law and fact examines the legal effect of a given set of facts or, stated differently, whether uncontested facts satisfy the statutory standard. Comprehensive Community Solutions, Inc. v. Rockford School District No. 205 , 216 Ill. 2d 455, 472, 297 Ill.Dec. 221, 837 N.E.2d 1 (2005). OConnor contends that the issue on appeal is whether the uncontested facts of his 2003 arrest implicate the Special Order so as to justify his disqualification. But that determination turns, in the first instance, on the interpretation of the Special Order, which is a question of law. See Burris v. Department of Children & Family Services , 2011 IL App (1st) 101364, ¶ 30, 351 Ill.Dec. 538, 951 N.E.2d 1202 (interpretation of agency regulation is a question of law). And as discussed supra ¶ 14, we review an agencys decision on questions of law de novo. See Beggs , 2016 IL 120236, ¶ 50, 410 Ill.Dec. 902, 72 N.E.3d 288. Importantly, however, an agencys interpretation of its own rules and regulations enjoys a presumption of validity. (Internal quotation marks omitted.) Burris , 2011 IL App (1st) 101364, ¶ 30, 351 Ill.Dec. 538, 951 N.E.2d 1202 (quoting Walk v. Department of Children & Family Services , 399 Ill. App. 3d 1174, 1181, 339 Ill.Dec. 298, 926 N.E.2d 773 (2010) ).
¶ 17 We construe administrative regulations according to the same standards governing the construction of statutes.
People v. Bonutti , 212 Ill. 2d 182, 188, 288 Ill.Dec. 131, 817 N.E.2d 489 (2004). The fundamental rule of statutory construction is to ascertain and give effect to the legislatures intent. Hayashi v. Illinois Department of Financial & Professional Regulation , 2014 IL 116023, ¶ 16, 388 Ill.Dec. 878, 25 N.E.3d 570. The most reliable indicator of the legislative intent is the plain language of the statute, which must be given its ordinary meaning. Id. Where the language is clear and unambiguous, we may not depart from that language by reading into the statute exceptions, limitations, or conditions that the legislature did not express. Id. With these principles in mind, we turn to an examination of the Special Order.
¶ 18 The Special Order at issue is titled Pre-Employment Disqualification Standards for Applicants for the Position of Police Officer, and the relevant subsection of the Special Order is titled Disqualification Based on Criminal Conduct. Prior to listing the types of criminal conduct that disqualify a candidate, there is a disclaimer which reads: The Standards are as comprehensive as possible, however as noted above, they cannot encompass every possible scenario. * * * Commission of any criminal or quasi-criminal act may result in disqualification from employment as a Police Officer if it is determined that the acts or omissions of the applicant make him or her unsuitable for the position of Police Officer. Here, OConnor was disqualified based on subsection (B)(2)(c) of the Special Order, which reads:
Conduct Indicating Violent Tendencies. Any conduct demonstrating a propensity for violence may be grounds for disqualification. Conduct demonstrating a propensity for violence includes but is not limited to, conduct which would constitute * * * battery * * * [and] domestic violence * * *. As noted above, an applicant who has engaged in any act falling within the scope of this section that constitutes a felony will be found unsuitable for employment. An applicant who has engaged in any act falling within the scope of this section that constitutes a misdemeanor within the last three (3) years (from the date of [personal history questionnaire] submission) or more than one (1) time in his or her life, will be found unsuitable for employment.
¶ 19 The plain language of subsection (B)(2)(c) of the Special Order defines both when disqualification is discretionary as well as when it is mandatory. The first sentence of the order provides that an applicant may be disqualified for any conduct demonstrating a propensity for violence. The word may indicates that the decision to disqualify a candidate for conduct demonstrating a propensity for violence is within the CPDs discretion. See People v. Garstecki , 234 Ill. 2d 430, 443, 334 Ill.Dec. 639, 917 N.E.2d 465 (2009) (statutes use of the word may indicates that a rule is permissive). This is particularly true when we consider that the remaining sentences of the order specify the circumstances under which an applicant will be found unsuitable for employment, i.e. , if the act charged constitutes a felony or if it was a misdemeanor committed (i) within the past 3 years or (ii) more than once in an applicants life. See Hoffman v. Altamore , 352 Ill. App. 3d 246, 256, 287 Ill.Dec. 340, 815 N.E.2d 984 (2004) ([W]hen the legislature uses certain words in one instance and different words in another, different results are intended.).
¶ 20 Our conclusion finds additional support in the fact that the Special Order expressly states that the standards for disqualification based on criminal conduct cannot encompass every scenario and provides generally that disqualification may be based on the commission of any criminal or quasi-criminal act where the act makes the applicant unsuitable for the position of police officer. This language suggests that the Special Order is intended to invest broad discretion in the CPD in disqualifying candidates. For these reasons, we conclude that the Boards interpretation was contrary to both the Special Orders plain language and well-settled principles of statutory construction.
¶ 21 When the Board concluded as a matter of law that one instance of violence constituting a misdemeanor committed more than three years before the candidates submission of his personal history questionnaire is per se insufficient to warrant disqualification, it prohibited CPD from exercising its discretion. Certainly, there are situations where, in CPDs discretion, it could determine that a single misdemeanor act of domestic violence disqualifies a candidate from eligibility for employment. By way of example, if the battery was committed against a candidates pregnant wife with other small children present, CPD could determine that those aggravating circumstances render the candidate ineligible no matter when the conduct occurred.
¶ 22 Having determined that the Board erred in its interpretation of the Special Order, we turn to the proper remedy. We cannot merely remand with directions for the Board to remove OConnors name from the eligibility list, as the CPDs initial decision to disqualify OConnor was based on both the 2003 and 2014 incidents, and the hearing officer determined that it was not more likely than not that the incident in 2014 in fact occurred. Given that OConnors disqualification was based on two incidents of domestic battery, CPD was not given the opportunity to consider whether the circumstances of the first incident warranted disqualification. Therefore, the appropriate course is to allow the CPD to exercise its discretion to determine if the 2003 incident alone disqualifies OConnor. In making this determination, the CPD may consider the fact that, while OConnor disclosed the incident in his personal history questionnaire, his description of slamming the door in his mothers face, which he included in the questionnaire, was at odds with (i) the police report, which indicated that OConnor grabbed his mothers neck and threw her to the floor and told police he didnt grab her that hard, and (ii) his testimony at the hearing.
¶ 23 CONCLUSION
¶ 24 For the foregoing reasons, we affirm the decision of the circuit court and remand to the circuit court with directions to remand to the Board with the further direction to remand to the CPD to determine whether the single incident of conduct constituting domestic violence engaged in by OConnor is grounds for discretionary disqualification.
¶ 25 Affirmed and remanded with directions.
Justices Hoffman and Pucinski concurred in the judgment and opinion.
Justice Hoffman, Justice of the Sixth Division, was designated as the third panel member following recusals by other members of the Second Division.
At the hearing, evidence was also introduced regarding the 2014 incident, but because the hearing officer found that it was not more likely than not that OConnor committed domestic battery in 2014, and because that finding is not challenged on appeal, we find it unnecessary to recount that evidence here.
