Portrait of Joseph Story Joseph Story The Marianna Flora — Opinion of the Court

Pirates may, without doubt, be lawfully captured on the ocean by the public or private ships of every nation; for they are, in truth, the common enemies of all mankind, and, as such, are liable to the extreme rights of war. And a piratical aggression by an armed vessel sailing under the regular flag of any nation, may be justly subjected to the penalty of confiscation for such a gross breach of the law of nations. But every hostile attack, in a time of peace, is not necessarily piratical. It may be by mistake, or in necessary self-defence, or to repel a supposed meditated attack by pirates.

One of the privileges of a state of peace, which the Portuguese have still a right to maintain for themselves, is the benefit of the principle, that on the high seas the merchantman is equal to the man-of-war. Each may protect itself according to its sense of expediency and necessity, and resist the doing of any thing by the other, as a right, which is not a right. If the man-of-war has no right to examine, the merchantman has a right to resist that examination. Even in war, a vessel navigating the ocean may, to a certain extent, draw a line of jurisdiction around itself.

It goes to establish upon the ocean a territorial jurisdiction, like that which is claimed by all nations within cannon shot of their shores, in virtue of their general sovereignty. But the latter right is founded upon the principle of sovereign and permanent appropriation, and has never been successfully asserted beyond it. Every vessel undoubtedly has a right to the use of so much of the ocean as she occupies, and as is essential to her own movements. Beyond this, no exclusive right has ever yet been recognised, and we see no reason for admitting its existence.
