Curtis v.

Commonwealth v. Albertgreen2 sentences2020In Commonwealth v. Albert, 563 Pa 133, 758 A.2d 1149 (2000), we noted that the essence of the equal protection doctrine is that "'like persons in like circumstances will be treated similarly [X" but recognized that the right to equal protection "'does not absolutely prohibit the Commonwealth from classifying individuals for the purposes of receiving equal treatment [.]'" Id. at 1151 {citations omitted). 2020In Commonwealth v.

Love v. Borough of Stroudsburggreen2 sentences2023Thus, to evaluate an equal protection claim, a court must first determine “the type of interest at issue.” Love, 597 A.2d at 1139 . “[T]here are three different types of classifications calling for three different standards of judicial review.” James v. Se. 2017Should the statutory classification in question fall into the first category, the statute is strictly construed in light of a “compelling” governmental purpose; if the classification falls into the second category, a heightened standard of scrutiny is applied to an “important” governmental purpose; and if the statutory scheme falls into the third category, the statute is upheld if there is any rational basis for the classification. 8 Although Petitioner does not make it clear whether he is pursuing an equal protection claim under the United States Constitution or the Pennsylvania Constitution, | 3 | 6 |
