In the case of United States Ex Rel. Giese v. Chamberlin, Commanding General, et al., 1951, the Supreme Court was asked to determine whether a U.S. citizen could be drafted into military service while residing in a foreign country (Germany). The petitioner, Giese, argued that he should not be subject to conscription as he had been living abroad since childhood and did not maintain significant ties with the U.S. However, his claim was rejected by lower courts on grounds that citizenship alone sufficed for draft eligibility regardless of residence location. The Supreme Court upheld these rulings stating that Congress has authority under its constitutional war powers to draft citizens wherever they may reside globally. It further clarified that physical presence within national borders is not required for jurisdiction over citizens regarding obligations imposed by law including military service requirements. This decision affirmed broad interpretation of Congressional power concerning national defense matters and emphasized responsibilities accompanying US citizenship irrespective of geographical location.

In the dissenting opinion for United States Ex Rel. Giese v. Chamberlin, Commanding General, et al., Justice Douglas argued that the majority's decision to deny habeas corpus relief was incorrect and violated constitutional principles. He contended that a military court did not have jurisdiction over civilians in peacetime under any circumstances, even if they were accompanying armed forces abroad as dependents of service members. According to him, this principle should hold true regardless of whether or not Congress had declared war formally because it is rooted in fundamental civil liberties protected by the Constitution itself - specifically those related to due process and trial by jury rights under civilian courts rather than military tribunals. Furthermore, he criticized the majority's reliance on international law arguments about occupied territories' status during wartime since these didn't apply given there was no formal declaration of war at hand.
