In Probst v. Department of Transportation, Bureau of Driver Licensing, 578 Pa. 42, 849 A.2d 1135, 1144 (2004), our Supreme Court stated: In applying the rational basis test, we have adopted a two-step analysis. First, we determine whether the challenged statute seeks to promote any legitimate interest or public value. If so, we then determine whether the classification adopted in the legislation is reasonably related to accomplishing that articulated state interest or interests. In undertaking this analysis, we are free to hypothesize reasons the legislature might have had for the classification, and will not declare a genuine classification void even if we might question the soundness or wisdom of the distinction. Furthermore, we keep in mind that because presumption of constitutionality attaches to any lawfully enacted legislation, the burden is upon the party attacking a statute to rebut the presumption of constitutionality by a clear, palpable, and plain demonstration that the rational basis test is not met. 849 A.2d at 1144.
