2022Thus, for Mr. Spiegel to prevail on his equal protection claim, he would have to show that the Village “intentionally treated [him] differently from others similarly situated and that there is no rational basis for the difference in treatment.” (Emphasis added.) Village of Willowbrook v. Olech, 528 U.S. 562, 564 (2000). ¶ 57 Applying that deferential test here, we reject Mr. Spiegel’s equal protection claim for the same reasons the circuit court did: he has failed to provide any evidence that he was treated differently than other property owners.

1990Even under the deferential rational basis test applied by this court, statistics heretofore cited demonstrate that the arbitrary four-year period of repose does not have a “fair and substantial relation to the object of the legislation.” (Emphasis added.) (Jenkins, 102 Ill. 2d at 477 .) It is, therefore, violative of equal protection guarantees and constitutes special legislation.
