In Johnson v. State Hearing Examiner's Office, 838 P.2d 158, 172 (Wyo. 1992), the Court outlined the four elements of the test to be applied in determining whether statutory classifications violate equal protection provisions of the Wyoming Constitution: (1) what class is harmed by the legislation and has the group been subjected to a tradition of disfavor by our laws; (2) what is the public service to be served by the law; (3) what is the characteristic of the disadvantaged class that justifies disparate treatment; (4) how are the characteristics used to distinguish people for disparate treatment relevant to the purpose the challenged law purportedly intends to serve. 838 P.2d at 166-67.
