Korematsu v. United States

No. 22 (October Term 1944) SCOTUS · Decided Teaching/Historical SCOTUS
Argued: Oct 11, 1944 Decided: Dec 18, 1944


The Facts

Fred Korematsu, a Japanese American citizen, refused to comply with military exclusion orders removing persons of Japanese ancestry from the West Coast during World War II. He was arrested and convicted of violating Exclusion Order No. 34. Korematsu appealed, arguing the order violated his constitutional rights.

The Issue

Whether military exclusion orders targeting persons of Japanese ancestry during wartime violate the Equal Protection component of the Fifth Amendment's Due Process Clause. Whether the government's asserted military necessity justified the racial classification and internment.

The Rules

U.S. Const. amend. V Fifth Amendment Due Process Clause

No person shall be deprived of life, liberty, or property, without due process of law. The equal protection component bars invidious racial discrimination.

Executive Order 9066 Presidential Authority During Wartime

President Roosevelt's executive order authorized military commanders to designate military areas and exclude any persons deemed necessary for national security during wartime.

Korematsu v. United States, 323 U.S. 214 (1944) Racial Classifications and Strict Scrutiny

All legal restrictions which curtail the civil rights of a single racial group are immediately suspect and must be subjected to rigid scrutiny. However, pressing public necessity may justify racial classifications in wartime military contexts.

The Application

History

The Court applied strict scrutiny to the race-based exclusion order but found that military necessity during wartime satisfied this demanding standard. Korematsu, a U.S. citizen, was ordered excluded solely because of his Japanese ancestry (a direct racial classification) yet the Court upheld the order by according substantial deference to military judgments about wartime security needs. Under this framework, the Court effectively subordinated Korematsu's equal protection rights to military authority, establishing that extreme wartime exigency could override ordinary constitutional protections for racial minorities.

The Conclusion

The Supreme Court, in a 6-3 decision, upheld Korematsu's conviction and the constitutionality of the exclusion order. The Court held that pressing public necessity during wartime could justify racial classifications, applying the most deferential judicial review to military decisions. The decision established that race-based governmental action receives strict scrutiny, but the Court found military necessity satisfied even this demanding standard a holding later criticized and distinguished in subsequent cases.

Case Analysis

Overview

The Court upheld the military's internment of Japanese Americans during WWII as a constitutional exercise of war powers, despite racial classification.

Facts

Fred Korematsu, a Japanese American citizen, refused to comply with military exclusion orders removing persons of Japanese ancestry from the West Coast during World War II. He was arrested and convicted of violating Exclusion Order No. 34. Korematsu appealed, arguing the order violated his constitutional rights.

Issue

Does the federal military's authority during wartime justify race-based exclusion orders targeting an entire ethnic group, even when applied to American citizens? Does racial classification in a military exclusion order satisfy strict scrutiny review under the Equal Protection component of the Fifth Amendment's Due Process Clause?

Rule

All legal restrictions on civil rights of a single racial group are immediately suspect and must be subjected to the most rigid scrutiny (establishing strict scrutiny standard). Though the Court held this order satisfied it. Military necessity can justify race-based classifications in extreme wartime circumstances, but this reasoning was expressly repudiated in Trump v. Hawaii (2018) as 'objectively unlawful' and inconsistent with the Constitution.

Analysis

The Court applied strict scrutiny to the race-based exclusion order but found that military necessity during wartime satisfied this demanding standard. Korematsu, a U.S. Citizen, was ordered excluded solely because of his Japanese ancestry, a direct racial classification, yet the Court upheld the order by according substantial deference to military judgments about wartime security needs. Under this framework, the Court effectively subordinated Korematsu's equal protection rights to military authority, establishing that extreme wartime exigency could override ordinary constitutional protections for racial minorities.

Conclusion

**The Supreme Court, in a 6-3 decision, upheld Korematsu's conviction and the constitutionality of the exclusion order.** The Court held that pressing public necessity during wartime could justify racial classifications, applying the most deferential judicial review to military decisions. The decision established that race-based governmental action receives strict scrutiny, but the Court found military necessity satisfied even this demanding standard. A holding later criticized and distinguished in subsequent cases.

Notes

1944 decision upholding Japanese American internment. Formally abrogated by Trump v. Hawaii (2018). Bryan uses as equal protection + strict scrutiny teaching case and cautionary precedent.
