1999In Adams, the supreme court explained equal protection analysis as follows: “A claim that a statute violates the principles of equal protection requires an analysis of whether a substantial right is involved, or whether the statute discriminates against a suspect class. [Citation.] When neither of these factors comes into play, the equal protection standard, like due process, utilizes a rational basis test, which prevents the implementation of a statute if it irrationally differentiates between persons similarly situated.” Adams, 144 Ill. 2d at 391 .
