Justice Harlan Fiske Stone served on the United States Supreme Court for twenty-one years, joining as an Associate Justice in 1925 and sitting as the twelfth Chief Justice from 1941 until his death in 1946. He is the only Justice ever to have occupied every seat on the bench. A lifelong Republican elevated to the center chair by Franklin Roosevelt, Stone reshaped how American courts decide when to defer to legislatures and when to scrutinize them closely, authored opinions that still govern federal regulatory power and personal jurisdiction, and left behind a wartime record that scholars continue to criticize.
The Footnote That Built Modern Constitutional Review
Stone’s most consequential contribution to American law appears in a footnote. In United States v. Carolene Products Co. (1938), the Court upheld a federal ban on a type of processed milk product under a lenient standard that gave Congress the benefit of the doubt. The body of the opinion broke no new ground. Stone’s attached footnote, numbered four, quietly set the course of constitutional law for the next century.
The footnote proposed that courts should not always be so deferential. Stone identified three situations warranting stricter review:
- Laws that appear to violate a specific guarantee in the Bill of Rights.
- Laws that restrict the political processes citizens rely on to change bad laws, such as voting, speech, or political organizing.
- Laws that target religious, national, or racial minorities whose lack of political power makes the normal democratic process unreliable as a safeguard.
Stone asked whether “prejudice against discrete and insular minorities” might justify “a correspondingly more searching judicial inquiry.” The sentences read as tentative questions, not commands. Their effect was enormous.
The tiered scrutiny framework federal courts apply today traces directly to that footnote. Economic regulations receive a presumption of validity and survive if any rational basis supports them. Laws burdening fundamental rights or targeting vulnerable groups face strict scrutiny, requiring the government to prove a compelling interest pursued through narrowly drawn means. An intermediate tier covers certain classifications like sex. The hierarchy originated as marginalia on a dairy case.
Judicial Restraint and the Three Musketeers
Stone arrived at a Court still in the grip of what historians call the Lochner era, when the justices routinely struck down economic regulations on the theory that the Constitution protected a broad freedom to contract. Stone considered this the judiciary substituting its own economic preferences for those of elected legislators. His conviction was simple: if a law does not clearly violate a specific constitutional provision, the Court should leave it alone. A judge’s job is to assess constitutionality, not wisdom.
That philosophy put Stone opposite the Court’s conservative bloc, the “Four Horsemen” who voted repeatedly through the 1930s to invalidate New Deal legislation. Stone aligned with Justices Louis Brandeis and Benjamin Cardozo in a voting bloc the press dubbed the “Three Musketeers.” The three met at Brandeis’s apartment on Friday afternoons to coordinate before conference. In 1937 the Court began upholding New Deal statutes, and the rational basis approach Stone had championed in dissent became the default standard for economic legislation.
Expanding Federal Commerce Power: United States v. Darby
In United States v. Darby (1941), Stone wrote for a unanimous Court upholding the Fair Labor Standards Act, the federal law establishing a national minimum wage and maximum workweek. A Georgia lumber manufacturer argued that the Tenth Amendment reserved labor regulation to the states. Stone rejected that in blunt language, calling the Tenth Amendment “but a truism” that simply restates what the Constitution already makes clear. Powers not surrendered to the federal government remain with the states, but the commerce power is one that was surrendered. If a local activity substantially affects interstate commerce, Congress can regulate it. Darby gave Congress broad authority over labor standards nationwide and effectively overruled an earlier precedent that had tried to draw a sharp line between manufacturing and commerce.
Minimum Contacts: International Shoe Co. v. Washington
International Shoe Co. v. Washington (1945) reshaped civil procedure in a way every business operating across state lines still feels. A Missouri shoe company argued that Washington State had no authority to haul it into court there. Stone disagreed and established the “minimum contacts” standard: a state court may exercise jurisdiction over an out-of-state company when the company has enough connection to the state that requiring it to defend a lawsuit there would not offend “traditional notions of fair play and substantial justice.” A company that benefits from a state’s market should expect to answer in its courts.
The framework has proven remarkably durable. The Supreme Court refined it as recently as 2021 in Ford Motor Co. v. Montana Eighth Judicial District Court, holding that a company’s contacts with a state need not directly cause the plaintiff’s specific injury so long as the defendant’s activities in the state relate to the underlying dispute. The core insight Stone articulated in 1945, that jurisdiction follows meaningful commercial engagement, remains the governing principle.
Chief Justice During World War II
Roosevelt nominated Stone as Chief Justice on June 12, 1941, to succeed the retiring Charles Evans Hughes. Within six months, Pearl Harbor transformed the Court’s docket.
Stone’s leadership differed sharply from Hughes, who had run the conference with an iron hand and prized unanimous opinions. Stone preferred open debate. He let arguments run long and allowed the justices to hash out their disagreements in full. Dissents, once rare, appeared in more than half of decided cases under Stone. The justices he presided over were brilliant and combative, among them Hugo Black, Felix Frankfurter, William O. Douglas, and Robert Jackson, and Stone gave them room to fight. The intellectual output was impressive. The institutional cohesion suffered.
Wartime Civil Liberties: Quirin and Hirabayashi
The Stone Court faced some of the hardest questions a judiciary can face: how much liberty a government may sacrifice for wartime security. Stone’s record is complicated.
In Ex parte Quirin (1942), eight German-born men who had lived in the United States returned by submarine with explosives and instructions from the German High Command to sabotage war industries. They landed in civilian clothes and buried their military uniforms on the beach. Stone wrote for a unanimous Court that these men qualified as unlawful combatants and could be tried by military commission rather than civilian courts, even though civilian courts were open and functioning. United States citizenship did not shield an enemy belligerent from military justice when that person violated the laws of war.
Hirabayashi v. United States (1943) tested whether the government could impose a curfew exclusively on people of Japanese ancestry living on the West Coast. Stone again wrote for a unanimous Court and upheld the curfew as a valid exercise of the war power. He acknowledged that racial distinctions are normally irrelevant but concluded that “in time of war residents having ethnic affiliations with an invading enemy may be a greater source of danger than those of a different ancestry.” The Court treated the curfew as a protective measure justified by the importance of West Coast military installations and the perceived risk of sabotage.
The tension between Hirabayashi and Footnote Four is hard to miss. The footnote had called for heightened judicial scrutiny when laws target discrete and insular minorities. Japanese Americans were precisely such a minority. When wartime pressures arrived, Stone’s Court deferred to military judgment instead. Legal scholars have criticized the inconsistency ever since, and the broader internment program upheld in related cases is now widely regarded as one of the Court’s gravest errors.
Before the Court: Columbia and the Justice Department
Stone was dean of Columbia Law School from 1910 to 1923, where he championed the case method of legal education. After clashes with Columbia University President Nicholas Murray Butler, he resigned in 1923 and joined the Wall Street firm Sullivan and Cromwell. Private practice lasted less than a year.
President Calvin Coolidge appointed Stone Attorney General on April 7, 1924, when the Teapot Dome scandal and other Harding administration corruption had wrecked the Department of Justice’s reputation. Stone moved quickly. He forced the resignation of Bureau of Investigation Director William J. Burns, ordered a review of the entire Bureau’s personnel, directed that incompetent or unreliable agents be removed, and required future hires to have legal training and demonstrated good character. He also ordered the Bureau’s domestic intelligence operations shut down, concluding that a law enforcement agency had no business conducting political surveillance of American citizens.
Stone’s most consequential personnel decision was selecting a young career official named J. Edgar Hoover as acting director of the Bureau of Investigation, the agency that would become the FBI. Hoover’s reputation as an efficient administrator made him Stone’s pick, though Stone knew Hoover had played a major role in the controversial Palmer Raids as head of the General Intelligence Division.
Coolidge nominated Stone to the Supreme Court on January 5, 1925, less than a year after making him Attorney General.
Death
On April 22, 1946, Stone was reading an opinion from the bench when he became visibly ill. Two fellow justices helped him from the courtroom. A physician initially diagnosed the episode as indigestion, and Stone went home. He died there five hours later from a massive cerebral hemorrhage. He was seventy-three.
Stone’s body of work carries a productive contradiction. He believed deeply in judicial restraint and spent years arguing that courts should stay out of economic policy. He also recognized that restraint becomes abdication when legislatures target people who cannot protect themselves through politics. That balance, encoded in a single footnote to a forgettable case about processed milk, gave American constitutional law its modern structure.
