"In considering the constitutionality of a legislative enactment, courts must exercise due restraint, in recognition of the principle of the separation of powers in government among the judicial, legislative and executive branches. W.Va. Const. art. V, 1. Every reasonable construction must be resorted to by the courts in order to sustain constitutionality, and any reasonable doubt must be resolved in favor of the constitutionality of the legislative enactment in question. Courts are not concerned with questions relating to legislative policy. The general powers of the legislature, within constitutional limits, are almost plenary. In considering the constitutionality of an act of the legislature, the negation of legislative power must appear beyond reasonable doubt.' State ex rel. Appalachian Power Co. v. Gainer, 149 W. Va. 740, 143 S.E.2d 351 (1965)." West Virginia Public Employees Retirement System v. Dodd, 183 W. Va. 544, 396 S.E.2d 725 (1990). Robinson, 186 W. Va. at 722, 414 S.E.2d at 879. We then identified the level of constitutional scrutiny which is applied to issues affecting economic rights: "Where economic rights are concerned, we look to see whether the classification is a rational one based on social, economic, historic or geographic factors, whether it bears a reasonable relationship to a proper governmental purpose, and whether all persons within the class are treated equally. Where such classification is rational and bears the requisite reasonable relationship, the statute does not violate Section 10 of Article III of the West Virginia Constitution, which is our equal protection clause."
