CHIEF JUSTICE FREEMAN
delivered the judgment of the court:
Sections 24 — 24 and 34 — 84a of the School Code (105 ILCS 5/24 — 24, 34 — 84a (West 1994)) immunize teachers and certain other educational employees from liability for injuries caused by their negligent supervision of school activities. To recover for such an injury, a plaintiff student must plead and prove that the teacher committed willful and wanton misconduct by such supervision. Kobylanski v. Chicago Board of Education, 63 Ill. 2d 165, 171-73 (1976). Those sections apply equally to public and private schools. See, e.g., Hilgendorf v. First Baptist Church, 157 Ill. App. 3d 428, 429 (1987).
Also, when properly raised, the Local Governmental and Governmental Employees Tort Immunity Act (Tort Immunity Act or Act) provides an extensive list of immunities to local governmental units, specifically including school districts. 745 ILCS 10/2 — 106 (West 1994). Section 3 — 108(a) of the Act immunizes a local public entity or a public employee from liability for an injury caused by a failure to supervise an activity on, or a failure to supervise the use of, any public property. 745 ILCS 10/3 — 108(a) (West 1994). Section 3 — 108(a) immunizes local public entities and employees from liability based on both ordinary negligence and willful and wanton misconduct. Barnett v. Zion Park District, 171 Ill. 2d 378, 391-92 (1996). The Tort Immunity Act does not apply to private schools. Cooney v. Society of Mt. Carmel, 75 Ill. 2d 430, 434 (1979).
The question presented for review is which statute’s immunity controls in a case involving the failure to supervise public school activities: the immunity provided by the School Code, or the immunity provided by the Tort Immunity Act when properly raised? We hold that in such a case the immunity provided by the Tort Immunity Act controls.
BACKGROUND
This cause is before us following a motion to dismiss pursuant to section 2 — 619(a)(9) of the Code of Civil Procedure (735 ILCS 5/2 — 619(a)(9) (West 1994)). The motion admits all well-pled allegations in the complaint and reasonable inferences to be drawn from the facts. Fireman’s Fund Insurance Co. v. SEC Donahue, Inc., 176 Ill. 2d 160, 161 (1997).
The complaint alleges as follows. On February 14, 1994, plaintiff, Joshua A. Henrich, underwent spine fusion surgery for a lower back medical condition. On September 2, 1994, plaintiffs surgeon advised plaintiff in a letter that he was permanently restricted from participating in “contact sports, such as wrestling and football in gym class at school.” On or before January 25, 1995, defendant Libertyville High School District 128 (district) had received a copy of the letter and also had actual knowledge of plaintiffs lower back condition and the permanent restrictions on his activities in physical education class.
On February 2, 1995, plaintiff was a 17-year-old student at Libertyville High School. On that date, a substitute physical education instructor supervised the physical education class at the high school’s pool area. The instructor required plaintiff to participate in a game of water basketball. The district knew or should have known that water basketball involved physical contact between the players. While participating in the water basketball game, plaintiff was severely and permanently injured.
Plaintiff brought a personal injury action in the circuit court of Lake County against the district, the high school (collectively, the district), and Justin Burg, a fellow student. Count I of the three-count complaint alleged that the district required, allowed, or failed to prohibit plaintiff’s participation in the water basketball game. The district so acted knowing that the game involved physical contact, knowing of plaintiffs medical condition, and knowing of the permanent medical restrictions on his activities due to his medical condition. Count I also alleged that the district allowed Burg to participate in the game knowing that Burg was a particularly rough player. Count I alleged that the district’s acts constituted willful and wanton misconduct.
Count II reiterated the above acts and additionally alleged that the district assigned a noncertified or inadequately trained substitute teacher to the physical education class, and failed to adequately supervise the class. Count II alleges that those acts constituted ordinary negligence.
Count III is directed against Burg and alleges negligence. Burg subsequently brought a counterclaim against the district seeking contribution.
The district filed a combined motion to dismiss the complaint. See 735 ILCS 5/2 — 619.1 (West 1994). The district sought the dismissal of count I on the ground that it failed to state a cause of action for willful and wanton misconduct. See 735 ILCS 5/2 — 615 (West 1994). The trial court denied this part of the motion.
The district also sought the dismissal of counts I and II on the ground that the district was immune from liability under the Tort Immunity Act (745 ILCS 10/1— 101 et seq. (West 1994)). See 735 ILCS 5/2 — 619(a)(9) (West 1994). The district argued that section 3 — 108(a) of the Act immunized it from counts I and II. The district also argued that section 3 — 109 of the Act additionally immunized it from the claims contained in count II. 745 ILCS 10/3 — 108(a), 3 — 109 (West 1994).
In separate orders, the circuit court dismissed counts I and II based on the Tort Immunity Act. In dismissing count I, the court expressly found that section 3 — 108(a) immunized the district from count I. The court also dismissed Burg’s counterclaim for contribution against the district. The court noted that count III, directed against Burg, remained pending. The court also found that its orders were final and appealable. See 155 Ill. 2d R. 304.
On appeal, plaintiff contested only the dismissal of count I, which alleged willful and wanton misconduct. The appellate court upheld the dismissal. 289 Ill. App. 3d 809. The court addressed the issue of which statutory immunity controlled the disposition of count I: section 24 — 24 of the School Code (105 ILCS 5/24 — 24 (West 1994)), or section 3 — 108(a) of the Tort Immunity Act (745 ILCS 10/3 — 108(a) (West 1994)). The appellate court concluded that the immunity provided by section 3 — 108(a) of the Act was available to the district. Since that section immunizes willful and wanton misconduct, the appellate court upheld the dismissal of count I. 289 Ill. App. 3d at 817.
We allowed plaintiffs petition for leave to appeal (166 Ill. 2d R. 315). We subsequently granted the Illinois Trial Lawyers Association leave to file an amicus curiae brief in support of plaintiff; we also granted the Chicago Board of Education, the Illinois Association of School Boards, and the Illinois Association of School Administrators leave to file an amicus curiae brief in support of the district. 155 Ill. 2d R. 345. We now affirm the judgment of the appellate court.
DISCUSSION
Section 2 — 619(a)(9) of the Code of Civil Procedure permits dismissal where “the claim asserted *** is barred by other affirmative matter avoiding the legal effect of or defeating the claim.” 735 ILCS 5/2 — 619(a)(9) (West 1994). When ruling on a motion to dismiss, the trial court must interpret all pleadings and supporting documents in the light most favorable to the nonmoving party. The court should grant the motion only if the plaintiff can prove no set of facts that would support a cause of action. On appeal, review is de novo. In re Chicago Flood Litigation, 176 Ill. 2d 179, 189 (1997).
This controversy centers upon the interpretation of two immunity statutes. Plaintiff contends that section 24 — 24 of the School Code (105 ILCS 5/24 — 24 (West 1994)) controls the disposition of count I. According to plaintiff, since that section does not immunize willful and wanton misconduct, then count I stands. On the other hand, the district contends that section 3 — 108(a) of the Tort Immunity Act (745 ILCS 10/3 — 108(a) (West 1994)) controls the disposition of count I. According to the district, since that section immunizes willful and wanton misconduct, then count I was properly dismissed.
To resolve this issue, we must interpret these two statutes. The primary rule of interpreting statutes, to which all other rules are subordinate, is that a court should ascertain and give effect to the intent of the legislature. The court should seek the legislative intent primarily in the language of the statute. Also, the statute should be evaluated as a whole; the language within each section of a statute must be examined in light of the entire statute. Abrahamson v. Illinois Department of Professional Regulation, 153 Ill. 2d 76, 91 (1992). When this court has interpreted a statute, that interpretation is considered as part of the statute itself unless and until the legislature amends it contrary to the interpretation. Miller v. Lockett, 98 Ill. 2d 478, 483 (1983); see People v. Woodard, 175 Ill. 2d 435, 443-44 (1997).
Section 3 — 108(a) of the Tort Immunity Act provides in pertinent part that:
“neither a local public entity nor a public employee is liable for an injury caused by a failure to supervise an activity on or the use of any public property.” 745 ILCS 10/3—108(a) (West 1994).
Further, a “ ‘[ljocal public entity’ includes a *** school district.” 745 ILCS 10/1 — 206 (West 1994). Also, the Act must be raised and pled as an affirmative defense or else it is waived, even if the evidence supports the existence or appropriateness of the defense. Martin v. Chicago Housing Authority, 264 Ill. App. 3d 1063, 1075 (1994); First National Bank v. Village of Mundelein, 166 Ill. App. 3d 83, 90 (1988).
The plain language of section 3 — 108(a) does not contain an exception for willful and wanton misconduct. Based on this plain language, this court has interpreted section 3 — 108(a) to immunize willful and wanton misconduct. Barnett, 171 Ill. 2d at 391-92. We note that the School Code was not at issue in Barnett.
In this case, the district raised the affirmative defense of the Tort Immunity Act. The district contends that since it is a local public entity, then section 3 — 108(a) applies to count I.
At the time this cause arose, section 24 — 24 of the School Code, which applies to cities with a population of less than 500,000, and section 34 — 84a of the Code, which applies to cities with a population of greater than 500,000, provided in pertinent part that:
“[bleachers and other certificated educational employees shall maintain discipline in the schools, including school grounds which are owned or leased by the board and used for school purposes and activities. In all matters relating to the discipline in and conduct of the schools and the school children, they stand in the relation of parents and guardians to the pupils. This relationship shall extend to all activities connected with the school program, including all athletic and extracurricular programs, and may be exercised at any time for the safety and supervision of the pupils in the absence of their parents or guardians.” 105 ILCS 5/24 — 24, 34 — 84a (West 1994).
By its plain language, section 24 — 24 confers on educators the status of parent or guardian to their pupils. Therefore, this statute grants educators the immunity that parents enjoy (Kobylanski, 63 Ill. 2d at 170-73), and which school districts vicariously enjoy (Sidwell v. Griggsville Community Unit School District No. 4, 146 Ill. 2d 467, 472-73 (1992)).
Section 24 — 24 of the School Code confers on teachers in loco parentis status in all matters relating to the supervision of students in school activities. This court has interpreted section 24 — 24 to immunize ordinary negligence, but not to immunize willful and wanton misconduct. Gerrity v. Beatty, 71 Ill. 2d 47, 50 (1978); Kobylanski, 63 Ill. 2d at 171-73. This interpretation is keyed to the rule that parents are not liable to their children for ordinary negligence, but are liable for willful and wanton misconduct. Thomas v. Chicago Board of Education, 77 Ill. 2d 165, 171 (1979); Kobylanski, 63 Ill. 2d at 170.
We note that this court has narrowed parental immunity to cover only ordinary negligence arising from conduct that is inherent to the parent-child relationship, i.e., conduct that concerns parental discretion in discipline, supervision, and care of the child. Absent such conduct, a child may recover from a parent for negligence. Cates v. Cates, 156 Ill. 2d 76, 104-05 (1993). As a result of Cates, the educator immunity provided by section 24 — 24 of the School Code is accordingly narrowed. See Cates, 156 Ill. 2d at 110-11 (Miller, C.J., dissenting); Stiff v. Eastern Illinois Area of Special Education, 279 Ill. App. 3d 1076, 1080-81 (1996).
Plaintiff contends that since this cause arose from the supervision of students in a school physical education program, then section 24 — 24 applies to count I.
This court has noted that the immunity provided by section 24 — 24 of the School Code did not derive from the immunity provided by the Tort Immunity Act. Kobylanski, 63 Ill. 2d at 174. This has indicated to the appellate court that section 24 — 24 of the School Code and section 3 — 108(a) of the Tort Immunity Act are to be interpreted as two independent statutes. Lewis v. Jasper County Community Unit School District No. 1, 258 Ill. App. 3d 419, 421 (1994); Bowers v. Du Page County Regional Board of School Trustees District No. 4, 183 Ill. App. 3d 367, 377 (1989). We agree and so hold.
It appears from this examination of section 3 — 108(a) of the Tort Immunity Act and section 24 — 24 of the School Code that both immunities apply to count I. Not only must we accept as true the allegations of willful and wanton misconduct contained in count I, but also the circuit court found that count I stated a cause of action. Accordingly, under section 3 — 108(a) of the Tort Immunity Act, count I cannot stand. However, under section 24 — 24 of the School Code, count I stands. Thus, the two statutes appear to conflict in this case.
Plaintiff argues that section 24 — 24 of the School Code controls the disposition of count I because it is more specific than section 3 — 108(a) of the Tort Immunity Act. It is a well-settled rule of statutory construction that “ ‘[wjhere there are two statutory provisions, one of which is general and designed to apply to cases generally, and the other is particular and relates to only one subject, the particular provision must prevail.’ ” Hernon v. E.W. Corrigan Construction Co., 149 Ill. 2d 190, 195 (1992), quoting Bowes v. City of Chicago, 3 Ill. 2d 175, 205 (1954). A policy expressed in the specific statutory provision should prevail over general statutory statements. Sierra Club v. Kenney, 88 Ill. 2d 110, 126 (1981).
The appellate court in this case acknowledged that both section 24 — 24 of the School Code and section 3 — 108(a) of the Tort Immunity Act applied to count I. 289 Ill. App. 3d at 814-15. The court concluded that section 3 — 108(a) controlled the disposition of count I. The appellate court described the immunity that section 24 — 24 of the School Code provides as not arising directly from the statute. Rather, according to the appellate court, “whatever immunity section 24 — 24 provides arises indirectly from the in loco parentis relationship of teachers and other educational employees with students.” Further, the court noted that “any immunity provided to a school district by section 24 — 24 is vicarious in that it is derived from the immunity provided to teachers and other educational employees.” In contrast, the appellate court described the immunity provided by section 3 — 108(a) of the Tort Immunity Act, read with section 1 — 206 of the Act, as “much more direct and specific than section 24 — 24 of the School Code.” 289 Ill. App. 3d at 815.
We need not decide whether section 3 — 108(a) of the Tort Immunity Act is more specific than section 24 — 24 of the School Code. Rather, we can ascertain the legislative intent from the plain language of section 3 — 108(a) and can give it effect without resorting to other aids for construction. See Illinois Power Co. v. Mahin, 72 Ill. 2d 189, 194 (1978), quoting Western National Bank v. Village of Kildeer, 19 Ill. 2d 342, 350 (1960). Where the language of a statute is unambiguous, the only legitimate function of the courts is to enforce the law as enacted by the legislature. Certain Taxpayers v. Sheahen, 45 Ill. 2d 75, 84 (1970). There is no rule of construction which authorizes a court to declare that the legislature did not mean what the plain language of the statute says. Illinois Power Co., 72 Ill. 2d at 194, quoting Western National Bank, 19 Ill. 2d at 350.
In the present case, the plain language of section 3 — 108(a) of the Tort Immunity Act immunizes a local public entity’s failure to supervise an activity on or the use of public property (745 ILCS 10/3 — 108(a) (West 1994)), and a “local public entity” expressly includes a school district (745 ILCS 10/1 — 206 (West 1994)). The legislature could not have made its intent any plainer.
We reach our conclusion that section 3 — 108(a) of the Tort Immunity Act controls the disposition of count I also by comparing the plain language of that section with section 24 — 24 of the School Code. A court presumes that two or more statutes which relate to one subject are governed by one spirit and policy, and that the legislature intended the statutes to be operative and harmonious. Therefore, statutes relating to the same subject must be compared and so construed with reference to each other that effect may be given to all of the provisions of each, if it can fairly and reasonably be done. Ashton v. County of Cook, 384 Ill. 287, 298 (1943).
We note that the Seventy-fourth General Assembly enacted section 24 — 24 of the School Code (1965 Ill. Laws 1459 (passed June 28, 1965)) and the Tort Immunity Act (1965 Ill. Laws 2982 (passed June 30, 1965)) only two days apart. Statutes that relate to the same subject matter, passed at the same session of the General Assembly, should be interpreted with reference to each other. A court should not consider such statutes inconsistent if it is possible to interpret them otherwise. People ex rel. Vaughan v. Thompson, 377 Ill. 244, 249 (1941).
In the present case, section 3 — 108(a) of the Tort Immunity Act and section 24 — 24 of the School Code each stands in its own sphere. Section 24 — 24 of the School Code applies equally to public and private schools. See Hilgendorf, 157 Ill. App. 3d at 429; Cotton v. Catholic Bishop, 39 Ill. App. 3d 1062 (1976); Merrill v. Catholic Bishop, 8 Ill. App. 3d 910 (1972). In contrast, the Tort Immunity Act does not apply to private schools, but only to public schools. Cooney, 75 Ill. 2d at 434. Although “public and private schools may sometimes be classified together in light of the similarity of their functions and activities *** it does not follow that the legislature is required to adopt that classification in the *** Tort Immunity Act.” Cooney, 75 Ill. 2d at 435. By the plain language of section 3 — 108(a) of the Tort Immunity Act, the legislature has chosen to grant public school teachers and public school districts greater immunity than private school teachers and private schools.
By giving effect to the plain language of section 3 — 108(a) of the Tort Immunity Act, we effectuate the purposes of both section 3 — 108(a) and section 24 — 24 of the School Code. The Act itself states that its purpose is “to protect local public entities and public employees from liability arising from the operation of government.” 745 ILCS 10/1 — 101.1 (West 1994); accord Bubb v. Springfield School District 186, 167 Ill. 2d 372, 378 (1995) (“By providing immunity, the legislature sought to prevent the diversion of public funds from their intended purpose to the payment of damage claims”).
Sections 24 — 24 and 34 — 84a of the School Code reflect the basic policy “that teachers, standing in loco parentis, should not be subjected to any greater liability than parents, who are liable to their children for willful and wanton misconduct.” Kobylanski, 63 Ill. 2d at 173. This court has explained that those sections:
“reflect a legislative determination that the orderly conduct of the schools and the maintenance of a sound learning atmosphere require that there be a personal relationship between teacher and student in which the teacher has disciplinary and supervisory authority similar to that which exists between parent and child. It is evident that this relationship would be seriously jeopardized if teachers and school districts were amenable to ordinary negligence actions for accidents occurring in the course of the exercise of such authority.” Gerrity, 71 Ill. 2d at 51.
Thus, “[i]n the interest of student-teacher harmony, litigation between them should not be encouraged — absent wilful and wanton conduct.” Thomas, 77 Ill. 2d at 171; accord Albers v. Community Consolidated No. 204 School, 155 Ill. App. 3d 1083, 1085 (1987); see, e.g., Stiff, 279 Ill. App. 3d at 1080-81.
Our interpretation of section 3 — 108(a) of the Tort Immunity Act is consistent with the purpose of either statute. True, the immunities that section 3 — 108(a) of the Tort Immunity Act and section 24 — 24 of the School Code provide serve different purposes. However, both statutes discourage tort claims and, by the plain language of section 3 — 108(a), the legislature has chosen to discourage such claims against public school teachers and school districts more broadly. We conclude that section 3 — 108(a) of the Tort Immunity Act controls the disposition of count I.
According to plaintiff, holding that section 3 — 108(a) of the Tort Immunity Act controls the disposition of count I is absurd and unjust. To him, we are effectively holding that while parents are required to send their children to school, public school teachers have no tort duty of care for their pupils and parents have no recourse for any injuries to their children, even injuries caused by willful and wanton misconduct. A court presumes that the General Assembly, in enacting legislation, did not intend absurdity or injustice. Hernon, 149 Ill. 2d at 195; Halberstadt v. Harris Trust & Savings Bank, 55 Ill. 2d 121, 128 (1973).
However, to hold that section 24 — 24 of the School Code controlled the disposition of count I would effectively delete the explicit language in section 1 — 206 of the Tort Immunity Act that applies section 3 — 108(a) to school districts. In interpreting a statute, a court should, if possible, give significance and effect to every word without destroying the sense or effect of the law. The court should interpret the statute, if possible, so that no word is rendered meaningless or superfluous. People ex rel. Barrett v. Barrett, 31 Ill. 2d 360, 364-65 (1964).
CONCLUSION
It is the province of the legislature to enact laws; it is the province of the courts to construe them. Courts have no legislative powers; courts may not enact or amend statutes. A court cannot restrict or enlarge the meaning of an unambiguous statute. The responsibility for the justice or wisdom of legislation rests upon the legislature. People ex rel. Roan v. Wilson, 405 Ill. 122, 128 (1950); People ex rel. Nelson Brothers Storage & Furniture Co. v. Fisher, 373 Ill. 228, 234 (1940). A court must interpret and apply statutes in the manner in which they are written. A court must not rewrite statutes to make them consistent with the court’s idea of orderliness and public policy. Kozak v. Retirement Board of the Firemen’s Annuity & Benefit Fund, 95 Ill. 2d 211, 220 (1983).
We hold that section 3 — 108(a) of the Tort Immunity Act controls the disposition of count I. Since count I states a cause of action for willful and wanton misconduct, and since section 3 — 108 immunizes willful and wanton misconduct, then count I cannot stand.
For the foregoing reasons, the judgment of the appellate court is affirmed.
Affirmed.
