Article I, Section 8, Clause 11:
[The Congress shall have Power . . . ] To declare War, grant Letters of Marque and Reprisal, and make Rules concerning Captures on Land and Water; . . .
The Civil War prompted a number of Supreme Court cases concerning the breadth of the federal government’s war powers. In Hamilton v. Dillin, the Supreme Court addressed a challenge to licensing fees the executive branch imposed under a Civil War-era statute that authorized trade restrictions on commercial exchanges with states declared to be in an insurrection.[1](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/civil-war-and-executive-and-legislative-powers#fn1art1 "
88 US. (21 Wall.) 73, 86–87 (1874)
(discussing Act of July 13, 1861 § 5, 12 Stat. 257 ). The Court stated “there can be no question” that the executive branch’s fees were “competent to the war power of the United States government to impose.” [2](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/civil-war-and-executive-and-legislative-powers#fn2art1 "
The Supreme Court also upheld the constitutionality of other Civil War-era economic measures as valid exercises of congressional power. In Miller v. United States, the Supreme Court deemed constitutional a set of statutes authorizing seizure and confiscation of Confederate property without a jury trial, reasoning that “the power to declare war involves the power to prosecute it by all means and in any manner in which war may be legitimately prosecuted.” [6](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/civil-war-and-executive-and-legislative-powers#fn6art1 "
Miller v. United States,
78 U.S. (11 Wall.) 268 , 304–05 (1870)
. The Court also upheld the 1862 Legal Tender Act,[7](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/civil-war-and-executive-and-legislative-powers#fn7art1 " 12 Stat. 345 (1862). ") in which Congress authorized production of paper currency as a part of a response to the economic crisis caused by the Civil War.[8](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/civil-war-and-executive-and-legislative-powers#fn8art1 "
Although the Supreme Court upheld government action in several Civil War-era cases, not every exercise of the Union war effort withstood judicial scrutiny. In Ex parte Milligan, the Supreme Court addressed whether an Indiana man could be tried in a military commission created by presidential order, rather than a federal court, for conspiring to commit acts of sabotage and fomenting rebellion in states under Union control.[9](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/civil-war-and-executive-and-legislative-powers#fn9art1 "

The accused argued that he had been denied his constitutional rights to habeas corpus,[10](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/civil-war-and-executive-and-legislative-powers#fn10art1 " See . ") trial before jury,[11](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/civil-war-and-executive-and-legislative-powers#fn11art1 " See . ") and to have his case heard in a judicial tribunal created under Article III of the Constitution.[12](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/civil-war-and-executive-and-legislative-powers#fn12art1 " For background on the relationship between military tribunals created under Article I of the Constitution and federal courts created under Article III, see . ") The United States responded that the President possessed broad war-time emergency powers justifying trial in a military tribunal, even going so far as to argue that “[d]uring the war [the President’s] powers must be without limit.” [13](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/civil-war-and-executive-and-legislative-powers#fn13art1 " Argument in the Supreme Court of the United States on the Side of the United States,
The Supreme Court rejected the United States’ far-reaching assertion and held that the accused could not constitutionally be tried in a military commission, in part, because federal courts were not obstructed from operating in Indiana at the time of his trial.[14](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/civil-war-and-executive-and-legislative-powers#fn14art1 " See
Ex parte Milligan,
71 U.S. (4 Wall.) at 121
. The Milligan Court also held that, even if Congress had passed legislation authorizing the military commission in question, Congress had no constitutional power to authorize trials of American civilians in areas where federal courts are open and unobstructed.[15](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/civil-war-and-executive-and-legislative-powers#fn15art1 " See
Milligan marked a departure from an earlier Civil War case, Ex parte Vallandigham, in which the Supreme Court concluded that it did not have jurisdiction to resolve an Ohio civilian’s challenge to conviction in a military commission.[16](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/civil-war-and-executive-and-legislative-powers#fn16art1 "
Ex parte Vallandigham,
68 U.S. 243 , 251–52 (1863)
. In that case, a military commission had convicted Clement Vallandigham, a former Member of Congress and vocal opponent of Union participation in the Civil War, of violating a prohibition on “declaring sympathies for the enemy.” [17](https://www.law.cornell.edu/constitution-conan/article-1/section-8/clause-1/civil-war-and-executive-and-legislative-powers#fn17art1 "
