William R. Day

William R. Day was an American jurist and statesman who served as an Associate Justice of the Supreme Court of the United States from 1903 to 1922. Appointed by President Theodore Roosevelt, he was known for his moderate jurisprudence and pivotal role in shaping early 20th-century constitutional law. Prior to the Supreme Court, he served as United States Secretary of State under President William McKinley during the pivotal period of the Spanish–American War. His legal career was rooted in Ohio, where he was a close political ally of McKinley and served on the United States Court of Appeals for the Sixth Circuit.

Early life and education

Born in Ravenna, Ohio, he was the son of a local judge and attended public schools. He entered the University of Michigan at age sixteen, graduating with a Bachelor of Arts degree in 1870. After graduation, he read law in the office of a prominent Canton attorney and was admitted to the Ohio bar in 1872. He soon established a successful private practice in Canton, where he became deeply involved in local Republican politics and formed a lifelong friendship with fellow attorney William McKinley.

Legal and political career

His legal practice flourished, and his political alliance with William McKinley propelled him into national service. When McKinley became President, he was appointed First Assistant Secretary of State under John Sherman in 1897. He played a crucial administrative role in the State Department during the buildup to the Spanish–American War. In April 1898, he succeeded Sherman as United States Secretary of State, overseeing the diplomatic negotiations that concluded the war, including the Treaty of Paris (1898). He resigned after a brief tenure and was subsequently appointed by McKinley to the newly created United States Court of Appeals for the Sixth Circuit in 1899, where he served until his elevation to the Supreme Court.

Supreme Court service

Nominated by President Theodore Roosevelt in February 1903, his confirmation by the United States Senate was swift, and he took his judicial oath on March 2, 1903. He served on the Court during a period of significant transformation, alongside notable justices like Oliver Wendell Holmes Jr., John Marshall Harlan, and later Louis Brandeis. He was generally considered a centrist, often balancing the conservative views of justices like Rufus W. Peckham with the more progressive leanings of Holmes and Brandeis. He retired from the bench on November 13, 1922, after nearly two decades of service.

Major opinions and jurisprudence

He authored several influential opinions that reflected a pragmatic approach to federal power and economic regulation. In *Hammer v. Dagenhart* (1918), he wrote for the Court, striking down the Keating–Owen Child Labor Act as an overreach of congressional power under the Commerce Clause, a decision later repudiated. Conversely, in *Weeks v. United States* (1914), he authored the landmark opinion establishing the federal exclusionary rule, which barred evidence obtained through illegal searches from being used in federal courts. He also wrote the majority opinion in *United States v. Midwest Oil Co.* (1915), upholding presidential withdrawal of public lands. In important antitrust cases, such as *Standard Oil Co. of New Jersey v. United States* (1911), he concurred with the Court's application of the rule of reason.

Later life and death

Following his retirement from the Supreme Court, he returned to private life but remained active. He accepted an appointment from President Warren G. Harding to serve on the Mixed Claims Commission, an international tribunal established to settle claims between the United States and Germany arising from World War I. His health declined in his final years. He died on July 9, 1923, at his summer home on Mackinac Island, Michigan, and was interred in the West Lawn Cemetery in Canton, Ohio. His papers are held at the Library of Congress and the University of Michigan.
