delivered the opinion of the court:
In December 1995, plaintiff, Connie Harrison, filed a civil action against Hardin County Community Unit School District No. 1 (school district), Joshua Davis and his grandfather, Jimmy Davis, for injuries she sustained in a motor vehicle accident. Claims against Jimmy Davis and Joshua Davis, who was driving his grandfather’s car when he lost control and struck plaintiffs vehicle, were settled. Plaintiff’s complaint alleged that the school district was liable because its personnel were willful and wanton in refusing Joshua Davis’s request to leave school early due to inclement weather and deteriorating road conditions. The school district filed a motion for summary judgment maintaining, inter alia, that it was entitled to immunity under section 2 — 201 of the Local Governmental and Governmental Employees Tort Immunity Act (Act) (745 ILCS 10/2 — 201 (West 1994)). The circuit court of Hardin County granted the school district summary judgment. The appellate court reversed. 313 Ill. App. 3d 702. We granted the school district’s petition for leave to appeal pursuant to Supreme Court Rule 315 (177 Ill. 2d R. 315).
BACKGROUND
On December 8, 1995, Joshua Davis, age 16, drove his grandfather’s car to school. Joshua was a student at Hardin County High School, which is owned and operated by the school district. During the school day, a mixture of freezing rain, sleet, and snow began falling in Hardin County.
At his evidentiary deposition, Joshua Davis testified that during his lunch period, at approximately 11:40 a.m., he approached his principal, Ron Brumley, and asked if he could leave school early because of the deteriorating weather conditions. Joshua told Brumley that he wanted to leave early before it started snowing heavily because he “didn’t want to have a wreck.” Brumley told Joshua that all of the students who drove to school would be dismissed early, at a certain time after lunch. After the lunch period ended, Joshua went to his next class and asked his teacher if he could use the phone to call his parents to get permission to leave early. The teacher told Joshua to sit down and that school would be dismissed early.
Joshua further testified that school was dismissed at approximately 12:15 p.m. that day. Accompanied by three other students, including his girlfriend, Michelle Williams, Joshua drove his grandfather’s car from school. Joshua passed the driveway to his home and continued toward his girlfriend’s house. En route, Joshua lost control of the vehicle, crossed the center line, and struck the front of plaintiffs vehicle. Joshua admitted that if he had wanted to ride the bus, that option would have been available to him. Joshua further acknowledged that the accident would not have occurred had he not been taking his girlfriend home and that there was no reason why he could not have asked his girlfriend to ride home on the bus and driven himself directly home.
Ron Brumley, principal of Hardin County High School, testified that a procedure was in place by which parents could call the school and request that their children be dismissed early. If an individual student asked to leave early due to inclement weather, the school usually required parental permission. The school allowed students to call home to ask their parents if they could leave school early. Brumley stated he may deny a student’s request to call home if school was going to be dismissed within a short period of time.
In plaintiffs complaint, she alleged that the accident and her injuries were “directly and proximately caused” •by the following willful and wanton acts committed by school district personnel:
“a. Refused to allow Joshua Davis to leave school when it was safe to do so given the deteriorating weather conditions on local roads;
b. Permitted Joshua Davis to leave school property in a motor vehicle after having been advised by the student that he had difficulty driving in inclement weather conditions;
c. Failed to call Joshua Davis’ grandparents, parents, and/or adult guardian to have him picked up from school.” The circuit court granted the school district’s motion
for summary judgment based on the immunity protections of section 2 — 201 of the Act. The appellate court, with one justice dissenting, held that Brumley’s decision not to allow Joshua to leave early was not an exercise of discretion in the determination of policy and, thus, did not fall within the protections of the Act. 313 Ill. App. 3d at 707. The appellate court reversed the judgment of the circuit court granting summary judgment in favor of the school district. 313 Ill. App. 3d at 708. We granted the school district’s petition for leave to appeal pursuant to Supreme Court Rule 315 (177 Ill. 2d R. 315).
ANALYSIS
Summary judgment is proper “where the pleadings, affidavits, depositions, admissions, and exhibits on file, when viewed in the light most favorable to the nonmovant, reveal that there is no genuine issue as to any material fact and that the movant is entitled to judgment as a matter of law.” Busch v. Graphic Color Corp., 169 Ill. 2d 325, 333 (1996); 735 ILCS 5/2 — 1005(c) (West 1996). If the party moving for summary judgment supplies facts that, if not contradicted, would warrant judgment in its favor as a matter of law, the opponent cannot rest on his pleadings to create a genuine issue of material fact. Purtill v. Hess, 111 Ill. 2d 229, 240-41 (1986); Carruthers v. B.C. Christopher & Co., 57 Ill. 2d 376, 380 (1974); see also Fitzpatrick v. Human Rights Comm’n, 267 Ill. App. 3d 386, 391 (1994). Our review of an order granting summary judgment is de novo. Zekman v. Direct American Marketers, Inc., 182 Ill. 2d 359, 374 (1998).
In 1959, this court abolished the doctrine of sovereign immunity. See Molitor v. Kaneland Community Unit District No. 302, 18 Ill. 2d 11 (1959). In response to Molitor, the General Assembly, in 1965, enacted the Local Governmental and Governmental Employees Tort Immunity Act (Act) (745 ILCS 10/1 — 101 et seq. (West 1998)). Under the Act, Illinois adopted the principle that local governmental units are liable in tort, but limited this liability with an extensive list of immunities based on specific government functions. Burdinie v. Village of Glendale Heights, 139 Ill. 2d 501, 506 (1990). The 1970 Illinois Constitution also abolished the doctrine of sovereign immunity, except as the General Assembly may provide by law. Ill. Const. 1970, art. XIII, § 4. Accordingly, the Act governs whether and in what situations local governmental units are immune from civil liability. See Epstein v. Chicago Board of Education, 178 Ill. 2d 370, 375 (1997).
In this case, the school district claims that it is absolutely immune from liability under the Act. Section 2 — 201 states:
“Except as otherwise provided by Statute, a public employee serving in a position involving the determination of policy or the exercise of discretion is not liable for an injury resulting from his act or omission in determining policy when acting in the exercise of such discretion even though abused.” 745 ILCS 10/2 — 201 (West 1994).
Also relevant here is section 2 — 109 of the Act, which immunizes a local public entity from liability for an injury resulting from an employee’s act or omission where the employee is not liable. 745 ILCS 10/2 — 109 (West 1994). In construing the Act, our primary goal is to ascertain and give effect to the intent of the legislature. Harinek v. 161 North Clark Street Ltd. Partnership, 181 Ill. 2d 335, 340 (1998). Further, we will not depart from the plain language of the Act by reading into it exceptions, limitations, or conditions that conflict with the express legislative intent. In re Chicago Flood Litigation, 176 Ill. 2d 179, 193 (1997). These grants of immunity to public officials are premised upon the idea that such officials should be allowed to exercise their judgment in rendering decisions without fear that a good-faith mistake might subject them to liability. See White v. Village of Homewood, 285 Ill. App. 3d 496, 502 (1996).
This court has determined that section 2 — 201 requires the act or omission to be both a determination of policy and an exercise of discretion. Harinek, 181 Ill. 2d at 341. Cases considering this Act have recognized a distinction between “discretionary duties, the negligent performance of which does not subject a municipality to tort liability, and ministerial duties, the negligent performance of which can subject a municipality to tort liability.” Snyder v. Curran Township, 167 Ill. 2d 466, 473 (1995). This court has held that “discretionary acts are those which are unique to a particular public office, while ministerial acts are those which a person performs on a given state of facts in a prescribed manner, in obedience to the mandate of legal authority, and without reference to the official’s discretion as to the propriety of the act.” Snyder, 167 Ill. 2d at 474. Further, this court has defined policy decisions as those that require the governmental entity or employee to balance competing interests and to make a judgment call as to what solutions will best serve each of those interests. West v. Kirkham, 147 Ill. 2d 1, 11 (1992). Both parties agree that principal Brumley’s actions were discretionary in nature. However, they disagree as to whether Brumley was determining policy when he denied Joshua’s request to be dismissed early.
In Harinek, an office worker was struck by a door during a fire drill after being instructed by the City of Chicago’s fire marshall to stand near the door. This court, applying the Kirkham definition of policy decisions, found that section 2 — 201 immunized the City from liability because the fire marshall’s decision involved a determination of policy and an exercise of discretion. Harinek, 181 Ill. 2d at 343. We stated that in planning and conducting fire drills, the fire marshall had to balance various interests that might compete for the time and resources of the fire department, including the interests of efficiency and safety. Harinek, 181 Ill. 2d at 342. The marshall’s decision regarding the placement of fire drill participants served to balance these interests, and the marshall’s “acts and omissions were undertaken in determining policy within the meaning of the statute.” Harinek, 181 Ill. 2d at 343.
The appellate court applied the Harinek principles in Johnson v. Decatur Park District, 301 Ill. App. 3d 798 (1998). In that case, a youth was injured in a fall at a power tumbling practice and alleged that the park district, which had hired his coach, acted willfully and wantonly in failing to warn of the dangers associated with using a mini-trampoline and mats and to provide certain safety measures and equipment. The plaintiffs also alleged negligence and willful and wanton conduct ón the part of the coach. Johnson, 301 Ill. App. 3d at 801. The appellate court affirmed the circuit court’s grant of summary judgment in favor of the park district and its coach pursuant to the Act. Johnson, 301 Ill. App. 3d at 810. As to the coach, the court found that he determined what maneuvers the tumblers would perform, whether each tumbler was capable of performing those maneuvers, and what equipment and safety precautions were needed. Johnson, 301 Ill. App. 3d at 809. Thus, the coach had to consider each tumbler’s abilities, balance these interests against the resources of the park district, and make a judgment as to how best to perform his coaching duties. The court found that this qualified as the making of policy under Harinek, and thus the coach’s actions were immunized under section 2—201 of the Act. Johnson, 301 Ill. App. 3d at 809-10.
In this case, Brumley had to consider the circumstances surrounding Joshua’s request, including the weather and road conditions, Joshua’s safety, and the lack of permission from Joshua’s parents or guardian. Brumley then had to balance the competing interests of Joshua’s desire to leave early before the weather worsened with that of the school’s interest in an orderly dismissal, along with the possibility that if one student was dismissed early then, in the future, every student would want to leave early. Brumley then had to make a judgment as to how best to perform his duties as principal and find a solution that best served all of these interests. Just as the actions of the fire marshall in Harinek and the coach in Johnson constituted policy determinations, Brumley also made a policy decision when he refused Joshua’s request for early dismissal and instead told him to wait for the entire school to be dismissed early.
Plaintiff argues that Brumley could not have been determining policy because his decision only impacted an individual student. In that regard, the appellate court stated that Brumley’s decision was not an exercise of discretion in the determination of policy because it was not a decision at the “planning level” and “did not involve the formulation of principles to achieve a common public benefit.” 313 Ill. App. 3d at 707. We disagree. The language of section 2 — 201 and the cases considering its applicability do not require that the decision achieve a common public benefit to come within the Act’s immunity protections. Under the principles set forth in Harinek, Brumley’s actions clearly qualify as the making of policy. Based on this analysis, we hold that the school district enjoys the immunity protections provided under section 2 — 201.
CONCLUSION
For the foregoing reasons, the judgment of the appellate court is reversed, and the judgment of the circuit court of Hardin County is affirmed.
Appellate court judgment reversed; circuit court judgment affirmed.
