Constitutionality of Japanese American Internment Camps

The constitutionality of the WWII Japanese American internment remains a settled historical injustice with a complex legal trajectory.

Executive Order 9066 (Feb 19, 1942)

Authorized military exclusion zones → forced removal of ~120,000 Japanese Americans (2/3 U.S. citizens) from West Coast to 10 War Relocation Authority camps.

Supreme Court: Korematsu v. United States (1944)

• 6–3 decision: Upheld exclusion order as constitutional "military necessity."
• Dissents (Murphy, Jackson, Roberts): Called it "legalization of racism," violation of equal protection.

Post-War Reckoning

• 1980s: CWRIC (Commission on Wartime Relocation) found "race prejudice, war hysteria, failure of political leadership"—not military necessity.
• 1988: Civil Liberties Act – formal apology + $20,000 reparations to surviving internees (signed by Reagan).
• 2011: DOJ officially conceded Solicitor General suppressed evidence in Korematsu.
• 2018: Trump v. Hawaii (travel ban case) – Roberts Court: "Korematsu was gravely wrong the day it was decided," effectively overruling it.

Consensus Today

Internment violated the 5th Amendment (due process), 14th Amendment (equal protection), and fundamental civil liberties. Korematsu stands as an anti-canon—a warning against racial profiling under guise of national security.

No Japanese American was ever convicted of espionage or sabotage. The camps were unconstitutional then; they are unequivocally condemned now.
