## Facts

- Twenty-one German nationals served in a German intelligence and support group in China during World War II.
- After Germany’s unconditional surrender (May 8, 1945), they continued to assist Japanese forces against the United States and its allies until Japan’s surrender (Aug. 15, 1945).
- A U.S. military commission in Shanghai tried them for violating the laws of war by continuing hostilities after Germany’s surrender and by providing aid and intelligence to Japan.
- The commission convicted them and imposed prison sentences.
- The United States transported them to Landsberg Prison in the American-occupied zone of Germany, where U.S. Army personnel held them in custody.
- None of the prisoners had ever been present in the United States or in territory incorporated into the United States.
- They sought habeas corpus in the U.S. District Court for the District of Columbia against senior Defense Department and Army officials, alleging constitutional, statutory, and Geneva Convention violations.
- The district court dismissed for lack of jurisdiction; the D.C. Circuit reversed; the Supreme Court granted review.

## Issues

1. Whether U.S. courts have habeas jurisdiction over petitions filed by nonresident enemy aliens who were captured, tried, convicted, and imprisoned outside U.S. sovereign territory.
2. Whether such prisoners may invoke the U.S. Constitution or the 1929 Geneva Convention to obtain judicial review in U.S. civil courts of their military commission convictions and detention abroad.

## Decision

- The Supreme Court reversed the D.C. Circuit and reinstated dismissal of the habeas petitions.
- The Court held that nonresident enemy aliens captured, tried, and held abroad had no right to seek habeas relief in U.S. courts.
- The Court emphasized that constitutional protections previously extended to aliens were tied to presence within U.S. territorial jurisdiction.
- The Court distinguished prior military-commission habeas cases on the ground that those detainees were held within areas under U.S. sovereignty.
- The Court rejected reliance on the 1929 Geneva Convention as a basis for judicially enforceable habeas rights in these circumstances, treating compliance and enforcement as matters for political and military authorities.
- Dissenting justices would have permitted habeas review because the prisoners were held under complete U.S. control and constitutional limits constrain the government wherever it acts.

## Legal Principles

- U.S. courts lack jurisdiction to entertain habeas corpus petitions by nonresident enemy aliens who have never been in U.S. sovereign territory and whose capture, trial, and confinement occurred abroad.
- Constitutional guarantees generally do not extend, for habeas-access purposes, to enemy aliens outside U.S. territorial jurisdiction who remained aligned with enemy forces.
- In wartime, the Executive’s control over enemy aliens is afforded substantial deference; judicial review is not available to expand access beyond narrow, historically recognized limits.
- Treaty provisions concerning treatment of war detainees do not necessarily create privately enforceable judicial remedies in U.S. courts absent clear authorization.

## Conclusion

The Court concluded that nonresident enemy aliens convicted by a U.S. military commission abroad and imprisoned abroad could not invoke U.S. civil habeas jurisdiction or constitutional protections to challenge their detention, and that treaty-based compliance questions were principally for political and military authorities rather than domestic courts.
