Day, William R. Summary

  • Last updated on November 11, 2022

The first of President Theodore Roosevelt’s Supreme Court appointees, Day supported antitrust regulation and state power to regulate economic rights. In his most important opinion, he struck down the Keating-Owen Child Labor Act (1916).

Born in Ohio in 1849, Day was descended from a family of judges. His grandfather and father served as justices on state supreme courts. Day followed in their footsteps, graduating from law school and running his own law practice. During his law career, he became friends with the Republican governor, William McKinley. When McKinley was elected president, he appointed Day to the State Department. McKinley’s successor, Theodore Roosevelt, was soon faced with his first Supreme Court appointment and searched for a judge who would favor his antitrust policies. He settled on Day.Keating-Owen Child Labor ActRoosevelt, Theodore;nominations to the CourtKeating-Owen Child Labor Act

The justice did not disappoint him. In the first important antitrust case for the administration, Northern Securities Co. v. United States (1904),[case]Northern Securities Co. v. United States[Northern Securities Co. v. United States] Day provided the critical fifth vote in support of the government’s prosecution of the company. Throughout his career, the justice consistently supported government regulation of monopolies.

Day was also a swing vote on the critical legal issue of the day, economic rights. Although he was willing to uphold some state economic regulations, he consistently voted to strike down federal economic regulations. It was these contradictory beliefs that placed Day on different sides of important cases during his Court tenure. For example, Day dissented in Lochner v. New York (1905),[case]Lochner v. New York[Lochner v. New York] where the Court struck down a state workday maximum-hour law as a violation of liberty of contract. He also disagreed with the Court’s decision in Coppage v. Kansas (1915),[case]Coppage v. Kansas[Coppage v. Kansas] in which a five-member majority struck down a state law prohibiting antiunion employment contracts.

Day did vote to limit federal power in prosecutions. He authored the Court’s opinion in Weeks v. United States (1914).[case]Weeks v. United States[Weeks v. United States] In Weeks, the Court created the federal exclusionary rule, which prohibited the use of any evidence in trial if that evidence had been obtained in violation of the Fourteenth Amendment. The exclusionary rule was used by subsequent Courts to overturn convictions in federal and state cases.

Day is probably best known for his opinion in Hammer v. Dagenhart (1918).[case]Hammer v. Dagenhart[Hammer v. Dagenhart] In Hammer, Day wrote for a narrow majority in striking down the Keating-Owen Child Labor Act of 1916. The act prohibited the shipment across state lines of products made by children under the age of fourteen. Day stated that the regulation intruded upon the state power to regulate labor.

After the Hammer decision, Day served as a justice for four more years, but old age and ill health made him a less productive member of the Court. By 1922 he had become unable to complete his duties and, after consultation with his colleagues, decided to resign.Day, William R.
