Whether an American civilian who commits an offense in a foreign country has a constitutional right to trial in an Article III court with grand and petit juries.
Holding
No. The Constitution did not require an Article III court or jury trial for this civilian's offense committed abroad in Japan.
Reasoning
The Court treated the Constitution as operative abroad but distinguished between the Constitution's existence and the applicability of a particular constitutional guarantee. The relevant question was whether Article III and the jury-trial provisions required a particular form of court for an American citizen tried in a foreign country.
Longstanding precedent recognized Congress's authority to create legislative courts outside the United States proper. Decisions concerning unincorporated territories, as well as In re Ross, established that such tribunals could try Americans abroad without adhering to Article III's requirements or providing grand and petit juries.
Because Congress could constitutionally establish a territorial or consular-style legislative court in Japan to try Smith, her circumstances did not create a constitutional entitlement to an Article III criminal trial. The Court therefore distinguished Toth v. Quarles, where military jurisdiction over a discharged serviceman in the United States displaced the ordinary Article III jury-trial system.
