Whether Michigan violated equal protection by barring women generally from bartending while permitting the wives and daughters of male liquor-establishment owners to be licensed as barmaids.
Holding
No. The classification had a conceivable rational basis and therefore did not deny equal protection.
Reasoning
The Court began from the premise that Michigan could constitutionally prohibit all women from bartending. Regulation of liquor traffic lay within a traditionally broad area of state legislative authority, and the Fourteenth Amendment did not forbid the State from drawing a sex-based line in that setting.
Having permissibly barred women generally, Michigan was not required to extend the prohibition to every woman without exception. Equal protection bars irrational discrimination, but it does not require the law to treat factually different situations as identical or to pursue a regulatory objective with complete symmetry.
Michigan could reasonably believe that the husband’s or father’s ownership and oversight of a bar reduced the moral and social hazards the legislature associated with women tending bar. The Court would not second-guess that legislative judgment so long as the line drawn was not wholly without reason.
The Court also declined to probe legislators’ actual motives. Because the ownership-and-family distinction was rationally entertainable, the Court would not invalidate the statute based on the suggestion that male bartenders sought to monopolize the occupation.
