Summary

Samuel Nelson Mauran v. Insurance Company — Opinion of the Court

And the United States cannot at the same time insist that they have the belligerent rights which by the law of nations belong to a sovereign waging public war, and yet assert that there is no such public war as is known to the law of nations. That it is a civil war, does not change the rule of the law of nations respecting those who carry it on. [9]
Any capture or seizure, whether rightful or wrongful, and whether made under a commission from a de jure, or de facto government, or made by mere pirates, is equally within the warranty in this case.

Samuel Nelson Mauran v. Insurance Company — Opinion of the Court

In whatever light they may be to be looked on by the courts of foreign powers, certainly all cruisers, under the flag of whatever combination of persons, are, in all courts of the United States, to be regarded as pirates by the law of nations, unless such persons have been recognized by the Executive as lawful belligerents, and so a de facto government.
