In Fumarolo v. Chicago Board of Education (1990), 142 Ill. 2d 54, 105, 566 N.E.2d 1283, 153 Ill. Dec. 177, the Court found that "there is no indication in the statute or in our State law that the legislature intended to create vested contractual rights through enactment of the statute." The Court further held that: "The legislature must be free to exercise its constitutional authority without concern that each time a public policy is expressed contractual rights may thereby be created." Id. at 106.
