Summary

Portrait of John Marshall John Marshall Talbot v. Seeman — Opinion of the Court

The principle is that without benefit, salvage is not payable, and it is merely a consequence from this principle which exempts recaptured neutrals from its payment. But let a nation change its laws and its practice on this subject, let its legislation be such as to subject to condemnation all neutrals captured by its cruisers, and who will say that no benefit is conferred by a recapture? In such a course of things, the state of the neutral is completely changed. So far from being safe, he is in as much danger of condemnation as if captured by his own declared enemy.

Portrait of John Marshall John Marshall Talbot v. Seeman — Opinion of the Court

That the laws of a foreign nation, designed only for the direction of its own affairs, are not to be noticed by the courts of other countries unless proved as facts, and that this Court, with respect to facts, is limited to the statement made in the court below, cannot be questioned. The real and only question is whether the public laws of a foreign nation on a subject of common concern to all nations, promulgated by the governing powers of a country, can be noticed as law by a court of admiralty of that country or must be still further proved as a fact.
