Whether Oregon’s ten-hour limit for women working in laundries unconstitutionally deprived women and their employers of liberty of contract without due process of law.
Holding
No. The hour limitation was a valid exercise of Oregon’s police power and did not violate the Fourteenth Amendment.
Reasoning
The Court recognized that liberty protected by the Fourteenth Amendment includes a general right to make employment contracts. But that liberty is not absolute. States may restrict contracting when a regulation reasonably serves interests within the police power, including health and welfare.
Muller relied heavily on Lochner v. New York, which had invalidated a maximum-hours law for male bakery workers. The Court declined to treat Lochner as controlling because, in its view, the health implications of long hours of labor differed for women and men.
The Court relied on legislative experience, foreign and domestic labor laws, and the extensive factual materials assembled in Louis Brandeis’s brief. Those materials supported what the Court characterized as a widespread and long-standing belief that extended work, particularly prolonged standing, could be harmful to women’s health.
The Court reasoned that women’s physical characteristics and maternal functions could place them at a disadvantage in the struggle for subsistence. It further treated women’s health as a public concern because it believed healthy mothers were important to the welfare of future generations. On that basis, the Court held that Oregon could limit women’s work hours in laundries.
